The tips may be flat, serrated, cupped, ringed, grooved, diamond dusted or have teeth. The tips may also be straight, curved or angled. See the images below. Serrated tweezers thumb forceps are designed for use with tissues. The serrations or teeth actually cause less damage than flat forceps, because it requires less pressure to maintain a firm grip.
Use smooth or cross-hatched forceps for removing sutures, moving dressing or other drapes. Commonly used thumb forceps include Adson forceps, Iris forceps and Foester forceps. Locking forceps may be called clamps and are used to securely hold tissue. When they are used to control blood flow, they are called hemostats.
When used to grasp and manipulate needles, they are called needle holders. Hemostatic Forceps. Ring forceps also called hemostatic forceps are hinged and look like ring scissors. Frequently, hemostatic forceps have a locking mechanism called a ratchet, which is used for clamping.
The jaws of the locking forceps gradually come together as each increment of the ratchet is employed. Ring forceps are used for grasping, holding firmly or exerting traction upon objects. For especially delicate operations, generally ring handles with a locking ratchet are preferred over thumb forceps. Locking hemostatic forceps may be called clamps and are used to securely hold tissue. Hemostats are typically used to compress blood vessels or other tubular structures to obstruct the flow of blood or fluids.
The jaws can be straight, curved or right angle. They come in a variety of sizes depending on your application. For example, Mosquito hemostats clamp small blood vessels, and Kelly hemostats can be used to clamp larger vessels or grasp tissue. Kelly hemostats and Rochester forceps look similar. However, Kelly hemostats have shorter serrations. Rochester hemostats can reach a little deeper. Left Handed Scissors. Left hand scissors allow left-handed people: To be as precise as right-handed users, especially in delicate applications when results are critical.
To use natural actions without a second thought. To use instruments with smooth, even action. To have the maximum control of their instruments. Instruments like scissors, needle holders and other instruments with a ratchet action require a lateral movement for use. For right-handers the action is natural. In the case of needle holders with a ratchet closure, the right-hander uses the right thumb to push the upper blade out and away, disengaging it. The same instrument held in a left hand requires the user to pull the top blade in an unnatural action in order to disengage it.
The awkward nature of the movement can make it less fluid. When using a pair of right hand scissors, the action is also natural and subconscious for right-handed people.
With a pair of right hand scissors, the right blade is on the top, regardless of which hand you hold the instrument in. For a right hander, this offers great visibility of the cutting material.
The action of a right-handed person squeezing the blades together using the index finger and the thumb causes the blades to come closer together and sheers the material being cut.
This is not true for a left-handed person holding right hand scissors. First, the left-hander must look awkwardly over the scissors to view the cutting edge. Then, he or she must compensate for the unnatural action, as the right hand scissor blades tend to splay apart when squeezed with a left hand. Looking for scalpels or surgical knives for your research laboratory? We have disposable knives, sapphire blades, and standard scalpel blades and blade handles.
Scissors are cutting tools with two blades joined in the center such that the sharp edges of the blades slip into each other.
WPI offers many choices. Doyan Rib Rasp — With a long neck, comfortable handle, and horizontal hook, the Doyen rib raspatory is designed for cardiothoracic surgeries. Suitable for righties, lefties, adult sized patients and smaller ones too, this silver fox has the ability to hold or scrape away at ribs.
Fogarty Clamp — The Fogarty clamp is not just another atraumatic tissue gripper. This clamp is surfaced with rubber-shod serrated blades that allow for an atraumatic grip on tissues and blood vessels. This rubber-shod is a disposable piece and should not be reused for different patients. Frazier Suction Tube — Invented and named after Michael Frazier, this thin tool is used for suctioning out fluids from cavities in the most precise way. The shaft is made of flexible material, to allow for different and bendable positions during the procedure.
If left undealt with, fluids and other materials may begin to build up and hinder the process of surgery. With the Frazier suction tube, the wound is able to stay dry and clear, as the adjustable tool refrains from interfering.
Often used in cardiothoracic procedures, this tissue grasper comes in light to intermediate weight, and a stop peg to assure that tissues are delicately handled. Jorgenson Scissors — Used for getting deep into tissues, these snappers come with a long handle and a curved blade for procedures such as hysterectomies. Bulldog Clamp — This versatile tool comes in a variety of shapes, sizes, and curvatures that allow surgeons to reach difficult and distant blood vessels.
When the handles are squeezed, the clamp opens up, and when the pressure is released, the clamp shuts down, therefore preventing patients from losing blood. Bulldog clamps can range from 2. Israel Retractor — The Israel retractor may not solve problems in the middle east, but it will handle heavy tissue in orthopedic surgeries. The blades resemble a rake, and, like most retractors, this tool is used to retain edges on an incision, wound, organ, or tissue.
Iris Scissors — These fine scissors with a very sharp tip are delegated to ophthalmic surgery, but can most likely be found being used during other medical procedures and as a part of autopsy tool kits and more. In fact, they are so easy and fun to use that they have made a name for themselves even in the world of non medical practices such as crafts.
Both closed and open shank versions are available on the market. The goal with these is to keep them as sharp as possible, which will make the craft or surgery process more precise. Those interested in using these scissors can find a pair suitable for the right or left hand, for optimal control. It is important to keep the moving parts oiled and those used for medical purposes must be sterilized with antiseptic soap and an autoclave, and stored in a safe place, possibly with the tips covered.
Mosquito Clamp — Think small. The mosquito clamp is typically found to be between 3 inches to 5 inches in length, and is considered to be one of the smaller hemostatic forceps. These clamps are one of many hemostatic forceps, and no, they are not used to catch mosquitos, but small blood vessels in order to control bleeding.
Mosquito forceps, with their blunt grip, manage small blood vessels but are not set out to do any damage or trauma. Tips may be straight or curved, but regardless of the shape, these clamps, along with most hemostatic forceps, will most likely include a locking feature that will allow doctors to work with more liberty.
These instruments will most likely be found in stainless steel or carbon steel, in which case they will be able to be reused after sterilization.
In other cases, the tool may be found in disposable plastic, but will only be able to used once. Kelly Clamp — The Kelly clamp, which is much more elongated, and also known as the Rochester Pean, is used to clamp larger vessels and tissue. Mosquito clamps are considered to be smaller and daintier types of Kelly forceps, which have the same function but aim at larger sized vessels and tissues during procedures.
These too are typically made from stainless steel, or other forms of high quality steel, and should be sterilized in hot water and chemicals, if they are to be reused.
They can also be found in reusable plastic but should only be used once in this form. Burlisher Clamp — Can you tell the difference between this clamp and the others? Also known as the Adson forcep and the Schnidt tonsil forcep, this instrument is used to clamp deep blood vessels. The burlisher has two closed finger rings, and if they are found with an open finger ring, the tool would be known as a tonsil hemostat. Tonsil Hemostats — Similar to the burlisher clamp, which has two closed finger rings, the tonsil hemostat has open finger rings and a catch for locking the blades.
These forceps are able to control hemorrhage by getting a grip on the end of blood vessels. Used both in general surgery as well as neurosurgery, these forceps are typically found at a length of seven to nine inches, formed completely with stainless steel. The goal for a surgeon is to perform an operation with little to no tissue damage, in which case the tonsil hemostat forcep is the perfect tool, as the two finger rings make handling the instrument an easy task.
In tonsil related operations, the tool is used to remove affected pieces when necessary. Right Angle Forceps — You guessed it. This tool features a right angle to reach vessels that are out of the way and to place sutures in particular places in relation to vessels. Hurd Dissector — This two-faced tool, also known as the Hurd tonsil dissector and Pillar retractor is a double ended tool used in oral procedures and tonsillectomies.
One side has a retractor lip end, while the other side is a sharp and rounded end for dissecting. Hoke Osteotome — This tool is used during neurosurgery and has a straight and sturdy handle, a dip found three quarters of the way through, and a flat blade perfect for cutting bone and preparing to cut bone.
Ranging from 3. Yankauer Suction Tip — Created in by American doctor Sidney Yankauer, this firm but bendable plastic oral suction tool is used to remove secretions. Watch the blood slide down the lightly tinted blue tube. This procedure is typically accompanied with sutures. The loose facial and neck skin is then pulled back. Ballantine Clamp — Who do you call when you need to clamp and sever a tough ligament from both sides of the uterus?
Anyone with a Heaney-Ballentine clamp, of course. This tool falls under the category of heavy clamps, as it has a rigid shaft and vertical serrations that can crush parametrial and paracervical tissue during hysterectomies, for instance. Heaney Needle Holder — Another tool you might see in a hysterectomy, along with dilation and curettage, the Heaney needle holder uses ratcheted blades for medium weight suturing.
This holder can just as well be used as a cardiovascular approximation and closure instrument. Heaney-Simon Vaginal Retractor — This peculiarly shaped instrument has a grooved handle that controls a smooth flat blade that curves up into a right angle. Vaginal retractors such as the Heaney-Simon retractor or the Miyazaki retractor, which both fall under the category of vaginal handheld retractors, can be used in the deep pelvic surgery and are made comfortable for handling.
Hemoclip Applier — This tool can be used in any surgery and is more commonly seen in vascular surgery to gain hemostasis, the stopping of blood flow, with the use of a hemoclip. The tool should not be squeezed with the hemoclip until the desired vessel is prepared and in the correct position. Hoen Elevator — Used for neurosurgical procedures, this tool is used to move mainly soft tissue and bone if necessary.
Coming in different sizes, the Hoen elevator also features a somewhat sharp edge if dissection is on the table. Javid Carotid Clamp — Have an artery that needs clamping during a cardiothoracic surgery? The Javid carotid clamp, a. When brought together, the two sides are perfect for clamping around an artery. Knight Scissors — Talk about a knight in shining armor, these Knight scissors are typically made with tungsten carbide inlays, one side matching a standard blade and the other one featuring micro-serrations.
Often used for rhinoplasties, these scissors fit nicely into the nasal cavities. Kocher Clamp — This hemostat has interlocking tip teeth that are used to grab bone or fascia.
Emil Theodor Kocher, inventor of the Kocher clamp in , used the instrument to prevent blood loss during surgery. The Swiss surgeon was awarded a Nobel Prize in for his contributions. These forceps may be straight or curved and has a tooth at the end of one blade and a groove in the other for optimal blood prevention and tissue slippage. K-Wire Cutter — This handy dandy tool can be used all over the place, but is designed to cut wire in a perpendicular fashion. Derived from Martin Kirschner, who introduced the Kirschner wire in , K-wires are used for fixation during operations.
These wires may pass through skin and into bone. Trocar — A trocar is an instrument with a three sided cutting point enclosed in a tube which gives access to the abdominal cavity during a laparoscopic operation. It is made up of three main parts which include the cannula, the seal, and the obturator. The seal is on top of the cannula and allows instruments to pass through without letting air escape. Finally, the obturator allows the cannula to penetrate the abdomen. Following the incisions, trocars are placed inside and passed through.
Littler Scissors — Are these scissors littler than yours? A hole in the blade allows suture material to be passed and carried. Fine tissue may also be dissected with these finger ring scissors. Mayo-Hegar Needle Holder — Number sixty three on our list but certainly not least, this versatile tool comes in different sizes and is one of the most popular surgical instruments, as seen in oral, gynecological, bariatric, and dermatological procedures.
Metzenbaum Scissors — Designed by American surgeon Myron Firth Metzenbaum, these cutters are most commonly used in organ and heart operations, as the long shanks are ideal for cutting delicate tissue and performing blunt dissections.
Nasal Rasp — In the case where a patient is experiencing problems with breathing, a nasal rasp has the ability to scrape out foreign bodies or other sources of discomfort during a rhinoplasty. Although probably not the best tool for seeing your own reflection, the nasal speculum acts to spread the nostrils, so that the inside can be more easily seen, examined, and worked on.
Nerve Hook — No hook for a captain, but a fine one for a surgeon, the nerve hook is meant for neurosurgical procedures that call for movement or retraction of nerves and soft tissues. With no sharp edges, this is not a tool out to do any damage. Penfield 1 — Manipulate tissue, scoop small bone, or dissect with the tip. The bottom is curved and only semi-sharp. Penfield 2 — Very similar to the penfield 3, the penfield 2 has a curved but more straight edged tip. The bottoms look almost identical, and can both be used to press bone wax into bleeding bone.
Penfield 3 — As stated above, this instrument is hard to differentiate from its former tool, the penfield 2. Remember that this one has a more rounded tip. Penfield 4 — Used in general surgery, neurosurgery, and more, this gentle tool is used for poking or moving tissue, and acts as an extension of your finger, allowing a fuller understanding of which tissue is being touched. Perforating Towel Clamp — If only your hands could do all the work.
Luckily, the non offensive and non penetrating towel clamps are here to hold your towels, instruments, tissues, and just give you a hand. Poole Suction — After irrigating the abdominal cavity, use this tool to suck up fluid. Potts Scissors — These elongated finger ring scissors with a sixty to ninety degree angle are great for trimming and opening vessels in procedures around the chest.
Putti Rasp — This double ended shovel shaped instrument is a bone rasp with curved, pointed rasp surfaces at both ends. It is ideal for procedures that include gentle bone reshaping, found in neurosurgical or orthopedic surgeries. It has a narrow and sleek design that allows this tool to be fit into small spaces while affecting bone or tissue from a number of angles. Ragnell Retractor — This tool too is a double ended double bladed piece, falling under the retractor family.
Commonly used in orthopedic operations, this instrument can be used to lift parts that hold down organs or tissues. Rat Tooth Forceps — A rat tooth suggests the intermeshing of tips on surgical instruments when they are brought together. This texture allows a good hold on tissue or other items while not causing too much damage. A large dial moves the claws, and holds tight throughout the procedure.
This rodent tool has the strength to open bone and is often used in neurosurgery, podiatric surgery, and orthopedic surgery to open up the areas that are to be operated on. This rongeur is destiquishible by the square jaw and comfortable grip. It is a stainless steel tool. Scapula Retractor — Did a monster crush this spatula? No, the design is intentional, as each part of this angled tool serves a significant purpose.
Beginning with the ribbed handle, gripping is made comfortable and secure. The bent blade gives a stable hold, which donates secured access to the work area, and the slots in the blades serve to minimize stress on the bone. Senn Retractor — This is not the dinner table and that surgical instrument is certainly not a fork. The Senn retractor is used to hold back surface tissue with sharp but blunt prongs. At the other end, find an angled, blunt end. Sickle Knife — Used in procedures such as tonsillectomies and adenoidectomies, this tool can cut the mucosa and submucosa which can aid in elevation in tonsillectomy and adenoidectomy procedures.
The tip which is found to be blunt is designed to cause as little damage to surrounding tissue as possible. Sims Retractor — This tool is used in vaginal procedures to retract the anterior wall and expose the posterior wall by dilating the vagina.
This gives the gynecologist a clear view of the body cavity so that he or she may understand what is happening and what to do next. When it comes to gynecological instruments, plastic materials are common, as they may only be used once. However, the sims retractor also comes available in stainless steel, in which case they must be sterilized after every use.
These tools come in a variety of sizes to fit each patient appropriately. Frontal Sinus Curette — This curette allows for exploration and scraping of tissue in the nasal cavity. Mayo scissors may also be used to cut sutures and heavy body tissues. Costotome — A Costotome is a specialized rib cutter used to gain access to the thoracic cavity. Unpowered — In many applications, the saw is used in specialized jigs to provide accurate, measurable cuts, e.
Grasping and holding instruments are used to hold tissue, drapes or sponges. Examples include Forceps, Towel Clamps, vascular clamps, and organ holders.
Surgeons use forceps during surgical procedures to hold onto or manipulate tissues and to clamp blood vessels. Surgical forceps are hinged instruments, similar in design to scissors, but with tong-like or flat tips that are used to hold, clamp or move tissues during surgery. A towel Clamp is a perforating clamp used for grasping tissue, securing towels or drapes and holding or reducing small bone fractures.
A needle holder, also called a needle driver, is a surgical instrument, similar to a hemostat, used by doctors and surgeons to hold a suturing needle for closing wounds during suturing and surgical procedures. The parts of a simple needle holder are the jaws, the joint and the handles.
Most needle holders also have a clamp mechanism that locks the needle in place, allowing the user to maneuver the needle through various tissues. This is another class of surgical instruments that are used in occluding blood vessels and help control bleeding during a surgical operation. It is specifically designed to catch the bleeder that is deep within tissue hence it is ideally used on tough structures like palms, soles or scalp.
The forceps catch the structure that is bleeding and crush the bleeder that resulting in clogging. The tooth gripped the structure firmly so that the tissue does not slip. Kelly forceps are a type of hemostat usually made of stainless steel. They resemble a pair of scissors with the blade replaced by a blunted grip.
They may be either curved or straight. In surgery, they may be used for occluding blood vessels, manipulating tissues, or for assorted other purposes. They are used during surgery to compress the artery, clamp and seal small blood vessels or manipulate the artery.
