 COMMON SURGICAL INSTRUMENTS The operating room contains a multitude of instruments fit for accomplishing a number of procedures. Note that this is not an exhaustive list of instruments, but rather some that you will encounter frequently. SCALPEL Used for initial incision and cutting tissue. Consists of a blade and a handle. Surgeons #10 Blade: Used primarily for #11 Blade: Used for making #15 Blade: Smaller version of often refer to the making large skin incisions, precise or sharply angled #10 blade used for making finer instrument by its blade e.g., in laparotomy. incisions. incisions. number. Pott’s Scissors: Fine scissors used for creating SCISSORS incisions in blood vessels. Used for cutting tissue, suture, or for Iris Scissors: Used dissection. Scissors Mayo Scissors: Heavy scissors Metzenbaum Scissors: Lighter for fine dissection available in multiple varieties. scissors used for cutting delicate can be straight or and cutting fine Straight scissors are used for tissue (e.g., heart) and for blunt curved, and may be suture. Originally cutting suture (“suture scissors”), dissection. Also called “Metz” in used for cutting heavy for ophthalmic while curved scissors are used practice. or finer structures. procedures, but for cutting heavy tissue (e.g., now serves fascia). multipurpose role.

They come in various sizes, types, and and #11-0. Higher numbers suture. The first is braided and NEEDLES & shapes depending on the application. Here are a indicate larger suture non-braided, or monofilament. few (though not all) examples: diameter (e.g., #3 is larger The second is absorbable and SUTURE than #2), and more zeros non-absorbable. Additionally, Needles come in many indicate smaller suture suture can be made with shapes and cutting diameter (e.g., #4-0, or natural or synthetic materials. edges for various #0000, is smaller than #3-0, Some (brand) names and uses applications. Suture or #000). are shown below. can be absorbable, non Tapered Needle Conventional Cutting Needle is round and Needle Suture Types absorbable, and is tapers to a simple point. Needle is triangular with Absorbable Non-Absorbable available in different Most commonly used in sharp edges, and one edge Braided Monofilament Braided Monofilament sizes. softer tissue such as faces the inside of the intestine but may also be curved needle. Used for Vicryl® Monocryl® Silk Prolene® used in tougher tissue tougher tissues such as Polysorb® Maxon® Surgipro® such as muscle. skin. PDS® Monosof® Needle Shape Chromic gut Nylon The shape of the needle is also important. The curvature of the needle allows for use in Internal Fascial closure Vessel ligation Skin closure specialized applications. Curved needles are used Skin Glue and anastomosis Subcuticular Reapproximate in most general surgical procedures, while straight Staplers skin closure lacerations needles are used for skin and subcuticular suturing. For skin closures, in particular, staplers and skin glue may be used in lieu of suture. This is usually based on cosmetic outcome and surgeon preference. RETRACTORS In varying forms, retractors are used to hold an incision open, hold back tissues or other objects to maintain a clear surgical field, or reach other structures. They can Deaver Retractor: Army-Navy Retractor: Weitlaner Retractor: Self- Richardson Retractor: Bookwalter Retractor: Used to hold back Used to gain exposure retaining for exposing deep Used to hold back deep Self-retaining retractor either be hand-held or the abdominal wall. of skin layers. or smaller surgical sites. tissue structures.

It can Yankauer Suction Poole Suction Tube: Frazier Suction Tip: Can be bent and Hand-held retractor also be used to clear Tube: Used Used to remove large Used primarily in customized.

Can be one-time use, reloadable, manual, or Linear Stapler: Creates a Linear Cutter: Creates a linear Circular Cutter: Performs Clips: Used in the ligation electronically powered. linear staple line; no cutting cut and immediately staples circular cut and staple. Used of vessels, may be metal or function. Used in ligation and both free edges. Used in in reanastomosis of hollow absorbable material. Open Staples come in anastomosis.
