CIS - Certified Instrument Specialist Surgical Instrument Identification Questions and Answers

Question 1

A surgeon requests a clamp to atraumatically grasp the intestine. Which of the following instruments would be the most appropriate choice?

Accepted Answer

Babcock clamp

Answer

Babcock clamps are designed with fenestrated, smooth, and rounded tips, making them ideal for grasping delicate tissues like the intestines or fallopian tubes without causing trauma. Allis clamps have serrated teeth and are used for grasping tougher tissue that may be removed. Kocher clamps have strong teeth and are for grasping heavy, tough tissues like fascia. Foerster sponge forceps are used for holding surgical sponges.

Question 2

Which of the following scissors is specifically designed for cutting heavy tissues such as fascia and muscle?

Accepted Answer

Mayo scissors

Answer

Mayo scissors are heavier and more robust than other dissecting scissors, making them suitable for cutting tough tissues like fascia, muscle, and sutures. Metzenbaum scissors are longer and more delicate, used for dissecting soft tissues. Iris and Tenotomy scissors are very fine and used for delicate procedures, such as ophthalmic surgery or precise tissue dissection.

Question 3

During a procedure, a self-retaining retractor is needed to hold a small, superficial incision open. Which of the following would be the most suitable choice?

Accepted Answer

Weitlaner retractor

Answer

A Weitlaner is a self-retaining retractor with sharp or blunt prongs, commonly used in basic plastic surgery, large bone and joint procedures, and to hold open small to medium-sized incisions. A Balfour is a large self-retaining retractor used for deep abdominal procedures. A Deaver and an Army-Navy are handheld retractors, not self-retaining.

Question 4

What is the primary distinguishing feature between a Kelly hemostat and a Crile hemostat?

Accepted Answer

The extent of the serrations on the jaws

Answer

The key difference between a Kelly and a Crile hemostat is the serrations on their jaws. Crile hemostats have serrations that run the entire length of the jaw. Kelly hemostats have serrations that only extend partially, typically halfway, down the jaw. Both come in similar sizes and can be straight or curved.

Question 5

A surgical technician is assembling a tray for a delicate vascular procedure. Which type of tissue forceps would be most appropriate for handling fine blood vessels?

Accepted Answer

DeBakey forceps

Answer

DeBakey forceps have multiple, fine, atraumatic serrations and are specifically designed for delicate and cardiovascular procedures to handle fine tissues like blood vessels with minimal damage. Adson forceps with teeth are for grasping skin. Russian forceps have a rounded, toothed tip for grasping dense tissue. Bonney forceps are heavy forceps used for grasping fascia.
