Certified Surgical Technologist (CST) Practice Exam

Which of the following is used by the surgeon to intermittently remove prostatic tissue fragments during a TURP?

1. Wire snare

2. Ellik evacuator

3. Poole suction

4. Randall forceps

The correct answer is: Ellik evacuator

The Ellik evacuator is specifically designed for the intermittent removal of tissue during procedures like transurethral resection of the prostate (TURP). During TURP, prostatic tissue is resected, and the surgeon needs a reliable method to evacuate the tissue fragments from the surgical site to maintain visibility and clear the operative field. The Ellik evacuator allows for effective suctioning of these fragments while minimizing trauma to surrounding tissues. This instrument works by creating negative pressure to suck out the tissue bits without allowing for excessive bleeding or fluid absorption, which is crucial during such delicate procedures. It also typically has a larger collection chamber, making it suitable for handling the volume of tissue that may be excised during a TURP. Other instruments listed may have their specific uses but do not serve the same purpose in the context of a TURP. For instance, while a wire snare is used for cutting or grasping tissue, it does not actively evacuate tissue fragments. Poole suction is designed more for removing fluid and debris rather than solid tissue, and Randall forceps are primarily used for grasping or handling stones during urological procedures rather than for the evacuation of tissue during TURP. Therefore, the Ellik evacuator is the most
