Laparoscopic procedures to create pneumoperitoneum
Show Solution
The Correct Option isA
Solution and Explanation
Name the gadget: a slim cone-shaped applicator carrying a tiny stretched silastic band is the Falope ring (Yoon ring) applicator, and its single job is female sterilisation by tubal occlusion.
Mechanism in one line: pull a knuckle of tube into the cone, slip the contracting silastic ring over its base, and the strangled loop loses its lumen, the tube is blocked.
Knock out the wrong uses: an ectopic pregnancy is removed by salpingostomy or salpingectomy, not by this ring. Termination of pregnancy uses suction evacuation or medical abortifacients, again unrelated. Pneumoperitoneum at the start of laparoscopy is created with a Veress needle (or open Hasson entry), which looks nothing like a ring applicator. So the instrument's only role here is laparoscopic sterilisation.
