Abstract

A laparoscopy bag of a flexible material with traction strings of drawstrings is provided at its opening or mouth, in particular for use in a trocar, and in which the bag consists of a working section to which a hose-shaped part or extension is attached or which is provided with a hose-shaped extension.

Claims

1. A method of excising tissue from an abdominal cavity, comprising the steps of:

(a) inserting through an abdominal wall a trocar having an internal diameter and communicating with an abdominal cavity;

(b) introducing into said abdominal cavity in a collapsed state a laparoscopy bag, said laparoscopy bag being composed of flexible material and consisting essentially of;

a relatively large diameter working section having a circular cross section and an open mouth and adapted to receive resected tissue and instruments for dissecting resected tissue in said working section,

a hose-shaped extension closed at a free end and connected with said working section centrally opposite said mouth and extending away from said working section, said hose-shaped extension being of a smaller diameter than said mouth and so dimensioned that said hose-shaped extension, when filled with resected tissue, can be withdrawn from said cavity through said trocar,

a tapered, funnel-shaped portion connecting said working section with said extension, and

drawstrings at said mouth for closing same prior to withdrawal of said bag through said trocar;

(c) opening said bag within said cavity;

(d) resecting tissue within said abdominal cavity;

(e) introducing resected tissue into said bag through said mouth in said cavity;

(f) drawing said mouth closed with said drawstrings;

(g) drawing the bag against the trocar to squeeze the bag and force resected tissue from the working section of the bag into the hose-shaped extension; and

(h) pulling said bag with said hose-shaped extension filled with resected tissue out of said cavity through said trocar with said drawstrings.
