Purse suturing device for hollow viscus

A purse suturing device for a hollow viscus, such as the oesophagus or rectum, is a specialised surgical stapler used to prepare tissue for an anastomosis (the joining of two body structures).

This device is particularly useful in areas where hand-sewn suturing is difficult or impossible, such as during laparoscopic or pelvic surgery.Key components and features of the device include:Circular Stapler: Comprises a tubular stapler head, a handle with an actuator, and an anvil.

Dual-Position System:Pursing Position: The anvil is retracted from the stapler head, creating space for a suturing thread to be wound around the viscus.Stapling Position: The anvil moves close to the stapler head, compressing and folding the tissue layers together.Suturing Thread: Typically a plastic monofilament like polypropylene, which is wound around the tissue and tightened against the anvil's pole to create a pursed fold.

Pushing Stick: An optional tool used to fasten the thread tightly around the pole without needing to tie a knot.Staple Carrier: Includes a series of projections and recesses that hold the staples and provide space for the pushing stick to operate.This device improves surgical outcomes by providing a more secure and better-vascularised edge for subsequent procedures compared to traditional linear staplers, which can sometimes leave portions of the suture outside the target area.
