AI Technical Summary

Technical Problem

Existing laparoscopic anastomosis instruments have poor sealing devices, which are prone to air leakage and can cause secondary injury to patients during insertion.

Method used

A sealing device comprising a protective sleeve, a sealing panel, and an airbag was designed. The airbag surrounds the outside of the protective sleeve, and the airbag is automatically inflated and deflated by an elastic piston. The sealing panel is stably fixed at the patient's incision site by interlocking with the protective sleeve.

Benefits of technology

It improves sealing, avoids air leakage, reduces the expansion damage to the patient's incision, and simplifies the insertion process.
