AI Technical Summary

Technical Problem

The pressure resistance of existing circumcision staplers is difficult to quantify and assess, which makes the anastomosis prone to failure under postoperative physiological pressure, potentially leading to serious medical risks such as anastomosis rupture, bleeding, and fistula formation.

Method used

A pressure resistance tester for circumcision staplers was designed, comprising an internal pressure sealing test system, an external pressure environment simulation system, and a bidirectional pressurization test system. Through precise air pressure control and multi-point pressure application, physiological and external pressure environments are simulated to evaluate the pressure resistance performance of the anastomosis.

Benefits of technology

It enables precise pressure testing of the anastomosis, ensuring the stability and reliability of the testing process. It can identify minute leaks and rupture pressure thresholds, reducing the risk of postoperative complications and improving surgical safety.
