AI Technical Summary

Technical Problem

Existing electrosurgical devices cannot precisely control the cutting direction during gastrointestinal endoscopic surgery. The blade must be manually cleaned after it adheres to tissue. The water injection function is limited and remote operation is not possible, resulting in low surgical efficiency.

Method used

It adopts a master-slave control system, replacing manual control with an electric drive unit. Combined with the joint structure and multi-chamber design, it achieves precise motion control of the electric cutting knife and adjustment of water volume, and is equipped with a real-time cleaning function.

Benefits of technology

It improves the precision and efficiency of electrosurgical excision procedures, ensures smooth surgical procedures, reduces reliance on physician experience, and enhances the automation and efficiency of the surgery.
