AI Technical Summary

Technical Problem

During endoscopic submucosal dissection (ESD), auxiliary traction devices are difficult to continuously provide effective traction, resulting in limited visual field, residual lesion or incomplete resection.

Method used

A tissue traction device is designed, including a traction device, which consists of a first connector, a second connector and a constant force traction member. The constant force traction element provides constant traction through a constant force spring, meeting preset conditions to ensure continuous traction of the lesion site during ESD surgery.

Benefits of technology

By providing constant and stable traction, tissue traction devices ensure the normal progress of ESD surgery, avoiding the problems of field of vision and lesion residues, and improving the success rate and accuracy of the surgery.
