AI Technical Summary

Technical Problem

In existing technologies, the main vein cannot be completely closed after treating varicose veins, resulting in unsatisfactory treatment outcomes.

Method used

A varicose vein ligation device was designed, including an operating handle, a clamping component, and an adjustment structure. Under ultrasound guidance, the clamping component is inserted into the periphery of the main vein. The adjustment structure drives the clamping component to switch between open and clamping positions, thereby achieving clear ligation of the main vein.

Benefits of technology

It achieves precise closure of the main venous trunk, improves treatment outcomes, and reduces trauma and recovery time by employing a minimally invasive surgical approach.
