AI Technical Summary

Technical Problem

Existing vascular closure systems have a high failure rate in treating calcified vessels, struggle to identify minute structures, and have limited adaptability to changes in tissue thickness, leading to an increased risk of postoperative rebleeding.

Method used

Design a surgical device for vascular closure with intelligent temperature control, including a clamping head module, a sensing module, and an energy output module. The device monitors the vascular status in real time through temperature sensors, voltage sensors, current sensors, and distance sensors. The control module dynamically adjusts the energy output based on the data to achieve segmented temperature control and adaptive closure.

Benefits of technology

It improves the stability and efficiency of vascular closure, reduces the risk of thermal damage and closure failure, adapts to different tissue thicknesses and calcified vessels, and reduces the possibility of postoperative rebleeding.
