AI Technical Summary

Technical Problem

The existing vascular clamps are difficult to monitor the stress of blood vessels, cannot record experimental data, and it is difficult to quickly replace the clamp head, which affects the experimental efficiency and cannot accurately observe the vascular condition.

Method used

A clamper is designed including a clamping device, a monitoring device and an observation device. The clamping device attaches a clamping arm and a clamping head through a screw lock. The monitoring device monitors the blood vessels in real time through a force sensor and a display screen. The observation device drives the amplifier to approach or away from the clamping head through an electric push rod to achieve removable replacement and accurate observation.

Benefits of technology

Real-time monitoring and display of vascular stress values is realized, and the rapid replacement of clamping heads is improved, which improves the accuracy and efficiency of experimental operations and facilitates the operation of experimenters.
