AI Technical Summary

Technical Problem

The clamp arms of existing clampers can wear the coating during multiple openings or closings, and even lead to perforation of the coating, causing the metal surface to be exposed again, reducing the safety of the clampers.

Method used

A tissue clamping device is designed, using a clamping member and an elastic inner clamping arm. The clamping member is wrapped with an outer membrane and a local inner membrane is arranged on the inner side of the outer membrane to avoid the rotation end of the clamping part being directly in contact with the outer membrane during opening or closing, reducing wear, and maintaining the flexible rotation of the clamping part.

Benefits of technology

It effectively avoids the wear of the outer membrane during rotation of the clamping part, improves the safety and reliability of the device, and reduces the cost of coating and the difficulty of wear-proofing process.
