AI Technical Summary

Technical Problem

In remote retinal surgery, the surgeon's lack of force perception makes it impossible to accurately control the force applied to the eye tissue by the surgical instruments, which may cause damage to the eye tissue, such as retinal tears or bleeding.

Method used

A surgical forceps with force protection function was designed, including a fixation bracket assembly, a drive assembly, a working catheter, a forceps assembly, a buffer assembly, and a clutch assembly. Excessive force is buffered by a permanent magnet, and the clutch assembly controls the movement of the forceps assembly to achieve clamping, rotation, and pulling actions, simplifying the structure.

Benefits of technology

It effectively prevents the forceps components from being subjected to excessive force due to misoperation, avoids excessive displacement that could cause patient injury, and improves the safety and precision of the surgery.
