AI Technical Summary

Technical Problem

The existing ultrasonic scalpel has insufficient degrees of freedom, resulting in poor operational flexibility and difficulty in adapting to complex surgical environments.

Method used

Design a multi-degree-of-freedom ultrasonic scalpel that integrates a suspension-type transmission system with a gear motor, bending gear, rotary motor, and transmission line to achieve multi-directional movement of the scalpel head, including rotation, bending, and opening/closing actions. The ultrasonic transducer generates high-frequency vibrations for cutting and solidification.

Benefits of technology

It improves the operational flexibility of the ultrasonic scalpel and its ability to adapt to complex surgical environments, thereby enhancing surgical efficiency, ease of operation, and precision.
