Technical Field

[0001] This utility model relates to the field of medical cutting tools, and in particular to a wear-resistant and fracture-resistant medical cutting tool clamping device. Background Technology

[0002] Surgical power systems are indispensable key equipment in modern surgery, with extremely wide applications in numerous surgical fields. They provide a stable and precise power source for various medical instruments, enabling surgeons to more easily perform operations such as tissue cutting, grinding, and drilling, greatly improving the accuracy, efficiency, and safety of surgery. The surgical handpiece is a crucial component of the surgical power system, and its instrument clamping device is vital to surgical quality.

[0003] Existing tool clamping devices typically have a clamping head integrated into the motor's power shaft. This allows the motor to provide operating power to the tool while also clamping it. However, different medical procedures require different tool specifications. Therefore, it is necessary to quickly disassemble and install the tool. Furthermore, the transverse cutting force during the rotational cutting process causes significant stress on the clamping point, which can lead to breakage. Utility Model Content
