The electronic mirror sheath is fixedly installed on the grinding head mounting cylinder, and at least the position of the electronic mirror sheath corresponding to the electronic endoscope lens part is closely attached to the surface of the grinding head mounting cylinder, so that the heat generated during the grinding and shaving work of the grinding action part is transferred to the electronic mirror sheath through heat conduction, and has a heating and defogging effect on the electronic endoscope lens installed in the electronic mirror sheath.

[0005] Further, the electronic endoscope lens part in the electronic mirror sheath corresponds to the front end port of the electronic mirror sheath, and the front end of the electronic mirror sheath is closely attached to the surface of the grinding head mounting cylinder.

[0006] Further, the front end of the electronic mirror sheath is flush with the opening end of the grinding head mounting cylinder.

[0007] Further, the distance between the tip of the grinding action part and the opening end of the grinding head mounting cylinder is 5 - 8 mm.

[0008] Further, the central axes of the grinding head rod and the electronic mirror sheath are parallel to each other.

[0009] Further, it further includes a water outlet pipe, and the water outlet pipe is fixedly connected to the surface of the grinding head mounting cylinder and is parallel to the electronic mirror sheath.

[0010] Further, the front ends of the electronic mirror sheath, the water outlet pipe and the opening end of the grinding head mounting cylinder are flush with each other.

[0011] Further, the electronic mirror sheath and the water outlet pipe are seamlessly connected to the grinding head mounting cylinder by laser welding.

[0012] Further, a plurality of micropores for dispersing water flow to reduce the water outlet impact force are provided on the peripheral wall at the end of the water outlet pipe.

[0013] Further, the micropores are uniformly distributed in a ring along the peripheral wall at the end of the water outlet pipe.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] In the visible surgical power handle of the present invention, by closely attaching the position of the electronic lens sheath corresponding to the electronic endoscope lens part to the surface of the grinding head mounting cylinder, the heat generated during the grinding operation of the grinding part is conducted through the grinding head rod adapted to be installed in the grinding head mounting cylinder to the surface of the grinding head mounting cylinder and then transmitted to the electronic lens sheath, thereby heating and defogging the electronic endoscope lens in the electronic lens sheath, effectively improving the clarity of the surgical field of view, and ensuring the accuracy of surgical operations.
