This utility model discloses a minimally invasive surgical shaving head, relating to the field of medical device technology. To address the problems of easy clogging of the shaving tube during the removal of diseased tissue and the increased risk of accidental injury during pressure cutting in existing technologies, the following technical solution is proposed: This utility model includes an inner shaving seat, an outer shaving seat, an outer shaving tube, an inner shaving tube, a cutting window, and a cutting edge. A cutting window is provided on the side of the end of the outer shaving tube, consisting of two waist-shaped holes arranged in an "X" shape. The outer shaving seat is fixedly located at the end of the outer shaving tube away from the cutting window. The inner shaving tube is located inside the outer shaving tube, and a cutting edge is provided at the position corresponding to the cutting window on the inner shaving tube. The inner shaving seat is fixedly located on the inner shaving tube away from the cutting edge. This utility model, through the cooperation of the "X"-shaped cutting window and the inclined blade, uses a segmented cutting stroke to preferentially aspirate the cut tissue fragments under continuous negative pressure, effectively avoiding the problem of excessive accumulation of loose tissue in the inner shaving tube cavity, thus preventing clogging.

This invention discloses a gear cutting machine tool with a measuring tool function, relating to the field of gear cutting technology. The invention includes a cutting table, a gantry frame mounted on top of the cutting table, a laser cutting assembly installed on the inner top of the gantry frame, a lifting cylinder mounted on top of the gantry frame, and a cutting module fixedly mounted at the bottom of the telescopic end of the lifting cylinder. A bottom mold is fixedly mounted at the bottom of the mounting shaft, and several adjustable molds are provided on the top of the bottom mold. Both the bottom mold and the adjustable molds have cooling chambers located at the gear teeth. This invention adopts an integrated mold shielding and cooling design, which can prevent accidental cutting, provide a measuring tool for the gear, and, based on the high heat flow density at the tooth tip and root, set cooling channels in corresponding areas to achieve precise thermal management. It integrates cutting guidance and active cooling into the same mold, resulting in a compact structure and multifunctional design.
