However, this structure causes the upper part of the shell to be larger, which increases the overall weight of the craniotomy drill. At the same time, after a long time of use, the tightening screw becomes loose, and the motor will slide out of the receiving cavity, which may easily cause accidents during surgery.

Abstract

The invention discloses a craniotomy drill, comprising a host machine, a speed reducer and a locking base which are in threaded connection in turn; a drill transmission rod connected with the output shaft of the speed reducer is inserted in the locking base; the craniotomy drill is characterized in that the host machine comprises a handle (1) at the lower side and a containing part (2) at the upper side; containing part (2) is internally provided with a stator having a DC motor and a rotor (5); and the wall (4) of the containing part (2) is the outer housing of the DC motor stator. The craniotomy drill has simple structure, and the wall of the containing part is directly used as the outer housing of the motor stator, thereby reducing the volume and reducing the entire weight. The craniotomy drill can prevent the motor from being slid off and can have comparatively high safety performance. Simultaneously, the craniotomy drill has integrated design and comparatively excellent waterproofperformance because of waterproof material and technique.

Description

technical field [0001] The invention relates to a bone drill motor used in surgical operations. Background technique [0002] In surgery, the craniotomy drill is a more commonly used craniotomy tool. The craniotomy drill includes a host, a reducer, a locking seat and a drill bit, and the host includes a housing with a handle at the bottom, a cylindrical housing at the top, and a cylindrical motor. When assembling, it is necessary to plug the motor into the cavity of the cylindrical housing on the upper part of the housing, and then fix the motor with the tightening screws. However, this structure causes the upper part of the shell to be larger, which increases the overall weight of the craniotomy drill. At the same time, after a long time of use, the tightening screw becomes loose, and the motor will slide out of the receiving cavity, which may easily cause accidents during surgery. . Contents of the invention [0003] The purpose of the present invention is to provide ...
