Abstract

The invention relates to the technical field of medical instruments, and provides a bone drill bit and a base mounting method. The bone drill bit comprises a positioning assembly and a milling assembly; the positioning assembly comprises a positioning boss, and the positioning boss is used for being arranged in a mounting hole formed in the bone in advance; the milling assembly comprises a millingknife edge and a clamping part, the clamping part is connected with the milling knife edge, and the milling knife edge is connected with the positioning boss; the clamping part is used for being connected with an external power device and driving the milling knife edge to rotate under the action of the external power device; and the bone drill bit can mill an installation surface around the installation hole, the shape of the installation surface is matched with the shape of the bottom surface of a DBS base, the installation surface can be completely attached to the bottom surface of the DBSbase, and the fixing effect is better. In the fixing process, the DBS base does not deform, subsequent fixing of an electrode locking device is facilitated, and then the stability of the DBS electrodewire can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, relates to a bone drill bit and a base installation method. Background technique [0002] Deep Brain Stimulation (Deep Brain Stimulation, abbreviated as DBS), also known as brain pacemaker surgery, has developed into an alternative to the traditional brain stereotaxic functional surgery in the past 20 years. . DBS technology is to implant electrodes in specific nerve nuclei in the brain through brain stereotaxic technology, inhibit abnormal neurons and their fibers through high-frequency electrical stimulation, reduce the state of excessive neuronal excitation in patients, and make the inner environment of the nerves tend to be more stable. Normal, stable, and then achieve the purpose of treating diseases. [0003] At present, the DBS electrode lead is fixed on the base by stimloc (electrode locking device), and the base is fixed on the surface of the skull. ...
