Abstract

The invention discloses a medical drilling device. With application of the medical drilling device of the technical scheme, by arranging a main shell, a drill bit and a limiting part, the drill bit is movably arranged in the main shell in the axial direction; the limiting part is adjustably arranged on the main shell and limits the drill bit at a preset position when the drill bit moves to the preset position in the axial direction, so that the medical drilling device can accurately limit the drilling depth of the drill bit to prevent the drill bit from damaging brain nervous tissues of a patient when drilling a hole in a brain of the patient in the interventional therapy process, and the problem that the drilling depth of the adopted drill bit cannot be grasped when department of cerebral surgery carries out interventional therapy on the patient in the prior art is solved.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a medical drilling device. Background technique [0002] When performing interventional treatment in the brain surgery of the hospital, it is necessary to drill holes in the patient's brain to open up a treatment channel for the interventional treatment, so that the drug can be delivered directly to the affected area. At present, when drilling a patient's brain, the manual drill used cannot grasp the drilling depth, and the drilling is performed entirely on the doctor's experience. In the process, the drill often drills too deep and damages the patient's brain nerves. organizational issues. Contents of the invention [0003] The main purpose of the present invention is to provide a medical drilling device to at least solve the problem in the prior art that the drill bit used in brain surgery for interventional treatment of patients cannot grasp the drilling depth. [0004] I...
