Skull drill

Abstract

The invention belongs to the technical field of medical instruments, and concretely relates to a skull drill. The skull drill comprises a guide rail, two ends of the guide rail are rotationally connected with rotating shafts, one ends, away from the guide rail, of the two rotating shafts are rotationally connected with first sliding blocks, the bottom ends of the first sliding blocks are movably connected with a sliding rail, a second sliding block is movably connected to the top of the guide rail, a first sleeve is fixed on the sidewall of the second sliding block, a push rod motor is fixed to the top end of the first sleeve, an electric drill is movably installed on the inner sidewall of the first sleeve, and the output shaft of the push rod motor is fixed to the top end of the electricdrill. The drilling depth of a drill bit is controlled through accurate stroke control of the push rod motor and auxiliary inspection of a pressure sensor, so the situation that contrary dura mater and brain tissue of a patient are injured by drilling due to failed control of the drilling depth during manual drilling is avoided, and therefore the success rate of an operation is increased.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a skull drill. Background technique [0002] The skull sits above the spine and consists of 23 flat and irregular bones of various shapes and sizes. Except for the mandible and hyoid bone, the rest of the bones are firmly connected to each other by sutures or cartilage, which play a role in protecting and supporting the brain, sensory organs, and the initial parts of the digestive and respiratory organs. [0003] In the course of neurosurgery, it often involves the operation of drilling at the bone edge of the skull. For example, for cases where the dura mater needs to be suspended, such as after hematoma removal or tumor resection, it is necessary to drill holes at the bone edge of the skull to suspend the dura mater. At the edge of the bone; for cases where the temporalis muscle needs to be confirmed, such as temporalis muscle sticking, it is necessary to drill a h...

Problems solved by technology

[0004] The traditional neurosurgery operation is manual operation to apply an electric ball mill drill to the target part of the skull, and then flush water to cool down; due to the large error of manual operation, and the thickness of each person's skull is different, especially the thickness of a child's skull is thin, and the drill The depth of the hole cannot be accurately grasped, and the electric ball mill drill is prone to damage the dura mater and brain tissue. Accordingly, the present invention proposes a skull drill
