Multifunctional drilling device for skull defect model

Abstract

The invention relates to a skull defect model multifunctional drilling device which comprises an operation box, a fixing plate and a mounting seat, sliding rods inserted into the side wall of the operation box are arranged at the two ends of the mounting seat, vertical sliding grooves allowing the sliding rods to move are formed in the side wall of the operation box, a lead screw is arranged in each vertical sliding groove, and a screw rod is arranged in each lead screw. A lead screw nut matched with the lead screw is arranged at the top end of the sliding rod, the lead screw is connected with a lifting motor arranged in the operation box, a drilling device is arranged on the installation base and comprises a drill bit base, a drill rod and a drill bit arranged at the top end of the drill rod, and a clutch groove and an insertion groove are formed in the drill bit base. When the rat skull is drilled, the drill bit can be automatically controlled to stop rotating after drilling is finished, drilling is prevented from being too deep or too shallow, and the building success rate of a skull defect model is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of animal experimental instruments, in particular to a multifunctional drilling device for a skull defect model. Background technique: [0002] At present, due to osteoporosis, pathological fractures, traumatic fractures and many other diseases, there is a need to promote osteogenesis and inhibit osteoclasts. Therefore, there are more and more experimental studies on osteogenesis. In these osteogenesis-related experiments , the recognized animal model is the rat or rabbit skull defect model, which is often modeled in SD rats by using a diamond drill to drill a large hole above the SD rat skull, and then perform corresponding interventions to observe bone regeneration In this kind of modeling process, the following problems are often prone to cause modeling failure: 1. During the drilling process of the diamond drill, there is a large amount of shaking, and the experimenter is prone to shaking hands during o...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multifunctional drilling device for a skull defect model, which solves the problem that the prior art cannot accurately control the depth of the skull drilling, which easily leads to too deep or too shallow drilling depth, which affects the establishment of the experimental model.
