Abstract

The invention relates to a punching device, and especially relates to an orthopedic surgery positioning punching device. The technical problem of the present invention is to provide an orthopaedic surgical positioning and punching device which can stably punch a drill bit, stably adjust a drilling angle, and has a support device capable of alleviating pain. A technical scheme: an orthopedic surgical position punching device comprise a base, a tail, a first bearing seat, an upper L-shaped cylindrical rod, a first limit block, a compression spring, a sleeve, a plug, a second bearing seat, a first pinion, etc. A tail seat is arrange on that right side of the base, a first bearing seat is arrange on the upper part of the tail seat, and an upper L-shaped cylindrical rod is arranged in the firstbearing seat. As that plug block is arrange, the plug block contacts with the first pinion gear when people do not use the equipment, so that the first pinion gear can be prevented from move at willon the semi-ring gear, and as the toggle bar is arranged, the sleeve can be driven to move by rotating the toggle bar, so that the equipment can carry out subsequent work and is convenient for peopleto operate.

Description

technical field [0001] The invention relates to a punching device, in particular to a positioning punching device for orthopedic surgery. Background technique [0002] Bone drilling is a common procedure in orthopedic surgery. It is necessary to drill the bone before screwing the bolt or steel plate into the patient's leg. At present, people mainly use the drill to drill the patient's bone. When using the drill, It is difficult for the doctor to accurately control the angle of the drill bit, and it is easy to cause deviation to affect the operation; in order to control the angle of the drill bit without deviation, the doctor usually needs to use the guide to guide at the same time, and it is troublesome for the doctor to control the drill while controlling the guide. , is not conducive to surgery; when people are performing drilling surgery, there is no corresponding equipment for auxiliary support, which makes the patient feel more pain. Contents of the invention [0003...
