Description

technical field [0001] The invention relates to the technical field of pelvic tunnel screw placement or pelvic acetabular external fixator needle placement, in particular to a novel multifunctional anchorable pelvic screw placement guide. Background technique [0002] The technology of pelvic tunnel screw and external fixator is an important part of the first aid for pelvic fractures and the minimally invasive treatment of pelvic acetabular fractures. The fast and accurate placement of pelvic tunnel screws and external fixator needles is the key to ensure the success of the operation. For the convenience of surgeons Insertion of screws. At present, some manufacturers have designed soft tissue protection sleeves with handles that can be inserted into hollow screws or external fixator needles. However, there are still some shortcomings in the soft tissue protection sleeves with handles on the market, such as: [0003] 1. The handle of this type of sleeve is too short, and the ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a new type of multifunctional anchorable pelvic screw insertion guide to solve the problem that the traditional sleeve handles on the market are too short, and the grasping hands and handles cover the intraoperative perspective. Field of view, the hand is directly exposed to the central part of the fluoroscopy, so that the operator absorbs more radiation, and the sleeve is easy to slide on the bone surface, which affects the screw insertion and cannot guide the insertion of the external fixator needle
