Universal guider for minimally invasive surgery of femoral neck fracture and application thereof

Abstract

The invention relates to the field of medical instruments, in particular to a universal guider for minimally invasive surgery of femoral neck fracture and an application thereof. The guider comprises a first aiming mechanism, a connecting rod and a second aiming mechanism which are connected in sequence, and at least one set of kirschner wire fixing holes are formed in the first aiming mechanism; a plurality of groups of kirschner wire guide holes are formed in the second aiming mechanism, and the second aiming mechanism is rotationally connected with the connecting rod so as to change the direction of the second aiming mechanism relative to the connecting rod. The guider disclosed by the invention can be stably and reliably anchored on greater trochanter of femur, so that an operator can see through outside an operating room, radiation is avoided, and the guider is relatively safe.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a universal guide for minimally invasive surgery on femoral neck fractures and its application. Background technique [0002] At present, when performing minimally invasive surgery for femoral neck fractures, the operator usually wears radiation-proof equipment, uses X-ray equipment to see through the affected part of the patient, and holds a Kirschner wire sleeve to determine the position and direction of the needle through fluoroscopy, and then uses an electric drill. Drive the Kirschner wire into the affected area along the direction of the hand-held sleeve; if the position is not good, pull out the Kirschner wire, readjust the position, and use the electric drill to drive the Kirschner wire in again, repeat several times until the position is good, and drill into the hollow Screws, the operation is over. [0003] In order to improve efficiency, a positioner and a guide with a ...

AI Technical Summary

Problems solved by technology

[0005] When performing the above-mentioned operations, patients and doctors need to undergo multiple fluoroscopy and will be subjected to multiple radiations, causing certain physical injuries; meanwhile, the existing Kirschner wire sleeves or locators are held and fixed during use, and when the Kirschner wires are implanted It is easy to shake and shift during the insertion process, which will cause poor position, which will not only increase the difficulty and accuracy of Kirschner wire implantation, but also repeatedly insert and pull out the Kirschner wire during the repeated position adjustment process, which will damage the patient's bone, prone to iatrogenic fractures
