Abstract
The invention relates to a compression hip-screw guider inserted through skin, and belongs to the technical field of medical apparatus. The compression hip-screw guider comprises a grip, a femur abutting rod and a guide pipe. One end of the femur abutting rod is fixedly connected with the grip, and the other end of the femur abutting rod is a sharp end. A universal screw hole is arranged on the top portion of the femur abutting rod. One threaded end of the guide pipe is fixedly connected with the universal screw hole. When the compression hip-screw guider is used for implementing a compression hip screw implantation, a hip screw is inserted from skin by the aid of the sharp end of the femur abutting rod, then the guide pipe is inserted to be positioned by being fixedly connected with the universal screw hole through threads, and finally the compression hip screw is inserted into the guide pipe to complete the compression hip screw implantation. A surgical incision of the process is extremely minor; minimally invasive surgery can be realized; patient's healing time is shortened; implantation direction and angle of the hip screw can be adjusted; and the hip screw can be positioned precisely. The compression hip-screw guider is simple in overall structure, low in cost, and wide in application.
