Background
The main purpose of artificial joint replacement is to relieve joint pain, correct deformity, and restore and improve joint movement. The hip joint is the largest weight-bearing joint of the human body. Smooth cartilage surfaces of the hip joint are not innervated and normally move very flexibly without pain. When the articular cartilage is severely damaged, subchondral bone is exposed, and secondary abrasion, hardening and hyperplasia form osteophytes. Subchondral bones are nervous, and have rough surfaces, and the subchondral bones are rubbed with each other to generate continuous and severe pain and swelling, which are further aggravated along with the progress of the disease, and the movement is limited. Eventually, various non-surgical methods fail and hip replacement is required.
The hip joint replacement is also called artificial hip joint replacement, and is a relatively mature and reliable treatment means by fixing an artificial prosthesis comprising a femur part and an acetabulum part on normal bone by bone cement and screws so as to replace a diseased joint and reconstruct the normal function of the hip joint of a patient.
In hip joint replacement, for example, when a femoral stem is driven into, femur cleavage occurs or after hip joint replacement, a part of patients are fractured around a femoral side prosthesis due to trauma, and when hip joint revision operation is needed, the femur needs to be tied and fixed by steel wires. The phenomenon of slipping and loosening of the bundled steel wires is frequently found in the operation and the follow-up visit after the operation. The reason is that the thickness of the femoral shaft is variable, and the steel wire easily slides from a thick place to a thin place. In addition, when the binding of the steel wires is finished and knotted, the steel wires are easy to loosen; in order to firmly fix the steel wire and avoid sliding, the device is designed to ensure long-time effective fixation.

Detailed Description
The technical scheme of the invention is described in detail below with reference to the accompanying drawings.
Examples
The present embodiment provides a steel wire tightening anti-slip device, as shown in fig. 1 to 3, including: the base 1 is provided with a base top surface 11 and a base bottom surface 12 which are oppositely arranged, and an anti-skid structure is arranged on the base bottom surface 12; the top cover 2 is provided with a top cover top surface 21 and a top cover bottom surface 22 which are oppositely arranged, and a steel wire limiting structure is arranged on the top cover top surface 21; and a supporting member 3 which connects the base 1 and the top cover 2, makes the top cover bottom surface 22 opposite to the base top surface 11, and can drive the top cover 2 to move towards or away from the base 1.
When the wire tightening anti-skid device is used, the wire for bundling the femur passes through the wire limiting structure, after bundling is finished and knotted, the external force is used for driving the stretching piece 3, the top cover 2 is driven to move towards the direction away from the base 1, the top cover 2 is outwards stretched, and the wire is further tensioned, so that the wire is fastened on the femur; after the steel wires are tightened, the tightening force of the steel wires enables the anti-skid structure arranged on the bottom surface 12 of the base to be tightly combined with the femur surface, so that the base 1 is firmly positioned and fixed at a certain position of the femur; the base 1 firmly fixed further positions the steel wires through the steel wire limiting structure arranged on the top cover 2, and plays a role in preventing the steel wires from sliding. After the steel wire tightening anti-skid device of the embodiment is used, the steel wire fixing force is large, loosening and sliding can not occur, and the operation effect is good.
