A tension bend steel plate used for patella fracture

Abstract

The invention relates to a tension bend steel plate used for patella fracture. The tension bend steel plate comprises a transverse fixing plate and two longitudinal tension plates connected to the two ends of the transverse fixing plate; the tension plates tilt toward the outer sides gradually from one end close to the transverse fixing plate to the end away from the transverse fixing plate; the two longitudinal tension plates and the transverse fixing plate are arranged in a pi-shaped manner; upper and lower pole screws penetrate the transverse fixing plate; the longitudinal tension plates are provided with fixing screws. The tension bend steel plate used for patella fracture is simple in operation and good in firmness, is not liable to breakage and easy to take out, and saves surgery time; the tension bend steel plate used for patella fracture can replace traditional Kirschner wire tension bands or hollow screw tension bands and become a medical product specialized in patella fracture, having a wide application prospect in clinical promotion.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tension band steel plate for patella fracture. Background technique [0002] The patella is the largest sub-bone of the human body, located in front of the knee joint, and has the function of protecting the knee joint. The articular surface behind the patella is opposite the trochlear surface of the femur. The quadriceps muscle is attached to the upper edge of the patella, and part of the fascia continues through the front of the patella to form the patellar ligament and inserts on the tibial tuberosity. The patella plays a vital role in the movement of the human knee. For example, as an intermediate structure of the knee extension device, it transmits the pulling force generated by the quadriceps muscle to the patellar tendon; the patella acts as a lever when extending the knee, which can effectively Increase the leverage arm of the knee extension device to the flexi...

AI Technical Summary

Problems solved by technology

This method has the following deficiencies and defects: 1. In order to realize the effect of longitudinal compression of the hollow screw, the hollow screw needs to be placed in parallel, which is difficult to operate and requires experienced surgeons to complete; 2. The tension band of the hollow screw is through the steel wire The wound is fixed in front of the patella in a crossed "8" shape, and the cutting of the ligament by the steel wire will block the blood supply, which will have a negative impact on the healing of the fracture; 3. The mechanical environment between the hollow screw and the eight-shaped wound steel wire is complex , it is not easy to take out, and during the activity, the steel wire is easy to break at the reflexion

And there is no report about this tension band steel plate
