Description
Technical Field
The invention relates to the technical field of surgical instruments, in particular to a knee joint revision file.
Background
In recent years, cases of knee joint revision have increased significantly. The obvious reason is that along with rapid development of social economy and continuous improvement of technological level, the requirements of people on life quality are higher and higher, so that the number of total knee joint replacement operations is remarkably increased, and the total knee joint replacement fails due to abrasion, infection, aseptic loosening and the like along with the lapse of time, and the knee joint function needs to be reconstructed through knee joint revision; in addition, patients who undergo total knee replacement surgery are younger and younger, and patients gradually undergo total knee replacement surgery (TKA) in hopes of meeting the requirement of high activity through TKA surgery, so that total knee replacement surgery cannot meet the requirement of the old age; furthermore, there is a considerable factor-the weight of the patient, and the excessive weight will cause the prosthesis to bear too high pressure, which causes the knee prosthesis to have larger wear and even damage within the service life, so that the knee revision surgery is required, which is especially obvious in western countries, and KurtzS et al predicts that the amplitude of the knee revision surgery in the united states will greatly exceed the initial total knee replacement/initial total hip replacement/hip revision surgery.
Based on the above, optimizing the steps of the knee joint revision surgery, reducing the cost of the revision surgery, and increasing the post-operative stability are important research subjects in the field of joint replacement surgery.
The basic process of the knee joint revision surgery is as follows: firstly, taking out the knee joint prosthesis subjected to primary replacement, then, adjusting the distal femur end and the proximal tibia end, opening holes at the distal femur end and the proximal tibia end, and finally, implanting the femoral revision prosthesis and the tibial revision prosthesis; in the process, the conventional hole opening mode and the fixing mode of the prosthesis mainly comprise the steps of reaming spongy bones in tibia and femur by using a reamer, placing the prosthesis in the hole opening and compacting the hole opening, or coating bone cement for fixing, or inserting a special-shaped structure in a medullary cavity to prevent the prosthesis from rotating relative to bone. However, this approach has certain drawbacks: after the operation of the existing surgical tool, the matching degree of the shape of the reaming hole after the osteotomy and the actually implanted revision prosthesis is low, so that the difference of the implantation height or the stability between the reaming hole and the actually implanted revision prosthesis possibly occurs due to the difference of the bones of the patient, and certain risks exist for the success rate of the revision surgery and even the rehabilitation of the patient.
On this background, the present invention provides a knee joint revision file to solve the drawbacks of the prior art.
