Problems solved by technology

[0005] In order to solve the problem that the existing artificial knee prosthesis technology cannot preserve the patient's healthy anterior cruciate ligament or even if the anterior cruciate ligament is preserved, the anchoring area between the prosthesis and the tibia is reduced and the operation is difficult. An artificial knee replacement prosthesis that retains or reconstructs the anterior cruciate ligament and retains a large anchoring area and is convenient for operation

Embodiment Construction

[0034] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] figure 2 and image 3It is a preferred embodiment of the liner 20, one of the components of the artificial knee replacement prosthesis of the present invention. Here, the passage through which the liner accommodates the anterior cruciate ligament is a gap, and the gap is arranged in the center of the liner 20. At the rear, the notch is U-shaped or horseshoe-shaped, and the two extended parts of the U-shaped structure are working bodies. The upper surface of each working body is provided with a spherical concave surface 21 for accommodating the femoral condyle, and the lower surface of the working body is provided with a fastening boss 24. Mates to form a fixed connection. The edge of the U-shaped notch portion 22 of the gasket 20 is provided with a horizontal raised edge 23, preferably a U-shaped edge along the periphery of the U-...

Abstract

The invention discloses an artificial knee joint replacing prosthesis capable of reserving and rebuilding anterior cruciate ligament, in order to solve the problems that the existing artificial knee joint prosthesis technology can not reserve the healthy anterior cruciate ligament of the patient, or that even if reserving the anterior cruciate ligament, the anchoring area of the prosthesis and the tibiae part is reduced and the operation is difficult. The artificial knee joint replacing prosthesis comprises a tibiae platform holding part and a liner, the tibiae platform holding part comprises a horizontal stand and a fixed connection structure fixedly connecting the horizontal stand and the tibiae, the liner also has a channel for anterior cruciate ligament to pass through, the tibiae platform holding part is provided with a pore passage for penetrating upper and lower surfaces of the horizontal stand of the tibiae platform holding part, the size of the pore passage can be suitable for the imbedded anterior cruciate ligament and adhesive bone block thereof to pass through; the artificial knee joint replacing prosthesis also comprises an anti-disengage structure preventing the imbedded bone block from disengaging. The artificial knee joint replacing prosthesis of the invention not only can reserve or rebuild the anterior cruciate ligament, but also can reserve the large anchoring area, simultaneously the surgery operations is convenient.

Description

technical field [0001] The invention belongs to artificial joint prosthesis technology, in particular to a novel artificial knee joint prosthesis technology. Background technique [0002] Artificial joints are one of the most important advances in the field of orthopedics in the 20th century. It enables patients who used to rely on crutches to walk, or even amputated, to walk like normal people, greatly improving the quality of life. As a mature treatment method, it has been widely used at home and abroad. At present, artificial joint replacement has become the ultimate treatment for severe bone and joint diseases, and is known as an important milestone in the development history of orthopedics in the 20th century. [0003] The development of total knee replacement (TKR) surgery has also achieved great success. However, all current knee prosthesis designs cannot achieve the same function as the normal knee joint, and the knee joint is different from the normal knee joint in...
