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

[0036] As shown in Figures 5 and 6, another component of the artificial knee joint replacement prosthesis of the present invention is the tibial platform holder, which includes a horizontal platform 30 and a connecting column 33 provided on the lower surface of the horizontal platform. The upper surface of the horizontal platform 30 is provided with 2 A fastening recess 32 is arranged corresponding to the fastening boss 24, and the cooperation of the two makes the pad 20 fasten on the horizontal platform 30 of the platform support and fix the pad 20. A rectangular hole 31 is provided between the two fastening recesses 32 in the middle of the horizontal platform 30 of the tibial plate support. 3. To match the attachment site of the anterior cruciate ligament on the tibia. The tunnel 31 can also be in other shapes. The function of the tunnel 31 is to allow the anterior cruciate ligament and the attached bone fragments to pass through. The shape of the tunnel 31 should be basica...

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 comprisesa 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...
