Technical Field
The invention relates to the technical field of medical instruments, in particular to an adjustable medial and lateral malleolus positioning module for a tibial high-position osteotomy surgical guide plate.
Background
With the aging of Chinese population and the improvement of economic level of people, more and more knee osteoarthritis patients are required to be treated due to pain and limited activity, and the quality of life is improved. Knee replacement has become well established as a surgical procedure and therapeutic regimen with precise results. However, knee joint replacement has the disadvantages of large trauma, limited service life of prosthesis, infection, loss of proprioception and the like. High-order osteotomy of shin bone (HTO) is regarded as and intervenes a "knee protection" treatment of medial knee osteoarthritis, receive more and more people's welcome, HTO has the advantage of correcting lower limb force line, relieve pain, delay articular cartilage further destruction etc., traditional high-order osteotomy of shin bone needs to rely on the abundant clinical experience of art person and intraoperative repeated perspective, but often can't reach the anticipated effect planned before the art because of patient's personalized difference, with the development of computer and 3D printing technique, it can increase its accuracy, simplicity etc. to apply HTO to treat knee osteoarthritis to the supplementary to 3D printing technique, thus reach ideal curative effect.
The adjustable medial and lateral malleolus positioning module is connected with the guide frame by clamping the medial and lateral malleolus of a patient, so that repeated fluoroscopy and repeated osteotomy in an operation are avoided, the operation time is shortened, the operation accuracy and simplicity of an operator are improved, and a satisfactory clinical curative effect is obtained.
