Surgical guide plate for high tibial osteotomy

Abstract

The invention relates to the technical field of medical equipment, and in particular to a surgical guide plate for high tibial osteotomy. The surgical guide plate comprises a proximal tibia fixation module, a guide plate connecting rod, and a medial and lateral malleolus positioning module, wherein the proximal tibia fixation module is fixedly installed at the top of the guide plate connecting rod, and the medial and lateral malleolus positioning module is fixedly installed at the bottom of the guide plate connecting rod. The instrument provided by the invention has the advantages such as short surgical time, accurate positioning of an osteotomy position, less number of intraoperative X-ray exposures, short surgical incision, and small soft tissue trauma.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a surgical guide plate for high tibial osteotomy. Background technique [0002] With the aging of China's population and the improvement of people's economic level, more and more patients with knee osteoarthritis require treatment due to pain and limited mobility to improve their quality of life. Knee arthroplasty has become a mature operation and a curative treatment plan that has been recognized by everyone. However, knee arthroplasty has disadvantages such as large trauma, limited service life of the prosthesis, infection, and loss of proprioception. High tibial osteotomy (HTO), as a "knee-preserving" therapy for medial knee osteoarthritis, has been welcomed by more and more people. HTO can correct the alignment of the lower limbs, relieve pain, and delay further destruction of articular cartilage, etc. Advantages, the traditional high tibial osteotomy needs to rely ...

AI Technical Summary

Problems solved by technology

However, there are disadvantages such as large trauma, limited service life of the prosthesis, infection, and loss of proprioception in knee arthroplasty.

High tibial osteotomy (HTO), as a "knee-preserving" therapy for medial knee osteoarthritis, has been welcomed by more and more people. HTO can correct the alignment of the lower limbs, relieve pain, and delay further destruction of articular cartilage, etc. Advantages, the traditional high tibial osteotomy needs to rely on the operator's rich clinical experience and repeated intraoperative fluoroscopy, but often due to the individual differences of patients, the expected effect of preoperative planning cannot be achieved. With the development of computer and 3D printing technology, Applying 3D printing technology to assist HTO in the treatment of knee arthritis can increase its accuracy, simplicity, etc., so as to achieve ideal curative effect

[0003] At present, high tibial osteotomy mainly depends on the operator's experience to determine the osteotomy position, and X-rays are taken many times during the operation to adjust and confirm the correction angle of the force line, resulting in long operation time, low operation accuracy and damage to the health of the operator.
