High tibial biplane osteotomy navigation guide plate

Abstract

An embodiment of the invention discloses a high tibial biplane osteotomy navigation guide plate. The guide plate comprises an upper split guide plate and a lower split guide plate which are fixedly connected by two connecting rods. An osteotomy guide groove is formed between the upper split guide plate and the lower split guide plate. Two non-parallel kirschner wire fixing guide holes are formed in the middles of the upper split guide plate and the lower split guide plate. Parallel guide holes are formed in the upper part of the upper split guide plate. One side of the upper split guide plateis provided with an angle guide backup plate. The upper split guide plate and the lower split guide plate are respectively provided with an upper angle positioning rod and a lower angle positioning rod in a vertical corresponding mode, and the end portions are respectively connected with an upper angle positioning guide hole and a lower angle positioning guide hole. The guide plate can not only eliminate the difference between experiences of doctors in a surgery, but also greatly reduce the operation time and the amount of bleeding during the surgery to achieve the best ideal state of osteotomy. The recovery time of a patient is greatly reduced, postoperative complications are reduced, and expenses in the recovery period are saved.

Description

technical field [0001] The invention relates to an auxiliary medical device for osteotomy, in particular to a navigation guide plate for high tibia biplane osteotomy. Background technique [0002] Medial tibial high biplane osteotomy (OWHTO) is a kind of incomplete osteotomy, and the lateral 10mm bony hinge is preserved during osteotomy. The biplane osteotomy is divided into a horizontal osteotomy plane and an ascending osteotomy plane. The structure is more stable. The ascending osteotomy plane is located in the cancellous bone area with rich blood supply, and the healing is faster. The approach of OWHTO is located on the medial side of the proximal tibial plateau, from the level of the joint line to the upper border of the goose foot, there are no important muscles, blood vessels and nerves along the line, and the exposed position is small, and the lateral osteotomy hinge is located at the proximal end of the upper tibiofibular articular surface , so OWHTO only performs a...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the embodiment of the present invention is that in the traditional operation process of tibial osteotomy, in order to ensure the short healing time of the patient's incision, the intraoperative field of view is not large enough, and it is necessary to determine the angle and depth by Kirschner wire The secondary fluoroscopy ensures that the operation requirements are met, so the operation time is very long, and the patient has a large amount of blood loss, which will increase the occurrence of complications. A navigation guide for high tibial biplane osteotomy is proposed.
