Problems solved by technology

Osteotomy position, osteotomy angle, and size of osteotomy are often only measured and marked by two-dimensional imaging images, and the osteotomy operation is performed with the experience of doctors during the operation. The operation effect is not good, and even the operation fails.
If the osteotomy is inappropriate and the re-osteotomy often fails to achieve the ideal anatomical alignment, the operation time will be prolonged, and the poor alignment will affect the postoperative healing of the osteotomy

Abstract

The invention provides a method for manufacturing personalized orthopedic positioning guide plates. The method includes designing the personalized orthopedic positioning guide plates according to three-dimensional models of areas of interest of patients and then manufacturing the personalized orthopedic positioning guide plates by the aid of 3D (three-dimensional) printing technologies. The method has the advantages that doctors can carry out bone cutting operation under the guidance of straight slots of the orthopedic positioning guide plates and can carry out orthopedic operation under the guidance of positioning holes of the orthopedic positioning guide plates, accordingly, the surgical difficulty can be lowered owing to the orthopedic positioning guide plates, and the surgical safety can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a manufacturing method of a personalized orthopedic positioning guide plate. Background technique [0002] Osteotomy orthopedic surgery can not only improve the appearance of deformities, but more importantly, prevent and treat osteoarthritis caused by severe deformities. At present, in clinical orthopedic surgery, there is often a lack of quantitative tools for osteotomy and correction. Osteotomy position, osteotomy angle, and size of osteotomy are often only measured and marked by two-dimensional imaging images, and the osteotomy operation is performed with the experience of doctors during the operation. The operation effect is not good, and even the operation fails. Inappropriate osteotomy and re-osteotomy often fail to achieve the ideal anatomical alignment. The operation time is prolonged, and poor alignment will affect the postoperative healing of the osteotomy. ...
