Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to an orthopedic positioning and error-eliminating oscillating saw. Background Art

[0002] Total knee replacement is an effective method for treating end-stage knee osteoarthritis. Before installing the prosthesis, osteotomy is required on the femoral and tibial sides to remove bone, so that the patient's bone surface fits the shape of the prosthesis, and then the prosthesis is installed on the osteotomized bone surface. During bone osteotomy, it is necessary to determine the position and angle of the bone surface osteotomy. Generally, an oscillating saw is used for osteotomy. The common way for an oscillating saw to drive the saw blade is through a fork rod eccentrically mounted on an output shaft driven by a motor. The output shaft rotates to drive the fork rod to continuously hit the fork to drive the fork to swing left and right. The fork drives the vibration shaft to swing and thus realizes the oscillating osteotomy movement of the oscillating saw blade. During the osteotomy process, an osteotomy guide plate can be used in conjunction with the oscillating saw. The osteotomy guide plate device is installed on the patient, and the saw blade of the oscillating saw passes through the positioning groove on the osteotomy guide plate device to perform osteotomy on the bone surface. However, the installation of the osteotomy guide plate device requires a large number of positioning tools for coordinated application. At the same time, the gap between the osteotomy guide plate and the saw blade is large, and the accuracy deviation of osteotomy is also relatively large. At the same time, the osteotomy guide plate positioning tool is poorly adaptable to patients and cannot be adapted to various patient conditions. In addition, the oscillating saw will generate swinging force during use, and the gripping accuracy is poor, which will also reduce the accuracy of osteotomy. Summary of the invention
