Abstract

The invention discloses a 3D printed individual femoral neck osteotomy guide plate. The osteotomy guide plate comprises a femoral neck attachment part, a guide column and a cutting guide surface, wherein the femoral neck attachment part is suitable to ride across femoral neck, and the lower surface of the femoral neck attachment part is attached to the surface of the femoral neck; the guide columnis arranged on the upper surface of the femoral neck attachment part, is suitable to drive a kirschner wire so as to fix the osteotomy guide plate on the femoral neck; the front side surface of the femoral neck attachment part vertically extends upward to form the cutting guide surface, the cutting guide surface is attached to a saw blade so that the saw blade can cut the femoral neck downwards along the cutting guide surface. The osteotomy guide plate is applied to an artificial hip replacement surgery, can improve accuracy of osteotomy operation and accurately control osteotomy height and direction so as to improve accuracy of femoral stem prosthesis placement positions and contribute control of length of double lower limbs, and the surgery effect of the artificial joint replacement surgery is improved.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a 3D printed individualized femoral neck osteotomy guide plate. Background technique

[0002] At present, in total hip arthroplasty, the femoral neck osteotomy operation mainly relies on the experience of the surgeon. The position 10-15 mm above the lesser trochanter is selected for visual positioning and manual osteotomy, and the accuracy is poor. Due to the different levels of surgical experience of the surgeons, there is a large difference in the position of the osteotomy, which affects the position and direction of the femoral prosthesis. Complications such as unequal length of lower limbs, lameness, loosening and sinking of the prosthesis reduce the service life of the prosthesis and seriously affect the quality of life of the patient. At present, the femoral osteotomy template for total hip replacement uses the lesser trochanter, greater trochanter, and medial femo...
