By means of the embodiments of the present application, assistance can be quickly and accurately provided during surgery.

This invention relates to a patient positioner and, more specifically, to an articulated armature configured to position a leg and knee at a precise angle, as needed in unicompartmental knee arthroplasty surgery. The positioner is adapted to connect to either side rail of a support table, without changing orientation, via drop pins disposed in a socket clamp. The socket clamp may couple to a ball coupled to a first arm and elbow joint, which in turn may couple to a second arm and wrist joint, which in turn may couple to a pad assembly adapted to hold the patient's thigh, thereby positioning the lower leg to dangle over the side or end of an operating table. The positioner is adapted for ease of disassembly, sterilization, and reassembly. The invention may be exchanged for a total knee replacement positioner without moving the patient or breaking the sterile field.

The invention provides a unicondylar replacement guiding and positioning equipment design method and related equipment. The design method comprises the following steps: acquiring historical medical data of a unicondylar osteotomy object; generating a knee joint statistical morphology model based on the historical medical data; and generating a predetermined unicompartmental knee arthroplasty guiding and positioning device based on the knee joint statistical morphology model. According to the method, the knee joint statistical morphology model is generated through the historical medical data, and then the unicompartmental knee arthroplasty guiding and positioning equipment is generated based on the statistical morphology model, so that the generated unicompartmental knee arthroplasty guiding and positioning equipment is matched with an individual, and the osteotomy precision and the operation effect of unicompartmental knee arthroplasty are improved.

The invention provides a preoperative planning method and device for unicompartmental knee arthroplasty. The method comprises the steps that a preoperative medical image of any object is acquired; constructing a three-dimensional skeleton model of the knee joint based on the preoperative medical image; and based on the three-dimensional skeleton model, determining a preoperative planning scheme of unicompartmental knee arthroplasty. According to the preoperative planning method, the size and the position of the implanted prosthesis can be determined before the operation, and whether the prosthesis meets the performance requirement or not can be virtually tested, so that joint surface reconstruction and prosthesis position determination are optimized.

The utility model belongs to the technical field of medical instruments, and particularly relates to a knee joint inner side unicompartmental knee replacement prosthesis center line measurer. The utility model provides a knee joint inner side single condyle replacement prosthesis midline measurer, and aims to solve the problem that in the prior art, a femur inner side condyle midline is not provided with a measuring tool, so that the determination error of the femur condyle midline is large. A knee joint inner side unicondylar replacement prosthesis center line measurer comprises a main board and a positioning block arranged at one end of the main board, the main board is further provided with an auxiliary measuring board, and the auxiliary measuring board is arranged at the end, close to the positioning block, of the main board; according to the utility model, the positioning groove on the positioning block is contacted with the surface of the thighbone inner side condyle, and the center line auxiliary line is arranged in the positioning groove, so that a doctor can visually see and determine the position of the center line of the thighbone inner side condyle. By means of the design, errors caused by manual judgment or tool limitation in a traditional method are avoided, and the measurement accuracy is improved.

The invention provides a cold region orthopedics department digital intelligence diagnosis and treatment intelligent operation planning system comprising a total knee joint replacement planning module used for planning according to an acquired knee joint medical image and cold region specificity data; the total hip replacement planning module is used for planning according to the acquired hip joint medical image and cold region specificity data; the unicondylar joint replacement planning module is used for planning according to the obtained knee joint medical image and cold region specificity data; the acetabulum periphery osteotomy planning module is used for planning according to the obtained hip joint medical image and cold region specificity data; the sports medical planning module is used for planning according to the acquired joint medical image and cold region specificity data; the spine planning module is used for planning according to the spine medical image and the cold region specificity data; and the trauma planning module is used for performing trauma operation planning according to the trauma part medical image and the cold region specificity data.

This invention provides an automated osteotomy planning method and system for unicompartmental knee arthroplasty, comprising: acquiring a first contact point between the femur and tibia on the healthy side of the knee joint, and a second contact point between the femoral prosthesis and tibial prosthesis on the surgical side of the knee joint; generating the postoperative motion trajectory of the femur and tibia based on the first and second contact points; and automatically planning the amount of osteotomy of the femur or tibia on the surgical side of the knee joint based on the motion trajectory of the femur and tibia. This invention solves the problems of traditional manual surgery relying on the surgeon's experience, affecting the surgical outcome, and currently lacking effective intraoperative planning and accurate prediction capabilities. It greatly improves the safety and efficiency of unicompartmental knee arthroplasty, while also improving the surgical outcome, and significantly enhances the intelligence, usability, and reliability of this invention.
