The application relates to the technical field of surgical assistance, and discloses a foot deformity correction surgery planning and implementation method, which comprises the following steps: fusing multi-modal medical images and dynamic function data to construct a high-fidelity foot digital twin model; intelligently quantitatively evaluating and mechanismally analyzing deformities by using a deep learning network combined with a knowledge graph; automatically optimizing in a virtual space by using a multi-agent reinforcement learning algorithm to generate a personalized surgery plan verified by biomechanical simulation; converting the optimized scheme into augmented reality navigation information and robot control instructions to guide a surgical robot to perform adaptive and accurate osteotomy and reduction operations; dynamically evaluating execution deviations and guiding correction by using real-time three-dimensional scanning and registration technology during the operation, and intelligently matching and implanting internal fixators; immediately performing function verification after the operation, and generating a personalized digital rehabilitation scheme and long-term curative effect prediction for the patient based on the operation result. The application constructs an intelligent surgery ecological system throughout the whole process of "diagnosis, planning, implementation, evaluation and management", and significantly improves the accuracy, safety, predictability and scientific level of curative effect management of foot deformity correction surgery.

The present application relates to a kind of metatarsophalangeal joint replacement prosthesis for hallux valgus patient, it is related to medical instrument technical field, it includes toe bone prosthesis, metatarsal bone prosthesis and the toe bone platform pad between them;The handle body surface of metatarsal bone prosthesis and toe bone prosthesis is provided with serrated structure;Metatarsal bone prosthesis is close to toe bone end and is equipped with limiting groove, and toe bone platform pad is close to metatarsal end and is equipped with limiting lug, limiting lug is embedded in limiting groove to form hinged connection structure, so that joint activity is constrained to single sagittal plane.The present application fills the clinical blank of severe hallux valgus metatarsophalangeal joint replacement prosthesis, through stable hinged structure, lengthened serrated intramedullary canal handle and multi-angle adaptation design, while realizing deformity correction and long-term stability, joint activity is retained.
