Pelvic bone tumor osteotomy guide plate

Abstract

The invention relates to the field of medical devices, in particular to a pelvic bone tumor osteotomy guide plate and a construction method thereof. The invention provides a construction method of a pelvic bone tumor osteotomy guide plate model, comprising the following steps: obtaining a pelvic skeleton three-dimensional model and an osteotomy line; obtaining a cutting bonding surface of the guide plate; constructing a guide plate ontology model based on the cutting and bonding of the guide plate extending outward; constructing a first circuitous part model; constructing the second circuitouspart model; constructing a reinforcement model; constructing a fixed arm model; and constructing the nail path model on the guide plate ontology model. The pelvic bone tumor osteotomy guide plate provided by the invention can facilitate the surgeon to perform osteotomy according to the preoperative plan during the operation, can achieve personalized treatment for each patient, accurate and rapidremoval of tumor entities, and to the maximum extent, can avoid damage to the surrounding normal tissue structure, improve the accuracy of the operation, reduce the operation time, and facilitate therecovery of patients after surgery.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pelvic bone tumor osteotomy guide plate and a construction method thereof. Background technique [0002] The pelvic bone is an irregular bone with many bony anatomies; pelvic bone tumors are divided into type I: ilium; type II: acetabulum; type III: obturator area; type IV: sacrum according to the different pelvic bone structures involved. Refractory pelvic tumors are good indications for osteotomy guide plates due to their highly individualized shape and location. The personalized osteotomy guide plate can guide the surgeon to perform osteotomy according to the preoperative plan during the operation, accurately and quickly remove the tumor entity, and avoid damage to the surrounding normal tissue structure to the greatest extent. However, limited by the materials used, the osteotomy guide plate is often not a rigid structure, and the deformation of the guide plate during the op...

AI Technical Summary

Problems solved by technology

However, limited by the materials used, the osteotomy guide plate is often not a rigid structure, and the deformation of the guide plate during the operation will directly affect the accuracy of the operation result.

In addition, the preoperative planned location often lacks a clear and unique bony landmark, and the instability of the osteotomy guide plate in the intraoperative position will cause the direction of the osteotomy position to deviate from the optimal spatial position in the plan, resulting in surgical errors, and patients cannot obtain surgical results. Desirable post-operative results in pre-plan

The above problems will make it impossible to accurately transfer the preoperative plan to the actual operation, so the optimal surgical plan cannot play a role
