A method for automatic planning of surgical path

Abstract

The invention discloses a method for automatic planning of a universal surgical path. The method is aimed at surgical operations. Through the 3D reconstruction model of the patient's medical image, the generalized cavity space for surgical instrument activities is defined. A plan to find the best path from the body surface; this method can quickly integrate the surgical experience of high-capacity medical centers through the intraoperative generalized cavity space database, and establish a widely applicable preoperative intelligent, automated, and individualized surgical path planning plan ; In the generalized cavity space, the strategy of reverse searching the surgical path for all possible skin access positions can automatically plan the feasible surgical path with the shortest path, minimal trauma, good surgical field exposure, and avoiding important functional areas, so as to achieve its Universal, suitable for automatic path planning of various operations, comprehensively and three-dimensionally improve the medical level and medical information level.

Description

technical field [0001] The invention belongs to the field of intelligent path simulation planning for surgical operations, and in particular relates to a universal automatic surgical path planning method. Background technique [0002] Traditional surgical path planning is based on doctors' rich clinical experience, on the basis of familiarity with human anatomy and medical image data, abstracting the relative relationship between lesions and surrounding tissues, and then determining specific surgical plans. This method relies heavily on the knowledge and experience of doctors, causing a huge workload for surgeons. At the same time, differences in surgical experience also lead to differences in the quality of surgical path planning for doctors with different seniority, which limits the sinking of medical technology and the utilization of medical resources. balance. [0003] With the development of computer-aided surgical planning and the era of big data, the way of surgical ...

AI Technical Summary

Problems solved by technology

[0010] However, it can be seen that so far, the successful computer-aided automatic surgical path planning methods are only suitable for simple applications, such as intervention with a fixed linear treatment path, ablation therapy, etc., and with a relatively fixed cavity intracranial and skeletal

For more extensive flexible cavity organ tissue surgery, due to the complexity of anatomical structures and the diversity of patient conditions, there is no computer-aided and fully automatic surgical path planning method at present.
