Oral and maxillofacial space infection incision and drainage virtual training method

Abstract

The invention relates to an oral and maxillofacial space infection incision and drainage virtual training method and is used for knowing an anatomical part of space infection and selecting a correct incision and drainage part through the method. The method comprises the following steps of 1) establishing a skull three-dimensional model, and inputting the skull three-dimensional model into a computer simulation device; 2) inputting a muscle module used for simulating muscle, adding the muscle module to the three-dimensional model, adding an abscess module outside the mandibular ascending branchfor the clearance of the occlusal muscle, and covering the cheekbone zygomatic arch and the mandibular ascending branch mandibular angle area with the occlusal muscle on the abscess so as to determine the anatomical part of the clearance abscess of the occlusal muscle; (3) inputting an instrument module used for simulating the surgical knife so as to select the surgical knife and the incision part, and after incision, enabling vessel forceps to extend into a gap along the exterior of the mandible, and (4) selecting and operating the instrument module after abscess drainage. The method is advantaged in that the method operability is strong, and the method can be widely applied to the technical field of medical science.

Description

technical field

[0001] The invention relates to the field of medical technology, in particular to a virtual training method for incision and drainage of oral and maxillofacial space infection. Background technique

[0002] Due to the many surgical operation items and complicated content of "Oral and Maxillofacial Surgery", the training items carried out in the school are single, which is out of touch with clinical operation. Many practical training projects cannot be carried out, so we purchased a virtual simulation training system. The product is an oral simulation training equipment based on computer graphics technology, which can visually simulate the three-dimensional environment of the oral cavity, and at the same time simulate the left and right hand operation handles of real oral tools. The force feedback function of operating habits; it has oral surgery graphics and force feedback development interface, and can simultaneously provide four digital simulation subsystem...
