Three-dimensional digital magnifier operation supporting system

Abstract

Provided is a system for displaying indirect influence of the variations of the state of the imaged space and the state of the displayed three-dimensional computer graphics images fixed to and combined with a subject by simulation of the variation of the state of the subject in a real space on the three-dimensional computer graphics. From among surface polygon models (2) made by three-dimensionally measuring a subject image present in the same space, a surface polygon model having a shape similar to the surface polygon model (1) is discriminated and detected by shape pattern recognition. A computer graphics picture is tracked. A computer graphics image reflecting the variation of the real relative positions is displayed superimposedly on the captured image in accordance with the variation of the relative position of the subject with respect to the imaging device occurring in the real three-dimensional space. With this, a combined image position complement tracking system for displaying the subject in the field of view of the imaging device and the virtual three-dimensional computer graphics image in such a way that the subject and the virtual three-dimensional computer graphics images are viewed integrally.

Description

technical field [0001] The present invention relates to a medical navigation system that displays the positional relationship between the patient's position and operating surgical instruments in order to improve safety and reliability when surgery is approaching invisible areas in minimally invasive surgery. Surgical support system. More specifically, the present invention relates to a three-dimensional digital magnifier surgery support system, which superimposes and displays the three-dimensional computer image of the invisible area or shape of the entity (patient's body and surgical instruments) that is stereoscopically recognized by the three-dimensional digital magnifier , so as to integrate the physical image and the virtual three-dimensional computer image and make a three-dimensional recognition. Background technique [0002] In the past, when approaching invisible areas in surgery, two-dimensional or three-dimensional image data formed on the basis of non-destructiv...

Problems solved by technology

This kind of detailed human three-dimensional perception will improve with accumulated experience and proficiency. However, the correctness of non-blood observation processing can only be evaluated through the three-dimensional image data after surgery.

In addition, if blood observation surgery is used to perform surgery in the body with poor vision, if you lose your direction, you will go in the wrong direction, which will inevitably cause unnecessary tissue damage.
