Computer simulation scaling biopsy method and apparatus

Abstract

The invention discloses a method which can carry out follow-up tracing and virtual endoscopy to a gastroscope probe in gastroscopy process to implement analogue scaling biopsy on the focus in the stomach and provides a device for computer analogue scaling biopsy; the device comprises a main control module and a three-dimensional space locator used for acquiring spatial location and orientating information of the gastroscope probe, wherein, the main control module comprises a three-dimensional surface model module of an inner gastric wall, a three-dimensional space locating module of the gastroscope probe, a follow-up tracing module, a virtual endoscopy module and an analogue scaling biopsy module. The method can help to carry out callback and follow-up examination to stomach diseases, can realize noninvasive analogue scaling biopsy of stomach focus and can support doctors to make completely non-invasive focus image analysis in vitro.

Description

technical field [0001] The invention relates to a tracking and virtual endoscopic technology of a gastroscope probe, in particular to a computer simulation calibration biopsy method and a device for realizing the method. Background technique [0002] There are 870,000 new cases of gastric cancer each year, accounting for 9.9% of all cancers. The standardized incidence and mortality rate of gastric cancer in my country ranks second among malignant tumors. Monitoring of precancerous lesions and intervening to block their development to gastric cancer will significantly reduce the incidence and mortality of gastric cancer. Regular monitoring of gastric precancerous lesions can make the detection rate of early gastric cancer more than 50%, and the 10-year survival rate can reach more than 90%. Some routine diseases of the stomach, such as ulcers, are also common diseases with a high incidence rate. At present, the monitoring of gastric precancerous lesions mainly uses ordinar...

AI Technical Summary

Problems solved by technology

[0004] Although MTB technology can solve the problem of the accuracy of pathological tissue collection and the effectiveness of judging the effectiveness of interventional blocking therapy in the monitoring of gastric precancerous lesions, the operation of this technology is somewhat difficult, and it is more cumbersome than ordinary biopsy forceps. It can only be calibrated and biopsy cannot Treatment of complications during biopsy, such as bleeding, etc., can not be used for local treatment of precancerous lesions, and the injection of calibrator also has the possibility of local trauma
