Image-guided lung interventional operation system

Abstract

The invention discloses an image-guided lung interventional operation system which comprises an image acquiring module, a lung region reconstruction module, a lung respiratory movement model construction module, an operative instrument and operative region image space mapping module, a dynamic focus space-positioning and guide module and an another image acquiring module. The image acquiring module is connected with the lung region reconstruction module which is connected with the lung respiratory movement model construction module, the lung respiratory movement model construction module is connected with the dynamic focus space-positioning and guide module, and the another image acquiring module is connected with the operative instrument and operative region image space-mapping module which is connected with the dynamic focus space-positioning and guide module. Real-time space positioning of dynamic focuses is achieved, early diagnosis of carcinogenesis of lung nodule can be achieved, and error of space positioning precision is within 2mm.

Description

technical field [0001] The invention relates to a system in the technical field of medical equipment, in particular to an image-guided pulmonary interventional operation system. Background technique [0002] Percutaneous lung biopsy is the preferred method for the diagnosis of small nodules in peripheral lung cancer. Interventional navigation with the help of image information will greatly improve the accuracy and safety. There are generally two types of percutaneous lung puncture based on image navigation technology: conventional CT guidance and CT perspective guidance. [0003] These two methods have achieved the purpose of three-dimensional display to a certain extent. The interventional doctor can observe the actual position of the surgical instrument by referring to the three-dimensional image displayed on the computer monitor, and guide the minimally invasive intervention process. However, these two techniques have their own limitations. Both conventional CT guidance ...

Problems solved by technology

[0007] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides an image-guided pulmonary intervention system. This system integrates the pulmonary respiratory motion model taking into account the movement of the trachea and blood vessels into the three-dimensional positioning technology, and performs dynamic lesions and surgical instruments. Real-time spatial positioning and navigation to overcome the mismatch between static CT information and dynamic internal organ locations, especially small lesions, in existing CT-guided percutaneous lung biopsy
