Abstract

The embodiment of the invention discloses a method and device for detecting and locating a lesion in video-assisted thoracoscopy surgery. The method includes the steps that a locating wire with a locating sensor and an extension catheter together enter the area where the lesion is located; the location information of the lesion is detected through the locating sensor of the locating wire; the anchoring position of an anchoring tong is determined according to the length of the locating wire entering, and the extension catheter is fixed and supported at the anchoring position (the lesion position) through the anchoring tong; after a lung collapses in the process of surgery, the locating wire is controlled through the extension catheter to enter the lesion portion again, and the lesion is located through the locating sensor of the locating wire and an external detector used for detecting the position and the direction of the locating sensor. The method can locate the lesion location in real time, the location is more efficient and more accurate, and the problem of the difficulty in locating the lesion in VATS is solved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for detecting and locating lesions in video-assisted thoracoscopic surgery. Background technique [0002] During video-assisted thoracic surgery (VATS) surgery, for currently common smaller, softer, deeper, intersegmental fissure, multiple, invisible, and intangible lesions, the lung collapses during the operation It is difficult to achieve intraoperative real-time localization of small lesions in the lung. [0003] The current existing solutions are not ideal, and it is difficult to achieve real-time intraoperative precise positioning. Preoperative positioning includes: transthoracic or transbronchopulmonary puncture methylene blue injection (diffusion), placement of microcoils (displacement), hook wire positioning (shedding), and radiotracer injection (radiation). Intraoperative positioning includes: intraoperative thoracoscopic B-ultrasound probe positio...
