Anchoring positioning device and video-assisted thoracic surgery system guided by electromagnetic navigation

Abstract

The present invention discloses an anchoring positioning device and a video-assisted thoracic surgery system guided by electromagnetic navigation. The anchoring positioning device comprises a positioning lead and a sensing plug, and the positioning lead comprises an anchoring head, a sensing probe and a conduit tube; and the anchoring head and the sensing probe are arranged in the conduit tube, the anchoring head can be anchored on lesions, and the sensing probe can detect a current position coordinate. Therefore, in a surgery process, when the positioning lead goes deep into the lesions, position prompt information of the sensing probe can accurately judge whether the lesions are reached, and after the lesions are reached, the anchoring head can be anchored on the lesions, so that the far, deep and small lesions can be effectively positioned.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an anchor positioning device and a TV-assisted thoracoscopic surgery system guided by electromagnetic navigation. Background technique [0002] During video-assisted thoracic surgery (VATS) surgery, the localization of lesions is a major difficulty. The current positioning methods and positioning equipment are: 1. Hook-wile positioning under the guidance of computed tomography (CT), but this technology has the risk and possibility of decoupling during the positioning process, especially for 10mm or less 2. Melan and other staining and marking methods, but melanin is easy to spread, and the location of the lesion cannot be seen clearly if the operation time is too long; 3. Use an ultrasound probe for positioning, but because the lungs are mostly air, the range of ultrasound detection is limited , it cannot play a very good role in the localization of lesions in deeper positions....

Problems solved by technology

The current positioning methods and positioning equipment are: 1. Hook-wile positioning under the guidance of computed tomography (CT), but this technology has the risk and possibility of decoupling during the positioning process, especially for 10mm or less 2. Melan and other staining and marking methods, but melanin is easy to spread, and the location of the lesion cannot be seen clearly if the operation time is too long; 3. Use an ultrasound probe for positioning, but because the lungs are mostly air, the range of ultrasound detection is limited , can not play a very good role in the localization of deep lesions

[0003] Therefore, the existing positioning methods and positioning equipment have the problem of being unable to effectively locate far, deep, and small lesions
