Video-assisted thoracoscope locating and marking method and device

Abstract

The embodiment of the invention provides a video-assisted thoracoscope locating and marking method, which comprises the following steps of: obtaining locating information which includes the locating information of lesion; determining a preoperative locating mode according to the locating information; locating the lesion according to the preoperative locating mode, and obtaining the locating information of the lesion; carrying out a real-time calibration by combining with ultrasonic technique during the operation to obtain marking information; and resecting the lesion according to the locatinginformation and marking information of the lesion. By the adoption of the video-assisted thoracoscope locating and marking method, different preoperative locating methods are provided, meanwhile, theultrasonic three-dimensional real-time calibration technique is adopted during the operation to obtain the locating information of the lesion and the marking information related to the lesion, so thatthe lesion is accurately located and a definite surgical excision edge is provided at the same time, thereby avoiding unnecessary excision of the lesion, and overcoming the problem that an existing locating and marking method cannot accurately locate and mark small lesions, which leads to large excision range.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for positioning and marking a video-assisted thoracoscope. Background technique [0002] With the improvement of people's awareness of early lung cancer screening and the continuous updating of medical examination methods, more and more isolated lung lesions have been detected, including those with a diameter of ≤3cm that are opaque and completely surrounded by lung tissue of lesions. [0003] At present, video-assisted thoracic surgery (VATS) is the first choice for suspicious lung cancer nodules, which has the advantages of less trauma and faster postoperative recovery, but surgeons often cannot accurately locate the lesion during surgery for small pulmonary nodules , had to take a larger resection, which increased the difficulty of trauma and postoperative recovery of patients. In order to solve this problem, positioning needles or special dyes were usua...
