Abstract

The invention discloses a cruising locator for pulmonary minimal focuses under a thoracoscope. A navigation probe is arranged at the tip of a pair of lung grasping forceps, and a micro-electromagnetic sensor is arranged inside the navigation probe. The cruising locator is matched with an in-vitro electromagnetic locating panel, an electromagnetic patch and an electromagnetic navigation host, and is used for performing chest CT scanning and three-dimensional reconstruction on the scanned image to obtain a chest three-dimensional analog image, a doctor marks location and size of a doubtable focus position in the analog image and inputs the marked image to the electromagnetic navigation host, and the system is used for automatically simulating an optimized location navigation path, so that a pulmonary minimal focus can be easily located by utilizing the navigation probe under guidance of a real-time navigation system in the thoracoscopy. The cruising locator is simple in structure, can be used for accurately and quickly reaching a target focus and avoiding the operation risk generated when location is carried out in other operations, has relatively low requirement for doctors and patients, is safe and reliable to operate, and has a good practical value.

Description

technical field [0001] The invention relates to the technical field of thoracoscopic surgical instruments, in particular to a cruise locator for small pulmonary lesions under thoracoscopic surgery. Background technique [0002] With the development of imaging and the strengthening of lung cancer screening, the number of small pulmonary nodules has increased year by year. Video-assisted thoracoscopic technology has been widely used in the diagnosis and treatment of solitary small pulmonary nodules, which is an important factor limiting the success rate of surgery. It is whether the lesion can be located quickly and accurately. In the absence of safe, effective, and accurate positioning measures, some cases are forced to transfer to thoracotomy because the lesion cannot be found. [0003] At present, the localization techniques of pulmonary nodules mainly include the following four types: 1. Injected liquid localization: the injected liquid includes dyes such as methylene blue...
