Navigation display system for lung operation puncture

Abstract

The invention belongs to the field of clinical medicine manufacturing, and particularly provides a navigation display system for lung surgery puncture, which comprises a path planning module, an optical positioning module and a navigation display module, initializing a marking photosphere coordinate and a puncture path under the same physical coordinate system through a path planning module; then, an optical positioning module is used for combining the recognizable and displayable marking light ball with the steel needle to form a puncture navigation steel needle; and finally, uniformly representing the three-dimensional model of the puncture navigation steel needle and the three-dimensional model of the lung structure by an optical coordinate system through a navigation display module, and displaying the relationship between the puncture navigation steel needle and the lung structure in real time through an optical locator. The system is applied to a lung puncture positioning navigation operation, the optical coordinate of the puncture navigation steel needle is obtained through the optical tracking device, the optical coordinate and the physical coordinate are mutually converted, real-time display of the puncture navigation steel needle in the navigation system is achieved, the puncture success rate is increased, and the operation time of a patient is shortened.

Description

technical field [0001] The present invention relates to the technical field of clinical medicine, and more particularly, to a navigation display system for puncture in lung surgery. Background technique [0002] With the development of high-resolution CT scanning technology, more and more sub-millimeter nodules that are difficult to characterize have been discovered. In recent years, the improvement of minimally invasive surgical techniques has made it possible to perform local tumor resection through thoracoscopy. However, pulmonary nodules are small and compacted and consolidated after lung tissue, so it is difficult to guide the resection of small nodules by palpation, and the resection of lung lobes or lung segments is too traumatic, so the localization of small pulmonary nodules is very important. [0003] In this regard, the Chinese Patent Publication No. CN108514643A discloses a preoperative color and tactile marking method for tiny pulmonary nodules. The marking meth...
