Color and touch labeling method for lung micro-nodule before surgery

Abstract

The invention discloses a color and touch labeling method for a lung micro-nodule before surgery. The labeling method is characterized by including the following steps that a solution of methylene blue, thrombin and calcium chloride and a fibrinogen solution are prepared, two different injectors are connected with a lung puncture needle through a t-branch pipe respectively, and the two solutions are injected to the lesion position of the lung micro-nodule simultaneously through the injectors to form a blue gel nodule in the lesion position. The blue gel nodule is visible and touchable, a surgery doctor can conduct accurate positioning and excision on the lung micro-nodule through the vision and touch; the needed medicines are easy to get and low in price, the effect can last for two days or more after labeling, and thus flexible selection of the surgery opportunity is facilitated.

Description

technical field [0001] The invention relates to the technical field of marking methodology for surgical treatment of tiny pulmonary lesions, in particular to a color and tactile marking method for tiny pulmonary nodules before surgery. Background technique [0002] Lung cancer is currently the most common malignant tumor in the world, and its morbidity and mortality rate ranks first among all malignant tumors. In recent years, with the continuous development of inspection methods, the detection rate of early lung cancer, mainly manifested by small pulmonary nodules with a diameter of less than 1 cm, has increased significantly, allowing more lung cancer patients to receive early surgical treatment and thus survive for a long time. [0003] Minimally invasive video-assisted thoracoscopic surgery is the most effective and preferred treatment for this kind of early-stage lung cancer that manifests as tiny nodules, and can make patients survive for a long time. One of the keys ...

Problems solved by technology

If isotope labeling is used, not only isotope pollution, but also difficult to accurately locate; while using barium sulfate and lipiodol labeling requires the use of X-ray fluoroscopy during the operation to locate, which is inconvenient and unnecessary for the operator to accept X-ray exposure. In addition, The above two contrast agents are also easy to diffuse, resulting in inaccurate positioning
