Method of marking internal lesions position and marking agent

Abstract

The invention discloses a marking method and a marking agent for a focal position in a body. The marking method can utilize an endoscope device and a tool device being able to realize remote control that are connected mutually to apply the marking agent on the focal position, can find out the focal position in the body and simultaneously apply an accurate locating marker on the focal position to provide instruction for the next treatment so as to improve the operation efficiency and the cure rate of a disease. The marking agent of the invention has the advantages of developing in and out of the body, being identified by naked eyes and resisting oxidation and corrosion of liquid. Applying the marking agent on the focal position results in a remarkable sediment after coloration, thus being convenient for a doctor to find out the focal position accurately by visual in the body and be able to confirm a dissection position for the focal position through an exosomatic apparatus; thereby leading the doctor to clearly know the focal position before and during the operation, thus being beneficial to improve the efficiency of the operation and other cure methods. The marking agent of the invention can exit for a long time in the body, thus being convenient for the smoothness of the operation and other treatments.

Description

technical field [0001] The invention relates to a method for finding lesion sites in the body, in particular to a method for marking lesion sites in the digestive tract of a human body and a labeling agent thereof. Background technique [0002] Capsule endoscopy, born in the 1980s, has brought a major breakthrough in the diagnosis of digestive tract diseases. At present, capsule endoscopy is mainly used clinically, which is composed of a miniature camera, digital processing system, wireless transmission system, etc., and is combined with an image analysis and processing system to complete the image inspection in the body. It has the advantages of small size, light weight, convenient inspection, no trauma, no pain, no cross-infection, and does not affect the normal work of the examinee. The capsule endoscope in the prior art only realizes the function of finding the lesion, and does not perform positioning marking on the lesion. Doctors only make a diagnosis based on the im...
