Diagnosis and treatment system for precancerous lesions of gastrointestinal tract

Abstract

The invention provides a diagnosis and treatment system for precancerous lesions of gastrointestinal tract. The diagnosis and treatment system comprises a targeting probe capable of specifically recognizing precancerous lesions of the gastrointestinal tract, and one or any combination of antibodies in antibodies corresponding to proteins corresponding to gene banks with GenBank acceptance numbers of AF054162, AF054163, AF054164 and the like which can be adsorbed to the precancerous lesions of the gastrointestinal tract in a targeting manner and are highly expressed in precancerous lesion tissue. At least one or any combination of a molecular contrast agent and a light-absorbing and heat-producing functional substance is coupled to the antibodies. The capsule endoscope at least comprises a white light module, an ultraviolet light module and a near-infrared light module and is provided with multiple wavelength light sources, a capsule endoscope in-vivo position control module and an in-vitro image receiving module, the probe can specifically recognize and be adsorbed to the precancerous lesions of the gastrointestinal tract, targeted imaging detection is achieved under irradiation of the specific light source of the capsule endoscope, and the detection accuracy is improved. A novel specific detection and treatment system is provided for gastrointestinal precancerous lesions.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a system for diagnosing and treating precancerous lesions of the gastrointestinal tract. Background technique [0002] Gastrointestinal cancer has extremely high morbidity and mortality, and is one of the major diseases threatening human health. Gastrointestinal cancers are all evolved from precancerous lesions of the gastrointestinal tract, including gastric ulcers, gastric polyps, chronic atrophic gastritis, intestinal gland metaplasia, and dysplasia. At present, the early detection rate of gastrointestinal precancerous lesions in my country is low, and most of them are not treated in time, which increases the probability of evolving into cancer and directly causes the extremely high incidence of gastrointestinal cancer. The low detection rate of gastrointestinal precancerous lesions can be partly attributed to the fact that the symptoms are not obvious in the early stage, and a...

Problems solved by technology

However, the existing capsule endoscope can only relieve the pain of the examinee, but it cannot solve another major problem of the current conventional insertion endoscope, that is, the inspection can only be based on the change of the surface morphology of the gastrointestinal tract. It is impossible to diagnose precancerous lesions that do not cause obvious changes in the surface of the gastrointestinal tract. At the same time, it is difficult to find precancerous l
