Description

Traction recyclable capsule endoscope Technical field

The invention relates to a capsule endoscope, in particular to a capsule endoscope which can be recycled and reused, and belongs to the technical field of medical instruments.

Background technique

According to available medical data, hundreds of thousands of people worldwide die of upper gastrointestinal cancer every year. The upper digestive tract refers to the mouth, pharynx, upper digestive tract, stomach, small intestine (duodenum) of the human body, and upper gastrointestinal cancer. The incidence rate and mortality rate vary greatly from country to country. China is one of the regions with high incidence of digestive tract cancer in the world, and the incidence rate in rural areas is much higher than that in urban areas. Medical clinical trials have shown that early upper gastrointestinal detection and prevention can effectively reduce the incidence of upper gastrointestinal cancer. The prior art mainly relies on X-ray on the upper digestive tract and on the upper gastrointestinal tract to detect the upper digestive tract. The lesions, due to the high cost of this kind of detection method, are difficult to be widely popularized in some remote areas; and the detection process is complicated, which has certain requirements for the technical level of medical personnel; secondly, the volume of the upper digestive tract is generally large. The detection process may cause damage to the upper gastrointestinal lesions, and the patient needs to endure the adverse reactions caused by the upper gastrointestinal tract during the whole detection process, which further aggravates the patient's condition.

In view of the problems existing in traditional gastrointestinal lesion detection devices, medical personnel have tried to adopt a medical wireless endoscope system (referred to as "capsule endoscope"). Capsule endoscopy is a new type of non-invasive and painless digestive tract and upper digestion. The wireless detection system of the channel consists of capsules and external image recorders that implement upper gastrointestinal detection functions. Due to the use of micro-optical electromechanical technology, the size of the smart endoscope is small, and the patient does not need anesthesia during swallowing. Freedom of movement eliminates the pain and inconvenience of traditional testing methods. Because this technology has great commercial interests and application prospects, and has the advantages of simple operation, painless, no cross infection, capsule endoscopy is favored by more and more researchers at home and abroad.

However, clinical trials have shown that existing capsule endoscopy still has some technical problems in the detection of upper gastrointestinal lesions. For example, Patent No. 201220135353.3, entitled "Capsule Endoscopy", discloses a capsule endoscope in which the patient swallows the capsule endoscope and excretes it with the feces after the test is completed. In order to avoid cross-infection, the capsule endoscope is a disposable product, which results in the expensive parts inside the capsule not being recycled multiple times, causing unnecessary waste, and increasing the cost of patient testing; secondly, the capsule endoscope is on The power source of movement in the digestive tract is mainly provided by the flow of fluid in the upper digestive tract. Medical personnel cannot flexibly control their movement in the upper digestive tract. Not very ideal.

In combination with the technical problems existing in the capsule endoscopes in the prior art, it is required that a capsule endoscope can flexibly reciprocate back and forth in the upper digestive tract to achieve more accurate detection, and can realize multiple recycling and no use. Cross-infection reduces the cost of a single test and reduces the workload of medical staff.

The technical problem to be solved by the invention is that the existing capsule endoscope can not flexibly reciprocate back and forth in the upper digestive tract, and can be accurately positioned and detected, and can not achieve multiple recycling, and no cross infection, and at the same time in the working process capsule Endoscopy can cause damage to the upper digestive tract.

In order to solve one or more of the above technical problems, the present invention provides a traction type recyclable capsule endoscope, comprising an information receiving and processing device, a control circuit, a first optical window cover, and an LED lamp disposed around the CMOS lens.
