Abstract

A traction-type capsule endoscopy comprises a capsule endoscopy. One end of the capsule endoscopy is a non-free end provided with a traction flexible wire, the other end of the capsule endoscopy is a free end, and the traction flexible wire is connected with the capsule endoscopy through a connecting mechanism. The traction-type capsule endoscopy has the advantages that direct contact of the capsule endoscopy and the upper digestive tract is avoided, so the capsule endoscopy can be conveniently and repeatedly used, one-time detection cost of a patient is lowered, and popularization of the capsule endoscopy is facilitated; and the entire device is small in size and has a smooth outer surface, so adverse reactions of a patient in the detection process are largely reduced, and unnecessary damages to the upper digestive tract are avoided.

Description

Traction capsule endoscope

Technical field

The invention relates to a medical device, in particular to a capsule endoscope which is pulled by a cord and can be recycled and reused multiple times.

Background technique

Capsule endoscopy is a new type of wireless detection system for non-invasive and painless digestive tract and upper digestive tract. It consists of a capsule-shaped capsule and an in vitro image recorder that realize upper gastrointestinal detection function. The size of the smart endoscope is small, the patient does not need anesthesia and freedom of movement during swallowing, eliminating the pain and inconvenience caused by 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, the invention entitled "Capsule Endoscopy" discloses a capsule endoscope in which the patient swallows the capsule endoscope, and excretes with the feces after the detection is completed, in order to avoid cross infection, the species The capsule endoscope is a disposable product, which causes the expensive parts inside the capsule to not be recycled multiple times, resulting in unnecessary waste and increasing the cost of patient testing. Secondly, the power source of the capsule endoscope in the upper digestive tract mainly relies on The flow of fluid in the upper digestive tract provides that the medical staff cannot flexibly control the movement in the upper digestive tract; finally, the small size of the capsule endoscope does not cause the patient's uncomfortable reaction.

Therefore, in combination with the technical problems existing in the capsule endoscope in the prior art, it is required that the capsule endoscope can not only flexibly reciprocate back and forth in the upper digestive tract, but also can realize multiple recycling, no cross infection, and reduce The patient detects the cost in a single time and reduces the workload of the medical staff.

Summary of the invention

The technical problem to be solved by the present invention is that the flexible endoscopic movement of the capsule endoscope in the digestive tract cannot be controlled, and the existing capsule endoscope cannot be recycled and reused without cross-infection, and will be subjected to upper digestion. The problem of injury caused by the road.

In order to solve one or more of the above technical problems, the present invention provides a towed capsule endoscope comprising a capsule endoscope, wherein one end of the capsule endoscope is non-self From the end, the non-free end is provided with a traction cord, and the other end of the capsule endoscope is a free end, and the traction cord is connected to the capsule endoscope through a connection mechanism.

Further, the traction cord is a medical surgical line or a flexible cord made of a polymer material that is harmless to the human body.

Further, the connecting mechanism is a fixed cover (12), the fixed cover is provided with a fixing ring for fastening the traction cord, and the first permanent magnet is disposed in the fixed cover; the capsule endoscope The non-free end is provided with a second permanent magnet of opposite polarity to the first permanent magnet.

Further, the connecting mechanism is a snap ring, the snap ring includes a hook for fastening the traction cord and a lifting ring fixed to the non-free end of the capsule endoscope, the hook includes a traction cord for wearing A first hanging hole, a half moon ring and an elastic card for closing the opening of the half moon ring.

Further, the connecting mechanism is an adhesive layer, and the traction cord is adhered and fixed to the non-free end of the capsule endoscope through an adhesive layer.

Further, the connecting mechanism comprises a circlip and a circlip groove corresponding to the shape of the circlip, the circlip groove is disposed at a non-free end of the capsule endoscope, and the circlip is provided with a fixing ring for fastening the traction cord .

Further, the connecting mechanism comprises a micro-bolt and a threaded hole corresponding to the shape, the threaded hole is disposed at a non-free end of the capsule endoscope, and the micro-bolt is provided with a second hanging for fastening the traction cord hole.

Further, the connecting mechanism is a suction cup, one side of the suction cup is adsorbed on the smooth surface of the non-free end of the capsule endoscope, and the other side is provided with a third hanging hole for fastening the traction cord.

During the endoscopic examination, after the patient underwent the bowel cleansing work under the guidance of the doctor, the capsule endoscope completed by oral encapsulation, the capsule endoscope continued to penetrate along the upper digestive tract, and the medical staff slowly gave traction softly. The line and capsule endoscope continuously control the image in the digestive tract and transmit it to the external terminal display under the control of its control circuit. When the lesion is found, the medical staff only needs to stop the feeding of the traction cord, and the capsule endoscope can stay at the lesion for multiple shootings; if it is necessary to re-position the previous part of the upper digestive tract image, the medical staff only needs to drag back. The soft wire completes the flexible round-trip shooting of the capsule endoscope in the upper digestive tract.

Compared with the prior art, the traction capsule endoscope of the present invention has the following beneficial effects:

(1) avoiding the direct contact between the capsule endoscope and the upper digestive tract, thereby facilitating the multiple recycling of the capsule endoscope, reducing the single detection cost of the patient, and facilitating the popularization of the endoscope in multiple regions;

(2) The whole device is small in size and smooth in the outer surface, which greatly reduces the uncomfortable reaction of the patient during the detection process, and avoids unnecessary damage to the upper digestive tract.
