Description

towable capsule endoscopy

technical field

The utility model relates to a towable capsule endoscope.

Background technique

Capsule endoscopy, also known as "medical wireless endoscopy", is based on the principle that the subject takes a smart capsule with a built-in camera and signal transmission device orally, and uses the peristalsis of the digestive tract to make it move in the digestive tract and take images, and the doctor uses the images outside the body to record Instruments and imaging workstations, to understand the entire digestive tract of the subject, so as to make a diagnosis of his condition. Capsule endoscopy has the advantages of convenient inspection, no trauma, no wires, no pain, no cross-infection, and no imaging of patients' normal work. It can be used as the first choice for the diagnosis of digestive tract diseases, especially small intestinal diseases. However, the existing capsule endoscopes are all swallowed and then excreted from the body by the intestinal tract. Not only does it stay in the body for a long time, but it is also impossible to artificially control the position and time of the capsule endoscope staying in the digestive system. In addition, this capsule endoscope It is also a one-time use, and the cost is also high, which limits the scope of application and is difficult to popularize in the market.

Utility model content

The purpose of the utility model is to provide a towable capsule endoscope, which solves the problem that the endoscope capsule in the prior art cannot artificially control the position, time and return of the capsule endoscope in the digestive system.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

The towable capsule endoscope includes a capsule endoscope, one end of the capsule endoscope is provided with a connection device, and a connection line for pulling the capsule endoscope is also connected to the connection device, and the diameter of the connection line is not greater than 2mm.

Further, the connecting wire is wrapped with a protective layer.

Still further, the connecting device is a small ring fixed on the capsule endoscope for connecting with the connecting wire, or a through hole provided on the capsule endoscope for connecting with the connecting wire. In addition, the connecting wires can also pass through small circles or through holes to form double wires.

Furthermore, a pull ring is provided at the end of the connecting wire away from the capsule endoscope.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) The utility model is provided with a connection device at one end of the capsule endoscope, and a connection line is also provided on the connection device, the diameter of which is less than 2mm. During clinical operations, the clinician can control the capsule endoscope through the connection line. The staying position in the patient's digestive system, and the time of staying in the digestive system can be controlled at the same time, so that more images can be taken to meet the needs of clinicians for disease diagnosis; in addition, the connecting line can pass through the connecting device to form a double line , when the inspection is completed, one of the ends can be pulled out from the connecting device to facilitate the release of the capsule endoscope.

(2) The utility model is wrapped with a protective layer on the connecting wire. When the connecting wire enters the digestive system, it can effectively avoid the damage of the connecting wire to the human body and play a very good protective role.

(3) There is also a pull ring on the connecting line of the utility model. After checking the patient's digestive system, the capsule endoscope can be pulled out slowly and conveniently by pulling the ring. After infection, it can be disinfected and reused. The inspection cost is greatly reduced, and the capsule endoscope will not stay in the human body for a long time, thereby reducing the pain of the patient.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and examples. The implementation of the utility model includes but not limited to the following examples.

Example 1

As shown in Figure 1, the towable capsule endoscope includes a capsule endoscope 1, one end of the capsule endoscope 1 is provided with a connecting device 2, and the connecting device 2 is also connected with a connecting wire 3 for pulling the capsule endoscope 1 , and the diameter of the connecting line is not greater than 2mm; in order to ensure that the external structure of the capsule endoscope and its small volume are not changed as much as possible, the connecting device is a small circle fixed on the capsule endoscope for connecting with the connecting line Ring, or a through hole provided on the capsule endoscope for connecting with the connecting wire, but this embodiment uses a small ring as the connecting device, and of course setting the through hole can also achieve the expected purpose of the utility model.

When the capsule endoscope 3 is pulled, the connecting wire 5 connecting the capsule endoscope may cause harm to the human body, so a protective layer is also provided on the connecting wire 5, the protective layer is preferably made of silica gel, and the connecting wire 5 is Wrapped with a thin silicone layer, the thickness of the silicone layer does not exceed 0.5mm.

In order to facilitate the clinician to pull the capsule endoscope out of the human body smoothly, a pull ring 4 is provided at the end of the connecting line 3 away from the capsule endoscope 1, and the doctor only needs to pull the pull ring to pull it out smoothly. Capsule endoscopy, easy to operate.

Example 2

As shown in Figure 2, the only difference between this embodiment and Embodiment 1 is that the connection line is not fixed on the small ring or the through hole, but passes through the small ring or the through hole to become a double line, and there is no connection line on the connection line. Set the pull ring. After the capsule endoscopy examination is completed, you only need to pull one end of the connecting wire to separate the connecting wire from the capsule endoscope to achieve the purpose of releasing the capsule endoscope. The connecting wire can be pulled out from the mouth, and the capsule endoscope will be discharged by itself in vitro.

Example 3

As shown in Figure 3, the towable capsule endoscope includes a capsule endoscope 1, the tail end of the capsule endoscope 1 is provided with a connecting device 2, and the connecting device 2 is also connected with a connecting line for pulling the capsule endoscope 1 3, and the diameter of the connecting wire is not greater than 2mm; in order to ensure that the external structure of the capsule endoscope and its small volume are not changed as much as possible, the connecting device is a small device fixed on the capsule endoscope for connecting with the connecting wire A circular ring, or a through hole provided on the capsule endoscope for connecting with a connecting wire.

In order to prevent the connection line from being too dry and making it difficult to enter the patient's digestive system, a dropper is fixedly connected to the end of the connection line away from the capsule endoscope. The end of the connection line is located in the mouth of the dropper. Cut the diameter of the connection line Just equal to the inner diameter of the dropper nozzle, when the patient swallows the capsule endoscope, the connecting wire can be moistened by slowly dripping water through the dropper to ensure that the connecting wire will not cause damage to the human body.

According to above-mentioned embodiment, just can realize the utility model well. It is worth noting that, based on the premise of the above-mentioned structural design, in order to solve the same technical problem, even if some insubstantial changes or embellishments are made on the utility model, the essence of the technical solution adopted is still the same as that of the utility model. same, so it should also be within the protection scope of the present utility model.
