Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pushing device for capsule endoscopes. Background Technology

[0002] Capsule endoscopy, a novel method for examining the small intestine, typically measures 11mm x 27mm, resembling a capsule-shaped pill taken clinically, hence the name capsule endoscopy. This new endoscope's outer shell is made of a smooth polymer material, housing a miniature camera and video signal transmitter, and also includes a built-in battery. The battery life allows the miniature camera and video signal transmitter inside the capsule to operate continuously for 7-8 hours. After being swallowed, the capsule moves through the digestive tract using peristalsis, acquiring and transmitting video signals to a receiving device on the patient's skin. Patients can obtain imaging data of the entire small intestine painlessly.

[0003] When performing intestinal examinations using capsule endoscopy, problems such as poor gastric motility or pyloric spasm may prevent the capsule endoscope from passing through the stomach and entering the intestines, leaving it in the stomach. Because the capsule endoscope has limited battery power, it needs to be inserted into the duodenum using a regular gastroscope to quickly enter the intestines and achieve the purpose of the intestinal examination. Since capsule endoscopes are similar in shape to commonly consumed capsules and have a smooth surface, biopsy forceps or foreign body forceps cannot hold them. While snares or baskets can encircle the capsule endoscope, when the snare or basket is tightened, the field of vision at the tip of the endoscope is poor, making it difficult to effectively determine the direction of insertion. Pushing the capsule can easily cause damage to the gastrointestinal mucosa, or even perforation. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of inconvenience in pushing capsule endoscopes, which can easily cause damage to the gastrointestinal mucosa, and the poor field of vision caused by pushing with a net or snare, and to provide a pushing device for capsule endoscopes.

[0005] A pusher device for a capsule endoscope includes a sleeve and a connecting part integrally disposed at the bottom of the sleeve; the side surface of the sleeve is provided with a plurality of receiving grooves; and the connecting part and the middle of the sleeve are provided with a mounting hole.

[0006] Furthermore, the size of the receiving groove is matched with that of the capsule endoscope; the surface of the receiving groove is provided with a magnetic suction layer.

[0007] Furthermore, the receiving slots are configured as four, evenly arranged around the center of the sleeve.

[0008] Furthermore, the ends of the sleeve and the connecting part are configured with rounded chamfers.

[0009] Furthermore, the sleeve and connecting part are made of white transparent plastic.

[0010] The beneficial effects of this invention are: by placing the capsule endoscope into the sheath through magnetic attraction and then transporting the sheath to the duodenum through the endoscope, this device avoids the risk of damage to the gastrointestinal mucosa or even perforation.

[0014] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0015] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0016] Example 1

[0017] like Figures 1-2 As shown, a pushing device for a capsule endoscope includes a sleeve 2 and a connecting part 1 integrally disposed at the bottom of the sleeve 2. Specifically, the sleeve 2 and the connecting part 1 are preferably cylindrical structures, wherein the diameter of the connecting part 1 is smaller than the diameter of the sleeve 2. In order to achieve a fixed connection between the entire device and the end of the endoscope without affecting the endoscope's observation of the environment, a mounting hole 11 is provided through the middle of the connecting part 1 and the sleeve 2. The diameter of the mounting hole 11 is slightly larger than the diameter of the end of the endoscope, allowing the end of the endoscope to be connected with the mounting hole 11 by an interference fit.

[0018] To accommodate the capsule endoscope, the side surface of the sheath 2 is provided with multiple receiving slots 3; the front end of the receiving slot 3 protrudes from the front end of the sheath 2; the size and shape of the receiving slot 3 are matched with the capsule endoscope; in use, the capsule endoscope is placed into the receiving slot 3. In this solution, in order to accommodate multiple capsule endoscopes at the same time, four receiving slots 3 are provided, which are evenly arranged around the center of the sheath 2.

[0019] To secure the capsule endoscope, a magnetic layer 31 is provided on the surface of the receiving groove 3. Using magnetic attraction, the capsule endoscope can be stably attached to the receiving groove 3. Then, the endoscope is used to push the device into the duodenum, and the capsule endoscope can be shaken out of the device by gently vibrating the endoscope or lightly scraping it against the mucosa.

[0020] To avoid irritating the intestines during the pulling of the device, the ends of the sleeve 2 and the connecting part 1 are designed with rounded chamfers. To facilitate observation of the intestinal tract by the endoscope, the sleeve 2 and the connecting part 1 are made of white transparent plastic.

[0021] This device avoids the risk of gastrointestinal mucosal damage or even perforation by placing the capsule endoscope into the sheath via magnetic attraction and then delivering the sheath to the duodenum through the endoscope.

[0022] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
