Description

Technical Field

[0001] The utility model relates to the technical field of medical device equipment, and specifically relates to an instrument for controlling gastric emptying. Background Technique

[0002] The instrument for controlling gastric emptying is basically spherical in structure, and its function is to help people lose weight. The principle is to place the spherical structure at the gastric antrum (the gastric antrum is part of the structure of the stomach, and the "gastric antrum" clinically referred to is the pyloric antrum or the pyloric part including the pylorus, and the duodenum can be accessed through the narrow pylorus), reduce the gastric volume physically, and control the gastric emptying function, thereby reducing the food intake and ultimately controlling the weight.

[0003] The existing instruments for controlling gastric emptying are generally a cyst, which is hollow, and other auxiliary instruments are used to fill the cyst with a medium to make it expand. Specifically, reference can be made to a weight loss balloon device for adjustable gastric emptying disclosed in Chinese Patent CN213607223U, and an adjustable balloon system and adjustment method disclosed in Chinese Patent CN116492124A.

[0004] That is, the existing instruments for controlling gastric emptying all require auxiliary instruments to assist their expansion, and have complex structures and high manufacturing costs. Content of the Utility Model

[0005] The purpose of the utility model is to provide an instrument for controlling gastric emptying to solve at least one of the problems raised in the above background technique.

[0006] To solve the above technical problems, the utility model provides the following technical solution: an instrument for controlling gastric emptying, comprising: a main body for implanting at the gastric antrum, the surface of the main body being composed of smoothly connected curved surfaces; and an auxiliary body for implanting at the gastric antrum to fix the main body, the auxiliary body being connected to or integrally formed with the main body;

[0007] The main body of this instrument has a certain supporting force and hardness, and is directly implanted into the stomach in its own shape. Different from the traditional scheme prepared by rubber and inflated by filling a medium, it can be adjusted by a hemostatic forceps under an endoscope after implantation, so that the auxiliary body is hooked at the pylorus to prevent the main body from shifting. No special auxiliary instrument is required during the implantation process, and only a common endoscope is needed.

[0008] Further, the main body is one of a spherical shape, a water droplet shape, a columnar shape, a gourd shape, and a string shape, and these shapes can all conform to the shape of the gastric antrum.

[0009] Further, the main body or the auxiliary body is prepared from one of the materials of silica gel, metal, ceramic, and plastic. Specifically, the main body is a rigid structure with a certain supporting performance, and the auxiliary body can be a rigid structure or a soft structure.

[0010] Further, to reduce weight, the main body has a hollow structure.

[0011] Further, the hollow portion of the main body may also be filled with a medium, which can be air or liquid.

[0012] Further, to facilitate the operation of the hemostat on the auxiliary body, through holes are formed on the auxiliary body for the jaws of the clamp to extend into.

[0013] Further, in some embodiments, the auxiliary body is an annular hose that passes through a hole formed in the main body, and the through hole is formed by the annular hose. The jaws of the clamp can extend into the annular hose to control the main body, so that the instrument can be rotated to a suitable orientation and displaced to a suitable position.

[0014] Further, there is one or more auxiliary bodies. When there are multiple auxiliary bodies, they can better fix the main body. That is, multiple auxiliary bodies can be hung on the pylorus to form relative fixation. BRIEF DESCRIPTION OF THE DRAWINGS
