Description

Technical Field

[0001] The utility model relates to the technical field of design and application of auxiliary tools for endoscopes, in particular to a special component for removing foreign bodies from the digestive tract based on an endoscope. Background Art

[0002] With the development of science and technology and the continuous progress of society, people's requirements for medical quality are getting higher and higher. One of the occasional emergency medical needs is that foreign objects may enter the digestive tract due to misoperation or accidents. Among the foreign objects in the digestive tract, there may be sharp points or corners, which may cause the foreign objects to get stuck in the digestive tract and difficult to remove.

[0003] At present, one of the most common treatment measures for foreign bodies in the digestive tract is to use foreign body forceps and snares with net bags to remove foreign bodies. However, they have some defects: some foreign bodies may be difficult to grasp during the removal process, and they may also easily damage the esophageal mucosa. Another hidden danger is that foreign bodies are easy to fall into the pharynx during the removal process, which may lead to the risk of aspiration and suffocation.

[0004] People are eager to obtain a tool for disposing foreign bodies in the digestive tract with excellent technical effects. Utility Model Content

[0005] The utility model provides a special component for removing foreign bodies in the digestive tract based on an endoscope, which is mainly used to help medical workers remove foreign bodies in the patient's digestive tract. The purpose of the invention of the utility model is to develop a cannula that can be pushed along the endoscope to achieve communication between the esophagus and the oral cavity, and at the same time use a balloon at the front end to expand the esophagus, remove the blockage between the esophagus and the foreign body, facilitate the removal of the foreign body, and prevent it from falling into the pharynx to cause more urgent and serious aspiration or suffocation.

[0006] The technical solution of the utility model is:

[0007] A special component for removing foreign bodies from the digestive tract based on an endoscope, which is used in conjunction with an endoscope; it is capable of removing foreign bodies through the instrument cavity of the endoscope; its technical key lies in: it includes: an endoscope sleeve base 1, an outer wall supporting airbag 2; wherein: the outer wall supporting airbag 2 is arranged at the proximal end of the front end of the endoscope sleeve base 1; the outer wall supporting airbag 2 is an eccentric airbag arranged eccentrically relative to the endoscope sleeve base 1.

[0008] The preferred technical content to be protected is:

[0009] When the outer wall support balloon 2 is inflated, the minimum distance between the outer wall of the endoscope sleeve base 1 and the outermost side of the entire cross-section of the dedicated component for endoscopic foreign body removal of the digestive tract is ≤2mm. The requirement here is actually to ensure that the endoscope sleeve base 1 is eccentrically arranged in the overall structure after the outer wall support balloon 2 is inflated, and the outer wall of the endoscope sleeve base 1 can be closer to the radial side edge of the support balloon 2 after inflation, so as to facilitate its stability.

[0011] A hydrophilic film layer 1.1 is provided on the outer wall of the endoscope casing substrate 1, and the thickness of the hydrophilic film layer 1.1 is ≤0.3 mm;

[0012] When the outer wall supporting airbag 2 is inflated, the cross-sectional diameter at the location thereof is 8 mm to 30 mm (a further preferred range is 15 mm to 22 mm).

[0013] After the outer wall supporting balloon 2 is inflated, on the cross section of the entire endoscope-based digestive tract foreign body removal dedicated component where the outer wall supporting balloon 2 is arranged, the cross section of the endoscope sleeve base 1 is inscribed at the outermost edge of the cross section of the entire endoscope-based digestive tract foreign body removal dedicated component, or the distance between the cross section and the outermost edge is ≤5mm (inscription is best, and the smaller the better if inscription is not possible, such as less than 1mm or less than 2mm);

[0014] After the outer wall supporting balloon 2 is inflated, the entire endoscope-based digestive tract foreign body removal special assembly with the outer wall supporting balloon 2 is located outside the digestive tract foreign body; this makes subsequent operations possible: we can extend the endoscope inward through the endoscope sleeve base 1, and then use instruments to clamp the foreign body and enter the inner cavity of the endoscope sleeve base 1 to remove the foreign body;

[0015] An inflation tube 2.1 is connected to the outer wall supporting balloon 2 and is fixedly arranged on the inner wall or in the inner cavity of the endoscope sleeve base body 1.

[0016] The outer wall support balloon 2 and / or the endoscope sleeve base 1 are provided with circumferential markings to distinguish the circumferential position of the eccentric outer wall support balloon 2;

[0017] A hydrophilic film layer 1.1 is arranged on the outer wall, and the thickness of the hydrophilic film layer 1.1 is ≤ 0.12 mm;

[0018] The endoscope sleeve base 1 can be controlled by the endoscope control end to rotate around the endoscope as the axis, so as to adjust its posture in the circumferential direction and achieve better technical effects.

[0019] The endoscope sleeve substrate 1 is preferably composed of a translucent, bendable support sleeve with a diameter of 1.5 cm, which has a certain support force, is not easy to deform, has a hydrophilic film, and has minimal friction with the endoscope surface.

[0020] The outer wall supporting airbag 2 itself has a certain elasticity, and the size of the outer wall supporting airbag 2 is controlled by air injection.

[0021] The gas injection channel of the outer wall supporting air bag 2 is connected to the other end through the inner cavity of the tube of the endoscope sleeve base 1 and is connected to the gas injection port.

[0022] The beneficial effects of the utility model are:

[0023] The utility model discloses a special component for removing foreign bodies in the digestive tract based on an endoscope for foreign bodies in the digestive tract (especially foreign bodies with sharp points or corners 9), which can realize the connection between the esophagus and the oral cavity. (The endoscope enters the esophagus from the oral cavity to reach the location of the foreign body, and the sleeve is pushed along the endoscope to the front end of the endoscope. The endoscope can see the sleeve and the foreign body at the same time. At this time, the air bag is inflated to expand the esophageal cavity, and the foreign body is unstuck and loosened. After entering the endoscope, the foreign body can be dragged out with a foreign body forceps or a net bag passing through the endoscope forceps channel. The utility model uses the eccentric airbag to help ensure that the endoscope sleeve base 1 is close to the outside of the foreign body in the digestive tract 8. After the outer wall support airbag 2 is inflated, the outer esophageal section can be propped up to relieve the esophagus and foreign body 9 from being blocked, making it easier to insert the endoscope from the inner cavity of the endoscope sleeve base 1 and insert foreign body forceps and other tools from the forceps channel (strong instrument) of the endoscope to remove the foreign body 9. At the same time, it can also prevent it from falling into the pharynx and causing aspiration or suffocation. The utility model can cleverly remove the foreign body 9, has a simple structure, strong operability, and excellent comprehensive technical effects. BRIEF DESCRIPTION OF THE DRAWINGS
