Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device processing and manufacturing, and in particular to a device for cleaning the inside of tubular structures. Background Technology
[0002] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It contains an image sensor, optical lens, light source, and mechanical devices, and can be inserted into the stomach through the mouth or other natural orifices. Endoscopes can visualize lesions that X-rays cannot, making them extremely useful for doctors. For example, with an endoscope, doctors can observe ulcers or tumors in the stomach and develop the best treatment plan. It typically includes a rigid or flexible tube inserted into the body. Cleaning and disinfection are usually achieved using a cleaning device roughly matching the shape of the tube, utilizing a blade-like cleaning device at the head of the device combined with appropriate cleaning agents. However, because the human body contains mucus and deposits, cleaning is often difficult and these deposits tend to adhere to the inner wall of the tube. Existing cleaning devices cannot completely remove some stubborn mucus and deposits remaining on the inner wall during the cleaning process, thus requiring a more effective cleaning device. Summary of the Invention
[0003] This invention addresses the shortcomings of existing cleaning tools for internal feed devices, which have poor cleaning effects, by providing a cleaning device structure for cleaning endoscopic devices.
[0004] To achieve the above objectives, the present invention can adopt the following technical solution:
[0005] A device for cleaning the interior of a tubular structure comprises at least two elongated bodies intertwined, each body including a body A made of a material with elastic deformation, having protrusions spaced apart along its length; each protrusion is a flat shape formed by deformation of a portion of the body A; the flat shape of the protrusion extends along the length of the body A.
[0006] The material used to manufacture the body A is metal or rigid plastic.
[0007] The protrusion extends radially away from the body A.
[0008] An angle is formed between adjacent protrusions along the length of the body A. The flat protrusions also have a curvature in their extending direction.
[0009] The distance the protrusion extends along the length direction of the body A is less than the distance it extends along the radius direction of the body A.
[0010] The main body A is intertwined with other bodies in a spiral manner.
[0011] The angle between the length direction of body A, which is wound around other bodies in a spiral manner, and the length direction of the wound device is between 20° and 40°.
[0012] This utility model has the following significant technical effects:
[0013] For better cleaning results, multiple angled protrusions can be formed on the surface of the device. During the process of pulling out the cleaning device, these protrusions evenly scrape away the stains attached to the inner wall of the tube and help the cleaning agent and stains react. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the embodiments. Example
[0017] like Figure 1 , 2 As shown, due to the scale, Figure 1 Showing only a portion of the protrusions, this is a device for cleaning the interior of a tubular structure. The cleaning device is formed by intertwining at least two elongated bodies 100. Each body 100 includes a body A101 made of an elastically deformable material, with protrusions 102 spaced apart along its length. Each protrusion 102 is a flattened shape formed by deformation of a portion of the body A101, extending along the length of the body A101. After intertwining with other bodies, these protrusions 102 are evenly distributed around the body A101. When cleaning the interior of the tubular structure, pulling these cleaning devices allows the protrusions 102 to scrape against the inner wall of the tubular structure. Since the interior of the tubular structure is filled with cleaning agent, this also helps to agitate the cleaning agent, accelerating the cleaning process. Furthermore, the protrusions 102 themselves can directly scrape away stains from the inner wall. The multiple protrusions 102 work together to effectively and completely clean the interior of the tubular structure.
[0018] Furthermore, the material used to manufacture the body A101 is metal or rigid plastic. It can be manufactured by applying pressure and stretching the original elongated cylindrical body A101 directly using a mold or a mechanical device to obtain a flat protrusion 102.
[0019] Furthermore, the protrusion 102 extends radially away from the body A101.
[0020] Furthermore, adjacent protrusions 102 are provided with an included angle in the length direction of the body A101, that is, when viewed from the length direction of the body A101, the protrusions 102 are uniformly arranged around the body A101.
[0021] Furthermore, the protrusion 102 is arc-shaped in its extending direction.
[0022] Furthermore, the distance by which the protrusion 102 extends along the length direction of the body A101 is less than the distance by which it extends along the radius direction of the body A101.
[0023] Furthermore, the body A101 is wound around the other bodies 100 in a spiral manner.
[0024] Furthermore, the angle between the length direction of the body A101, which is wound with other bodies 100 in a spiral manner, and the length direction of the wound device is between 20° and 40°.
[0025] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
