Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an esophageal mucosa protector. Background Art
[0002] In our daily life, people often get thorn-like bones (such as fish bones) stuck in their food, and they need to seek medical attention in time to remove the thorn-like bones (such as fish bones). Usually, doctors need to use endoscopes to view and remove thorn-like bones (such as fish bones). Endoscopes are important instruments for minimally invasive medical treatment. They are optical, mechanical, and electrical instruments that are precise and dexterous. They are composed of optical imaging, light sources, transmission, control handles, channels for other instruments (also called forceps channels), and image processing. Insert the digestive endoscope into the patient's esophagus through the mouth, find the location of the foreign body, use foreign body forceps to enter the esophagus through the forceps channel of the endoscope, operate the endoscope and foreign body forceps, and clamp the accidentally ingested thorn-like bones. Due to the size of the thorn-like bones, it is impossible to enter the forceps channel of the endoscope. The usual practice is to withdraw the endoscope and the foreign body forceps that clamp the thorn-like bones from the body at the same time. While this method removes the foreign body, the thorn-like bones may cause extensive damage to the esophageal mucosa along the esophagus, requiring further treatment. To this end, it is necessary to design a protective structure that can be used in combination with an endoscope so that the spur-like bone can be well wrapped when the spur-like bone is removed to avoid scratching the esophagus. Utility Model Content
[0003] The utility model aims to provide an esophageal mucosa protector, thereby effectively solving the problem that the esophagus is scratched by the thorn-like bone when it is pulled out.
[0004] The utility model solves the technical problem by adopting the following technical solution: an esophageal mucosa protector is arranged at the front end of an endoscope, and comprises a protective body made of an elastic flexible film and a binding wire for tightening the protective body;
[0005] The protective body includes a binding part for sleeved on the head of the endoscope and a binding part located at the front end of the binding part for protecting the esophagus; the binding wire is tied to the outside of the binding part to tighten the binding part; the free end of the binding wire passes through the protective body and is placed inside the protective body; the binding wire is tied to the binding part of the protective body in a slipknot weaving manner, and the slipknot can be opened by pulling the free end with force.
[0006] Furthermore, the bundling portion is a trumpet-shaped structure.
[0007] For easy operation, the front end of the bundling portion is an oblique structure.
[0008] In order to ensure that the front end of the bundling portion has a certain supporting force, a tension ring is provided at the front end of the bundling portion.
[0009] Preferably, the protective body is made of TPU or silicone rubber.
[0010] The beneficial effects of the utility model are as follows: the utility model is installed at the front end of the endoscope. When the thorn-like bone is pulled out, the thorn-like bone and the foreign body forceps are placed in the binding part of the protective body and withdrawn from the body together with the endoscope, thereby effectively preventing the thorn-like bone from scratching the esophagus when it is pulled out, and effectively protecting the esophagus. The binding part adopts a structure in which the binding line is tightened. When in use, the free end of the binding line is pulled, and the slipknot is opened by force to loosen the binding line, so that the binding part is opened, which is easy to operate. The flared and oblique mouth structure of the binding part facilitates the adjustment of the position to allow the thorn-like bone to enter. The tension ring provides a certain supporting force, so that the oblique mouth of the binding part can be as close to the esophageal wall as possible.
[0011] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the structure of the protective body in the utility model.
[0013] Figure 2 The utility model is a schematic diagram of the appearance of the utility model installed on an endoscope. DETAILED DESCRIPTION
[0014] Examples, such as Figure 1 , Figure 2 As shown, an esophageal mucosal protector is arranged at the front end of an endoscope 3, and is used to surround the thorn-like bone and then be removed together with the endoscope 3, thereby protecting the esophagus from being scratched by the thorn-like bone. The structure includes a protective body 1 made of an elastic flexible film and a binding wire 2 for tightening the protective body 1. The protective body 1 can be made of medical elastic materials such as TPU and silicone rubber, which are elastic and puncture-resistant.
[0015] The specific structure of the protection body 1 includes a binding part 11 for covering the endoscope head and a binding part 12 located at the front end of the binding part 11 for protecting the esophagus. The binding part 11 is a round tube structure adapted to the endoscope head. The binding part 12 is a trumpet-shaped structure and an oblique structure, and a tension ring 13 is provided at the front end of the binding part 12 for easy expansion.
[0016] In order to facilitate the trumpet-shaped binding part 12 to enter the esophagus, the binding part 12 is tied with the binding wire 2 to tighten the binding part 12. The free end of the binding wire 2 passes through the protective body 1 and is placed inside the protective body 1, so that the wire hook can hook the free end through the endoscope clamp hole and pull the free end of the binding wire 2 out of the operating handle of the endoscope.
[0017] The tying wire 2 is surrounded by the tying portion 12 in a slipknot knitting manner, such as a sweater knitting structure. The free end of the tying wire 2 is pulled hard to open the slipknot, thereby loosening the tying portion 12 and expanding the tying portion 12.
[0018] The specific use is described as follows, including the following steps: 1. First, insert the endoscope, find the position of the "thorn-like bone" through the endoscope, see clearly and record the scale value of the endoscope body corresponding to the incisor, and then withdraw the endoscope.
[0019] 2. Insert the wire hook from the endoscope's clamp opening, pass through the endoscope body, and emerge from the far end. Hang the free end of the binding wire on the protective body on the wire hook, and withdraw the wire hook until it is completely withdrawn, so that part of the binding wire also passes through the endoscope body, and the free end passes through the clamp opening. Remove the wire hook and prevent the free end of the binding wire from sliding into the clamp opening (it can be tied to the clamp opening).
[0020] 3. Put the binding part of the protective body onto the head end of the endoscope, and use medical tape to tie the binding part to tightly bind the protective body to the head end of the endoscope.
[0021] 4. Move the scope in again, until the set depth is reached, and the binding wire at the outer clamp entrance is pulled out. The second Open the slipknot and pull the binding wire until it is completely pulled out of the clamp opening to loosen the binding part of the protective body; let air flow into the esophagus through the endoscope, the esophagus at the endoscope lens position will expand, the tension ring of the protective body will relax, and the "thorn-like bone" can be seen through the endoscope.
[0022] 5. Insert the foreign body forceps from the forceps channel. When the forceps head reaches the head of the endoscope, use the foreign body forceps to adjust the position of the tension ring to make it close to the "thorn-like bone". Then clamp one end of the "thorn-like bone" with the foreign body forceps and pull it into the tension ring of the protective body. Finally, withdraw the foreign body forceps and the endoscope at the same time, allowing the protective body to remain on the surface of the "thorn-like bone" to protect the esophageal mucosa. Remove the endoscope and take out the "thorn-like bone".
