Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a gastroesophageal mucosa protection device for gastroscopy. Background Technology

[0002] Gastroscopy is a commonly used medical device. To reduce damage to the esophagus and other parts of the body during clinical operation, a protective device is usually installed at the end of the endoscope tube. This device can enclose the foreign object clamp, preventing damage to the esophagus and other parts. However, after years of work, the following problems have been found with the current protective device: First, the existing protective device is manufactured separately in multiple parts and then assembled together. Although this can save on manufacturing costs, if the parts detach during use, it can lead to serious accidents and poses a risk. Second, gastroscopes are usually equipped with a nozzle for cleaning the lens. The existing protective device makes it difficult to drain water when the nozzle sprays water to clean the lens, resulting in incomplete cleaning of the lens. Therefore, the protective device of the gastroscope needs to be improved. Utility Model Content

[0003] To address the above problems, this utility model provides a gastroesophageal mucosa protection device for gastroscopy, which solves the problems of gastroscopy protection devices being easily detached during use due to their multiple components, posing a high risk of use, and causing inconvenience in draining water when cleaning the lens.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a gastroesophageal mucosa protection device for gastroscopy, comprising an integrally formed connecting part and a protective part, wherein the connecting part and the protective part are completely interconnected. A drain outlet is provided on the connecting part, which runs through both the inner and outer sides of the connecting part and is close to the protective part.

[0005] As a further improvement to the above solution, a first step is provided on the inner wall of the connecting part, and the first step contacts the surface of the endoscope tube. The port of the connector is provided with a second step to facilitate locking with the surface of the endoscope tube, and a guide surface is also provided on the second step.

[0006] As a further improvement to the above solution, an outwardly protruding reinforcing rib is provided on the outer surface of the connecting part, and the drain outlet passes through the reinforcing rib.

[0007] As a further improvement to the above solution, the outer surfaces of the connecting part and the protective part are smoothly transitioned, and the protective part is flared. The thickness of the connecting part is greater than the thickness of the protective part.

[0008] As a further improvement to the above solution, a support step is provided on the inner wall of the protective part.

[0009] As a further improvement to the above solution, a protrusion is provided on the inner wall of the protective part, and several perforations are provided on the protrusion.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By making the connecting part and the protective part into a single integrated structure, the installation process can be reduced, thereby reducing the instability of both during use. The drain port on the connecting part allows some of the cleaning water from the nozzle to be discharged from the lens, reducing the obstruction of the water flow, thus facilitating drainage and improving the cleaning effect on the lens.

[0011] The first and second steps enhance the stability of the connection at the end of the endoscope tube, thereby reducing safety risks during use.

[0012] The support steps are designed so that when the foreign body clamp retracts, they can be pushed out to cause the protective part to contract and deform inward, thereby reducing the size of the bell-shaped opening of the protective part. Similarly, the protrusions and perforations allow the pull wire inserted into the perforation to connect with the foreign body clamp. When the foreign body clamp retracts, it pulls the protective part inward, thereby minimizing irritation and secondary damage to the patient's esophagus and protecting the esophageal mucosa.

[0015] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0016] Example 1:

[0017] like Figure 1-3 The image shows Embodiment 1 of this utility model. The specific solution of this embodiment is: a gastroesophageal mucosa protection device for gastroscopy, comprising an integrally formed connecting part 10 and a protective part 11, wherein the connecting part 10 and the protective part 11 are completely interconnected. (Refer to the attached image.) Figure 2 As shown, the connecting part 10 is cylindrical, and the protective part 11 is flared. The outer surfaces of the connecting part 10 and the protective part 11 are smoothly connected. By connecting the connecting part 10 and the protective part 11 together, the possibility of the connecting part 10 and the protective part 11 falling off during use can be reduced while the connecting part 10 and the protective part 11 are integrally formed, thus improving the safety factor. The thickness of the connecting part 10 is greater than the thickness of the protective part 11. By making the thickness of the protective part 11 thinner, the shrinkage of the protective part 11 can be ensured when the foreign body clamp 21 retracts. At the same time, the hardness of the protective part 11 can be reduced, which makes it easier to reduce irritation and secondary damage to the esophagus during use, thereby improving the protective effect on the esophageal mucosa. A drain outlet 12 is provided on the connecting part 10. The drain outlet 12 passes through the inner and outer sides of the connecting part 10 and is close to the protective part 11. The drain outlet 12 allows the water sprayed by the nozzle 19 to be discharged from the drain outlet 12 after cleaning the lens 20, reducing the obstruction of the water flow by the protective part 11 and thus improving the cleaning effect of the lens 20.

[0018] In a preferred embodiment, a first step 13 is provided on the inner wall of the connecting part 10, and the first step 13 contacts the surface of the endoscope tube 18; a second step 14 is provided at the port of the connecting part 10 to facilitate locking with the surface of the endoscope tube 18, and a guide surface is also provided on the second step 14, such as... Figure 2 As shown, the guide surface on the second step 14 facilitates the insertion of the endoscope tube 18 into the connecting part 10. The second step 14 can clamp the endoscope tube 18 on the surface, thereby preventing it from falling off.

[0019] As a preferred embodiment of the above, a reinforcing rib 15 protruding outward is provided on the outer surface of the connecting part 10, and the drain outlet 12 passes through the reinforcing rib 15. The reinforcing rib 15 mainly serves to further strengthen the connecting part 10, which facilitates the stability after installation on the endoscope tube 18.

[0020] Example 2:

[0021] like Figure 4 , 5As shown, as Embodiment 2 of this utility model, this embodiment is a further improvement on Embodiment 1. Specifically, the inner wall of the protective part 11 is provided with a support step 16. The support step 16 is thicker, so when the foreign object clamp 21 retracts, it will press against the edge of the support step 16, thereby improving the effect of the protective part 11 shrinking towards the middle, reducing the size of the protective part 11, and reducing the irritation to the esophagus.

[0022] Example 3:

[0023] like Figure 6 , 7 As shown in Embodiment 3 of this utility model, this utility model is a further improvement on Embodiment 1. Specifically, the improvement is as follows: a protrusion 17 is provided on the inner wall of the protective part 11, and a plurality of perforations 171 are provided on the protrusion 17. After the wire is inserted into the perforation 171, the wire and the foreign object clamp 21 are connected together. When the foreign object clamp 21 retracts, the perforation 171 is pulled, so that the protective part 11 contracts and becomes smaller, thus reducing the irritation to the esophagus.

[0024] Furthermore, a slip ring or sliding block can be installed on the foreign object clamp 21 to fix the pull wire connected to one end of the foreign object clamp 21 to the slip ring or sliding block. In this way, when the foreign object clamp 21 extends outward, it will not be restricted by the wire, and when it retracts, the clamp can press against the slip ring, causing the slip ring and the wire to pull the protective part 11 inward, making it smaller and shrinking.
