[0021] In order to more clearly understand the above purpose, features and advantages of the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced according to other embodiments that can not be described in detail herein, and the present application is not limited to the embodiments described herein.

[0023] As shown in Figure 1 and Figure 2 According to one embodiment of the present application, the protective cover for taking out foreign matter in the digestive tract is a multi-section structure, which comprises a protection section 1 at the front end, a visual expansion section 2 at the middle, and a gastroscope fixing section 3 at the rear end. When the gastroscope is fixed on the gastroscope fixing section 3, the protection section 1 is wrapped on the gastroscope.

[0024] In this embodiment, the protection section 1 at the front end of the protective cover is soft and tough, which can be reversely sleeved on the upper end of the gastroscope, i.e. the protection section 1 is sleeved on the gastroscope, and then is sent to the foreign matter together with the gastroscope. After the foreign matter is grabbed, the gastroscope and the protective cover can be withdrawn together. Due to the resistance, the protective cover is naturally reversed to the direction of the foreign matter, i.e. the protection section 1 opens to wrap the foreign matter in the protection section 1, thereby protecting the esophagus, stomach, intestine and other digestive tract tissues from being damaged by the foreign matter.

[0025] In the above embodiment, preferably, the protection section 1 is in a flared mouth structure.

[0026] In this embodiment, the flared mouth structure can accommodate foreign matters of different lengths and sizes, so that the process of taking out the foreign matter is safer and more smooth.

[0027] In any of the above embodiments, preferably, the protection section 1 is made of a medical elastomer material.

[0028] Specifically, the medical elastomer material is natural latex, water-based polyurethane, polyisoprene or polyurethane.

[0029] In this embodiment, the whole protective cover can also be made of a medical elastomer material, so it has certain expansion and wrapping performance, which can effectively cooperate with the tip of the gastroscope, and can cooperate with the tips of multiple gastroscope of different sizes, so the application range is more extensive.

[0030] As shown in Figure 1 and Figure 2 In any of the above embodiments, preferably, the diameter of the visual expansion section 2 is greater than the diameter of the gastroscope fixing section 3.

[0031] Specifically, the visual expansion section 2 and the gastroscope fixing section 3 form a beveled transition section 4 in diameter.

[0032] In this embodiment, the visual expansion section 2 with a diameter greater than the gastroscope fixing section 3 can provide a wider surgical field of view for medical personnel.

[0033] As Figure 1 and Figure 2 In any of the above embodiments, preferably, the inner wall of the gastroscope fixing section 3 is formed with a retaining ring 5 in the circumferential direction, which has a limiting effect on the gastroscope when the gastroscope fixing section 3 is mounted on the gastroscope.

[0034] In this embodiment, during the mounting of the gastroscope on the gastroscope fixing section 3 and the entry of the gastroscope into the esophagus, stomach, intestines and various digestive tract tissues, the retaining ring 5 can prevent the gastroscope from being excessively deep into the gastroscope fixing section 3 and affecting the surgical field due to excessive installation force or under the action of resistance.

[0035] As Figure 1 and Figure 2 In any of the above embodiments, preferably, the gastroscope fixing section 3 is formed with a side hole 6, which is located on the opposite side of the gastroscope 7 corresponding to the retaining ring 5.

[0036] In this embodiment, through the side hole 6, water can be injected as needed during the mirror process. Leaving a side hole 6 can facilitate the outflow of water to prevent accumulation in the transparent cap and affect the field of view. The side hole 6 can also prevent the mucosa from being sucked into the gastroscope fixing section 3 and causing damage, ensuring the safety and effectiveness of the treatment process.
