[0026] An endoscope is a medical diagnosis and treatment tool that allows doctors to directly observe the condition of internal organs in the body. The basic principle of an endoscope includes inserting a slender tube (endoscope) into body cavities or natural ducts, such as the digestive tract, respiratory tract, etc., so as to be able to visualize and examine these parts. An endoscope usually consists of a light source, a camera, and a transmission system, which can transmit images from internal organs to a display for doctors to observe and analyze.

[0027] During the endoscopy process, water supply and air supply are two important steps, each playing a key role:

[0028] 2. Water supply:

[0029] Clean the field of view: By supplying water, food residues, secretions, or blood in the gastrointestinal tract can be washed away, keeping the field of view clear and facilitating doctors to observe the internal situation.

[0030] Flush the biopsy hole: During endoscopy, samples may be taken or treatment operations may be performed through the biopsy hole. Supplying water can help flush the hole to prevent the sample or secretion from blocking.

[0031] 1. Air supply:

[0032] Expand the field of view: By supplying air, the gastrointestinal tract can be inflated, making it easier for the endoscope to pass through the tortuous digestive tract. At the same time, the expanded organizational structure is more convenient for observation.

[0033] Push the endoscope forward: Supplying air can also help push the endoscope forward, especially in difficult areas such as the pylorus or the duodenal flexure.

[0034] Reduce irritation: Air insufflation can, to a certain extent, reduce the irritation and discomfort caused by the endoscope contacting the digestive tract wall.

[0035] During endoscope operation, the doctor will control the amount of water and air insufflation as needed, and sometimes pause the water and air insufflation according to the specific situation for specific operations such as biopsy, stone extraction, or treatment. Therefore, water and air insufflation during endoscope operation are very important technical steps, ensuring the smooth progress of the examination and the clarity of the image.

[0036] To prevent air leakage at the opening 1 of the endoscope forceps channel, a sealing cover is generally provided at the opening 1 of the endoscope forceps channel. Then this sealing cover needs to be opened for use. After opening, gas will leak. If the sealing cover is not opened, air leakage will also occur after a long time of use. For this reason, this case is born. Design an air leakage prevention sealing structure to prevent air leakage at the opening 1 of the endoscope forceps channel. In view of the above problems, an embodiment of the present utility model provides an air leakage prevention sealing structure for the opening 1 of the endoscope forceps channel, as Figure 2-5 shown, connected to the opening 1 of the endoscope forceps channel, with the forceps wire 2 passing through it internally. The air leakage prevention sealing structure includes a tube body 3. A number of air leakage prevention movable flaps 4 are arranged at equal angles on the inner circumference of the tube body 3. The air leakage prevention movable flaps 4 are inclined towards the rear end, and a number of air leakage prevention movable flaps 4 converge towards the center with each other to prevent gas from leaking out of the opening 1 of the endoscope forceps channel.

[0037] In the above technical solution, it is necessary to consider the elastic force of a number of air leakage prevention movable flaps 4 converging towards the center. After using for a certain period of time, especially during the continuous insertion and extraction of the forceps wire 2, the elasticity will weaken. In order to prevent air leakage due to weakened elasticity, further, as Figure 5 and 6 shown, in the above technical solution further, an elastic abutting member is provided at the rear end of the air leakage prevention movable flap 4. The elastic abutting member includes a number of wedge-shaped sliders 5, a spring 6, and a retaining ring 7. The retaining ring 7 is arranged inside the tube body 3. The wedge-shaped sliders 5 are slidably arranged inside the tube body 3 at the rear end of the air leakage prevention movable flap 4, and the spring 6 is arranged between the wedge-shaped sliders 5 and the retaining ring 7.

[0038] As Figure 4 shown, the number of a number of air leakage prevention movable flaps 4 is four, that is, the common cross shape. The corresponding number of wedge-shaped sliders 5 is four. In terms of arrangement, the wedge-shaped sliders 5 are arranged in a staggered manner with a number of air leakage prevention movable flaps 4, that is, located in the middle of two adjacent air leakage prevention movable flaps 4, for further air leakage prevention.

[0039] As Figure 3 and 6 shown, a pair of convex strips 8 are provided on the front end face of the wedge-shaped slider 5. The convex strips 8 can better abut against the air leakage prevention movable flap 4 and play a good elastic force role on the air leakage prevention movable flap 4.

[0040] AsFigure 5 and 6 As shown in 6 , a dovetail slider 9 is provided on the wedge slider 5, and a dovetail groove 10 is provided on the corresponding tube body 3. The dovetail slider 9 is connected in the dovetail groove 10, which can make the wedge slider 5 slide more smoothly in the tube body 3.

[0041] Furthermore, as Figure 3 and 5 shown, a number of pre - placed anti - air - leakage movable flaps 11 are arranged at equal angles in the circumferential direction inside the tube body 3 at the front end of the anti - air - leakage movable flap 4, forming a secondary anti - leakage structure to enhance the anti - air - leakage effect.

[0042] There are various connection methods between the tube body 3 and the endoscopic forceps channel opening 1. In the embodiment of this case, as Figure 5 shown, preferably, an external thread 12 is provided at the outer end of the tube body 3, and an internal thread is provided inside the corresponding endoscopic forceps channel opening 1. The tube body 3 is threadedly connected to the endoscopic forceps channel opening 1.

[0043] As Figure 5 shown, a tube cap 13 covers the port of the tube body 3, and the tube cap 13 is connected to the tube body 3 through a connecting rope 14.

[0044] Working principle: When the anti - air - leakage sealing structure of the endoscopic forceps channel opening 1 is used, first install the tube body 3 into the endoscopic forceps channel opening 1 through the external thread 12, then open the tube cap 13, and then insert the forceps wire 2 into the tube body 3. The forceps wire 2 passes through the center of the pre - placed anti - air - leakage movable flap 11. The pre - placed anti - air - leakage movable flap 11 forms a wrap around the forceps wire 2, forming the first - level anti - air - leakage barrier. Then the forceps wire 2 passes through the center of the anti - air - leakage movable flap 4 and the wedge slider 5. Under the elastic force of the spring 6, a number of wedge sliders 5 generate a forward elastic force, which abuts against the anti - air - leakage movable flap 4, making the anti - air - leakage movable flap 4 better gather around the forceps wire 2, forming a secondary anti - air - leakage barrier.

[0045] In summary,

[0046] For the anti - air - leakage sealing structure of the endoscopic forceps channel opening 1, through the anti - air - leakage movable flaps 4 arranged at equal angles in the circumferential direction inside the tube body 3, when the forceps wire 2 is inserted, they can gather towards the center mutually, well - wrap the forceps wire 2, and prevent gas from leaking out of the endoscopic forceps channel opening 1;

[0047] The air leakage prevention sealing structure of the endoscope forceps channel opening 1 strengthens the wrapping force of the air leakage prevention movable flap 4 on the forceps wire 2 through an elastic stopper arranged at the rear end of the air leakage prevention movable flap 4. The elastic stopper includes a plurality of wedge-shaped sliders 5, a spring 6, and a retaining ring 7. The wedge-shaped sliders 5 are slidably arranged in the pipe body 3 at the rear end of the air leakage prevention movable flap 4, and the spring 6 is arranged between the wedge-shaped sliders 5 and the retaining ring 7. At the same time, the wedge-shaped sliders 5 are arranged between two adjacent air leakage prevention movable flaps 4, further blocking the gap between the two adjacent air leakage prevention movable flaps 4.
