Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments for gastroenterology, in particular to an endoscope-assisted traction device. Background Art

[0002] The Department of Gastroenterology mainly studies and treats clinical diseases of the stomach, large intestine, small intestine, esophagus, etc. Since most of the diseases in the Department of Gastroenterology occur in the abdominal cavity, it is necessary to use digestive endoscopes such as gastroscopes, colonoscopes, duodenoscopes, etc. for clinical examinations. Since the endoscope needs to be inserted into the patient's body, a part of the endoscope is a soft tube structure so that it can be inserted into the body and bend. The endoscope needs to be removed quickly, and the acceptance level of patients is different, and the removal speed requirements are also different. The existing traction device is difficult to achieve traction adjustment at different removal speeds; if biopsy sampling is required at the lesion, the gastroscope can only observe the effect but it is difficult to take samples. Therefore, an auxiliary traction device is proposed, which can assist in traction and sampling. Utility Model Content

[0034] In the embodiments of the present disclosure, as shown in the attached Figure 3 and attached Figure 6 As shown, a through groove 401 is provided on the roller 4, and an axis slot 402 is provided at the end of the through groove 401 and the center of the roller 4. The width of the through groove 401 is greater than the maximum width of the movable shaft 22. The through groove 401 can satisfy the flipping action of the roller 4, and the axis slot 402 can be rotated with the long insertion rod 2202 as the axis to flip the roller 4. After the roller 4 is moved with the insertion shaft 3 as the axis, the inner tube 7 can be pulled out by the roller 4 and gradually separated from the patient's body. The roller 4 can increase the friction with the outer wall of the inner tube 7, so that the pulling speed can be adjusted arbitrarily.

[0035] In the embodiments of the present disclosure, as shown in the attached Figure 4 As shown, a slot 2201 is provided on the movable shaft 22, and a long plug rod 2202 and a short plug rod 2203 are inserted inside the slot 2201. A push plate 2204 is welded on one side of the two groups of movable shafts 22 that are close to each other, and the push plate 2204 is connected to the end of the connecting cable 501.

The connecting cable 501 passes around the fixed column inside the connecting ring 102. After pressing the roller 4 toward the middle, the two movable shafts 22 will be pressed to move toward the middle. The built-in spring is compressed and drives the two push plates 2204 to move toward the middle at the same time, so that the connecting cable 501 can push the rack plate 52 forward and rotate the clamping member 6 for clamping. After releasing the roller 4, the two movable shafts 22 can be automatically pushed to reset through the built-in spring.

[0039] In the embodiments of the present disclosure, as shown in the attached Figure 1 and attached Figure 5 As shown, a transverse circular hole is opened inside the connecting ring 102, and a connecting cable 501 is connected to the inside of the circular hole through a built-in spring, and the connecting cable 501 passes through the inside of the connecting tube 101. The inner diameter of the connecting tube 101 is larger than the outer diameter of the inner tube 7.

An arc groove is opened on the outside of the main body 1, which can better fit the curvature of the finger, conforms to the principle of ergonomics, improves the grip comfort, and is more convenient to use.

[0040] The working principle of this embodiment is: when biopsy sampling is not required, after the roller 4 is moved with the insertion shaft 3 as the axis, the inner tube 7 can be pulled out by the roller 4 and gradually separated from the patient's body;

[0041] When sampling is required, the insertion shaft 3 is taken out and separated from the movable shaft 22. After flipping the rollers 4, the two rollers 4 are pressed toward the middle, and the movable shaft 22 is driven to move toward the middle at the same time. The rack plate 52 is pushed forward by the push plate 2204, and the fixed gear shaft 51 is driven to rotate through meshing, and then the incomplete tooth ring 603 is driven to rotate, so that the clamping part 6 is rotated and closed, so that the internal air of the inner tube 7 is sealed, and the front end of the inner tube 7 has an adsorption effect. After sampling is completed, the inner tube 7 is pulled out.
