Description

Technical Field

[0001] The present invention relates to the technical field of anorectal disease treatment, and more specifically to an anti-slip-off rubber ring for internal hemorrhoid rubber band ligation and an internal hemorrhoid ligation assembly. Background Art

[0002] Internal hemorrhoid is a common anorectal disease. Its essence is a varicose venous blood vessel mass, which is clinically usually manifested as a soft mass formed by the dilation and varicosity of the submucosal blood vessel plexus at the end of the rectum above the anal dentate line. The rubber band ligation method is a treatment method for internal hemorrhoids. Its working principle is to use an instrument to put a rubber band around the root of the internal hemorrhoid and utilize the elasticity of the rubber band to block the blood supply of the internal hemorrhoid, so that the internal hemorrhoid necrosis, falls off due to ischemia and achieves self-healing. At present, the problems existing in this treatment plan are: when the patient defecates daily, the rubber band may slip off from the feces due to friction, which may lead to the failure of this round of treatment, thereby reducing the treatment success rate and indirectly increasing the patient's treatment duration. In addition, the current hemorrhoid rubber band usually uses a clamp structure to briefly hold the hemorrhoid nucleus during the ligation process, causing pain to the patient. Therefore, how to develop a new anti-slip-off rubber ring for internal hemorrhoid rubber band ligation and a new internal hemorrhoid ligation assembly to overcome the above problems existing in the prior art is the direction that those skilled in the art need to further study. Summary of the Invention

[0034] Example 1, please refer to Figures 1-4 :

[0035] An internal hemorrhoid ligation assembly includes: an outer shell 100, a pulling handle 310, a negative pressure tube 410, and a negative pressure pump 500.

[0036] The structure of the outer shell 100 is similar to a pistol, and includes an extension tube 110 extending in the horizontal direction and a hand-held grip 120 extending in the vertical direction. The outer shell 100 is also provided with a mounting hole 130. A limit tube 330 is detachably mounted at the tube mouth of the extension tube 110; two return springs 210 are installed inside the outer shell 100; one end of the two return springs 210 are respectively fixedly mounted on the inner wall of the outer shell 100, and the other ends of the two return springs 210 are respectively fixedly connected to the positioning ring 220 as a whole;

[0037] The middle section of the handle body of the pulling handle 310 is movably mounted on the mounting hole 130, and the active end of the pulling handle 310 extends out of the outer shell 100 through the mounting hole 130; the driven end of the pulling handle 310 is located in the outer shell 100 and is hingedly connected to the head end of the rod body of the pulling rod 320; the tail end of the rod body of the pulling rod 320 is hingedly connected to the positioning ring 220; the pulling handle 310 is configured so that the active end of the pulling handle 310 can reciprocate relative to the mounting hole 130;

[0038] The head end of the tube body of the negative pressure tube 410 extends out of the extension tube 110 and is connected to the rubber ring sleeve tube 430. The anti-slip-off rubber ring 700 is detachably sleeved on the outer surface of the tube body of the rubber ring sleeve tube 430. The outer diameter of the tube body of the rubber ring sleeve tube 430 is the same as the inner diameter of the tube body of the limit tube 330. The middle section of the tube body of the negative pressure tube 410 is located inside the outer housing 100 and is fixed integrally with the positioning ring 220. The rubber ring sleeve tube 430 is configured such that the tube orifice of the rubber ring sleeve tube 430 extends out of the limit tube 330 / retracts into the limit tube 330 as the active end of the pulling handle 310 rotates reciprocally relative to the mounting hole 130. The tail end of the tube body of the negative pressure tube 410 is conductively connected to the head end of the tube body of the hose 420, and the tail end of the tube body of the hose 420 extends out of the outer housing 100 and is conductively connected to the negative pressure pump 500 / the operating room negative pressure connector.

[0039] An anti-slip-off rubber ring 700, and the anti-slip-off rubber ring 700 is an annular rubber ring. Anti-slip lines are distributed on the inner side wall of the annular rubber ring. The anti-slip lines can be wave-shaped anti-slip lines 810. The wave-shaped anti-slip lines 810 are composed of a plurality of uniformly distributed raised particles 820. The wave-shaped anti-slip lines 810 can also be composed of a plurality of uniformly distributed raised barbs 830. In practice, the annular rubber ring can also be made of an elastic material, the inner side wall of the annular rubber ring is a conical surface, and the corrugated lines are distributed on the conical surface.

[0040] In practice, its working process is as follows: During the treatment process, first rotate the pulling handle 310, overcome the elastic force of the return spring 210 to extend the tube orifice of the rubber ring sleeve tube 430 out of the limit tube 330, then put the anti-slip-off rubber ring 700 on the outer wall of the rubber ring sleeve tube 430, insert the tube orifice of the rubber ring sleeve tube 430 into the anus and align it with the hemorrhoid. Start the negative pressure pump 500. The end of the hemorrhoid is adsorbed inside the tube orifice of the rubber ring sleeve tube 430 under the action of vacuum negative pressure, and the root of the hemorrhoid moves to be flush with the tube orifice of the rubber ring sleeve tube 430. Retract the tube orifice of the rubber ring sleeve tube 430 to the outside of the anus, and then pull the pulling handle 310 to make it rotate reversely under the action of the return spring 210. At this time, the negative pressure tube 410 resets and retracts, driving the tube orifice of the rubber ring sleeve tube 430 to retract into the limit tube 330. During this process, the tube orifice of the limit tube 330 squeezes the anti-slip-off rubber ring 700 to make the anti-slip-off rubber ring 700 sleeve on the root of the hemorrhoid. Finally, turn off the negative pressure pump 500, and the process of sleeving the anti-slip-off rubber ring 700 on the hemorrhoid is completed.

[0041] In practice, when the anti-slip rubber ring 700 adopts a certain structure, the device may further include a cone 610, which is used to assist in installing the anti-slip rubber ring 700 with a conical inner wall on the outer wall of the rubber ring sleeve pipe 430. Specifically: the bottom surface of the cone 610 is adapted to the nozzle of the rubber ring sleeve pipe 430. When installing the anti-slip rubber ring 700, insert the bottom surface of the cone 610 into the nozzle of the rubber ring sleeve pipe 430, and then sleeve the anti-slip rubber ring 700 along the cone 610 onto the outer wall of the rubber ring sleeve pipe 430. In practice, a pressure relief valve 440 connected to the negative pressure pipe 410 in conduction may also be installed on the outer wall of the outer housing 100. The pressure relief valve 440 is normally in a closed state. When the anti-slip rubber ring 700 fails to be sleeved, briefly open the pressure relief valve 440 and then restore it to the closed state, and the pressure in the negative pressure pipe 410 can be relieved, thus facilitating re-operation.

Even if various changes are made to the present invention, provided that these changes fall within the scope of the claims of the present invention and its equivalent technologies, they still fall within the protection scope of the present invention.
