Description

Technical Field

[0001] The utility model relates to the technical field of tying rings, in particular to a rubber tying ring structure. Background Art

[0002] Hemorrhoid ligation is one of the commonly used methods for treating hemorrhoids. The principle is to ligate the root (or base) of the hemorrhoids to block the blood supply to the hemorrhoidal tissue, causing it to atrophy and fall off due to ischemia, thereby achieving the purpose of healing. As a commonly used medical device, the ligation loop plays a key role in surgical operations and interventional treatments.

[0003] The ligation tool commonly used in hemorrhoid ligation devices is a rubber ligation ring. The traditional rubber ligation ring is a circle. As the placement time increases, the rubber ligation ring is easily oxidized, and the elastic retraction force gradually weakens. It cannot ensure that the hemorrhoidal blood vessels are completely occluded after the ligation operation, making the hidden danger of bleeding after the ligation operation unavoidable. Utility Model Content

[0004] 1. Technical issues to be resolved

[0008] Furthermore, the improvement of the utility model is that the anti-sliding block is a hemispherical structure.

[0009] Furthermore, the present invention is improved in that the sizes of the plurality of anti-sliding blocks are the same.

[0010] In order to facilitate the assembly of the reinforcement ring, the improvement of the utility model is that the reinforcement ring is bonded to the inside of the annular groove.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a rubber tying ring structure, which has the following beneficial effects:

[0015] The rubber ligature ring structure can provide an additional rebound effect to the ligature ring through the reinforcement ring. When the rebound effect of the ligature ring weakens, the reinforcement ring can still make the ligature ring rebound, thereby improving the stability of the ligature ring when in use.

[0016] By providing the first reinforcing layer, the first protective layer, the second reinforcing layer and the second protective layer, the ligation ring and the reinforcing ring are not easily oxidized as the placement time increases, which can improve the stability of the ligation ring and the reinforcing ring during use, ensure that the hemorrhoidal blood vessels are completely occluded after the ligation operation, and avoid the hidden danger of bleeding after the ligation operation.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The rubber tying ring structure of the utility model comprises a tying ring 1 and a reinforcing ring 2. The tying ring 1 is provided with an annular groove 3 on its circumference, and a plurality of anti-sliding blocks 4 are provided on the inner wall of the annular groove 3. The reinforcing ring 2 is fixed inside the annular groove 3, and the reinforcing ring 2 contacts the anti-sliding blocks 4. The surface of the tying ring 1 is provided with a first reinforcing layer 5 and a first protective layer 6 in sequence, and the surface of the reinforcing ring 2 is provided with a second reinforcing layer 7 and a second protective layer 8 in sequence.

[0024] In this structure, by providing a plurality of anti-sliding blocks 4, the reinforcing ring 2 can prevent the ligation ring 1 from being completely attached in the annular groove 3, and a plurality of cavities can be provided between the reinforcing ring 2 and the ligation ring 1, so that the structure can be more portable when in use;

[0025] The reinforcement ring 2 can provide an additional rebound effect to the ligation ring 1. When the rebound effect of the ligation ring 1 weakens, the reinforcement ring 2 can still make the ligation ring 1 rebound, thereby improving the stability of the ligation ring 1 when in use.

[0026] By providing the first reinforcing layer 5, the first protective layer 6, the second reinforcing layer 7 and the second protective layer 8, the ligation ring 1 and the reinforcing ring 2 are not easily oxidized as the placement time increases, which can improve the stability of the ligation ring 1 and the reinforcing ring 2 during use, ensure complete occlusion of the hemorrhoidal blood vessels after the ligation operation, and avoid the risk of bleeding after the ligation operation.

[0027] Furthermore, the anti-sliding block 4 is a hemispherical structure, and the sizes of the plurality of anti-sliding blocks 4 are the same.

[0028] Furthermore, the reinforcement ring 2 is bonded to the inside of the annular groove 3, and the bonding method has the advantage of convenient assembly.

[0029] Furthermore, the ligation ring 1 and the reinforcement ring 2 can both be made of rubber material.

[0030] Furthermore, the first reinforcement layer 5 and the second reinforcement layer 7 are both coated with a silane coupling agent, which can react chemically with the rubber material to form a chemical bond, thereby improving the rubber's anti-oxidation performance. This coating can enhance the rubber's weather resistance, water resistance, and chemical corrosion resistance, and extend the service life of the rubber tying ring 1. The first protective layer 6 and the second protective layer 8 are both coated with an ultraviolet absorber, which contains special compounds that can absorb ultraviolet rays. When ultraviolet rays irradiate the coating, these compounds absorb the ultraviolet rays and convert them into heat energy or other harmless forms, thereby preventing ultraviolet rays from damaging the rubber tying ring 1.
