Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a ring-breaking device for treating anal fistula. Background Art

[0002] Anal fistula is mainly caused by infected abscesses around the rectum and anal canal, forming a chronic infection channel between the anus or rectum and perineal skin. The treatment of anal fistula is mainly achieved through surgery. The purpose of the surgery is to remove the lesion, clear the drainage, minimize the damage to the anal sphincter, and protect the anal function. For low-position or high-position simple anal fistulas with internal and external openings within 3 to 5 cm from the anal margin, or as an auxiliary treatment for complex anal fistula incision and resection, hanging thread therapy is usually selected. Hanging thread therapy is a method of slowly cutting the anal fistula tract with a rubber band or medical thread.

[0003] In the prior art, when doctors use hanging wire therapy, they generally use special instruments for treatment or remove replaceable rubber rings from other medical consumables for treatment; for existing special instruments, they basically use hanging rings for treatment, and each hanging requires a set of equipment. At the same time, during the treatment process, the tightness of the coil cannot be further adjusted; it is impossible to continuously apply pressure to the treatment area, and a good treatment effect cannot be achieved; for the method of removing replaceable rubber rings from other medical consumables for treatment, medical staff generally remove the rubber ring on the wrist of the rubber glove and use it instead. Multiple rings are required for each treatment, resulting in a waste of resources. Utility Model Content

[0014] The adjusting head comprises a U-shaped groove arranged on the side wall, the U-shaped groove protrudes relative to the end of the adjusting head and is arranged opposite to an end of the observation guide notch close to the adjusting head.

[0015] The looping device also includes a limiting body, which is fixedly connected to one end of the elastic line passing through the tail end, and the size of the limiting body is larger than the diameter of the through hole.

[0016] The length of the threading needle is greater than the length of the adjusting rod.

[0017] The material of the threading needle is copper, silver, gold, aluminum or zinc.

[0018] The value range of the tension F that the rubber ring can withstand is: 2N≤F≤20N.

[0019] The outer wall of the active head end of the adjusting rod is provided with an external thread, the adjusting head is provided with an internal thread, and the active head end of the adjusting rod is threadedly connected with the adjusting head.

[0020] The beneficial effects of the utility model are as follows: the utility model is a device for treating anal fistula, comprising an adjusting rod and an adjusting head; a knot is formed at the knot bearing part at the action head end in the middle of the elastic line; one end passes through the through hole and is connected and positioned with a limiter; the other end is connected with a threading needle; when the threading needle drives the elastic line to pass through the anal fistula opening and then pass through the anus, it passes through the through hole of the adjusting rod, and passes through the middle of the knot while passing through the action head end of the through hole; the size of the threading needle passing through is adjusted to achieve the adjustment of the tightness of the elastic line at the action part, and the elastic line is adjusted relatively.

The knot is positioned and the guide end is pulled, so that the action pressure can be continuously adjusted during the whole treatment process to avoid the problem of poor effect; at the same time, during the treatment process of the present application, multiple rubber rings can be guided and fixed between the anal fistula and the anus through the threading needle, avoiding the waste of resources. In addition, the action head end of the adjusting rod of the present application is provided with a wire ring tightening hole. After the knot has acted for a period of time, when it needs to be tightened and pressed for a second time, the guide end of the elastic line can also be passed through the wire ring tightening hole, and the wire knot can be limited through the wire ring tightening hole. The guide end is pulled to realize the secondary tightening of the elastic line, which is more convenient to operate and avoids the problem that the knot end and the guide end are too short to be tightened for a second time.
