Abstract

The utility model relates to an anal fistula seton, which comprises an elastic thread body, wherein a plurality of uniformly distributed annular bulges are arranged on the outer wall of the elastic thread body; the clamping plate is provided with a clamping groove extending from the edge to the center, and the width of the clamping groove is not larger than the diameter of the annular protrusion. This technical scheme is located fistulous way both ends position card with the elastic wire body after tying up fixedly for the first time and goes into the draw-in groove, the elastic wire body should be in tensile state when tying up, the card resets through elastic contraction after going into the draw-in groove, and play spacing fixed action through annular bulge, when the later stage needs to tighten up the elastic wire body, only need take out the cardboard, further tighten up the elastic wire body, then go into the cardboard once more later position can, the operation degree of difficulty has been reduced in very big degree, the convenience of operation has been improved.

Description

Anal fistula hanging wire

Technical Field

The utility model relates to the field of treatment appliances, in particular to an anal fistula seton.

Background

Anal fistula, also known as anal canal rectal fistula, is a granulation swelling canal in which the anal canal or rectum communicates with the perianal skin, mainly invades the anal canal and rarely involves the rectum, so the anal fistula is usually called anal fistula, with the inner opening located near the dentate line and the outer opening located at the perianal skin. The whole fistula wall is composed of thickened fibrous tissues, and a layer of granulation tissues is covered in the fistula wall, so that the fistula wall is not healed for a long time.

The thread-hanging therapy is suitable for high-position simple or complex anal fistula, can avoid postoperative anal incontinence caused by one-time incision, fracture and contraction of sphincter, and has wide clinical application and simple and convenient operation. The operation method is that under anesthesia, a probe is firstly inserted from an external orifice, penetrates out along a fistula through an internal orifice, a rubber band is tied on the probe at the internal orifice, then the rubber band is led out from the internal orifice through the fistula at the external orifice, the skin between the internal orifice and the external orifice is incised, and the rubber band is tightened to be ligated. The thread can be tightened again after 3-5 days of operation, the rubber band falls off within 1-2 weeks after operation, the left open wound surface can be gradually healed, if the rubber band does not fall off after two weeks, the tissue tied by the rubber band can be cut off by scissors or the thread can be tightened again.

The secondary tightening of the hanging wire needs to be loosened firstly and then bound, and the hanging wire is thin and has high operation difficulty, so that the problem of how to provide the hanging wire convenient for multiple times of tightening is urgently needed to be solved.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems in the prior art, the utility model provides an anal fistula seton which is convenient for tightening operation for multiple times.

The technical scheme for solving the technical problems is as follows:

an anal fistula seton comprises an elastic thread body, wherein a plurality of uniformly distributed annular bulges are arranged on the outer wall of the elastic thread body;

the clamping plate is provided with a clamping groove extending from the edge to the center, and the width of the clamping groove is not larger than the diameter of the annular protrusion.

Further defined, the width of the opening of the card slot is less than the width of the bottom.

Further limiting, and the centers of the two sides of the clamping plate are provided with inwards sunken arc-shaped concave pits.

Further limited, the diameter of the elastic thread body is 1-1.2mm, and the diameter of the annular bulge is

1.5-2mm。

Further defined, the edge of the clamping plate is of an arc-shaped structure.

The utility model has the beneficial effects that:

after the elastic wire body is bundled and fixed for the first time, the elastic wire body is positioned at the two ends of the fistula and clamped into the clamping grooves, the elastic wire body is in a stretching state when being bundled, the elastic wire body is reset through elastic contraction after being clamped into the clamping grooves, and the annular bulges play a role in limiting and fixing;

the structure that the width of the opening of the clamping groove is smaller than the width of the bottom can play a certain limiting role, and the clamping groove of the sliding groove of the elastic thread body is reduced to a certain extent;

the arc-shaped concave pits are used as matching limiting parts of the annular bulges and the clamping plate and used as accommodating spaces of the annular bulges, so that the annular bulges are fixed, and the stability of a fixing structure between the elastic wire body and the clamping plate is further improved;

the edge of the clamping plate is of an arc-shaped structure, so that the clamping plate has a smooth surface to reduce the discomfort of a patient during use.

FIG. 2 is an enlarged view of A in FIG. 1;

FIG. 3 is a schematic structural view of the card;

in the drawings, the components represented by the respective reference numerals are listed below:

elastic line body 1, annular protrusion 2, cardboard 3, draw-in groove 4, arc pit 5.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1, 2 and 3, the anal fistula seton comprises an elastic thread body 1, wherein a plurality of uniformly distributed annular bulges 2 are arranged on the outer wall of the elastic thread body 1;

the clamping plate is characterized by further comprising a clamping plate 3, wherein a clamping groove 4 extending from the edge to the center is formed in the clamping plate 3, and the width of the clamping groove 4 is not larger than the diameter of the annular protrusion 2.

The opening width of the clamping groove 4 is smaller than the bottom width.

The centre of the two sides of the clamping plate 3 is provided with an inward sunken arc-shaped concave pit 5.

The diameter of the elastic thread body 1 is 1-1.2mm, and the diameter of the annular bulge 2 is 1.5-2 mm.

The edge of the clamping plate 3 is of an arc-shaped structure.

In this embodiment:

after the elastic wire body 1 is tied up and fixed for the first time, the elastic wire body 1 is positioned at the two ends of the fistula and clamped into the clamping grooves 4, the elastic wire body 1 is in a stretching state when being tied up, the elastic wire body is reset through elastic contraction after being clamped into the clamping grooves 4, and the annular protrusions 2 play a role in limiting and fixing;

the structure that the opening width of the clamping groove 4 is smaller than the width of the bottom can play a certain limiting role, and the outside of the sliding groove clamping groove 4 of the elastic thread body 1 is reduced to a certain extent;

the arc-shaped concave pits 5 are used as matching limiting parts of the annular bulges 2 and the clamping plates 3 and are used as accommodating spaces of the annular bulges 2, so that the annular bulges 2 are fixed, and the stability of a fixing structure between the elastic wire body 1 and the clamping plates 3 is further improved;

the edge of the clamping plate 3 is of an arc-shaped structure, and the clamping plate has a smooth surface, so that the discomfort of a patient in use is reduced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
