Detailed Description

Referring to fig. 1 to 6, a preferred embodiment of an anal fistula seton directional cutting wire grip includes a sleeve 10, a rubber band 20 and two guide wires 30.

The sleeve pipe 10 top has first entry 11 and second entry 12, sleeve pipe 10 bottom is equipped with an export 13 with two entry homogeneous phases switch-ons, sleeve pipe 10 bottom inner wall still is equipped with the chucking subassembly, two guide silk threads stretch into and all stretch out from export 13 from sleeve pipe 10's first entry 11, second entry 12 respectively, its both ends are tied up respectively on the guide silk thread 30 that stretches out from first entry 11 and second entry 12 after the fistulous way of hanging a line is passed to rubber band 20 one end, can pull out the rubber band 20 both ends to sleeve pipe export 13 when forcing to take up two guide silk threads 30 that stretch out from export 13, and the end to end both ends of rubber band 20 all with chucking subassembly looks jamming fit. As shown in FIG. 6, the rubber band 20 is provided at both ends with a collar 24 to facilitate the binding between the guide wire 30 and the rubber band 20.

In this embodiment, as shown in fig. 2, the clamping assembly includes two clamping portions arranged oppositely, each clamping portion includes a transverse section 21 and an inclined section 22, two ends of each transverse section 21 are respectively connected to the inner wall of the casing 10 and one end of one of the inclined sections 22, the other end of the inclined section 22 is suspended, a clamping channel 23 is formed between the two inclined sections 22, and two ends of the rubber band 20 are tightly clamped with the clamping channel 23. The two inclined sections 22 not only can realize clamping fit with the two ends of the rubber band 20, but also have the function of one-way guiding.

In this embodiment, the distance between the two inclined sections 22 is gradually decreased from top to bottom.

In this embodiment, the minimum distance between two inclined sections 22 is less than or equal to the diameter of one rubber band 20. In practical design, the minimum distance between the two inclined sections 22 is set to 2 mm, and the diameter of one rubber band 20 is 2 mm. The minimum distance between the two inclined sections 22 is smaller than or equal to the diameter of one rubber band 20, so that the clamping channel 23 can clamp the two ends of the rubber band 20, and the two ends of the rubber band 20 are prevented from being separated from the clamping channel 23.

In this embodiment, the sleeve 10 is Y-shaped, the first inlet 11 is located at the top end of the left side of the sleeve 10, and the second inlet 12 is located at the top end of the right side of the sleeve 10.

In this embodiment, the top surface of the sleeve 10 is circular arc-shaped, and the circular arc-shaped top surface extends from the first inlet 11 to the second inlet 12. When in actual design, the radian of the arc-shaped top surface is designed to be 45 degrees, so that the effect is optimal. The top surface of the sleeve 10 is arc-shaped, the arc-shaped top surface extends from the first inlet 11 to the second inlet 12, the arc-shaped top surface is in smooth transition, and the arc-shaped top surface can be attached to the skin of a patient in the using process, so that the good contact experience of the patient is provided, and the comfort level of the patient is improved.

In this embodiment, the sleeve 10 is made of medical silica gel.

The use process of the directional tightener is as follows:

two guide silk threads respectively extend into the first inlet 11 and the second inlet 12 and respectively extend out of the outlet 13, and enough length is reserved at two ends of the two guide silk threads outside the sleeve;

then, one end of the rubber band 20 is kept outside the patient body, the other end of the rubber band 20 passes through the line fistulization channel and then extends out of the patient body, then, two lantern rings 24 of the rubber band 20 are respectively tied with one ends of two guide silk threads 30 extending out of two inlets, then the two guide silk threads 30 extending out of the outlet 13 are tensioned by force, then, the two ends of the head and the tail of the rubber band 20 pass through the clamping channels 23 and then extend out of the sleeve 10 from the outlet 13, and the two ends of the rubber band are kept clamped under the clamping action of the inclined sections 22 of the two clamping parts. When the wire needs to be tightened, only one hand needs to hold the sleeve 10, and the other hand pulls the two ends of the rubber band 20 outwards to proper positions and then loosens the two ends, so that the use is very convenient.

The directional tightener can guide cutting force from a mechanical angle to perform directional cutting from inside to outside, reduces the damage of anal sphincter, and can also reduce the pain of a patient caused by tightening a hanging wire to the maximum extent.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
