Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 5;

the utility model discloses a device is sewed up to scope with barb stylolite, include:

the clamping unit 4 is used for being fixed on tissues around a wound, a hole-shaped structure 6 or a slit structure 7 is arranged on one side, away from the fixed end, of the clamping unit 4, and the clamping unit 4 is a titanium clamp, a polymer clamp or an absorbable clamp.

The clamping unit 4 is provided with 2 arms 8 which can be opened, the ends of the two arms can be firmly closed, and a hole-shaped structure or a slit structure which can lead the suture to pass through is formed between the two arms after the two arms are closed.

A suture 1 with barbs 2, wherein the suture 1 can pass through the hole structure 6 or the slit structure 7 of the clamping unit 4 in one direction, and the suture 1 is a non-absorbable suture or an absorbable suture;

barb

2, 2 quantity of barb are a plurality of, distribute on stylolite 1 for the joint is structural at the passing through of centre gripping unit 4, prevents that stylolite 1 is reverse to pass through centre gripping unit 4.

1 tip of stylolite has fixed knot to be constructed, the fixed knot of 1 tip of stylolite is located stylolite 1's tip for joint clamping unit 4, it specifically is barb, knot or solid fixed ring 3.

The wound 5 in fig. 2, 3 belongs to a schematic illustration of a wound and does not belong to a part of an endoscopic suturing device with barbed sutures.

Specifically, the embodiment discloses an endoscope suturing device with barb stylolite 1, and the device is used for the processing of sewing up to wound 5, including clamping unit 4, two arms 8 of clamping unit 4 can press from both sides the back and fix on the near tissue of wound 5 and can not loosen and take off, form hole shape structure 6 or slit structure 7 between two arms 8, clamping unit 4 quantity is more than 2, and evenly distributed centre gripping is around wound 5, if the wound is less, can adopt less clamping unit 4, if the wound is great, can adopt more clamping unit 4, clamping unit 4 can be that titanium presss from both sides, the polymer presss from both sides or can absorb the clamp, and these all can conveniently purchase on the market. The suture 1 with the barbs 2 can pass through the hole-shaped structures 6 or the slit structures 7 on the clamping units 4 in a single direction, and the barbs 2 can be clamped on the hole-shaped structures 6 or the slit structures 7 to prevent the suture 1 from reversely passing through the clamping units 4.

The suture 1 with barbs 2 has barbs, knots or fixation loops 3 at the ends that fix the suture 1 to the gripping elements 4.

The following is a specific method of use of the endoscopic suturing device with barbed sutures, and the technical solution of the present invention will be more apparent from the following description of the method of use, but the method of use does not constitute a limitation on the use of the present invention.

When the operation is performed under an endoscope, firstly, the suture 1 with the barbs 2 is sequentially arranged among the 2 arms 8 on the plurality of clamping units 4, then the 2 arms 8 are combined and fixed with tissues around the wound 5, the hole-shaped structure 6 or the slit structure 7 is formed among the 2 arms 8, the suture 1 is positioned among the hole-shaped structure 6 or the slit structure 7, after the last clamping unit 4 is fixed, the suture 1 is tensioned, the wound 5 is closed, and as the plurality of barbs 2 are distributed on the suture 1, each clamping unit 4 can be clamped with the barb 2 adjacent to the suture 1, so that the suture 1 has the characteristic that the suture can only pass through the clamping units 4 in one direction, the suture 1 is not easy to loosen, and the wound 5 is good in tightening and fixing effects.

After last clamping unit 4 is fixed, taut stylolite 1, wound 5 is closed, and end barb has can fix wound 5 and prevent that the stylolite from taking off, and on this basis, accessible is tied a knot, is set up modes such as solid fixed ring 3 and further fixes stylolite 1, avoids the pine to take off.

the utility model discloses a device can be when sewing up the wound, all can conveniently fix the centre gripping unit around the wound of arbitrary size, and not injured mouthful size, the restriction of kind, the stylolite with barb pass the centre gripping unit after, when taut stylolite, the barb can block on the centre gripping unit, and the wound can not pine take off, avoids straining the stylolite repeatedly, improves operation efficiency.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
