Abstract

The utility model relates to a colonic binding type anastomosed supporting stand, which comprises a through tube which can be accepted by human bodies and is made of degradable material, wherein the center portion of the through tube takes tube shape, and both ends are provided with trumpet-shaped openings which are gradually enlarged, and a groove is arranged between the tubular center portion and the trumpet-shaped openings. The supporting stand is arranged in an intestinal cavity when in anastomosis, a colon is fixed on the supporting stand by a line on the groove, both ends of the colon contact on the center of the longitudinal shaft of the supporting stand to grow and heal, and colonic anastomosis is achieved. The colonic binding type anastomosed supporting stand can simplify operation, shorten operation time, and reduce the occurrence of the leakage of an anastomotic and narrow anastomotic.

Description

Colon bundling type anastomotic bracket

(1) technical field

This utility model relates to a kind of support that colon coincide that is used for, and can simplify colon and coincide, and improves the safety that colon coincide.

(2) technical background

At present, the colon method of coincideing mainly comprises manual suture coincide two kinds of method, the identical methods of anastomat.The manual suture method of coincideing is time-honored identical method, adopts silk thread or absorbable thread to finish by hand, operates more loaded down with trivial details, the time of coincideing is long, certain anastomotic leakage incidence rate is arranged, but this identical method cost is low, especially is still the identical method of topmost colon in the economically less developed region.It is identical that the anastomat method of coincideing is to use anastomat to finish colon, and identical method is simple, and the time that coincide is short, but anastomat price height will leave metallic foreign body in the pneumoretroperitoneum that coincide throughout one's life, and need open anastomat insertion mouth in addition, increases wound.Because colonic contents all directly contacts complication rate height such as anastomotic leakage in these identical methods with anastomotic stoma.

(3) summary of the invention

This utility model will solve the above-mentioned deficiency of existing colon coinciding machine, this utility model provide a kind of simplification coincide operation, shorten the time of coincideing, reduce post-operative complication, and support low cost of manufacture, colon anastomosis bracket applied widely.

Colon bundling type anastomotic bracket described in the utility model, it is characterized in that: comprise the siphunculus that a human body can be accepted and degradation material is made, the middle part of described siphunculus in a tubular form, two ends are the horn-like opening that enlarges gradually, described tubulose middle part is fluted with the connecting portion of horn-like opening.

Support is placed in the enteric cavity when coincideing, and colon is fixed on the support with line at groove, and colon two broken ends of fractured bone are in the contact of support longitudinal axis center, and the growth healing realizes that colon coincide.Behind the anastomotic healing, support is degraded gradually, and the degraded composition excretes by intestinal, and it is residual that intraperitoneal does not have foreign body.In the anastomotic healing process, support is isolated anastomotic stoma and colonic contents, helps anastomotic stoma growth healing, reduces the incidence rate of anastomotic leakage; Support has supporting role to anastomotic stoma, can prevent anastomotic stricture.Because fixing only use of support tied up for twice, do not need as manual suture, intestinal tube to be pursued pin and sew up knotting, do not make purse string suture and do little otch near the intestinal wall anastomotic stoma to put into anastomat at intestinal two broken ends of fractured bone when also not needing to coincide as anastomat, the identical time obviously shortens.This support can be used for anastomotic leakage and colonic perforation after the colocolic anastomosis, and support is put into enteric cavity, and leak (or perforation place) the two ends intestinal wall that coincide is banded on the support, makes the enteric cavity sealing.Because the support manufacturing process is simple, the prices of raw and semifnished materials are more cheap, and the price of support is starkly lower than anastomat, and the whole surgery expense is near the identical method of manual suture.

The beneficial effects of the utility model: 1, support can obviously be simplified the identical operation of colon, shortens the time of coincideing, and the low cost of manufacture of support can reduce surgery cost.2, support tube can be isolated colonic contents and anastomotic stoma tissue, helps the growth healing of anastomotic stoma, reduces the incidence rate of anastomotic fistula.3, this support fixedly the position of intestinal wall away from broken-hearted end, the situation that anastomotic stoma is torn easily when having avoided sewing up on the broken ends of fractured bone intestinal tube wall of edema, fragility, and the blood between intestinal tube fixed position and the healing position is for still keeping, the blood of healed surface is for unaffected, so the growth of anastomotic stoma healing obviously is better than existing identical method.4, support can realize safely under special environments such as no intestinal preparation, intestinal leakage, abdominal cavity infection that colon coincide, avoided the existing method of the coincideing first phase intestine fistulization of to go ahead of the rest in these cases, the situation that the capable again intestinal of secondary operation coincide, make patient avoid the second operation misery, shorten whole treatment cycle greatly, reduced the consumption of medical resource.5, when anastomotic leakage or intestinal perforation, support can realize safely that first phase repairs, and the incidence rate that previous methods row first phase leaks after repairing once more is high, can only go the first phase fistulation, and the second stage of intestinal coincide.6, support is a degradation material, the degraded of anastomotic healing after-poppet, and the degraded composition excretes with intestinal, and no foreign body is residual in the pneumoretroperitoneum that therefore coincide.

(5) specific embodiment

Colon bundling type anastomotic bracket described in the utility model, comprise the siphunculus that a human body can be accepted and degradation material is made, the middle part of described siphunculus in a tubular form, two ends are flared horn-like opening gradually, described tubulose middle part is fluted with the connecting portion of horn-like opening.

The human body that this utility model adopts can be accepted and degradation material, for example polylactic acid.

Present embodiment is only for the explanation the technical solution of the utility model; but not to the restriction of protection domain of the present utility model; those of ordinary skill in the art; under the situation that does not break away from design scope of the present utility model, can also make various variations; all equivalent technical solutions also belong to scope of the present utility model, and protection domain of the present utility model should be defined by the claims.

Claims
