Abstract
The invention relates to a gastrointestinal anastomosis stent, comprising a stent main body made of degradable material which is acceptable by people. The middle of the stent main body is tubular, and two ends of the stent main body are open and increase gradually like a trumpet; one opening is big and the other opening is small; the opening at the big end is in a shape and a size which are suitable for the lumen of the stomach; and the opening at the small end is in a shape and a size which are suitable for the lumen of the intestine. The gastrointestinal anastomosis stent can simplify anastomosis process, shorten anastomosis time and reduce complicating diseases after the operation, and the stend is low in cost and wide in application range.
Description
(1) technical field
The present invention relates to a kind of support that is used for gastrointestinal anastomosis, can simplify gastrointestinal anastomosis, improve the safety of gastrointestinal anastomosis.
(2) technical background
At present, the method for gastrointestinal anastomosis mainly comprises manual suture coincide two kinds of the methods of method, anastomat of coincideing.The manual suture method of coincideing is time-honored identical method, adopts silk thread or absorbable thread manual suture to finish, and operates more loaded down with trivial details, the time of coincideing is long, the incidence rate that certain anastomotic stoma complication is arranged, but this identical method cost is low, is still topmost gastrointestinal anastomosis method in the economically less developed region.The anastomat method of coincideing is to use anastomat to finish gastrointestinal anastomosis, and the method for coincideing 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.Because these identical methods and equipment itself exist not enough, complication such as anastomotic leakage, anastomotic stricture are difficult to avoid.
(3) summary of the invention
The present invention will solve the deficiency of above gastrointestinal anastomosis equipment, provides a kind of energy to simplify identical operation, shortens the time of coincideing, minimizing post-operative complication and support low cost of manufacture, stomach and intestine anastomosis bracket applied widely.
Stomach and intestine anastomosis bracket of the present invention, it is characterized in that: comprise that one can be accepted and the rack body made of degradation material with human body, the middle part of rack body in a tubular form, two ends are the horn-like opening that increases gradually, one side opening is big, one side opening is little, bigger open-ended shape and size with adaptation gastral cavity, less open-ended shape and size with adaptation enteric cavity.
When coincideing, earlier do purse string suture respectively at harmonization of the stomach intestinal tube opening part, the open-ended gastral cavity of putting into that then will be bigger, the purse wire knotting, coat of the stomach is fixed on mid-stent, again with the less open-ended enteric cavity of putting into, the purse wire knotting, intestinal wall is fixed on mid-stent, and coat of the stomach contacts in mid-stent with the intestinal wall broken ends of fractured bone, finishes gastrointestinal anastomosis.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 gastrointestinal 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 this identical method only needs twice purse string suture of row, do not need as manual suture, to pursue pin and sew up knotting, the identical time obviously shortens.Because the support manufacturing process is simple, the prices of raw and semifnished materials are cheap, and the price of support is starkly lower than anastomat, and the whole surgery expense is near the identical method of manual suture.
Beneficial effect of the present invention: 1, support can obviously be simplified the gastrointestinal anastomosis operation, shortens the time of coincideing; The low cost of manufacture of support can reduce surgery cost.2, support is isolated gastrointestinal contents and anastomotic stoma tissue, helps the growth healing of anastomotic stoma, reduces the incidence rate of anastomotic fistula.3, support tube has supporting role to anastomotic stoma, can prevent anastomotic stricture.4, support is the degradation material manufacturing, 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
Stomach and intestine anastomosis bracket of the present invention, comprise that one can be accepted and the rack body made of degradation material with human body, the middle part 1 of rack body in a tubular form, two ends are that horn-like opening mouth one end opening that increases gradually is big, one end opening is little, bigger open-ended 2 have the shape and size that adapt to the stomach inner chamber, and less open-ended 3 have the shape and size that adapt to enteric cavity.
The human body that the present invention adopts can be accepted and degradation material, for example polylactic acid.
When coincideing, earlier do purse string suture respectively at harmonization of the stomach intestinal tube opening part, end 2 openings that then will be bigger are put into gastral cavity, purse wire knotting, coat of the stomach is fixed on mid-stent, puts into enteric cavity with less open-ended 3 again, the purse wire knotting, intestinal wall is fixed on mid-stent 1, and coat of the stomach contacts in mid-stent with the intestinal wall broken ends of fractured bone, finishes gastrointestinal anastomosis.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 gastrointestinal 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 this methods of anastomosis only needs twice purse string suture of row, do not need as manual suture, to pursue pin and sew up knotting, the identical time obviously shortens.Because the support manufacturing process is simple, the prices of raw and semifnished materials are cheap, and the price of support is starkly lower than anastomat, and the whole surgery expense is near the identical method of manual suture.
Present embodiment is only for explanation technical scheme of the present invention; but not to the restriction of protection scope of the present invention; those of ordinary skill in the art; under the situation that does not break away from design scope of the present invention, can also make various variations; all equivalent technical solutions also belong to scope of the present invention, and protection scope of the present invention should be defined by the claims.
