Abstract
Disclosed is a bile duct anastomosis stent, comprising a stent main body made of degradable material which is acceptable by people. The stent main body takes the shape of a tube and has a diameter which is suitable for putting in a bile duct. Each of the two sides of the outer surface of the main body is provided with a circle of protuberance for fixing the pouch line knots at the broken ends of the bile duct. The bile duct anastomosis stent has the advantages that the bile duct anastomosis stent is easy to operate, quick, short in anastomosis time and low in cost and has no complicating disease after the operation.
Description
(1) technical field
The present invention relates to a kind of support that bile duct coincide that is used for, can simplify bile duct and coincide, improve the safety that bile duct coincide.
(2) technical background
At present, the first phase reparation of the cross-section back of bile duct mainly adopts the gallbladder intestinal to coincide, or the method for bile duct end to end anastomosis T Tube Drain.These two kinds of methods all will use silk thread or absorbable thread to sew up by pin, operates more loaded down with trivial detailsly, and the identical time is long.And the identical meeting of gallbladder intestinal changes normal physiological passage, complication such as postoperative generation bile reflux.Bile duct end to end anastomosis T Tube Drain postoperative, the T pipe needs long-time the indwelling, has brought inconvenience to patient's life.In addition, adopt this dual mode and apparatus to repair after, the incidence rate of complication such as anastomotic leakage, anastomotic stricture is higher.
(3) summary of the invention
The present invention will solve the deficiency that existing bile duct coincide, provide a kind of processing ease, fast, the time that coincide is short, post-operative complication is few, and the support that coincide of cheap bile duct.
Bile-duct anastomosis bracket of the present invention: it is characterized in that comprising one and use the rack body that human body can be accepted and degradation material is made, rack body in a tubular form, have adaptation and insert the diameter of bile duct, the both sides of this external surface respectively have a circle to be used for fixing the projection of the purse wire tieing of the bile duct broken ends of fractured bone.
When coincideing, do purse string suture respectively at the both sides bile duct broken ends of fractured bone earlier, then support is put into both sides bile duct intracavity, in projection 2 inboards purse wire is tied a knot respectively, the two side bile duct broken ends of fractured bone are fixed on mid-stent 1, and make both sides broken ends of fractured bone contact, finish bile duct and coincide.Behind the anastomotic healing, support is degraded gradually, and the degraded composition excretes by biliary tract, and no foreign body is residual in the biliary tract.In the anastomotic stoma growth healing, support can be with anastomotic stoma and bile isolation, has avoided contacting of bile and anastomotic stoma.Help anastomotic stoma growth healing, reduce 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 sew up knotting by pin, the identical time obviously shortens.Because the support manufacturing process is simple, the prices of raw and semifnished materials are more cheap, 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 identical operation of bile duct, shortens the time of coincideing, and the low cost of manufacture of support can reduce surgery cost.2, support is isolated bile and anastomotic stoma tissue, has avoided contacting of bile and anastomotic stoma, helps the growth healing of anastomotic stoma, the incidence rate of reduction anastomotic fistula.3, support has supporting role to anastomotic stoma, can prevent anastomotic stricture.4, after support coincide, do not change the biliary tract structure, avoided the generation of complication such as biliary tract retrograde infection; Do not keep somewhere the T pipe, patient is influenced little.5, support is the degradation material manufacturing, the degraded of anastomotic healing after-poppet, and the degraded composition excretes with biliary tract, and no foreign body is residual in the back biliary tract that therefore coincide.

(5) specific embodiment
With reference to accompanying drawing:
Bile-duct anastomosis bracket of the present invention comprises that is used the rack body 1 that human body can be accepted and degradation material is made, rack body 1 in a tubular form, have adaptation and insert the diameter of bile duct, the both sides of body 1 outer surface respectively have a circle to be used for fixing the projection 2 of the purse wire tieing of the bile duct broken ends of fractured bone.
Rack body 1 adopts human body can accept and degradable material, for example polylactic acid.The diameter of body 1 can specifically be selected according to the thickness of human body bile duct, has multiple model.
When coincideing, do purse string suture respectively at the both sides bile duct broken ends of fractured bone earlier, then support is put into both sides bile duct intracavity, in projection 2 inboards purse wire is tied a knot respectively, the two side bile duct broken ends of fractured bone are fixed on rack body 1 middle part, and make both sides broken ends of fractured bone contact, finish bile duct and coincide.Behind the anastomotic healing, support is degraded gradually, and the degraded composition excretes by biliary tract, and no foreign body is residual in the biliary tract.In the anastomotic stoma growth course, support can be isolated anastomotic stoma and bile, has avoided contacting of bile and anastomotic stoma, helps anastomotic stoma growth healing, the incidence rate of reduction 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 sew up knotting by pin, the identical time obviously shortens.Because the support manufacturing process is simple, the prices of raw and semifnished materials are more cheap, 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.
Claims (1)
1. bile-duct anastomosis bracket comprises that is used the rack body that human body can be accepted and degradation material is made, and rack body has the diameter that is suitable for inserting bile duct in a tubular form; It is characterized in that: the both sides of this external surface respectively have a circle to be used for fixing the purse wire tab protrusions of the bile duct broken ends of fractured bone; Every circle projection has distance with the outer end of rack body respectively, body part between described projection and the outer end forms and is suitable for inserting the extension of bile duct, and the gradient of the inboard of described projection is greater than the gradient in the outside, the step of the fixing described purse wire joint of formation.
