Description
Technical field
This utility model relates to a kind of Cholangio-jejunostomy device, specifically a kind of Cholangio-jejunostomy device nail supporting base.
Background technology
When bile duct causes obstruction because of reasons such as Stone obstruction, cicatricial stenosis, tumors, the bile duct of obstructive position nearside and intestines usually directly connect by surgeon, make bile can flow directly to enteral through this interface, just look like after a blocking barrier of road, in the middle of road, separately open a sidewalk the same, this operation is just called biliary enteric anastomosis.
Anastomat be the alternative traditional-handwork seam that medically uses in biliary enteric anastomosis and equipment, the operation principle of anastomat is similar to the stapler used in our daily life, but it is utilize multiple anastomosis staple to sew up bodily tissue in an anastomosis procedure.The anastomat used clinically at present has skin stapler, digestive tract circular staplers, hernia anastomat and lung stapler etc.
For biliary enteric anastomosis, its specific practice has many kinds, and what the most often do at ordinary times is choledochojejunostomy, choledochoduodenostomy and Oddi's sphincter otomy three kinds.
(1) choledochojejunostomy
This method is exactly common bile duct and jejunum (epimere of small intestinal) are done " Y " shape coincide, operation technique more complicated, time-consuming.But this operation makes choledoch-ly to deposit below one section of longer jejunum and be used for specially carrying bile, chyme adverse current through longer distance, therefore causes the chance of biliary tract infection less to common bile duct domestic demand, and this is the great advantage of this operation.Choledochojejunostomy is mainly applicable to common bile duct the narrow patient of (traumatic or struvite) and the patient of calculus of intrahepatic duct.The patient that distal common bile duct cancerous protuberance can not be ectomed, also can do this operation sometimes.
(2) choledochoduodenostomy
This operation is directly connect common bile duct and duodenum first paragraph, and Post operation bile just successfully enters duodenum by anastomotic stoma.Common bile duct and duodenum lean on very near, therefore the operation of this operation is comparatively simple.After choledochoduodenostomy, because of without sphincteral effect, food is through duodenum, enter by anastomotic stoma in common bile duct, have the possibility causing " ascending " common bile duct to infect, as long as but in fact anastomotic stoma is sufficiently large, food is entered easily, out also easy, cause the chance of biliary tract infection just less, Post operation also can obtain good effect.The indication of operation is basic identical with choledochojejunostomy.
(3) Oddi's sphincter otomy
This operation method is cut by duodenum, finds choledoch-opening part nipple, cut off by Oddi's sphincter.Sphincter is annular muscle, just can not close after cutting off again, and the traffic between common bile duct and duodenum is just unobstructed.This operation is mainly applicable to the narrow chronic pancreatitis patient of Oddi's sphincter, and calculus gets lodged in distal common bile duct and also can make this operation taking-up calculus sometimes.The anatomical structure at Oddi's sphincter position is very meticulous, also has the opening of ductus pancreaticus simultaneously, therefore the operation more complicated of this operation, Post operation can with certain complication sometimes, and practical application is general not as two kinds of operations above.
Anastomosis procedure process about anastomat is as follows:
If application number CN201210129787.2, application publication number are CN102755179A; Or, application number CN201320099707.3, notification number is CN203122504U; Middle announcement such,
The first step, cuts open one of them pipeline to be anastomosed, is inserted by circular nail supporting base (being similar to stapler base), is passed by center-pole (play a part position check and correction and be fixedly connected with) and will ligation be organized on center-pole around groove place from groove;
Second step, by inserting in this pipeline cavity volume of circular nail storehouse sleeve (be similar to stapler and go out nail bin), wears tartar and passes from the inwall of pipeline by device;
3rd step, wears tartar and docks with center-pole fixing by device, by action such as adjustment rotations grade, make circular nail storehouse sleeve corresponding to circular nail storehouse sleeve position (groove be similar on the nail mouth of stapler and stapler base is corresponding);
4th step, arming, percussion circular staple, pipeline in second step and the pipeline in the first step are nailed together, anastomosis staple to embed in two management organizations to be anastomosed and will organize nail joint together as staple, simultaneously, tissue in anastomosis staple array circle is cut off, and realizes two pipeline intercommunications;
5th step, by insert in two pipelines circular nail supporting base, the tissue of cut-out, circular nail storehouse sleeve, stapler main body pull-out gently together, so far two pipelines to be anastomosed have coupled together.
At present, circular staplers is very restricted in using in Cholangio-jejunostomy, the reason of restriction is: choledoch-diameter is thinner, and anastomotic stoma can not be too little, normal choledoch-diameter is about in 8mm(surgical operation the expansion common bile duct seldom having diameter at 20mm), the nail supporting base of conventional circular anastomat is difficult to insert, and the center-pole of nail supporting base must be basically perpendicular to choledoch-axis when doing Cholangio-jejunostomy, because anastomotic stoma can not be enough large, therefore, circular nail supporting base is difficult to put into common bile duct due to the restriction of thickness and width; And, because biliary tract wall has enough elasticity unlike intestinal wall, after nail supporting base is inserted, in time in the biliary tract wall ligation to center-pole at groove place, is had too much biliary tract wall draw close to center-pole, and the biliary tract wall also out-of-flatness after ligation, too much biliary tract wall can be excised like this after coincideing, easy damage nutrient artery, there is the complication such as hemorrhage, and due to the shape when biliary tract wall out-of-flatness after ligation causes postoperative biliary tract wall can not maintain cutting preferably, coincide of low quality, easily anastomotic stenosis after surgery occurs.
Number of patent application is 201320099707.3, notification number is 203122504U, denomination of invention is Cholangio-jejunostomy device, disclose a kind of Cholangio-jejunostomy device, the section of its nail supporting base is made up of two semicircles and a rectangle, and the outer shape in school playground runway, center-pole has the He Erbao for ligation biliary tract wall, not easily put into solve the young nail supporting base of biliary tract, the problem of biliary tract wall polishing after cutting.But this utility model scheme brings again new problem, first: this nail supporting base in school playground runway profile, because biliary tract bore is little, the end face of nail supporting base is again the maximum place of nail supporting base circumferential area, is difficult to nail supporting base to insert biliary tract pipe completely.Second: even if insert biliary tract pipe, being also difficult to by rotating adjustment direction again, clinical operation, sometimes needing repeatedly to rotate nail supporting base, finding most suitable position, being basically perpendicular to choledoch-axis to make the center-pole of nail supporting base.3rd: although be provided with the He Erbao of ligation biliary tract wall on center-pole, but because common bile duct is thinner, nail supporting base is difficult to insert common bile duct, even if insert common bile duct, nail supporting base is also almost at choledoch-opening part, that is, plan does not have unnecessary choledochal wall for ligation, and therefore common bile duct ligation is also just very difficult.
Summary of the invention
In order to overcome above-mentioned technical problem, the utility model proposes a kind of Cholangio-jejunostomy device nail supporting base, comprise nail supporting base base, nail supporting base contact surface, nail supporting base contact surface be provided with and doublely support nail groove group, the middle part of nail supporting base contact surface is provided with center-pole, this utility model Cholangio-jejunostomy device nail supporting base is put unlike the prior art and is: described nail supporting base base is Semen Jujubae shape, nail supporting base contact surface is positioned at the top of Semen Jujubae shape nail supporting base base circumference maximum section, and nail supporting base contact surface diameter is less than the diameter of nail supporting base base circumference maximum section.Described nail supporting base contact surface is positioned at the top 3-8mm of nail supporting base base circumference maximum section.The thickness of described nail supporting base base is greater than the diameter of nail supporting base contact surface.
Beneficial effect: the first, because nail supporting base base is Semen Jujubae shape, for the common bile duct that bore is less, the base of Semen Jujubae shape more easily inserts common bile duct.Second, the nail supporting base of this circular cross-section is because bottom is Fructus Jujubae shape recklessly, therefore when inserting that after common bile duct, position is not good, be easy to rotate adjustment, and, thickness due to nail supporting base base is greater than the diameter of nail supporting base contact surface, and make hardly with adjustment, the center-pole of nail supporting base just can perpendicular to choledoch-axis.3rd, because nail supporting base contact surface is positioned at the top of Semen Jujubae shape nail supporting base base circumference maximum section, nail supporting base contact surface diameter is less than the diameter of nail supporting base base circumference maximum section, image a bit says it is that nail supporting base contact surface is positioned at half Fructus Jujubae top recklessly, such setting, because ligation place is strutted by nail supporting base base, the choledochal wall be near nail supporting base contact surface is in contraction state just, and common bile duct ligation becomes easier.When described nail supporting base contact surface is positioned at the top 3-8mm of nail supporting base base circumference maximum section, biliary tract wall is more smooth, and postoperative biliary tract wall energy maintains shape during cutting preferably, and quality of coincideing is high.
