Studies show that, though the reason of pancreas leakage takes place the identical method of tradition easily is many-sided, comprise sex, age, nutriture, liver function; diseased region; lesion nature; residual pancreas quality; main pancreatic duct diameter; pancreatic secretion amount; pancreas intestinal methods of anastomosis; the placement of pancreatic juice drainage tube and biliary drainage pipe; application of biogum and somatostatin or the like; but main still because existing complexity of pancreas intestinal anastomosis own and imperfection; very easily make a fault or defective is easily torn pancreatic tissue when sewing up knotting; pancreas is because of too crisp soft or sew up very few isolating; anastomotic stoma pin hole or gap seepage; the pancreas intestinal is inserted in not congruent.
In order to reduce the generation that pancreas leaks, the identical method that many improvement occurred, as the pancreas stomach coincide, the end-to-side anastomosis of ductus pancreaticus jejunum mucosa, pancreas jejunum cluster coincide etc., but these methods are not broken away from the framework of traditional operation basically, complication also therefore and obviously reduces.This shows that the reliability of improving anastomosis is the successful key of operation.Up to now, do not see the report of the medical apparatus and instruments that is useful on auxiliary pancreas intestinal anastomosis operation.
Summary of the invention
At the shortcoming of prior art, the invention provides a kind of absorbable pancreas intestine anastomat, be that raw material is made with polyglycolic acid (polyglycolic acid), be used to replace the identical operation of complicated craft, simplify operating procedure.
Technical scheme of the present invention is: a kind of pancreas intestine anastomat, shape is elliptical cylinder, described pancreas intestine anastomat is that raw material is made by polyglycolic acid, on the inwall of described one of them end face of elliptical cylinder, be provided with lobe, on the sidewall of described elliptical cylinder, be provided with a plurality of through holes, described a plurality of through hole is network, is provided with prominent point at the infall of grid, and also is provided with the contraction structure that the internal diameter that makes described elliptical cylinder diminishes on described elliptical cylinder.
Described elliptical cylinder is formed by described contraction structure connection by two and half cylindrical shells, described contraction structure is the step buckle and the draw-in groove of mutual corresponding matching, described step buckle and draw-in groove are located at respectively on two end faces of half cylinder lateral wall, leave the space between the adjacent step buckle, leave the space between the adjacent draw-in groove.
Polyglycolic acid (polyglycolic acid) is the biomaterial for medical purpose that is widely used in recent years in the operation, and it has following characteristics: (1) excellent biological compatibility and degradability, and tissue reaction is minimum, to the nontoxic no thermal source of human body; (2) the degraded and absorbed process is simple hydrolytic process, finally generates water and carbon dioxide; (3) implant into body began to be absorbed after 15 days, was absorbed fully in 60-90 days; (4) physics and mechanics quality stable, plasticity are easy to machine-shaping well, also are convenient to sterilization.
In operation, pancreas intestine anastomat is entangled the broken ends of fractured bone of the identical jejunum of confession, with the mesojejunum blood vessel by drawing between buckle, with the slight calcination jejunum of electric knife end mucous layer, the jejunum that reuse is with anastomat entangles pancreas cervical region stump, utilize the locking of contraction structure appropriateness, the lobe of the inwall of pancreas intestine anastomat end face tightens up the pancreas appropriateness, thereby has connected pancreas and intestinal portion.The network of pancreas intestine anastomat is avoided guaranteeing enough blood supplies because of the local organization ischemic necrosis that adopts stronger structures such as barrel shaped structure to cause.Because pancreas intestine anastomat is that raw material is made with the polyglycolic acid, can be by the human body degraded and absorbed.In operation, adopt pancreas intestine anastomat of the present invention, not only simplified operating procedure greatly, greatly alleviate operation strength, shorten operating time (expectation can foreshorten to 5-10 minute by 50-60 minute in the past) significantly, and be difficult for causing defective or error in the operation, can avoid manual suture a series of insuperably difficulties of institute and shortcoming, be expected to reduce or stop pancreas and leak incidence rate.
