Described pancreatic tissue annular binding is pricked fixing band and can be adopted polyethylene or degradation material to make, the width that the pancreatic tissue annular binding is pricked fixing band is preferably 2~6mm, thickness is preferably 0.2~5mm, and length is preferably 4~10cm (individual instances according to patient during use is cut out).The height of strip fin is preferably 1~2mm, the best 1~3mm of the length of crochet hook.
Preferably be provided with at least one ring through hole on the described intestinal upset retainer ring, or preferably be provided with a ring spike thing in intestinal upset retainer ring inboard, the spike thing preferably perpendicular to intestinal upset retainer ring medial surface, prick by the seam of being convenient to small intestinal.
Described flexible fastening ring preferably adopts rubber ring, falope ring or teething ring etc., and rubber ring is acrylonitrile-butadiene rubber ring etc. for example, and the height of intestinal upset retainer ring can be 2~5mm, and thickness can be 1~1.5mm, and diameter is 3~5cm, and the thickness of bulge loop is preferably 1~3mm.
Because the design that this utility model adopts the binding sleeve type to coincide, only be provided with the pancreatic tissue annular binding and prick fixing band and intestinal upset retainer ring, it is shoestring that the pancreatic tissue annular binding is pricked fixing band, the upper surface of shoestring is provided with the strip fin, and a side of strip fin is the plane, and the shoestring lower surface is provided with row's crochet hook again; In addition, intestinal upset retainer ring is the flexible fastening ring, has extended bulge loop in the bottom inside of intestinal upset retainer ring, so bulge loop can be kissed smoothly with the strip fin of pancreatic tissue annular binding bundle fixing band and connects.
Because it is shoestring that the pancreatic tissue annular binding is pricked fixing band, earlier the pancreatic tissue annular binding is pricked fixing band when therefore performing the operation and be bound in pancreas broken ends of fractured bone tissue, therefore can easily the pancreatic tissue annular binding be pricked the pancreas broken ends of fractured bone tissue that fixing band is banded in patient according to patient's individual instances with suitable elasticity.
Be provided with 1~3 row's crochet hook owing to prick the shoestring lower surface of fixing band in the pancreatic tissue annular binding, on intestinal upset retainer ring bottom inside, be provided with bulge loop again, so the pancreatic tissue annular binding is pricked more identical, reliable, the safety of being connected of fixing band, pancreas broken ends of fractured bone tissue, small intestinal and intestinal upset retainer ring.
This shows that this utility model can significantly reduce surgery Pancreaticoduodenectomy postoperative complication,, complication can be reduced to 0 as long as operation is correct.In addition, operation technique is simple, can save operating time significantly, generally can save operating time 20~30min.Simultaneously can reduce surgery cost significantly.
