Described first group of anastomosis staple and second group of anastomosis staple can be linear arrangement, and described linear arrangement can adopt and be arranged in parallel or longitudinal arrangement; Described first group of anastomosis staple and second group of anastomosis staple can adopt plug-in type.
Compared with existing sandwich style circular stapler, the utlity model has following outstanding feature:
1. adopt oval nail bit, oval nail bin and corresponding first group of anastomosis staple and second group of anastomosis staple;
2. adopt anastomat nail bit in identical forward and backward double-turning-cover technology; The top of oval nail bit adopts and is flexibly connected with nail bit bar, and therefore, before anastomat coincide, the top major axis of oval nail bit and the angle of nail bit bar are greater than 90 °, and the top minor axis of oval nail bit and the angle of nail bit bar equal 90 °; In coincideing, before percussion, the top of oval nail bit is vertical with nail bit bar; After coincideing, after percussion, on the top of oval nail bit, turn over, the top major axis of oval nail bit and the angle of nail bit bar are greater than 90 °.
3. adopt the mode that adds reinforced membrane and lower reinforced membrane on oval nail bit, oval nail bin surface, make reinforced membrane, intestinal wall and lower reinforced membrane form sandwich structure;
4. double anastomosis staple adopts outer nail to be longer than the not isometric technology of interior nail.
Can obtain thus following corresponding function:
1. oval tubular anastomat, adopt simultaneously coincide before and after double-turning-cover technology can solve " sandwich style " circular stapler nail bit before anastomosis procedures kind is coincide and be difficult for placing in intestinal and the problems such as rear nail bit is not drawn out easily of coincideing.
2. oval tubular anastomat adopts the outer platoon leader of anastomosis staple can solve the identical front and back of " sandwich style " anastomat in interior nail and causes the problems such as the local intestinal wall ischemia of anastomotic stoma (disturbance of blood circulation).
3. oval tubular anastomat adopts " sandwich " formula structure can solve identical rear Anastomotic bleeding, anastomotic leakage is residual three problems of anastomotic stoma anastomosis staple.

The specific embodiment
Referring to Fig. 1～5, this utility model embodiment is provided with flexible handle 1, device body 2, oval nail bit 3, oval nail bin 4, upper reinforced membrane 5, lower reinforced membrane 6 and nail bit bar 7; The front end of device body 2 is connected with oval nail bit 3, and the rear end of device body 2 is connected with flexible handle 1, and described oval nail bin 4 is provided with oval nail kit 41, oval nail seat 42, first group of anastomosis staple 43 and second group of anastomosis staple 44; The top of described oval nail bit 3 is flexibly connected with nail bit bar 7, the top major axis 31 of described oval nail bit 3 is 90 ° with the angle of nail bit bar 7, the top minor axis 32 of described oval nail bit 3 is 90 ° with the angle of nail bit bar 7, the length of described first group of anastomosis staple 43 is 70% of second group of anastomosis staple 44 length, described upper reinforced membrane 5 is located at oval nail kit 41 surfaces, described lower reinforced membrane 6 is located at oval nail seat 42 surfaces, and upper reinforced membrane 5, intestinal wall 8 and lower reinforced membrane 6 form sandwich structure; Oval nail seat 42 is associated with oval nail kit 41 operability, and oval nail seat 42 is connected with movable the coincideing of oval nail kit 41.
Described upper reinforced membrane 5 and lower reinforced membrane 6 all adopt elliptical annular film; The ring width of described elliptical annular film is 2mm, and the thickness of elliptical annular film can be 0.5mm.Described upper reinforced membrane 5 is established two-layer.
Described upper reinforced membrane 5 and lower reinforced membrane 6 all adopt silica gel or poly-lactonaphthol class.
Described first group of anastomosis staple 43 and second group of anastomosis staple 44 adopt and are arranged in parallel or longitudinal arrangement; Described first group of anastomosis staple 43 and second group of anastomosis staple 44 adopt plug-in type.
Fig. 6 provides " sandwich " organizational structure design sketch forming after the anastomosis operation stitching of this utility model embodiment.In Fig. 6, when operation, upper reinforced membrane 5 can be arranged in the groove of oval nail anvil 3 (corresponding to the nail position of anastomosis staple stitching), separately lower reinforced membrane 6 is arranged in the groove of oval nail bin 4 (corresponding to the nail position of anastomosis staple stitching).Because the surface of the surface at oval nail bit 3 and oval nail bin 4 is equipped with membranoid substance, therefore make two membranoid substances after stitching (upper reinforced membrane 5 and lower reinforced membrane 6) by first group of anastomosis staple 43 and second group of anastomosis staple 44 stitching the surface at intestinal wall 8, after stitching, form the sandwich structure of reinforced membrane 6 under upper reinforced membrane 5+ intestinal wall 8+, make the closure after intestinal wall 8 stitchings better, stressed more balanced, in surgical operation, can effectively reduce alimentary tract anastomosis stomatorrhagia, tear, the phenomenon such as fistula of operative incision (leakage) and anastomotic stoma tangent plane oozing of blood.First group of anastomosis staple 43 and second group of anastomosis staple 44 can come off with upper reinforced membrane 5 and lower reinforced membrane 6, reach the residual object of anastomotic stoma foreign, and the possibility of narrow and inflammation occurs minimizing anastomotic stoma.
This utility model has structurally been done important improvement, not only overcome existing " sandwich " formula anastomat, after coincideing, nail bit is difficult for taking out and two problems of anastomotic stoma disturbance of blood circulation, and can reach the deficiency that prevents the circular staplers such as anastomotic leakage, Anastomotic bleeding and anastomotic stoma foreign body be residual, therefore this utility model, improving alimentary tract anastomosis, avoids the aspects such as intestinal tract complication to have outstanding technique effect.
