Description
Technical field
The present invention relates to a kind of surgical apparatus, especially relate to the not isometric anastomosis staple of a kind of ellipse and renovate circular stapler.
Background technology
At present, in surgical operation the application of circular stapler very extensive, used decades, but this type of anastomat in clinical use, there is anastomotic leakage, Anastomotic bleeding always and coincide after the problems such as anastomosis staple is residual.The applicant discloses a kind of sandwich stapler-type digestive tract anastomosis cutting closer for suture tissue in Chinese patent CN102813540A.The identical nail kit and the membranoid substance that are provided with flexible handle, are connected from the extended device body of handle end, with device body end; Described identical nail kit is provided with nail kit, nail seat, first group of anastomosis staple and second group of anastomosis staple, and the length of described first group of anastomosis staple is 5%～95% of second group of anastomosis staple length; Described membranoid substance directly contacts nail kit surface; Described membranoid substance is established upper strata membranoid substance and lower floor's membranoid substance, and described upper strata membranoid substance directly contacts nail kit surface, the direct contact stud seating face of described lower floor membranoid substance, and upper strata membranoid substance, intestinal wall and lower floor's membranoid substance form sandwich structure.Although this sandwich stapler-type digestive tract anastomosis cutting closer is obtained better effects in above-mentioned three problems of solution, in animal experiment, find its two problems below existence:
1. because the dilatability of coincideing after blooming lowers, after therefore coincideing, nail bit (seat) is difficult for taking out from intestinal.
2. when identical, due to dynamics, easily grasp is improper, therefore easily causes the intestinal wall disturbance of blood circulation necrosis of anastomotic stoma region.
Summary of the invention
The object of the invention is to for the existing deficiency of above-mentioned sandwich stapler-type digestive tract anastomosis cutting closer, provide the not isometric anastomosis staple of a kind of improved ellipse to renovate circular stapler.
The present invention is provided with flexible handle, device body, oval nail bit, oval nail bin and nail bit bar; The front end of device body is connected with oval nail bit, and the rear end of device body is connected with flexible handle, and described oval nail bin is provided with oval nail kit, oval nail seat, first group of anastomosis staple and second group of anastomosis staple; The top of described oval nail bit is flexibly connected with nail bit bar, the top major axis of described oval nail bit and the angle of nail bit bar are greater than 90 °, the top minor axis of described oval nail bit and the angle of nail bit bar equal 90 °, the length of described first group of anastomosis staple is 35%～95% of second group of anastomosis staple length, oval nail seat is associated with oval nail kit operability, and oval nail seat is coincide and is connected with oval nail kit activity.
The length of described first group of anastomosis staple can be 35%～95% of second group of anastomosis staple length, and the length of described first group of anastomosis staple is preferably 65%～85% of second group of anastomosis staple length.
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 circular stapler, the present invention 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. 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 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 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 can solve coincide rear Anastomotic bleeding, anastomotic leakage and residual three problems of anastomotic stoma anastomosis staple.

The specific embodiment
Referring to Fig. 1～5, the embodiment of the present invention is provided with flexible handle 1, device body 2, oval nail bit 3, oval nail bin 4 and nail bit bar 5; 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 5, the top major axis 31 of described oval nail bit 3 is greater than 90 ° with the angle of nail bit bar 5, the top minor axis 32 of described oval nail bit 3 equals 90 ° with the angle of nail bit bar 5, and the length of described first group of anastomosis staple 43 is 70% of second group of anastomosis staple 44 length; 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 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.In Fig. 2, labelling 6 is intestinal wall.
The present invention has structurally done important improvement, not only overcome existing 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 the present invention, improving alimentary tract anastomosis, avoids the aspects such as intestinal tract complication to have outstanding technique effect.
