Description
Technical field
This utility model relates to disposable stapling technique in anus reservation field, and especially a kind of single use internal orifice is cut and closed anastomat.
Background technology
On market, existing various types of anastomat, is widely used in each several part tissue of coincided with human body, can reduces operating time in surgical operation, and improve surgical quality, anastomotic stoma is solid and reliable, and haemostatic effect is good.
But existing circular Endo-GIA is in use, still there are problems:
The first, in existing structure, nail bin shape is cylindrical, and there is obstruction in its visual field, can not form open surgical field of view, and wound surface Oversewing space face is less, inconvenient medical personnel's operation.
The second, the nail groove on existing nail bin is normally symmetrical arranged, be 2 queuings close wound surface+0 queue up cut and organize wound surface pattern.In actual use, wound surface size differs, the stitching wound surface of usual anastomat head is 1 centimeter ~ 1.5 centimeters, suppose under the stitching wound surface of 1 centimeter, 2 conventional nail-arranging slots generally only have 5 pieces of suturing nails, sewing density is less, and such stitching wound surface still easily occurs hemorrhage, can not bear 220 mmhg pressure problems.
3rd, when conventional round anastomat is sewed up, be all nail supporting base motion, nail bin does not move, and will change classic screw direction of rotation like this, does not change the operating habit of doctor, is more inconvenient concerning the operation process of anxiety.
4th, existing nail bin and nail supporting base and non-dismountablely between nail supporting base with the body of a gun to be connected, user of service can not realizing self disassembling, and especially nail bin can not independently be changed, and can only change by whole anastomat when change, equipment consumption is larger.
Summary of the invention
