Abstract
The utility model relates to a single-use arc-shaped cutting anastomat which comprises an arc-shaped nail abutting seat. An arc-shaped cutter groove is formed in the middle portion of the arc-shaped nail abutting seat. Arc-shaped nail groove rows are arranged on the front side and the back side of the arc-shaped cutter groove. The arc-shaped nail groove rows are provided with nail grooves. Each nail groove comprises a left nail groove, a right nail groove and an arc-shaped boss arranged between the left nail groove and the right nail groove. Each left nail groove is provided with a left first arc-shaped groove and a left second arc-shaped groove. Each right nail groove is provided with a right first arc-shaped groove and a right second arc-shaped groove. The radius of the cross section of each left first arc-shaped groove and the radius of the cross section of each right first arc-shaped groove are 1.35+/_ 0.05mm. The radius of the cross section of each left second arc-shaped groove and the radius of the cross section of each right second arc-shaped groove are 0.9+/_0.05mm. The radius of the cross section of each arc-shaped boss is 0.16+/_0.02mm. When the single-use arc-shaped cutting anastomat is filled with suturing nails to be used, the suturing nails are pushed into the nail grooves of the nail abutting seat and are bent to be in a regular B shape after being stressed, and therefore suturing quality of the suturing nails is guaranteed.

Along with the improving constantly of China's scientific and technological level, the design and fabrication technology of anastomat product has had significant progress in recent years.Anastomat obtains using more and more widely at the various operating end ends such as esophagus, Stomach duodenum, colon, rectum, biliary tract, hemorrhoid, distolateral, side to side anastomosis, progressively substitutes the manual suture.The stitching work of disposable use arc-shaped cutting anastomat relies on suturing nail to finish, and the suturing nail in the nail bin is advanced the interior stressed bending of nail groove of nail supporting base, so that relative skin histology obtains sewing up.Having relatively high expectations of suture operation, need to form strict B font after the suturing nail bending, the suturing nail of existing disposable use arc-shaped cutting anastomat is difficult to the B font that reaches strict, and the part needle point of suturing nail exposes, can cause foreign body sensation to patient body, patients ' recovery is impacted.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of disposable use arc-shaped cutting anastomat is provided, can form qualified B font after its suturing nail bending when the suturing nail of packing into uses.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of disposable use arc-shaped cutting anastomat, has the arc nail supporting base, the middle part of described arc nail supporting base is provided with the curved knife groove, before the described curved knife groove, rear both sides are provided with at least string cuved nail groove row, described cuved nail groove row has evenly spaced nail groove more than 1, described nail groove comprises left nail groove, right nail groove and be positioned at left nail groove, arc convex between the right nail groove, left nail groove has from left to right a left side the first arc groove that successively transition connects, left the second arc groove, right nail groove has from left to right the right side the second arc groove that successively transition connects, right the first arc groove, arc convex respectively with left the second arc groove, right the second arc groove transition connects, the section radius of described left the first arc groove and right the first arc groove is 1.35 ± 0.05mm, the section radius of described left the second arc groove and right the second arc groove is 0.9 ± 0.05mm, the section radius of described arc convex is 0.16 ± 0.02mm, described left the second arc groove and right the second arc groove are symmetrical arranged with respect to the centrage of arc convex, and described left the first arc groove and right the first arc groove are symmetrical arranged with respect to the centrage of arc convex.
Further, the section radius of described left the first arc groove and right the first arc groove is 1.35mm, and the section radius of described left the second arc groove and right the second arc groove is 0.9mm, and the section radius of described arc convex is 0.16mm.
Further, the top end opening of described left the first arc groove and right the first arc groove is greater than the bottom opening of self, and the top end opening of described left the second arc groove and right the second arc groove is greater than the bottom opening of self.
Further, the forward and backward both sides of described curved knife groove are provided with all 2 row cuved nail grooves row.
The beneficial effects of the utility model are: disposable use arc-shaped cutting anastomat of the present utility model, concrete structure by strict design nail groove, the section radius of left the first arc groove of strict design, left the second arc groove, arc convex, right the second arc groove, right the first arc groove, when the suturing nail of packing into uses, the interior stressed bending of nail groove that suturing nail is advanced nail supporting base can form qualified B font, effectively guarantees the suture quality of suturing nail.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is the structural representation of arc nail supporting base in this utility model;
Fig. 2 is the schematic partial cross-sectional view at single nail groove place in the arc nail supporting base of the present utility model;
Wherein: 1. follow closely groove, 11. left the first arc grooves, 12. left the second arc grooves, 13. arc convex, 14. right the second arc grooves, 15. right the first arc grooves.
