Description
Technical field
The present invention relates to technical field of medical instruments, the round or anorectal anastomat of especially a kind of disposable use with circular nail supporting base.
Background technology
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 manual suture.Disposable use stitching work round or anorectal anastomat relies on suturing nail to complete, and the suturing nail in nail bin is advanced the interior stressed bending of nail groove of nail supporting base, and relative skin histology is sewed up.Having relatively high expectations of suture operation, after suturing nail bending, need to form strict B font, existing disposable use suturing nail round or anorectal 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.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of disposable use with circular nail supporting base round or anorectal anastomat, when packing suturing nail into and using, after its suturing nail bending, can form qualified B font.
The technical solution adopted for the present invention to solve the technical problems is: the round or anorectal anastomat of a kind of disposable use with circular nail supporting base, there is circular nail supporting base, on the end face anchor ring of described circular nail supporting base, offer nail grooved ring more than a circle, described nail grooved ring has more than 1 the nail groove along circumferential arrangement, described nail groove comprises left nail groove, right nail groove and be positioned at left nail groove, arc convex between right nail groove, left nail groove has from left to right a left side the first arc groove that transition successively connects, left the second arc groove, right nail groove has from left to right the right side the second arc groove that transition successively connects, right the first arc groove, arc convex respectively with left the second arc groove, right the second arc groove transition connects, a described left side the first arc groove and the section radius of right the first arc groove are 2.1 ± 0.05mm, a described left side the second arc groove and the section radius of right the second arc groove are 0.97 ± 0.05mm, the section radius of described arc convex is 0.18 ± 0.02mm.
Further, a described left side the first arc groove and the section radius of right the first arc groove are 2.1mm, and a described left side the second arc groove and the section radius of right the second arc groove are 0.97mm, and the section radius of described arc convex is 0.18mm.
Further, a described left side the first arc groove and the top end opening of right the first arc groove are greater than the bottom opening of self, and a described left side the second arc groove and the top end opening of right the second arc groove are greater than the bottom opening of self.
Further, on the end face anchor ring of described circular nail supporting base, offer 2 circle nail grooved rings.
The invention has the beneficial effects as follows: the round or anorectal anastomat of a kind of disposable use with circular nail supporting base of the present invention, by the concrete structure of 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, while packing suturing nail use into, 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.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of circular nail supporting base in invention;
Fig. 2 is the schematic partial cross-sectional view at single nail groove place in circular nail supporting base of the present invention; 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.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Fig. 1 Fig. 2, round or the anorectal anastomat of a kind of disposable use with circular nail supporting base, there is circular nail supporting base, on the end face anchor ring of circular nail supporting base, offer 2 circle nail grooved rings, nail grooved ring has a plurality of nail grooves 1 along circumferential arrangement, nail groove 1 comprises left nail groove, right nail groove and be positioned at left nail groove, arc convex 13 between right nail groove, left nail groove has from left to right a left side the first arc groove 11 that transition successively connects, left the second arc groove 12, right nail groove has from left to right the right side the second arc groove 14 that transition successively connects, right the first arc groove 15, arc convex 13 respectively with left the second arc groove 12, right the second arc groove 14 transition connect.
