Abstract

The utility model relates to a disposable linear anastomat, which is provided with a linear nail seat, wherein more than one row of nail groove line is arranged on the linear nail seat, and a plurality of nail grooves are uniformly arranged on the nail groove lines at intervals. The nail groove comprises a first left arc-shaped groove, a second left arc-shaped groove, an arc-shaped bulge, a second right arc-shaped groove and a first right arc-shaped groove which are orderly connected from left to right in a transition mode, wherein the radiuses of the sections of the first left arc-shaped groove and the first right arc-shaped groove are 1.45+_0.05mm, the radiuses of the sections of the second left arc-shaped groove and the second right arc-shaped groove are 0.9+_0.05mm, and the radius of the section of the arc-shaped bulge is 0.1+_0.02mm. A suturing nail is pushed into the nail groove of the liner nail seat and is forced to bend when the disposable linear anastomat is used by being provided with the suturing nail, thereby being capable of forming a qualified B shape, and effectively guaranteeing suturing quality of the suturing nail.

Description

Disposable use linear anastomat
Technical field
This utility model relates to technical field of medical instruments, especially a kind of disposable use linear anastomat.
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 the manual suture.The stitching work of disposable use linear 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 is sewed 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 linear 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 linear 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 linear anastomat, has the linear type nail supporting base, described linear type nail supporting base is provided with the above nail groove row of a row, described nail groove row has evenly spaced nail groove more than 1, described nail groove comprises from left to right a left side the first arc groove that successively transition connects, left the second arc groove, arc convex, right the second arc groove, right the first arc groove, the section radius of described left the first arc groove and right the first arc groove is 1.45 ± 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 0.1 ± 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 1.45mm, 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 0.1mm.
Further, described linear type nail supporting base is provided with two nail-arranging slots row.
The beneficial effects of the utility model are: a kind of disposable use linear 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 this utility model cathetus type nail supporting base;
Fig. 2 is the schematic partial cross-sectional view at single nail groove place in the linear type 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.
The specific embodiment
By reference to the accompanying drawings this utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with this utility model.
Shown in Figure 2 such as Fig. 1, a kind of disposable use linear anastomat has the linear type nail supporting base, and the linear type nail supporting base is provided with the above nail groove row of a row, and following closely as shown in Figure 1 groove row amount is 2 rows, and nail groove row has evenly spaced a plurality of nail groove 1.
Nail groove 1 comprises from left to right a left side the first arc groove 11, left the second arc groove 12, arc convex 13, right the second arc groove 14, right the first arc groove 15 that successively transition connects, left the first arc groove 11 is 1.45 ± 0.05mm, preferred 1.45mm with the section radius of right the first arc groove 15.Left the second arc groove 12 is 0.9 ± 0.05mm, preferred 0.9mm with the section radius of right the second arc groove 14.The section radius of arc convex 13 is 0.1 ± 0.02mm, preferred 0.1mm.
Left the second arc groove 12 is symmetrical arranged with the centrage of right the second arc groove 14 with respect to arc convex 13, and left the first arc groove 11 is symmetrical arranged with the centrage of right the first arc groove 15 with respect to arc convex 13.
A kind of disposable use linear anastomat of the present utility model, concrete structure by strict design nail groove 1, the section radius of left the first arc groove 11 of strict design, left the second arc groove 12, arc convex 13, right the second arc groove 14, right the first arc groove 15, when the suturing nail of packing into uses, the nail groove 1 interior stressed bending that suturing nail is advanced nail supporting base can form qualified B font, effectively guarantees the suture quality of suturing nail.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the description, must determine its technical scope according to the claim scope.
