Last clamp is made up of the nail anvil of far-end and the nail anvil shell of near-end, nail anvil and nail anvil shell being connected through pin.Concrete, the brace on the nail anvil shell offers pin-and-hole, and the pin-and-hole that pin passes brace connects.But interference fit is adopted in such connection, makes brace rupture easily in stressed back, and pin can not well play and connect fixed effect, thereby the nail anvil shell comes off, and causes the seaming and cutting device to use.
The utility model content
The purpose of this utility model solves the problems of the technologies described above, and proposes a kind ofly to have anti-shotpin and come off and prevent that the medical linear groove part that nail anvil shell and nail anvil come off from cutting device.
The purpose of this utility model will be achieved through following technical scheme:
The medical linear groove part is cut device, comprising: can be each other the closed or upper and lower clamp opened, be oppositely arranged on the nail anvil and the nail bin of upper and lower clamp far-end and the closed handle that is used for closed upper and lower clamp; The said near-end of going up clamp is the nail anvil shell, and said nail bin is arranged on down in the nail bin frame of clamp far-end, and said nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with the pushing slice of nail and the suturing nail of mutual butt in each nail hole; Said nail anvil sidewall offers a pin-and-hole, and the middle part of said pin convexes with a circle boss to the pin outer surface, and the diameter of said boss is greater than said pin-and-hole diameter.
Preferably, an end of said boss is set to slope.
Preferably, symmetry offers two breach on the said pin-and-hole.
Preferably, fixing that said nail anvil and nail anvil enclosure axis make progress fixed through draw-in groove, and said nail anvil shell is provided with and is used to realize nail anvil shell and the vertical fixed grab of nail anvil.
Preferably, said nail anvil inner surface of outer cover inwardly convexes with a projection, offers a groove on the said nail anvil, said projection and said groove clamping.
Preferably, said grab is evenly equipped with two rows in nail anvil inner surface of outer cover symmetry, and every row's grab is provided with more than one at least, and it is suitable with said nail anvil shell external diameter that relative said grab forms the arc footpath.
The beneficial effect of this utility model is mainly reflected in: nail anvil shell and nail anvil adopt draw-in groove to carry out the fixing of lengthwise position, fixing on employing grab and nail anvil carry out axially on the nail anvil shell.Simultaneously, pin is provided with boss, has prevented coming off of pin.Simple in structure, practical.

The specific embodiment
This utility model has disclosed a kind of medical linear groove part and has cut device; Comprise: the medical linear groove part is cut device; Comprise: can be each other the closed or upper and lower clamp opened, be oppositely arranged on the nail anvil and the nail bin of upper and lower clamp far-end and the closed handle that is used for closed upper and lower clamp.
The said near-end of going up clamp is the nail anvil shell, and said nail bin is arranged on down in the nail bin frame of clamp far-end, and said nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with the pushing slice of nail and the suturing nail of mutual butt in each nail hole;
Like Fig. 1, shown in Figure 3; The far-end of the near-end of said nail anvil 1 and nail anvil shell 2 is fixing through pin 13; Fixing on axially of said nail anvil 1 and nail anvil shell 2 fixed through draw-in groove, and concrete, said nail anvil shell 2 inner surfacies inwardly convex with a projection 21; Offer a groove 12 on the said nail anvil 1, said projection 21 and said groove 12 clampings.
Said nail anvil shell 2 is provided with and is used to realize nail anvil shell 2 and nail anvil 1 vertical fixed grab 22.Concrete, said grab 22 is evenly equipped with two rows in nail anvil shell 2 inner surface symmetries, and every row's grab is provided with more than one at least, and preferred every row is provided with 2.It is suitable with said nail anvil shell 2 external diameters that relative said grab 22 forms the arc footpath.
Said nail anvil 1 sidewall offers a pin-and-hole 11, and the middle part of said pin 13 convexes with a circle boss 14 to pin 13 outer surfaces, and the diameter of said boss 14 is greater than said pin-and-hole 11 diameters.
In order to make pin 13 can better get into pin-and-hole 11, an end of said boss 14 is set to slope 15.
