Background technology
Medical linear seaming and cutting device is widely used in wound suture, interior tissue is sewed up and cutting.Typical medical linear seaming and cutting device such as US Patent No. 5129570 announcements, have simultaneously and sew up and cut two functions, namely when carrying out wound suture, excess tissue is excised.Such medical linear seaming and cutting device generally comprises upper and lower two clamps, is oppositely arranged on 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; Being provided with in this nail bin can be along apparatus axis mobile ejector pin bar and the far-end push broach bar that is provided with cutting knife simultaneously, and an end of described ejector pin bar and push broach bar all is equipped on the slide block; Described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and suturing nail in each nail hole; Described slide block moves and drives described ejector pin bar and promote pushing slice of nail successively and push described suturing nail to nail anvil to form in and treat on the suture tissue, and drives described cutting knife the tissue between described nail bin and nail anvil is cut off or otch.
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 by 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 in the fracture easily of stressed back, and pin can not well play the effect that is connected and fixed, thereby the nail anvil shell comes off, and causes the seaming and cutting device to use.
Summary of the invention
Purpose of the present invention 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.
Purpose of the present invention will be achieved by the following technical programs:
The medical linear groove part is cut device, comprising: can be mutually the closed or upper and lower clamp opened, be oppositely arranged on 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 described near-end of going up clamp is the nail anvil shell, and described nail bin is arranged on down in the nail bin frame of clamp far-end, and described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and the suturing nail of mutual butt in each nail hole; Described nail anvil sidewall offers a pin-and-hole, and the middle part of described pin convexes with a circle boss to the pin outer surface, and the diameter of described boss is greater than described pin-and-hole diameter.
Preferably, an end of described boss is set to slope.
Preferably, symmetry offers two breach on the described pin-and-hole.
Preferably, fixing that described nail anvil and nail anvil enclosure axis make progress fixed by draw-in groove, and described nail anvil shell is provided with for the grab of realizing that nail anvil shell and nail anvil are vertically fixed.
Preferably, described nail anvil inner surface of outer cover inwardly convexes with a projection, offers a groove on the described nail anvil, described projection and described groove clamping.
Preferably, described 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 described nail anvil shell external diameter that relative described grab forms the arc footpath.
Beneficial effect of the present invention 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
The present invention 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 mutually the closed or upper and lower clamp opened, be oppositely arranged on 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 described near-end of going up clamp is the nail anvil shell, and described nail bin is arranged on down in the nail bin frame of clamp far-end, and described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and the suturing nail of mutual butt in each nail hole;
As Fig. 1, shown in Figure 3, the far-end of the near-end of described nail anvil 1 and nail anvil shell 2 is fixing by pin 13, fixing on axially of described nail anvil 1 and nail anvil shell 2 fixed by draw-in groove, concrete, described nail anvil shell 2 inner surfacies inwardly convex with a projection 21, offer a groove 12 on the described nail anvil 1, described projection 21 and described groove 12 clampings.
Described nail anvil shell 2 is provided with for the grab 22 of realizing that nail anvil shell 2 and nail anvil 1 are vertically fixed.Concrete, described 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 described nail anvil shell 2 external diameters that relative described grab 22 forms the arc footpath.
Described nail anvil 1 sidewall offers a pin-and-hole 11, and the middle part of described pin 13 convexes with a circle boss 14 to pin 13 outer surfaces, and the diameter of described boss 14 is greater than described pin-and-hole 11 diameters.
In order to make pin 13 can better enter pin-and-hole 11, an end of described boss 14 is set to slope 15.
In order to make pin-and-hole 11 that better dilatancy be arranged, be conducive to entering of pin 13, symmetry offers two breach 16 on the described pin-and-hole 11.
Below in conjunction with operating process under the Brief Description Of Drawings.
The end that pin 13 is had an oblique profile 15 is aimed at the pin-and-hole 11 on the nail anvil, will sell 13 then and knock in.Owing to have boss 14 on the pin 13, and the diameter of boss 14 is greater than the diameter of pin-and-hole 11, so, after pin 13 enters pin-and-hole 11, can not make pin 13 loosening not coming off owing to transportation.
The projection 21 of nail anvil shell 2 and the groove on the nail anvil 1 12 are aimed at, and firmly press then, make projection 21 enter groove 12, simultaneously, guarantee that 4 grabs 22 catch on the nail anvil 2.Like this, nail anvil shell 2 and nail anvil 1 are vertically and all obtained fixing axially.Of the present invention simple in structure easy to process, practical.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
