Abstract
The invention provides a nail barrel cover. The nail barrel cover comprises a flat-plate body, wherein a through hole of which the diameter is more than or equal to that of a nail anvil shaft and through which the nail anvil shaft passes is formed in the flat-plate body; an elongated slot is formed along a symmetric line of the flat-plate body; a forked part is arranged at one end of the flat-plate body; the diameter of a circumcircle of the forked part is more than or equal to the maximum diameter of a nail barrel; a bulge is formed on one end face of an arc plate; and the maximum distance between the bulge and the circle center of the through hole is more than the internal diameter of a knife anvil and less than or equal to the internal diameter of a nail anvil. Whether the knife anvil is missed or not can be automatically detected in the mounting process of an instrument; and once the knife anvil is missed, the nail barrel cover can enter the nail anvil when mounted, the distance between a nail anvil component and a nail bin component is changed, and an assembler is reminded of the condition that the knife anvil is missed.

Detailed description of the invention
Present invention is disclosed a kind of nail barrel cover, be applicable to tubular binding strument.
As shown in Figure 2, described tubular binding strument comprises nail-anvil assembly 1 and nail bin groupware 2, and described nail-anvil assembly 1 comprises pin anvil shaft 11, nail anvil 12 and establishes cutter anvil 13 in the inner; Described nail bin groupware 2 comprises nail barrel 21 and the nail bin 22 before being fixed on it, and described nail bin 22 is built-in with the anastomosis staple (not shown) for binding.
As shown in Figure 1, the nail barrel cover 3 of the preferred embodiment of the present invention comprises planar plate-shaped body 30, described planar plate-shaped body 30 offers a diameter and is more than or equal to described pin anvil shaft 11, through hole 31 for making described pin anvil shaft 11 pass through.
Described planar plate-shaped body 30 offers an elongated slot 32 along its line of symmetry, and described elongated slot 32 passes described through hole 31 and extends described planar plate-shaped body, makes the crotched two halves formula of described planar plate-shaped body 30 shape; One end of described elongated slot is the connecting portion 33 connecting this two halves formula planar plate-shaped body.
The other end relative to connecting portion 33 of described planar plate-shaped body 30 is a furcation 34, and the circumscribed circle diameter of described furcation 34 is more than or equal to the maximum gauge of described nail barrel 21, and whole like this furcation 34 just can cover the end face of nail barrel 21 and nail bin 22.Preferably, furcation 34 is arc-shaped, then the diameter of furcation 34 is more than or equal to the maximum gauge of nail barrel 21.
One of them end face 340 of described furcation 34 is convexly equipped with raised line 35, described raised line 35 is outwards divergently be arranged on the end face 340 of this furcation from the center of circle of through hole, the distance D in one end to through hole 31 center of circle away from through hole 31 center of circle of described raised line 35 is greater than the internal diameter of cutter anvil, and is less than the internal diameter of nail anvil.Preferably, the cross section of the cutter anvil of general tubular binding strument is in " several " font, then the internal diameter of described cutter anvil is the minimum diameter of " several " font.
In this preferred embodiment, on one of them end face 340 of described furcation 34, convex is provided with an annulus post 36, the inner hollow diameter of described annulus post 36 equals the diameter of through hole 31, described raised line 35 is divergently arranged at the outside of described annulus post 36, and described raised line 35 is connected to described annulus post 36 near the one end in the through hole center of circle.In general, raised line 35 and annulus post 36, and planar plate-shaped body 30 integrated injection molding.
Preferably, the other end 341 of described furcation is convexly equipped with a cylinder 37, the internal diameter of described cylinder 37 equals the external diameter of described nail barrel 21, so just the end face of whole nail barrel 21 can be packaged in the inside of described cylinder 37.
Shown in composition graphs 2, when nail barrel cover 3 is assembled to tubular binding strument, pin anvil shaft 11 is located in described annulus post 36 and through hole 31.If when being provided with " several " font cutter anvil 13 in nail anvil 12, raised line 35 can be against the surface of described cutter anvil 13, like this because the height of raised line 35 itself causes there is a distance H between nail anvil 12 and nail barrel 21.And now another end face 341 of nail barrel cover 3 closes all nail on nail bin, prevent the anastomosis staple in nail from leaking.
As shown in Figure 3, if when not having " several " font cutter anvil 13 in nail anvil 12, raised line 35 can enter into the inside of nail anvil 12, and the distance between such nail anvil 12 and nail barrel 21 disappears immediately, indirectly in this nail anvil 12 of prompting assembler, cutter anvil 13 is not housed.
In this example, one of them end face of described furcation 34 is convexly equipped with multiple raised line 35, the external diameter of a circle of one end away from the through hole center of circle of all described raised lines 35 is greater than the internal diameter of cutter anvil 13, and the internal diameter being less than or equal to nail anvil 12 can realize technical purpose of the present invention.Certainly, the general protuberance of raised line 35 can also be realized, described protuberance to the ultimate range in the through hole center of circle is greater than the internal diameter of cutter anvil 13, and be less than or equal to the internal diameter of nail anvil 12, the same effect can be played equally, and the concrete shape of everything and protuberance has nothing to do, only relevant with the position of its outermost (distance through hole side farthest), because this side could abut with described cutter anvil 13 effectively.
The second embodiment of the invention that such as Fig. 4 and Fig. 5 discloses and the 3rd embodiment.Concrete the second embodiment as shown in Figure 4, one of them end face 340 of described furcation 34 is convexly equipped with projection 38, and the number of this projection 38 is not limit.In this example, end face 340 is convexly equipped with the projection 38 of a circle, described projection 38 interval and being distributed on the end face of described furcation 34.The ultimate range in described projection 38 to through hole 31 center of circle is greater than the internal diameter of cutter anvil, and is less than or equal to the internal diameter of nail anvil.
The 3rd embodiment as shown in Figure 5, one of them end face 340 of described furcation 34 is convexly equipped with two semicircular ring 39, is separately positioned on the two halves formula body of planar plate-shaped body bifurcated formation.The ultimate range in described semicircular ring 39 to through hole 31 center of circle is greater than the internal diameter of cutter anvil, and is less than or equal to the internal diameter of nail anvil.
Projection 38 and the semicircular ring 39 of the second embodiment and the 3rd embodiment are respectively the protuberance be arranged on the end face of arc plate, and it all can play the effect detecting whether neglected loading cutter anvil voluntarily.
Raised line 35 in above embodiment, projection 38 and semicircular ring 39 at least arrange one just can play the effect detecting whether neglected loading cutter anvil voluntarily, also uniform two or more can be set to, not only can play the effect that detects whether neglected loading cutter anvil but also can come off in nail bin by anti-non-magnetic shim preferably, result of use is better.
Of the present invention simple and reliable for structure, be applicable to promoting.
The present invention still has multiple concrete embodiment, equivalent replaces or equivalent transformation and all technical schemes of being formed, all drops within the scope of protection of present invention.
