Abstract
The utility model discloses a nail bin assembly, comprising a nail bin, a nail bin hole in a through arrangement at the surface of the nail bin, a nail pushing sheet disposed in the nail bin hole and capable of sliding relative to the nail bin hole, the cross section of the nail bin hole comprises a straight line, correspondingly, the cross section of the nail pushing sheet comprises a circular arc line; or, the cross section of the nail bin hole comprises a circular arc line, correspondingly, the cross section of the nail pushing sheet comprises a straight line; and the circular arc line is tangential to the straight line. Compared with the prior art, the beneficial effects of the nail bin assembly are mainly in that: Since a point contact is provided between the nail bin assembly and the nail pushing sheet, friction is smaller between the nail bin assembly and the nail pushing sheet, and percussion of the whole apparatus is relatively smaller.
Description
Technical field
This utility model relates to a kind of nail bin groupware of surgical operation bookbinding device, belongs to technical field of medical instruments.
Background technology
The surgical operation bookbinding device is to be used for the important tool that surgical operation carries out wound suture, existing at present trend of eliminating manual suture.Wherein, linear type/arc line type bookbinding device can carry out the closure of wound tissue, and the linear type cutting bookbinding device can be organized cutting when carrying out wound tissue's closure, and the tubular type cutting bookbinding device can carry out the stitching and the cutting of tubular type tissue.
The linear type cutting bookbinding device that discloses with U.S. Pat 7055730 is an example, and this bookbinding device can respectively be driven into two row's anastomosis staples simultaneously in the both sides of tissue, cuts from breaking between the tissue of having sewed up in both sides with push broach then.At present this stiching instrument of wide clinical application is carried out stomach, jejunum side to side anastomosis, and the making of stomach tube, pulmonary divide operations such as excision.Its advantage is that stitch length is long, can organize cutting in suture tissue.Wherein apparatus comprises two clamps and a closed handle up and down, up and down two clamps one of them be provided with nail bin, another is provided with nail anvil relatively, tissue is placed between nail bin and the nail anvil, then closed handle is closed, organize just to be clamped between the upper and lower closed clamp, promote ejector pin bar and push broach bar then, the stitching that just can finish tissue with separate.
In the present surgical operation bookbinding device use, ubiquity percussion power bigger problem, particularly linear type cutting bookbinding device, the direction that goes out nail and the power of percussion to apply direction different, the problem that percussion power is bigger is more outstanding.Cause the big factor of percussion power a lot, mechanism's complexity can cause percussion power big, and the frictional force between each mating parts greatly also can cause percussion power big.Because percussion power is big, feeling of fatigue in use appears in doctor easily.
As depicted in figs. 1 and 2, the nail bin groupware 100 of this apparatus comprises nail bin 1, is located at the nail bin hole 2 on nail bin 1 surface, places suturing nail and pushing slice of nail 3 in the nail bin hole 2.Because nail bin hole 2 is a profile phase hexagon together with pushing slice of nail 3, so frictional force between the two is very big, causes the percussion power of apparatus also very big.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is to propose the less nail bin groupware of a kind of power of percussion.
The purpose of this utility model will be achieved by the following technical programs:
A kind of nail bin groupware comprises nail bin, connects the nail bin hole of being located at the nail bin surface, the pushing slice of nail that places in the described nail bin hole and can slide relatively with it, and the cross section in described nail bin hole comprises a straight line, accordingly, the cross section of described pushing slice of nail comprises a circular arc limit; Perhaps, the cross section in described nail bin hole comprises a circular arc limit, and accordingly, the cross section of described pushing slice of nail comprises a straight line; Described circular arc limit and straight line are tangent.
Further, the straight line in described nail bin hole or the linkage section between the circular arc limit comprise a fillet, and the circular arc limit of described pushing slice of nail or the linkage section between the straight line comprise a fillet, and the fillet in the fillet of described pushing slice of nail and described nail bin hole is inscribe mutually.
Further, described nail bin groupware is applicable to linear type/arc line type bookbinding device, linear type cutting bookbinding device, tubular type cutting bookbinding device.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in: owing to be the some contact between nail bin hole and the pushing slice of nail, so frictional force between the two is less, so the percussion power of whole apparatus is also less relatively.

The specific embodiment
This utility model has disclosed a kind of nail bin groupware 100, is applicable to linear type/arc line type bookbinding device, linear type cutting bookbinding device, tubular type cutting bookbinding device etc.
As shown in Figure 1, consistent with prior art, nail bin groupware 100 comprises nail bin 1, is located at the nail bin hole 2 on nail bin 1 surface, places in the nail bin hole 2 and the suturing nail and the pushing slice of nail 3 that can slide relatively with it.In the apparatus that has, described pushing slice of nail 3 can also be fixed on the same ejector pin bar 4.
In this utility model, the cross section of described nail bin hole 2 and pushing slice of nail 3 is a pair of tangent straight line 7 and circular arc limit 8.In conjunction with first embodiment shown in Figure 3, the cross section in described nail bin hole 2 comprises a circular arc limit 8, and accordingly, the cross section of described pushing slice of nail 3 comprises a straight line 7, and described circular arc limit 8 and straight line 7 are tangent.
In conjunction with second embodiment shown in Figure 4, the cross section in described nail bin hole 2 comprises a straight line 7, and accordingly, the cross section of described pushing slice of nail 3 comprises a circular arc limit 8, and described circular arc limit 8 and straight line 7 are tangent.
Further, the straight line or the linkage section between the circular arc limit in described nail bin hole comprise a fillet 5, and the circular arc limit or the linkage section between the straight line of described pushing slice of nail comprise a fillet 6, and the fillet 6 in the fillet 5 of described pushing slice of nail and described nail bin hole is inscribe mutually.Like this, described nail bin hole 2 and pushing slice of nail 3 only are to contact, and frictional force diminishes greatly.Certainly; tangent implementation has a variety of; for example round tangent; wave is tangent, and ellipse is tangent or the like, can not be exhaustive at this; adopt tangent principle to realize that the single-point or the multiple spot of nail bin hole 2 and pushing slice of nail 3 contact; the scheme that all belongs to equivalents of the present utility model, all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of the present utility model.
