Abstract

The utility model discloses a nail barn assembly, which comprises a nail barn, a nail barn hole arranged through the surface of the nail barn and a nail push jack arranged inside the nail barn hole capable of relatively sliding with respect to the nail barn hole.The cross sections of both the nail barn hole and the nail push jack are equipped with a pair of long edges.The distance between the long edges of the nail barn hole is greater than the distance between the long edges of the nail push jack.Since the nail barn hole is in point contact with the nail push jack, the friction therebetween is small.Therefore, the percussion force of the whole assembly is relatively smaller.

Description

Nail bin groupware

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, comprise nail bin, the nail bin hole on nail bin surface is located in perforation, the pushing slice of nail that places in the described nail bin hole and can slide relatively with it, the cross section of described nail bin hole and pushing slice of nail has included a pair of long limit, and the distance between the long limit in described nail bin hole is greater than the distance between the long limit of described pushing slice of nail.

Further, the cross section of described nail bin hole and pushing slice of nail is hexagon, and described long limit is the one opposite side.

Further, be equipped with a recess on the long limit in described nail bin hole, the beeline between the described recess equals the distance between the long limit of described pushing slice of nail.

Further, be equipped with a projection on the long limit of described pushing slice of nail, the longest distance between the described projection equals the distance between the long limit in described nail bin hole.

Further, the linkage section between the long limit in described nail bin hole comprises a fillet, and the linkage section between the long limit of described pushing slice of nail comprises 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.

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 has included a pair of long limit 7,8.In conjunction with first embodiment shown in Figure 3, the distance L between the long limit 7 in described nail bin hole 2 is greater than the distance D between the long limit 8 of described pushing slice of nail 3.And the linkage section between the long limit 7 in described nail bin hole 2 comprises a fillet 5, and the linkage section between the long limit 8 of described pushing slice of nail 3 comprises a fillet 6, and the fillet 5 in the fillet 6 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 that the point at two ends contacts, and frictional force diminishes greatly.

Further, the cross section of described nail bin hole and pushing slice of nail all can be arranged to hexagon same as the prior art, and described

long limit

7,8 can be the one opposite side.Certainly, other shape also is not precluded within outside this utility model.

Because 2 contacts are not too firm, shown among second embodiment shown in Figure 4, be equipped with a recess 9 on the long limit 7 in described nail bin hole 2, the beeline D between the described recess 9 equals the distance D between the long limit 8 of described pushing slice of nail 3.Shown among the 3rd embodiment shown in Figure 5, be equipped with a projection 10 on the long limit 8 of described pushing slice of nail 3, the longest distance between described protruding 10 equals the distance between the long limit 8 in described nail bin hole 2.

The multiple spot contact that forms like this under the prerequisite that can guarantee to reduce friction, can reach the effect of firm pushing slice of nail again.

This utility model still has numerous embodiments, for example wave cake contact, broken line form point contact etc., all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of the present utility model.
