    • A staple and stapler for injecting the staple in a manner so that the staple maintains a near constant width upon penetration of material to be joined and during staple closure/forming such that material perturbation and staple to staple spacing may be minimized. The staple has a rectilinear bridge part from which depend oppositely positioned side parts and from the side parts a pair of straight legs. In a preferred embodiment, the oppositely positioned side parts consist of a proximal arcuate section attached to the bridge part and an oppositely directed distal arcuate section attached to the legs. The legs may have sharpened points. Also disclosed is a stapler adapted to force the oppositely directed distal arcuate sections outward, in one embodiment, thereby forcing a reaction of the legs of the staple to face each other in linear alignment and form a closed staple. The unpreloaded fully-formed staple may be deformed in situ by means of a preload part on a cam slide so as to create a U-shaped central portion for the compression of captured material. Alternatively, a preformed staple with the U-shaped central portion may also be used.
    • 一种钉和订书机,用于以这样的方式注射订书钉,使得订书钉在待接合的材料穿透时以及在缝合期间/成型期间保持接近恒定的宽度,使得材料扰动和订书针至订书钉的间隔可以最小化。 订书钉具有直线桥部分,从该位置的相对定位的侧部和从侧面部分是一对直的腿。 在优选实施例中,相对定位的侧面部分由附接到桥接部分的近端弧形部分和附接到腿部的相反方向的远端弧形部分组成。 腿可能有磨尖点。 还公开了一种订书机,其在一个实施例中适合于将相对方向的远端弓形部分向外强制,由此迫使订书针的腿部以线性对准的方式彼此面对并形成封闭的订书钉。 未加载的完全成型的订书钉可以通过凸轮滑块上的预加载部分原位变形,以便形成用于压缩所捕获材料的U形中心部分。 或者,还可以使用具有U形中心部分的预制钉。
