    • A surgical apparatus for attaching two portions of cutaneous body tissue includes a pair of opposed elongated members having jaws which have tissue gripping members thereon at one end and which are movable toward each other to a closed position to engage two body tissue portions positioned within the members to move the body tissue portions into close approximation. Manually gripping systems of several alternative configurations are provided to actuate a mechanical transmission system to close the jaws. In a preferred embodiment, a fork is movable from a first position to a second position by manually operable devices to move the jaws toward each other. A pair of cam faces is located adjacent the opposite ends of the jaws. As the fork moves to its second position, the tines of the fork engage against the cam faces to move the opposed jaws to their closed position. A plurality of rod-like fasteners are carded in a stacked configuration proximally of the jaws such that when the jaws are in their closed position and the two body tissue portions are held in close approximation. Each rod-like fastener is movable to a position in ingress to penetrate the body tissue portions to attach the body tissue portions together. In another preferred embodiment, the elongated members are biased outwardly by a coil spring and a unique plate-like fastener drive member is provided to facilitate driving a fastener after the jaws are closed. A fastener cartridge is provided with fasteners stacked in a sloped fashion and having a coil spring to bias the fasteners toward the ejection position. Another embodiment includes a rack and gear teeth arrangement for approximating the jaws and for firing the fasteners. The rack and gear teeth function somewhat like a linear analog of a set of rotary gears. A method of attaching cutaneous body tissue portions is also disclosed.
    • 用于附接皮肤体组织的两部分的手术装置包括一对相对的细长构件,其具有在其一端具有组织夹持构件的钳口,并且可相对于彼此移动到关闭位置以接合位于构件内的两个身体组织部分 将身体组织部分移动到近似。 提供了几种替代配置的手动夹紧系统来致动机械传动系统以闭合钳口。 在优选实施例中,叉可以通过手动操作的装置从第一位置移动到第二位置,以将夹爪朝向彼此移动。 一对凸轮面邻近钳口的相对端定位。 当叉移动到其第二位置时,叉的齿与凸轮面接合,以将相对的夹爪移动到其关闭位置。 多个杆状紧固件被卡在卡爪的近侧的堆叠构造中,使得当夹爪处于其关闭位置并且两个身体组织部分保持紧密接近时。 每个杆状紧固件可移动到入口位置以穿透身体组织部分以将身体组织部分附接在一起。 在另一优选实施例中,细长构件被螺旋弹簧向外偏压,并且提供了独特的板状紧固件驱动构件,以便于在夹爪关闭之后驱动紧固件。 紧固件卡盒设置有​​以倾斜方式堆叠的紧固件,并且具有螺旋弹簧以将紧固件偏压到喷射位置。 另一个实施例包括用于近似钳口和用于击发紧固件的齿条和齿轮齿布置。 齿条和齿轮齿有点像一组旋转齿轮的线性模拟。 还公开了附着皮肤组织部分的方法。
