    • Opposable surgical clamp members having opposable resilient pads with wedge-shaped and cylindrical protrusions extending from the surfaces of the pads and the use of such members for occluding vessels and other tubular body structures are described. The protrusions are arranged such that when the members are moved toward one another, the protrusions of one pad interdigitate with the protrusions of the other pad. Upon engagement with a vessel, portions of the vessel are forced into the interdigital spaces providing for improved gripping of the vessel. The protrusions also resist lateral or transverse movement of a clamped vessel relative to the pads. The existence of holes under the pad surface alters the relative resiliency of the pad, allowing for an overall pad resiliency that minimizes trauma to a clamped vessel while allowing the local resiliency of the protrusions themselves to be of a hardness to avoid excessive deflection and retain the desired shape and gripping ability.
    • 描述了具有可从垫的表面延伸的楔形和圆柱形突起的相对的弹性垫以及用于封闭容器和其它管状结构的这种构件的使用的相对的手术夹具。 突起被布置成使得当构件彼此移动时,一个垫的突起与另一个垫的突起相互交错。 在与容器接合时,容器的部分被迫进入叉指间空间,从而改善对容器的抓握。 这些突起还抵抗夹持的容器相对于衬垫的横向或横向移动。 衬垫表面下方的孔的存在改变了垫的相对弹性,允许整体衬垫弹性使得对夹紧的容器的创伤最小化,同时允许突起本身的局部弹性具有硬度以避免过度偏转并保持 期望的形状和抓握能力。
