    摘要： A system for facilitating folding a soft intraocular lens. A supporting and positioning structure associated with a base or frame presents the lens so that forceps tips are automatically positioned near opposite sides of the lens and maintained in that position. A forming means automatically moves the forceps tips with respect to the lens to fold the optic portion of the lens within the tips. The lens is accurately and reliably folded in the forceps tips to securely grip the lens in a desired position with reduced risk of damage to the optic portion of the lens.

    摘要： A clamping device which includes a pair of elongated members which are pivotably but releasably connected. A pivot mechanism exists between gripping ends and handle ends of the elongated members. Female and male members comprise a box hinge whereby the cam holds the elongated members in a secure but pivotable relationship between a closed position for the gripping ends and a maximum open position. If the elongated members are moved beyond the maximum open position, the male cam member can be separated from the female receptor member.

    摘要： A surgical snare having a wire which forms the snare loop made from a shape memory effect metallic alloy which exhibits superelasticity at room temperature. The wire is trained so that it assumes an intermediate snare loop size in an unrestrained free state. From this trained free state configuration, the loop can be expanded to a large loop and contracted to a very small loop without permanent deformation from the trained intermediate state. This range of movement enables an expanded range of applicability for snares in general, and also enables reducing the instrument tip size with improved loop configuration.

    摘要： An interference screw is provided by machining a fragment of autograft or allograft cortical bone from a donor or from a recipient's amputated bone. The interference screw has a cortical surface into which a self-tapping thread is machined. The interference screw has a machined pointed, rounded or flush end and an opposite machined end which mates with a drive means, and has advantages over conventional interference screws known in the art in that subsequent to implantation, no residual hardware that must later be removed remains at the implant site.

    摘要： An apparatus and method for implantation of intraocular lenses includes a resilient tubular sling which is positionable over parallel working ends of a crossover forceps. The sling allows an intraocular lens to be folded or curled up therein and held in that folded up position with the forceps tips in a closed position. The forceps presents a narror-in-cross-section moving crossover point behind the tips to allow the forceps tips to be inserted through a small incision in the eye, and then open to release the lens once within the eye. By maintaining the crossover point at the small incision, the forceps can release the lens even though it requires the opening of the forceps tips to a position wider than the incision in the eye. The resilient sling holds the folded lens compactly during movement through the small incision, and assists in urging a controlled release of the lens into the eye. The sling also avoids having to handle the lens with the forceps tips prevents damage to the lens.

    摘要翻译： 用于植入人工晶状体的装置和方法包括弹性管状吊索，其可位于交叉镊子的平行工作端上。 吊索允许眼内透镜在其中折叠或卷曲并保持在折叠位置，镊子尖端处于关闭位置。 镊子在尖端后面呈现横截面移动的交叉点，以允许镊子尖端通过眼睛中的小切口插入，然后打开以在眼睛内释放镜片一次。 通过在小切口处保持交叉点，即使需要将镊子尖端打开到比眼睛中的切口更宽的位置，镊子也可以释放镜片。 弹性吊带在通过小切口移动期间紧凑地保持折叠的透镜，并且有助于将镜片控制释放到眼睛中。 吊带也避免了用镊子尖端处理镜片，防止损坏镜片。

    摘要： A means and method for forming tweezers and tweezers handles out of a single piece of material. The tweezers consist of unitary body including two parallel spaced apart arms which extend from an integrally formed heel end portion The ends of the arms opposite the heel end portion comprise tweezer tips or can be connected to replaceable tweezer tips. In a preferred embodiment, the single piece tweezers are produced by electrical discharge machine process which produces very accurate and precise cuts.
