摘要： A specimen-receiving receptacle apparatus for use in minimally invasive surgical procedures can be remotely opened and closed from a proximal end of the apparatus, outside of the patient. The apparatus includes a belt having substantial longitudinal rigidity so that the belt can be forced longitudinally into the surgical site to open the specimen-retrieval receptacle from a remote end of the apparatus. The belt can be longitudinally pulled out of the surgical site to close the specimen-retrieval receptacle from outside of the patient. The belt is relatively flexible or easily deformable along an open end of the receptacle without deforming substantially out of the plane of the open receptacle end. This is achieved by aligning the belt with respect to the open end such that a large dimension of the belt is aligned transverse to the plane of the open receptacle end. In a preferred embodiment, the belt is extruded from nylon and has an elliptical cross-sectional shape.

摘要： A surgical retractor having a plurality of widenable and narrowable blades of substantial width, having tissue-contacting surfaces that are not significantly narrower, in a collapsed position, than a guide tube for guiding the retractor blades through a surgical access port to a surgical site during a minimally invasive surgical procedure. Each retractor blade includes a relatively large, preferably planar, tissue-contacting surface for displacing or repositioning internal body tissue, such as an internal organ, for temporary displacement away from the surgical site. After insertion through a surgical access port one or more of the retractor blades can be widened laterally to substantially space distal ends of the retractor blades apart for maximum contact against and over a substantial area of the tissue to be displaced during the surgical procedure. After completion of the operative procedure, the retractor blades can be narrowed by nesting the blades together and the retractor can be easily and safely withdrawn from the access port.
摘要翻译： 一种手术牵开器，其具有多个宽度可变且可变窄的刀片，所述多个宽度可变且可变窄的刀片具有在折叠位置上不显着变窄的组织接触表面，该引导管用于将牵开器刀片通过手术进入端口引导至外科手术部位 微创外科手术。 每个收缩器叶片包括相对大的，优选平面的组织接触表面，用于移位或重新定位诸如内部器官的内部身体组织，用于远离手术部位的临时位移。 在通过手术进入口插入之后，可以横向加宽一个或多个牵开器叶片，以使牵开器叶片的远端基本上间隔开，以在外科手术过程中最大程度地接触组织的大部分区域以移动。 在完成手术过程之后，可以通过将叶片嵌套在一起而使收缩器叶片变窄，并且牵开器可以容易且安全地从进入端口撤出。

摘要： An improved valve cutter for in-situ incision of valve leaflets which safely, efficiently, and consistently renders venous valves incompetent while minimizing frictional forces on the endothelium of the vessel and preventing inadvertent contact between cutting surfaces and the intima of the vein wall. The valve cutter includes a plurality of proximally directed prongs presenting sharp edges, where the prongs are separated by slots similarly presenting sharp edges to pierce the valve leaflets so that the cutting head is provided with a continuous cutting surface in multiple planes running along the entire forward edge of the cutting head. Fiber optics provided for viewing the valves as they are penetrated by the sharp cutting edges.
