Venous valve cutter

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.

Reservoir for enclosing and retrieving body specimens

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the retractor blades can be narrowed by nesting the blades together and the retractor can be easily and safely withdrawn from the access port.
