Abstract
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.
