摘要： A blade actuating assembly is provided which permits selective reciprocal movement of a tissue cutting blade positioned at a distal end of an optical trocar assembly from a non-deployed position to a deployed position and back to a non-deployed position. The trocar assembly has an optical obturator which includes a sleeve having a longitudinal bore between a proximal end and a distal end. The longitudinal bore of the sleeve is configured to receive at least a portion of an endoscope or like image transferring system. An objective optical member, such as an optical window is positioned at the distal end of the sleeve and is provided to permit optical images to pass into the longitudinal bore of the sleeve and to permit illumination light to pass to the surgical site.

摘要： A device for positioning a surgical instrument having an elongated portion, the device comprising a housing having an opening therethrough to receive the elongated instrument portion and an actuation member mounted to said housing and movable between a first position and a second position. The actuation member overlaps a portion of said opening in said second position to prevent movement of the elongated portion of the instrument. The actuation member may be movable along a plane parallel, perpendicular or lateral to a longitudinal axis of the surgical instrument.

摘要： A fastener for securing adjacent layers of body tissue to each other and being configured and composed of a material so as to emerge from the body tissue after a limited period of time. The fastener includes a backspan and at least two prongs extending from the backspan. Each prong has a tapered tip culminating in a sharp point. The prongs each include a shaft having a cylindrical portion of uniform diameter. In one embodiment, the prong includes a serrated portion having a plurality of notches spaced apart so as to define ridge portions there between. In another embodiment, the prong includes a pair of tapered projecting surfaces extending around a portion thereof.
