| Summary: | The present invention relates to surgical devices and more particularly to endoscopic retrieval devices constructed for retrieving relatively small pieces of sample tissue or foreign bodies from a human subject through orifices or small incisions.
An endoscopic surgical device for retrieving severed tissue or foreign bodies from within a subject is disclosed. The device comprises a support unit and a tissue retrieving net system. The net system is carried by the support unit and may be inserted into the subject through an orifice or small incision and operated to retrieve tissue that has been severed by a conventional method. The net system comprises a net, a net actuator, a net deployment and retrieval assembly for transmitting motion between the net and its actuator. The net system further comprises at least one net connector disposed such that only one connector is within an articulation zone, defined by locations of severe bending of the device during operation. |
