摘要： A rigidizable surgical instrument comprises a rigidizable member, a first collapsible arm, a second collapsible arm, and a specimen retrieval bag for retrieving biological materials. The collapsible arms may be located at the distal end of the rigidizable member. The specimen retrieval bag may have an open end and a closed end, and may be configured to be retained upon the collapsible arms. The rigidizable member may include a rigidizing component to rigidize the rigidizable member when the state-change material or a stiffening element is in a rigid state. The rigidizable member may be rendered substantially rigid when the rigidizing component is actuated and the rigidizable member may be rendered substantially flexible when the rigidizing component is deactuated. A rigidizing mechanism for actuating the rigidizing component may include a vacuum. Various end-effectors may be provided in addition to the specimen retrieval bag.

摘要： An apparatus for guiding an instrument inserted through an endoscope's instrument channel is provided. The apparatus can attach to an endoscope to guide the position of the end of the instrument, such as by constraining the instrument to bend in a predetermined manner, or otherwise guide the distal end of the instrument extending from the distal end of the instrument channel. The apparatus can be used to assist in positioning the instrument to perform useful work on tissue adjacent the perimeter of the endoscope. The apparatus can also be used to provide cooperation between instruments inserted either through or alongside the endoscope.

摘要： In accordance with the present invention there is provided a surgical instrument for the removal of biological material through an opening within a patient, wherein biological material being larger than the opening within the patient. The surgical instrument includes a specimen retrieval bag having at least one wall. The specimen retrieval bag has an open end, a closed end and a longitudinal axis extending therebetween, wherein the open end is for receiving biological materials therein. The instrument further includes at least one material transfer member attached to the wall adjacent to the open end. The material transfer member extends radially from the wall and is in fluid communication with the bag. Wherein when the open end of the bag is removed from the patient through the opening and the material transfer member is at least partially removed therethrough, a portion of the biological material moves from a portion of the bag within the patient to a portion of the material transfer member outside of the patient to reduce the size of the biological material within the patient.
