Abstract: A surgical tissue retrieval instrument has a collapsible pouch at the distal end of an elongated pusher rod that is introduced into a patient through a cannula. The instrument includes a two-jaw fork that forms a loop when in an unconstrained configuration and that supports the pouch. Deployment and operation of the fork and the pouch are controlled by a securing mechanism. The two jaws and the securing mechanism are slid in a hem surrounding the opening of the pouch when the device is assembled.

Abstract: A tissue retrieval bag is provided, comprising a region of the bag defining an opening; a pleated fold intersecting said opening at a distal region of the opening; and a hem circumferentially formed around said opening, the hem forming insertion points adapted to receive a draw string, the insertion points in direct opposition to the pleated fold.

Abstract: A surgical tissue retrieval instrument has a collapsible pouch at the distal end of an elongated pusher rod that is introduced into a patient's abdomen through a cannula. The instrument includes a two-jaw fork that forms a loop when in an unconstrained configuration and that supports the pouch. Deployment and operation of the fork and the pouch are controlled by a toggle means. The two jaws and the toggle means are slid in a hem surrounding the opening of the pouch when the device is assembled. An especially advantageous embodiment features two jaws of unequal length.

Abstract: A device is disclosed for use in for example obtaining a soft tissue biopsy sample from a patient. In one embodiment the device comprises an outer needle 16 and a sampling needle 18 in coaxial relationship, a handle 34 to which one of the needles e.g. the sampling needle is secured, and a lever arm 36 arranged to enable the other needle e.g. the sample needle 18 to be moved slidingly over the one needle. A spring 40 is arranged to bias the lever arm 36 and hence the sample needle 18 to a predetermined position. In use the needles 16,18 are inserted into a patient and a portion of tissue is trapped in a slot cut into an end portion of the sampling needle 18 as the outer needle 16 slides fully over the sampling needle. The portion of tissue is removed from the device by releasing a catch 38 which causes the outer needle 16 to be drawn back under the influence of the spring to expose the slot in the sampling needle.

Abstract: A hinged disposable container for retaining surgical implements is disclosed. The container is provided with one or more elongated strips of a resilient material. The surgical implements are retained by inserting them into slots formed in the strip, and numerical indications enable the user to precisely determine the number of needles in the container. Separate adhesive means are provided for holding other sharps in position.
