    摘要: A retraction device for retracting an incision in a body wall includes a sheath that traverses through the incision from outside the body to a body cavity inside the body. The retraction device may include a deployable, adjustable frame that supports the sheath and that, together with the sheath, retracts the incision. The retraction device may include an outer ring and an inner ring coupled to opposing ends of the sheath and further include means to place the sheath in tension between the inner and outer rings, thereby retracting the incision.

    摘要: The invention relates to a tissue morcellator for minimally invasive surgery. The morcellator has a metallic cutting ring mounted on a visually transparent hollow cylinder, which in combination with a visually transparent outer morcellator tube enables a surgeon to visualize the inside of the morcellator shaft for detection of loose tissue fragments in the device. A tenaculum used with the morcellation device has a spacer for preventing contact with the blade. The cutting tube can oscillate, rather than rotate, along the longitudinal axis of the cutting tube. The morcellator utilizes an extendable tissue guide on the outer tube of the morcellator shaft for preventing the tissue from rotating along the longitudinal axis of the morcellator tube. This allows the tissue to be continuously rotated into the morcellator device for continuous peel. The tissue guide can also be fully retracted to allow for coring of the bulk tissue.

    摘要: A clip applier for applying a surgical clip in a patient comprising a disposable cartridge and a reusable actuating mechanism. The cartridge includes an elongate tube having a proximal end and a distal end, a pair of opposing jaw members extending outwardly from the distal end of the elongate tube, and a one-way ratchet mechanism providing a full actuating stroke. The actuating mechanism is coupled to the proximal end of the elongate tube to move the jaw members between an open position and a closed position. The ratchet mechanism may be formed from injection molded plastic. The cartridge further comprises a push member for advancing the clip into the jaw members, a biasing spring for maintaining the push member against the clip, and a drive coupling operatively connected to a sliding ratchet pawl for engaging with mating teeth formed on an inner surface of the elongate tube, wherein the ratchet pawl includes a cantilever arm that engages with the mating teeth, and wherein the drive coupling provides a central connection of the ratchet pawl allowing pivoting and improved seating of the mating teeth. A method of applying a surgical clip to an object in a patient using the clip applier of the invention includes the steps of positioning the clip applier within the patient such that the jaw members are adjacent to the object to be clipped, closing the jaw members and the clip over the object, and removing the clip applier from the patient. The method may further comprise the steps of orienting the clip applier such that the jaw members pass over the object, manipulating the jaw members to move the object to a compressed state within the jaw members, advancing the clip over the object to maintain the object in the compressed state, and retracting a feeder to allow the next clip to be fed into the jaw members.
