摘要:
The present invention relates to an instrument for tightening elongated wound closure elements around body tissue (10). In particular, an instrument for tightening wound closure elements around a human sternum following surgery. The instrument includes a first handle (20) and a second handle (22) pivotally attached to the first handle and movable between an open and a closed position. A retaining system (23, 24) is also provided to tighten wound closure material in response to movement of the second handle.

A surgical apparatus (10) for tightening a strap loop (12) to a predetermined tension about split tissue portions includes a frame (16), an advancing mechanism for tightening the strap loop, a linkage mechanism which severs excess strap material not used in securing the tissue portions together and a control mechanism for controlling operation of the apparatus. The advancing mechanism includes a tensioning lever (18) and a gear mechanism. The gear mechanism includes a tensioning hub (36) and a clutch (38) which releases when the tension in the strap loop exceeds a predetermined value. The control mechanism includes a safety feature for preventing inadvertent activation of the linkage mechanism. A buckle and a method for use with the surgical apparatus is also disclosed. The invention is particularly contemplated for repair of the human sternum when the sternum has been split during surgical procedures.
摘要:
An apparatus (10) for applying a buckle assembly (14) about split portions of tissue is provided. The apparatus (10) is particularly contemplated for use with a buckle (14) of the type having a base member (38) with an opening (44) extending generally transversely therethrough for reception of a first strap end portion and a clamp member (40) slidably housed within a channel (42) formed in the base member (38). The apparatus (10) includes a frame member (16), a mechanism (24) disposed in a lower surface of the frame member (16) for releasably supporting the buckle member (14) and a mechanism (18,22) associated with the frame member for advancing the clamp member (40) within the channel (26) of the buckle (14) to a strap securing position wherein the strap member (12) is secured within the buckle member (14) in a looped configuration about the tissue portions.

A strap assembly (10) to be looped about split portions (50) of human tissue to retain the split portions in adjacent contacting relation to promote healing thereof is provided. The strap assembly includes a flexible strap member (12) and a buckle member (14) to secure the strap member. The buckle member includes a base member (16) having an opening (18) extending therethrough for reception of the strap member and a clip member (20) pivotally mounted to the base member for engaging the strap member. The clip member is adapted to pivot from an open position to allow for reception of the strap member through the opening and a closed position wherein the strap is engaged by and wedged between a forward edge (27) of the clip member and the base member to secure the strap member around the split portions of tissue.

A surgical device (10) is described herein that can be used to fire different types and sizes of disposable loading units (30, 45, 60). In a preferred embodiment, the device applies parallel rows of surgical fasteners to body tissue and concomitantly forms an incision between the rows of staples during an endoscopic or laparoscopic surgical procedure. The device can be utilized with disposable loading units configured to apply linear rows of staples measuring from about 15mm in length to about 60mm in length and can be used to fire disposable loading units containing surgical clips and individual staples.
