摘要:
Removable guide tips are pre-assembled into threaded holes of a fracture fixation plate. The guide tips may be used with or without drill guides to guide a drill along the axes of threaded holes defined in the plate. In addition, the tips may be used with bending tools to contour the plate laterally, longitudinally and with twist. More particularly, such plate contouring can be performed while the plate is located on the bone.

A fracture fixation plate system for use on a long bone having a metaphysis and a diaphysis, includes at least one end plate having a head portion for the metaphysis, and at least one diaphyseal plate having a first end and a second end with a plurality of screw holes therebetween. The end plate includes mating structure adapted to mate with and securely couple to at least one end of the at least one diaphyseal plate. The system preferably includes several end plates and diaphyseal plates to accommodate anatomy of various sizes. A method for coupling the plates to the bone is also provided.

A torque-limiting fastener driver for driving a bone fastener into bone includes a handle supporting a driver shaft. The driver shaft includes limited components which are designed to provide feedback to a user regarding the applied torsional force. In addition, the driver shaft is designed to controllably fail before any potential uncontrolled failure of the distal driving tip. This prevents application of too much torque and controlled design of the shape and size of the failed components.
摘要:
A method for fastening a two-piece surgical fastener to bodily tissue whereby the surgical fastener has a safety position. The method comprises inserting first and second piercing posts through at least two layers of tissue and attaching a receiving portion to the coupling ends of the first and second piercing posts. Each of the first and second piercing posts have a fixed end and a coupling end, the first piercing post being fixedly-attached at its fixed end to a first base portion, the second piercing post being fixedly-attached at its fixed end to a second base portion, the first and second base portions being foldably coupled to one another by a hinge, where a bias device imparts a bias force on at least one of the first base portion and the second base portion in a direction toward the other and substantially perpendicular to a longitudinal axis of the hinge.

Surgical clips, which are particularly useful in the transoral invagination and fundoplication of the stomach to the esophagus, and methods of applying the surgical clips to living tissue are disclosed. The clips include first and second arms joined by a bridge to form a substantially U-shape, and which are provided with a first structure adapted to prevent a movement of the clip in a direction perpendicular to a longitudinal axis of the clip after the clip is applied to tissue. In addition, the clips preferably also include a second structure adapted to prevent rotation of the clip about the longitudinal axis of the clip after the clip is applied to tissue.
摘要:
A system for the internal fixation of a fractured bone of an elbow joint of a patient includes at least one bone plate, each bone plate having a plurality of holes and generally configured to fit an anatomical surface of the fractured bone. The at least one plate is adapted to be customized to the shape of a patient's bone. The system also includes a plurality of fasteners including at least one locking fastener for attaching the bone plate to the bone. At least one of the holes is a threaded hole. Guides for plate benders, drills, and/or K-wires can be pre-assembled to the threaded holes, and the locking fastener can lock into any of the threaded holes after the guides are removed.

An apparatus for the transoral invagination and fundoplication of the stomach to the esophagus includes a clip applier having sharp toothed jaws for grasping and damaging the fundus prior to applying the clip. The clip applier has an overall diameter of less than 7 mm. The clip applier jaws are coupled to a pull wire via a linkage which increases the mechanical advantage and thus permits greater grasping force. A plurality of clip designs are also provided.
摘要:
A surgical instrument includes an end effector having a clevis and first and second jaws mutually rotatable between open and closed positions. The jaws are proximally directed and laterally displaced relative to a longitudinal axis of a control shaft of the instrument. The jaws hold first and second parts of a fastener, respectively. The first part includes a base having upstanding tissue piercing posts, and the second part includes another base defining apertures for receiving the posts, as well as a portion movable relative to the second base. When the upstanding posts are inserted into the apertures, the movable portion can be moved into a second configuration to lock the parts of the fastener together. The instrument is adapted to move the second part into the second configuration. A method for using the apparatus and fastener are also provided.
