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.

Methods of the invention include delivering a grasper, a clip applier, and an endoscope transorally to the site of fundoplication; grasping the fundus with the grasper (or similar device, e.g. corkscrew) and pulling it into the jaws of the clip applier; closing the jaws of the clip applier over the fundus and applying a clip to the fundus.

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 medical method includes sliding two substantially straight unconnected arms over a fold of body tissue such that a first arm contacts a first portion of the fold and a second arm contacts a second portion. Then, each arm is bent completely through the fold such that both of the arms compress the portions of the fold into contact with each other. Another method includes releasably coupling first and second substantially linear arms to a bridge, each of the arms having a substantially straight sliding portion and a bendable piercing portion. The arms are slid over opposing sides of two body tissue layers, the first arm sliding over the first layer and the second over the second layer. While the sliding portions of the arms remain substantially straight, each piercing portion is bent completely through the adjacent layer and halfway through the other layer to compress the two layers together.

Methods and apparatus for delivering a medical instrument over the exterior of an endoscope while the endoscope is installed in the patient's body allow the use of instruments which are too large to fit through the lumena of an endoscope. Furthermore, the invention allows the elimination of working lumena in an endoscope thereby minimizing the likelihood of contamination.
摘要:
An endoscopic needle assembly has an inner tube formed from a close-wound coil of wire surrounded by a sheath, an outer tube surrounding the inner tube such that the inner tube can move longitudinally relative to the outer tube, a needle joined to a distal end of the inner tube, and a two piece handle having a first handle piece attaching to the inner tube and a second handle piece attaching to the outer tube. A safety shield, formed from a plurality of hinged petals, is built onto the distal end of the outer tube to protect an endoscope from inadvertent penetration by the needle.

A surgical instrument for applying sutures to tissue includes a needle deployment mechanism and a catch mechanism. In some embodiments, the needle deployment mechanism employs a linear path. Alternatively, it can employ a curved needle. The surgical instrument may include a rotatable head, a bend, and/or a malleable elongated body member formable into various shapes.

A surgical tool attaches to the distal end of an endoscope and provides a rotatable treating element. According to one embodiment of the invention, the treating element is a pair of jaws provided with cautery capability. According to an aspect of the invention, the treating element is capable of multiple movements from a first closed position, to an open position, to a second closed position and back to the first closed position via a single controller with a single linear movement.
