Abstract
A clip applier having a handle at a proximal portion, an elongated portion extending distally of the handle, a jaw mechanism including a pair of jaws movable to a closed position to crimp a clip held therein, a clip feeder mechanism movable in proximal and distal directions, a camming mechanism and a puller mechanism movable in proximal and distal directions. The puller mechanism is operatively connected to the handle such that actuation of the handle a) moves the puller mechanism a first distance in the proximal direction; and b) moves the clip feeder mechanism a second distance greater than the first distance.
Claims20
A surgical clip applier comprising:
- a handle at a proximal portion;
- an elongated portion extending distally of the handle;
- a jaw mechanism at a distal portion, the jaw mechanism including a pair of jaws movable to a closed position to crimp a clip held therein;
- a camming mechanism;
- a clip feeder mechanism movable in proximal and distal directions;
- and
- a puller mechanism movable in proximal and distal directions, the puller mechanism operatively connected to the handle such that actuation of the handle a) moves the puller mechanism a first distance in the proximal direction;
- and b) moves the clip feeder mechanism a second distance in the proximal direction, the second distance being greater than the first distance.
A laparoscopic surgical clip applier comprising:
- a handle at a proximal portion;
- an elongated portion extending distally of the handle;
- a jaw mechanism at a distal portion, the jaw mechanism including a pair of jaws movable to a closed position to crimp a clip held therein, the jaw mechanism insertable through a trocar cannula without a clip positioned in the jaws;
- a puller mechanism operatively connected to the handle;
- a camming mechanism operatively connected to the puller mechanism for proximal movement to close the jaws;
- and
- a clip feeder mechanism movable in proximal and distal directions, wherein proximal movement of the camming mechanism to close the jaws effects distal movement of the clip feeder mechanism to feed a clip into the jaws.
A laparoscopic surgical clip applier dimensioned for insertion through a five millimeter trocar cannula comprising:
- a handle at a proximal portion;
- an elongated portion extending distally of the handle;
- a jaw mechanism at a distal portion, the jaw mechanism including a pair of jaws insertable through the trocar cannula without a clip positioned in the jaws and movable from an open position to a compressed position by the trocar cannula during insertion through the trocar cannula;
- a puller mechanism operatively connected to the handle;
- a camming mechanism operatively connected to the puller mechanism and movable with respect to the jaws to crimp a clip held therein;
- and
- a stroke increasing mechanism;
- wherein due to the stroke increasing mechanism, movement of the handle moves the puller mechanism a first distance to move a clip feeder a second distance in a reverse direction, the second distance being greater than first distance, and further retracts the camming mechanism to close the jaws.
