Abstract
A surgical apparatus for removing fasteners from the body includes an endoscopic portion for insertion through an endoscopic tube and a fastener removing assembly positioned at the distal end of the endoscopic portion. By engaging a fastener with the fastener removing assembly, a surgeon can actuate the assembly and cause the fastener to distort to a configuration suitable for removal from the body.
Claims26
A surgical apparatus for removing from the body a fastener having a pair of legs joined by a backspan having top and bottom portions, the apparatus comprising:
- a) an endoscopic portion;
- b) means positioned at a distal end of said endoscopic portion for removing the fastener, said fastener removing means comprising a stationary member and a movable member, wherein said movable member comprises parallel spaced apart fork means for engaging said backspan;
- and
- c) means remote from said distal end of said endoscopic portion for actuating said fastener removing means;
- wherein said movable member engages the fastener backspan bottom portion and proximal movement of said movable member moves said fastener proximally to cause said fastener backspan top portion to press against said stationary member further causing said fastener to deform to a configuration suitable for removal.
A surgical apparatus for removing from the body a fastener having a pair of legs joined by a backspan having top and bottom portions, the apparatus comprising:
- a) an endoscopic portion;
- b) means positioned at a distal end of said endoscopic portion for removing the fastener, said fastener removing means comprising a stationary member and a movable member, wherein said stationary member comprises parallel spaced apart fork means for engaging said backspan;
- and
- c) means remote from said distal end of said endoscopic portion for actuating said fastener removing means;
- wherein said stationary member engages the fastener backspan bottom portion and distal movement of said movable member causes said movable member to press against said fastener backspan top portion further causing said fastener to deform to a configuration suitable for removal.
A surgical apparatus for removing from the body a fastener having a pair of legs joined by a backspan, the apparatus comprising:
- a) an endoscopic portion;
- b) means positioned at a distal end of said endoscopic portion for removing the fastener, said fastener removing means comprising a stationary member and a movable member, wherein said movable member moves longitudinally along a longitudinal axis of said endoscopic portion and wherein one of said members comprises parallel spaced apart forks;
- and
- c) means remote from said distal end of said endoscopic portion for actuating said fastener removing means.
A surgical apparatus for removing from the body a fastener having a pair of legs joined by a backspan, the apparatus comprising:
- a) an endoscopic portion comprising an outer tube and an inner rod slidably disposed therein;
- b) means positioned at a distal end of said endoscopic portion for removing a fastener, said fastener removing means comprising parallel spaced apart forks;
- and
- c) means remote from said distal end of said endoscopic portion for actuating said fastener removing means, said actuating means comprising a handle assembly having at least one pivotable handle and wherein said inner rod is secured to said at least one pivotable handle.
A surgical apparatus configured and dimensioned for insertion through a cannula comprising:
- a) an endoscopic portion comprising an outer tube and an inner rod slidably disposed therein;
- b) tool means positioned at a distal end of said endoscopic portion, said inner rod cooperating with said tool means;
- c) means remote from a distal end of said endoscopic portion for manipulating said inner rod;
- and
- d) means for locking said inner rod in a fixed position, said locking means comprising a latching member slidable in a direction substantially perpendicular to said endoscopic portion and engaging said inner rod.
A surgical apparatus for removing from the body a fastener having a pair of legs joined by a backspan, the apparatus comprising:
- a) an endoscopic portion;
- b) means positioned at a distal end of said endoscopic portion for removing the fastener, said fastener removing means comprising a stationary member and a movable member, wherein said movable member moves longitudinally along a longitudinal axis of said endoscopic portion;
- c) actuating means positioned at a proximal end of said endoscopic portion for actuating said fastener removing means;
- and locking means disposed in said actuating means for locking said movable member in a fixed position.
