Abstract
An endoscopic instrument having one or two moving jaws. One or two control wires attach to the lower portion of the moving jaws. Each control wire is located within a groove or enclosed channel which passes along the side and preferably to the back of the jaw. The end of the control wire is connected with the jaw so that when the control wire is moved, the force from the wire moved the jaw about its pivot point. If two moving jaws are present, the pivot point is preferably centrally located in the housing. If only a single moving jaw is used, the pivot point may be central, or it may be offset.
Claims24
An endoscopic instrument, comprising:
- a sheath having a proximal end a distal end and a channel extending therethrough, said channel being generally centered within said sheath,
- a housing connected with said distal end of said sheath,
- a handle connected with said proximal end of said sheath,
- a first jaw having a pivot point, said first jaw having an open position and a closed position,
- a channel in said first jaw, said channel passing along a side of said first jaw,
- a second jaw,
- and an actuation wire having a proximal end, a distal end and a distal portion, said proximal end of said actuation wire being connected with said handle, said distal end of said actuation wire being connected with said first jaw at a connection point distal to said pivot point, said distal portion of said actuation wire located within said channel in said first jaw, said actuation wire extending through said channel in said sheath,
- wherein when said actuation wire is moved longitudinally along a body of the instrument, said first jaw moves between the open position and the closed position.
An endoscopic instrument, comprising:
- a sheath having a proximal end and a distal end,
- a housing connected with said distal end of said sheath,
- a handle attached to said proximal end of said core wire,
- a first jaw being pivotable around a pivot point, said first jaw having an open position and a closed position,
- a first channel in said first jaw, said first channel passing along a side of said first jaw,
- a second jaw being pivotable around said pivot point, said second jaw having an open position and a closed position,
- a second channel in said second jaw, said second channel passing along a side of said second jaw,
- a first actuation wire having a proximal end, a distal end and a distal portion, said proximal end of said first actuation wire being connected with said handle, said distal end of said actuation wire being connected with said first jaw at a connection point distal to said pivot point, said distal portion of said first actuation wire being located within said first channel in said first jaw,
- and a second actuation wire having a proximal end, a distal end and a distal portion, said proximal end of said second actuation wire being connected with said handle, said distal end of said second actuation wire being connected with said second jaw at a second connection point distal to said pivot point, said distal portion of said second actuation wire being located within said second channel in said second jaw,
- wherein when said first and second actuation wires are actuated, said first and second jaws move between the open position and the closed position.
