Abstract
A forceps device includes forceps deployable through a needle. In one embodiment, both jaws of the forceps are movable with respect to each other, and their movement is controlled by a box slider. In another embodiment, one jaw is fixed and the other jaw is movable. In one embodiment the jaws include teeth that increase in length from the proximal end of the jaws to the distal end of the jaws. In a further embodiment, suction may be achieved through the needle when the forceps are removed.
Claims37
A forceps device comprising:
- a first jaw;
- a second jaw opposed to and rotationally connected to the first jaw by a clevis;
- a first linking piece rotationally connected to the first jaw;
- a second linking piece rotationally connected to the second jaw;
- and
- a box slider rotationally connected to both the first and second linking pieces,
- wherein moving the box slider distally causes the first and second jaws to rotate to an open position, moving the box slider proximally causes the first and second jaws to rotate to a closed position, and the jaws are deployable from within a needle.
A forceps device comprising a first fixed jaw and a second jaw movable relative to the first jaw, wherein the jaws are deployable from within a needle.
A forceps device, comprising:
- a first jaw having
- a first tooth;
- a second tooth distal to and longer than the first tooth,
- a third tooth distal to and longer than the second tooth,
- a fourth tooth distal to and the same length as the third tooth,
- a fifth tooth distal to and longer than the fourth tooth,
- a sixth tooth distal to and longer than the fifth tooth,
- a seventh tooth distal to and longer than the sixth tooth, and
- an eight tooth distal to and longer than the seventh tooth;
- and
- a second jaw having
- a first tooth longer than first tooth of the first jaw;
- a second tooth distal to and the same length as the first tooth,
- a third tooth distal to and longer than the second tooth,
- a fourth tooth distal to and longer than the third tooth,
- a fifth tooth distal to and longer than the fourth tooth,
- a sixth tooth distal to and longer than the fifth tooth,
- a seventh tooth distal to and longer than the sixth tooth, and
- an eight tooth distal to and the same length as the seventh tooth.
A histology and cytology device comprising:
- a forceps apparatus deployable from within and removable from the bore of a needle;
- and
- a suction device;
- wherein suction may be achieved through the bore of the needle when the forceps apparatus is removed.
A forceps device comprising:
- a first jaw and a second jaw opposed to the first jaw, the first and second jaws having a plurality of teeth, wherein at least one tooth of the plurality of teeth comprises a plurality of sub-tooth layers.
