Abstract
A surgical device comprises an ex vivo magnet and an in vivo sled magnetically attracted to the ex vivo magnet. The sled can be positioned and anchored within a patient by moving the ex vivo magnet. The sled defines a longitudinal axis. An arm extends from the sled. The arm being moveable relative the sled between a retracted position and an extended position. The arm comprises an end effector. A locking mechanism operatively connected to the arm to lock the arm in the retracted and extended positions. The mechanism may include a rack that both rotates about a pinion and translates tangentially about the pinion.
Claims14
A surgical device, comprising:
- a) an ex vivo magnet;
- b) an in vivo sled magnetically attracted to the ex vivo magnet, whereby the sled can be positioned and anchored within a patient by moving the ex vivo magnet, the sled defining a longitudinal axis;
- c) an arm extending from the in vivo sled, the arm being moveable relative the sled between a retracted position and an extended position, the arm comprising a surgical end effector;
- and
- d) a rack and pinion operatively connected to the arm to lock the arm in the retracted and extended positions.
(canceled)
A surgical device, comprising:
- a) an anchor;
- b) a sled magnetically attracted to the anchor whereby the sled can be positioned within a patient by moving the anchor;
- c) an arm extending from the sled, the arm being moveable relative the sled between a retracted position and an extended position, the arm comprising a surgical end effector;
- and
- d) a rack and pinion operative to both actuate the arm between the retracted and extended positions and lock the arm in the retracted and extended positions.
A surgical device, comprising:
- a) an arm extending from a base, the arm pivoting relative the base about an axis between a first position and an second position, the arm comprising a surgical end effector;
- b) a pinion rotatable about the arm pivot axis;
- c) a track tangential the pinion, the track connected to the arm and rotatable about the arm pivot axis as the arm pivots;
- d) a rack engaging the pinion and translatable along the track;
- e) a first relief in the base dimensioned to receive the rack, the first relief being aligned with the track when the arm is in the first position;
- and
- f) a second relief in the base dimensioned to receive the rack, the second relief being aligned with the track when the arm is in the second position.
