Abstract

Claims (26)

1. An apparatus comprising:

a chassis;

a cover coupled to the chassis;

a lever supported by the chassis and positioned partially within the cover, the lever being rotatable about a first axis relative to the chassis, the lever having a first lever arm, a second lever arm, a first protrusion extending outward in a proximal direction relative to the cover from the second lever arm, a third lever arm, and a second protrusion extending outward in the proximal direction relative to the cover from the third lever arm, the first protrusion and the second protrusion being configured to receive a manual input, the second lever arm having a slotted portion; and

a drive element supported by the chassis and positioned between the first axis and at least one of the first protrusion or the second protrusion, the drive element being translatable relative to the chassis along a second axis that is perpendicular to the first axis in response to the manual input, the drive element engaged being with and extending through the second lever arm.

2. The apparatus of claim 1 , wherein:

the first lever arm and the second lever arm intersect at the first axis; and

the first lever arm extends from the second lever arm at a non-zero angle.

3. The apparatus of claim 2 , wherein:

the third lever arm extends from the first lever arm opposite of the second lever arm.

4. The apparatus of claim 3 , wherein:

the third lever arm and the second lever arm are longitudinally aligned perpendicular to the first axis.

5. The apparatus of claim 3 , wherein:

the third lever arm and the second lever arm are longitudinally misaligned.

6. The apparatus of claim 1 , further comprising:

an arm supported by the chassis, the arm rotatable relative to the chassis about a third axis, a longitudinal axis of the arm extending perpendicular to the third axis, the arm including a first guide structure, the first guide structure having a length extending radially relative to the third axis, wherein:

the third axis is perpendicular to the first axis,

the first lever arm includes a second guide structure at an end opposite the first axis, and

the second guide structure is engaged with and translatable along the length of the first guide structure.

7. The apparatus of claim 6 , further comprising:

an actuator operably coupled to the arm and configured to affect a rotation of the arm about the third axis.

8. The apparatus of claim 1 , further comprising:

an end effector operably coupled the drive element; and

wherein the at least one of the first protrusion or the second protrusion provides a visual indication of an operative position of the end effector.

9. The apparatus of claim 1 , wherein:

a length of the slotted portion affects a range of motion of the drive element.
