Disposable bidirectional ratchet
A disposable bidirectional ratchet, which has a tubular hollow handle with an interior surface having teeth thereon; a toggle mounted movably within the handle; a knob connected to an end of the toggle moves the toggle inside the handle; a plurality of pins on another end of the toggle; a plurality of actuators each comprising: fingers, levers, toes and a head, and having a post guide formed therein; a plurality of posts affixed to a clutch; and, wherein the actuators are movable affixed to the clutch via the posts, and the pin position selects the direction of engagement via adjustment of the actuator position via applying force to the levers, which moves the lateral edges of the actuator towards or away from the teeth.
1. A disposable bidirectional ratchet designed to be disposed of after use and not sterilized, the bidirectional ratchet comprising:
a handle comprising a tubular front body affixed to a tubular back body;
the tubular front body comprising an interior wall, said interior wall comprising teeth extending periodically from the interior wall;
a toggle within the handle, said toggle comprising a hollow elongated member;
a knob that moves the toggle;
a plurality of pins with longitudinal axes parallel to a longitudinal axis of said handle on an end of the toggle;
a plurality of actuators, each actuator comprising:
fingers, levers, toes, a head, and a post guide formed in the actuator;
a plurality of posts affixed to a clutch; and,
wherein the actuators are movably affixed to the clutch via the posts, and the pin position selects the direction of engagement via adjustment of the actuator position via applying force to at least one of the levers of each actuator, which moves each of the fingers of each actuator towards or away from each of the teeth.
2. The disposable bidirectional ratchet according to claim 1 , wherein each finger of each actuator comprises an obtuse side, an engaging side, and a neutral side.
3. The disposable bidirectional ratchet according to claim 2 , wherein when the pins are in a first location, the pins apply a force to at least one of the levers such that each of the actuators pivot into a first position, and
when the handle is turned in a first direction, rotational force is applied in the opposite direction by the engaging side of each of the actuators.
4. The disposable bidirectional ratchet according to claim 2 , wherein when the pins are in a second location, the pins apply a force to at least one of the levers such that each of the actuators pivot into a second position, and when the handle is turned in a second direction, rotational force is applied in the opposite direction by the engaging side of each of the actuators.
5. The disposable bidirectional ratchet according to claim 3 , wherein the engaging side of at least one of the fingers of each actuator abuts at least one of the teeth, and a toe not adjacent to the engaging side abuts a rib of the clutch.
6. The disposable bidirectional ratchet according to claim 4 , wherein the engaging side of at least one of the fingers of each actuator abuts at least one of the teeth, and a toe not adjacent to the engaging side abuts a rib of the clutch.
7. The disposable bidirectional ratchet according to claim 5 , wherein when the handle is turned in a direction opposite the first direction, each finger slides over the at least one of the teeth without catching.
8. The disposable bidirectional ratchet according to claim 6 , wherein the pins are configured to apply a force to at least one of the levers such that once the finger slides over the at least one of the teeth, the engaging side is in contact with that tooth.
9. The disposable bidirectional ratchet according to claim 2 , wherein when the pins are in a third location, the pins do not apply a force to the levers.
10. The disposable bidirectional ratchet of claim 1 , wherein said hollow elongated member of said toggle comprises a distal end with rib catches and a proximal end comprising a flat surface supporting said plurality of pins.
