Abstract
A bone hook having a displaceable jaw is provided. The hook includes a rod receiving portion and main body with a jaw defining a slot for receiving a bone, and an actuator configured to vary the dimension of the slot. The actuator is configured to translate a rotation into an adjustment of a height of the slot thereby gripping or clamping a pedicle, lamina, or transverse process bone between the jaw and main body.
Claims17
A bone hook assembly adaptable to engage any one of a plurality of pedicle, lamina, or transverse process bones, each of the plurality of pedicle, lamina, or transverse process bones being dimensioned different than the other, the bone hook assembly comprising:
- a main body having a rod receiving portion;
- a jaw spaced apart from the main body so as to define a slot for receiving one of the plurality of pedicle, lamina, or transverse process bones, wherein the slot has a height;
- an actuator configured to adjust the height of the slot;
- a pair of tabs on the jaw;
- and
- a receiving portion having elongated slots;
- wherein the actuator is configured to translate a rotation into an adjustment of the height of the slot;
- and
- wherein the receiving portion is configured to slidingly receive the jaw wherein the pair of tabs are configured to slide into a respective elongated slot.
