<p>A surgical distractor for distracting a joint space to facilitate passage of a surgical tool. The distractor includes a first arm, a second arm, a coupling device, and a limit device. Each arm includes a handle portion and a flange. The coupling device pivotably couples the first and second arms such that the flanges combine to define a passage. A size of the passage increases when transitioning the distractor from a first state of expansion to a second state of expansion. The limit device is associated with the arms for selectively preventing transitioning of the distractor from the second state of expansion to the first state of expansion. In some embodiments, the flanges, and thus the passage, is laterally and/or angularly offset from the handle portions.</p> |
