摘要:
Improved spinal instruments are provided. In particular, the present application relates to an improved rongeur that allows for multiple bites of bone to be performed in a patient before removing the rongeur from the patient. The rongeur includes a lower shaft and an upper shaft slidable relative to the lower shaft. The lower shaft and upper shaft form a jaw mechanism that can take multiple bites of bone, which can be deposited in a storage cavity formed in the upper shaft. To assist in removing the bone from within the storage cavity, an internal plunger mechanism can be provided that is actuated by a finger hold. In addition, at least portions of the upper shaft are detachable from the lower shaft such that the upper shaft can be thoroughly cleaned and re-used if desired.
