Abstract
This invention relates to a set of surgical instruments for use in reattachment of a cranial flap using a cranial clamp having a base, a cap and a stem. The set of surgical instruments includes an applier instrument, a stem holder instrument and a stem cutter instrument. The applier instrument slidably receives a portion of the stem and moves the cap relative to the base. The applier instrument includes a handle, a trigger and a barrel configured as a gun-style instrument, as well as includes an engagement mechanism having a contoured surface that matingly engages a contoured surface on a portion of the stem. The stem holder instrument engages and holds a portion of the stem. The stem holder instrument includes a pair of handles and a lock mechanism that may be locked upon squeezing a pair of handles once and be opened upon squeezing the pair of handles once again. The stem cutter instrument removes a portion of the stem from the cranial clamp. The stem cutter instrument includes a capture mechanism which retains a sheared portion of the stem.
