View Patent ↗A guarded surgical knife handle includes a handle portion with a blade holder, a chamber within the handle portion, and a slot. The guarded surgical knife handle also includes a guard having an open distal end slidably mounted within the handle portion that can slide longitudinally between an unguarded position and a guarded position. The guard is sized to surround the blade in the guarded position. The guarded surgical knife handle also includes a latch that latches the guard when the guard is slid into the guarded position and a first button that disengages the latch. The guarded surgical knife handle includes a bias member that forces the guard in a proximal direction to an unguarded position when the latch is disengaged along with a second button extending through the slot used to slide the guard in a distal direction into the guarded position.
