Orthopedic surgical device having a rotatable portion and lock

A module for a surgical driver with at least one drive shaft, said surgical driver comprising a handle portion and a barrel portion, the module comprising:

• releasable attachment means for releasably attaching the module to the surgical driver so that the module forms a portion of the barrel portion of the surgical driver,
• tool mounting means for releasably receiving an orthopedic surgical tool;
• means for engaging the at least one drive shaft,
• rotational orientation means for orienting the tool mounting means in a plurality of angular positions about an axis of the barrel portion of the surgical driver so that the orthopedic surgical tool is capable of being mounted in a plurality of angular positions relative to the barrel portion of the surgical driver,
• releasable locking means for releasably locking the rotational orientation means in one of a plurality of discrete angular positions about the axis of the barrel portion of the surgical driver, said releasable locking means having a locking member movable between a lock position and a release position spaced from the lock position,
• a stationary portion adapted to be fixed relative to the barrel portion of the surgical driver when the releasable attachment means attaches the module to the surgical driver, and a movable portion comprising a substantially cylindrical sleeve having a plurality of slots spaced about its periphery, each of said slots having a longitudinal axis and a pair of tapered walls, said movable portion being adapted to rotate about an axis of the sleeve,
• the locking member comprising a detent with tapered walls that are sized and shaped to be received in one of the slots of said cylindrical sleeve when said locking member is in said lock position;
• and
• spring biasing means for biasing said locking member toward said lock position.

A non-modular orthopedic saw comprising:

• a barrel portion having an axis,
• a handle portion situated at an angle relative to said barrel portion,
• blade mounting means for releasably receiving an orthopedic saw blade, said blade mounting means being situated on said barrel portion,
• rotational orientation means for orienting the blade mounting means in a plurality of angular positions about the axis of the barrel portion of the saw so that the orthopedic saw blade is capable of being mounted in a plurality of angular positions relative to the barrel portion of the saw,
• releasable locking means for releasably locking the rotational orientation means in one of a plurality of angular positions about the axis of the barrel portion of the saw, said releasable locking means having a locking member movable between a lock position and a release position spaced from the lock position,
• a stationary portion adapted to be fixed relative to the barrel portion of the saw, and a movable portion comprising a substantially cylindrical sleeve having a plurality of slots spaced about its periphery, each of said slots having a longitudinal axis and a pair of tapered walls, said movable portion being adapted to rotate about an axis of the sleeve,
• the locking member comprising a detent with tapered walls that are sized and shaped to be received in one of the slots of said cylindrical sleeve when said locking member is in said lock position;
• and
• spring biasing means for biasing said locking member toward said lock position.
