8 . The surgical tool system of claim 6 , wherein the tool unit is releasably seated in the bore of the nacelle when the tool unit is received by the module housing.
9 . The surgical tool system of claim 1 , wherein the channel is isolated from the void space.
10 . The surgical tool system of claim 1 , wherein the battery and control module further comprises a latch feature integral with the module housing that cooperates with the tool unit to releasably hold the module housing to the tool unit.
11 . The surgical tool system of claim 1 , wherein the energy applicator is elected from a group comprising: a saw blade, a drill bit, a reamer, a wire, and a bur.
12 . The surgical tool system of claim 1 , wherein the module housing is pistol shaped.
13 . A battery and control module for providing power and control for use with a tool unit that includes a tool housing having at least one contact mounted thereto, a power generating unit including a cannulated rotor, the power generating unit being electrically connected to the at least one contact, the tool unit further including an energy applicator that is actuated by the power generating unit that is adapted for use to perform a medical procedure, the battery and control module comprising:
a module housing shaped to receive the tool unit and is further formed to have a bore that establishes a channel through the module housing, wherein:
when the tool unit is received by the module housing, the channel extends to the cannulated rotor; and
the module housing includes a void space and is constructed so as to seal the void space from an ambient environment;
at least one rechargeable cell disposed in the void space;
at least one contact, mounted to the module housing, and positioned to engage with the at least one contact of the tool unit housing; and
a tool unit controller disposed in the void space that selectively connects the at least one cell to the at least one contact mounted to the module housing so as to regulate output of energization signals from the at least one cell through the at least one contact to the power generating unit.
14 . The battery and control module of claim 13 , wherein the module housing is formed of a proximal shell and a distal shell, the proximal shell and the distal shell being configured to mate to form the module housing.
15 . The battery and control module of claim 14 , wherein the proximal shell includes an end plate, wherein the end plate is formed with the bore, wherein the bore is configured to receive a wire to be fed into the cannulated rotor of the tool unit.
16 . The battery and control module of claim 15 , wherein battery and control module further comprises a nacelle integrally formed with the distal shell, wherein the nacelle includes an end plate having a boss, the boss being formed with a bore that extends axially through the boss and through the end plate.
