Abstract
A surgical tool system is provided. The surgical tool system includes a tool unit including an energy applicator that is actuated by a power generating unit. The surgical tool system also includes a battery and control module including a module housing shaped to receive the tool unit and having 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.
Claims20
A surgical tool system, the system comprising:
- a tool unit including:
- a brushless motor;
- and
- at least one tool contact that is connected to the brushless motor over which energization currents are applied to the brushless motor to cause actuation of the brushless motor;
- and
- a battery and control module configured to be connected to a battery charger or the tool unit, the battery and control module including:
- a user-actuated switch, the user actuated switch including a lever including a finger pad configured to receive a finger of a user;
- a switch sensor configured to monitor a state of the user-actuated switch and to output a sensor signal based on a state of the switch;
- at least one rechargeable cell;
- at least one module contact, the at least one module contact positioned to connect to the battery charger when the battery and control module is connected to the battery charger, and the at least one module contact positioned to connect to the at least one tool contact when the tool unit is connected to the battery and control module;
- a controller being configured to receive an amount of power from the at least one rechargeable cell and regulate outputting of the energization currents from the at least one rechargeable cell based on the sensor signal and based on an operating state of the brushless motor;
- and
- a wake-up circuit connected to the at least one module contact and the controller, wherein the wake-up circuit is configured to:
- determine that the battery and control module is connected to the battery charger, wherein the at least one rechargeable cell is configured to provide an increased amount of power to the controller in response to the wake-up circuit determining that the battery and control module is connected to the battery charger;
- and
- determine that the battery and control module is connected to the tool unit, wherein the at least one rechargeable cell is configured to provide an increased amount of power to the controller in response to the wake-up circuit determining that the battery and control module is connected to the tool unit.

A surgical tool system comprising:
- a tool unit including:
- a tool housing;
- a brushless motor configured to emit a signal representative of an operating state of the brushless motor;
- and
- at least one tool contact, the at least one tool contact being connected to the brushless motor, and wherein energization currents are applied to the brushless motor via the at least one tool contact to cause actuation of the brushless motor,
- wherein the at least one tool contact is mounted to the tool housing and the tool housing is formed from material through which the signal emitted by the brushless motor can pass therethrough;
- and
- a battery and control module configured to be connected to the tool unit, the battery and control module including:
- at least one rechargeable cell;
- at least one module contact, the at least one module contact positioned to connect to the at least one tool contact when the tool unit is connected to the battery and control module;
- a controller being configured to receive an amount of power from the at least one rechargeable cell and regulate outputting of the energization currents from the at least one rechargeable cell based on the operating state of the brushless motor;
- and
- a wake-up circuit connected to the at least one module contact and the controller, wherein the wake-up circuit is configured to determine that the battery and control module is connected to the tool unit, wherein the at least one rechargeable cell is configured to provide an increased amount of power to the controller in response to the wake-up circuit determining that the battery and control module is connected to the tool unit.
