Battery-powered hand-held ultrasonic surgical cautery cutting device

A battery-powered, modular surgical device, comprising:

• an electrically powered surgical instrument interfacing with bodily tissue during surgery and requiring a pre-determined minimum amount of electrical energy to power the surgical instrument completely through a surgical procedure;
• and
• a power module assembly having:
• at least one modular battery supplying power for the surgical instrument during use and having a current state of electrical charge;
• and
• a control circuit electrically coupled to the at least one modular battery and to the surgical instrument and comprising a memory and at least one microprocessor:
• the memory storing data regarding the pre-determined minimum amount of electrical energy;
• and
• the microprocessor being programmed:
• to monitor and determine the current state of electrical charge of the at least one modular battery;
• prior to beginning an anticipated surgical procedure, to compare the current state of electrical charge of the at least one modular battery to the pre-determined minimum amount of electrical energy;
• and
• to permit the battery to discharge if the current state of electrical charge of the battery is above the pre-determined minimum amount of electrical energy;
• and
• to maintain the battery in a non-discharge state if the current state of electrical charge of the battery is below the pre-determined minimum amount of electrical energy.
