Abstract

A power supply unit for a surgical instrument operated by an electric motor includes a battery-receiving housing separate and spaced apart from the surgical instrument. A fastening means or retainer fastens or retains the power supply unit to a body part of an operator. At least one power supply unit supplies power to at least one motor system. A control and monitoring device performs and/or monitors at least one function. A cable connection connects a cable for electrically coupling the power supply unit to a surgical instrument for operating the motor system thereof and/or for transmitting data and/or operating parameters.

First claim

The invention claimed is:

1. A power supply unit for an electromotively-operated surgical instrument, the power supply unit designed or provided as a separate component spaced from the surgical instrument and comprising:
a fastening means or retainer adapted for temporary fastening or retaining of the power supply unit to a body part of an operator of the surgical instrument;
at least one power storage unit designed for supplying power to at least one motor system of the surgical instrument, the at least one power storage unit accommodated in a receiving housing of the power supply unit;
a control and monitoring device within the receiving housing, the control and monitoring device configured to perform and/or monitor at least one of the following functions:
monitoring and/or displaying a state of charge of the at least one power storage unit,
switching on/off a power supply to the surgical instrument,
receiving and/or sending data to an external instrument actuation unit,
and
storing data and/or operating parameters; and

a cable and a cable connection for connecting the cable for electrically coupling the power supply unit to the surgical instrument for operating the at least one motor system and/or for transmitting data and/or operating parameters,
wherein the control and monitoring device is additionally configured to output and receive operating parameters and operating signals to and from the surgical instrument.

2. The power supply unit according to claim 1 , wherein the external instrument actuation unit is a manual control and/or a radio foot control and which communicates wirelessly with an application part.

3. The power supply unit according to claim 1 , wherein the power supply unit comprises a display that operates the power supply unit and displays information.

4. The power supply unit according to claim 3 , wherein the display indicates the state of charge of the at least one power storage unit and has buttons for switching the power supply on and off.

5. The power supply unit according to claim 1 , wherein the fastening means or retainer comprises a cuff.

6. The power supply unit according to claim 1 , wherein the receiving housing is fluid-tight.

7. The power supply unit according to claim 1 , wherein the cable is formed just long enough to connect the at least one motor system to the power supply unit at a wrist or forearm of the operator.

8. A surgical treatment system comprising:
the power supply unit according to claim 1 ; and
an electromotively-operated surgical instrument with a motor system,
the motor system configured for operation by a power storage unit and accommodated in a handpiece of the surgical instrument, the surgical instrument comprising a cable connection at a proximal end or end region of the handpiece, the cable connection configured for supplying power to the motor system and/or for transmitting data and/or operating parameters.

9. The surgical treatment system according to claim 8 , wherein the motor system is configured to be operated with direct current.

10. The power supply unit according to claim 1 , further comprising a battery or an accumulator, the battery or the accumulator being removable from the receiving housing so that the receiving housing is sterilizable without risk of damage to the at least one power storage unit and the control and monitoring device.

11. A power supply unit for an electromotively-operated surgical instrument, the power supply unit designed or provided as a separate component spaced from the surgical instrument and comprising:
a fastener or retainer adapted for temporary fastening or retaining of the power supply unit to a body part of an operator of the surgical instrument;
at least one power storage unit designed for supplying power to at least one motor system of the surgical instrument, the at least one power storage unit accommodated in a receiving housing of the power supply unit;
a control and monitoring device within the receiving housing, the control and monitoring device comprising at least one of:
a display or touchscreen for monitoring and/or displaying a state of charge of the at least one power storage unit,
a switch for switching on/off a power supply to the surgical instrument,
an interface for receiving and/or sending data to an external instrument actuation unit,
and
a storage medium for storing data and/or operating parameters; and

a cable and a cable connection for connecting the cable for electrically coupling the power supply unit to the surgical instrument for operating the at least one motor system and for transmitting data and/or operating parameters,
wherein the control and monitoring device additionally comprises a data transfer means for outputting and receiving operating parameters and operating signals to and from the surgical instrument.
