Abstract

A surgical tool system including plural powered surgical handpieces. The handpieces are removably connected to a single control console. The control console has a power supply. A controller internal to the control console simultaneously supplies power to the plural handpieces. In the event the handpieces collectively draw more power than the power supply can provide, the control console temporarily stops the application of power to one of the handpieces.

Claims

1. A surgical handpiece control console, said control console including:

a plurality of connectors, each said connector configured to releaseably receive a separate surgical handpiece having an electrical power consuming unit so that plural surgical handpieces can be simultaneously connected to said control console;

a plurality of drivers, each said driver configured to, in response to an instruction signal specifically generated for that said driver, supply an energization signal to one of the surgical handpiece power consuming units through said connector that receives the handpiece, wherein said drivers are collectively configured to simultaneously supply energization signals to separate ones of the plural surgical handpiece power consuming units and the plurality of said drivers is less than the plurality of said connectors;

a switch assembly connected between said drivers and said connectors so that the energization signal output by any one of said drivers can be output through any one of said connectors to the handpiece connected to said connector; and

a control processor connected to said drivers and said switch assembly that;

receives command signals including command signals generated by plural input devices that are external from said control console;

evaluate the received command signals;

if the evaluation indicates that the received command signal is a command signal to actuate a first one of the surgical handpieces, generates an instruction signal to one of said drivers that causes the said driver to supply a specific energization signal for the first surgical handpiece power consuming unit based on the command signal and sets said switch assembly so that the energization signal output by the said driver is output through said connector to which the first handpiece is connected; and

, if the evaluation indicates that the received command signal is a command signal to actuate a second one of the surgical handpieces, generates an instruction signal to another one of said drivers that causes the other said driver to supply a specific energization signal for the second surgical handpiece power consuming unit based on the command signal and sets said switch assembly so that the energization signal output by the other said driver is output through said connector to which the second handpiece is connected wherein the energization signals from both said drivers are simultaneously output through said switch assembly.

2. The surgical handpiece control console of claim 1, further including:

a power supply for sourcing the power that forms the energization signals supplied by said drivers; and

a power supply monitor connected to said power supply for determining if the power sourced by said power supply exceeds a threshold level; and

wherein, said control processor is further configured to, when said power supply monitor determines the power sourced by said power supply exceeds the threshold level, generate instructions to limit the outputting of energization signals by one of said drivers.

3. The surgical handpiece control console of claim 1, wherein:

each said driver is custom configurable so that the said driver outputs an energization signal based on the received instruction signal and the custom configuration of said driver; and

said control processor is further configured to;

read data from memories associated with the surgical handpieces;

for a handpiece, based on the data read from the handpiece memory, custom configure the said driver that supplies energization signals to the handpiece.

4. The surgical handpiece control console of claim 1, wherein:

each said driver receives a feedback signal from the surgical handpiece to which said driver supplies energization signals;

filters the feedback signal to produce a filtered feedback signal; and

, based on the filtered feedback signal, selectively supplies energization signals to the surgical handpiece wherein, the filtering is performed by an adjustable filter; and

said control processor is further configured to;

read data from memories integral with the surgical handpieces; and

based on the data read from the surgical handpiece memory of the handpiece associated with a said driver, adjust the said filter of the said driver that supplies energization signals to the handpiece.

5. The surgical handpiece control console of claim 1, wherein:

each said driver supplies energization signals to the associated surgical handpiece based on a control algorithm, the control algorithm having variable coefficients; and

said control processor is further configured to;

read data from memories integral with the surgical handpieces; and

based on the data read from the surgical handpiece memory of the handpiece associated with a said driver, set the coefficients of the control algorithm of the said driver that supplies energization signals to the handpiece.

6. The surgical handpiece control console of claim 1, further including:

a display connected to said control processor;

a user interface associated with said display, said user interface configured to transmit control signals to said control processor;

wherein, said control processor is further configured to;

determine for a control signal received over said user interface, the handpiece for which the control signal is intended and the type of control signal;

present on the said display;

plural images on said display, including images identifying the types of the handpieces connected to said console and, based on control signals entered over said user interface, images indicating the type of control signal and the handpiece for which the control signal is entered; and

for the received control signal, configure the said driver that applies energization signals to the handpiece with which the control signal is associated so that the energization signals are supplied to the surgical handpieces based on the received control signal.
