Abstract
An electrical coupling unit for electrically connecting an outlet of non-sterile electrosurgical apparatus to a sterile electrosurgical handpiece. The coupling unit is sterile, and can be provided at a location convenient to the surgeon. The coupling unit is also provided with plural outputs for connecting by one or more suitable cables to handpieces held by the surgeon. The latter cables are preferably also maintained in a sterile condition. The coupling unit is provided with a selector switch which functions to selectively connect an output of the electrosurgical apparatus to an output on the coupling unit. The coupling unit outputs are color-coded for ease of selection, each different color representing a different electrosurgical current or instrument. Preferably, the switch knob is also color-coded so that a position representing a particular electrosurgical current or instrument can easily and quickly be achieved. Where multiple cables connected to multiple handpieces are used, it is preferred for the cables also to be color-coded to match the color-coding on the switch.
