Single instrument electrosurgery apparatus and its method of use

A surgical method comprising:

• providing a first surgical instrument including a body extending along a longitudinal axis between opposite proximal and distal end surfaces, the distal end surface comprising a first cavity and a second cavity, the first cavity comprising a first light bulb disposed therein, the second cavity comprising a second light bulb disposed therein, the primary assembly comprising a shaft, the shaft comprising opposite proximal and distal ends, the proximal end being coupled to the body, the primary assembly comprising a blade coupled to the distal end, wherein the first light bulb is an ultraviolet (UV) light bulb and the second light bulb is configured to emit visible light;
• sterilizing tissue using the first light bulb;
• illuminating the sterilized tissue using the second light bulb;
• and
• cutting the sterilized and illuminated tissue with the blade.

A surgical instrument comprising:

• a body extending along a longitudinal axis between opposite proximal and distal end surfaces, the distal end surface comprising a plurality of spaced apart first cavities and a plurality of spaced apart second cavities, the first and second cavities each being disposed radially about the longitudinal axis such that each of the first cavities is positioned between two of the second cavities and each of the second cavities is positioned between two of the first cavities, the first cavities each comprising a first light bulb disposed therein, the second cavities each comprising a second light bulb disposed therein;
• a shaft comprising opposite proximal and distal ends, the proximal end being coupled to the body;
• an electrode coupled to the distal end;
• and
• an insulating portion positioned between the shaft and the electrode.
• wherein the first light bulbs are ultraviolet light bulbs and the second light bulbs are light emitting diodes.
