• the supply hose carrying air, water, and light from said control unit to said supply hose connector;
• the connector including a connector body and a nose extending from said connector body;
• said connector body including an air passage operably connectable to the source of air, a water passage operably connectable to the source of water, and a light tube passage in light transmitting relationship with the source of light;
• said nose having a generally smooth uninterrupted surface with an air exit in fluid communication with said body air passage, a water exit in fluid communication with said water passage, and a central passage therethrough in communication with said light tube passage;
• and
• a light tube extending through said connector body light tube passage and said nose central passage.

A swivel connector for connecting an instrument to a supply of air, water, and light;

• the swivel connector including a first portion which is rotatably received in a second portion, said second portion being located in a body of said tool;
• said connector second portion including a central passage therethrough, a first annular channel formed in said central passage;
• a first axial passage in fluid communication with said first annular channel and extending to a forward surface of said connector second portion, a second annular channel formed in said central passage, and a second axial passage in fluid communication with said second annular channel and extending to a forward surface of said connector second portion;
• said central passage having a central outlet sized to admit a light tube to pass therethrough;
• said connector first portion including a connector body and a nose extending from said connector body;
• said connector body including an air passage operably connectable to a source of air, a water passage operably connectable to a source of water, and a light tube passage adapted to receive the light tube and to place the light tube in light transmitting relationship with a source of light;
• said nose being sized to pass through said connector second portion central passage and having a generally smooth uninterrupted surface with an air exit in fluid communication with said body air passage, a water exit in fluid communication with said water passage, and a central passage therethrough in communication with said light tube passage;
• said air and water exits being in fluid communication with said first and second annular passages in said connector second portion when said connector first portion is received in said connector second portion;
• and
• said light tube extending through said connector body light tube passage, said nose central passage, and said connector second portion central passage exit.
