Abstract
Abstract A handpiece for holding dental tools which contains an illuminating system is disclosed. The illuminating system consists of a fiber optic bundle which passes through the handpiece. The fiber optic bundle is connected to a remote light source on one end, with the other end illuminating the region in which the dental tool is to be operated.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
For use in conjunction with a dental console adapted to supply fluid to a remote handpiece, in combination: a handpiece having one end adapted to connect to a tool; work area illuminating means including a fiber optic bundle integrally contained within said handpiece, said fiber optic bundle having a proximal end adapted to connect to a remote external light source at the console and a distal end, said distal end of the fiber optic bundle being split into a plurality of sections, said first section of the distal end of the fiber optic bundle being canted relative to a second section of the distal end of the fiber optic bundle whereby the area of operation of the tool is illuminated from different angles, by light being conducted from said proximal end of said fiber optic bundle through each section of said distal end.
Claim 2
Dependent Claim
143 words
For use in conjunction with a dental console adapted to supply fluid to a remote handpiece, in combination: a handpiece having one end adapted to connect to a tool; work area illuminating means including a fiber optic bundle integrally contained within said handpiece, said fiber optic bundle having a proximal end adapted to connect to a remote external light source at the console and a distal end, said distal end of the fiber optic bundle being split into a plurality of sections, said first section of the distal end of the fiber optic bundle being canted relative to a second section of the distal end of the fiber optic bundle whereby the area of operation of the tool is illuminated from different angles, by light being conducted from said proximal end of said fiber optic bundle through each section of said distal end.
Claim 3
Dependent Claim
174 words
For use in conjunction with a dental console adapted to supply fluid to a remote handpiece, in combination: a handpiece having one end adapted to connect to a tool; work area illuminating means including a fiber optic bundle integrally contained within said handpiece, said fiber optic bundle having a proximal end adapted to connect to a remote external light source at the console and a distal end, said distal end of the fiber optic bundle being split into a plurality of sections including a first and a second section of said distal end, said first and second sections of the fiber optic bundle being formed such that the diffusion of light conducted through said first section of said distal end of said fiber optic bundle is greater than the diffusion of light conducted through said second section of said distal end of said fiber optic bundle, such that light conducted from said proximal end of said fiber optic bundle through each section of said distal end illuminates the area of operation of the tool.
