Abstract:
[Problem] To provide a handpiece with built-in camera, which allows treatment to be performed while viewing a clear color image of a treatment site that would normally be difficult to see, such as the distal wall of a tooth. [Solution] The present invention is a handpiece (1) with built-in camera comprising: a handpiece body (2) to which a cutting tool (16) is fitted to the head part (14) thereof, and provided with with a light intake port (13) in a position near the cutting tool (16); a grip part (3) which is detachably connected to this handpiece body (2); and a camera module (21) stored in the inside of the handpiece body (2).
The color camera module (21) is equipped with a camera unit (31) having a condensing lens unit (33) and a color image sensor (38) that outputs a color image signal, and an arbitrarily-defined number of light-emitting elements (LEDs)(24) positioned in a circular manner around the periphery of this camera unit (31). The handpiece is equipped with an object lens (32) near the light intake port provided at the head part (14), and a rod fiber (43) positioned within the handpiece body (2) in such a manner that the incident end of the rod fiber is close to the object lens (32), and the exit end of the rod fiber is close to the condensing lens unit (33).
