First Claim
Patent Images
1. A handpiece with a built-in camera comprising:
- a handpiece body which includes a cutting tool attached to a head portion thereof, and a light receiving port provided at a position near the cutting tool;
a grip portion which is detachably connected to the handpiece body; and
a color camera module which is stored inside the handpiece body,wherein the color camera module comprises a camera unit having a condensing lens unit and a color image sensor that outputs a color image signal, and an arbitrary number of light-emitting elements which are circularly arranged around a periphery of the camera unit;
and the handpiece with built-in camera further comprising;
an objective lens which faces the light receiving port provided in the head portion, and an optical transmission body which is disposed in the handpiece body with an incidence end of the optical transmission body facing the objective lens and an exit end of the optical transmission body facing the condensing lens unit, anda photographing optical system which transmits imaging light of an affected area to the camera unit via the objective lens and the optical transmission body.
