Abstract

A medical imaging device according to the present invention includes an illumination unit that spot-illuminates a center of operative field of a surgical patient, an operative field camera unit that images a center of irradiation range by the illumination unit, a housing that covers the illumination unit and the operative field camera unit, and a pair of display units and that are visible from both sides of the surgical patient.

Claims (40)

1 . A medical imaging device comprising:

an illumination unit configured to spot-illuminate a center of operative field of a surgical patient;

an operative field camera unit configured to capture an image of a center of irradiation range by the illumination unit;

a housing that covers the illumination unit and the operative field camera unit; and

a pair of display units attached to side surfaces of the housing and visually recognizable from both sides of the surgical patient.

2 . The medical illumination imaging device according to claim 1 , wherein

the illumination unit includes a plurality of light sources, the plurality of light sources is arranged on a diagonal line or in a ring shape so as to surround a periphery of the operative field camera unit with the operative field camera unit as a center, and the illumination unit is provided at an angle at which an illumination optical axis of the illumination unit and an image axis of the operative field camera unit coincides with each other on the center of operative field.

3 . The medical illumination imaging device according to claim 1 , further comprising:

a reflection unit that reflects irradiation light emitted from the illumination unit to coincide with an image axis of the operative field camera unit.

4 . The medical illumination imaging device according to claim 1 , wherein

the illumination unit and the operative field camera unit are arranged in parallel, and

the illumination unit is installed at an angle at which an illumination optical axis of the illumination unit coincides with an image axis of the operative field camera unit arranged on the center of operative field.

5 . The medical illumination imaging device according to claim 1 further comprising:

an adjusting unit configured to adjust a direction of an image displayed on the display units.

6 . The medical imaging device according to claim 1 , further comprising

an inclination adjusting unit configured to adjust an angle formed by an illumination optical axis of the illumination unit and an image axis of the operative field camera unit, wherein

the inclination adjusting unit adjusts the angle formed.

7 . The medical imaging device according to claim 1 , wherein

the illumination unit spot-illuminates the center of operative field of the surgical patient from a position of 10 cm to 150 cm away from the operative field.

8 . The medical illumination imaging device according to claim 2 , further comprising:

an adjusting unit configured to adjust a direction of an image displayed on the display units.

9 . The medical illumination imaging device according to claim 3 , further comprising:

an adjusting unit configured to adjust a direction of an image displayed on the display units.

10 . The medical illumination imaging device according to claim 4 , further comprising:

an adjusting unit configured to adjust a direction of an image displayed on the display units.

11 . The medical imaging device according to claim 2 , further comprising

an inclination adjusting unit configured to adjust an angle formed by an illumination optical axis of the illumination unit and an image axis of the operative field camera unit, wherein

the inclination adjusting unit adjusts the angle formed.

12 . The medical imaging device according to claim 3 , further comprising

an inclination adjusting unit configured to adjust an angle formed by an illumination optical axis of the illumination unit and an image axis of the operative field camera unit, wherein

the inclination adjusting unit adjusts the angle formed.

13 . The medical imaging device according to claim 4 , further comprising

an inclination adjusting unit configured to adjust an angle formed by an illumination optical axis of the illumination unit and an image axis of the operative field camera unit, wherein

the inclination adjusting unit adjusts the angle formed.

14 . The medical imaging device according to claim 2 , wherein

the illumination unit spot-illuminates the center of operative field of the surgical patient from a position of 10 cm to 150 cm away from the operative field.

15 . The medical imaging device according to claim 3 , wherein

the illumination unit spot-illuminates the center of operative field of the surgical patient from a position of 10 cm to 150 cm away from the operative field.

16 . The medical imaging device according to claim 4 , wherein

the illumination unit spot-illuminates the center of operative field of the surgical patient from a position of 10 cm to 150 cm away from the operative field.
