Claims

[Claims for Utility Model Registration] (1) A casing disposed above the operating table, a lighting bulb provided in the casing, and a method for directing illumination from the lighting bulb to a predetermined location of a subject on the operating table. a light condensing means provided within the casing to focus light on a position; a driving means for tilting the casing so that the light convergence position on the subject is a desired position; and a practitioner. a beam irradiation means having a main body separate and independent from the casing so that it can be held and operated in the hand, and irradiating a wave beam to a desired position of the subject to form an irradiation area; an imaging means that is provided in the irradiation area and forms an image of the irradiation area by receiving the reflected beam from the irradiation area; a comparing means for generating an output including information on the direction of the difference when the two do not match; and a driving means for moving the light condensing position in the direction in which both of them match while the output from the comparing means is present. A medical shadowless illumination device comprising: a control means for controlling; (2) The apparatus according to claim 1, wherein the driving means includes a first motor that tilts the casing along a first plane perpendicular to the top surface of the operating table; a second motor for tilting the housing along a second plane perpendicular to both of the planes, the comparison means having a first output indicating a discrepancy with respect to the first plane direction; , a second output indicating a discrepancy regarding the second plane direction, and a control means controls the first motor based on the first output, and a control means controls the first motor based on the first output; A medical shadowless illumination device, characterized in that the second motor is controlled based on the output. (3) The device according to claim 2, wherein the drive means moves the housing in the vertical direction.
The beam irradiation means has a function of applying a predetermined modulation to the wave beam to provide information regarding the vertical position of the casing, and the third A medical shadowless illumination device characterized by controlling a motor.
