A light source device includes a first light source, a second light source, and a light source control unit. The first light source emits laser light. The second light source emits light. The light source control unit controls the operations of the first and second light sources. The light source control unit executes each of first switching control and second switching control on laser light which is applied to a subject after emitted from the first light source based on a time reference in accordance with a class specified by a laser standard indicating a safety standard for laser products. In the first switching control, a lighting state is switched from the first light source to the second light source. In the second switching control, the lighting state is switched from the second light source to the first light source.

Light source device and subject observation system

A medical control apparatus includes a circuitry configured to: generate an irradiation image represented by illuminating-light irradiation, based on a brightness distribution of a captured image captured by an imaging device; and control generation of a projection image and projection of the projection image onto a subject by an image projector provided in an optical member based on the irradiation image and a rotation angle for rotation of the optical member rotatably coupled to the imaging device about a longitudinal axis of the optical member relative to the imaging device.

Medical control apparatus and medical observation system

A receptacle module for detachably connecting a connector of a distal end device coming into contact with or inserted into a subject includes: a receptacle substrate including a first surface on which a receptacle to which the connector is detachably connected is mounted, and a second surface on an opposite side of the first surface; a patient circuit unit conducted to the distal end device via the receptacle; and a conductive shielding member mounted on the second surface and configured to shield the patient circuit unit from the opposite side.

Receptacle module and medical device

A medical light source device includes: a first solid state light emitting element configured to emit first color light; a second solid state light emitting element configured to emit second color light; a third solid state light emitting element configured to emit third color light; a fourth solid state light emitting element configured to emit fourth color light; and a color synthesis optical device configured to synthesize the first color light, the second color light, the third color light, and the fourth color light. The color synthesis optical device includes a first color separation surface, a second color separation surface disposed to intersect with the first color separation surface, and a third color separation surface disposed on a light path latter stage with respect to the first color separation surface and the second color separation surface.
