  • Medical observation device and lens barrel of medical observation device
    Patent number: 10274693
    Abstract: To realize weight reduction and ensure favorable performance of an imaging element. A lens barrel of a medical observation device includes: a barrel unit including an imaging optical system configured to acquire an image of an object, and a housing in which the imaging optical system is disposed; and an element unit including an imaging element configured to photoelectrically convert the image of the object acquired by the imaging optical system, and an element holder configured to hold the imaging element, in which the housing is made of a resin material, and the element holder is made of a material different from that of the housing. With this configuration, the housing in which the imaging optical system is disposed is made of the resin material, and the element holder configured to hold the imaging element is made of the material different from that of the housing. Thus, weight reduction can be realized while favorable performance of the imaging element can be ensured.
