摘要:
A stereomicroscope includes an objective optical system, a variable magnification optical system, and a plurality of imaging optical systems, in which the plurality of imaging optical systems can be moved in a plane perpendicular to the optical axis of the variable magnification optical system. Thus, the stereomicroscope has the advantage that where one of two observers wishes to observe a brighter image, the amount of light can be adjusted, without replacement of a light source, by moving the imaging optical systems.

A stereomicroscope is equipped with an objective lens, a variable magnification optical system having an optical axis common with that of the objective lens, a splitting optical system splitting emergent light from the variable magnification optical system into a plurality of optical paths, and an eyepiece disposed in at least one of the optical paths, having a diameter larger than the interpupil distance of an observer. Thus, the stereomicroscope has advantages that, with a simple structure and easy adjustment, many people can make observations, the mountings of photographic and TV devices are possible, the directions in which plural observers see through the microscope can be changed, and eyestrain is difficult to occur which may be caused by the difference in magnification between the images of a bilateral observation optical system.

The operating microscope comprises at least one suction port formed in a microscope body or an arm for supporting the microscope body which is to be enveloped in a drape, and an exhaust fan or exhaust pump connected to the suction port. An exhaust port to be connected to an exhaust pump may be formed in the drape. Since air is exhausted out of the drape, and the drape is brought into close contact with the microscope body and the arm by operating the exhaust fan or the exhaust pump, the drape does not constitute a hindrance in the visual field of a surgeon or dgrade operability of the microscope.

The surgical microscope comprises a stand, an arm movably attached to said stand for sustaining a microscope body, an electric control equipment divided into a plural number of units removably piled up on said stand and a foot switch unit to be used for executing various types of functions. Accommodated in each unit are a function control means having a single specific function or plural specific functions different from those of the other units and an independent power source means connected to said function control means in a relation of 1:1 or in a different combination. The surgical microscope can be designed compact as a whole, has high operability and assures high security during operation. Should a function be lost due to troubles during operation, the surgical microscope prevents the other functions from being influenced by the troubles and allows to speedily restore the lost function.

To provide a surgical microscope comprising a microscope collimator for enabling the operator to easily recognize the swivel center of the microscope body regardless of what position the microscope body moves for easy setting of the swivel center point of the microscope body, a surgical microscope pivotally supporting a microscope body having, an observation optical system with one point on an observation optical axis of the microscope body as the swivel center. The surgical microscope comprises index projectors as swivel center visible indicators being capable of recognizing the swivel center. This configuration enables the operator to easily recognize the swivel center of the microscope body for easy setting of the swivel center point of the microscope body. Also, to provide a surgical microscope which does not disturb an operator who handles the microscope or performs an operation and also enables the operator to easily observe at every angle from every direction for improving operability, the surgical microscope is capable of changing an observation angle and an observation direction with a gaze point P on an observation optical axis a of a microscope body having an observation optical system as a rotation center. A base unit that can be moved in X, Y, and Z directions is disposed at a position relative to the microscope body and a swivel base rotatable with the gaze point P as a rotation center is installed above the base unit.

An image observation apparatus comprising an image display unit for displaying an observation image and a supporting mechanism for supporting the image display unit movably and adjustably in the directions of three, substantially perpendicular axes. Since the supporting mechanism of this image observation apparatus can move and adjust the image display unit in three orthogonal axial directions, an operator need not select a plurality of articulates for operating them when he/she wants to move the image display unit to a desired axial direction. Further, one of the three axes can be a rotational axis for turnably supporting the image display unit around the operator. According to this configuration, the image display unit can be independently moved and adjusted in three axial directions, while the observation angle of the observer with respect to the display face of the image display unit is kept constant.
摘要:
Binocular luminous fluxes are formed by an objective lens and a pair of relay lenses and go through a splitting optical system, which allows an assistant to observe the same stereoscopic view as the surgeon by using an assistant's binocular eyepiece optical system at a location across from the surgeon via a splitting optical system. Part of at least one of the binocular luminous fluxes is incident on a pupil splitting optical system, forming a binocular luminous flux that has undergone pupil splitting, which allows stereoscopic observation by pupil splitting even when the assistant's binocular eyepiece optical system is rotated to the surgeon's side.
