Abstract

By using a surgical microscope device, it becomes possible to continue surgery more reliably, even in the case in which the picture of the operating site is no longer displayed normally.
Provided is a surgical microscope device including: a microscope unit ( 110 ) that images an observation target, and outputs a picture signal; a support unit ( 120 ) that supports the microscope unit, and is configured as a balance arm; and an auxiliary observation device ( 30 ) that is attachable to the microscope unit or the support unit. A manually operated manual brake mechanism ( 40 ) is provided with respect to at least one of a plurality of rotation axis units constituting the support unit.

First claim

1 . A surgical microscope device, comprising:
a microscope unit that images an observation target, and outputs a picture signal; a support unit that supports the microscope unit, and is configured as a balance arm; and an auxiliary observation device that is attachable to the microscope unit or the support unit, wherein a manually operated manual brake mechanism is provided with respect to at least one of a plurality of rotation axis units constituting the support unit.

2 . The surgical microscope device according to claim 1 , wherein
the manual brake mechanism is provided with respect to a rotation axis unit having a smaller braking force in a case in which the manual brake mechanism is not provided, from among the plurality of rotation axis units constituting the support unit.

3 . The surgical microscope device according to claim 2 , wherein
the manual brake mechanism is provided with respect to a rotation axis unit in which a rotation moment that the rotation axis unit should support when maintaining an attitude of the support unit is greater than the braking force in the rotation axis unit in a case in which the manual brake mechanism is not provided.

4 . The surgical microscope device according to claim 3 , wherein
the manual brake mechanism is provided with respect to a rotation axis unit in which a stoppage of rotation is controlled by a driving of an actuator.

5 . The surgical microscope device according to claim 1 , wherein
the one manual brake mechanism is provided with respect to a plurality of the rotation axis units, and the one manual brake mechanism applies brakes to the plurality of the rotation axis units at a same time.

6 . The surgical microscope device according to claim 1 , wherein
the manual brake mechanism is provided with respect to one rotation axis unit, and applies a brake to the one rotation axis unit.

7 . The surgical microscope device according to claim 1 , wherein
the manual brake mechanism is made up of
a switch that is pressable in a certain direction, and
a friction brake that, by a movable part moving in the certain direction in conjunction with the switch and being pressed against a stationary part, produces a braking force due to friction at a contact surface between the movable part and the stationary part.

8 . The surgical microscope device according to claim 1 , wherein
the manual brake mechanism is made up of
a ring-shaped switch that is rotatable along an outer circumference of an arm unit constituting the support unit, and
a friction brake that, by a movable part moving in a certain direction in conjunction with the ring-shaped switch and being pressed against a stationary part, produces a braking force due to friction at a contact surface between the movable part and the stationary part.

9 . The surgical microscope device according to claim 1 , wherein
the auxiliary observation device is attached to the microscope unit or the support unit in a case in which a picture imaged by the microscope unit is not displayed normally on a display device, and the manual brake mechanism operates in a case in which the auxiliary observation device is attached to the microscope unit or the support unit.

10 . A surgical microscope system, comprising:
a microscope device that includes a microscope unit that images an observation target and outputs a picture signal, a support unit that supports the microscope unit and is configured as a balance arm, and an auxiliary observation device that is attachable to the microscope unit or the support unit; and a display device that displays a picture based on the picture signal, wherein in the microscope device, a manually operated manual brake mechanism is provided with respect to at least one of a plurality of rotation axis units constituting the support unit.
