There is provided a medical observation device, including: an observation unit configured to perform magnified observation of a surgical site; a vibration sensor that detects a vibration of the observation unit; a support unit that supports the observation unit; and a control unit that conducts an image shake correction that corrects a shake in an image observed by the observation unit, based on a detection value from the vibration sensor.

Positioning assemblies for use with a robot include a gimbal assembly having a gimbal's rotational center is positioned directly above a center of gravity of a payload. One or more linear counter masses and/or one or more rotating masses (flywheels) can be provided, and each can include an actuator or brake to control forces acting between the counter masses and/or flywheels and the payload and stabilize the payload during and after movement of the payload with the robot.

A memory device includes a first and second conductor respectively included in a first and second layer stack stacked in a first direction and separated from each other; a first and second portion of a semiconductor extending in the first direction between the first and the second layer stack, and separated from each other in same layer; a first film between the first conductor and the first portion; a second film between the second conductor and the second portion; a first insulator between the first conductor and the first film; a second insulator between the second conductor and the second film; a third insulator between the first insulator and the first film; and a fourth insulator between the second insulator and the second film. The third and fourth insulator have a higher dielectric constant than the first and second insulator.

The invention relates to a microscope (1), in particular an ophthalmic surgical microscope having a vitreoretinal viewing system (6), an optics carrier (14) and a support (2). The invention also relates to a method and a motion controller controlling the movement of the vitreoretinal viewing system (6). The optics carrier (14) is attached movably to the support (2). The vitreoretinal viewing system (6) in turn is attached movably to the optics carrier (14). The vitreoretinal viewing system (6) comprises a front piece (30), such as a optics carrier (14). To avoid contact of the front piece (30) with an eye (16) while the optics carrier (14) is moved for focusing a microscope lens (18), the position of the front piece (30) is automatically maintained stationary with respect to the support (2). This is obtained by controlling the vitreoretinal viewing system (6) to perform a counter movement to the movement of the optics carrier (14).

In a medical system (1), speckle contrast calculation means (1313, 1314) calculates a first speckle contrast value for each pixel based on a first speckle image at a first exposure time and/or a second speckle contrast value for each pixel based on a second speckle image at a second exposure time shorter than the first exposure time. In addition, speckle image generation means (1315) generates a speckle contrast image on the basis of the first speckle contrast value and/or the second speckle contrast value depending on a detection result of motion of an image capturing target by motion detection means (1312).

The present disclosure provides a system for active vibration reduction of a surgical microscope. The system includes a surgical microscope with an optical head connected to a control device that adjusts the position of the optical head in any of the X, Y, and Z-directions. The system also includes a processor and an accelerometer that detects motion of the optical head and generates data relating to the motion. The disclosure also provides a method for active vibration reduction, which includes receiving data relating to motion of an optical head of a surgical microscope, determining whether the motion is a vibration event or an intentional movement, determining a distance and direction the optical head must be adjusted to reduce the vibration caused by the motion detected, and generating and transmitting a control signal to adjust the position of the optical head to reduce the vibration of the vibration event.

A module (104) for a microscope stand (100) comprises a control device (118) with at least one computer hardware component (120, 122) being configured to control the microscope stand (100). The module (104) further comprises a locating device (164) configured to interact with another locating device (162) formed in a housing (102) of the microscope stand (100) for mounting the module (104) at a predetermined installation site within the housing (102).

To simplify the optical calibration of an optical observation apparatus, a stand for an optical observation unit including a calibration object arranged directly on the stand in a fixed location is specified. Moreover, an optical observation apparatus, which includes such a stand and an optical observation unit connected to the stand, a method for calibrating such an optical observation apparatus, and a computer program are specified.

A surgical electronic microscope device (10) includes a microscope unit (110) and a support unit (120) that supports the microscope unit (110). The microscope unit (110) images an operative site of a patient (330) on an operating table (340), and outputs an image signal. The support unit (120) includes a prop unit (290c). The prop unit (290c) supports a second arm (290b) rotatably around an axis (05). The second arm (290b) supports a first arm (290a) rotatably around an axis (04). The first arm (290a) supports the microscope unit (110). Pivoting the second arm (290b) on the axis (05) while keeping the first arm (290a) substantially level makes it possible to change a height of the microscope unit (110). A length (V) of the second arm (290b) is greater than a length (H) of the first arm (290a). Accordingly, a movable range of the microscope unit (110) in a vertical direction is wide. Both an operation performed by a surgeon at a standing position and an operation performed by a surgeon at a seated position can be therefore covered.

To enable observation of the operating site to be continued more easily 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 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 is configured to enable observation of an observation range provided by the microscope unit.
