- the stand can be designed in such a way that it enables movement of the microscope head in space, in particular with at least one, preferably with six, degrees of freedom, where a degree of freedom can be a translational or a rotational degree of freedom.
- a translational and a rotational movement as well as the corresponding degrees of freedom can relate to a reference coordinate system.
- a vertical axis (z-axis) of this reference coordinate system can be oriented parallel to the gravitational force and the corresponding vertical direction (axial direction) can be oriented opposite to the gravitational force.
- the vertical axis can be parallel to an optical axis of the surgical microscope, which can in particular be an optical axis of the objective, and the corresponding vertical direction can be oriented away from the surgical microscope towards an object space.
- a longitudinal axis (x-axis) and a transverse axis (y-axis) of the reference coordinate system can span a plane that is oriented perpendicular to the vertical axis.
- the longitudinal and transverse axes can also be oriented orthogonally to each other.
- the longitudinal and transverse directions (axial directions) can be oriented in such a way that the axes form a Cartesian coordinate system.
- the surgical microscope in particular the stand, comprises at least one drive device for moving the surgical microscope, in particular the microscope head.
- a drive device can be a servo motor, for example.
- the stand can also comprise means for transmitting force/torque, e.g. gear units.
- the surgical microscope can also comprise means for controlling the movement.
- a user can, for example, control the at least one drive device in such a way that the surgical microscope carries out a desired movement in space. This allows the surgical microscope to be positioned in space, for example, in a predetermined target position, where the position designates a position and/or orientation of the microscope head.
- a movement can also be controlled with a desired movement method, e.g. a desired direction of movement.
- the control means can be designed for haptic confirmation by a user/surgeon. However, this is not mandatory. Alternatively, the means can enable voice control, for example.
- the surgical microscope further comprises at least one control element.
- the control element is a means of controlling the movement.
- the control element can be designed in particular for manual operation by a user, i.e. for haptic operation. Operation can be carried out, for example, by pressing, moving or turning.
- the control element can be designed as a joystick or as a switch, in particular as a toggle or rocker switch.
- a main operating mode the movement of the microscope head is controlled in a first predetermined movement mode by actuating an operating element in a first actuation mode.
- the main operating mode can be activated, for example, by actuating a corresponding activation means, which is also referred to below as a further activation means. This is explained in more detail below.
- the actuation mode refers to the manner in which the operating element is actuated.
- the operating element can be designed in such a way that it can be actuated in different actuation modes. Actuation in different actuation modes can take place, for example, if different sections of the operating element are actuated and/or the corresponding actuation force has different directions and/or different amplitudes.
- a movement of the microscope head in a first predetermined direction can be controlled.
- the movement of the microscope head can also be controlled in a further direction, which can be opposite to the first direction, for example.
- different modes of operation can differ in at least one property of the operation, where the property is, for example, a location of the operation, a direction of the operation, an intensity of the operation.
- the control element can be arranged in particular on the microscope head, further in particular on a handle of the surgical microscope.
- the handle can also be arranged on the microscope head or its housing. Alternatively, a control element can of course also be arranged on the housing of the microscope head or elsewhere.
- a method of movement can define at least one property of a movement.
- a method of movement can define a direction of movement and a type of movement.
- a type of movement can be a translational movement, a rotational movement or a mixture of these.
- a method of movement can also define a type and/or a number of Degrees of freedom of movement, in particular the released degrees of freedom of movement, can be specified.
- a manner of movement can also specify a reference point and/or a reference axis of the movement, in which case the movement in this manner of movement can be a rotational movement around the reference point and/or the reference axis and/or a translational movement along the reference axis.
- an auxiliary operating mode can be activated, in particular by generating an activation signal via a corresponding activation means.
- This activation means can also be referred to as the first activation means.
- the first activation means can also be referred to as the first activation means.
- a movement of the microscope head in a further predetermined movement mode is controlled in the auxiliary operating mode by actuating the operating element in the first actuation mode, wherein the first and the further movement modes are different from one another.
- the first and the further movement modes differ in at least one property.
- a translational movement can be controlled when the operating element is actuated in the first actuation mode in the main operating mode, while in the auxiliary operating mode a rotational movement is controlled by the same actuation.
- the method according to the invention makes it possible to control different movements by operating the same control element in the same way.
- This increases the scope of (control) functions that can be controlled with the control element.
- different control elements and/or different ways of operating a single control element do not have to be provided to control different movements, which simplifies operation for controlling movements, in particular because a user does not have to operate different control elements and, for example, reach around.
- It also advantageously results that the installation space required and manufacturing costs of the surgical microscope do not increase as the range of functions increases.
- the auxiliary operating mode is deactivated again.
- the deactivation can occur, for example, when the main operating mode is (re)activated, e.g. when an activation signal of the main operating mode is generated (which can then also be a deactivation signal of the auxiliary operating mode). It is also conceivable that a corresponding deactivation signal is generated to deactivate the auxiliary operating mode. It is also possible that the auxiliary operating mode can only be activated from the activated main operating mode. Alternatively, the auxiliary operating mode can also be activated independently of the activation state of the main operating mode.
- the surgical microscope can comprise activation means for activating the main and auxiliary operating modes, whereby these can be the same, but preferably different from one another.
- a mode can be activated whenever the corresponding mode is not activated.
- These activation means can be operated manually or acoustically, for example, or can comprise a user interface for user input.
- An activation signal can thus be generated, for example, by hand or foot actuation or by a voice command. It is also conceivable that an activation signal is generated by operating a graphical user interface such as a touch panel or screen, for example by selecting a desired movement mode there.
- the first and/or the further activation means can be designed, for example, as control element(s) of a hand control panel or a foot control panel.
- the hand control panel can be arranged, for example, on a handle of the surgical microscope.
- Such a control element can therefore be designed for operation by a hand, in particular a finger, or a foot of a user.
- a control element can be designed, for example, as a push button or key that generates an activation signal when pressed.
- the control element can be a control element that is freely configurable in terms of function, whereby various functions can be assigned to such a control element, e.g. by appropriate programming.
- the switching element can be a switching element that is permanently configured in terms of function, whereby a predetermined function is permanently and unchangeably assigned to it.
- the activation of the main operating mode takes place by actuating an activation means in a first actuation mode and the activation of the auxiliary operating mode in a different actuation mode.
- the corresponding activation means can thus be designed such that it can be actuated in different actuation modes.
- the activation of the auxiliary operating mode takes place when the activation means is actuated for at least a predetermined period of time, in particular longer than the predetermined period of time. In this case, the main operating mode can be activated when the activation means is actuated for less than the predetermined period of time.
- the activation means for activating the main operating mode is a switching means for switching between different main operating modes.
- main operating mode that is different from these can be activated if the activation means is operated in the first actuation mode and/or for less than the predetermined period of time. This also makes it possible to activate all the main operating modes in a predetermined order, i.e. to switch through them.
- the surgical microscope can also comprise deactivation means for deactivating the main and auxiliary operating modes, whereby these can also be the same, but preferably different from one another.
- the deactivation means can also be the same or different from the activation means.
- An activation signal or deactivation signal for the main or auxiliary operating mode can also be generated if at least one marker element with a predetermined identity is identified based on an image, i.e. by evaluating an image.
- the image can be generated, for example, by the tracking camera explained above, which can also be part of the surgical microscope or a microscopy system.
- the image that is evaluated for identification is generated by an image capture device of the surgical microscope for microscopic imaging.
- the main operating mode is activated or deactivated when a first identity is identified and the auxiliary operating mode is activated or deactivated when a different, further identity is identified.
- the activation of an operating mode can also lead to the deactivation of the previously activated operating mode.
- the activation means of one operating mode forms the deactivation means for deactivating another operating mode.
- the further movement is a translational movement along an optical axis of the microscope head, in particular in or opposite to the axial direction, which can be oriented from the microscope head to the object space.
- the first actuation of the operating element can control a translational movement in a first direction along the optical axis and a further actuation can control a translational movement in the opposite direction. It has been shown that a translational movement along the optical axis is more efficient than other Movements are less frequently desired by a user.
- assigning this movement to the auxiliary operating mode it is advantageous that other, more frequently desired movements can be assigned to the main operating mode and do not require any additional activation compared to the auxiliary operating mode. This in turn advantageously simplifies the operation of the surgical microscope, while at the same time enabling the translational movement described.
- the auxiliary operating mode is deactivated after a predetermined period of inactivity has elapsed.
- the period of inactivity refers to a period of time during which the operating element is not operated. It can be, for example, 5 seconds. If the auxiliary operating mode is activated and the operating element is not operated or is not operated according to a selected operating method or according to several selected operating methods, the auxiliary operating mode is deactivated. It is conceivable that after the auxiliary operating mode has been deactivated, the surgical microscope is put into a state in which both the main operating mode and the auxiliary operating mode are deactivated. In this case, the main operating mode must first be activated again for movement control.
- the main operating mode is activated after or with the deactivation of the auxiliary operating mode.
- the period of inactivity can be a period of time during which - regardless of whether the operating element is operated - no movement takes place, in particular no movement command is generated. It is conceivable that, despite the operating element being operated in the auxiliary operating mode, no movement takes place, e.g. due to a defect or a collision. In this case, too, the system can automatically switch to the main operating mode. This advantageously increases the operational reliability of the surgical microscope, particularly if the further movement is a translational movement along the optical axis, since the risk of collision with a patient or other surgical equipment is then reduced.
- the auxiliary control mode is deactivated when a trajectory limit of the movement is reached in the auxiliary control mode. If, for example, a movement along the optical axis is controlled in the auxiliary control mode, the auxiliary control mode can be deactivated when a focus limit is reached.
- This limit can, for example, be a limit of a range for permissible focus positions, whereby permissible focus positions can be predetermined. This also advantageously increases the operational reliability of the surgical microscope.
- the main operating mode is activated after the predetermined inactivity period has elapsed. This has already been explained above. This advantageously increases operational reliability in accordance with the previous explanations, while at the same time user-friendliness is increased, since after deactivation of the auxiliary operating mode, a movement can still be controlled without the main operating mode having to be activated again.
- the first movement method defines a translational movement in a plane that is oriented perpendicular to the optical axis.
- the first movement method defines a rotational movement.
- the defined rotational movement can, for example, take place around a point on the optical axis, in particular around a focal point.
- the rotational movement can take place around a reference point of the microscope head.
- the reference point can, for example, be arranged on one or more axes around which a microscope head attached to the stand can rotate, in particular at an intersection point of these multiple axes of rotation.
- the first movement method can also, in particular, define a direction of movement of the translational movement or the rotational movement.
- an activation signal for activating the auxiliary operating mode is generated haptically.
- the surgical microscope can comprise suitable activation means (first activation means) for this purpose, for example a manually operable activation means such as a push button, a switch or a different activation means for manual actuation.
- first activation means for example a manually operable activation means such as a push button, a switch or a different activation means for manual actuation.
- a manually operable activation means such as a push button, a switch or a different activation means for manual actuation.
- Such an activation means can in particular on the microscope head, in particular on its housing, or on a handle. This advantageously results in a simple and reliable activation of the auxiliary operating mode.
- the activation signal is generated acoustically, for example via a voice signal.
- the surgical microscope or a microscopy system comprising the surgical microscope can comprise means for voice-based activation, in particular at least one microphone and an evaluation device for evaluating acoustic signals.
- the activation signal for activating the auxiliary operating mode can then be generated depending on the evaluation of an acoustic signal.
- the operating element is designed for operation in a plurality of operating modes, wherein the auxiliary operating mode is activated for exactly one or several, but not all, selected operating modes.
- the auxiliary operating mode is activated for exactly one or several, but not all, selected operating modes.
- control element is designed as a joystick or a rocker switch. This results in a simple and cost-effective production of the surgical microscope.
- an activation signal for activating a main operating mode is generated with a further activation means, which is different from the first activation means for activating the auxiliary operating mode.
- a further activation means which is different from the first activation means for activating the auxiliary operating mode.
- different main operating modes can be activated with a graphical user interface. This advantageously results in reliable operation of the surgical microscope, in particular activation of the operating modes.
- Different main operating modes can in particular specify different movement modes with which the movement of the surgical microscope is controlled when the control element is actuated in a first actuation mode.
- a surgical microscope comprising at least one microscope head, at least one operating element for controlling the movement of the microscope head and at least one control device.
- the surgical microscope is configured in such a way that a method according to one of the embodiments described in this disclosure can be carried out with the surgical microscope.
- a microscopy system comprising the surgical microscope is also described.
- the microscopy system can comprise further activation means for activating a main operating mode and first activation means for activating the auxiliary operating mode.

- the translational longitudinal and translational transverse axes x, y are oriented perpendicular to each other and perpendicular to the optical axis 17.

- a rotational movement R2 of the microscope head 2 around the focal point and the transverse axis y can be controlled by operating it in a further operating mode. If an auxiliary operating mode M2 is activated, a movement of the microscope head 2 along and against the vertical axis z can be controlled by operating the operating element 16 in the first operating mode.
- Fig. 5 shows a schematic representation of movement modes of an auxiliary operating mode M2 (see Fig. 6) of a surgical microscope 1.

- Fig. 6 shows a schematic flow diagram of a method according to the invention. It is shown that a main operating mode M1 is activated. In this main operating mode M1, a movement of a microscope head 2 in a first predetermined movement is controlled by actuating an operating element 16 (see e.g. Fig. 2) in a first actuation mode. An auxiliary operating mode M2 is activated by generating an activation signal ASM2. In the auxiliary operating mode M2, i.e. in the activated state, a movement of the microscope head 2 in a further predetermined movement, which is different from the first movement, is controlled by actuating the operating element 16 in the first actuation mode.

- the auxiliary operating mode M2 is also deactivated after a predetermined period of inactivity has elapsed, with the surgical microscope being placed in a state M3 in which neither the main operating mode M1 nor the auxiliary operating mode M2 is activated upon such deactivation. It is of course conceivable that in the activated main or auxiliary operating mode M1, M2 a deactivation signal (not shown) is generated, by means of which the surgical microscope 1 is also placed in this state M3.
- Fig. 9 shows a schematic flow diagram of a method according to the invention in a further embodiment.

- These can differ in particular in the manner in which a movement of the microscope head 2 is controlled when an operating element 16 is actuated (see Fig. 2).
- the auxiliary operating mode M2 can then be activated by generating an activation signal ASM2.
- the The previously activated main operating mode M11, M12, M13 can be activated either by generating a corresponding activation signal or after a predetermined period of inactivity.
- Fig. 10 shows a schematic top view of an operating element 16 designed as a cross rocker switch 20.
- a switch longitudinal axis xs and a switch transverse axis ys are shown, which span a switch-specific coordinate system, with an origin of this coordinate system being arranged in a geometric center of gravity of the cross rocker switch 20.
- An actuation in a first actuation mode of this cross rocker switch 20 can take place by pressing on a first leg 21 of the cross rocker switch 20, which is then tilted about the switch longitudinal axis xs in a mathematically positive direction relative to the axial direction shown.
- An actuation in a second actuation mode of this cross rocker switch 20 can take place by pressing on a second leg 22 of the cross rocker switch 20, which is then tilted about the switch longitudinal axis xs in a mathematically negative direction relative to the axial direction shown.
- An actuation in a third actuation mode of this cross rocker switch 20 can be carried out by pressing on a third leg 23 of the cross rocker switch 20, wherein this is then tilted about the switch transverse axis ys in a mathematically positive direction relative to the axial direction shown.
- An actuation in a fourth actuation mode of this cross rocker switch 20 can be carried out by pressing on a fourth leg 24 of the cross rocker switch 20, wherein this is then tilted about the switch transverse axis ys in a mathematically negative direction relative to the axial direction shown.
- the actuation of the cross rocker switch 20 in the first actuation mode can control a movement of the microscope head 2 against the direction of a longitudinal axis x, which - as shown e.g. in Fig. 3 - runs through a focal point FP and is oriented perpendicular to a vertical axis z, the vertical axis z in turn being oriented parallel to the optical axis 17.
- the actuation of the cross rocker switch 20 in the second actuation mode can control a movement in the direction of the longitudinal axis x.
- the actuation of the cross rocker switch 20 in the third actuation mode can control a movement against the direction of a transverse axis y, which also runs through the focal point FP and forms a Cartesian coordinate system with the longitudinal and vertical axes x, z.
- the actuation of the cross rocker switch 20 in the fourth The actuation can control a movement in the direction of the transverse axis y.
- the actuation of the cross rocker switch 20 in the first actuation mode can control a movement of the microscope head 2 in the direction of the vertical axis z. Furthermore, the actuation of the cross rocker switch 20 in the second actuation mode can control a movement opposite to the direction of the vertical axis z.
- the cross rocker switch 20 When the cross rocker switch 20 is actuated in the third actuation mode and in the fourth actuation mode, no movement of the microscope head 2 can be controlled in the activated auxiliary operating mode M2, i.e. the actuation cannot cause any movement control. Alternatively, however, the function of the actuation can be retained in the activated main operating mode M1. Then the actuation of the cross rocker switch 20 in the third actuation mode can control a movement against the direction of the transverse axis y and the actuation of the cross rocker switch 20 in the fourth actuation mode can control a movement in the direction of the transverse axis y.
