Description

[Technical field]

[0001] Various aspects of the present disclosure relate to surgical microscope systems, and more particularly to arms for surgical microscope systems. [Background technology]

[0002] As surgery moves toward more digital workflows with the introduction of advanced surgical guidance technologies, one trend is a shift toward a "surgical cockpit" concept, where surgeons operate with precise, large-screen 3D visualization of tissue structures combined with on-screen surgical data captured in a single line of sight (as opposed to looking through binoculars and then at a data screen, which can lead to distractions).

[0003] One of the main value propositions of the 3D head-up approach to surgical microscopes is the improved surgeon ergonomics due to the microscope stack height. The 3D head-up view allows the surgeon to comfortably visualize the surgical workflow with better ergonomics and a natural posture (improved surgeon comfort) while observing the real-time surgical data on the screen to maintain an interconnected workflow (improved surgical confidence). The high stack height due to the incorporation of optical accessories (inverters, image injection, optical coherence tomography, laser filters, camera bridges, retinal viewing accessories, etc.) in the optics carrier is often a common difficulty faced by surgeons using traditional eyepieces. This can result in uncomfortable non-ergonomic positions due to the high microscope stack height. Moreover, the optics carrier arm is an obstacle to the surgeon's forward vision. 3D head-up monitors are often positioned at an off-center angle towards the right because the microscope optics carrier arm blocks the surgeon's view to the left. As a result, the surgeon's head may be tilted at an angle during surgery, which may reduce the ergonomics of the system. Summary of the Invention [Problem to be solved by the invention]

[0004] It is fair to say that it would be highly desirable to provide improved concepts for microscopy systems which improve the ergonomics of the surgeon. [Means for solving the problem]

[0005] Various embodiments of the present disclosure are based on the finding that the ergonomics of using a surgical microscope system can be improved for a surgeon by providing the surgeon with a straight-on view to visualize the surgical field without obstruction. Thus, according to the embodiments, a straight-on view of the surgical cockpit is achieved. In general, a surgical microscope system includes an arm attached to both the optics carrier (i.e., the actual microscope) and a base unit or ceiling mount. The arm can include a first section (also referred to as a "parallelogram section") that can be used to control the vertical height of the optics carrier above the ground, and a second section (or "optics carrier arm", "optics carrier section") located between the first section and the optics carrier. In general, the second section can be used to allow fine adjustment of the orientation and / or rotation of the optics carrier. In various embodiments of the present disclosure, this second section is adapted to create a free space that frees up the surgeon's view towards the display device of the surgical microscope system. Generally, this can be accomplished by redesigning the second section into an expanded "C- or V-shaped" configuration to provide a wider, more open view through the microscope stack.

[0006] According to various embodiments of the present disclosure, a surgical microscope system is provided that includes an optical system carrier that includes the microscope optics of the surgical microscope system. The surgical microscope system includes a display device for displaying image data recorded by an optical imaging sensor of the surgical microscope system. The surgical microscope system includes an arm. The arm includes a first section and a second section. The first section is configured to allow vertical and / or lateral adjustment of the position of the optical system carrier. The second section is attached to a suspension point of the first section and to the optical system carrier. The second section has a shape that creates a free space around a geometric axis between the suspension point and the optical system carrier such that an optical path between a central area of ​​the display device and a surgeon on the opposite side of the optical system carrier remains unobstructed by the second section. This optical path intersects with the geometric axis between the suspension point and the optical system carrier. By using a second section with a shape adapted in this way, the surgeon's view can be left largely unobstructed so that the surgeon has a good view of the display device without bending his / her neck.

[0007] Typically, the central region can be centered about a midpoint of the display device. For example, the central region can occupy at least 20% of the total area of ​​the display device. Typically, the portion of the surgical site that is focused on is displayed within the central region of the display device. The larger the central region that the surgeon has an unobstructed view of, the more useful the surgical cockpit becomes.

[0008] In general, such an unobstructed view can be achieved in various ways, but the following provides a specific implementation. For example, the shape of the second section can include a first subsection extending laterally outward from the suspension point, a second subsection extending downward from the first subsection, and then a third subsection extending inward from the second subsection back to the optical system carrier. In this way, the second subsection can be moved out of the way to provide a more open view of the light path toward the display device. In general, the above-mentioned shapes can be described as "C-shaped" or a sideways "V-shaped". In other words, the second section can be shaped substantially like the letter "C" or a sideways letter "V".

[0009] In various embodiments, the first subsection extends outward for at least 15 cm, which allows creating a free section around the optical path. At the other end, the third subsection can extend back inward for a similar distance, minus, for example, the space occupied by the optical system carrier, which allows determining the width of the central area that the surgeon can see unobstructed.

[0010] In various embodiments, the second subsection can extend downwardly at least 20 cm. For example, the second subsection can include a portion that extends straight down. This portion can occupy at least 40% of the vertical height of the second subsection. The height of the second subsection, and in particular the height of the portion that extends straight down, can determine the height of the central region of the display device.

[0011] For example, the transition between the first and second subsections can be tilted such that in the standby position of the first and second sections of the arm of the surgical microscope system a predefined distance is maintained between the first section and the tilted transition between the first and second subsections of the second section, so that the second section can be maintained in a freely rotatable state in the standby position of the arm of the surgical microscope system.

[0012] In some embodiments, the vertical height of the third subsection may be at least 20% greater than the lateral width of the third subsection, which may improve the stability of the attachment of the optical carrier to the arm of the surgical microscope system.

[0013] In general, various types of displays can be used, such as a display attached to a base unit of a surgical microscope system or a display attached to a wall of a surgical room. In both cases, a three-dimensional viewing experience can be achieved, for example, by using polarized glasses. Thus, the display device can be a display device for displaying three-dimensional image data.

[0014] In some embodiments, the optical system carrier is an optical system carrier without an optical eyepiece, thereby creating a field of view that allows the surgeon's field of vision to remain largely unobstructed. Alternatively, the optical system carrier can include an optical or hybrid eyepiece for the primary surgeon, and optionally a digital eyepiece for the assistant.

[0015] In various embodiments, the second section is shaped such that a first lateral distance between a subsection of the second section attached to the optical system carrier and the display device is less than a lateral distance between a subsection of the second section attached to the first section and the display device. In other words, the bottom of the second section can be tilted toward the display device, which leaves some space for a digital eyepiece for the assistant. Thus, the optical system carrier can include a digital eyepiece (e.g., for the assistant) on the side of the optical system carrier where the second section is attached.

[0016] In general, the optical system carrier may include an optical imaging device and various other components for generating image data to be displayed on the display device. These components may require electrical and / or data connections to a base unit of the surgical microscope system. Cables used for electrical and / or data connections may extend through the first and second sections of the arm. For example, the second section may include a cable duct and a removable cover for accessing the cables in the cable duct, for example for quick access to the cables extending between the base unit and the optical system carrier.

[0017] In some embodiments, the second section is adapted to rotate about a suspension point. For example, the second section can be adapted to rotate about a suspension point to position a major subsection of the second section (e.g., the second subsection shown below) to the left or right of the optical axis from the surgeon's perspective. In this way, an assistant surgeon sitting to the side can comfortably view the 3D monitor without his or her view being obstructed.

[0018] Various embodiments of the present disclosure provide a method for a surgical microscope system. The method includes providing an optical system carrier for the surgical microscope system, the optical system carrier including a microscope optical component of the surgical microscope system. The method includes providing a display device for the surgical microscope system, the display device adapted to display image data recorded by an optical imaging sensor of the surgical microscope system. The method includes providing an arm for the surgical microscope system. The arm includes a first section and a second section. The first section is configured to allow vertical and / or lateral adjustment of a position of the optical system carrier. The second section is attached to a suspension point of the first section and to the optical system carrier. The arm includes a second section having a shape that creates free space around a geometric axis between the suspension point and the optical system carrier such that an optical path between a central area of ​​the display device and a surgeon on an opposite side of the optical system carrier remains unobstructed by the second section, the optical path intersecting the geometric axis between the suspension point and the optical system carrier. The display device is mounted on one side of the optics carrier opposite the desired position of the surgeon.

[0021] Next, some embodiments will be described in more detail with reference to the accompanying drawings. However, other possible embodiments are not limited to the features of these embodiments described in detail.

[0025] In FIG. 1a, a schematic diagram of one embodiment of a surgical microscope system 100 is shown. The surgical microscope system includes an optics carrier 110 that includes the microscope optical components of the surgical microscope system. The surgical microscope system includes a display device 120 for displaying image data recorded by an optical imaging sensor of the surgical microscope system (shown in FIGS. 1b-1e). The surgical microscope system includes an arm. The arm includes a first section 130 and a second section 140. The first section is configured to allow vertical and / or lateral adjustment of the position of the optics carrier. The second section is attached to a suspension point of the first section and to the optics carrier. The second section has a shape that creates a free space around a geometric axis 150 between the suspension point and the optics carrier such that an optical path between a central area 125 of the display device and a surgeon on the other side of the optics carrier remains unobstructed by the second section. This optical path intersects with the geometric axis between the suspension point and the optics carrier. In Fig. 1a the base unit of the surgical microscope system is not shown. In general, the first section can be attached to the base unit of the surgical microscope system. Such an attachment is shown for example in Fig. 1b to Fig. 1e.

[0026] In Fig. 1a only the arms 130; 140 and the optical system carrier of the surgical microscope system are shown, the display device and the base unit of the surgical microscope system are shown in the following figures, e.g. Figs. 1b-1e.

[0027] The embodiments of the present disclosure relate to a surgical microscope system, i.e. a microscope system used during a surgical procedure. In general, a distinction is made between an actual microscope and an entire surgical microscope system, which in this case includes a microscope and various components used together with the optics carrier, such as an illumination system, an arm 130; 140 or a display device 120. In such a surgical microscope system, the actual microscope is called the "optics carrier" 110, since it includes the optical components of the microscope system. In general, a microscope is an optical instrument suitable for inspecting objects that are too small to be inspected (only) by the human eye. For example, a microscope can provide optical magnification of an object. In the case of modern microscopes, optical magnification is often provided for a camera or an imaging sensor. The optics carrier 110 can further include one or more optical magnification components used to magnify the view on the sample.

[0028] In general, there are various types of optical system carriers for surgical microscope systems. The optical system carriers discussed in this disclosure are for use in a surgical cockpit, where an external display is used as the primary means for the surgeon to view the surgical site. Thus, the optical system carrier only needs to include optical components and an optical imaging sensor, where the image data of the optical imaging sensor is displayed on the display device. In this case, the optical system carrier can be an optical system carrier without an optical (or digital) eyepiece.

[0029] Alternatively, the optical system carrier can include one or more eyepieces, for example an optical eyepiece or a hybrid eyepiece (optical eyepiece with optional digital overlay or replacement with a camera image) for use by the primary surgeon, and a (digital) eyepiece for an assistant, an example of which is shown in Figures 2a-c.

[0030] As mentioned above, in this surgical microscope system, an external display is used as the primary means for the surgeon to view the surgical site. This is achieved by recording the surgical site using an optical imaging sensor of the surgical microscope system, which may be included in the optical system carrier. In other words, the optical system carrier may include an optical imaging sensor. For example, the optical imaging sensor of the microscope may include or be an APS (Active Pixel Sensor) or CCD (Charge-Coupled-Device) type imaging sensor. For example, in the case of an APS type imaging sensor, light is recorded at each pixel using a photodetector and an active amplifier of the pixel. APS type imaging sensors are often based on CMOS (Complementary Metal-Oxide-Semiconductor) technology or S-CMOS (Scientific CMOS) technology. In the case of a CCD type imaging sensor, the incoming photons are converted into electronic charges at the semiconductor-oxide interface, and these electronic charges are then moved between capacitive bins in the imaging sensor module by the control circuit of the optical imaging sensor to perform imaging.

[0031] The image data is then displayed by the display device. For example, the base unit of the surgical microscope system may include one or more processors configured to process the image data and provide a display signal including the processed image data to the display device 120. The display device 120 is configured to display the (processed) image data recorded by the optical imaging sensor of the surgical microscope system.

[0032] 1b-1e show schematic diagrams of an embodiment of a microscope system, in this case showing the field of view of the surgeon system looking towards the display device 120. In FIG. 1b-1e, an embodiment of a surgical microscope system 100 is represented at 100b (FIG. 1b), 100c (FIG. 1c) and 100d (FIG. 1d and FIG. 1e). In FIG. 1b-1e, the display device 120 is shown (with a central portion 125 highlighted by a dashed box). In general, the display device can be located (or mounted) in multiple locations. However, to allow ergonomic viewing for the surgeon, the display device is located on the opposite side of the optical system carrier from the primary surgeon. In other words, the optical system carrier can be located (i.e., arranged) laterally between the display device and a location designated for the primary surgeon, i.e., a location that allows the use of a handle attached to the optical system carrier. As shown in FIG. 1b and FIG. 1c, the patient, and therefore the surgical site, can be located below the optical system carrier.

[0033] In general, there are various types of displays that can be included in a surgical microscope system. In particular, the display devices referred to in this context are external displays, i.e. displays that are not included in the optics carrier or in the arm of the surgical microscope system. Moreover, the display device can be arranged independently of the arm of the surgical microscope system, for example on a further arm of the surgical microscope system or on a wall of the operating room. In other words, the display device can be a display mounted on a further arm of the surgical microscope system (as shown for example in FIG. 1e for display device 120a) or on a separate stand or wall of the operating room (as shown for example in FIG. 1d / FIG. 1e for display device 120b). Thus, a surgical microscope system can include multiple display devices, which can be arranged in relation to the desired position for the surgeon within the field of view of the optical path through the geometrical axis mentioned above.

[0034] There are various display technologies that can be used for such a display. For example, the display device can include one of a liquid crystal display (LCD) or an organic light emitting diode (OLED) display. In some embodiments, a three-dimensional view experience can be generated. The display device can thus be a display device for displaying three-dimensional image data. For example, the display device can be configured to provide a three-dimensional view based on stereoscopic image data provided by an optical imaging sensor (or more precisely a stereoscopic sensor) of an optical system carrier. For example, the display device can be configured to output a three-dimensional representation of the image data, for example using a polarizing filter. The surgeon can wear glasses that include a corresponding polarizing filter.

[0035] The surgical microscope system further includes an arm having a first section 130 and a second section, the second section being of particular importance since it is adapted to create a free space about a geometric axis.

[0036] The arm includes a first section configured to allow vertical and / or lateral adjustment of the position of the optical system carrier. For example, as shown in Fig. 1b-1e, the first section can be attached to a base unit (including one or more processors) of the surgical microscope system and to a second section of the arm. In other words, the first section can be disposed between the base unit and the second section, and the second section can be attached to the base unit. For example, the first section can be moved with the aid of hydraulic or servo motor assistance. In general, the first section can be referred to as a parallelogram section of the arm of the surgical microscope system. In contrast, the second section can be referred to as an optical system carrier arm or an optical system carrier section.

[0037] The second section is attached to the first section, i.e. to the suspension point of the first section and to the optical system carrier. The suspension point of the first section can be a part of the first section located above (directly above) the optical system carrier. In other words, at least one part of the optical system carrier and the suspension point can be intersected by a further geometric axis extending parallel to gravity. In some embodiments, the second section is adapted to rotate about the suspension point. For example, the second section can be adapted to rotate about the suspension point so as to position a major subsection of the second section (e.g. the second subsection shown below) to the left or right of the optical axis from the surgeon's point of view. This is shown for example in FIG. 1f. FIG. 1f shows a schematic diagram of one embodiment of a surgical microscope system with an arm including a first and a second section, where the second section can rotate (i.e. pivot) about a suspension point that is part of the first section. In other words, the C-arm (i.e., the second section) can be swiveled around so that the optical carrier (or optical system carrier) can be positioned to either the left (side) or right (side).

[0038] As mentioned above, the second section has a shape that creates free space around the geometric axis 150 between the suspension point and the optical system carrier so that the optical path between the central area 125 of the display device and the surgeon on the other side of the optical system carrier remains unobstructed by the second section. In this context, the term "optical path" may not refer to a single beam between the surgeon and the display device, but rather to the area that the surgeon can see unobstructed, as shown in FIG. 1d. In FIG. 1d, a triangle 155 is shown depicting the optical path between the surgeon and the display devices 120a and 120b, with an acute angle at the corner facing the surgeon. As can be seen from this figure, optimally, the full height of the display device is visible through the optical path unobstructed. However, this may not be a prerequisite, since the most important information is often displayed within the central area of ​​the display device. For clarity, the central area is centered around the midpoint of the display device. The central region can occupy at least 20% (or at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%) of the total area of ​​the display device. For example, the central region can occupy at least 40% (or at least 50%, at least 60%, at least 70%, at least 80%, at least 90%) of the total horizontal width of the screen of the display device and / or can occupy at least 40% (or at least 50%, at least 60%, at least 70%, at least 80%, at least 90%) of the total vertical height of the screen of the display device.

[0039] This optical path intersects with a geometric axis between the suspension point and the optical system carrier. In other words, at least a portion of the optical path intersects with the geometric axis between the suspension point and the optical system carrier. Moreover, the geometric axis can be centered on the optical path, i.e. the surgeon can look through the second section towards the central area through the geometric axis. The display device can be positioned such that the surgeon looks towards the display device through the free space created by the shape of the second section. In other words, the central beam of the optical path (between the surgeon and the display device) can intersect with the geometric axis.

[0040] This can be accomplished, for example, in a variety of shapes and configurations. For example, the second section can be shaped like a sideways "O" where the recess in the sideways "O" creates a free space. However, preferably, the second section can be shaped like a "C" or a sideways "V." In other words, the second section is substantially shaped like the letter "C" or the letter "V" turned on its side. In some instances, the shape can also be described as that of a square bracket or a circular bracket.

[0041] By redesigning the arms of the optics carrier to have an expanded "C- or V-shaped" configuration, a wider and more open view through the microscope stack can be achieved. This allows an unobstructed front-on view of the surgical monitor, resulting in better hand-eye coordination and a more natural working position without the need to tilt the head off-center. In addition, this allows the surgeon to better observe the clinical setting and workflow in front of him / her. This improves the surgeon's workflow efficiency based on unobstructed visualization of the required tools and easy identification of data readouts from critical surgical instruments. Figures 1b and 1c show unobstructed front-on views of the surgical monitor for both the upper and the temporal surgical positions. Figures 1d and 1e show unobstructed front-on views of both the stand monitor 120a and the larger monitor 120b positioned further away.

[0042] More specifically, the shape of the second section may include a first subsection 142 extending laterally outward from the suspension point, a second subsection 144 extending downwardly from the first subsection, and then a third subsection 146 extending inwardly from the second subsection back toward the optical system carrier.

[0043] The first subsection 142 may extend laterally outward from the suspension point. However, the first subsection does not have to be directly attached to the suspension point. Instead, the second section may include a further subsection disposed between the first subsection and the suspension point. This further subsection is shown in FIG. 1a as a wide rectangle. The first subsection 142 is attached to this rectangle and extends laterally outward from the suspension point. In this context, the term "extending laterally outward" refers to two properties of the first subsection: that it extends away from the lateral position of the suspension point (i.e. outward) and that it includes a substantial lateral extent (e.g. the first subsection extends outward for at least 15 cm), i.e. a lateral extent that causes the transition between the first subsection and the second subsection to be outside the geometric axis between the suspension point and the optics carrier. In other words, the first subsection can guide the second section away from the geometric axis between the suspension point and the optics carrier.

[0044] The second subsection 144 may extend downward from the first subsection. In other words, the first end of the second subsection 144 attached to the first subsection may be located above the second end of the second subsection 144 attached to the third subsection. Moreover, the second subsection may be attached to both the first subsection and the third subsection (e.g., via a transition section) and may be located between the first subsection and the third subsection. For example, the second subsection may extend downward by at least 20 cm (or at least 25 cm, at least 30 cm, at least 40 cm). In other words, the first end of the second subsection 144 attached to the first subsection may be located above the second end of the second subsection 144 attached to the third subsection by at least 20 cm (or at least 25 cm, at least 30 cm, at least 40 cm). For example, the second subsection may include a portion that extends straight down (i.e. (substantially) parallel to gravity). This portion may occupy at least 40% (or at least 50%, at least 60%, at least 70%, at least 80%) of the vertical height of the second subsection. In other words, this portion may have a vertical height of at least 10 cm (or at least 12 cm, at least 15 cm, at least 20 cm, at least 25 cm, at least 30 cm, at least 35 cm).

[0045] The third subsection 146 can then extend inwardly back from the second subsection towards the optical system carrier. In this context, the term "inwardly" means that the third subsection extends from the second subsection towards the geometric axis between the suspension point and the optical system carrier. In general, the third subsection can be at the same vertical level as the optical system carrier. Thus, the third subsection can extend laterally towards the optical system carrier at the same level as the optical system carrier. For example, the optical system carrier can be attached to the third subsection, for example via an additional subsection or via an interposer.

[0046] In some embodiments, the second section further comprises transition subsections arranged between the individual subsections and providing a step-by-step transition between the individual sections. In the case where a transition is provided between the first and second subsections, this transition can be inclined such that the second section does not collide with the first section in the standby position of the arm of the surgical microscope system. For example, the second section can comprise a curved edge, which allows the optical system carrier to be moved to the standby position without colliding with the microscope arm. In other words, the transition 143 between the first and second subsections can be inclined such that a predefined distance 143a is maintained between the first section and the inclined transition between the first and second subsections of the second section in the standby position of the first and second sections of the arm of the surgical microscope system. This distance 143a is shown in FIG. 1a. For example, the transition between the first and second subsections can be inclined such that the inclination of the transition approximates the inclination of the first section in the standby position of the surgical microscope system. For example, the predefined distance can be at least 2 cm (or 3 cm or 4 cm) and / or at most 12 cm (or 10 cm or 8 cm or 6 cm).

[0047] As mentioned above, the optical system carrier can include an optical imaging device and various other components for generating image data to be displayed on the display device. These components may require electrical and / or data connections to the base unit of the surgical microscope system. In addition, the optical system carrier can include an illumination system of the surgical microscope system, or fiber conductors can be used to guide light to the optical system carrier to be delivered to the surgical site via the optical system carrier. All of these features may require connections between the base unit of the surgical microscope system and the optical system carrier. Thus, the second section (as well as the first section) can include a cable duct. In addition, the second section can include a removable cover 148 to access the cables in the cable duct. For example, the removable cover can be located on the side of the second section facing away from the geometric axis between the suspension point and the optical system carrier. A detailed view of such a cable duct and cover is shown in FIG. 6.

[0048] In the context of the present disclosure, the terms "lateral" or "horizontal" are defined parallel to the floor level of the room in which the surgical microscope system is used, which may be perpendicular to gravity. The term "vertical" is defined perpendicular to the floor level and therefore parallel to gravity. Correspondingly, the terms "upper" and "lower" may be defined with respect to the vertical direction, i.e. if a first part is arranged above a second part, this means that at least a majority (or all) of the first part is arranged vertically above the second part (i.e. vertically further away from the floor level of the room in which the surgical microscope system is arranged), and if a first part is arranged below the second part, this means that at least a majority (or all) of the first part is arranged vertically below the second part (i.e. vertically closer to the floor level of the room in which the surgical microscope system is arranged).

[0049] Further details and aspects of the surgical microscope system are referred to in connection with the proposed concept or one or more embodiments described above or below (e.g., Figures 2a-7). The surgical microscope system may include one or more additional optional features corresponding to one or more aspects of the proposed concept or one or more embodiments described above or below.

[0050] 2a-c show schematic diagrams of one embodiment of a surgical microscope system 200 with two eyepieces 115; 160, each viewed from a different perspective. In general, the surgical microscope system of Figs. 2a and 2b can be implemented similarly to the surgical microscope system 100 (100; 100b; 100c; 100d) of Figs. 1a-1e. However, unlike the embodiment shown in relation to Figs. 1a-1e, the surgical microscope system 200 of Figs. 2a-2c includes a first eyepiece 115 (for the main surgeon) and a second eyepiece 160 (for the assistant). In other words, the optical system carrier can include a digital eyepiece 160 on the side of the optical system carrier where the second section is attached and / or an optical or hybrid eyepiece 115 on the side of the optical system carrier facing the surgeon. Generally, any combination is possible, such as a surgical microscope system with a first eyepiece 115 but not a second eyepiece 160, a surgical microscope system without a first eyepiece 115 but with a second eyepiece 160, a surgical microscope system without any eyepieces, or a surgical microscope system with both eyepieces 115;160. For example, the first eyepiece can be an optical eyepiece or a hybrid optical and digital eyepiece, and the second eyepiece can be a digital eyepiece. In this context, the term "digital eyepiece" refers to the fact that the view on the specimen through the eyepiece is generated solely by a display integrated within or connected to the eyepiece. The term "hybrid optical and digital eyepiece" refers to the fact that the eyepiece provides both a purely optical view and a view generated by a display, and optionally a digitally overlaid view on the optical view. In general, the eyepieces can also be referred to as binoculars.

[0051] 2a-c show a curved optics support arm 140 that allows for a main binocular (eyepiece) and a lateral auxiliary binocular (eyepiece). The second section can be partially tilted towards the display device so that the second eyepiece 160 can be placed. In other words, the second section can be shaped such that a first lateral distance between the subsection of the second section attached to the optics carrier and the display device is less than a lateral distance between the subsection of the second section attached to the first section and the display device. In other words, a relatively lower part of the second section can be tilted towards the display device. Such an arrangement is shown in FIGS. 2a-c, where the entire second subsection of the second section is tilted. Another implementation is shown in FIG. 5c, where only a portion of the second subsection is tilted and the main part of the second subsection extends straight down.

[0052] Further details and aspects of the surgical microscope system are referred to in connection with the proposed concept or one or more embodiments described above or below (e.g., Figures 1a-1e, 3a-7). The surgical microscope system may include one or more additional optional features corresponding to one or more aspects of the proposed concept or one or more embodiments described above or below.

[0053] In Figures 3a-3h, various different shapes of the part of the second section 140 of the arm of the surgical microscope system 300a-300h are shown. For example, these various shapes can be used to implement the second section of the arm of the surgical microscope system shown in Figures 1a-2c, 4-6. According to Figures 3a-3h, a "C-shaped or V-shaped" optics carrier arm can be shown that provides a more open view through the microscope stack.

[0054] FIG. 3a shows a "C-shaped" second section 140 with first, second and third subsections that extend substantially laterally (first and third subsections) or vertically (second subsection) with only slight transitions between each subsection. FIG. 3b shows a shallow "V-shaped" second section, where the first and third subsections extend substantially laterally and the second subsection has a shallow "V" shape that is inverted. FIG. 3c shows a "C-shaped" second section that resembles a cursive C, where the first and third subsections extend substantially laterally and the second subsection extends downwards and outwards at the same time. The second section in FIG. 3d is similar to the second section in FIG. 3b, where the second subsection has a more pronounced "V" shape. In the case of Figures 3e and 3f, the first subsection extends substantially laterally outward, the second subsection extends directly downward, and the third subsection extends downward and inward at the same time. The second section of Figure 3g is similar to the second section of Figure 3a, where the second subsection has a rounded shape that extends laterally outward and then returns laterally inward as the second subsection meets the third subsection. The second section of Figure 3h is also similar to the second section of Figure 3a, where the second section includes a fourth subsection that is located between the third subsection and the optics carrier and extends both downward and inward in order to lower the lateral position of the optics carrier 110 above ground.

[0058] 5a-5c show schematic views of the second section 140 of the arm of the surgical microscope system 500 from different viewpoints. For example, the surgical microscope system 500 of FIG. 5a-5c can be implemented similarly to the surgical microscope systems 100-300h of FIG. 1a-3h. In FIG. 5a-5c, a front conceptual view and a side conceptual view of the novel optical system carrier arm are shown. For example, according to FIG. 5a-5c, a detailed view of the second section used in FIG. 1a-2c can be shown. As is clear from FIG. 5c, the vertical height of the third subsection can be at least 20% greater than the lateral width of the third subsection. In this way, the stability of the mounting of the optical system carrier 110 in the second section can be improved.

The surgical microscope system may include one or more additional optional features corresponding to one or more aspects of the proposed concept or one or more embodiments described above or below.

[0060] A cable duct is shown integrated in the second section in Fig. 6.

The method comprises a step 730 of preparing an arm of the surgical microscope system, the arm comprising a first section and a second section. The first section is configured to allow vertical and / or lateral adjustment of the position of the optical system carrier. The second section is attached to a suspension point of the first section and to the optical system carrier. The arm is provided with a second section having a shape that creates free space around a geometric axis between the suspension point and the optical system carrier such that an optical path between a central region of the display device and a surgeon on an opposite side of the optical system carrier remains unobstructed by the second section, the optical path intersecting the geometric axis between the suspension point and the optical system carrier. The display device is provided on one side of the optical system carrier opposite a desired position for the surgeon.
