A system for short pulse laser eye surgery and a short pulse laser system, in which a beam guidance device passes through a corresponding articulated arm, and through an applicator head and a microscope head of the system, which is movable in a three-dimensional volume both independently of one another as well as connected to each other. The system also includes, an easy-to-use patient interface with a one-piece contact element, a computer program product for methods of the incision guidance and sequentially operating referencing methods with patient interfaces containing markings.

A medical stand apparatus includes a cylindrical lower arm that accommodates an upper arm divided into sections, so that only the lower arm is visible from the outside and so that a drape can tightly be fastened to the lower arm. The upper arm sections are connected to each other through a shaft that is guided along an arc groove of a bracket. This configuration is beneficial to reduce a diameter of the lower arm when the upper and lower arms are curved.

A microscopy system includes a microscope, a stand configured to mount the microscope and including a drive device configured to move the microscope, a detection device configured to detect a spatial position of a target fastened to a body part or to an instrument, wherein the position detection device includes the target with at least one marker element and an image capture device configured to optically capture the target. The microscopy system further includes at least one control device configured to operate the microscopy system according to the detected position of the target, wherein the position detection device is configured to determine the position of the target by evaluating a two-dimensional image of the image capture device. In addition, a method for operating the microscopy system is provided.

A medical apparatus is described for providing visualization of a surgical site. The medical apparatus includes an electronic display disposed within a display housing. The medical apparatus includes a display optical system disposed within the display housing, the display optical system comprising a plurality of lens elements disposed along an optical path. The display optical system is configured to receive images from the electronic display.

In one aspect there is provided a medical navigation system, comprising a computing device having a processor coupled to a memory, a tracking camera for tracking medical instruments, and a display for displaying an image. Tracked medical instruments may have attached thereto an indicator device having a visual indicator. The indicator device is positioned in view of a user during the medical procedure, and is configured to receive, from the medical navigation system, data indicating a quality of the tracking of the one or more instruments, and to display, using the visual indicator, the data indicating the quality of the tracking.

A mounting device for a stand device for arrangement in the operating room and to position or displace a medical apparatus in the operating room, in particular by means of a rotational movement, incorporates a mounting apparatus, which extends along an axis of rotation in a longitudinal direction and has a cavity, which in particular is cylindrical and which is oriented in the longitudinal direction, for accommodating a rotatably supportable connection component of the stand device, in particular a spindle; and an adjustment apparatus for arranging the connection component in a position, which can be predefined, in relation to the mounting apparatus; wherein the mounting device forms a rotational coupling for supporting the connection component on the mounting apparatus, which rotational coupling can be adjusted about the axis of rotation. The invention further relates to a mounting system including such a mounting device.

A stand includes first to fourth links, first to fourth joints, a front link, first to fifth extension links, and first to fourth extension joints. The first to fourth links are arranged in a parallelogram configuration, wherein the first and third links are arranged on opposite sides and the second and fourth joints are arranged in a diagonal direction. The front link extends from the first link. The first extension link is rotatably connected to the second joint. The second extension link is rotatably connected to the first extension joint. The third extension link is rotatably connected to the second extension joint. The fourth extension link is arranged between the third extension joint and the fourth extension joint. The fifth extension link is arranged between the first joint and the second extension joint. The first, fourth, and fifth extension links are in parallel with one another.

A mount for an optical apparatus having an image recording unit and an image rendering unit includes a first securing device for the recording unit, a second securing device for the rendering unit, and a connecting rail interconnecting the securing devices. The connecting rail is arranged so as to be displaceable in the y-direction in relation to the second securing device via a linear actuator. The first securing device includes a rotation device arranged so as to be rotatable about an axis of rotation extending in the x-direction. The mount includes a controller which is configured to displace the connecting rail in the y-direction in relation to the second securing device via the actuator when the first securing device is rotated about the tilt axis such that the distance between the focal point and the second securing device is kept constant within a certain interval.
