The invention is directed to a medical therapeutic and/or diagnostic apparatus having a function unit ( ) and a position detecting device ( ). A further detecting device ( ) is mounted so as to be fixed in position and orientation and is separated from the position detecting device ( ) by a signal path. The position detecting device ( ) operates together with the additional detecting device ( ). The position detecting device ( ) can be changed during operation with respect to position and orientation relative to the function unit ( ).

Medical therapeutic and/or diagnostic apparatus having a position detecting device

An OCT-supported surgical system includes an OCT module that includes a surface scanner, the position of which can be sensed by a position sensing unit, and an evaluation and display unit, which is connected to the OCT module and to the position sensing unit in order to be able to correlate a tissue-differentiated tomogram of a specimen sensed by the OCT module with preoperatively produced specimen data.

Surgical system supported by optical coherence tomography

In an apparatus for the image-supported treatment of a work object with a work object data unit and a display unit for the display of work object data from the work object data unit, the display unit makes possible a simultaneous visual sensing, with freedom of head movement, of the instantaneous work object and of the work object data from the work object data unit.

Apparatus for image-supported treatment of a work object

In an operation microscope (1) with an integrated navigation system (3), the control of the navigation system (3) takes place by means of an operating unit (5, 7, 9) that can be operated directly from the operation microscope (1) and which acts on a navigation system control menu (11) that is reflected into the visual field of the operation microscope (1).

Process for the operation of an operation microscope

A medical therapeutic and/or diagnostic appliance includes an arrangement that senses a position and attitude at any given time, and that includes a first sensing unit on the therapeutic and/or diagnostic appliance and a second sensing unit having a fixed location and attitude and arranged to be separated from the first sensing unit by a signal path. The first sensing unit is constructed, for reasons of sterilization and of position sensing, as an attachment that can be detached from the medical therapeutic and/or diagnostic appliance when in use. A coupling device is provided on the medical therapeutic and/or diagnostic appliance for installation of the attachment over a sterilizing sheath surrounding the therapeutic and/or diagnostic appliance.

Medical therapeutic and/or diagnostic appliance with a sterilizable

In a procedure for correlating different coordinate systems in computer-supported, stereotactic surgery, without the use of additional referencing markers, partial topographical information is collected by means of a surgical microscope mounted on a carrier system, and this partial topographical information is spatially correlated with the diagnostic data generated prior to surgery using a suitable correlation algorithm.

Procedure for the correlation of different coordinate systems in

A stereotactic adapter on which a surgical therapeutic and/or diagnostic instrument is reproducibly mounted and attached to a surgical microscope that can be positioned in several spatial degrees of freedom. A position recognition system integrated in the surgical microscope permits safe positioning of the instrument used, given the geometric arrangement and the geometric dimensions of the surgical microscope, the adapter, and the instrument.

Stereotactic adapter and procedure for its use

For the use of an Operation Microscope, in computer-supported stereotactic surgery, a set of preoperative diagnostic data of a patient is first generated by means of an image-forming preoperative diagnostic procedure. The surgeon then plans the operation path on a central control unit and determines which of the stored diagnostic images are to be reflected into the observation optics of the operation microscope. During the operation, the operation microscope, arranged on a motorized support system, is caused to travel in a motorized manner along the established operation path, and the diagnostic images corresponding to the prior selection are selectively reflected into the observation optics of the operation microscope without a correlation having to be carried out of the respective individual coordinate systems.

A stand is provided for mounting various loads and is balanced at least partially automatically. The stand includes a plurality of interconnected elements defining one or more axes about which the stand is movable. An open-loop or closed-loop control circuit is provided for at least one of the axes and detects the unbalanced state about the one axis. The control circuit allows a torque compensating device to operate on the one axis until a state of equilibrium is obtained.

Stand for mounting various loads

A defined determination of the field of view observed through a surgical microscope is made. To achieve this determination, the relative current position of the plane of the field of view to the position of an object detail of interest is detected in a sighting method with the aid of a position detection system operating according to the laser triangulation principle. As soon as the plane of the field of view and the object detail are coincident, then with the aid of detected optical system data, the position of the object detail with reference to the surgical microscope is determined and, with the detected coordinates of the surgical microscope, the position of the field of view is determined in space. The position detecting system required for this purpose operates on an optical basis and can be integrated into the optics of the surgical microscope.

Method of operating a surgical microscope arrangement for

An instrument is mounted on a motorized positioning mechanism for providing a contactless guidance of the instrument. A transmitting unit and a receiving unit are arranged in a defined relative position to an operator and the instrument so that an evaluation unit positions the instrument via corresponding control signals with the aid of the registered signals of the receiving unit. A preferred application is the contactless guidance of a surgical microscope which tracks the head movements of the surgeon.

Optical guide system for spatially positioning a surgical microscope

A motorized stand for positioning medical therapeutic or diagnostic instruments is mechanically coarsely balanced by weights. A defined positioning of the medical instrument is determined by means of several drive units with integrated angle transducers. Operating safety is additionally ensured, in the event of failure of a drive unit, by the use of two angle transducers per drive unit. One angle transducer is coupled to the drive motor of each drive unit. The other angle transducer is independent of the drive motor.

Motorized stand

The invention relates to a high-precision autofocusing arrangement for a stereomicroscope wherein a bar-shaped marking is projected via a cylinder optic on an object. The imaged bar-shaped marking is at least in one dimension less or equal to the resolution of the viewing beam path. A region of the objective not used optically is selected for projection as the pass-through pupil.
