A sterile sheath and methods for enclosing a confocal endomicroscopy (CEM) scanner probe with the sterile sheath are provided. The scanner probe includes a probe shaft, a probe tip, a probe body, and a probe umbilical. The sterile sheath for enclosing the CEM scanner probe includes a sheath tube configured to receive the probe shaft and has a distal tube end, a proximal tube end, a sheath tip mounted at the distal tube end of the sheath tube, and a sheath socket configured to receive the probe body. The sheath socket has a distal socket end and a proximal socket end. The proximal tube end of the sheath tube is fixed to the sheath socket at the distal socket end. The sterile sheath further includes a sheath lock ring and a sheath drape mounted on the sheath socket at the proximal socket end with the sheath lock ring.

A method for performing auto-focus in a camera is disclosed. The method includes: receiving, from a tracking system for tracking a position of a medical instrument, a signal; determining, based on the received signal, that the medical instrument is removed from a field of view of the camera; in response to determining that a continuous auto-focus mode for the camera is enabled: retrieving, from a database, a first focus distance value representing a focus distance that was most recently set with intent for the camera; and automatically updating a focus distance of the camera to the first focus distance value.

A surgical microscope for visualizing a tissue region contains an illumination device with a light source and an illumination beam path for illuminating an object region with an object plane and an observation device having an observation beam path for imaging the object region with the object plane into an observation plane. A first polarizer can be coupled into the illumination beam path and is suitable for polarizing the illumination light in a first orientation. A polarizer, which can be coupled into the observation beam path, has a second orientation at an angle between 80° and 100° relative to the first orientation. In a first mode, the light source emits illumination light in a first wavelength range between 450 nm and 550 nm, the first polarizer is coupled into the illumination beam path, and the second polarizer is coupled into the observation beam path.

Examples relate to a microscope system comprising a Light-Emitting Diode (LED)-based illumination system and at least one image sensor assembly, and to a corresponding system, method and computer program. The LED-based illumination system is configured to emit radiation power having at least one peak at a wavelength that is tuned to an excitation wavelength of at least one fluorescent material and/or to emit radiation power across a white light spectrum, with the light emitted across the white light spectrum being filtered such that light having a wavelength spectrum that coincides with at least one fluorescence emission wavelength spectrum of the at least one fluorescent material is attenuated or blocked. The at least one image sensor assembly is configured to generate image data, with the image data (at least) representing light reflected by a sample that is illuminated by the LED-based illumination system. The microscope system comprises one or more processors, configured to process the image data to generate processed image data.

Methods, apparatuses, and systems for using speech input to control a surgical robot are disclosed. A surgical robot is disclosed that can be controlled by a surgeon using speech input in a conversational manner. The surgical robot is provided either general commands or specific instructions, assessing whether the instructions can be completed within the capabilities of the available hardware and resources, and seeking approval from the surgeon prior to executing the instructions. Alternatively, the embodiments disclosed allow the surgeon to perform an action that cannot be safely completed by the surgical robot.

A medical imaging device, comprising a illumination unit, can be configured to illuminate a tissue area with light from a first spectral range, comprising a range of visible wavelengths, and with light from a second spectral range, which is different from the first spectral range, an imaging unit, configured to detect light from the first spectral range and to generate a first image of the tissue area on the basis of the detected light from the first spectral range and furthermore configured to detect light from the second spectral range and to generate a second image of the tissue area on the basis of the detected light from the second spectral range, and a superposition unit, configured to generate a superimposed image on the basis of the first and second image in such a way that, in the superimposed image, on the basis of a visual highlighting, it is possible to identify whether and where the tissue area comprises highlight regions which are characterized by an increased emission of light from the second spectral range in comparison to other regions of the tissue area. The document furthermore relates to a method for image-based support for a medical intervention, and to a use of an imaging device in such a method.
