Surgery system

A surgery system comprises a camera obtaining camera images, an OCT system, a data memory storing geometry data of a surgical tool 133 and a controller configured to identify a first portion of the tool in the camera images by object recognition using the geometry data; to determine, in the field of view, first locations where the tool is located and second locations aside of the tool; to trigger the OCT system to perform depth scans at the first and second locations; to identify a second portion 153 of the tool in the depth scans by object recognition using the geometry data; and to generate a first image 154 representing a third portion 157 of the tool based on the geometry data and the depth scans.

SURGICAL STEREOSCOPIC VISUALIZATION SYSTEM WITH MOVABLE HEAD MOUNTED DISPLAY
20170322410 · 2017-11-09 ·

A surgical stereoscopic visualization system having a microscope head, dual cameras mounted on or proximate the microscope head for real time video capture of a subject in an operative field, a video processing and display system to receive separate video streams from the cameras and to combine the separate video streams into a time-aligned stereoscopic image. The processed image is displayed on a matrix display screen in at least one movable head-mounted stereoscopic display. Movement of the head mounted display is accomplished with a support structure on a headband that accurately positions the display screen in front of the user's eyes, yet allows the user to precisely move the display screen either manually or by motorized means into and out of the user's line of sight, thereby facilitating uninterrupted use of the hands while working in the surgical suite.

Varioscope optical unit and microscope having a varioscope optical unit

A varioscope optical unit has a positive member (9) with a positive refractive power and a negative member (11) with a negative refractive power arranged along an optical axis (OA) so that the negative member follows the positive member along an observation direction (B). At least one of the members is displaceable along the optical axis. Each member has a first termination lens surfaces (23, 27) counter to the observation direction (B) and second termination lens surface (25, 29) in the observation direction. The second termination lens surface of the positive member and the first termination lens surface of the negative member are concave when viewed in the observation direction (B) and have radii of curvature of at most 500 mm. The second termination lens surface of the negative member is convex when viewed in the observation direction (B) and has a radius of curvature of at most 70 mm.
