Embodiment Construction

[0107] Elements corresponding to each other are marked with the same reference numerals. For the sake of clarity, the description will not be repeated.

[0108] figure 1 A surgical lighting device with a stereoscopic image acquisition device according to the prior art is schematically shown. The surgical lighting device includes a plurality of LEDs 2 . Two objective lenses 5 close to each other are arranged near the center point of the surgical lighting device, and the two objective lenses 5 constitute the object-side channel end of the optical channel of the stereoscopic image acquisition device.

[0109] The separation between the surgical lighting device and the object being imaged using the stereo image capture device is variable. Therefore, the solid angle is variable. However, since the stereo base (ie, the space between the two objective lenses 5 ) is small, the solid angle and thus the stereoscopic effect of the stereo image are small. There is still a risk that b...

Abstract

A surgical illumination device (1) having illuminating means (2) distributed over an area (A) and a stereoscopic image acquisition device (10) having two optical channels (10a, 10b) which each generate a monoscopic image of an illuminated object (6). At least three optical channels can be present, each of which may be arranged with its object-side channel end (D1, D2, D3; C1, C2, C3, C4, C5; OL, OR, UL, UR) inside the area (A) at its periphery. Two object-side channel ends can be arranged at a same distance to at least one other channel end. If one (D2, C3, UR) of the optical channels related to the two object-side channel ends (D2, D3; C3, C4; OL, UR) is no longer supplying a monoscopic image, the other one (D3, C4; OL) of the optical channels related to said two object-side channel ends can generate a stereoscopic image.

Description

technical field [0001] The invention relates to an operation lighting device and a stereoscopic image acquisition method. Background technique [0002] In modern operating rooms, surgical lighting equipment does not only have the task of optimally illuminating the area of ​​the patient where surgery is to be performed. In addition to lighting devices, modern surgical lighting equipment often includes video cameras in order to document the procedure. These cameras can be equipped as stereoscopic image acquisition devices for acquiring surgical stereoscopic images. [0003] For example, acquired stereoscopic images can be sent to a 3D screen, and assistants or students can track the operation and the surgeon's individual movements or manual manipulations at very close range. This principle is popular not only in surgery, but also, for example, in dentistry or pathology. [0004] A conventional stereoscopic image acquisition device arranged in a space-saving manner at the ce...
