Description

System overview The MediLive Video Camera System is a documentation system specially developed for use with surgical microscopes from Carl Zeiss. State-ofthe-art digital electronics provide a brilliant video image. The objects displayed on the monitor are rendered in their natural colors. A compact control unit (CCU) allows easy operation of the video camera. The keys for the most important functions are clearly laid out on a control panel on the CCU. The control keys for rarely used functions are accommodated on a flap which is usually closed. Each key is assigned a special function. There is no multiple assignment of functions to one key. To support the setting procedure, the system displays text information in the video image. The MediLive Video Camera System consists of modules which can be combined in many ways to form a video camera. Thus, it is possible to assemble a 1-chip or 3-chip CCD video camera for mono or stereo use as required by the customer and the application intended. The following figure shows how the modules can be combined with each other.

Description

Description of modules Camera block The camera block contains an optical system which directs the image produced by the surgical microscope to the built-in CCD compact video camera(s). Depending on the customer's requirements and the application intended, the camera block is fitted with different compact video cameras: –

one 1-chip compact camera for mono applications,

–

two 1-chip compact cameras for stereo applications,

–

one 3-chip compact camera for mono applications,

–

two 3-chip compact cameras for stereo applications.

The camera block can be inserted into a video objective lens. A centering component ensures correct optical alignment. Note: It is possible to insert the camera block rotated through 180° (cable support (1) pointing downward) in a video objective lens. In this case, the video image transmitted will be upside down. 1

Cable support for the connecting cable (system cable) to the camera control unit (CCU). Centering component is used to mount the camera block on the video objective lens. No optical alignment is necessary. CCD compact video camera(s) depending on the configuration chosen, one or two cameras are installed here. Housing contains the optical imaging system.

Description

Video objective lenses The video objective lenses are the optical links between the surgical microscope and the camera(s). Three different types are available: VOL 100 video objective lens The VOL 100 video objective lens can be mounted on every Carl Zeiss surgical microscope instead of the binocular tube. This lens directs 100 % of the light to the video camera(s) and is used: – for observation of the surgical field on the monitor only; – with surgical microscopes providing a second port for a binocular tube. Example: OPMI® ES. 1 Securing screw for locking the camera block in position. 2 Dovetail ring for mounting a video objective lens on the surgical microscope.
