PANOVIEW ULTRA laparoscopes: optics, 4K use and handling

What PANOVIEW ULTRA is

According to Richard Wolf, PANOVIEW ULTRA telescopes are designed for high-resolution laparoscopic imaging with natural colours. They are optimised for Ultra HD and 4K, remain sharp up to the edge of the image and work with the same light cable as 10 mm telescopes. The full product information is on the PANOVIEW ULTRA page.

They belong to the system approach of Richard Wolf, where telescopes, light and signal processing are developed together; see the Richard Wolf brand page for the wider range.

Optical design and light transmission

Larger-aperture fibre optics transmit more light, which helps in large cavities and with high-resolution cameras. ED (extra-low dispersion) glass lenses reduce image defects such as colour fringing, and the fibre optics are lead- and arsenic-free. Richard Wolf also specifies low colour shift for a natural white-light appearance.

Many laparoscopes use the rod-lens principle commonly called Hopkins; see our article on Hopkins rod-lens versus chip-on-tip for the difference to chip-on-tip designs. Confirm the exact design and technical data of PANOVIEW ULTRA with your supplier when preparing a specification.

Autoclave durability and long-term image quality

Reusable telescopes must survive repeated steam sterilization. Richard Wolf states that PANOVIEW ULTRA telescopes show hardly any transmission loss after 500 autoclave cycles. For a hospital this matters because image quality degradation is gradual, and nobody notices a dimming picture until the telescope is compared with a new one.

Still, durability depends on handling. Track the number of cycles per telescope, test the light transmission regularly and read our guide to rigid endoscope sterilization for loading and tray advice.

• Always use a protective holder in the tray.
• Inspect the lens windows and the shaft for scratches and dents after each cycle.
• Never lever the telescope against the trocar.
• Run a leak test where the IFU recommends it.

Sizes, angles and 4K compatibility

Laparoscopes typically come in diameters such as 5 and 10 mm and viewing angles of 0°, 30° and in some designs 45°; see laparoscope angles 0, 30 and 45 for how to choose. The specific diameters, lengths and angles of PANOVIEW ULTRA telescopes should be confirmed in the current order list from the supplier.

For 4K use, the telescope must match the camera: the ENDOCAM Logic 4K gives native 4K output and PANOVIEW ULTRA is optimised for such imaging. For fluorescence work, Richard Wolf lists PANOVIEW ULTRA telescopes optimised for ICG/NIR with the System green platform.

Plan spare capacity early. Because telescopes are the part most exposed to impact damage, many departments budget for periodic replacement and keep a rotation record so that the oldest telescope is retired before it affects image quality in the theatre.

Ordering and support

A department needs at least two telescopes per room, plus one spare per angle in the busiest theatres. Ask the supplier about repair turnaround, loan scopes and the warranty conditions for autoclave cycles.
