1. The 22.5Fr / 21Fr Architecture

Reducing an instrument’s diameter usually comes at the cost of fluid flow. However, the LRS105C overcomes this through precision engineering.

Outer Sheath (S2218-5C): At just 22.5Fr, it is nearly 4Fr smaller than a standard resectoscope. This dramatic reduction transforms the ease of insertion.

Inner Sheath (S2120-5C): At 21Fr, it tightly houses the working element while preserving a dedicated inflow channel.

The gap between the 22.5Fr outer and 21Fr inner sheaths is calibrated to microscopic tolerances to ensure that despite the small size, a Continuous Flow of saline is maintained to cool the laser fiber and clear the visual field of blood.

2. The 2.9mm Visual System

The heart of the LRS105C’s slim profile is its optical core. It utilizes the 9302.30 Endoscope, which has a diameter of only 2.9mm (compared to the standard 4mm).

Despite the reduced diameter, this telescope utilizes high-density rod-lens technology to deliver a Full HD Image with a 30-degree field of view. This ensures that “going small” does not mean “going dark.” Surgeons retain the crystal-clear visualization needed to identify delicate landmarks like the ureteral orifices in a small pediatric bladder.

3. Titanium Alloy Precision (W5012P)

In a miniaturized system, the working element must be both lightweight and incredibly rigid to prevent bending. The LRS105C offers the W5012P Working Element, crafted from Titanium Alloy.

Heat Resistance: In the confined space of a 21Fr sheath, the laser fiber is closer to the metal walls. Titanium’s superior thermal properties prevent the tip from overheating during high-energy lasing.

Durability: Titanium provides the structural integrity needed to ensure the thin guide tubes do not warp, guaranteeing smooth instrument action year after year.
