Surgical Contra-angles

For the highest surgical requirements

Surgical interventions represent a great challenge. To meet this challenge a number of surgical handpieces are required. W&H contra-angle handpieces made from high-quality stainless steel with special coating are particularly robust.

  • The new surgical contra-angle handpieces with mini LED+ and W&H connection


    Fatigue-free and flexible operation

    Optimum cooling and illumination of the treatment site. High-quality stainless steel with a scratch-resistant coating makes the contra-angle handpieces robust and gives them a particularly long service life.

    Surgical Contra-angle handpiece WS-75 L G

    Work with daylight quality

    As the undisputed leader in LED technology, W&H has developed surgical contra-angle handpieces with mini LED+, which offers outstanding illumination with high-contrast, natural light.

    Your advantages at a glance

    • Natural reproduction of red tones
    • Independent power supply with integrated generator
    • Longer life compared to conventional halogen bulbs
    • Fatigue-free working thanks to optimal ergonomics
    • Durable and robust due to high-quality stainless steel and scratch-resistant coating
    • Can be dismantled for thorough cleaning

    Fatigue-free working thanks to optimal ergonomics

    Fatigue-free working

    The ergonomic design is perfectly coordinated to all the application possibilities and prevents fatigue.
    Perfect light due to mini LED+

    Optimal illumination

    Thanks to its being half the size of a normal LED, the mini LED+ can be integrated very close to the contra-angle head and offers optimal illumination. With its neutral white light our LED provide a superior light source. This allows you to have daylight quality light in the treatment area regardless of whether you have an optic or non-optic drive system.
    Independent power supply

    Independent power supply

    As soon as you activate your contra-angle handpiece, the generator turns.

    It autonomously generates the electricity needed for the mini LED+ regardless of the type of drive system you work with.

    Scratch-resistant surface

    Scratch-resistant surface

    The unique coating protects the contra-angle handpieces from scratches. This facilitates cleaning and preserves the value.
    Can be dismantled without tools

    Perfect cleaning – Can be dismantled without tools

    To enable thorough cleaning to be carried out, the contra-angle handpieces can be easily and quickly dismantled and re-assembled – without the use of tools.

    Cleaning parts individually provides the most effective result.
    Variable cooling
