Williger Elevator

Description

The Williger Elevator is a surgical instrument used in orthopedic surgeries, namely bone harvesting, repair, and contouring. Here are some relevant details about it:

Purpose: It serves to separate the periosteum, a strong membrane that protects the bone, from the underlying bone surface. This permits surgeons to reach and operate directly on the bone.

Design:

• It has a flat, robust handle with horizontal ridges for a firm grip and less hand strain.
• The working end has two basic variations:
• Round cutting edge: This sensitive tip reduces stress to surrounding tissue and is available in sizes appropriate for both infants (4.0mm) and adults (7.0mm).
• Raspatory: Single-sided, curved, with a working end of 55 x 4.0mm, also available in 6.0mm width.
  Benefits:
• Allows doctors easier access to bone during surgery.
• The delicate design minimizes injury to neighboring tissues.
• Available in a variety of tip sizes to suit different bone shapes.
• The ergonomic handle provides improved control and avoids hand strain.
