For extensive exposure in deep or superficial surgical sites, such as in soft tissue, spinal, and orthopedic procedures, a self-retaining retractor is used. This 8" Weitlaner retractor is made of surgical-grade stainless steel for durability, corrosion resistance, and repeated sterilization. It has hinged arms for adjustable positioning and four sharp prongs on each side for a secure grip on tissue. The ratcheted locking mechanism maintains constant tension for hands-free operation.
