The Schuknecht Weitlaner Retractor (130mm Length, 3x3 Sharp Prongs) is a surgical instrument used in otologic procedures for retraction of tissues. It features 3 sharp prongs on each side, which are designed to provide a firm grip on tissue while maintaining minimal trauma during retraction. The 130mm length offers a good balance between reach and precision, making it ideal for middle ear and other delicate surgeries that require clear access to deeper structures.
