The Mayo-Hegar Needle Holder, 12 cm (or 12.5 cm depending on the manufacturer) is a highly compact, specialized hemostatic-style needle driver designed for driving intermediate-to-heavy suture needles in confined operating fields. While the standard 14 cm and 15 cm versions are used for general tissue layers, this shorter 12 cm variant is explicitly favored in dentistry, oral surgery, veterinary medicine, and minor superficial dermatology procedures where space is highly limited.
