The McCollum Dingman Submammary Dissector by Stellmacher is a precision surgical instrument designed for controlled tissue separation during breast augmentation and reconstructive procedures. Featuring a 30 cm length with an offset bayonet shaft, it allows improved access and visibility when the incision site is positioned away from the area being dissected.

The oval spatulated blade is structured to support blunt dissection and careful development of tissue planes within the submammary space and surrounding anatomical areas. Its angled shaft configuration enhances maneuverability during transaxillary and related surgical approaches.

Manufactured from high-quality stainless steel, this instrument provides durability, corrosion resistance, and compatibility with standard sterilization methods. Built to Stellmacher quality standards, it is intended for repeated professional use in clinical environments requiring precision and reliability.
