According to the abstract released by the Intellectual Property India: "The present invention relates to an improved Boyle-Davis mouth gag assembly for otorhinolaryngological, oral, and maxillofacial surgical procedures. The assembly comprises an anatomically contoured frame with a ratchet-based clamping mechanism including a limit-stop feature to prevent excessive jaw extension, a detachable and adjustable tongue depressor, and removable soft padding for teeth and lip protection. The mouth gag is mounted on a Draffin bipod support system with height-adjustable rods and lockable swivel joints for stable, hands-free positioning. The components are fabricated using medical-grade polymers via additive manufacturing, enabling precise geometry, reduced weight, and modular assembly for sterilization and repeated use. The invention provides controlled mouth opening, improved patient safety, minimized tissue trauma, and enhanced surgical ergonomics, while supporting complex procedures and rapid prototyping of patient-specific designs."
