MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202641072887 A) filed by Saveetha Institute Of Medical And Technical Sciences on June 12, 2026, for A Modular Self-Retaining Dual-Arm Retractor With High-Friction Buccal Interface And Soft Lingual Retraction Component For Mandibular Third Molar Surgery.
Inventors include Vishal Ramachandran; and Deepak Nallaswamy Veeraiyan.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The increasing demand for precision, efficiency, and atraumatic tissue handling in oral and maxillofacial surgery has highlighted the limitations of conventional retractors, which rely on continuous manual assistance, exhibit poor stability on the buccal bone surface, and may contribute to soft tissue injury and operator fatigue. The present invention introduces a modular self-retaining dual-arm retractor designed to provide stable, hands-free retraction of both the buccal flap and the tongue during mandibular third molar surgery. The device comprises a central handle incorporating a ratchet-based locking mechanism that enables incremental adjustment and secure retention of retraction forces without continuous manual support. The buccal retraction arm is provided with a high-friction interface, preferably enhanced by plasma coating, to ensure firm engagement with the buccal bone and prevent slippage. The lingual retraction arm incorporates a detachable soft-tissue interface configured to safely accommodate and retract the tongue while minimizing pressure-induced trauma and discomfort. The modular configuration allows adaptability to varying anatomical conditions and surgical requirements. By integrating controlled self-retention, enhanced grip, and soft-tissue protection within a single device, the invention improves surgical visibility, reduces operative time, minimizes tissue injury, and enhances overall procedural efficiency and clinical outcomes.
