Longwell Medical's TRex®-RS Robotic System for Total Hip Arthroplasty: A Surgeon’s Trusted Assistant

VCBeat Selects New Products Review, Issue 7, featuringZhang Haining, Deputy Dean of the Orthopedic Hospital Affiliated to Qingdao University, and Dai Xiangdong, General Manager of Longhui MedicalBringing you an in-depth interpretation of Longhui Medical’s TRex®-RS Joint Replacement Surgical Robot.

1. Innovative Overall Design

Two-part design eliminates the need for a separate console, allowing surgeons to directly control the robotic arms; wireless connectivity simplifies surgical room layout and reduces turnover time; proprietary technology removes the need for robotic arm trackers, enabling surgeons to maintain their standard intraoperative positioning habits.

2. Six-Degree-of-Freedom Manipulation and Real-Time Six-Degree-of-Freedom Tracking of the Robotic Arm

When intraoperative bone displacement occurs, the entire robotic system tracks the movement like a missile, achieving real-time dynamic precision during surgery; this makes robot-assisted total hip arthroplasty (THA) feasible for the entire procedure (femoral side + acetabular side); it eliminates system crashes caused by bone movement, ensuring smooth surgical workflows and improving operational efficiency.

3. Unique algorithm, faster and more accurate, with broader applications

Real-time verification, free selection of landmarks; surgical scope expanded from standard hip procedures to complex hip cases, and surgical approaches broadened from the posterolateral approach to include multiple techniques such as the direct anterior approach (DAA).

To provide a more comprehensive understanding, the Longhui Medical TRex®-RS Joint Replacement Surgical Robot will be launched on VCBeat Select New Product Launch on Thursday, April 20, 2023, from 19:30 to 20:30.
