About

Robotic assisted surgery has been performed for more than two decades with good success and safety profile. However, there was only one dominating robotic surgical system available in the past which led to high cost for robotic surgery. Recently, a new robotic surgical system (Sentire Robotic Surgical System) was introduced by researchers of The Chinese University of Hong Kong (CUHK). This new robotic surgical system aims to achieve similar outcomes and standards of robotic surgery performed using the dominating system but with a significantly lower cost. The technologic innovation and development of this new robotic system is made by the Cornerstone Robotics Limited, which is based in Hong Kong. In a pilot clinical study conducted at Prince of Wales Hospital involving 55 patients, the Sentire Robotic Surgical System had demonstrated high success rate with minimal complications in patients who underwent robotic colorectal, upper gastrointestinal, and urologic surgery. Researchers of CUHK would therefore like to conduct another prospective study to further evaluate the efficacy and safety of Sentire Surgical System C1000 in major gastrointestinal and urologic surgery with expanded indications. It is believed that the results of this study will provide data to support its use for wide range of procedures with minimal access trauma, for the benefit of patients. This system will also lead to a wider range of clinical application for minimally invasive surgery with a cost-effective model.
