Rosonbot Files IPO Prospectus: Global Pioneer of Luosen Wanxiang® Intelligent Orthopedic Surgery Robot

Pelvic fractures are the most severe form of bone trauma, with mortality and disability rates ranking highest among all fracture types. The annual incidence of pelvic fractures in China is 700,000 cases; Type B and Type C fractures, which require surgical intervention, account for 81% of these cases, resulting in an estimated annual surgical volume of 567,000 procedures.As China accelerates its transition into an aging society, the incidence of fragility fractures of the pelvis (FFP) in the elderly has risen significantly, with the number of FFP cases projected to increase by 2.4-fold by 2030.

For orthopedic surgeons, pelvic fractures typically require open reduction and internal fixation in clinical practice. Such procedures are highly invasive, associated with slow healing, and prone to complications. This is particularly challenging in elderly patients, who often cannot tolerate open surgery. Meanwhile, manual closed reduction carries a high risk of iatrogenic secondary fractures. Consequently, these patients are frequently limited to conservative management, which results in significantly increased mortality rates.

Pelvic Fracture ReductionQuestionNot only is it a global challenge with extremely high surgical operational difficulty, but it also represents a typical unmet clinical need. Developed countries such as the United States, Japan, and Germany have conducted extensive research and development on “closed reduction of pelvic fractures,” yet no mature system has entered clinical application to date.

Through continuous efforts to overcome challenges,Rossum Wanxiang® Intelligent Orthopedic RobotIt can effectively compensate for the lack of reduction functionality in existing orthopedic surgical robots; it isGlobalThe First Surgical Navigation and Positioning System for Closed Reduction of Pelvic Fractures Using Robotic Technology. Compared with traditional surgery, it can reduce the risks of open surgery, shorten recovery time and hospital stay, while reducing radiation exposure doses for patients and medical staff. It can effectively improve the success rate of closed reduction surgery for pelvic fractures, especially fragile fractures in the elderly.

On Monday, January 15, at 19:30, the 42nd session of VCBeat Select New Product Showcase will feature Dr. Wang Yu, Chairman and CEO of Rossum Robot; Xu Qing, Chief Marketing Officer of Rossum Robot; and Zheng Xutao, Senior Marketing Director of Rossum Robot, who will present an introduction to the Luosen Wanxiang® Intelligent Orthopedic Robot.

By leveraging computer-aided automatic planning and intraoperative judgment by the lead surgeon, automated surgical planning for reduction and internal fixation has been achieved, thereby enhancing the intelligence level of orthopedic surgical robots.

By registering preoperative CT scans with intraoperative imaging, three-dimensional navigation for fracture surgery was achieved for the first time, comprehensively enhancing the precision and safety of fracture procedures.

Precisely implement the reduction planning results, calculate the reduction path, reduce the load requirements for reduction, and ensure a reduction operation error of <2 mm.

Non-invasive preoperative planning, millimeter-level intraoperative tracking error, millisecond-level tracking latency, and 3D modeling with CT slice reconstruction in any orientation.

Ensures safe reduction procedures through real-time monitoring of force and position data, with a maximum load capacity of 160 N.

Control the robotic arm to achieve active reduction, promoting the development of orthopedic surgical robots from static positioning to automated operation.
