News - Medical‑Engineering Integration Drives R&D Innovation｜On‑site Report on Chenanhui Technology Orthopedic Power Tool Development

Recently, in the R&D laboratory of Sichuan Chenanhui Technology, a joint seminar featuring medical-engineering integrated R&D was underway. Orthopedic clinical experts, together with in-house engineers for mechanical structure, motor electronic control and material testing, gathered at the development site. Focusing on new-generation brushless orthopedic surgical power tools, the team conducted prototype testing, problem review and solution iteration. It forms a complete innovation chain of “clinical demand-engineering design-prototype verification-process optimization”. Deep medical-engineering integration accelerates the upgrade and iteration of domestic orthopedic surgical equipment.

Orthopedic power tools are core equipment widely applied in trauma, joint, microsurgery and neurosurgical operations. Drawing on abundant practical surgical experience, clinical experts raised real-world clinical pain points at the site, including torque stability of high-speed cannulated drills, operator fatigue from long-time handheld manipulation, equipment reliability after repeated high-temperature and high-pressure sterilization, speed-torque matching for various surgical conditions, and chuck clamping precision. The engineering team recorded clinical feedback on-site, analyzed every issue against actual prototype test data. Discussions covered brushless motor calibration, complete-unit sealing structure, ergonomic handle design, transmission assemblies and battery power management, ensuring every orthopedic power tool meets real surgical demands. The team translated these real-world requirements into implementable technical indicators.

At the R&D workshop, the technical team carried out simulated-condition tests for multiple orthopedic power tool prototypes: high-speed cannulated drill, oscillating saw, reciprocating saw, micro bone drill and multi-functional power host. Targeting common clinical scenarios such as osteoporosis and complex comminuted fractures, key parameters of these orthopedic power tools, including output torque, speed range, radial run-out, host temperature rise and noise, were verified repeatedly.

“Medical device innovation cannot be limited to theoretical parameters. It has to fit surgeons’ actual hand-on experience with orthopedic power tools in surgery”, commented the R&D lead. Every prototype generation goes through multiple cycles of medical-engineering interaction. Clinicians give feedback on operation performance, engineers revise structural design, followed by new sample production and re-testing. Such iterative cycles maximize product adaption to real clinical habits.

Conventional medical device R&D often faces disconnection between technical design and clinical reality. Engineers design products based on theory, which may not fit real operating-room scenarios. Following the development principle of “clinical requirements put forward problems, engineering provides solutions”, Chenanhui Technology brings clinicians into front-line R&D on a regular basis. Physicians participate throughout product definition, solution review and prototype validation. Taking clinical pain points as the starting point of development, the company breaks the old path of “finish product first then adapt to clinics”. It mitigates potential functional shortcomings after product launch and improves the practicality and safety of domestic orthopedic power tools from the source.

At material and reliability testing station, R&D personnel performed durability validation for orthopedic power tools, titanium alloy parts, sealing components and battery packs. Hospital-grade repeated 134℃ high-temperature high-pressure sterilization environment was simulated to assess long-term stability of full equipment. All procedures are well-connected: motor performance simulation, 3D structural design, prototype manufacturing, biomechanical simulation and on-site evaluation by clinical specialists, speeding up transformation from technical research to market-ready medical devices.

Domestic high-end orthopedic surgical equipment is achieving rapid localization in China, and medical-engineering collaboration has become a vital innovation driver for medical devices. Moving forward, Sichuan Chenanhui Technology will continuously strengthen joint innovation with medical institutions. Centered on unmet clinical needs in trauma orthopedics, microsurgery and neurosurgery, the company will keep optimizing brushless orthopedic power tools and matching implant products. It will develop reliable, cost-effective domestic medical devices, delivering high-quality China-made solutions for hospitals home and overseas. The enterprise supports the Healthy China Initiative and promotes Chinese orthopedic medical devices onto the global market.
