High-performance implants and orthopedic systems manufactured to strict CE and ISO standards, guaranteeing safety and exceptional surgical outcomes.
Endobuttons represent a critical evolution in sports medicine and reconstructive orthopedics, particularly for Anterior Cruciate Ligament (ACL) and Posterior Cruciate Ligament (PCL) reconstructions. As key components in suspensory cortical fixation, these tiny, precision-engineered titanium buttons bear massive, cyclic physiological loads. A high-quality Endobutton must offer optimal tensile strength, minimal displacement, and complete bio-inertness to ensure rapid patient rehabilitation and permanent graft security.
At Changsha WEX Medical Instruments Co., Ltd., our production strategies are built on more than two decades of research, development, and validation alongside global orthopedic surgeons. We deliver CE-certified solutions designed to mitigate the risks of loop stretching, bone tunnel widening, and graft slippage.
By leveraging biocompatible Grade 5 Titanium (Ti-6Al-4V) and advanced loop fibers, our fixation technologies ensure a predictable mechanical grip. This provides surgeons with maximum tactile feedback during deployment and guarantees stability across the femoral cortex.
Exploring the engineering and regulatory paradigm shifts defining modern reconstructive surgery.
Modern sports medicine focuses on limiting microscopic graft movement within the bone tunnel. Next-generation Endobuttons utilize continuous loop technologies (using ultra-high-molecular-weight polyethylene - UHMWPE) to minimize construct elongation. This drastically reduces the risk of the "windshield wiper" effect, allowing for rapid integration of the soft tissue graft into the host bone.
Navigating international regulatory frameworks requires complete traceability. Following the transition from the Medical Device Directive (MDD) to the more rigorous Medical Device Regulation (MDR 2017/745) in Europe, medical device exporters must present extensive clinical data. WEX Medical ensures all raw materials are traceable and that our implant systems undergo extensive biocompatibility validations.
The industry's technical roadmap points toward bioactive interfaces. While titanium remains the standard for cortical fixation due to its superior strength, graft-stabilizing interference screws are shifting toward Peek and composite bioabsorbable materials (like PLDLA and hydroxyapatite). This clinical pathway stimulates bone-remodeling processes and reduces the need for secondary hardware removal.
Detailed look at our state-of-the-art production environments and testing workflows, aligned with GMP standards.
Original Corporate Statement: Changsha WEX Medical Instruments Co., Ltd. has experiences of more than two decades in areas of innovation and production of orthopaedic implants, such as bone plates, bone screws, interlocking nails, spine implants/internal fixation systems, and all kinds of instruments, which are branded by "WEX". All the implant products have certification of CE and ISO9001/ISO13485, so can reach different requirements of customers.
With a Quality Management System passed ISO 9001:2008 and ISO 13485:2003, we have bright and spacious factory workshops; more than hundred production equipments, such as advanced CNC machining centre machines, CNC sliding headstock auto-lathes, CNC milling machines, CNC lathing machines, upmarket ultrasonic cleaning equipments and etc; more than ten advanced and well-appointed testing equipment, such as Projectors, Tensile-testing machines, Durometers, Carbon and sulphur analyzers, Pitting LP detecting instruments and Fluorescent fault detectors and so on. The packaging process is conducted in clean workshop line with GMP standard.
At the beginning of company's establishment, we aim to design and produce implantable products professionally for our customers. Relying on the operational systems of development, design, production and marketing, which is formed by the orthopaedic experts in domestic large and medium-sized hospitals, also we completed the clinical insurance for our products. We satisfy our customer's requirements with best quality and best service, based on our advanced production and processing technology. Because we insist on the idea of "Be professional for manufacturing high-quality products, be wholehearted for serving customers."
How WEX Medical is driving next-generation orthopedic fixation technologies.
Developing radiolucent implants that reduce CT/MRI artifacts. Our engineering team is currently testing medical-grade carbon-fiber reinforced PEEK structures to achieve elastic modulus levels that closely mimic human bone.
Implementing titanium plasma sprays and hydroxyapatite coatings on ligament-to-bone contact points. This modification speeds up osseointegration and reduces the recovery time for athletes post-reconstruction.
Utilizing 3D-printing technologies to customize bone plates, spinal cages, and fixation structures for complex trauma revisions and pediatric applications.
Long-term R&D targeting micro-sensors embedded in external fixators and intramedullary structures to feed real-time strain and recovery data back to orthopedic teams.
How WEX integrates trauma, spine, and sports medicine implant systems for global distribution.
Our trauma portfolio includes elastic intramedullary nail sets, retrograde tibial nails, maxillofacial locking plates, and double-head retractors. Designed for ease of use in fast-paced emergency settings, these tools provide surgeons with reliable, sterile solutions.
Featuring lumbar PEEK cages, pedicle screw systems, crosslink connectors, and anterior cervical plate constructs. WEX spinal implants are designed to restore physiological lordosis, promote spinal fusion, and maintain spinal alignment across all age groups.
By pairing suspensory Endobutton systems with high-quality cannulated interference screws and specialized arthroscopic instrumentation kits, WEX provides healthcare organizations with complete, reliable systems for ACL/PCL reconstruction.
Essential technical and regulatory information for clinical directors, hospital buyers, and global distributors.
