Official Achievement Announcement

Beyond the role of a mere pipe component supplier, we have built CoreLink, a system‑level application solution platform centered on high‑performance slotted rigid shafts. The platform delivers not only plug‑and‑play standardized tubular parts, but also one‑stop engineering services covering mechanical simulation support, polymer cladding composite processes, and integration with sensors/actuator units. We have empowered dozens of innovative medical device companies worldwide to integrate CoreLink core tubular components into their next‑generation rigid endoscopes, intelligent delivery robots and modular surgical platforms, shortening product development cycles by an average of 40% and significantly raising performance benchmarks for end‑use devices.

R&D Background & Pain Points

For many innovative medical device companies, especially start‑ups, developing a high‑performance rigid instrument body poses immense challenges. They must not only source reliable tubular suppliers, but also resolve a series of complex system integration issues: How to ensure firm bonding between the outer polymer layer (for insulation, biocompatibility or grip) and the inner metal tube without detachment or rotation? How to integrate sensor cables, drive wires or irrigation channels into the rigid shaft within extremely limited space while preserving its mechanical performance? How to verify the mechanical behaviour of the entire instrument system rather than individual components? These cross‑disciplinary problems spanning materials science, mechanical engineering and precision manufacturing become major barriers to translating brilliant ideas into reliable products. Many innovations are stalled at the prototype stage, or forced to adopt off‑the‑shelf solutions with compromised performance.

Core Technological Innovations

1. Composite Interface Technology with Enhanced Mechanical InterlockingWe deeply optimise slot patterns to serve as ultimate mechanical interlocking structures with polymer cladding layers. We have investigated the effects of different slot geometries (e.g., dumbbell‑shaped, dovetail, barbed) on polymer melt flow, penetration depth and final bonding strength, and established a dedicated database. Tailored to client‑selected polymer materials (e.g., PEBAX, Nylon), we recommend or customise optimised slot profiles, enabling tensile pull‑out strength of bonding interfaces to exceed that of the polymer itself and boosting torsional resistance by more than 5 times. Surface activation pre‑treatment is also provided to further enhance chemical bonding force.
2. Embedded Micro‑Channel & Cable Management Integration SolutionFor instruments requiring integrated wires, optical fibres or micro‑fluidic tubes, we offer pre‑integrated solutions. These include pre‑assembled biocompatible micro cable conduits or fluid channels inside or outside tube walls via laser welding or precision bonding. More advanced is our integrated skeleton design, which co‑optimises slot pattern layout with internal channel routing so that channels act as structural reinforcements instead of weakening elements. Precision lateral holes or windows can be fabricated at designated shaft positions for sensor protrusion or drug delivery.
3. System‑Level Mechanical Simulation & Testing Support PackageWe provide far‑reaching technical support beyond component drawings. Leveraging robust computational simulation capabilities, we conduct system‑level finite element analysis based on clients' overall instrument CAD models and intended clinical scenarios. We predict stress distribution at junctions between core tubular parts, handles and end‑effectors under combined loads, identify potential risks and propose improvement suggestions. During clients' R&D phases, we supply subsystem test samples and data incorporating our tubular components, greatly accelerating product validation and regulatory registration procedures.

Working Mechanism

The core value of the CoreLink platform lies in transforming slotted rigid shafts from passive components into active enabling platforms. Mechanically, it provides a validated, predictable mechanical performance foundation for the entire instrument, upon which all other functional modules are built as a stable chassis. Integration‑wise, its specially engineered surfaces and structures offer physical anchors and standard interfaces for various functional attachments. Information‑wise, it functions as a sensor carrier and cable pathway, serving as a high‑speed channel for data transmission.This platform‑oriented mindset frees instrument developers from ground‑up structural reliability work, allowing them to focus on proprietary clinical innovations such as unique end‑effectors, intelligent algorithms and novel power sources. Similar to developing applications on a robust chip, it drastically lowers innovation barriers and improves efficiency and success rates.

Performance Validation

Multiple successful cases demonstrate the value of the CoreLink platform.A European company developing an intelligent cutting instrument for otorhinolaryngology needed to integrate a cutting drill drive shaft, irrigation channel and 3D positioning optical fibre within a rigid sheath with only 3 mm outer diameter. We delivered a custom slotted shaft with embedded dual channels (one circular, one flat) and optimised slot patterns to maintain overall torsional rigidity post‑integration. The final product achieves high‑intensity cutting and precise navigation, with CE certification obtained.Another US robotic surgery firm required a compact yet ultra‑rigid proximal shaft for its laparoscopic instrument wrist to transmit massive clamping forces. We designed an ultra‑short, extra‑thick‑walled custom slotted shaft and resolved integration and sealing challenges with multiple drive wires, enabling the instrument to deliver 1.5 times the load capacity of competitors.Client feedback shows projects adopting our platform‑based solutions shorten the timeline from concept freeze to design validation by 6–9 months on average.

R&D Strategy & Philosophy

Our strategy is to be the innovator behind innovators. Positioned not merely as a custom‑manufacturing supplier working from client drawings, we act as a precision surgical structural platform provider and med‑tech translation accelerator. We proactively build early‑stage partnerships with university labs, research institutes and start‑ups, participating in conceptual design of cutting‑edge devices.Our philosophy holds that the greatest medical device innovations often originate from clinicians and cross‑domain engineers. Our mission is to translate their visionary concepts into solid, reliable and mass‑manufacturable products through our core expertise in precision structural and materials engineering. By building an open, flexible and supportive technical platform, we foster a vibrant innovation ecosystem and ultimately drive technological progress across minimally invasive surgery.

Future Outlook

In the future, slotted rigid shafts will play an increasingly prominent role as system cores and evolve into intelligent platform modules. We are developing standardised smart tubular modules pre‑integrated with multi‑axis force sensors, position sensors and micro‑connectors. Clients can plug‑and‑play these modules like building blocks to acquire powerful sensing and data processing capabilities.Meanwhile, we explore deep integration with micro‑actuators such as piezoelectric ceramics and shape‑memory alloy wires to develop semi‑active rigid shafts with local active bending or stiffness‑adjustable functions, blurring the boundary between rigid and flexible instruments.Our ultimate vision is to build an online collaborative design platform, where global device developers can configure, simulate and order customised pre‑integrated core structural units in the cloud just like selecting functional modules in an app store, bringing high‑end custom medical device development into a new era of democratised high‑speed innovation.
