Vascular suturing device needle caps | Thin-wall micro-sleeve machining

Material: SUS304 / SUS316 medical-grade stainless steel
Process: laser micro-cutting combined with micro-turning, with full-process control to meet medical device cleanliness requirements and high-precision assembly specifications.
Solution: thin-wall micro-sleeves and needle caps for vascular suturing devices, with close control of bore accuracy, concentricity, burrs, and cleanliness.
Result: improved assembly stability and smoother operation, compatible with a range of medical sterilization conditions.

Endoscope articulation joint rivets | Precision riveting

Material: 316L medical-grade stainless steel
Requirements: tight dimensional accuracy and coaxiality, low roughness, burr-free surfaces, clean passivation, fatigue resistance, and suitability for medical sterilization.
Solution: control incoming material, riveting, fatigue validation, and cleaning throughout production to address loosening, jamming, wear debris, and corrosion under disposable and reusable endoscope bending and sterilization conditions.
Result: articulation pivot pins with smooth rotation, consistent backlash, secure fatigue-resistant joints, and corrosion and sterilization resistance, improving steering feel and clinical safety.

Disposable bidirectional bending section | Endoscope distal steering assembly

Material: SUS304 / SUS316L / Nitinol
Requirements: precision symmetric assembly of medical-grade materials for smooth, jam-free bidirectional steering, with strict dimensional, surface, and cleanliness control to meet single-use mechanical and biocompatibility requirements.
Solution: symmetric construction and tension-controlled assembly enable independent steering in both directions, with a radiopaque tip and medical sheath. Single-use construction avoids cross-infection.
Result: precise bidirectional steering for lesion visualization and smooth control, with a radiopaque tip and single-use design for minimally invasive endoscopy across specialties.

Gradient-slotted hypotube | Endoscope torque and push transmission

Material: SUS304 / 316L / Nitinol
Requirements: precision laser-cut gradient slots without burrs or cracks, balancing pushability, torque transmission, and kink resistance. Smooth articulation-joint interfaces, dimensions, and cleanliness support disposable endoscope channel access.
Solution: gradient slotting provides segmented stiffness for stable push and torque transfer with kink resistance. A smooth interface with the bidirectional bending section supports advancement and steering in disposable minimally invasive endoscopes.
Result: combines proximal pushability with distal flexibility and controlled torque to improve instrument passage through channels.

Beryllium copper probes | Semiconductor, FPC, and medical electronics micro-contact testing

Material: beryllium copper alloy
Requirements: precision micro-turning, residual stress and beryllium dust control, inert-gas aging, and clean electroplating for stable elasticity and low contact resistance.
Solution: low-damage, elastically stable contact solutions for medium- and high-frequency micro-contact testing of semiconductors, FPCs, and medical electronics.
Result: controlled light contact force and stable elasticity reduce soft-pad damage. Low, consistent resistance supports medium- and high-frequency signals, production test yields, and hundreds of thousands of test cycles.

Bending assembly solution for gastrointestinal endoscopes

Material: 304 stainless steel
Requirements: highly flexible repeated bending, zero play, long fatigue life, and precise bending at multiple angles
Solution: customize the riveted articulation structure and combine precision laser cutting with micro-deformation rotary riveting. Closely control gap uniformity and micro-burrs to reduce bending stress.
Result: smooth steering and rotation of the endoscope bending section with lasting stability, meeting the demands of frequent bending in clinical use.

Camera retaining spring assembly solution

Material: phosphor bronze / 304 stainless steel
Requirements: miniature irregularly shaped springs, constant clamping force, assembly in tight spaces, and resistance to deformation
Solution: fine laser cutting, forming and bending, stress relief, and tight control of springback tolerances
Result: secure clamping and effective vibration damping maintain stable endoscope camera assembly and prevent image shift
