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

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

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

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

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

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

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

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
