Medical Grade Spring

Core Product Categories

  • · Medical Compression Springs

    o Micro-precision compression springs designed for axial load applications, available in extremely small wire diameters and compact dimensions.

    o Key features: tight force tolerance, consistent performance across sterilization cycles, burr-free and smooth surface finish.

    o Typical applications: syringes, insulin pens, surgical staplers, infusion pump valves, dental handpieces, diagnostic test cartridges.

  • · Medical Torsion Springs

    o Custom torsion components with precision torque arms, delivering accurate rotational restoring force through torsional and bending deformation.

    o Key features: smooth actuation, precise torque output, high cycle fatigue resistance for repeated opening/closing operations.

    o Typical applications: surgical forceps, needle holders, laparoscopic graspers, endoscopic instruments, surgical robot joints.

  • · Medical Extension Springs

    o Tensile springs with precision-formed hooks or loops, providing uniform tensile force for retraction and traction functions.

    o Key features: high pull-out strength, minimal force drift over service life, secure end configurations for reliable assembly.

    o Typical applications: tissue retractors, suture delivery systems, orthopedic traction devices, cable retraction in surgical robots.

  • · Medical Wave Springs

    o Ultra-low-profile flat wire wave springs optimized for space-constrained medical assemblies.

    o Key features: reduced axial height by up to 50% vs. standard coil springs, lightweight, uniform load distribution.

    o Typical applications: bearing preload in surgical motors, seal compression in implantable pumps, endoscopic camera assemblies, miniature valve actuation.

  • · Catheter & Guidewire Springs

    o Ultra-fine helical springs manufactured from micron-level wire, designed for interventional and endoscopic use.

    o Key features: excellent flexibility with kink resistance, ultra-smooth outer surface, radiopaque material options for imaging visibility.

    o Typical applications: vascular catheters, guidewires, endoscope shafts, minimally invasive surgical tools, cardiac electrophysiology devices.

  • · Medical Constant Force Springs

    o Flat strip springs that deliver uniform force over a long linear stroke.

    o Key features: consistent force output, smooth linear motion, high cycle life for continuous operation.

    o Typical applications: infusion pump drives, retractable syringes, surgical instrument counterbalance systems, automated drug delivery devices.
