Slotted Rigid
Technical Specifications
| Material | High-tensile Medical-grade Stainless Steel (304, 304V, 316L) preferred for maximum stiffness and structural integrity. |
|---|---|
| Tolerance | Outer Diameter (OD) strict tolerances up to ±0.01 mm. Precisely controlled staggered kerf widths to maintain shaft rigidity. |
| Surface Treatment | Electropolished, passivated, and completely burr-free inside and out, ensuring smooth integration with polymer jackets or internal stylets. |
| Outer Diameter (OD) | Custom-manufactured from micro Ø 1.0 mm to Ø 15.0+ mm based on your specific rigid shaft requirements. |
| Wall Thickness | Customizable wall thicknesses designed to balance internal lumen capacity with ultimate radial crush resistance. |
Engineering & Application Overview
The Slotted Rigid Hypotube is the definitive structural core for medical devices that require uncompromising straight-line navigation. Unlike solid un-cut tubing which may catastrophically crease under lateral stress, the micro-slotted rigid shaft absorbs and distributes high-stress loads, preventing sudden failure while maintaining absolute directional control.
Advanced Fiber Laser Micro-cutting utilizing Staggered or Interrupted Slot Patterns. This allows our engineers to leave substantial uncut metal bridges, ensuring the shaft remains unbending while gaining vital anti-kink properties and surface texturing for polymer overmolding.
• Maximum Pushability: Delivers superior axial column strength for driving instruments through dense tissues or tight strictures.
• Anti-Buckling / Strain Relief: Staggered slots prevent the rigid tube from catastrophic kinking under unexpected loads.
• Enhanced Overmolding: The laser-cut gaps provide excellent mechanical interlocking points for outer polymer jackets.
Rigid Endoscope Shafts (Laparoscopes, Arthroscopes), Stiff Delivery Catheters, Trocar Cannulas, Biopsy Needles, and heavy-duty Orthopedic Guides.
Manufactured under strict ISO 13485 protocols. Shafts are subjected to rigorous axial compression and torsional testing to ensure they will not yield during critical surgical procedures.
