Wellcare Medical Systems

An arthroscopy trocar set includes a cannula (sheath), trocar (obturator), often 3-in-1, made of stainless steel, designed for compatibility with specific arthroscopes (e.g., 4mm x 175mm, 30°), featuring ergonomic design, high-flow valves, and varying tip types (conical/fenestrated) for precise joint access and instrument passage during minimally invasive joint procedures. Specifications focus on material, dimensions (diameter, length), scope compatibility, flow rates, and sterilization compatibility for different joint applications like knee or shoulder. Key Specifications & Components:

• Components: Typically a 3-in-1 set: Cannula (sheath), Trocar (conical obturator), and sometimes a switching stick/rod.
• Material: High-quality Stainless Steel (for durability and sterilization) with medical-grade plastics.
• Compatibility: Matched to specific arthroscopes (e.g., 4mm diameter, 30° angle, 175mm length).
• Cannula Features:
  • Flow: High-flow, double-valve systems for better joint distension.
  • Tip: Fenestrated (slotted) or blunt for controlled insertion.
  • Design: Fully rotatable, J-lock fixation for secure scope attachment.
• Trocar Features: Conical tip for easy tissue penetration, blunt for soft tissue protection.
• Sizes: Vary by joint; common for knee: 4mm diameter, 175mm length; wrist: 2.7mm scope with 4.0mm trocar.
• Sterilization: Autoclavable or pre-sterilized, ready for use. 

Typical Set Inclusions:

• Diagnostic Cannula (e.g., 3-4mm, high flow)
• Conical Trocar (matching cannula size)
• Possibly a switching stick/rod
• Sterilization tray/container 

Factors Influencing Choice:

• Joint: Knee, shoulder, wrist, elbow require different sizes/configurations.
• Flow Needs: High flow for distension, standard for others.
