Application Case

1.2 Follicle Extraction Punches

Key Specifications & Customization

• Materials:
  • Medical-grade 316L stainless steel (standard) or fine-grain tungsten carbide (high-wear needs)—both ISO 10993-5 compliant (cytotoxicity-free).
• Design Customization:
  • Inner Bore Diameter: 0.6mm–1.2mm (matched to follicle size: 0.6mm for fine hair, 1.2mm for thick/curly hair)—tolerance IT4 (±0.001mm) to ensure consistent follicle fit.
  • Bore Profile: Tapered (1°–2° internal taper) for smooth follicle removal, or straight (for rigid scalp areas)—inner surface polished to Ra ≤0.02μm to protect follicle roots.
  • Length: 10mm–20mm (optimized for different scalp thicknesses: 10mm for thin scalps, 20mm for thick/cushioned scalps).
• Clinical Advantage:
  
  
  Our punches enable 98%+ follicle survival rates by minimizing mechanical trauma—critical for patient satisfaction and repeat business.

1.3 Hair Implantation Needles

Key Specifications & Customization

• Tip Design: Blunt-tipped (prevents follicle cutting) or semi-sharp (for dense scalp tissue)—customizable bevel angle (15°–30°).
• Dimensions: Outer diameter 0.8mm–1.4mm, length 12mm–25mm—compatible with manual implantation forceps or automated tools.
• Material: Medical-grade 316L stainless steel with passivation treatment—enhances corrosion resistance and biocompatibility.

2. Custom Skin Biopsy Devices

2.1 Skin Biopsy Punches

Key Specifications & Customization

• Materials:
  • Medical-grade 316L stainless steel (standard) or tungsten carbide (for high-volume clinics)—both offer excellent edge retention and resistance to skin acids.
• Design Customization:
  • Diameter: 1mm–8mm (1mm–3mm for small lesions, 4mm–8mm for larger/malignant-suspect lesions)—tolerance IT5 (±0.002mm) for consistent sample size.
  • Depth Control: Fixed-depth (2mm–6mm) or adjustable-depth (via collar) designs—prevents over-penetration into subcutaneous tissue.
  • Handle: Ergonomic knurled grip (diameter 8mm–12mm) for non-slip control—critical for precise placement on curved skin surfaces (face, limbs).
• Clinical Performance:
  • Cutting Edge: Razor-sharp (edge radius ≤0.005mm) for clean tissue separation—reduces sample fragmentation and improves diagnostic accuracy.
  • Sterilization: Autoclavable (134°C) and compatible with EO/gamma radiation—no rust or edge dulling after 50+ cycles.

2.2 Skin Biopsy Forceps & Sampling Needles

Key Specifications & Customization

• Biopsy Forceps:
  • Jaw Design: Serrated (for secure tissue grip) or smooth (for delicate skin)—jaw size 2mm–10mm (customizable for lesion size).
  • Material: Medical-grade 316L stainless steel with spring-loaded mechanism—ensures consistent jaw pressure and reduces hand fatigue.
• Core Biopsy Needles:
  • Gauge: 18G–25G (18G for deep tissue, 25G for superficial lesions)—length 5mm–15mm.
  • Tip Design: Franseen (for soft tissue) or Tru-Cut (for firm lesions)—customizable to your clinic’s biopsy protocol.

3. Our “Drawing-Based Customization” Process

Step 1: Drawing Submission & Clinical Consultation

• Share your 2D/3D drawings or clinical requirements (e.g., “FUE punch compatible with Artas 9x machine,” “4mm biopsy punch with 3mm depth stop”).
• Our engineering team reviews:
  • Compatibility with your existing instruments (e.g., handle diameter, connection type).
  • Clinical feasibility (e.g., minimum needle gauge for pediatric use, blade thickness for sensitive scalp).
• Deliver a technical quote + DFM (Design for Manufacturability) report within 24 hours.

Step 2: Prototype Development

• Produce 1–5 prototypes using precision CNC machining (for steel components) or diamond grinding (for tungsten carbide parts).
• Inspect prototypes with:
  • CMM (accuracy ±0.0005mm) for dimensional compliance.
  • Optical profilometer for surface roughness (Ra) testing.
  • Biocompatibility pre-testing (ISO 10993-5) for medical-grade materials.
• Ship prototypes + inspection reports for your clinical validation (5–7 days lead time).

Step 3: Mass Production & Quality Control

• Scale up with automated machining lines—ensure batch consistency (tolerance variation ≤0.002mm).
• 100% inspection for critical features:
  • Blade edge sharpness (laser edge tester).
  • Biopsy punch depth accuracy (calibrated gauges).
  • Sterilization validation (ISO 11135 for EO, ISO 11134 for autoclaving).

Step 4: Delivery & After-Sales Support

• Packaging: Sterile blister packs (ISO 11607 compliant) with batch/lot numbering for traceability.
• Documentation: CoC (Certificate of Conformance), MTR (Material Test Report), and sterilization validation certificates.
• Warranty: 12-month warranty—free replacement if devices fail due to manufacturing defects; technical support for instrument integration.

4. Quality Assurance & Compliance

• Certifications: ISO 13485 (medical device quality management), FDA 21 CFR 820, CE MDR (Class I/II medical devices).
• Material Compliance: Medical-grade 316L stainless steel (ASTM F138), tungsten carbide (ISO 3325)—both ISO 10993-5/-10 compliant (no cytotoxicity/irritation).
• Testing: Routine tests include corrosion resistance (ASTM B117 salt spray), sharpness retention, and sterilization durability.
