Medical Instrument Tweezers Tip

Medical Instrument Tweezers Tip surfaces undergo multiple-stage cleaning and passivation processes to eliminate leachable ions, residues, or inclusions that may compromise patient safety. All substrate materials are certified per ISO 10993-1 for cytotoxicity, sensitization, and irritation resistance. Post-machining decontamination is carried out using ultrasonic aqueous cleaning with enzymatic surfactants followed by Class 100 laminar flow drying. Material traceability down to melt lot and certification number is maintained for every tweezers tip delivered, ensuring conformance with MDR and FDA 21 CFR Part 820 requirements for invasive surgical devices. 

Medical Instrument Tweezers Tip surfaces are finished to Ra ≤ 0.15 µm using ion-polishing and fine abrasive flow machining techniques. This ensures smooth tactile engagement with tissue or micro-components while preventing particulate generation or edge flaking during use. Contact zones are designed with controlled roughness gradients to deliver high friction coefficients without introducing tissue indentation. Surface mapping using 3D profilometers confirms uniform texture and absence of microburrs, critical for cleanroom compatibility and Class III surgical applications.
