What MEDLANE knows about the instrument
Recognising architectures, materials, control protocols, marking and traceability, inspection: five documented axes, each linked to its source. Nothing here is published as a contractual specification or as current proof of conformity.
MEDLANE Instrument Atlas
An atlas of recognition: complete silhouettes, jaw macros, architecture comparisons, eponyms and verified quizzes, all built on real MEDLANE references and their catalogue photographs.

Role of the alloying elements
- Carbon determines hardness, chromium corrosion resistance.
- Molybdenum and vanadium are optional elements adding cutting-edge longevity and impact resistance respectively.

Quality Lab — how an instrument is controlled
MEDLANE documented protocols, described here for their educational value. They do not constitute the release criteria in force.
The five control families
- Rockwell hardness testing.
- Visual and functional inspection.
- Mechanical testing.
- Cutting performance testing.
- Corrosion-resistance testing.

Quality system in force
- MEDLANE's quality management system is certified to ISO 13485:2016 by IMQ (certificate 0270.2026) for the design, production management and distribution of operating-room surgical instrumentation and sterilization containers.

Elasticity test
- 01The instrument is closed to the last ratchet tooth and held under load for 3 hours at room temperature.
- 02After the corrosion test, the instrument is inspected for cracks and permanent deformation.
MEDLANE documentation · Dossier technique instrumentation MEDLANE — version 21 · 2021-12
Gripping function test
- 01A plastic thread or suture of diameter 0.2 mm or less is placed in the active part, then the instrument is closed.
- 02A 20 N pull is applied: the thread must not escape under either longitudinal or transverse load.
MEDLANE documentation · Dossier technique instrumentation MEDLANE — version 21 · 2021-12
Cutting test
- 01The test material is selected according to the instrument category; Mayo and Metzenbaum scissors appear in the “medium, ring-handled” category of the documented table.
- 02Cutting is performed over two thirds of the blade, three times, without lateral pressure.
- 03The expected cut is clean, with no tearing of the test material.
MEDLANE documentation · Dossier technique instrumentation MEDLANE — version 21 · 2021-12
Corrosion test
- 01A cleaning cycle is applied to the instrument before testing.
- 02The instrument is immersed in demineralised water at 90 °C for 1 hour, then air-dried.
- 03Visual inspection looks for rust marks, micro-cracks and other surface defects.

MEDLANE catalogue reference
- 02
Laser marking
Thermal annealing, no material removal
- 03
Data Matrix ECC200
Date, time and serial-number variables
- 04
Identification
Logos and barcodes supported
- 05
Hospital scanning
Barcode-reader, PLC or RS232 input

Reprocessing traceability
Histories generated at the marking station
In-house laser marking
- Instrument marking is performed in-house by laser, using a thermal annealing process that marks without removing material.
- The installation described in the process documentation is a YAG TD412 laser: 254 mm focal length, 180 × 180 mm marking field, motorised Z axis, dedicated enclosure accepting up to 600 × 300 × 260 mm.
- The T700W software drives the marking: Data Matrix ECC200, barcodes and logos, date / time / serial-number variables, material library, history generation.
- The station accepts ODBC, Excel, ASCII and CSV database links, as well as a barcode-reader, PLC or RS232 input.
