ISO 6335-2:2026

Overview

ISO 6335-2:2026 – Surgical instruments - Staplers - Part 2: General requirements establishes general requirements for surgical staplers, setting out key aspects such as classification, intended performance, design attributes, evaluation, manufacturing processes, sterilization, packaging, and information that must be supplied by the manufacturer. This international standard applies specifically to single-use and reusable staplers which utilize staples in surgical procedures. By providing a harmonized framework, ISO 6335-2:2026 aims to improve product quality, safety, and consistency in the global medical device market, particularly in the context of surgical instrumentation.

Key Topics

• Classification: Defines various types of staplers based on use (single-use/reusable), function (cutter/non-cutter), surgical mode (open/endoscopic), staple layout (linear/circular), and drive mode (manual/powered).
• Intended Performance: Specifies requirements for clear description of device purpose, applicable tissues, and surgical modes to ensure intended safety and usability.
• Design Attributes: Addresses key considerations in product design to meet performance and safety goals, including compatibility, feedback mechanisms, mis-operation prevention, and support for various surgical techniques.
• Materials: Requires materials to be selected for biocompatibility, performance, and durability, with reference to international material standards.
• Design Evaluation: Outlines processes for pre-clinical and clinical evaluation, as well as ongoing post-market surveillance to ensure ongoing compliance.
• Manufacturing Requirements: Calls for manufacturing processes to minimize contamination and support consistent, conforming products.
• Sterilization: Provides requirements for both manufacturer-supplied sterile products and user sterilization, with verification against designated international sterilization standards.
• Packaging: Stipulates that packaging must protect the device through distribution and storage, maintaining sterility and integrity.
• Manufacturer Information: Details necessary labelling, instructions for use, and disclosure regarding proper usage, storage, potential risks, and product combinations.

Applications

ISO 6335-2:2026 is an essential reference for various sectors:

• Medical Device Manufacturers: Ensures that staplers meet high standards of safety, efficacy, and regulatory compliance from design to distribution.
• Healthcare Providers and Facilities: Assists in selecting reliable, standardized surgical staplers that support consistent clinical outcomes and patient safety.
• Quality and Regulatory Professionals: Provides criteria for audits, risk management, post-market surveillance, and regulatory submissions.
• Testing and Certification Bodies: Offers a basis for conducting conformity assessment, product evaluation, and certification against internationally recognized benchmarks.

By adhering to the requirements in ISO 6335-2:2026, organizations can reduce product risk, support patient safety, and facilitate international market access for surgical stapling instruments.
