Instruments for surgery - Scalpels with detachable blades - Fitting dimensions
Lays down the dimensions of two sizes of fitting features for detacheable scalpel blades and the handles with which they are used. It secures a good fitting and interchangeability of detachable blades for scalpels manufactured in different countries or by different manufacturers. The transitional period for a gradual adaption of the fitting dimensions specified in this standard should end with the year 1990.

General Information
Overview
ISO 7740:1985 specifies the fitting dimensions for scalpels with detachable blades and the corresponding handles. The standard establishes two sizes of fitting features (commonly referred to as a small fitting feature, No. 3, and a large fitting feature, No. 4) to secure a consistent fit and interchangeability between blades and handles manufactured by different suppliers and in different countries. A transitional adoption period for these dimensions concluded in 1990.
This International Standard was prepared by ISO/TC 170 (Surgical instruments) and includes dimension tables and illustrative figures for the fitting area. The illustrated blade design is informative only and not part of the mandatory requirements.
Key Topics
- Scope and purpose: Defines dimensions to ensure good fitting and interchangeability of detachable scalpel blades and handles.
- Two fitting sizes: Small fitting feature (No. 3) and large fitting feature (No. 4) with corresponding dimension ranges for blade and handle mating parts.
- Dimension tables and figures: Numerical tolerances and illustrative figures are provided for the fitting area; manufacturers should use these when designing mating parts.
- Transitional period: The standard set a five-year transition ending on 31 December 1990 to allow gradual adoption.
- Quality and conformity: Emphasis on reproducible dimensions to improve safety and reduce mismatches during surgical procedures.
Applications
ISO 7740:1985 is directly applicable to the following practical areas:
- Manufacturing: Tooling and production drawings for scalpel blades and handles should reference the fitting dimensions to ensure interchangeability.
- Product design & R&D: Design engineers can use the specified fittings to create components compatible with a wide market of existing blades or handles.
- Quality control: Inspection and acceptance testing can reference the dimensional tolerances and figures in the standard to verify conformity.
- Procurement & inventory: Hospitals and medical device purchasers can specify ISO 7740 compatibility to avoid mismatched blade-handle combinations.
- Regulatory compliance: Supports conformity evidence for medical device submissions where interoperability of surgical instruments is required.
Related Standards
- Prepared by ISO/TC 170 (Surgical instruments); users should consult the technical committee outputs for related guidance.
- The standard notes that references to other ISO documents imply their latest editions; consult current ISO surgical instrument standards and national medical device regulations for comprehensive compliance.
Keywords: ISO 7740, scalpels, detachable blades, fitting dimensions, handles, interchangeability, surgical instruments.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Each member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 7740 was prepared by Technical Committee ISO/TC 170,
Surgical instruments.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
