ASTM is one of the leading standards developers for medical devices. With 24 categories, addressing everything from surgical implements to automated analysis, ASTM medical device standards cover a truly wide range. With how much research and training goes into the medical industry, standardization plays a key role in productively actualizing that effort. Organized below for your convenience by usage, industry, and theme are over 300 standards. This list includes standards related to Computer Assisted Orthopaedic Surgical Systems.
1.1 This standard will measure the effects on the accuracy of computer assisted surgery (CAS) systems of the environmental influences caused by equipment utilized for bone preparation during the intended clinical application for the system. The environmental vibration effect covered in this standard will include mechanical vibration from: cutting saw (sagittal or reciprocating), burrs, drills, and impact loading. The change in accuracy from detaching and re-attaching or disturbing a restrained connection that does not by design require repeating the registration process of a reference base will also be measured. 1.2 It should be noted that one system may need to undergo multiple iterations (one for each clinical application) of this standard to document its accuracy during different clinical applications since each procedure may have different exposure to outside forces given the surgical procedure variability from one procedure to the next. 1.3 All units of measure will be reported as millimeters for this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
1.1 This document provides procedures for measurement and reporting of basic static performance of surgical navigation and/or robotic positioning devices under defined conditions. They can be performed on a subsystem (for example, tracking only) or a full computer-aided surgery system as would be used clinically. Testing a subsystem does not mean that the whole system has been tested. The functionality to be tested based on this practice is limited to the performance (accuracy in terms of bias and precision) of the system regarding point localization in space by means of a pointer. A point in space has no orientation; only multidimensional objects have orientation. Therefore, orientation of objects is not within the scope of this practice. However, in localizing a point the different orientations of the pointer can produce errors. These errors and the pointer orientation are within the scope of this practice. The aim is to provide a standardized measurement of performance variables by which end users can compare within a system (for example, with different reference elements or pointers) and between different systems (for example, from different manufacturers). Parameters to be evaluated include (based upon the features of the system being evaluated): (1) Accuracy of a single point relative to a coordinate system. (2) Sensitivity of tracking accuracy due to changes in pointer orientation. (3) Relative point-to-point accuracy. 1.1.1 This method covers all configurations of the evaluated system as well as extreme placements across the measurement volume. 1.2 This practice defines a standardized reporting format, which includes definition of the coordinate systems to be used for reporting the measurements, and statistical measures (for example, mean, RMS, and maximum error). 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard, except for angular measurements, which may be reported in terms of radians or degrees. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
