Significance and Use
5.1 The purpose of this practice is to provide data that can be used for comparison and evaluation of the accuracy of different CAS systems.
5.2 The use of CAS systems and robotic tracking systems is becoming increasingly common and requires a degree of trust by the user that the data provided by the system meets necessary accuracy requirements. In order to evaluate the potential use of these systems, and to make informed decisions about suitability of a system for a given procedure, objective performance data of such systems are necessary. While the end user will ultimately want to know the accuracy parameters of a system under clinical application, the first step must be to characterize the digitization accuracy of the tracking subsystem in a controlled environment under controlled conditions.
5.3 In order to make comparisons within and between systems, a standardized way of measuring and reporting point accuracy is needed. Parameters such as coordinate system, units of measure, terminology, and operational conditions must be standardized.
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 and health practices and determine the applicability of regulatory limitations prior to use.
