Abstract

In order to improve the usability of surgical navigation systems, this paper presents the design, implementation and testing of a mobile wireless tracking camera cart for intraoperative use. The tracking data, i.e., tool poses, are made available on the operating room (OR) network by means of the manufacturer-independent communication standard ISO IEEE 11073 (“SDC”). In this way, the wireless tracking system (WTS) can act as a modular localization service for various medical devices such as robots and navigation software.
The concept and implementation of the battery-powered wireless tracking cart is shown. The paper furthermore evaluates how the use of a new software library improves latency and reliability in contrast to previous implementations.
The results indicate that the new software library and the wireless data transfer do indeed meet the required latency of 50 milliseconds for hand-eye coordination tasks with a reliability of 99.395% even when the network is under OR-typical load. However, as the library does not offer any additional safety determinism, increased maximum latency times may occur in individual cases, making the device unsafe for intraoperative use.
