“…The proposed fluoroscopic-based dual-laser guided (Fluorolaser) navigation system consists of three major components: a Laser Guidance System (Nakajima, 2004) with built-in tracking capabilities using the hybrid Polaris Spectra (Northern Digital, Waterloo, ON, Canada); active infrared markers (AdapTrax 15 Marker, Northern Digital, Waterloo, ON, Canada); and a web camera (P1C30 series, Elecom, Osaka, Japan) used in place of an X-ray fluoroscope. We implemented the fluorolaser software using C++ (Visual Studio 2005, Microsoft co.) with OpenCV library.…”

“…Laser-based navigational guidance systems have been developed for spinal pin insertion and pelvic implant fixation surgeries (Sasama, 2002). It generates surgical plans and uses two laser beams to project point-of-entry and insertion orientation directly onto the patient's skin (Nakajima, 2004). Thus, a direct guidance is achieved and surgeons no longer need to mentally interpret positioning information from a screen.…”

This paper provides a novel method for intuitive and CT-less surgical navigation based on fluoroscopicbased navigation and laser guidance technology for minimal invasive orthopaedic surgery. This method does not require intra-operative registration of three-dimensional surface model derived from pre-operative CT/MRI volumes and is able to project surgical path planed intra-operatively onto the patient's skin directly. In this paper, implementation of this method and basic in vitro guidance accuracy validation were performed. Tool insertion path planning was performed on three 2D images from a pinhole imaging source taken at different incident angles. A 3D insertion pathway was generated and projected using two laser beams. Our Fluorolaser system has a planning accuracy of 1.07±0.60 mm, 0.73±0.38 degrees and an overall guidance accuracy of 1.11±0.62 mm, 0.80±0.68 degrees. These results demonstrate that the proposed method has great potentials to ensure accurate and intuitive surgical procedures.

Abstract. Percutaneous Vertebroplasty (PVP) is an effective and less invasive medical treatment for vertebral osteoporotic compression fractures. However, this operative procedure is quite difficult because an arcus vertebra, which is narrow, is needled with accuracy, and an operator's hand is exposed to X-ray continuously. We have developed a needle insertion robot for Percutaneous Vertebroplasty. Its experimental evaluation on the basic performance of the system and needle insertion accuracy are presented. A needle insertion robot is developed for PVP. This robot can puncture with accuracy and an operator does not need to be exposed to X-ray. The mechanism of the robot is compact in size (350 mm × D 400 mm × H270 mm, weight: 15 kg) so that the robot system can be inserted in the space between C-arm and the patient on the operating table. The robot system is controlled by the surgical navigation system where the appropriate needle trajectory is planned based on pre-operative three-dimensional CT images. The needle holding part of the robot is X-ray lucent so that the needle insertion process can be monitored by fluoroscopy. The position of the needle during insertion process can be continuously monitored. In vitro evaluation of the system showed that average position and orientation errors were less than 1.0 mm and 1.0 degree respectively. Experimental results showed that the safety mechanism called mechanical fuse released the needle holding disk properly when excessive force was applied to the needle. These experimental results demonstrated that the developed system has the satisfactory basic performance as needle insertion robot for PVP.
