  • Abstract
    Minimally invasive therapy such as endoscopic surgery and catheter based intervention are being spread in many surgical intervention fields. Thus engineering assistance is important to realize safe and effective minimally invasive therapy. Computer Assisted Surgical guidance such as surgical navigation is one of key technologies. It is expected that application of robotic technology to minimally invasive surgery will provide the following functions:
    (1) Precise manipulation of biological tissues and surgical instruments in narrow and confined surgical field.
    (2) Precise and accurate localization of therapeutic devices using various pre and intra-operative medical information.In the first mode of application, more compact system is required. It can be realized by introduction of novel mechanical design and application off a new mechanism as well as new materials. At the same time integration with various energy devices are also required. Intra-operative guidance utilizing various pre and intra operative information is necessary in the second mode of application. Image guided robotic system for RF ablation, laser ablation, intensity modified radiation therapy, and high intensity focused ultrasound. In this type of robot, various preand intraoperative information including functional information is used to navigate the therapeutic devices to the target lesion. Intra-operative identification of pathological state of the target tissue and evaluation of outcome after therapeutic intervention are also important.Factors limiting the application of surgical navigation systems and medical robotics include limited usability requiring additional procedures for preparation, and high costs. Recent progress of computer vision technologies will solve part of these issues.For wider spread of these technologies in clinical environment, further improvement of usability, cost reduction, and accumulation of clinical evidences demonstrating efficacy from both clinical and economical point of view are required.

Ken Masamune, Tokyo Women’s Medical University

  • Abstract
    Nowadays, several medical devices/systems including imaging machine, anesthesia, navigation system, biomonitoring devices, surgical bed, medical robots, et al., are installed in the operation room, however, it is unpleasant situation that all devices are performed in stand-alone mode, without time-synchronization, and it is difficult to combine/analyze some set of information from devices to make surgeon’s decision during surgery. To improve this situation, we’ve been developing an integrated operating room named “Smart Cyber Operating Theater (SCOT) with middleware ORiN system. In this presentation, we introduce a current SCOT project and the design concept of new open platform architecture for the integration of master/slave robotic devices and information guided robot especially for oral and maxillofacial surgery. This design will accelerate the development of any types of robotic interfaces/end effectors with fast validation.

Jaesung Hong, Daegu Gyeongbuk Institute of Science and Technology

  • Abstract
    In these days, augmented reality (AR) has become a key technology for surgical navigation. Using the AR technology, the shape of invisible organs are overlapped to the visible endoscopic or microscopic images. Therefore the surgeon can avoid damaging the healthy tissue, and reduce the incision area. In the AR-based surgery, optical tracker and camera are generally used. Optical tracker can measure the position and pose of multiple markers, and the relationship between the camera and target organs of patient can be measured in real-time by tracking of the markers which are mounted on the camera body and the patient. In the AR display, finding the relationship between the optical marker mounted on the camera body and the center of camera (camera registration) is particulary important. This relationship strongly affects the overall accuracy of AR display. In this talk, the latest AR technologies applied for the surgical navigation are introduced.

    Jaesung Hong is an associate professor and the Department Chair of Robotics Engineering at the Daegu Gyeongbuk Institute of Science and Technology (DGIST), South Korea. His research area is medical imaging and medical robotics for minimally invasive surgery.
    At the University of Tokyo, he has developed the world first US-guided needle insertion robot tracking a movable and deformable organ. This was reported in Physics in Medicine and Biololgy in 2004, and has been frequently cited (> 160).

Ka-Wai Kwok, University of Hong Kong

  • Abstract
    Advanced surgical robotics has attracted significant research interest in supporting image guidance, even magnetic resonance imaging (MRI) for effective navigation of surgical instruments. In situ effective guidance of access routes to the target anatomy, rendered based on imaging data, can enable a distinct awareness of the position of robotic instrument tip relative to the target anatomy in various types of minimally invasive interventions. Therefore, such MRI-guided robots will rely on real-time processing the co-registration of surgical plan with the imaging data captured during the intervention, as well as computing the relative configuration between the instrument and the anatomy of surgical interest.
    This talk will present a compact robotic system capable to operate inside the bore of MRI scanner, as well as its solutions to technical challenges of providing a safe, effective catheter-based surgical manipulation. The proposed image processing system demonstrates its clinical potential of enhanced surgical safety by imposing visual feedback on tele-operated robotic instruments even under large-scale and rapid tissue deformations in soft tissue surgeries, such as cardiac electrophysiology and stereotactic neurosurgery. The ultimate research objective is to enable the operator to perform safe, precise and effective control of robotics instruments with the aid of pre- and intra-operative MRI models. The present work will be timely to bridge the current technical gap between MRI and surgical robotic control.

Hongliang Ren, National University of Singapore, Singapore

  • Abstract
    The feasibility of a needleless magnetic-actuated device for the purpose of intravitreal injections is investigated using three different design prototypes.
    A needleless device could potentially significantly reduce patient anxiety levels and occurrences of needle stick injuries to both healthcare workers and patients Moreover, a magnetic-actuated device allows for control of the current supplied over time to the device and the corresponding depth of penetration of the drug.
    Substitutes for the sclera and vitreous region were used in the experiments where a blue dye was injected using the two separate devices to identify if these devices were able to eject the liquid with enough force needed to penetrate the sclera and deliver the liquid to within the vitreous region and whether there was a relationship between the current supplied to the devices and the depth of delivery The solenoid prototype injector was not able to eject the liquid at a force required to penetrate the sclera although, because the vitreous region was a lot softer, a follow through current was predicted to be able to deliver the bulk of the liquid to the middle portion of the vitreous substitute used in this experiment. Moreover, the addition of a controller to the system was able to produce a two part force to the liquid, the initial peak force meant to penetrate the sclera and a follow through force to deliver the drug to the vitreous region only.
