“…In the area of laparoscopic surgery, there are efforts towards introducing the laser as a tool for treating soft tissue. Smith presented an idea for combining optical fiber diode lasers for cardiac surgery with the daVinci surgical robot7. Even though he did not present a concrete concept, Smith expects that coupling of laser methodology and surgical robotics will allow for more precise direction of the laser energy.…”

“…Surgery for AF involves creating scar tissue that isolates irregular electrical impulses and prevents their conduction to the rest of the heart. With developments in port access techniques, the use of focused energy delivery based on radiofrequency, microware, cryoablation, and bipolar cautery has been preferred over the conventional approach [1,2]. More recently laser sources have also been proposed for controlled heating of the tissue and forming electrical impedance while preserving the tissue's structural coherence [2].…”

Abstract. The use of focused energy delivery in robotic assisted surgery for atrial fibrillation requires accurate prescription of ablation paths. In this paper, an original framework based on fusing human and machine vision for providing gaze-contigent control in robotic assisted surgery is provided. With the proposed method, binocular eye tracking is used to estimate the 3D fixations of the surgeon, which are further refined by considering the camera geometry and the consistency of image features at reprojected fixations. Nonparametric clustering is then used to optimize the point distribution to provide an accurate ablation path. For experimental validation, a study where eight subjects prescribe an ablation path on the right atrium of the heart using only their gaze control is presented. The accuracy of the proposed method is validated using a phantom heart model with known 3D ground truth.

Despite the potential increase in precision and accuracy, laser technology is not widely used in neurological surgery. This in part relates to challenges associated with the early introduction of lasers into neurosurgery. Considerable advances in laser technology have occurred, which together with robotic technology could create an ideal platform for neurosurgical application. In this study, a 980-nm contact diode laser was integrated with neuroArm. Preclinical evaluation involved partial hepatectomy, bilateral nephrectomy, splenectomy, and bilateral submandibular gland excision in a Sprague-Dawley rat model (n = 50). Total surgical time, blood loss as weight of surgical gauze before and after the procedure, and the incidence of thermal, vascular, or lethal injury were recorded and converted to an overall performance score. Thermal damage was evaluated in the liver using tissue samples stained with hematoxylin and eosin. Clinical studies involved step-wise integration of the 980-nm laser system into four neurosurgical cases. Results demonstrate the successful integration of contact laser technology into microsurgery, with and without robotic assistance. In preclinical studies, the laser improved microsurgical performance and reduced thermal damage, while neuroArm decreased intra- and intersurgeon variability. Clinical studies demonstrate dutility in meningioma resection (n = 4). Together, laser and robotic technology offered a more consistent, expedient, and precise tool for microsurgery.

Robots and lasers: the future of cardiac tissue ablation?

Abstract: While traditional energy sources focus on applying heat-based elements to the tissue's surface allowing temperature to propagate across the thickness of the tissue laser is an innovative, tissue-specific energy for creating tissue ablation.
