Stereotactic body radiation therapy (SBRT) stems from the initial developments of intra-cranial stereotactic radiosurgery (SRS). Despite similarity in their names and clinical goals of delivering a sufficiently high tumoricidal dose, maximal sparing of the surrounding normal tissues and a short treatment course, SBRT technologies have transformed from the early days of body frame-based treatments with X-ray verification to primarily image-guided procedures with cone-beam CT or stereoscopic X-ray systems and non-rigid body immo-bilization...

Anesthesiologists and the perioperative team have a tremendous impact upon clinical outcomes in robotic-assisted thoracoscopic surgery. As anesthesiology is developing its role outside the operating room, the patient population benefits from an expanded focus on perioperative critical care and pain management. This review focuses upon the preoperative optimization, unique intraoperative considerations for surgeons and anesthesiologists, and postoperative management of patients undergoing robotic-assisted thoracoscopic surgery...

Despite the versatility of synthetic chemistry, certain combinations of mechanical softness, strength, and toughness can be difficult to achieve in a single material. These combinations are, however, commonplace in biological tissues, and are therefore needed for applications such as medical implants, tissue engineering, soft robotics, and wearable electronics. Present materials synthesis strategies are predominantly Edisonian, involving the empirical mixing of assorted monomers, crosslinking schemes, and occluded swelling agents, but this approach yields limited property control...

Powered exoskeletons can facilitate rehabilitation of patients with upper limb disabilities. Designs using rotary motors usually result in bulky exoskeletons to reduce the problem of moving inertia. This paper presents a new linearly actuated elbow exoskeleton that consists of a slider crank mechanism and a linear motor. The linear motor is placed beside the upper arm and closer to shoulder joint. Thus better inertia properties can be achieved while lightweight and compactness are maintained. A passive joint is introduced to compensate for the exoskeleton-elbow misalignment and intersubject size variation...

Numerous published articles have shown the safety and efficacy of robotic lung resection, including lobectomy. The robotic approach offers similar survival rate to the open and video-assisted thoracoscopic surgery methods. Potential advantages provided by robotic technology, such as three-dimensional (3D) high-quality camera, wristed tools and ergonomic ease that seems to overcome certain video-assisted thoracic surgery (VATS) limits have been widely described. Several techniques have been developed by different surgeons to perform a robotic lobectomy...

Robotic-assisted pulmonary lobectomy can be considered for patients fit for conventional lobectomy. Contraindications include prohibitive lung function or medical comorbidities, multistation N2, gross N2 disease, or evidence of N3 disease. Team training, familiarity with equipment, troubleshooting, and preparation are critical for successful robotic lobectomy. Similar to video-assisted thoracoscopic surgery (VATS) lobectomy, robotic lobectomy is associated with decreased blood loss, blood transfusion, air leak, chest tube duration, duration of stay, and mortality compared with thoracotomy...

PURPOSE: Currently, lung brachytherapy in clinical setting is a complex procedure. Operation accuracy depends on accurate positioning of the template; however, it is difficult to guarantee the positioning accuracy manually. Application of robotic-assisted systems can simplify the procedure and improve the manual positioning accuracy. Therefore, a novel CT-guided robotic system was developed to assist the lung cancer brachytherapy. METHODS: A four degree-of-freedom (DOF) robot, controlled by a lung brachytherapy treatment planning system (TPS) software, was designed and manufactured to assist the template positioning...

BACKGROUND: Epithelioid haemangioendothelioma (EHE) is a rare low-grade vascular neoplasm that can arise in the lung, liver, soft tissues or, less commonly, bone. Due to its low prevalence of less than one in a million and its non-specific clinical features, EHE is often misdiagnosed and managed inappropriately. Here we discuss the case of a 58 year-old gentleman with mediastinal EHE and review existing literature on pulmonary EHE (PEH). CASE HISTORY: A 58 year-old gentleman presented to our outpatient Clinic with chest discomfort and palpitations...

The intraoperative identification of small pulmonary nodules through video-assisted thoracoscopic surgery remains challenging. Although preoperative CT-guided nodule localization is commonly used to detect tumors during video-assisted thoracoscopic surgery (VATS), this approach carries inherent risks. We report the case of a patient with stage I lung cancer presenting as an area of ground-glass opacity (GGO) in the right upper pulmonary lobe. He successfully underwent a single-stage, CT-guided localization and removal of the pulmonary nodule within a hybrid operating room (OR) equipped with a robotic C-arm...
