The percutaneous coronary interventions (PCI) require complex operating skills of the interventional devices and make the surgeons being exposed to heavy X-ray radiation. Accurate delivery of the interventional devices and avoiding the radiation are especially important for the surgeons. This paper presents a novel dedicated dual-finger robotic hand (DRH)(More)
Natural guidewire manipulations of surgeons in percutaneous coronary intervention (PCI), rotating and translating a guidewire with finger and hand motion, are important and useful references to build a knowledge base (KB) for robotic autonomous intervention. In this paper, guidewire manipulation models are proposed using an improved data glove, in which a(More)
Vascular interventional robot is becoming increasingly popular in assisting doctors for the treatment of cardiovascular diseases (CVDs). However, natural manipulations and motion patterns of surgeons in percutaneous coronary intervention (PCI), including finger motion and hand motion, are potentially altered more or less through this solution. Since(More)
In recent years, minimally invasive vascular surgery is widely applied in treatment of cardiovascular diseases, and the manipulation of the guidewire is the essential skill for this surgery. Lots of time and money have to be taken to achieve the skill. In this paper, we present a multithreading guidewire simulator which can help the apprentice to gain the(More)
For the treatment of cardiovascular diseases, clinical success of percutaneous coronary intervention is highly dependent on natural technical skills and dexterous manipulation strategies of surgeons. However, the increasing used robotic surgical systems have been designed without considering manipulation techniques, especially surgical behaviors and motion(More)
Robot-assisted vascular interventions present promising trend for reducing the X-ray radiation to the surgeon during the operation. However, the control methods in the current vascular interventional robots only repeat the manipulation of the surgeon. While under certain circumstances, it is necessary to scale the manipulation of the surgeon to obtain a(More)
Endoscopic Endonasal Approach (EEA) surgery, as a minimally invasive technique, is now the preferred treatment for most pituitary and skull base tumors. This procedure uses the nostrils as natural corridors to remove relevant lesions, which requires a high level hands-on skills and rich clinical experience. With the aid of virtual reality technology,(More)
