Port wine stain (PWS) birthmarks are congenital vascular malformations, which usually appear at birth and tend to become darker and thicker with age's growth. Vasculartargeted photodynamic therapy (PDT) is an effective approach in the treatment of PWS. However, due to the arbitrariness of manual operation and pole points existing in laser radiation, the PWS zone was always cured unevenly in clinics...
This article proposes one kind of ultrasonic imaging guided medical robot system with a six-joint arm. This system can detect the real-time space position of the ultrasonic probe by sensors in six joints of the arm. In the microwave ablation liver neoplasm treatment, when the six-joint arm holds the ultrasonic probe to scan on the body surface of a patient, the system's microcomputer can determinate...
Radio frequency ablation destroys a tumour by delivering radio frequency energy through a needle probe, minimally invasive surgery robot of five degrees freedom has been developed for assisting surgeons to place the probe accurately at the target. The minimally invasive surgery robot drives the ablator tool to track the tumor when the tumor moves in real time and precise orientate to the tumor. Therefore...
The radio frequency ablation operation is performed as a means of minimally invasive surgery. In this method, the ablation tool is inserted into the tumor center based on the transcutaneous ultrasonography navigation, then, the surgeons guarantee the toolpsilas point in the tumorpsilas center in entire operations. According to the task of the surgical operation, a small and compact medical robot is...
Radio frequency ablation of non-resectable malignant tissue in a patientpsilas liver is a rapidly expanding treatment tool for clinicians, because the operation result is smaller incision, therefore there is significantly reduced tissue trauma and short recovery time. But, the minimally invasive surgery only experienced surgeons can do, and need a long time, which bring maximum burden to surgeons...
