Robot-assisted needle insertion for venous catheterization
Vein access can be challenging for a variety of patients. The development of robots-assisted central or peripheral veins puncture would facilitate life of health professionals and patients. New robots are under development for this purpose and probably they will become available for practical use in the near future. These techniques may decrease significantly the cost of medicine, which current...
متن کاملModeling of Needle Insertion Forces for Robot-Assisted Percutaneous Therapy
Force information from needle insertions was measured and modeled for use in robot-assisted percutaneous therapies. Data was collected on bovine livers using the Johns Hopkins University Steady Hand Robot, and modeled in three parts: force due to capsule stiffness, friction, and cutting. Capsule stiffness is modeled by a nonlinear spring model, friction by a modified Karnopp model, and cutting ...
متن کاملExperimental analysis of robot-assisted needle insertion into porcine liver.
How to improve placement accuracy of needle insertion into liver tissue is of paramount interest to physicians. A robot-assisted system was developed to experimentally demonstrate its advantages in needle insertion surgeries. Experiments of needle insertion into porcine liver tissue were performed with conic tip needle (diameter 8 mm) and bevel tip needle (diameter 1.5 mm) in this study. Manual...
متن کاملRobot-Assisted Needle Alignment with Image-Guided Teleoperated Needle Insertion for Prostate Cancer Interventions
Figure 2: The robotic system developed for MR image-guided prostate biopsy and brachytherapy. The robot operates inside the bore during imaging, is registered to the scanner using a fiducial frame, and aligns the needle to targets selected in intraoperative MR imaging. The needle is inserted using a master device that lets the clinician stand beside the patient, view real-time MR images aligned...
متن کاملExperimental evaluation of magnified haptic feedback for robot-assisted needle insertion and palpation.
BACKGROUND Haptic feedback has been proven to play a key role in enhancing the performance of teleoperated medical procedures. However, due to safety issues, commercially-available medical robots do not currently provide the clinician with haptic feedback. METHODS This work presents the experimental evaluation of a teleoperation system for robot-assisted medical procedures able to provide mag...
