In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, the number of this surgery tends to increase. However, doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. When doctors operate by remote control, there is possibility that parts of the robot collide with peripheral devices or a patient. Especially, if in the case of collision with the patient, it could become a serious incident. Accordingly, it is important to build a suitable path plan of the needle insertion before the surgery. Doctors, however, currently, do not have methods to grasp the possibility of the collision. Therefore, a simulation which detect collision with a patient in the advanced planning is proposed in this paper. The effectiveness of proposed simulation is confirmed.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, but doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. We are currently developing an automated puncture system. Deviation of puncture point on body surface causes needle deflection during the automatic puncture. Because the needle deflection grows with the inserted depth, it makes the needle difficult to reach the target tumor. So as to solve them, the floating mechanism is developed to suppress needle deflection. Displacement sensor on floating mechanism can measure the movement of the floating part. In addition, the puncture reaction force can be measured by the force sensor on the robot. Algorithms to suppress the needle deflection using this information are proposed in this paper.

Detection of abnormal states of insertion by a force sensor for a CT-guided needle insertion robot

A remote-controlled robot for CT-guided needle insertion has been developed to prevent a doctor from radiation exposure. However, it is difficult for a doctor to recognize abnormal states of insertion when the doctor uses the robot because the doctor cannot obtain force sense information from the needle directly. Such an abnormal state occurs when a needle contacts with a bone. Therefore, we propose detecting abnormal states of insertion if force sensor value exceed a threshold and stopping the robot automatically. First, we conducted experiments to determine thresholds. We measured force values when a doctor feels the sign of plastic deformation in needles. In consideration of the stop time delay, thresholds were set by subtracting the rise values of force from the measured force values. Then, we verified that the robot can stop appropriately by the thresholds without occurring plastic deformation.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, but doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. As a research topic, automated needle puncturing by the robot is focused on. However, currently the robot cannot obtain CT image in real time. So, the robot cannot obtain the form of needle based on CT image and cannot control state of needle accurately. On the other hands, we aim that the robot moves automatically for restraining a bend of needle. As the first step for this, the method to estimate a form of needle by using a force sensor information is proposed in this paper. If a form of the needle is displayed in user interface, it become easy for doctors to remove a bend of the needle during surgery with remote-controlled IR assistance robot. Additionally, we conducts the experiment to confirm effectiveness of proposed method.
