SURGERY ROBOTS

MRI-Compatible Surgical Robots

MRI-P - A MRI-compatible robotic system for image-guided prostatic interventions: ablation, brachytherapy, and biopsy. The first stage product addresses only laser-based ablation. The robot actuators are ultrasonic motors. The robot has been used in a limited human trial.

MRI-P - robotic platform including: (i) a six-joint robot; (ii) robot-based trocar for mounting surgical tools; (iii) hand controller for navigating the surgical tool by remote control;  (iv) robot controller; (v) a Laptop-based user interface for robot control and image display; (vi) laser dispenser, power, and control; (v) MRI monitoring station (including MR Temperature mapping).

MRI-P could be adapted for operation in 1.5T-3T MRI scanners. The robot is functional simultaneously with the scanner in operation.

MRI-P is to navigate trocar-mounted surgical tools by remote or direct manual control. The system consists of: (i) a six-joint robot; (ii) robot-based trocar for mounting surgical tools; (iii) hand controller for navigating the surgical tool by remote control;  (iv) robot controller; (v) a Laptop-based user interface for robot control and image display; (vi) laser dispenser, power, and control; (v) MRI monitoring station (including MR Temperature mapping).

During surgical procedures, the patient lies on the MRI roll-in table with leg supports attached to the table. The robot is mounted & secured onto the table and between patient’s legs. The robot controller is at a distance from the scanner, connected to the robot, and to the Laptop that is located in the adjacent control room. The surgeon will remotely manipulate the tools based on MRI and Laptop-based images using a hand controller (joystick) or manually.  Control of surgical tool penetration is based on visual feedback provided by MR imaging.  The image allows the user to identify the tool tip location relative to the target, and perform suitable adjustments of the tool path to reach the target. When the tool is at the target, the laser is turned on, and ablation of tissue is performed.  MR thermography allows for real time imaging of tissue destruction. After the ablation process is completed, the scanner provides images of the heated and coagulated volumes of tissue.
