1. A robot for image-guided interventions, comprising:
- a base member;
a platform; and
exactly five linear actuators connected in parallel between the base member and the platform, the linear actuators, the base member, and the platform being arranged so that the platform is moveable with respect to the base member, whereinthe linear actuators provide five degrees of freedom of movement of the platform relative to the base member and obstruct one degree of freedom of movement of the platform relative to the base member by preventing rotation of the platform about an axis of a needle,one of the five linear actuators obstructs the one degree of freedom of movement by preventing the rotation of the platform about the axis of the needle,the one linear actuator is operatively coupled to the base member and the platform, respectively, by two end joints of the same type, andthe remaining four linear actuators are each operatively coupled to the base member by a first end joint and each operatively coupled to the platform by a second end joint, the first end joint being a U-joint, and the second end joint being a spherical joint.

Abstract
Featured is a robot and a needle delivery apparatus. Such a robot comprises a plurality of actuators coupled to control locating any of number of intervention specific medical devices such as intervention specific needle injectors. Such a robot is usable with image guided interventions using any of a number of types of medical imaging devices or apparatuses including MRI. The end-effector can include an automated low needle delivery apparatus that is configured for dose radiation seed brachytherapy injection. Also featured is an automated seed magazine for delivering seeds to such an needle delivery apparatus adapted for brachytherapy seed injection.

15. A robotic system comprising
a robot including: -
a base member, a platform, and exactly five linear actuators connected in parallel between the base member and the platform, the linear actuators, the base member and platform being arranged so that the platform is moveable with respect to the base member; and a control unit that is operably coupled to each of the linear actuators, the control unit being configured to control operation of the robot, wherein the linear actuators provide five degrees of freedom of movement of the platform relative to the base member and obstruct one degree of freedom of movement of the platform relative to the base member by preventing rotation of the platform about an axis of a needle, one of the five linear actuators obstructs the one degree of freedom of movement by preventing the rotation of the platform about the axis of the needle, the one linear actuator is operatively coupled to the base member and the platform, respectively, by two end joints of the same type, and the remaining four linear actuators are each operatively coupled to the base member by a first end joint and each operatively coupled to the platform by a second end joint, the first end joint being a U-joint, and the second end joint being a spherical joint. - View Dependent Claims (16, 17, 18)
