An assembly is disclosed for positioning elongate instruments for percutaneous procedures. The assembly has a first guiding member with a first body, a first guiding hole extending through the first body for receiving a coiled instrument, the first guiding hole having a first axis. The assembly further includes a second guiding hole, wherein the second guiding hole is coaxial with the first guiding hole and has an essentially cylindrical shape. The first guiding hole extends at a periphery of the second guiding hole. A second guiding member has a second body with opposite first and second main surfaces, a third guiding hole having an essentially cylindrical shape and extending through the second body. The second guiding member is attached or attachable to a periphery of the first guiding member such that the third guiding hole has an axis substantially parallel to the first axis.

A surgical robotic platform operates within a constrained space of an imaging scanner in which a patient resides. The platform includes a gross positioning stage configured to be located outside of the constrained space An end-effector having a rotatable shaft is extendable from the gross positioning stage and into the constrained space of the imaging scanner. The shaft has a proximal end operatively coupled to the positioning stage outside of the constrained space and a distal end configured to be located in the constrained space. The distal end has a medical instrument gripper for holding a medical instrument used in a percutaneous procedure. The end-effector further includes a joint arrangement operatively coupling the shaft to the medical gripper for providing motion to the medical instrument gripper for enabling position and / or orientation control of the medical instrument. A drive module controls the joint arrangement.

The utility model discloses percutaneous operation intervention equipment based on four-axis inner double-point dynamic constraint, which comprises a base, four groups of connecting arms and an adjusting table, the connecting arms are uniformly distributed between the base and the adjusting table, two ends of each connecting arm are respectively in spherical hinge connection with the base and the adjusting table, the base is provided with a positioning piece, and the positioning piece is arranged on the adjusting table. The center position of the adjusting table and the positioning piece are both connected with ball joints, and intervention tools are arranged on the two ball joints in a penetrating mode. The method has the advantages of avoiding the deviation of an intervention tool and improving the stability and accuracy of intervention operation.
