A dovetail tool changer includes a first plate to be constrained to an external handling system, a second plate to be constrained to a tool and locking device to lock the second plate in the first plate. The second plate is insertable along a longitudinal direction in a pocket defined in the first plate, both plates have complementary cross sectional shapes and define a dovetailed coupling. The locking device includes at least one floating element movable between a lock position at which it exerts a thrust onto the second plate preventing disengagement thereof from the first plate, and an unlock position, at which the second plate can be separated from the first plate. The locking device includes at least one thrust element connected to the at least one floating element, which are together able to be displaced along a first direction in response to an exerted user force.

A method of assembling a robotic surgical tool includes providing a handle having first and second ends, a lead screw, and a spline extendable between the first and second ends. The lead screw is rotated in a first direction to translate an elevator layer of a carriage proximally along a longitudinal axis of the handle, the elevator layer being movably mounted to the lead screw at a carriage nut. One or more additional layers of the carriage are removably coupled to the elevator layer and an elongate shaft extends distally from the additional layers, and an end effector is arranged at a distal end of the shaft. The elevator layer is penetrated by the end effector and the shaft upon coupling the additional layers to the elevator layer, and the lead screw is rotated in a second direction opposite the first direction to translate the carriage distally.

A robotic surgical tool comprises a stage assembly and a core assembly removably mountable to the stage assembly. The stage assembly may comprise a lead screw and at least one spline extendable between first and second ends of the stage assembly, and a nut rotatably mounted to the lead screw to translate between the first and second ends upon rotation of the lead screw. The core assembly may comprise a drive housing that is movably mountable to the stage assembly to translate, with the nut, between the first and second ends of the stage assembly. The surgical tool may also comprise a shroud assembly having a primary shroud and a secondary shroud, the primary shroud at least partially enclosing the core assembly when installed on the stage assembly, and the secondary shroud being movable between a first position, where the secondary shroud occludes an opening in the primary shroud, and a second position, where the opening in the primary shroud is exposed. The secondary shroud may be pivotally attached to the primary shroud at a hinge. The secondary shroud may be slidingly attached to the primary shroud, such that the secondary shroud is circumferentially revolvable relative to the primary shroud between the first and second positions. The secondary shroud may be slidingly attached to the primary shroud, such that the secondary shroud is axially slidable relative to the primary shroud between the first and second positions.

The invention relates to a slim and long multifunctional gripping mechanism with bending- and torsion-resistant structure, on which several finger, suction, magnetic head and other mechanisms for a multitude of tasks are arranged.

The gripper arm is composed in sandwich configuration of several cages placed on top of each other, like a multi-stage tower. The individual cages consist of two plates in parallel in lightweight construction, with their mutual distance being ensured by several rods, spokes, wires, ropes and strings. Most of the drives are contained within the first cage after the flange. From that position, all mechanisms participating in the action of the gripper are driven by rods, shafts, ropes, chains or belts traversing the cages. Further cages are used to attach and accommodate the components of finger mechanisms. Movable cages are used as drives for finger, suction or magnetic head mechanisms. Several finger mechanisms perform a different task each, individually or in groups (FIG. 12).
