Wrist and jaw assemblies for robotic surgical systems
An end effector for use and connection to a robot arm of a robotic surgical system, wherein the end effector is controlled and/or articulated by at least one cable extending from a respective motor of a control device of the robot surgical system, is provided. The end effector includes a wrist assembly, and a jaw assembly. The jaw assembly includes a cam pulley rotatably supported on at least one support plate of the jaw assembly, wherein the cam pulley is operatively connected to a proximal end of each of the jaws of the jaw assembly such that rotation of the cam pulley results in one of an opening and closing of the jaw assembly.
Gripper device for gripping laboratory vessels
A gripper device for gripping lids of laboratory vessels. The gripper device comprises a gripper unit with a main body, to which two gripper levers are each pivotably fastened by one end to a pivoting joint in each case. A gripper jaw is formed at the end of each gripper lever remote from the respective pivoting joint, such that the gripper jaws are arranged facing one another. A guiding element is provided which is movably mounted on the main body and two inner and outer guiding faces are formed on the guiding element or on the gripper levers respectively. The gripper levers or the guiding element each have a counter-guiding element which is arranged between one of the inner and one of the outer guiding faces, so that when the guiding element is moved, the gripper levers with their gripper jaws are pivoted apart or pressed together.
INDUSTRIAL MANIPULATOR GRIPPER PROVIDED WITH SENSOR AND METHOD FOR DETECTING THE PRESENCE OF A PIECE BETWEEN THE JAWS OF AN INDUSTRIAL MANIPULATOR GRIPPER
A gripper for industrial manipulators comprising a body, jaws constrained to the body and activable to hold and release a piece, an actuator of the jaws and a sensor configured to detect the presence of a piece between said jaws, is described. Advantageously, the sensor is not positioned between the jaws, in the space intended to accommodate the piece to be held, but is functionally interposed between the actuator and one of the jaws. A method for detecting the presence of a piece between the jaws of an industrial manipulator gripper, the method providing a sensor to be used to detect the position of a jaw with respect to the actuator of the gripper.
Rotational joint assembly for robotic medical system
An example rotational joint assembly for a robotic medical system, the rotational joint assembly comprising at least one arm segment and a rotational joint provided at one end of the arm segment. The rotational joint is to allow the arm segment to rotate about a rotational axis. The rotational joint comprising a brake to lock rotation of the arm segment at the rotational joint and an actuator to selectively engage or disengage the brake. The actuator comprising a cam having two stable regions separated by two transition regions, the two stable regions comprising a first stable region corresponding to engagement of the brake and a second stable region corresponding to disengagement of the brake.
Robotic surgical instrument
A robotic surgical instrument includes a housing, a shaft assembly extending distally from the housing, and an end effector assembly. The shaft assembly has a proximal segment coupled to the housing, a clevis supporting the end effector assembly, and at least one articulating link pivotably coupled to and interconnecting the proximal segment and the clevis such that the end effector assembly is configured to articulate relative to the proximal segment via the at least one articulating link in at least two directions.
Concentric Opposed Cam Actuator
An example device may include a rounded outer incline ramp and a rounded inner incline ramp surrounding a central axis. The rounded inner incline ramp and the rounded outer incline ramp may be inversely aligned relative to the central axis. The device may also include a piston carrier oriented in a direction parallel to the central axis. The piston carrier may include a first piston including a first roller positioned on the two ramps at a first point, where the first piston is configured to act on the two ramps in a direction parallel to the central axis. The piston carrier may also include a second piston including a second roller positioned on the two ramps at a second point opposite the first point, where the second piston is configured to act on the two ramps in a direction parallel to the central axis.
GRIPPER MECHANISM
A gripper mechanism includes a pair of gripper jaws, a linear actuator, and a rocker bogey. The linear actuator drives a first gripper jaw to move relative to a second gripper jaw. Here, the linear actuator includes a screw shaft and a drive nut where the drive nut includes a protrusion having protrusion axis expending along a length of the protrusion. The protrusion axis is perpendicular to an actuation axis of the linear actuator along a length of the screw shaft. The rocker bogey is coupled to the drive nut at the protrusion to form a pivot point for the rocker bogey and to enable the rocker bogey to pivot about the protrusion axis when the linear actuator drives the first gripper jaw to move relative to the second gripper jaw.
Industrial manipulator gripper provided with sensor and method for detecting the presence of a piece between the jaws of an industrial manipulator gripper
A gripper for industrial manipulators includes a body, jaws constrained to the body and activatable to hold and release a piece, an actuator of the jaws and a sensor configured to detect the presence of a piece between said jaws, is described. Advantageously, the sensor is not positioned between the jaws, in the space intended to accommodate the piece to be held, but is functionally interposed between the actuator and one of the jaws. A method for detecting the presence of a piece between the jaws of an industrial manipulator gripper includes providing a sensor usable to detect the position of a jaw with respect to the actuator of the gripper.
Static electricity prevention device
A static electricity prevention device includes a main body, an air ionizing generator, a first griping arm, a second griping arm and a driving unit. The main body includes a receiving cavity. The air ionizing generator is fixed on the main body and configured for ejecting ionized air. The first griping arm and the second griping arm each comprises a gripping end and a supporting end connected with the gripping end, the first griping arm and the second griping arm are pivotally mounted on the ends of the main body. The driving unit is arranged in the receiving cavity, and configured for driving the supporting end to rotate, and in order to open or close the gripping end.
