Articulation mechanisms for surgical instruments such as for use in robotic surgical systems
An articulation assembly, surgical instrument including the same, and robotic surgical system including the same. The articulation assembly includes a lead screw assembly including a lead screw and a collar operably engaged about the lead screw such that rotation of the lead screw translates the collar about the lead screw. The lead screw defines a proximal input end rotatably received within a first base assembly and a distal dock end rotatably received within a second base assembly. An articulation cable is operably coupled to the collar such that movement of the collar about the lead screw tensions or de-tensions the articulation cable. A set screw is threadingly engaged within the second base assembly and operably coupled to the distal dock end of the lead screw such that proximal rotational driving of the set screw urges the lead screw proximally, thereby urging the collar proximally to tension the articulation cable.
VERTICAL ARTICULATED ROBOT AND TWO-AXIS ROBOT
A vertical articulated robot includes a first joint axis portion including a first motor configured to rotationally drive a tool flange, and a second joint axis portion including a second motor configured to rotationally drive the first joint axis portion. The first motor includes a portion that overlaps the second motor in a direction orthogonal to both a direction in which a first rotation axis extends and a direction in which a second rotation axis extends.
VERTICAL ARTICULATED ROBOT
A vertical articulated robot includes a plurality of joint axis portion units configured to rotationally drive a plurality of arms, and a wiring unit configured to allow wiring portions of the plurality of joint axis portion units to be arranged therein. A joint axis portion unit integrally includes a first motor including a solid first motor shaft and a first speed reducer directly connected to the first motor shaft.
LIGHTWEIGHT HIGH LOAD-BEARING REDUCER AND METHOD FOR GENERATING BIONIC BONE STRUCTURE OF GEAR THEREOF

The reducer gear comprises: an outer contour layer and a reticulated porous base layer cladded by the outer contour layer; the outer contour layer comprises a mounting surface layer, a tooth surface layer, and a connecting surface layer connected between the mounting surface layer and the tooth surface layer and forming a complete gear outer contour together with the mounting surface layer and the tooth surface layer; the mounting surface layer, the tooth surface layer and the connecting surface layer are compact structures; the reticular porous base layer is located in a cavity formed by the outer contour layer, and fiber trabeculae in a porous grid structure are provided in the reticular porous base layer.
Cycloidal transmission with torque detection mechanism
A cycloidal transmission for a drive includes a housing, a drive shaft, an eccentric, a cam plate, a pin plate, an output shaft, and a torque detection mechanism. The housing includes a first bearing, a second bearing, and a rolling ring. The drive shaft is rotatably mounted in the first bearing. The eccentric is fixedly connected to the drive shaft. The cam plate is driven by the eccentric. The cam plate is configured to roll in the rolling ring. Pins of the pin plate are configured to engage holes of the cam plate, so that the pin plate is driven by the cam plate. The output shaft is fixedly connected to the pin plate. The output shaft is rotatably mounted in the second bearing. The torque detection mechanism is between the first bearing and the second bearing and configured to detect the torque of the output shaft.
Translatable barrel cam of a robotic surgical system
A surgical instrument including an end effector, a shaft assembly defining a longitudinal axis extending proximally from the end effector, a first drive operatively connected to a first portion of at least one of the end effector or the shaft assembly, and an activating mechanism operatively connected to the first drive. The first drive longitudinally translates relative to the longitudinal axis from a first drive position toward a second drive position to respectively actuate the first portion from a first portion position toward a second portion. The activating mechanism selectively direct translation of the first drive from the first drive position toward the second drive position by rotating from a first rotational body position toward a second rotational body position or translating from a first translational body position toward a second translational body position.
