    Abstract: An actuator device includes a base body that defines a receiving space. A first end subunit has a ventilation hole, a first oil injection hole, and a first oil injection nozzle extending from the first oil injection hole into the receiving space. A second end subunit is connected to the base body. A sliding unit is slidable relative to the base body, and has a slide table, a nut seat connected to the slide table, and a connection hole connected to the slide table and the base body. A pressure relief unit is mounted in the ventilation hole for allowing air to be discharged from the receiving space to an external environment. A driving unit is operable for driving movement of the sliding unit.

    Abstract: A normal-time drive cam groove extends from a drive cam specific point, which is defined as a specific point of the drive cam, toward one side in a circumferential direction of the drive cam. A groove bottom at the normal-time drive cam groove is sloped relative to one end surface of the drive cam such that a depth of the groove bottom continuously decreases from the drive cam specific point toward the one side in the circumferential direction of the drive cam. An emergency-time drive cam groove extends from the drive cam specific point toward another side in the circumferential direction of the drive cam.

    Abstract: At a drive cam slope groove, a groove bottom is sloped relative to one end surface of a drive cam such that a depth of the groove bottom continuously decreases from one side toward other side in a circumferential direction. At a drive cam planar groove, the groove bottom is parallel to the one end surface of the drive cam. A drive cam connection groove has: one end connected to an end of the drive cam slope groove located on the other side in the circumferential direction of the drive cam; and the other end connected to an end of the drive cam planar groove located on the one side in the circumferential direction. A slope angle of the groove bottom relative to the one end surface of the drive cam continuously changes from the one end to the other end of the drive cam connection groove.

    Abstract: A device including a frame; an actuator attached to the frame and slidaby movable with respect to the frame along a linear axis, and a helical member positioned within the frame and rotatably movable with respect to the frame about a helical axis of the helical member, wherein the helical axis is parallel to the linear axis, wherein the actuator and the helical member are configured to cooperate with one another such that (a) motion of the actuator along the linear axis in a first linear direction causes corresponding rotation of the helical member about the helical axis in a first rotational direction and (b) motion of the actuator along the linear axis in a second linear direction that is opposite the first linear direction causes corresponding rotation of the helical member about the helical axis in a second rotational direction that is opposite the first rotational direction.

    Abstract: Disclosed are a telescopic assembly and an occlusion mechanism. The telescopic assembly includes a rotating shaft, a telescopic piece, and a connecting piece; two spiral orbits extending in an axis direction are disposed on the circumferential side of the rotating shaft, and the spiral orbits are rotatably intersected with each other and communicate on tail ends to form a closed orbit; the telescopic piece sleeves around the rotating shaft; the connecting piece is movably connected to the telescopic piece, and the other end of the connecting piece moves in a spiral orbit groove all the time during movement; and with the rotation of the rotating shaft, the connecting piece drives the telescopic piece to do reciprocating movement along an axis so that the automatic telescopic movement of the telescopic piece is achieved. The telescopic assembly pushes a first rocking bar and a second rocking bar to achieve an occlusion action.

    Abstract: An actuator assembly is provided for converting rotation into linear displacement including a linear fluid dispensing tube for linear displacement. Hemispherical lugs are monolithically formed on the linear member. A primary gear includes a central bore having helix grooves formed into a surface of the central bore. The helix grooves receive the hemispherical lugs so that each helix groove mates with a respective hemispherical lug to reduce friction, so that hemispherical lugs slide smoothly within the respective helix grooves. Linear projections are formed on the exterior surface of the dispensing tube and extend longitudinally along the dispensing tube. A projecting portion has an aperture for receiving and guiding the dispensing tube through the linear displacement. Mating grooves are formed on an interior of the projecting portion for receiving and guiding the linear projections, thereby preventing the dispensing tube from rotating during travel.

    Abstract: Apparatus is described for administering a substance to a subject. A vial contains the substance and a stopper is disposed within the vial and is slidably coupled to the vial. A first threaded element is (a) rotatable with respect to the vial and (b) substantially immobile proximally with respect to the vial during rotation of the first threaded element. A second threaded element is threadedly coupled to the first threaded element. At least a distal end of the second threaded element is substantially non-rotatable with respect to the vial, and the distal end of the second threaded element defines a coupling portion that couples the second threaded element to the stopper. The first threaded element, by rotating, linearly advances the stopper and at least the distal end of the second threaded element toward a distal end of the vial. Other embodiments are also described.
