A drive mechanism for a medication delivery device containing a resilient member and having a rotation member configured to be rotated in a first direction during setting of a dose of a medication and to be rotated in a second direction during delivery of the dose, where the rotation member is coupled to a drive member that is coupled to a piston rod such that on dose delivery the piston rod is displaced in a distal direction to dispense a medicament and where the resilient member prevents movement of the drive member and the piston rod during dose setting.

A surgical device adapter for coupling an end effector to a handle assembly is disclosed. The surgical device adapter includes: a housing; a drive mechanism disposed within the housing and couplable to the handle assembly and the end effector; and a drive coupling assembly coupled to the surgical device adapter and selectively couplable to the handle assembly, the drive coupling assembly including a retraction assembly selectively couplable to the drive mechanism such that rotation of the drive coupling assembly about a longitudinal axis defined by the surgical device adapter and relative to the housing actuates the drive mechanism.

A coupler assembly is provided for coupling components in a power transmission system, such as a rack and pinion drive system. The coupler assembly includes a floating mount and a pair of clamp members movable between an unfastened configuration in which the floating mount is adjustably supported between the clamp members and a fastened configuration in which the floating mount is fixedly secured between the clamp members. At least a pitch and a yaw of the floating mount are adjustable when the clamp members are in the unfastened configuration. Methods and systems which relate to or include the aforementioned coupler assembly are also provided.

A steering mechanism may comprise an actuation system for one-fingered operation by a user, the system configured to move at least a distal portion of the medical device such that 360 degree articulation is achievable, and a housing coupled to the system, the housing having proximal and distal ends. The system may comprise a first lever rotatable about a first axis, the first lever coupled to a first cam and configured to move the first cam from a first position to a second position when rotated about the first axis to deflect the distal portion; and a second lever rotatable about a second axis, the second lever coupled to a second cam and configured to move the second cam from a first position to a second position when rotated about the second axis to deflect the distal portion, wherein the first lever is coupled to the second lever.

An electronic governor system includes a motor, a transmission coupled to the motor, a throttle plate coupled to the transmission, the throttle plate movable to multiple positions between closed and wide-open, wherein power is supplied to the motor to move the throttle pate to a desired position and wherein power is not supplied to the motor to maintain the throttle plate in the desired position.

A blind riveting apparatus (1) comprises a motor (3), and a clamp (31) for gripping the mandrel of a blind rivet, the clamp being movable substantially along the axis of the rivet. The apparatus further comprises a first transmission (51) configured to transfer rotary motion of the motor (3) to the clamp (31) when engaged; and a second transmission (52) configured to convert rotary motion of the motor (3) to linear motion of the clamp (31), and thereby retract the clamp (31) to pull on the mandrel, when engaged. A transmission control apparatus is arranged to selectively adjust the degree of engagement of at least one of the first (51) and second (52) transmissions, the transmission control apparatus comprising a variable-influence brake or clutch (58). Methods of blind riveting, and further pieces of blind riveting apparatus, are also disclosed.

A drive mechanism for a medication delivery device is presented having a housing, a rotation member that rotates in a first direction with respect to the housing during setting of a dose of a medication and rotates in a second direction with respect to the housing during delivery of the dose, the second direction being opposite to the first direction. The device also has a piston rod that is displaced in a distal direction with respect to the housing for delivering the dose, a drive member which follows rotational movement of the rotation member in the second direction during delivery of the dose, and a stop member which prevents rotational movement of the drive member with respect to the housing in the first direction during setting of the dose.
