A uterine manipulator includes a cervical cup assembly having a cervical cup with an adjustable diameter to facilitate use of the uterine manipulator with patients having a wide range of cervical sizes. In embodiments, the cervical cup is formed from a plurality of slats that are connected to a base member by a living hinge. An actuator is positioned in relation to the cervical cup to move the slats towards or away from adjacent slats to vary the diameter of the cervical cup.

Surgical end effectors

An end effector (2700) for use with a surgical device, the end effector (2700) comprising a drive assembly (2710), a needle assembly (2720) disposed in mechanical cooperation with the drive assembly (2710), wherein rotation of the drive assembly (2710) in a first direction causes a corresponding rotation of the needle assembly (2720), the needle assembly (2720) including a pin (2726), a helix assembly (2740) disposed in mechanical cooperation with the needle assembly (2720), the helix assembly (2740) including a proximal end and a longitudinal slot (2742) and a biasing element (2730) disposed in mechanical cooperation with the needle assembly (2720) and configured to bias the needle assembly (2720) distally with respect to the drive assembly (2710); wherein the needle assembly (2720) is movable with respect to the helix assembly (2740) from a first position where the pin (2726) is out of alignment with the longitudinal slot (2742) of the helix assembly (2740), to a second position where the pin (2726) is aligned with the longitudinal slot (2742) of the helix assembly (2740), to a third position where the pin (2726) has been distally translated with respect to the helix assembly (2740).

Cam-actuated medical puncturing device and method

The medical puncturing device includes a housing, a shield, and a skin puncturing assembly disposed within the housing. The shield is axially movable in the housing. The skin puncturing assembly includes a movable carrier and a skin puncturing element mounted to the carrier. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed. The carrier is maintained in the retracted position by engagement of flexure members or a retaining tab with the carrier. A drive spring is provided to move the carrier from the retracted position to the puncturing position. A retraction spring is provided to return the carrier and skin puncturing element into the housing.
