Uterine manipulator with locking mechanism

Claim 2

In a uterine manipulating device having an elongated frame presenting a longitudinal axis and having a remote end and a proximate end, at least one connecting member received within said frame, a tip mount shiftably carried at the remote end of the frame actuatably connected to said connecting member for shiftable moving an elongated uterine manipulating member thereon within a plane oriented substantially perpendicular to said longitudinal axis, and a graspable handle tip mount to said frame and operatively connected to said tip mount by said connecting member, said handle being mounted for pivotal movement about a pivot axis transverse to said longitudinal axis and substantially parallel to said plane, wherein the improvement comprises a locking member including a latch member pivotally mounted to one of said handle and said frame adjacent the proximate end of said frame for direct locking engagement with the other of said handle and said frame for thereby selectively locking said handle relative to said frame and for correspondingly maintaining said tip mount in a desired, shifted orientation, said locking member further including a spring for biasing the latch member into direct locking engagement with a selected one of a plurality of recesses defined in the other of said handle and said frame.

Claim 3

In a uterine manipulating device having an elongated frame presenting a longitudinal axis and having a remote end and a proximate end, at least one connecting member received within said frame, a tip mount shiftably carried at the remote end of the frame actuatably connected to said connecting member for shiftable moving an elongated uterine manipulating member thereon within a plane oriented substantially perpendicular to said longitudinal axis, and a graspable handle mounted to said frame and operatively connected to said tip mount by said connecting member, said handle being mounted for pivotal movement about a pivot axis transverse to said longitudinal axis and substantially parallel to said plane, wherein the improvement comprises: a locking member pivotally mounted to said handle adjacent the proximate end of said frame for direct locking engagement with said frame, said locking member including a latch member pivotally mounted to said handle, said latch presenting a boss located proximate said frame and a leg for receiving a human digit thereon, said locking member further comprising a pivot pin pivotally mounting said latch member to said handle, said locking member further including a spring biasing said boss into direct locking engagement with said frame and a plurality of circumferentially spaced slots on said frame complementally configured to receive said boss in locking engagement therewith.

Claim 4

In a uterine manipulating device having an elongated frame presenting a longitudinal axis and having a remote end and a proximate end, at least one connecting member received within said frame, a tip mount shiftably carried at the remote end of the frame actuatably connected to said connecting member for shiftable moving an elongated uterine manipulating member thereon within a plane oriented substantially perpendicular to said longitudinal axis, and a graspable handle mounted to said frame and operatively connected to said tip mount by said connecting member, said handle being mounted for pivotal movement about a pivot axis transverse to said longitudinal axis and substantially parallel to said plane, wherein the improvement comprises: a locking member pivotally mounted to said handle adjacent the proximate end of said frame for direct locking engagement with said frame, said locking member including a latch member pivotally mounted to said handle, said latch presenting a boss located proximate said frame and a leg for receiving a human digit thereon, said locking member further comprising a pivot pin pivotally mounting said latch member to said handle, said locking member further including a spring biasing said boss into direct locking engagement with said frame and a plurality of circumferentially spaced slots on said frame complementally configured to receive said boss in locking engagement therewith.
