Abstract
Abstract A uterine controlling forceps particularly useful for manipulation of the soft post-abortal or post-partum uterus during laparoscopic sterilization consists of a pair of tips gently curved to rise about 90* to parallel side-by-side shank portions, a pair of generally rectilinear handle members extending from the shank portions at an angle of about 20* and diverging when the tips are closed an amount at least as great as the maximum divergence desired at the tips, a hinge connecting said handle portions with the pivotal axis thereof parallel to and generally axially aligned with the longitudinal axes of the shank portions and a spring normally urging the tips of the forceps into the open position.

Claim 1
Independent Claim
203 words
Forceps comprising a pair of parallel side-by-side shank portions, end portions extending from one end of each of the shank portions and terminating in tip portions, said end portions gently curved to rise about 90* such that said tip portions a plane which intersects the longitudinal axes of said shank portions and to flare outwardly from about 2 to 4 cEntimeters in respect to said plane, a handle portion extending from the other end of each of the shank portions and curved downwardly at an angle of about 20* in respect to said plane and in the opposite direction to the direction of curvature of said end portions and flared outwardly in respect to said plane when the end portions are together an amount at least as great as the maximum divergence at the end portions and in abutting side-by-side relation when the end portions are divergent, a hinge connecting said handle portions with the pivotal axis of the hinge being parallel to and generally axially aligned with the longitudinal axes of the shank portions and lying along said plane which intersects the longitudinal axes of the shank portions, and a spring normally urging said handle portions into the closed abutting side-by-side position.
