Patent ID: 7749162

Claim:
A vaginal speculum arrangement comprising: a blade system for opening the vagina, the blade system having a first blade and a second blade positionable relative to each other in a plurality of non-zero angles and along a longitudinal symmetry axis between a distal portion and a proximate portion of each of the first and second blades, said first blade and second blade connected to each other by a pivoting joint located at the rear of the blades, and an injection mechanism for dispensing a diagnostic marker onto a surface of examined tissue, the injection mechanism having an injection probe having a longitudinal axis, a marker container and an injector for enabling injection of the marker, wherein the non-zero angle between the longitudinal axis of the injection probe and the longitudinal symmetry axis of the blade system remains substantially constant for each of the plurality of angles between the first and second blades, a cross section of the injection probe having dimensions that are substantially smaller than dimensions of a cross section of a rear aperture of the blade system, and wherein the injection probe allows for a substantially homogeneous application of the marker on a desired area of the examined tissue, irrespectively from an opening angle of the first and second blades and allows for observation of the desired area through the rear aperture of the blade system, before, during, and after the injection of the marker.
