Abstract: A speculum insertable into a body cavity of a person including a support member having an opening, provided with elongated arm sections each disposed in a plane including a centerline of such opening, blade members each lying in the plane of an arm section and having an intermediate section pivotally connected to the support member, a first end section displaceable into and out of engagement with the end section of another blade member and a second end section displaceable relative to one of the arm sections, means for releaseably biasing the first end sections of the blade members into engagement, permitting such end sections to be inserted into and removed from a body cavity, and means mounted on each arm member, engageable by a second end section of a blade member, for caroming such blade member to pivot about the axis thereof.

Abstract: A speculum for the insertion and expanding of a body cavity. The speculum comprises a plurality of blades pivotally connected around a ring-shaped frame, the first ends thereof extending longitudinally and meeting at a point distant from the frame to form a generally bulbous end and the second ends which are manipulated to rotate the blades about the frame. A rotating action of the second ends causes the first ends to angularly move away from each other to expand the bulbous end, and hence the body cavity. A series of block pivotally attached to the frame interact with the second ends to form a ratcheting locking means to lock the blades at certain positions between a closed position and an open position.

Abstract: A surgical instrument for obtaining biopsies, performing microsurgery and bipolar microelectrocautery. The instrument head includes opposing jaw members which open and close during the operating procedures. The angle of the instrument head relative to the instrument frame is adjustable to effectively operate on varying surfaces. The angle can be continuously adjusted while the instrument is in an operating position.

Abstract: A surgical pad adapted for use with a speculum blade insertable into the vaginal cavity of a patient, in performing a dilation a curettage procedure, generally comprising a pad disposable on the speculum blade for collecting curetted tissue, the pad having straps or an adhesive section on the underside thereof for securing the pad on the speculum blade to facilitate insertion of the pad on the speculum blade into the vaginal cavity and to prevent displacement of the pad relative to the speculum blade when performing curettage of the uterine canal. The periphery of the upper side of the pad is provided with an adhesive surface area covered by a removable strip which may be removed after curetted tissue has been collected on the pad to permit the pad to be folded onto itself and adhesively secured together to enclose the curetted tissue.

Abstract: A surgical instrument for performing gynecological procedures comprising a first forceps lever having a forwardly disposed section insertable into a vaginal cavity, an intermediate section and a rearwardly disposed handle section, a second forceps lever having a forwardly disposed section insertable into a vaginal cavity with the insertable section of the first forceps lever, an intermediate section pivotally connected to the intermediate section of the first forceps lever and a rearwardly disposed handle section cooperable with a handle section of the first forceps lever, the insertable section of the first forceps lever having a longitudinally disposed bore, a plunger member disposed in the longitudinally disposed bore and displaceable longitudinally therein, such plunger member being insertable in the uterine canal when the insertable sections of the forceps levers are inserted into a vaginal cavity, flexible material disposed on the plunger member and expandable to engage the wall of the uterine cavity an
