ABSTRACT:
Speculum apparatus for use in connection with gynecological endoscopy examination includes a first substantially L-shaped inner member defined by an elongate first handle portion, a first dilating portion extending angularly with respect to said first handle portion, and a first connecting portion integrally interconnecting the first handle and dilating portions, and a second substantially L-shaped outer member defined by an elongate second handle portion, a second dilating portion extending angularly with respect to said second handle portion, and a second connecting portion integrally interconnecting said second handle and dilating portions. The connecting portion of the outer member is received within the channel shaped interior of the first connecting portion and shoulders defined on the second dilating portion engagingly mate with terminal edges of wall portions provided on the first connecting portion so as to provide a detachable pivotal interconnection between the inner and outer members. An aperture is provided in the outer member connecting portion to provide a direct line of sight between the first and second dilating portions of the apparatus. The inner member preferably comprises a conventional unitary or one-part speculum so that upon detachment of the inner and outer members, the inner member may be used as such.
