Abstract A triangular base member fits between the flexed thighs and bears downward against the suprapubic area of the lowest part of the abdomen. An adjustable angular extension on the base member has a downturned end portion adjustably connected with an upturned end portion of an L-shaped retractor blade. The blade has a horizontal insertable portion which presses upwardly against the vaginal wall giving the surgeon exposure and operating space and at the same time protecting the urethra and urinary bladder. The inserted portion of the blade underlies the base member and operates in the manner of a clamp wherein the downward pressure exerted exteriorly against the abdomen by the base member applies an upward pressure to the retractor blade. The anterior retractor is used in conjunction with a conventional weighted lower or posterior retractor.
An anterior vaginal retractor comprising a generally triangular base member adapted to fit between the thighs of a patient, when the thighs are flexed forward toward the patient''s head, and bear against the superapubic area of the lowest part of the abdomen, a malleable and resilient L-shaped extension arm adapted for positioning between the patient''s thighs, an adjustable length connection between one end of said arm and the apex of said triangular base member, an L-shaped blade member having one end adapted to be inserted into the vagina of said patient and an exterior end adapted for positioning between the patient''s thighs and overlapping the other end of said extension arm, and an adjustable length connection between the overlapping parts of said extension arm and blade member.

An anterior vaginal retractor comprising a generally triangular base member adapted to fit between the thighs of a patient, when the thighs are flexed forward toward the patient''s head, and bear against the superapubic area of the lowest part of the abdomen, a malleable and resilient L-shaped extension arm adapted for positioning between the patient''s thighs, an adjustable length connection between one end of said arm and the apex of said triangular base member, an L-shaped blade member having one end adapted to be inserted into the vagina of said patient and an exterior end adapted for positioning between the patient''s thighs and overlapping the other end of said extension arm, and an adjustable length connection between the overlapping parts of said extension arm and blade member.
Claim 3
Dependent Claim
