Abstract
Abstract A combination of disposable medical instruments is provided which can be used when performing an abortion including a speculum comprising metal jaw members and disposable plastic tip members. The plastic tip members are fitted on the jaw members in snap-fit relationship and are shaped so that they adequately expose the cervix and tend to bring it forward toward the vaginal opening. A disposable currette or cannula for a suction aspirator is also provided and comprises a tube of plastic material which is sufficiently flexible to permit relatively easy bending of the tube during use and yet sufficiently rigid to maintain the desired tubular configuration during such bending. The tube is provided at its operative end with a pair of holes on opposite sides thereof, each of a size sufficient to pass the embryonic tissue therethrough.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
A speculum comprising: a pair of jaw members; handle means for supporting and moving said jaw members between a closed position wherein they are in substantial abutment and an open position wherein they are spaced apart; stop means for holding said jaw members in an open position; and a pair of semirigid resiliently bendable speculum tip members with a tip member mounted on each jaw member and with the outer surfaces of said tip members defining a generally circular outlne when in the open position and with a zone of relatively great width adjacent the ends thereof and a narrow neck portion inwardly of said ends, said members being so dimensioned that said zone of greater width may be positioned at the central portion of the vagina and said neck portion positioned at the vaginal opening whereby moving said jaw members to said open position causes lateral vaulting of said central portion with resilient bending of said tip members and the cervix of the uterus is thereby moved toward the vaginal opening.
Claim 2
Dependent Claim
172 words
A speculum comprising: a pair of jaw members; handle means for supporting and moving said jaw members between a closed position wherein they are in substantial abutment and an open position wherein they are spaced apart; stop means for holding said jaw members in an open position; and a pair of semirigid resiliently bendable speculum tip members with a tip member mounted on each jaw member and with the outer surfaces of said tip members defining a generally circular outlne when in the open position and with a zone of relatively great width adjacent the ends thereof and a narrow neck portion inwardly of said ends, said members being so dimensioned that said zone of greater width may be positioned at the central portion of the vagina and said neck portion positioned at the vaginal opening whereby moving said jaw members to said open position causes lateral vaulting of said central portion with resilient bending of said tip members and the cervix of the uterus is thereby moved toward the vaginal opening.
Claim 3
Dependent Claim
32 words
A speculum as defined in claim 1 wherein the zone of greater width and zone of reduced width of said tip members have a generally spherical configuration when in the closed position.
Claim 4
Dependent Claim
20 words
A speculum as defined in claim 1 wherein the ends of each of said tip members has a semicircular section.
Claim 5
Dependent Claim
18 words
A speculum as defined in claim 1 wherein said semirigid tip members are resiliently bendable throughout their length.
Claim 6
Dependent Claim
20 words
A speculum as defined in claim 1 wherein said semirigid tip members are resiliently bendable at said narrow neck portion.
Claim 7
Dependent Claim
33 words
A speculum as defined in claim 1 wherein said tip members when in said closed position have a circular cross section in a plane perpendicular to the longitudinal axis of the tip members.
Claim 8
Dependent Claim
25 words
A speculum as defined in claim 1 wherein said tip members have closed sides in the planes generally parallel to the planes of jaw movement.
Claim 9
Dependent Claim
14 words
A speculum as defined in claim 1 wherein said tip members have open sides.
