Abstract
Abstract A radium applicator for treating cancer of the uterus formed in the shape of a vaginal speculum. The speculum applicator comprises an upper colpostat housing having a pair of pivotable arms connected thereto and a lower retractor blade assembly. A radium-carrying ovoid is connected to each colpostat arm and a linkage is connected to each ovoid for pivoting each ovoid about an axis that is substantially perpendicular to the pivotal axis of its colpostat arm. Means are provided for connecting a radiumcarrying tandem to the colpostat''s saddle handle after the applicator has been inserted in the vagina.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
A radium applicator which comprises: an upper colpostat housing, said colpostat housing including a saddle and a pair of colpostat arms; means for connecting said colpostat arms to said saddle; an ovoid for carrying radium located adjacent to the distal end of each colpostat arm; means for pivotally connecting each said ovoid adjacent to the distal end of each said colpostat arm; means connected to said housing for pivoting each colpostat arm whereby the distal ends of the colpostat arms can be moved apart from each other, and a linkage connected to each ovoid for pivoting each ovoid about an axis that is substantially perpendicular to its colpostat arm pivot axis.
Claim 2
Dependent Claim
111 words
A radium applicator which comprises: an upper colpostat housing, said colpostat housing including a saddle and a pair of colpostat arms; means for connecting said colpostat arms to said saddle; an ovoid for carrying radium located adjacent to the distal end of each colpostat arm; means for pivotally connecting each said ovoid adjacent to the distal end of each said colpostat arm; means connected to said housing for pivoting each colpostat arm whereby the distal ends of the colpostat arms can be moved apart from each other, and a linkage connected to each ovoid for pivoting each ovoid about an axis that is substantially perpendicular to its colpostat arm pivot axis.
Claim 3
Dependent Claim
43 words
A radium applicator as described in claim 1, including a lower blade and means connecting said lower blade to said saddle; and said colpostat housing being positioned over said lower blade, to form a speculum-like instrument thereby providing proper vaginal exposure and retraction.
Claim 4
Dependent Claim
55 words
A radium applicator as described in claim 2, in which said saddle is of a length that is effective to permit it to remain visible outside the vagina, thereby indicating the position and direction of the colpostat and thereby being used to aid in removal of the colpostat housing at the end of the application.
Claim 5
Dependent Claim
91 words
A radium applicator as described in claim 2, wherein said lower blade has a downwardly extending portion at one end thereof adapted for contact by the hand of the operator and a handle adjustably connected to said downwardly extending portion, means connecting said handle to said housing, said handle being Operable to aid in effecting relative movement between said lower blade and said colpostat arms, and means for adjustably connecting said handle and said downwardly extending portion and for retaining said handle and said downwardly extending portion in a selected location.
Claim 6
Dependent Claim
24 words
A radium applicator as described in claim 2, including means for enabling rapid disconnection of said lower blade assembly from said upper colpostat housing.
Claim 7
Dependent Claim
50 words
A radium applicator as described in claim 1, said colpostat housing having means connected thereto for receiving a radium-carrying tandem, and a tandem comprising an elongated rod-shaped member adapted for carrying radium and having means for connecting said tandem to said tandem receiving means after the applicator has been inserted.
Claim 8
Dependent Claim
27 words
A radium applicator as described in claim 6, in which said tandem comprises several connected parts to allow adjustments in length, angle and height of the tandem.
Claim 9
Dependent Claim
193 words
A radium applicator which comprises: an upper colpostat housing, said colpostat housing including a saddle and a pair of colpostat arms; means for connecting said colpostat arms to said saddle; a first shaft connected to one of said arms; a first radium-carrying ovoid; a second shaft connected to the other of said arms; a second radium-carrying ovoid; means for movably positioning said first and second ovoids on said first and second shafts, respectively, with each ovoid being adapted for positioning at the distal end of one of said colpostat arms and at a location under said arms; means connected to said housing for pivoting each colpostat arm whereby the distal ends of the colpostat arms can be moved apart from each other; a lower blade; means connecting said lower blade to said saddle, said colpostat housing being positioned over said lower blade to form a speculum-like instrument; said saddle being of a length that is effective to permit it to remain visible outside the vagina, thereby indicating the position and direction of the colpostat and thereby being used to aid in the removal of the colpostat housing at the end of the application.
Claim 10
Dependent Claim
193 words
A radium applicator which comprises: an upper colpostat housing, said colpostat housing including a saddle and a pair of colpostat arms; means for connecting said colpostat arms to said saddle; a first shaft connected to one of said arms; a first radium-carrying ovoid; a second shaft connected to the other of said arms; a second radium-carrying ovoid; means for movably positioning said first and second ovoids on said first and second shafts, respectively, with each ovoid being adapted for positioning at the distal end of one of said colpostat arms and at a location under said arms; means connected to said housing for pivoting each colpostat arm whereby the distal ends of the colpostat arms can be moved apart from each other; a lower blade; means connecting said lower blade to said saddle, said colpostat housing being positioned over said lower blade to form a speculum-like instrument; said saddle being of a length that is effective to permit it to remain visible outside the vagina, thereby indicating the position and direction of the colpostat and thereby being used to aid in the removal of the colpostat housing at the end of the application.
