Abstract
Abstract The proposed apparatus for drawing together and fixing the pelvic halves on pubic symphysis ruptures comprises a U-shaped frame whereof the ends carry elastic members designated to cooperate with the patient's body. The elastic members are rotatably mounted and adapted to move toward each other. The elastic members are moved toward each other and caused to exert a required compressive force on the patient's body by means of servos coupled to a power source.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
An apparatus for drawing together and fixing the pelvic halves in pubic symphysis ruptures, which comprises: a U-shaped frame; supports whereon said frame is mounted; two elastic members designed to cooperate with the patient's body which are disposed on the ends of said frame and are adapted to move toward each other as well as turn about an axis parallel to the direction of said counter motion; servos coupled to said elastic members which provide for said counter motion of said elastic members and cause the latter to exert a desired compressive effort on the patient's body for a specified length of time; and a power source coupled to said servos.
Claim 2
Independent Claim
111 words
An apparatus for drawing together and fixing the pelvic halves in pubic symphysis ruptures, which comprises: a U-shaped frame; supports whereon said frame is mounted; two elastic members designed to cooperate with the patient's body which are disposed on the ends of said frame and are adapted to move toward each other as well as turn about an axis parallel to the direction of said counter motion; servos coupled to said elastic members which provide for said counter motion of said elastic members and cause the latter to exert a desired compressive effort on the patient's body for a specified length of time; and a power source coupled to said servos.
Claim 3
Dependent Claim
94 words
An apparatus as set forth in claim 1, which comprises: a plurality of sleeves disposed coaxially a certain distance one from another and capable of executing a limited longitudinal motion one with respect to another, the outer sleeve being fastened to said elastic member; a bellows serving as said servo which is disposed inside the inner one of said sleeves and attached at one end to said elastic member; and a cylindrical hinge coaxial with respect to said sleeves which connects the other end of said bellows and said inner sleeve with said frame.
Claim 4
Dependent Claim
31 words
An apparatus as set forth in claim 1, wherein said U-shaped frame is composed of side arms constructed as extensible members and a cross arm likewise constructed as an extensible member.
Claim 5
Dependent Claim
31 words
An apparatus as set forth in claim 2, wherein said U-shaped frame is composed of side arms constructed as extensible members and a cross arm likewise constructed as an extensible member.
Claim 6
Dependent Claim
39 words
An apparatus as set forth in claim 1, which comprises: inner chambers formed in said elastic members and alternately interconnected to form several groups; and a pressure source for alternately supplying compressed air to said groups of said chambers.
Claim 7
Dependent Claim
39 words
An apparatus as set forth in claim 2, which comprises: inner chambers formed in said elastic members and alternately interconnected to form several groups; and a pressure source for alternately supplying compressed air into said groups of said chambers.
Claim 8
Dependent Claim
39 words
An apparatus as set forth in claim 3, which comprises: inner chambers formed in said elastic members and alternately interconnected to form several groups; and a pressure source for alternately supplying compressed air into said groups of said chambers.
