Abstract
Abstract An apparatus, comprising a supporting and a rotatable stirrup together with respective wire spokes, intended for being drawn through juxtapositional bones and joints, forms two rigid systems. Said rigid systems are joined together by means of distractors with hinge joint fastenings, situated at the two ends of the wire spoke of the supporting stirrup. The position of the fulcrums of the hinge joints determines the position of the apparatus' axis of rotation. A special regulator is provided for adjusting the position of the axis of rotation of the apparatus which comprises a means for rotating the fulcrum of the hinge joint fastening the distractors and a means for moving the fulcrums of the hinge joints along the distractors connecting the supporting and rotatable stirrups.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
An apparatus for the surgical treatment of bones and joints, comprising at least a supporting and a rotatable stirrups, wire spokes secured in said stirrups and intended for being drawn through juxtapositional segments of bones or joints, said rotatable stirrup and the spokes associated therewith forming a rigid system, while said supporting stirrup and the spokes associated therewith form another rigid system, distractors intended to interconnect said rigid systems, hinge joint fastenings of said distractors, situated at the two ends of the wire spoke of the supporting stirrup, the position of the axis of said hinge joint fastenings determining that of the axis of rotation of the apparatus, and a regulator of the position of the apparatus' axis of rotation, including a means for rotating the fulcrum of the hinge joint fastening of the distractors along a circumference relative to the axis of the wire spoke of said supporting stirrup, as well as a means for moving the fulcrums of the hinge joints along the distractors interconnecting said supporting and rotatable stirrups.
Claim 2
Independent Claim
172 words
An apparatus for the surgical treatment of bones and joints, comprising at least a supporting and a rotatable stirrups, wire spokes secured in said stirrups and intended for being drawn through juxtapositional segments of bones or joints, said rotatable stirrup and the spokes associated therewith forming a rigid system, while said supporting stirrup and the spokes associated therewith form another rigid system, distractors intended to interconnect said rigid systems, hinge joint fastenings of said distractors, situated at the two ends of the wire spoke of the supporting stirrup, the position of the axis of said hinge joint fastenings determining that of the axis of rotation of the apparatus, and a regulator of the position of the apparatus' axis of rotation, including a means for rotating the fulcrum of the hinge joint fastening of the distractors along a circumference relative to the axis of the wire spoke of said supporting stirrup, as well as a means for moving the fulcrums of the hinge joints along the distractors interconnecting said supporting and rotatable stirrups.
Claim 3
Dependent Claim
68 words
An apparatus as claimed in claim 1, wherein the means for rotating the hinge joint fulcrum is formed by a rotatable pin whose axis of rotation is parallel to the axis of the wire spoke of the supporting stirrup and which carries the fulcrum of the hinge joint, with guide slots being provided for the pin to move along the axis of the distractor interconnecting the rigid systems.
Claim 4
Dependent Claim
37 words
An apparatus as claimed in claim 2, wherein the pin has a head made flush with a disc rigidly connected with said pin and provided with an aperture for fitting therein the fulcrum of the hinge joint.
Claim 5
Dependent Claim
42 words
An apparatus as claimed in claim 2, wherein rigidly connected with said pin is a rod situated in the same plane with the distractor interconnecting the supporting and rotatable stirrups, with the fulcrum of the hinge joint being secured on said rod.
Claim 6
Dependent Claim
55 words
An apparatus as claimed in claim 2, wherein connected with said pin is a lead screw for moving said pin in the guide slots along the distractor interconnecting the supporting and rotatable stirrups of the rigid systems, with a screw and lever-type clamp being provided for securing the pin in the desired position after movement.
Claim 7
Dependent Claim
56 words
An apparatus as claimed in claim 3, wherein said disc has several holes arranged at different radial distances from the pin's axis of rotation and serving to alter the radius of the rotation of the hinge joint fulcrum relative to the wire spoke in conformity with the radius of the surfaces of the segments being juxtaposed.
Claim 8
Dependent Claim
55 words
An apparatus as claimed in claim 4, wherein said rod has several apertures arranged at different distances from said pin's axis of rotation and serving to alter the radius of the rotation of the hinge joint fulcrum relative to the wire spoke in conformity with the radius of the surfaces of the segments being juxtaposed.
Claim 9
Dependent Claim
94 words
An apparatus as claimed in claim 1, wherein sid regulator of the position of the apparatus' axis of rotation is formed by a circular guide whose center coincides with the axis of the wire spoke of the supporting stirrup, and set in said guide rotatably about its own axis and movably therein is a pin carrying a rod rigidly connected therewith and situtated in the plane of rotation of the distractor interconnecting the supporting and rotatable stirrups, and provided with a hole for setting therein the fulcrum of the hinge joint fastening the distractors.
Claim 10
Dependent Claim
81 words
An apparatus as claimed in claim 1, wherein the regulator of the position of the apparatus' axis of rotation is formed by a circular guide whose center coincides with the axis of the wire spoke of the supporting stirrup, and set in said guide rotatably about its own axis is a pin carrying a rod rigidly connected thereto and provided with an aperture for securing the fulcrum of the hinge joint, while said guide is set rotatably about its own axis.
Claim 11
Dependent Claim
29 words
An apparatus as claimed in claim 9, wherein said rod has a number of holes for setting the pin at different distances from the center of the circular guide.
