Abstract
Abstract A wire fixing device, for fixing wire in orthopedic surgery or other circumstances by controlled twisting together of the free end portions of the wire, comprises an elongate screw, a nut for engagement with the screw and having means for securing the free end portions of a wire to be fixed, a guide member with two passageways for the wire free end portions, and at least one slide member which extends from the guide member for longitudinal slidable engagement relative to and rotation with the nut. In use of the device the wire free ends are passed through the guide member passageways and secured with the nut, and the screw is screwed through the nut to draw this from the guide member and tense the wire. Then, the nut is screwed towards the guide member to twist the wire while feeding wire into the twist in a controlled manner to avoid breakage through excess tension buildup.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A wire fixing device comprising: an elongate screw member; grip means connected with said screw member to facilitate rotation thereof; a nut threadably engaged with said screw member; means coupled with said nut for securing therewith the free end portions of a wire to be fixed; a wire guide member located adjacent the other end of said screw member from said grip means, and having two passageways therethrough generally in the longitudinal axial direction of said screw member for receipt of said wire free end portions to pass to said nut and securing means; and at least one elongate slide member connected at one end thereof to said guide member and extending therefrom alongside said screw member to said nut, said slide member being engaged with said nut for rotation therewith and sliding relative thereto in the longitudinal axial direction of said screw member.
Claim 2
Dependent Claim
144 words
A wire fixing device comprising: an elongate screw member; grip means connected with said screw member to facilitate rotation thereof; a nut threadably engaged with said screw member; means coupled with said nut for securing therewith the free end portions of a wire to be fixed; a wire guide member located adjacent the other end of said screw member from said grip means, and having two passageways therethrough generally in the longitudinal axial direction of said screw member for receipt of said wire free end portions to pass to said nut and securing means; and at least one elongate slide member connected at one end thereof to said guide member and extending therefrom alongside said screw member to said nut, said slide member being engaged with said nut for rotation therewith and sliding relative thereto in the longitudinal axial direction of said screw member.
Claim 3
Dependent Claim
29 words
A device according to claim 1 wherein said two passageways are located in said guide member in diametrically opposed manner relative to the longitudinal axis of said screw member.
Claim 4
Dependent Claim
29 words
A device according to claim 2 comprising two of said slide members located in quadrature relationship with said two passageways relative to the longitudinal axis of said screw member.
Claim 5
Dependent Claim
