Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 205 words
A splint device for the treatment of a fractured leg comprising a base frame, a plurality of traction producing means, first support means having one end joined to said base frame and having the opposite end suspended by means of a first traction producing means to balance said first support means, said first support means being segmented and including two angularly adjustable support legs, relatively short support legs and relatively long support legs, respectively, said relatively short support legs being connected to the base frame by first pivot means and said relatively long support legs being connected with said first traction producing means, second support means articulated with one end to second pivot means provided on said first support means, said second support means being shorter in length than said long support legs of said first support means and being connected with its opposite end to a second traction producing means to balance said second support means, and means to move both said support means centrally, as well as relatively to each other into a position affording displacement of said first support means for engaging the femur independently of said second support means, which is engageable with the tibia-fibula of the leg to be treated.
Claim 2
Dependent Claim 205 words
A splint device for the treatment of a fractured leg comprising a base frame, a plurality of traction producing means, first support means having one end joined to said base frame and having the opposite end suspended by means of a first traction producing means to balance said first support means, said first support means being segmented and including two angularly adjustable support legs, relatively short support legs and relatively long support legs, respectively, said relatively short support legs being connected to the base frame by first pivot means and said relatively long support legs being connected with said first traction producing means, second support means articulated with one end to second pivot means provided on said first support means, said second support means being shorter in length than said long support legs of said first support means and being connected with its opposite end to a second traction producing means to balance said second support means, and means to move both said support means centrally, as well as relatively to each other into a position affording displacement of said first support means for engaging the femur independently of said second support means, which is engageable with the tibia-fibula of the leg to be treated.
Claim 3
Dependent Claim 41 words
A splint device according to claim 1, said moving means including arm means, and a worm-gear mechanism carried by said base frame and operatively connected via said arm meaNs with said first support means to regulate the position of the latter.
Claim 4
Dependent Claim 46 words
A device according to claim 2, said worm gear mechanism including shaft means interconnecting parts of said base frame and carrying said arm means to facilitate adjustment of the support legs of said first support means to each other and to said second support means, respectively.
Claim 5
Dependent Claim 56 words
A splint device according to claim 1, said second support means being equipped with an extension, and two sets of roller means mounted, respectively, on said extension and on said first support means near said second pivot means, said roller means accommodating a cable connection between a further traction producing means and said first support means.
Claim 6
Dependent Claim 63 words
A device according to claim 4, one set of said roller means including friction-reducing means located adjacent said second pivot means and carried by said first support means, said cable connection having one end attached to an extension yoke positionable with said tibia-fibula on said second support means and having another end joined to weight means in the proximity of said friction-reducing means.
Claim 7
Dependent Claim 27 words
A device according to claim 5, including cable guide means affixed to said extension and positioned between said other set of roller means and said extension yoke.
