Abstract

Abstract A fracture alignment device comprising two clamps adjustably and pivotally mounted on a lever which may be rotated as a second class lever to apply pressure on the bone segments to align the bone segments. The device is both autoclavable and radiolucent, whereby the user may monitor the alignment by means of an X-ray machine, and the device may be used in the operating room.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 87 words
A fracture alignment device comprising: a lever means having a n outer limb clamp support means pivotally mounted thereon intermediate the ends of said lever means; an outer limb clamp means pivotally mounted on said outer limb clamp support means; an inner limb clamp means pivotally mounted at one end of said lever means; and a handle means provided at a second end of said lever means; whereby said lever means may be manually rotated as a second class lever to align bone fractures of large bones.
Claim 2
Dependent Claim 87 words
A fracture alignment device comprising: a lever means having a n outer limb clamp support means pivotally mounted thereon intermediate the ends of said lever means; an outer limb clamp means pivotally mounted on said outer limb clamp support means; an inner limb clamp means pivotally mounted at one end of said lever means; and a handle means provided at a second end of said lever means; whereby said lever means may be manually rotated as a second class lever to align bone fractures of large bones.
Claim 3
Dependent Claim 28 words
A fracture alignment device as in claim 1 wherein the device is formed of radiolucent materials, whereby the alignment of bone fractures may be monitored by the user.
Claim 4
Dependent Claim 16 words
A fracture alignment device as in claim 1 wherein the device is both autoclavable and radiolucent.
Claim 5
Dependent Claim 50 words
A fracture alignment device as in claim 1, further comprising adjustment means in both the lever means and the outer limb clamp support means, whereby the outer limb clamp means is adjustable both parallel to and transversely of the lever means, to thereby adjust the device to different size limbs.
Claim 6
Dependent Claim 141 words
A fracture alignment device as in claim 1, further comprising: a plurality of adjustment holes in said lever means; said outer limb clamp support means comprising a bracket pivotally supported by a pivot bolt in one of said plurality of adjustment holes in said lever means, a bracket arm integral with but offset from said bracket, said bracket arm including a plurality of adjustment holes therein, an L-shaped clamp support adjustably mounted on said bracket arm by means of a bolt in one of said plurality of adjustment holes in said bracket arm, said L-shaped clamp support having hinge means thereon for pivotally supporting said outer limb clamp means; and an inner limb clamp bracket mounted at said one end of said lever means, said inner limb clamp bracket having hinge means thereon for pivotally mounting said inner limb clamp means.
Claim 7
Dependent Claim 48 words
A fracture alignment device as in claim 1, further comprising a leverage grip means mounted on said lever means between said outer limb clamp support means and said one end of said lever means, said leverage grip means enabling the lever means to be firmly grasped and rotated.
