1. A device for repairing a bone fracture, comprising:
at least two support bars hingedly connected; a lever bar hingedly connected to one of said at least two support bars, said lever bar being a pawl in communication with a plurality of ratchet like teeth disposed along one of said at least two support bars opposite said lever bar thereby forming a pawl and ratchet type mechanism for ratcheting open said at least two support bars; an elongate base adapted to be held in a human hand, said elongate base having a hollow interior; an elongate support rod having a proximal end attached to said elongate base and having a distal end that extends distally of said elongate base and is detachably connected to said at least two support bars; an elongate control rod having a proximal end slideably disposed in said hollow interior of said elongate base and having a distal end that extends distally of said elongate base and is detachably connected to said lever bar; a control knob connected to said elongate control rod, said control knob being slideably mounted on said elongate base for controlling the instantaneous position of said elongate control rod; an elongate control slot formed in said elongate base, said elongate control rod being connected to said control knob through said elongate control slot; said control knob and said elongate control rod having a first position where said at least two support bars and said lever are in a collapsed repose position; said control knob and said elongate control rod having a second position where said at least two support bars and said lever form a triangular support structure; and said elongate support rod having a respective fixed position unaffected by retraction and extension of said control knob and said elongate control rod.
