The invention provides a kind of novel orthopaedics fixed mount that resets, there are two fixed underpans (1) (3) and two ends and be hinged on respectively 6 support bars (2) that its effective length on two fixed underpans (1) (3) can be regulated, each support bar (2) and angled connection of two fixed underpans (1) (3), it is characterized in that, every support bar (2) comprises a sleeve pipe (4) and is inserted into the slide bar (5) in sleeve pipe (4), one end of sleeve pipe (4) is with external screw thread, coordinate the end that ball pivot (5) is arranged on to sleeve pipe (4) by the pressure cap with female thread (7), be connected with respectively lock screw (6) on above-mentioned ball pivot (5), wherein, lock screw (6) comprises an independent nail tail and a nail bar, by lock screw, described ball pivot (5) is connected on fixed underpan (1) (3), thereby make sleeve pipe (4) and fixed underpan (1) (3) hinged.
Preferably, the another end of sleeve pipe (4) is with the clamping head (9) that slide bar (5) can be blocked, and clamping head (9) rear portion is threaded connection locking nut (11) is installed.
Preferably, with external screw thread, coordinate the end that ball pivot (14) is arranged on to slide bar (5) in the outer end of slide bar (5) by the pressure cap with female thread (16).
Preferably, said clamping head (9) is with certain taper, vertically upper with several breach (10).
Preferably, with at least one axial fin (18), inboard with the chute (19) coordinated with this fin (18) at clamping head (9) on slide bar (5) surface.
Preferably, fixed underpan (1) (3) is toroidal.
Preferably, described independent nail tail is tubular.
Preferably, described independent nail tail inwall one end is provided with screw thread and is complementary and is connected with the outside screw of nail bar afterbody, and other end inwall is provided with as hexagon or quincunx.
Preferably, the screwed hole that the independent nail tail outside is provided with screw thread and fixed underpan 1 is complementary, and described nail bar is provided with interior hex slot or Flos Mume groove with independent nail tail link.
The present invention regulates the rotation of the screw rod of prior art support bar to be improved to the slide bar telescopic adjustment, the active exercise of support bar is changed into to the passive exercise driven by chassis, according to the bone stump para-position, need to compress prolongation, the left and right angulation, the front and back angulation, the left and right translation, the front and back translation, six actions such as rotation, to behind good position, the locking nut spin locking on every support bar being got final product, without computer, calculate, accurate positioning, easy and simple to handle, fixation is reliable, the any hospital that can do fracture fixing operation all can be used this product, be convenient to the penetration and promotion in China, accelerating bone healing, alleviate patient's misery.
