As shown in figures 1-3, a tibial plateau collapse fracture restorer comprises a handle 1, the handle 1 is connected with a restoration head 4 through a connecting rod piece, the thickness of the restoration head 4 is 2-3mm, and the restoration head 4 can support a collapsed bone block to jack the collapsed bone block for restoration after entering the deep position of the collapsed bone block along a fracture gap.

Among the prior art, to the operation that resets that platform bone piece sinks, need just can raise the fracture piece of caving in under the articular surface to the interior (outside) side condyle of platform cleft, the wound is big, but the bone piece that sinks often accompanies the condyle crack simultaneously and exists, and the crack size is only 2-3mm usually moreover, based on this, the utility model provides a tibial plateau sinks the fracture restorer and adopts the structural style of handle connection reset head, and in the operation, reset head 4 supports the bone piece that sinks behind the bone piece depths of caving in along the condyle crack entering and jacks up it, accomplishes the work of resetting to avoided opening the very big operation wound that platform condyle portion caused, need not bore the hole more than about 10mm in platform condyle portion, operation efficiency also is showing simultaneously and is improving. Since the crack is only 2-3mm, in order to ensure that the reset head 4 smoothly enters the crack, the thickness of the reset head 4 is also 2-3mm and is slightly smaller than the size of the crack.

In a preferred embodiment, the connecting rod comprises an extension rod 2 and a bent rod 3, the handle 1 is sequentially connected with the extension rod 2 and the bent rod 3, the reset head 4 is connected with the end part of the bent rod 3, the cross section size of the reset head 4 is larger than that of the bent rod 3, and the reset head 4 and the extension rod 2 are not in the same plane and are arranged in parallel. The angle between the extension rod and the bent rod is 135 deg..

In order to facilitate the reset head 4 to enter a fracture gap and support a collapsed bone block, a good rod piece for supporting and supporting is arranged between the handle 1 and the reset head 4, namely, a connecting rod piece is adopted and comprises an extension rod 2 and a bent rod 3, the length of the extension rod 2 is proper within 80-120mm and is away from an operation wound surface by a certain distance, the connecting rod piece is reasonably arranged according to the use condition of an operator, the bent rod 3 is an arc-shaped rod piece, the two ends of the bent rod are respectively connected with the reset head 4 and the extension rod 2, the bent rod 3 is convenient for controlling the reset head 4 to enter the collapsed bone block to control the angle, and the operation is flexible.

In a preferred embodiment, the reduction head 4 is oval flat with a width of 8mm or 10 mm. Because the fracture gap generally takes place at the edge, get into the bone piece below that sinks back along the fracture gap when reduction head 4, need rotate certain angle, make it hold the bone piece after can will sink the bone piece jack-up and reset completely, when handle 1 pivoted, drive extension rod 2, knee 3 and reduction head 4 and rotate simultaneously, the oval platykurtic of reduction head 4, the width has two kinds of specifications, be 8mm or 10mm respectively, thereby guarantee great area can let reduction head 4 stably hold the bone piece that sinks and reset.

In a preferred embodiment, the reduction head 4, the bent rod 3 and the extension rod 2 are all made of stainless steel, and the handle 1 is preferably made of wood, so that the reduction head is not slipped during operation, is easy to sterilize and is convenient to hold.
