One big elongated slot hole cross.
The adjustable drawing-off frame 11 is made of the first guide plate 12 and the second guide plate 13, and the two of first guide plate 12
End and the both ends of second guide plate 13 are equipped with guide plate through-hole 16, between the guide plate through-hole 16 at both ends, described the
It is also equipped with length-adjustment holes on one guide plate 12 and second guide plate 13.
In the present embodiment, the length-adjustment holes are preferably an elongated guide plate groove type hole 17.In other embodiment
In, the length-adjustment holes can also be the hole of row's circular hole or other forms.
In the present embodiment, sliding groove structure 15 is equipped between first guide plate, 12 and second guide plate 13, first is oriented to
Plate 12 and the second guide plate 13 are mutually slided by sliding groove structure 15, thus adjust the length of adjustable drawing-off frame 11.Preferably, institute
It is concave-convex dovetail groove to state sliding groove structure 15, wherein the first guide plate 12 is equipped with male dovetail slot, the second guide plate is equipped with
Female dovetail slot adjusts the length of adjustable drawing-off frame 11 with each other as sliding slot.In other embodiments, can also be first to lead
Female dovetail slot is set on plate 12, and male dovetail slot is set on the second guide plate.In addition, sliding groove structure 15 can also select other shapes
The sliding slot of formula.
When the adjustable drawing-off frame 11 is adjusted, unclamps bolt and pay 14, the first guide plate 12 and the second guide plate 13 is mutual
Slid inward is to appropriate length, then pays 14 with bolt and fix；The guide plate through-hole 16 of two guide plate inner ends coincides and uses spiral shell
Bolt is paid 14 and is fixed, and the length of adjustable drawing-off frame 11 is longest at this time.
According to needs are treated, the steel needle fixing clamp 6 and Kirschner wire 7 can be connected to the guide plate of two guide plate outer ends
On through-hole 16, it can also be connected in length-adjustment holes.Adjustable drawing-off frame 11 can fix multiple steel needle fixing clamps 6 and kirschner simultaneously
Needle 7, to meet the drawing-off dynamics to bone block.
The bone block extension apparatus can adjust adjustable drawing-off frame 11 according to treatment needs by bolt pair 14 and length-adjustment holes
Length.
The extension apparatus regulation device 18 includes manual adjusting nut 8, drawing-off threaded adjusting bar 9, is oriented to spindle nose 10 and spiral shell
Bolt pays 14, and the drawing-off threaded adjusting bar 9 is inserted in fixing bracket limiting through hole 4, and the manual adjusting nut 8 is located at manual tune
It in section nut putting hole and is threaded on drawing-off threaded adjusting bar 9, the threaded one end for being oriented to spindle nose 10 is connected to
On wherein one end of drawing-off threaded adjusting bar 9, the other end for being oriented to spindle nose 10 is equipped with U-shaped connection otic placode 10.1, and the bolt is paid
14 pass through U-shaped connection otic placode 10.1 and the first guide plate 12 and the guide plate through-hole 16 on the second guide plate 13 or length tune
Knothole so by adjustable drawing-off frame 11 be connected to be oriented to spindle nose 10 on.
The shape and size phase of the shape and size specification of the fixing bracket limiting through hole 4 and drawing-off threaded adjusting bar 9
It coincide, there is limit and rail effect.The drawing-off threaded adjusting bar 9 is other than screw thread, in corresponding positive and negative in planar,
It can guarantee that 9 meetings of bar of drawing-off threaded adjusting slide axially along fixing bracket limiting through hole 4 in this way, holder limit cannot be relatively fixed
Through-hole 4 rotates.
By rotary manual adjusting nut 8 forward or backwards, drawing-off threaded adjusting bar 9 is in fixing bracket limiting through hole 4
It moves up and down, can thus adjust drawing-off distance.
There is internal thread hole in described one end for being oriented to spindle nose 10, is oriented to spindle nose 10 and passes through internal thread hole and drawing-off threaded adjusting bar
Thus 9 connections can realize that being oriented to spindle nose 10 carries out 360 ° of rotation relative to drawing-off threaded adjusting bar 9, and then make adjustable drawing-off frame
11 carry out 360 ° of rotation relative to drawing-off threaded adjusting bar 9, to ensure adjustment selection drawing-off optimum position.That is, ginseng
See that Fig. 5, Fig. 9, the bone block extension apparatus can adjust adjustable drawing-off frame 11 and drawing-off according to treatment needs by being oriented to spindle nose 10
1 antarafacial of device fixing bracket intersects or antarafacial is vertical.
The other end for being oriented to spindle nose 10 is equipped with U-shaped connection otic placode 10.1, and adjustable drawing-off frame 11 is paid 14 by bolt and connected
Both it is connected in U-shaped connection otic placode 10.1, the angle of adjustable drawing-off frame 11 and extension apparatus fixing bracket 1 can be finely tuned in this way, make
It is relatively parallel or at a certain angle.That is, referring to Fig. 7, the bone block extension apparatus can pass through bolt according to treatment needs
Pay 14 and U-shaped connection otic placode 10.1 adjust the relative angle of adjustable drawing-off frame 11 and extension apparatus fixing bracket 1, both make relatively
It is parallel or at a certain angle.
360 ° of rotation is carried out on drawing-off threaded adjusting bar by being oriented to spindle nose, and finely tunes adjustable drawing-off frame 11 and leads
The angle for stretching device fixing bracket 1, to make bone block extension apparatus be provided with the adjustable feature of multi-angle.
It is relatively fixed holder and realizes 360 ° of rotations with drawing-off threaded adjusting bar, realize adjustable drawing-off frame and adjustable drawing-off frame
On steel needle fixing clamp and Kirschner wire multi-angle regulation, make the present invention that there is multi-angle, rotatable, move up and down multidimensional adjustment
Function, this function make the shape of the present invention match with the physiology and appearance of human body limb, moulding conducive to limbs, skull, meet
The needs for the treatment of.
The bone block extension apparatus can limit the drawing-off threaded adjusting bar 9 setting in 3 fixing brackets according to treatment needs
In any one in the through-hole of position.Such as can with as shown in Figure 1, the centre being arranged in 3 fixing bracket limiting through hole that
It is a, it can also be as shown in figure 4, being arranged one on keeping to the side in 3 fixing bracket limiting through hole.
The both ends of the extension apparatus fixing bracket 1 are equipped with fixing bracket connection through-hole 2, can be led to according to treatment needs
It crosses fixing bracket connection through-hole 2 and connects steel needle fixing clamp 6 and Kirschner wire 7, can also be according to treatment needs, fixing bracket connection is logical
Steel needle fixing clamp 6 and Kirschner wire 7 are not connected on hole 2.
It is equipped with fixing bracket threaded hole 5 on the both ends end face of the extension apparatus fixing bracket 1.According to treatment needs, institute
