Required biomechanical environment is provided for union, is able to satisfy patient's functional rehabilitation need of exercise, is a kind of good orthopaedics
Operative treatment technology.This method is neither interior fixation, nor outer fixed, but fixed in playing over cannot reach with outer fixation
The effect arrived.
Existing exterior fixing rack generally includes spicule and Ring splint, and spicule is mounted on annular by universal hold-doun nut
On brace, but existing Ring splint is usually fixed diameter, can not be adjusted according to limbs of patient size, usually to trouble after wearing
Person's life, action cause larger inconvenience.
Summary of the invention
The present invention is intended to provide scalable bone defect healing external fixer, can according to limbs of patient size adjusting size,
To need the bone defect patient of limb reconstruction to provide more comfortable treatment experience.
In order to achieve the above objectives, The technical solution adopted by the invention is as follows:
A kind of scalable bone defect healing external fixer, including 4 scalable Ring splints and universal spicule device, 4
A scalable Ring splint is integral by the connection of multiple connecting rods, above and below 4 scalable Ring splints, is spaced setting；Each
There are at least two universal spicule devices on scalable Ring splint.
Further, scalable Ring splint includes the first semi-ring and the second semi-ring, the end of the first semi-ring and the second semi-ring
Portion struts arm connection by sliding.
Further, sliding struts the sliding bar that arm includes straight-arm He can lock, and the straight-arm is equipped with sliding slot, the cunning
Lever is in sliding slot, and the both ends of the first semi-ring are respectively and fixedly connected with a straight-arm, and the second semi-ring both ends are respectively and fixedly connected with a sliding bar.
Wherein, sliding bar is locked by locking nut.
Further, connecting rod is threaded rod, there is the through-hole being adapted to connecting rod on scalable Ring splint, and connecting rod is logical
Locking nut is crossed to be locked with scalable Ring splint.
Preferably, connecting rod has four.
Wherein, universal spicule device includes fixed pin and universal hold-doun nut, and the universal hold-doun nut is mounted on and can stretch
On contracting Ring splint, fixed pin is on universal hold-doun nut.
Preferably, the diameter of fixed pin is 2mm.
Compared with prior art, the invention has the following advantages:
The present invention can be according to the size of the scalable Ring splint of the big minor adjustment of limbs of patient, and 2mm steel needle is more minimally invasive, part
Blood fortune interference is small, can experience to need the bone defect patient of limb reconstruction to provide more comfortable treatment, and more more options；Through more
Plane puncture needle, fixed reliable, stress distribution is uniform, and limbs angulation deformity can be corrected while repairing bone nonunion.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of scalable Ring splint；
In figure: the first semi-ring of 1-, the second semi-ring of 2-, the universal hold-doun nut of 3-, 4- locking nut, 5- through-hole, 6- connecting rod,
7- fixed pin, 8- fixed link, 11- straight-arm, 12- sliding slot, 21- sliding bar.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
As shown in Figure 1, 2, scalable bone defect healing external fixer disclosed by the invention, including 4 scalable annulars
Brace and universal spicule device, 4 scalable Ring splints are connected integral by multiple connecting rods 6, it is preferable that connecting rod 6
There are four, the spacing distance of adjacent two connecting rods 6 is suitable.Above and below 4 scalable Ring splints, it is spaced setting, two of them
Scalable Ring splint is distal loop, and another two is proximal loop.There are at least two universal spicules on each scalable Ring splint
Device.Wherein, universal spicule device includes fixed pin 7 and universal hold-doun nut 3, and universal hold-doun nut 3 is mounted on scalable ring
On shape brace, fixed pin 7 is on universal hold-doun nut 3, and every fixed pin 7 is with there are two universal hold-doun nut 3, fixed pins 7
Head and the tail both ends it is fixed by a universal hold-doun nut 3 respectively, the mechanics for obtaining respective planes is stablized.Universal hold-doun nut 3 is
Common steel needle fixing clamp in existing Orthopaedic external fixator, details are not described herein again for structure.
Scalable Ring splint includes the first semi-ring 1 and the second semi-ring 2, and the end of the first semi-ring 1 and the second semi-ring 2 passes through
