Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of orthopaedics inching three-dimensional external fixed support system.
Background technology
Orthopaedics is commonly used skeleton external fixation system and is fixed affected bone, by spicule and bar linkage structure fix bone, also can comprise pressure-producing part.This external fixed support system belongs to static fixing or Manual pressurizing is fixed, and cannot determine compression levels, and be non-three dimension system, exists and uses shortcoming that is inconvenient, knochenbruch indolence.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of orthopaedics and vibrate three-dimensional external fixation system, there is three dimensional structure, fixing more reasonable firm, adopt the connecting rod with vibrating function can produce the vibration wave of favourable skeleton broken ends of fractured bone healing, have the advantages that to promote knochenbruch healing.
The three-dimensional external fixation system of orthopaedics inching, comprise the spicule being located at knochenbruch both sides, for connecting the connection tube of spicule, and for the connecting rod of affixed connection tube, spicule with connection tube, be connected by holder between connection tube with connecting rod, is characterized in that comprising a vibrating mass for generation of vibration wave in the middle part of described connecting rod.This vibrating mass is owing to producing vibration wave, and after being transferred to skeleton by spicule, energy activating cell, promotes knochenbruch healing.
Further, this vibrating mass is made up of the plectrum outside section corrugated tube of in the middle part of connecting rod and corrugated tube.This bar linkage structure is two ends is ordinary hollow pipe, and middle part is one section of corrugated tube.Because corrugated tube is hollow pipe, tube wall contains ripple, and can produce vibration wave under plectrum fluctuation, corrugated tube has good radial strength simultaneously, and what can ensure connecting rod is fixedly connected with effect.
Further, this vibrating mass is made up of the plectrum of section stiffness spring of in the middle part of connecting rod and spring outwards.So-called stiffness spring, refer to the spring had compared with large rigidity, the connecting rod that can ensure to comprise this spring can not affect it and be fixedly connected with effect because of the bending of spring.Because it has the surface of ripple struction equally, the vibration wave of similar tuning fork vibration can be produced, be passed to fracture end face by support spicule etc., good jiggle effect can be played.
Above-mentioned two kinds of bar linkage structures all have corrugated surface, can on connecting rod direction, produce fine motion and form vibration wave.
Further, described plectrum is a soft collar of socket and vibrating mass periphery.Inside this soft collar, there is some contacts, produce vibration wave by the point cantact of contact and ripple struction, there is feature easy to use.
Further, this vibrating mass is the ripple mechanism for being closely socketed in connecting rod periphery, and this mechanism comprises the ripple struction for generation of vibration wave.
Further, this ripple mechanism is the spring being closely socketed in connecting rod periphery.
Further, this ripple mechanism is the dichotomic type corrugated tube being closely socketed in connecting rod periphery.
Said structure can in the periphery being arranged on ordinary city and selling connecting rod, need not die sinking manufacture separately, have good universal performance and economy, and its ripple struction can provide good vibration wave equally.
Further, the external magnetic therapy parts of this spring, utilize the loop construction of spring to produce magnetic field.Now there are some researches prove, the magnetic field intensity of appropriate intensity is conducive to knochenbruch treatment.This programme can provide fine motion vibration wave, can provide again treatment magnetic field, kill two birds with one stone.
Feature of the present invention:
1, the blood supply of fracture end face is ensured, not injured blood vessel.
2, physiology and the mechanical environment of bone can be maintained, utilize corrugated tube elastomeric material can produce a small amount of mechanical stimulation to fracture end face, be conducive to periosteum callus formation, promote knochenbruch healing.
3, the present invention respectively implants two spicules (nail) in the two ends vertical direction of fracture, then connect separately with connection tube, connecting with the connecting rod comprising ripple struction between connection tube, in 3 D stereo pressure structure, be conducive to the pressurization of fracture end, avoid again shear direction stressometer folding stress to pressurize simultaneously, be conducive to union of fracture.
4, the invention belongs to short arm structure, compared with the mounting system of commercially available long arm structure, more can prevent the generation of the fracture redisplacement phenomenon in using.
5, existing medical research confirms, a certain amount of skeleton direction fine motion and union of fracture not contradiction, and pure tensile stress, pure compressive stress or pulsed stress are off and on conducive to union of fracture.First the present invention has rigid support system, has again the ripple struction of fine motion feature, can form of short duration compressive stress and tensile stress, and the three-dimensional fixed system of spicule makes folding stress and shear stress greatly reduce simultaneously, is therefore conducive to union of fracture.Detail such as frequency and the time of fine motion treatment of the present invention await further research.
