Abstract
The invention relates to the technical field of medical apparatuses, in particular to an orthopedic micromotional three-dimensional external fixing bracket system. The orthopedic micromotional three-dimensional external fixing bracket system comprises bone needles arranged on the two sides of a fractured bone, connecting pipes for connecting the bone needles, and a connecting rod for fixedly connecting the connecting pipes, wherein the bone needles and the connecting pipes, and the connecting pipes and the connecting rod are connected through fixers; the orthopedic micromotional three-dimensional external fixing bracket system is characterized in that a vibrating component for generating a vibration wave is arranged at the middle part of the connecting rod; the vibrating component can generate the vibration wave, so that after the vibration wave is transmitted to the bone through the bone needles, cells can be activated and the healing of the fractured bone can be promoted; and the orthopedic micromotional three-dimensional external fixing bracket system adopts a three-dimensional structure, is more reasonable and firmer in fixation, can generate the vibration wave benefiting the healing of fractured ends of the bone through the connecting rod with a vibrating function, and has a characteristic of promoting the healing of the fractured bone.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to the three-dimensional exterior fixation bracket of a kind of orthopaedics fine motion formula system.
Background technology
Orthopaedics skeleton external fixation system commonly used is affected bone fixedly, through spicule and bar linkage structure fix bone, also can comprise pressure-producing part.This exterior fixation bracket system belongs to stationary or manual work adds press fit, can't confirm the pressurization degree, and be non-three dimension system, has the shortcoming of using inconvenience, knochenbruch indolence.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned prior art; Provide a kind of orthopaedics to vibrate three-dimensional external fixation system, had three dimensional structure, fixing more reasonable firm; The connecting rod that employing has vibrating function can produce the vibration wave of favourable skeleton broken ends of fractured bone healing, has the advantages that to promote the knochenbruch healing.
The three-dimensional external fixation system of orthopaedics fine motion formula; Comprise the spicule of being located at the knochenbruch both sides; Be used to connect the connection tube of spicule; And the connecting rod that is used for affixed connection tube, be connected through holder between spicule and connection tube, connection tube and the connecting rod, it is characterized in that said connecting rod middle part comprises a vibrating mass that is used to produce vibration wave.This vibrating mass be owing to can produce vibration wave, be transferred to skeleton through spicule after, can activating cell, promote the knochenbruch healing.
Further, this vibrating mass is made up of the one section corrugated tube at connecting rod middle part and the plectrum in the corrugated tube outside.This bar linkage structure is that two ends are common hollow pipe, and the middle part is one section corrugated tube.Because corrugated tube is a hollow pipe, tube wall contains ripple, under the plectrum fluctuation, can produce vibration wave, and corrugated tube has good radial strength simultaneously, can guarantee the fixed connection effect of connecting rod.
Further, this vibrating mass is made up of the one section stiffness spring at connecting rod middle part and the plectrum in the spring outside.So-called stiffness spring refers to the spring with big rigidity, can guarantee that the connecting rod that comprises this spring can not influence its fixed connection effect because of the bending of spring.Because it has the surface of ripple struction equally, can produce the vibration wave of similar tuning fork vibration, be passed to the fracture end face through support spicule etc., can play good jiggle effect.
Above-mentioned two kinds of bar linkage structures all have corrugated surface, can both on the connecting rod direction, produce fine motion and form vibration wave.
Further, said plectrum is a soft collar of socket and vibrating mass periphery.This soft collar inboard has some contacts, contacts with the point of ripple struction through the contact and produces vibration wave, has characteristics easy to use.
Further, this vibrating mass is the ripple mechanism that is used for closely being socketed in the connecting rod periphery, and this mechanism comprises the ripple struction that is used to produce vibration wave.
Further, this ripple mechanism is for closely being socketed in the spring of connecting rod periphery.
Further, this ripple mechanism is for closely being socketed in the dichotomic type corrugated tube of connecting rod periphery.
Said structure can be in the periphery that is arranged on the empty connecting rod of ordinary city mid-sales, and die sinking manufacturing 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.Existing research proof, the magnetic field intensity of an amount of intensity helps the knochenbruch treatment.This programme can provide the fine motion vibration wave, and treatment magnetic field can be provided again, kills two birds with one stone.
Characteristics of the present invention:
1, guarantees the blood supply of fracture end face, not injured blood vessel.
2, can keep the physiology and the mechanical environment of bone, utilize the corrugated tube elastomeric material to produce a small amount of mechanical stimulation, help the periosteum callus formation, promote the knochenbruch healing the fracture end face.
3, the present invention respectively implants two spicules (nail) in the two ends vertical direction of fracture; Connect separately with connection tube then; Connecting, be 3 D stereo pressure structure between connection tube, help the pressurization of fracture end with the connecting rod that comprises ripple struction; Avoid simultaneously the pressurization of shear direction stressometer folding stress again, help union of fracture.
4, the invention belongs to short arm structure, compare, the generation of the fracture redisplacement phenomenon in more preventing to use with the mounting system of commercially available long arm structure.
5, existing medical research confirms that fine motion of a certain amount of skeleton direction and union of fracture be contradiction not, and pure tensile stress, pure compressive stress or pulsed stress off and on help union of fracture.The present invention at first has the rigid support system, has the ripple struction of fine motion characteristic again, can form of short duration compressive stress and tensile stress, and the three-dimensional fixation system of spicule reduces folding stress and shear stress greatly simultaneously, therefore helps union of fracture.The detail of fine motion treatment of the present invention such as frequency and time await further research.
