Description
Technical field
The present invention relates to microelectronics medical experiment manipulation instrument, is that one can be for zooperal spinal column maneuver simulated instrument, can precise quantification simulation traction, the animal spinal joint Mechanics Performance Testing device of the maneuver such as rotation, lateral bending.
Background technology
Spinal column manipulation is a kind of popular expectant treatment method mainly for strain degenerated spine soft tissue injury class disease that grew up in 20th century and rapid.Be widely used in the main expectant treatment means for the treatment of damage degenerated spine disease, because it often has the miraculous effects of getting instant result, between east and west all very popular.Spinal column maneuver: maneuver is also roughly divided into two parts generally.Part west soft tissue release maneuver is compared, and another part is that art is adjusted in joint.It is the bottleneck that maneuver research is difficult to go to the world that manipulation in existing bonesetting technology is difficult to quantize.Up to the present, the research of spinal column maneuver is mainly carried out manipulation by executing patient, and the anglec of rotation of size, direction and the strength of the each application of force of this manipulation is all difficult for repeating.So invention one can quantize rat maneuver simulation therapeutic instrument stretches in conjunction with traction, fixed point rotary, flexing, the back of the body, make the therapy apparatus of curing maneuver among tradition make to carry out in a deep going way.The mechanical simulation how can carry out specification quantification in zoopery is the bottleneck of research spinal column maneuver mechanism.
This instrument is intended the various mechanical loadings of spinal column maneuver by quantizing calibration mold, can reach the basic demand of spinal column maneuver zoopery aspect about " can repeat, can quantitatively ".This instrument is mainly used in the spinal column manual medicine experimentation of rat, from previously completely different for the extension table object of mankind's spinal disease treatment.No matter be common lumbar traction bed, still automatic control pulsed traction, three-dimensional rotation reset retractor tool on this basis that stretch spread out, it is all the clinical treatment method of inventing for basis based on conventional " traction " treatment, there is no tight associatedly with spinal column manipulation, also cannot be applied to the zoopery of spinal column maneuver.
Only traction therapeutic equipment principle just at present, its function is relatively single, only, taking the naturopathy pressing, draw as object, does not have the joint Accommodation of spinal column maneuver.As prior art CN2065907U discloses a kind of automatic compensating intermittent tractor bed, be mainly used in treating the disease such as cervical vertebra, lumbar vertebra, mainly aspect the generation of pull strength, designing.This instrument adopts pull strength and spring tension to produce trimming moment at lever two ends, after pull strength is lost, spring drives travel switch action, motor forward is compensated, add pull strength size by controlling force mechanisms control, continuously, intermittent traction and unclamping etc. by controls such as the time relay, timer, switches, under lathe bed, also have a waist massage mechanism, cervical traction is equipped amount hornwork also, and jig adopts the structure of soft continuous adjusting elasticity.Add pull strength size by controlling force mechanisms control, continuously, intermittent traction and unclamping etc. by controls such as the time relay, timer, switches.But this extension table does not possess the function of skill of imitation.
It is traction and massaging bed that prior art CN2645634Y discloses a kind of vertical clinostatism lumbar vertebra, this bed is installed on rotating frame, rotating frame can rotate around axle, rotating frame drives bed board to rotate, can realize 0--90 ° of vertical traction therapeutic at any angle, it is only 90 degree scopes that its traction and massaging angle changes, and need to manually massage, and cannot realize zooperal spinal column maneuver simulate effect.
The disclosed three dimensional tracting bed for spine of Chinese patent 95112202.9 can only simply carry out straight line traction, angulation and rotatablely move in form of therapy, and these three kinds of therapeutic modalities all do not have effectively to combine between two or between two in therapeutic process, in same direction, only draw at one time, angulation or the one of rotation in three kinds of motions, cannot realize real three-dimensional integrated treatment.Also cannot realize zooperal spinal column maneuver simulate effect.
At present, the clinical conventional lumbar traction bed function singleness that also exists, can only complete axis stretching and drawing, without the function such as part massage, rotation, all cannot realize desired spinal column maneuver simulate effect in zoopery.In order further to study the mechanical mechanism of spinal column maneuver, the invention provides a kind of accurately location on basis, simultaneously to animal draw, rotate, the spinal column maneuver analog such as swing, can be in accurate location, carry out quantitative measurement conventional spinal techniques to remove obstruction parameter under multiple various dimensions condition simultaneously, by the present invention, can test drawing, rotate, the various technical parameters of the conventional spinal maneuver such as swing, inquire into fundamental mechanism and the side effect of spinal column maneuver.
