Description

Multi-functional medical instrument for bone treatment

This utility model is the innovation and creation about the multifunction vibration bone treatment, belongs to the electrical category medical apparatus and instruments.

Scientists after deliberation, proposed compressive stress to the fracture healing be a key factor, can stimulate the theory of the growth of area of new bone.Chinese American Feng Yuanzhen professor once pointed out in " biomechanics " book: we can control reproducing of bone by mechanical stress, and this stress can be by doing gymnastics or assistive device applies, to promote patients ' recovery.

This utility model task is based on above-mentioned principle, and a kind of multifunction vibration bone treatment that can produce tension and compression stress to patient's fracture site is provided, and with this bone treatment fracture patient is treated, and reaches the purpose that promotes patients ' recovery.

Task of the present utility model is finished as follows.The multifunction vibration bone treatment has the pulse power part (IV) of an adjustable pulse frequency, power and removable, lifting, fixed instrument support partly (II), it is characterized in that also having an electric-controlled mechanical vibration machine (I) part and connects, mechanical vibration are imported patient part and according to the hitch of the different various different structure shapes that design of patient's fracture site partly (III) with the vibrating arm axle (1) of mechanical vibrator generator (I).

Electric-controlled mechanical vibration machine (I) is by being fixed on the electric magnet ferrum stamen (10) on framework end cap (4) (13) and the framework tube (12) and containing the magnet exciting coil (11) that the ferrum stamen is provided with, armature (8) and joining with it vibrating arm axle (1), two ends of vibrating arm axle (1) are equipped with spring (6) and spring base (5) and gland (15) (3) and wait other to constitute by parts.

The hitch of various different structure shapes (III) can be that tibia supporting plate hitch (27) humerus supporting plate hitch (28), chi are scratched bone supporting plate hitch, neck of femur supporting plate hitch (29) and femoral shaft vibration bow hitch (30) etc.

The operation principle of multifunction vibration bone treatment is, the adjustable pulse frequency that can be finished by general circuit, the pulse power of power provide the electric impulse signal of certain frequency, certain power to the magnet exciting coil of the containing electric magnet ferrum stamen setting of electric-controlled mechanical vibration machine, magnet exciting coil is done the time spent at suitable pulsed power signal, electric magnet ferrum stamen produces magnetic force, overcome spring force, adhesive armature, do the time spent and work as the magnet exciting coil pulse-free signal, promptly do the time spent at two interpulse electronegative potentials, the electric magnet ferrum stamen magnetic that breaks, by the active force of spring with the armature pop into position.When magnet exciting coil is done the time spent at the consecutive pulses signal, the corresponding generation pulsed of electric magnet ferrum stamen magnetic force then, armature and the relative electric magnet ferrum of the vibrating arm axle stamen that is connected as a single entity with it produce mechanical vibration.When fracture patient being treated with this instrument, can be according to the different situations of fracture site, select suitable hitch, pass through hitch, on the vertical direction of fracture face, the mechanical vibration that the electric-controlled mechanical vibration machine is produced reach patient's fracture, because the importing of mechanical vibration makes patient's fracture site produce corresponding tension or compressive stress, promote the growth of fracture site area of new bone.

In electric-controlled mechanical vibration machine of the present utility model (I), two springs (6) that two ends of vibrating arm axle (1) are set promptly are necessity parts in addition that vibration takes place, and also are that patient's fracture site is applied prestressed part in addition.To patient's fracture site on vertical fracture face direction; oriented apply prestressing force again vibration therapy be an important feature of the present utility model; this prestressed size; can determine by the adjustment of pressure-indication means monitor mode is set in instrument; prestressing force size and vibration therapy time length, stressing conditions and deciding during normal activity before general modal patient fractures.This prestressed applying to preventing to roll over the dislocation of bone, and to the healing of fracture, has great role.

In electric-controlled mechanical vibration machine of the present utility model, because armature (8) is fixed between the two ends of bar axle (1), so when work, it is opposite to conduct to the direction of the stress that fracture site produces at vibrating arm axle (1) two ends by hitch (III), can be according to fracture site different and the treatment needs are selected or drawing-type vibration or apply two kinds of therapeutic modalities of compressive stress formula vibration.When patient's fracture site obviously misplaces and local swelling when remarkable, can carry out the drawing-type vibration, help rolling over reduction and swelling and eliminate.After treating the reduction of the fracture, can carry out the vibration of compressive stress formula, promote the fracture symphysis.

The instrument support of multifunction vibration bone treatment of the present utility model, the guiding mechanism with removable, lifting, function such as fixing adapts to the different situation of the various postures of patient in the patient at miscellaneous fracture position and the treatment.

This utility model is based on the principle of reproducing of utilizing mechanical stress control bone, the multifunction vibration bone treatment of design, the treatment bone fracture bone fracture disease of utilization, broken the fracture after must rest, immobile conventional idea, for biomechanics has increased new content, opened up effectively new approach of treatment bone fracture bone fracture disease.It has the following advantages, and can promote the rehabilitation of fracture patient, has shortened treatment cycle, and the present inventor is from utilizing the fracture of tibia patient case (inner on probation) of this vibration bone treatment for difficult healing, and average energy is one month earlier fully recovered.Also have widely used advantage, extremity tubulose long bone fracture all can be used, and particularly is difficult for the treatment of the fracture of femoral neck of treatment for conventional method, has proposed the theoretical and very medicable treatment means of new treatment.Also can treat soft tissue injury and general traumatic injury with this instrument, the affected part can be played through vibration and be eliminated the effect of swelling and ache, and has the effect of relaxing muscles and tendons to promote blood circulation.It is to be not damaged treatment to fracture patient that this utility model also has an outstanding feature, and the patient is ready to receive treatment, and the inner clinic trial in the court proves that the patient can fall asleep, and also can treat in sleep in treatment.The vibration bone treatment also has simple and reasonablely, and cost is low, and is easy to use, and the patient such as also can manipulate at advantage.
