The treating instrument for injured bone is composed of a power supply input device, a frequency generator and regulator, a power adjusting device, a power amplifiers, a treatment coil, a frequency display device, and a magnetic density display device. The treatment frequency range of the treating instrument for injured is arranged between 0.75-19 hertz, which can continuously adjust; the magnetic density is arranged between 0-250 gauss, which can continuously adjust. The treating instrument for injured treats the fresh fracture 36 cases such as the tibiofibula, the shaft of humerus, the ankle joint, the calcaneus, the patella, and distal end fracture of radius, and the average healing time is about 18.8 days, the utility model provides a shortcut for the patient of the bone fracture.
Description
This utility model is a kind of medical apparatus and instruments with bone injurys such as pulse electromagnetic field stimulation therapy fracture.
This century middle fifties, Japanese scholar pacifies the field and finds: impose little electricity at bone stump and can induce the regeneration of bone to form.After this, many in the world countries have all carried out the research of electricity irritation to bone and regenerating bone or cartilage effect, and begin to be applied to clinical in the seventies, and in 1 or the nine years July 1st, Fridenberg has cured the patient of a routine internal malleolus disunion first with the method for galvanic stimulation.China does not begin electricity irritation skeletonization theory is studied in the seventies yet, and has obtained clinical experience.
Electricity irritation skeletonization method roughly is divided into two classes: intrusion method and non-intruding method.The intrusion method is that electrode is inserted in the bone, and the pulse direct current that passes to 5～20 microamperes stimulates bone stump, makes its regeneration.This method is that electrode is directly inserted in the bone through skin, infects probably.The non-intruding method is to cause a pulse current with magnetic field or electromagnetic field at bone stump, and to reach the effect of impelling bone growth, it has avoided inserting the infection that may cause because of electrode.But the therapeutic equipment volume is big, and treatment time long (need treat more than 12 hours every day).At present, electronic stimulation is used for delayed healing fracture and bone does not connect more.
The purpose of this utility model be manufacture and design a kind of portable, be mainly used in fresh bone injury carried out electronic stimulation, and treatment time short non-intrusion type bone healing machine.
Therapy apparatus described in the utility model is made up of power supply input equipment, frequency generation and adjusting device, apparatus for adjusting power supply, power amplifier, treatment coil and frequency demonstration, magnetic field intensity display device.
Fig. 1 is this utility model operation principle block diagram.
Fig. 2 is this utility model circuit theory diagrams.
Operation principle of the present utility model as shown in Figure 1. Among the figure:
1 power supply input unit;
2 frequencies take place and adjusting device;
3 apparatus for adjusting power supply;
4 power amplifiers;
5 treatment coils;
6 frequencies show;
7 magnetic field intensities show.
After power supply input equipment (1) is carried out processing such as blood pressure lowering, rectification, filtering with the alternating current that receives, supply with frequency with the unidirectional current form and take place and adjusting device (2) and apparatus for adjusting power supply (3), they control frequency range and the magnetic field intensity of adjusting actual needs respectively; Signal by (2) and (3) output is received by power amplifier (4), finally delivers to treatment coil (5) after signal amplifies.For ease of adjusting the frequency and the magnetic field intensity of treatment, also be provided with frequency and show that (6) and magnetic field intensity show (7).According to comparison of mould rope and test repeatedly, the therapeutic frequency scope of this bone healing machine is arranged between 0.75 hertz～19 hertz, and magnetic field intensity is arranged between 0～250 Gauss, and all is continuously adjustable.
Embodiment: the physical circuit of realization this utility model design as shown in Figure 2.

(5) diameter chosen of treatment coil L is bigger, as 20cm, according to Hull theorem now suddenly, is balanced fixed at this apart from internal magnetic field, and fills in coil with iron core, to increase magnetic flux, connect with the nonmagnetic substance bar between two coils, its central point is maintained fixed, and adjusting handle is housed, distance therebetween can be adjusted in 7～20cm scope flexibly.
The low frequency treating instrument for injured bone of making according to the utility model design, all continuously adjustable because of its several main treatment parameters (such as magnetic field intensity, frequency etc.), can be easily impose treatment for the depth of different wound site, wound etc.; Especially the utility model arrange with the diverse frequency range of existing treating instrument for injured bone, alleviated largely because of the too high misery of bringing to patient with bone fracture of frequency of stimulation, and treatment time shortens dramatically, and treats continuously every day 4 hours, just can receive obvious curative effect. Because coil diameter is big, the maximum therapy area can reach 400cm2, and interior cored, the degree of heat of coil is alleviated greatly. With this machine four limbs fresh fracture patient is carried out clinical treatment, all obtain preferably effect, according to statistics, can shorten healing time 1/4～1/3, reduced patient's bed, the hospital stays. According to clinical observation, with these machine treatment fracture of tibia and fibula 18 examples, average healing time is 22.5 days, fracture of shaft of humerus 4 examples, average healing time 18 days, fracture of ankle joint 5 examples, average healing time 21.4 days, fracture of calcaneus 3 examples, average healing time 14 days, patellar fracture 3 examples, average healing time 21 days, distal radius 3 examples of fracturing, average healing time 16 days, when treatment, have obvious detumescence, pain relieving effect. This machine also can be used for the auxiliary curing of bone delay in healing, bone nonunion, soft tissue injury, limbs fixation syndrome except can treating the four limbs fresh fracture, and be used for the ligament reparation, Nerve regneration etc. Treating instrument for injured bone described in the utility model provides shortcut for the early rehabilitation of fracture patient.
