Abstract
The utility model relates to an intelligence type recovery therapeutic instrument for limb passive exercise, which is designed for a limb malfunction patient resulted in trauma, osteoarthropathy or nervous system pathologic change clinically. The patient has persistent passive movement under the control of a computer to reach the purpose of recovery. The instrument is composed of a mechanical part, an electric circuit part and a computer part. Primary, a metal case is arranged on a metal support of the mechanical part, a step motor is arranged in the metal case, and the step motor drives a turntable and a driving system to move through a bearing and a gear of the step motor. The step motor is provided with two pressure sensors which are connected with an A/D conversion plate, an electric motor control circuit, etc. through output wires of the sensors and a control wire of the electric motor, and the A/D conversion plate, the electric motor control circuit, etc. are arranged in the computer. The instrument is scientific and practical after clinical tryout.
Description
This utility model belongs to medical apparatus, has realized that under microcomputer control, (ContinuousPassive Motion CPM), has reached the passive therapy rehabilitation purpose of intelligent multifunctional limbs to continue passive activity.
Some disease of clinical orthopaedics, wound can cause osteoarthrosis dysfunction, articular cartilage degeneration.Bone surgery also can cause joint accretion, contracture.As extremity fracture especially intra-articular fracture, after the arthropathy operation, the articular cartilage defect prothesis, the suppurative arthritis drainage is after the operation of tendon injury prothesis.In addition, amyotrophy etc. after cerebrovascular disease, neuropathy and the damage.Above-mentioned sick the damage not only brought misery to patient, also is the burden of family and society, therefore, strengthens such patient, and impel and suffer from limb restore funcitons as early as possible, be one of important topic anxious to be solved in this area.The method that is adopted (1) AFL's passive activity was wasted time and energy in the past; (2) begin to use various types of joints passive exercising apparatus the seventies abroad, domestic have a lower limb passive exercising apparatus the eighties, the mid-90 has been developed the elbow joint passive exercising apparatus, though it is effective in cure, but be the simple mechanical structure, can not objective and quantified controlling joint motion amplitude, treatment time and comprehensive function training.
At the problems referred to above, this utility model purpose is that design is a kind of under microcomputer control, can carry out orientation, spacing (amount), periodic passive exercise according to different parts (limbs joint), physiological function and bearing strength, have limbs instrument for treating and recovering easy to use, that science is practical.
The design is in clinical position experience for many years with on to human dissection, physiological function and continuous passive motion research basis, through repetition test, is achieved.Its primary structure and function are as follows:
This instrument comprises mechanical part, circuit part and microcomputer three parts, as shown in Figure 1.
Mechanical part mainly is made up of gear train, bearing, rotating disk, motor and drive rod etc.Its structure was made up of base 1, connecting rod 2, jack back 3, cabinet 4, rotating disk 5, drive link 6, bearing 7 etc. as (Fig. 1,2 shows).Base 1 is a heavy metal base, is the vertical metal that connects and composes with the connecting rod 2 that seamless steel pipe is welded into; The jack back 3 of control cabinet lifting (being support height) is housed on the connecting rod, and connecting rod top and cabinet 4 join.Cabinet 4 is the length 25～35cm that is welded into metallic plate, the casing of wide 20～30cm, high 25-35cm, in be provided with motor, pressure transducer, bearing etc.; Cabinet one side connects rotating disk 5A by bearing 7, and the bearing of opposite side connects rotating disk 5B; Rotating disk 5A is provided with the scale souvenir, and rotating disk 5B is connected with drive rod 6; Drive rod is provided with the gimbal lever 10.Step motor control line 8 and the pick off output lead 9 that is connected with microcomputer arranged at the cabinet bottom.
Cabinet inner structure (as shown in Figure 3) comprises bearing 7, motor 11 and 2 pressure transducers 12 etc.Motor is inductor type motor (prior art), is positioned at the bottom of cabinet, link to each other with 2 pressure transducers by bearing, gear, and external 2 ring flanges of pressure transducer, the adnexa that is mainly used in the gimbal lever and joint motion is installed.The motor that is positioned at the cabinet bottom is drawn 4 leads, forms step motor control line 8, connects motor control module.Motor control module mainly is the normal operation of control motor, and supply voltage is ± 5V.2 external 8 leads of pressure transducer are formed pick off output lead 9, are connected with microcomputer, control the output of pick off by the torgue measurement circuit board of microcomputer inside, further control the balance of rotating disk (ring flange); Simultaneously the signal of pick off again by the torgue measurement circuit board after over commutation, filtering and signal amplify, obtain analogue signal, give microcomputer through the A/D change-over panel with the situation of change of signal again, so that realize control in real time.2 outer rotating disks of cabinet link to each other with bearing by gear, and purpose is in order to reach equalising torque, and it is positioned at the cabinet top.Phase case and base and connecting rod are connected as a single entity, and control the height of cabinet by the jack back on the connecting rod, use so that be fit to the people of differing heights.
Computer part (being prior art), can adopt main frame is PCl * T-386 type, is furnished with printer.Adorn a special A/D change-over panel in the microcomputer, torgue measurement circuit board and motor control module.The A/D change-over panel is the bridge between torgue measurement analog circuit and motor control module and the computer, and in design, we are circuit part and computer case altogether, unified use a computer provide ± the 12V power supply, avoid the error that causes because of power supply is inconsistent.Motor control module is used for translating the information that A/D provides, the rotating of control motor (promptly anxious stopping and startup).Drive stepping motor is normally moved.
Circuit part (as Fig. 4, shown in Figure 5) comprises torgue measurement circuit, A/D conversion and motor control module.Torgue measurement circuit (see figure 5) adopts the identical resistance strain type sensor of 2 covers, and is equipped with the identical treatment circuit of 2 covers, can classify effectively and train, and the moment can be to training the time monitors, and there are higher sensitivity and accuracy in the system of assurance.
Power source of the present utility model mainly is the moment that is used for transmitting step motor shaft output, the periodicity of finishing by the computer defined moves back and forth, and drive and to drive bar and make limbs do corresponding various training, as stretching in the wrong, interior receipts abduction and rotatablely move in the joint, during training, the limbs joint angle can set in advance by computer according to patient's actual needs, and can read from graduated disc.Adopt motor as power source, its excellent being can accurately be controlled rotating speed of motor and corner by computer to the umber of pulse that motor sent.In order to increase the output torque of motor, also take deceleration transmission (speed ratio 37/1) and the gimbal lever is housed, make the power output of this instrument reach 5 ± kilogram, realized the automatization of treatment and training, realized original design purpose fully through clinic trial.
