Be connected with 6-8 sucker with circumference array form below described base, sucker is connected with vacuum pump, base firmly can be sucked on the ground by sucker.
Described first rotating arm, the second turning arm are respectively connected with an arm bracket by two suspension strops; The both ends of described first rotating arm, the second turning arm are provided with serving motor, and the output shaft of serving motor is arranged in the horizontal direction, and the output shaft of serving motor is connected with bull wheel, and the upper end of described suspension strop is fixedly connected with bull wheel.
The bottom plate 8021 that described arm bracket includes arc and the train wheel bridge 8022 of arc be rotationally connected with bottom plate side; Described suspension strop is connected on train wheel bridge, train wheel bridge is equidistantly connected with the fixing band of more than 3, and the lower end of fixing band is removably connected with bottom plate outer wall by male and female nylon buckles; The inner bottom part two ends of described bottom plate are respectively provided with a lower pressure sensor 809, and the inner bottom part two ends of described train wheel bridge are respectively provided with a upward pressure sensor 804.
Described bottom plate two ends respectively form an articulated joint, are connected with jointed shaft between two articulated joints, and described train wheel bridge side forms the connecting hole be rotationally connected with jointed shaft.
Two long limits of described first rotating arm lower end are connected with the sensor installing plate that can slide along first rotating arm width, each sensor installing plate are provided with equidistantly 3 groups of photoelectric sensors.
Two long limits of described second turning arm lower end are connected with the sensor installing plate that can slide along the second turning arm width, each sensor installing plate are provided with equidistantly 3 groups of photoelectric sensors.
Described control panel is outward touching display screen, be provided with control circuit board in control panel, the first described motor, the second motor, the 3rd motor, the 4th motor, each photoelectric sensor, serving motor and pressure transducer are electrically connected with control circuit board respectively.Motor described in literary composition is motor.Control circuit board controls the action of each motion device by PLC or single-chip microcomputer etc., is the routine techniques means of prior art, repeats no more in literary composition.
When carrying out arthroscopic shoulder surgery, forearm being fixed on the arm bracket below the second turning arm, controlling serving motor by control panel and suspension strop is rolled up to shortest length, making offset below arm bracket and the second suspension arm and be in metastable state; Then the first motor, the second motor, the 3rd motor, the 4th motor and altitude mixture control push rod etc. are controlled by control panel, shoulder joint is made to reach the position of expection, and can timely as required shoulder joint position be adjusted according to the progress of operation, decrease assistant's labor intensity, fully appear shoulder joint gap, improve arthroscopic shoulder surgery efficiency, reduce postoperative infection risk.
When the assistive device of gesture rack as patient activity's arm, by control panel switching working mode: described serving motor controls release or roll suspension strop according to the force value of each pressure transducer, after arm is fixed on arm bracket, make arm be in relaxation state, each upward pressure sensor, lower pressure sensor obtain initial pressure value as reference value; When arm is lifted, upward pressure sensor detects that force value increases, and the serving Electric Machine Control suspension strop of relevant position is rolled; When arm moves down, lower pressure sensor detects that force value increases, and the serving Electric Machine Control suspension strop of relevant position is released.
When more than one suspension strop is released completely, altitude mixture control push rod shortens, and records to lower pressure sensor the maximum that pressure reaches setting; When more than one suspension strop is rolled completely, altitude mixture control push rod extends, and supreme pressure transducer records the maximum that pressure reaches setting.
When the suspension strop near the 3rd motor side on first rotating arm is released completely, and when the suspension strop of opposite side is rolled completely, then the second motor drives first rotating arm upwards to rotate; Otherwise when the suspension strop near the 4th motor side on first rotating arm is released completely, and when the suspension strop of opposite side is rolled completely, then the second motor drives first rotating arm to rotate.
When photoelectric sensor on described first rotating arm on a limit detects and is blocked, then the 3rd motor rotates to the photoelectric sensor side be blocked; When photoelectric sensor on described second turning arm on a limit detects and is blocked, then the 4th motor rotates to the photoelectric sensor side be blocked.Like this, gesture rack is servo-actuated in real time according to the active state of patient's arm, reduces exerting oneself of patient's arm muscles, has both played exercise effect, and avoided again energy to spend and cause greatly wound pain even secondary damage.
By the position of adjustment sensor installing plate, can the position of corresponding adjustment photoelectric sensor, when the position of photoelectric sensor is more outer, then arm needs mobilely just can trigger photoelectric sensor by a relatively large margin; Contrary, when the position of photoelectric sensor is more inner, then arm moves and more just can trigger photoelectric sensor.Namely by the sensitivity of the position of adjustment sensor installing plate and adjustable the 3rd motor, the 4th electric machine rotation.
In addition, on described first rotating arm, one group of photoelectric sensor of the same side can set different spans of control limit of control, that is: when the photoelectric sensor of the second turning arm detects signal, illustrate that large arm rotation amplitude is less, 3rd motor rotation speed is less, when the relative photoelectric sensor the closer to the 3rd motor side detects signal, then the 3rd motor rotation speed increases relatively.
In like manner, on described second turning arm, one group of photoelectric sensor of the same side can set different spans of control limit of control, that is: when the photoelectric sensor of the second turning arm outer end detects signal, illustrate that forearm rotation amplitude is less, 4th motor rotation speed is less, when the relative photoelectric sensor the closer to the 4th motor side detects signal, then the 4th motor rotation speed increases relatively.
