Detailed description of the invention
for making the purpose of this utility model, technical scheme and advantage more cheer and bright, below in conjunction with detailed description of the invention and with reference to accompanying drawing, this utility model is further described.Should be appreciated that, these descriptions are exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, omitted the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
embodiment:
shown in Fig. 1-4, the controlled axial traction automatic controller of a kind of cervical vertebra of the present embodiment, comprise traction body 1, traction body 1 is driven by motor 3, and traction body 1 comprises laser locating apparatus 11, laser displacement monitoring device 12, three-axis stabilization reflecting plate 13 and controllable heads plate 14, laser locating apparatus 11 is arranged on laser positioning frame 2, two anchor points are set, one is arranged on and nose head 21 in a straight line, another is arranged on cervical region center 22, laser displacement monitoring device 12 is arranged on cervical region and hits exactly 22 sides, parallel with three-axis stabilization reflecting plate 13, three-axis stabilization reflecting plate 13 is provided with X, Y, Z 3-axis acceleration sensor, be arranged on cervical region center 22, controllable heads plate 14 is driven the top that is arranged at bed board 100 by motor, controllable heads plate 14 is provided with fixture and head is fixed, fixture can be to comprise that controllable heads plate 14 is provided with and groove and the fixing band of head dummy size.
laser locating apparatus 11 location adopts laser two point locations, initially draws secure side to location for keeping, 2 in the time of same axis, location completes.
laser displacement monitoring device 12 comprises semiconductor laser 31, signal processor 32, the first eyeglass 33, the second eyeglass 34 and linear CCD array 35.Semiconductor laser 31 Emission Lasers focus on testee 36 by the first eyeglass 33, and reflected light is collected by the second eyeglass 34, project on ccd array 35; Signal processor 32 obtains apart from the position of testee 36 by the light spot position calculating on linear CCD array 35.As the position of testee 36 changes, the light spot position on that linear CCD array 35 also can change, and the now output of signal processor 32 is the change in location of testee 36, referring to Fig. 2.
the position of the testee 36 in laser displacement monitoring is above very large on measurement result impact.For eliminating measurement error, the position, position of testee 36 is the position sensor as testee 36 with a three-axis stabilization reflecting plate 13.This three-axis stabilization reflecting plate 13 can be eliminated because of the measurement error that patient is former thereby cause.
three-axis stabilization reflecting plate 13 is arranged on patient's cervical region center 22, can automatically regulate in X, Y, Z direction.3-axis acceleration sensor is that intelligent slant angle sensor is as axle acceleration sensor, in the time that its sensing direction is consistent with acceleration of gravity direction, namely when tiltangleθ more hour, the resolution of measurement is just less, when angle enough greatly time precision just can rise.Only need draw two axle acceleration sensor measurement results, just can calculate total gradient.
3-axis acceleration sensor can obtain the value of X, Y, Z, and that sensor front end unit has adopted is stable, the capacitance sensor of low-power consumption and noise, and this front end unit comprises three acceleration sensing pieces.Due to reasons in structure, three acceleration sensing piece sensing directions and rectangular coordinate angle at 45 °, so there is a matching treatment in interface module, acceleration causes capacitance variations then in signal conditioning circuit, to be converted into change in voltage, shown in Figure 3.
signal is outputed to microprocessor 32 by 3-axis acceleration sensing, and microprocessor 32, according to X, the Y, the Z direction signal that obtain, is controlled reflecting plate 13 and done X, Y, the motion of Z direction, to keep the normal work of reflecting plate 13 and laser displacement monitoring device 12.After three-axis stabilization reflecting plate 13 puts in place, system is sent measurement commencing signal, laser displacement monitoring device 12 is started working, detect and whether have deviation to produce, produce if any deviation, this deviation signal is delivered to microprocessor 32, and microprocessor 32 drives 14 motions of controllable heads plate to make it playback to eliminate deviation according to deviation signal by controllable heads plate, then continues to implement traction.
should be understood that, above-mentioned detailed description of the invention of the present utility model is only for exemplary illustration or explain principle of the present utility model, and do not form restriction of the present utility model.Therefore any amendment of, making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model in the situation that not departing from spirit and scope of the present utility model.In addition, this utility model claims are intended to contain whole variations and the modification in the equivalents that falls into claims scope and border or this scope and border.
