Detailed description of the invention
This utility model is further illustrated below in conjunction with embodiment and accompanying drawing thereof.
The Taylor Jia Gu rehabilitation institution (being called for short rehabilitation institution, see Fig. 1-4) of this utility model design: its composition comprises breast piece and power section.Wherein, breast piece comprises distal loop 1, Kirschner wire 2, hinge 3, extension rod 4, subring 5, proximal loop 6, connecting bolt 7, rotary compression spring 8, nut 9, its annexation is: distal loop 1 is connected and fixed with proximal loop 6 Kirschner wire 2, connecting bolt 7 compresses rotary compression spring 8 and is connected with proximal loop 6, subring 5 and distal loop 1 are original two rings of existing Taylor's frame, and rotary compression spring 8 and connecting bolt 7 are connected to proximal loop 6 on subring 5.Power set include block rubber 11, piezoelectric ceramics 10.Its annexation is: block rubber 11 is fixed in subring 5 upper surface, and piezoelectric ceramics 10 is fixed on block rubber 11, and the top of piezoelectric ceramics 10 is connected with proximal loop 6 lower surface.
This utility model rehabilitation institution is at fracture calibration phase: proximal loop 6 and subring 5 use connecting bolt 7 to fix, and the installation operation between skeleton with ring is identical with existing Taylor's frame.With the fixing fracture of Kirschner wire 2 and anatomical position, two Kirschner wires 2 are holed perpendicular to the phalanges longitudinal axis in astragalus broken line 0.5 centimeters of fracture near-end and far-end respectively, through bilateral cortical bone, these two pieces of Kirschner wires 2 should in a plane, and this plane should with phalanges longitudinal axis.Take out this two pieces of Kirschner wires 2, insert injection needle as conduit, passed by steel wire, then tighten, pressurize, be equivalent to tension band wire at needle track place, such is fixing very firm.Six telescopic extension rods 4 are connected subring 5 and distal loop 1 obliquely, can rotate freely at junction point place, as long as regulate the length of a wherein extension rod 4, proximal loop 6 and subring 5 entirety will change position by opposite proximal end ring 1.And the length of six telescopic extension rods 4 uses computer software to calculate according to patient profiles.This device is treated and is corrected various simple or complicated fracture and deformity.In the fracture recovering stage: connecting bolt 7 unclamps, spiral compression spring 8 recovers former length and three rotary compression springs are 120 ° between any two.Different piezoelectric ceramics 10 can vibrate when powering on.Piezoelectric ceramics 10 shuttle belt dynamic auxiliary ring 4 and distal loop 1 vibrate, and the power of vibration is determined by the thickness of five piezoelectric ceramics 10 and power-on voltage.Piezoelectric ceramics 10 vibration causes spring generation deformation, produces slight distance consecutive variations, so circulate between proximal loop 6 and subring 5, produces vibration.The vibration of the spacing change generation of proximal loop 6 and subring 5 causes the vibration between skeleton, thus promotes the better rehabilitation of skeleton, shortens knochenbruch rehabilitation duration.
In existing Taylor Jia Gu rehabilitation institution, Taylor's frame of dicyclo rigid structure only possesses and corrects and the function of fixation of bone fragments, though Taylor's frame of tricyclic structure can realize the growth vibratory stimulation of convalescence to knochenbruch, practical operation trouble, safety and effectiveness limited.
The whole support body of this utility model is still designed to tricyclic structure, is proximal loop 6, subring 5 and distal loop 1 respectively.But piezoelectric ceramic piece 10 is arranged between proximal loop 6 and subring 5 as vibrating elements, such proximal loop 6 is linked together by piezo-ceramic vibrators with subring 5; Determine the material of piezoelectric ceramic piece and thickness and its power-on voltage, the just vibrational state of controlled piezo ceramic element processed, piezoelectric ceramic piece 10 is energized, and just can produce vibration, and this transfer of vibration, to proximal loop 6, just can be vibrated.Under the effect of rotary compression spring 8, subring 5 also can vibrate with proximal loop 6, this vibrational energy more stably acts between two pieces of knochenbruch, knochenbruch place is made to obtain the vibratory stimulation of the low amplitude value of certain frequency, shorten fracture recovering process, promote that osteocyte increases, thus shorten fracture recovering process.
At fracture calibration phase: proximal loop 6 and subring 5 are fixed as one, and form known two ring Taylor framves, realize the reset of skeleton with distal loop 1 and six roots of sensation extension rod 4.
In the fracture recovering stage: proximal loop 6 and subring 5 are separated into soft strength, subring 5 and distal loop 1 are fixed as one by six roots of sensation extension rod 4, and subring 5 vibrates with the vibration of piezo ceramic element, and this slight vibration stimulates, and can assist the rehabilitation of knochenbruch.
Innovative point of the present utility model replaces motor as power resources with piezoceramic material, and frame bone parts and drive part are combined, and the two forms an entirety, and whole like this frame bone mechanism is easier, easily operates; In addition, designed piezoelectric ceramics chip architecture can realize various dimensions vibration, more targetedly, can act on more neatly between bicyclo-knochenbruch, make it obtain the vibratory stimulation of low amplitude value, shortens bone validity folding recovering process, promotes that osteocyte increases.By contrast, this utility model Taylor frame has greater flexibility and stronger practicality.
