The specific embodiment
First kind of embodiment: as shown in Figure 1, 2, 3, this general positioning chair for cephalometry is made of seat 1 and cephalometer 2, and seat 1 is made of chair lower limb 3, seat 4 and backrest 5, and cephalometer 2 is installed in the top of backrest 5.
By Fig. 4,5 visible a kind of adjustable for height backrests 5, backrest 5 bottoms are one section sleeve pipes 6, and the inside of sleeve pipe 6 is inserted with one section expansion link 7 that can slide up and down, and expansion link 7 is gone up available navigation button 8 in position and fixed.By adjusting the height of backrest 5, can change the height of cephalometer, to adapt to different receptors' needs.
Fig. 6,7 has introduced a kind of fixed cephalometer 2 of head that is suitable for, cephalometer 2 has a box-like console panel 10, many locating detents 9 are housed below the console panel 10, console panel 10 the insides are provided with the thrust mechanism of control locating detent 9 plan-positions, and the joystick 11 of thrust mechanism is housed above the console panel 10.As seen, locating detent 9 is to constitute by two sections among the figure, and epimere is to be connected in console panel 10 following pawls to overlap 12, and pawl has put slotted hole 13, and hypomere is to overlap the claw 15 that slides up and down in 12 at pawl, and fixing button 14 is arranged at claw 15 tops.Here pawl cover 12, fixing button 14 and claw 15 all will adopt the good material of X line permeability to make, and the claw end is provided with the labelling metal dots.
Fig. 8 has introduced a kind of thrust mechanism of adjusting locating detent 9 plan-positions.Thrust mechanism has one to be contained in console panel 10 intermediary rotating shafts 16, a fork 17 is connected below the rotating shaft 16, the fork 17 two ends one section pull bar 18 that is hinged respectively, the upper end of pull bar 18 other end hinge locating detents 9, the upper end of locating detent 9 are assemblied in 19 li of the chutes of console panel 10.Pull handle 11, rotating shaft 16 is rotated, and drives fork 17 swings, can spur locating detents 9 in 19 li slips of chute by pull bar 18, thereby changes the plan-position of locating detent 9.
Fig. 9,10 has represented the duty of this cephalometer, as shown in the figure, people's head is placed within three claws 15, adjusts the length of claw 15 again, makes its end points relative with the feature locations of head.In general, the claw 15 most advanced and sophisticated nominators' of both sides ear nest, positive claw 15 nominators' the nasion, fixing by fixing button 14 again, can reach the localized purpose of head.
Exemplified the mated condition of this positioning chair and a kind of DR camera 20 as Figure 11.DR positioning radiography machine 20 among the figure has the slideway 23 of a setting, crossbeam 22 of assembling on the slideway 23, and 22 1 on crossbeam is equipped with X line emitter 21 and manipulation device, and receptor 24 is equipped with in the other end.During work, this positioning chair is placed between the accepter 24 and emitter 21 of DR camera earlier, and near accepter 24 1 sides, the video that forms on accepter by the light and the localizer of camera emitter is adjusted the position of seat 1, make localizer locating detent 9 be in correct position, ask the receptor to sit on the seat 4 again, suitably adjust the height of backrest 5, make three claws 15 of the locating detent 9 of localizer 2 replace the ad-hoc location of receptor's head respectively, can carry out cephalometry and shooting operation.A large amount of experiments show, adopt the video of this method production, and the edge line of lateral symmetry structure can overlap fully, the measurement point and the angle that can show the soft or hard tissue clearly, and needed plane interested, obtain high-quality graphic materials, for diagnosis provides advantage.
Second kind of embodiment: Figure 12 introduced the adjustment mode of another kind of seat 1 backrest height.As shown in the figure, the backrest 5 of this seat is a kind of hydraulic mechanism that is made of piston 25, cylinder sleeve 26, oil pipe 27 and controller 28, the controller 28 here comprises hydraulic units such as fuel tank, oil pump and allotter, the handle of steering controller 28, the just lifting stably of seat 1 backrest height, thereby the height of adjustment cephalometer 2.
Certainly, this hydraulic mechanism also can replace with pneumatic mechanism.
The chair lower limb 3 adjustable for height seats 1 that the third embodiment: Figure 13 has introduced.As seen from the figure, chair lower limb 3 is hydraulic mechanism or the pneumatic mechanisms that are made of piston 25, oil cylinder 26 and oil pipe 27 and controller 28, the handle of steering controller 28, and chair lower limb 3 height just can change stably, can drive the lifting of cephalometer 2.In order to keep the stability of seat, the outer surface that also is provided with one section sliding sleeve 29 and oil cylinder 26 below seat 4 matches and slides up and down.This sliding sleeve can adopt slide block chute etc. to prevent the mechanism that rotates.
The 4th kind of embodiment: as seen from Figure 14, universal wheel 32 is equipped with in chair lower limb 3 lower ends at seat 1, the mode of universal wheel 32 has many kinds, a kind of universal wheel of expression is provided with spherical wheel of rotating around horizontal wheel shaft among the figure, the setting rotating shaft that horizontal wheel shaft is connected can be rotated around vertical axis, can synthesize the rotation of any direction.It is convenient to adopt this universal wheel that this positioning chair is moved.
Because this seat should not change behind the location, so added locking device on universal wheel 32.This locking device also can have many kinds.What exemplify among the figure is a kind of, mainly is made of securing rod 33, return spring 34, pedal 35, pintle hook lock 36 etc.As shown in figure 14, step on pedal 35 when needs lock, the elastic force that securing rod 33 overcomes return spring 34 moves down along the inclined-plane of pintle hook lock 36 and compresses spherical the wheel, makes it and can not rotate.When needs are walked, as shown in figure 15, foot push away pintle hook lock 36 overcome the top spring pressure and in contract, securing rod 33 is up under the promotion of return spring 34, and decontrols spherical the wheel.Securing rod 33 is promptly blocked by another inclined-plane of pintle hook lock 36 after up one section and stops.
Certainly, this universal wheel also is applicable to other forms of seat 1 as the chair lower limb 3 among the third embodiment, can support below by three universal wheels.The rest may be inferred, repeats no more.
