Wherein, utilize motor to drive described compressorium to move up and down, when pressure arrives default, pressure transducer feedback signal, described motor stalls, brakes simultaneously.
When needs are manually oppressed, described motor stalls, keep braking by brake, rotate described hand wheel component, then described plate for forcing assembly moves on described chain drive assembly, realizes the action of manually compressing.
As seen from the above technical solution provided by the invention, described compressorium comprises Bidirectional non-return device, hand wheel component, chain drive assembly and plate for forcing assembly, the driving shaft of wherein said Bidirectional non-return device connects described hand wheel component, driven shaft connects described chain drive assembly, utilizes this Bidirectional non-return device to realize adopting manually compressing when motor stalls; Described plate for forcing assembly to be connected with frame by two axis of guide and linear bearing assembly and to realize elevating movement, and electric transmission form is chain drive, and pressure transducer is arranged in described plate for forcing assembly; The driven shaft of described Bidirectional non-return device and described plate for forcing assembly are connected to form one structure, and are slowed down by one-level gear drive and level synchronization V belt translation, realize the needs of manually compressing fine setting.This compressorium according to the needs of clinical pendulum bit manipulation, freely can switch electronic or manually oppresses pattern, electronic and manual compressing is combined, and makes operation doctor react adjustment pressure size in time according to patient, brings more comfortable experience to patient.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 provides the compressorium structural representation of digital flat panel mammary machine for the embodiment of the present invention;
Fig. 2 is the structural representation of Bidirectional non-return device described in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Compressorium described in the embodiment of the present invention achieves manually compressing superposition in electronic compressing movable basis and forms compound motion.Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail, be illustrated in figure 1 the schematic diagram that the embodiment of the present invention provides the compressorium of digital flat panel mammary machine, described compressorium mainly comprises Bidirectional non-return device 8, hand wheel component 6, chain drive assembly 4 and plate for forcing assembly 10, and include motor 1 further, brake 2, linear bearing assembly 3, support wallboard 5, hand gear mechanism 7, pressure transducer 9 and driven sprocket assembly 11, wherein concrete structure is:
The driving shaft of Bidirectional non-return device 8 connects described hand wheel component 6, and driven shaft connects described chain drive assembly 4, utilizes this Bidirectional non-return device 8 to realize adopting manually compressing when motor 1 stops operating;
Described plate for forcing assembly 10 to be connected with frame by two axis of guide and linear bearing assembly 3 and to realize elevating movement, and electric transmission form is chain drive, and pressure transducer 9 is arranged in described plate for forcing assembly 10;
The driven shaft of described Bidirectional non-return device 8 and described plate for forcing assembly 10 are connected to form one structure, and are slowed down by one-level gear drive and level synchronization V belt translation, realize the needs of manually compressing fine setting.
Specifically, be illustrated in figure 2 the structural representation of Bidirectional non-return device described in the embodiment of the present invention, Fig. 2 comprises back-up ring 1, bearing 2, driven shaft 3, roller 4, spring 5, driving shaft 6 and fixing outer shroud 7, wherein: fixing outer shroud 7 is fixed, when driving shaft 6 is clockwise or when rotating counterclockwise, groove face promotes roller 4, make it stressed to depart from outer shroud endoporus, drive driven shaft 3 also synchronous axial system; And when driven shaft 3 receives moment of face effect, roller 4 by spring 5 tightly withstand on outer shroud endoporus, form very large moment of friction, make driven shaft clockwise, all can not rotate counterclockwise.
In specific implementation process, when carrying out electronic compressing, by the driven shaft of described Bidirectional non-return device, described plate for forcing assembly being become a rigid body, realizing compressing by described chain drive Component driver;
Wherein, utilize motor to drive described compressorium to move up and down, when pressure arrives default, pressure transducer feedback signal, described motor stalls, brakes simultaneously.Specifically, when pressing close-table compressing lifting button or backpedalling brake switch, compressing motion starts, the motor stalls when release button, and can preset pressure, and motor stalling when pressure arrives, brakes and keep pressure.
When needs are manually oppressed, described motor stalls, braking is kept by brake, handwheel and Bidirectional non-return device initiatively axle head are connected, rotating handwheel can drive driven end to move, then through level synchronization V belt translation, realizes compressorium and creep on chain, now chain is static relative to compressorium, and compressorium and chain realize relative motion.
As can be seen here, first adopt electric model to drop to plate for forcing as far as possible close to patient's chest tissue, or be urged to less pressure, then carry out the fine setting of oppressive force with manual mode.Because manual mode adjustment oppressive force is finer and smoother, operation doctor can be made to react adjustment pressure size in time according to patient, make patient in physical examination, obtain more comfortable experience.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
