Abstract
The utility model relates to an arm C structure in the field of medical apparatus and instruments. The arm C structure comprises a machine frame, a probe, a transmission mechanism and a driving mechanism, wherein the transmission mechanism comprises an inner guide rail and an outer guide rail, and the inner guide rail and the outer guide rail are both arc-shaped and are fixed on the machine frame at the positions of concentric circles. The arm C structure achieves non-full-circle collection motion, is relatively simple in structural design, is high in motion accuracy, and is high in safety.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of C arm configuration of medical instruments field.
Background technology
At medical instruments field, in the x-ray imaging instrument, in order to realize non-full circle collection campaign, need to use the C arm configuration.
Usually the C arm configuration adopts roller to be combined with cirque structure, perhaps adopts multiaxis aggregate motion structure.
But, movement locus and the run location required precision of some medical apparatus and instruments probe are higher, roller structure is difficult to satisfy the requirement of Special medical equipment C arm configuration, and the general more complicated of multiaxis aggregate motion structure, movement combination need to be considered more axle matching problem etc., cost is higher, and safety is not high.
Summary of the invention
For the above-mentioned deficiency of prior art, this utility model provides a kind of C arm configuration, and this structure not only can realize non-full circle collection campaign, and structural design is relatively simple, and kinematic accuracy is high, and is safe.
The technical scheme that this utility model is taked is: a kind of C arm configuration is provided, comprise frame, probe, drive mechanism and driving mechanism, it is characterized in that: described drive mechanism comprises interior guide rail and outer guide, and described interior guide rail and described outer guide are arc and are fixed on the described frame with concentrically ringed position;
Further, described driving mechanism comprises work chain and chain for subsequent use, and described work chain and described chain for subsequent use distribute along C shape arm configuration side by side, and the length of described chain for subsequent use is greater than described work chain;
Further, described drive mechanism also comprises moving slide block, and described moving slide block is hinged with described interior guide rail and described outer guide respectively;
Further, described chain for subsequent use is provided with regulating wheel.
Compared with prior art, C arm configuration of the present utility model has the following advantages:
1) adopt two concentric arcs guide rail structures, not only realized non-full circle collection campaign, and simple in structure, the running orbit precision is higher;
2) adopt chain to drive and self-locking speed-down machine structure, can guarantee to stop immediately at an arbitrary position when probe runs into emergency case, if the work chain ruptures suddenly, chain for subsequent use works, thereby the assurance probe can not fall suddenly and the patient is caused personal injury;
3) driving mechanism adopts this soft drive of chain, and is simple in structure, and operation sound is lower, and requirement on machining accuracy is low, and cost is lower.

The specific embodiment
Below in conjunction with accompanying drawing C arm configuration of the present utility model is described in detail.
As shown in Figure 1, C arm configuration of the present utility model comprises frame 1, probe 10, drive mechanism and driving mechanism.
Drive mechanism comprises interior guide rail 2, outer guide 3 and moving slide block 5.The shape of interior guide rail 2 and outer guide 3 is arc, and these two guide rails are fixed on the frame 1 with concentrically ringed position.Probe 10 is connected and fixed with moving slide block 5, and moving slide block 5 is hinged with interior guide rail 2 and outer guide 3 respectively, and along guide rail movement.Because the shape of interior guide rail 2 and outer guide 3 is arc, so not only can realize non-full circle motion, and the constriction of reduction of patient effectively.Article two, guide rail is fixed on the frame with concentrically ringed position, has effectively reduced 10 laterally offsets that produce of popping one's head in when single guide rail slides, the positional precision when having guaranteed to pop one's head in 10 motion.In addition, moving slide block 5 adopts articulated structure to be connected with two guide rails, has avoided the jam that the position error causes that installs and fixes of two guide rails, has further improved the positional precision of 10 motions of popping one's head in.
Driving mechanism adopts the motor reducer 6 with self-locking to drive work chain 7 and chains for subsequent use 8, and then actuation movement slide block 5 is done non-full circle along two arc- shaped guide rails 2,3 track and moved.As shown in Figure 2, work chain 7 and chain for subsequent use 8 distribute along C shape arm configuration side by side, and the movement locus by supporting roller 9 change chains interferes to prevent chain and frame 1 or other parts.In order to improve safety, guarantee to stop immediately at an arbitrary position when probe 10 runs into emergency case, and do not fall suddenly, so the mode that adopts two chains to drive simultaneously.In use, the regulating wheel 4 that is fixed on the frame 1 by adjusting is adjusted to length greater than work chain 7 with chain 8 for subsequent use so that when day-to-day operation chain 8 for subsequent use stressed getting final product slightly.If work chain 7 ruptures suddenly, chain 8 for subsequent use will replace work chain 7, to keep the relative position of probe 10.Owing to adopt the motor reducer 6 with self-locking to drive, guaranteed power failure, when motion stops etc. under the state probe can keep resting state.
