Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of CT equipment based on C-arm.
Background technology
The CT equipment of C-arm is a kind of conventional medical test equipment, the CT equipment of this C-arm in the imaging of the center of grade and
Because central point is fixed has its own advantage during three-dimensional reconstruction, therefore it is widely used in orthopaedics, Pain Management, tumour
In the various operations of the section office such as section, gynaecology, Urology Surgery.
At present, the CT equipment mainly includes apparatus body, C-arm, ray source and Imaging Plate；C-arm is slided and set
In apparatus body, so that C-arm can circumferentially be slid with relative device body, ray source is oppositely arranged with Imaging Plate, respectively
It is arranged at the both ends of C-arm opening.Ray source is usually spot light, and spot light can launch cone-shaped beam, existing skill
The most-often used spot light of art is X-ray spot light.
When the CT equipment when in use, object to be detected is placed in inside C-arm, and the X-ray that spot light sends is through tested
After surveying object, the image at certain visual angle is molded on Imaging Plate.When the centers such as the CT equipment are imaged, object to be detected is in solid
Determine exposure position, the picture visual angle size that so exposure is obtained is excessively single, and detection position local location is not obvious.Therefore in order to gram
Drawbacks described above is taken, prior art has also carried out following improvement to CT equipment.
Drive shaft is set on apparatus body, and driving C-arm can be along the horizontal direction of opening direction, vertically phase
To motion, when being adjusted to detection site local location visual angle, by adjusting C-arm horizontal direction, vertically side simultaneously
To with circumferential sliding, and then adjust exposure center point so that obtain visual angle change.
The mode at above-mentioned adjustment visual angle is, it is necessary to adjust C-arm level, vertical and circumferential position simultaneously in the prior art
Put, that is, need by multijoint control to realize the multi-axis actuation of C-arm, necessarily cause CT device structures in the prior art more multiple
It is miscellaneous, and the horizontally and vertically position of real-time regulation C-arm is required in C-arm rotation process, control also complex.
Therefore, how a kind of simple structure and the simple CT equipment of both view angle adjustment are provided, be those skilled in that art urgently
Technical problem to be solved.

Specific embodiment
For CT equipment in the prior art described in background technology adjust visual angle when, it is necessary to multi-axis actuation is adjusted knot
Structure and the more complicated technical problem of control, the present invention has made intensive studies, and on the basis of numerous studies, looks for another way
Propose the technical scheme for solving above-mentioned technical problem.
In order that those skilled in the art more fully understands technical scheme, it is below in conjunction with the accompanying drawings and specific real
The present invention is described in further detail to apply example.
Refer to Fig. 1 and the structure that Fig. 2, Fig. 1 are the CT equipment based on C-arm in a kind of specific embodiment of the invention is shown
It is intended to；Fig. 2 is to install the close-up schematic view of the first regulating member position in Fig. 1.
The CT equipment based on C-arm provided in the present invention mainly includes apparatus body 1, C-arm 2, the and of ray source 3
Imaging Plate 4.The major function of apparatus body 1 has two aspects：Firstth, for the installation of miscellaneous part provides installation foundation, and have
There is the mounting structure being engaged with external environment, be installed in external environment with stabilization；Secondth, supporting role, i.e. equipment body
With needed for certain intensity satisfaction support of each parts thereon.
Primary structure and material on equipment body may be referred to prior art, not do specific introduction herein.
C-arm 2 is circumferentially rotated and is supported on apparatus body 1, that is to say, that C-arm 2 can be with along the circumference of apparatus body 1
With respect to reciprocating rotation.Realize that C-arm 2 and apparatus body 1 there are diversified forms with respect to the structure of reciprocating rotation, for example：Apparatus body 1
Both apparent surfaces of C-arm 2 one of which is provided with chute, another one is provided with the slide rail being engaged with chute, that is, sets
Slide rail or chute can be set on standby body 1, correspondingly, chute or slide rail are set in C-arm 2.Be given in Fig. 1 in C-arm 2
The specific embodiment of chute 21 is set.Specifically, support segmental arc can be set on apparatus body 1, the shape of segmental arc is supported
Shape matches with the outer surface of C-arm 2, and slide rail or chute are arranged on support segmental arc.
In addition, CT equipment also includes two groups of Timing Belt and drive devices for being respectively used to pull C-arm 2 to rotate and reverse,
I.e. CT equipment include first driving means and by first driving means drive the first Timing Belt, and the second drive device and by
The second Timing Belt that second drive device drives, first driving means the first Timing Belt of driving can realize that C-arm 2 is rotated forward, the
Two groups of drive device second Timing Belts of driving can realize the reversion of C-arm 2.C-arm 2 is rotated clockwise herein is defined as just
Turn, rotate counterclockwise and be defined as reversion.
