Description
Technical field
This utility model relates to CBCT equipment, particularly relates to a kind of CBCT mechanism with multiple degree of freedom.
Background technology
CT and ComputedTomography, means CT scan, and it utilizes ray generator and detector to make profile scanning around a certain position of human body.And CBCT and ConebeamCT, or be called conical beam CT, be a kind of equipment utilizing cone beam throwing to shine computer restructuring fault image, its principle does annular DR(digital throwing around throwing according to body with lower quantity of X-rays X by ray (as x-ray) generator to shine).The throwing that CBCT obtains data is diverse according to principle and conventional sector scanning computed tomography, and the algorithm principle of later stage computer restructuring has similar part.
Existing CBCT equipment is special particular device, such as oral cavity CBCT, its frame is fixedly installed in ground, frame is fixedly equipped with an immovable C-arm, the C shape two ends of C-arm are equipped with ray generator respectively and are received the detector of ray, and C shape inner chamber is the size that can stretch into for head, this kind of equipment can only head and oral cavity, its scope of application and can detection range narrower, and operation inconvenience, easily and patient collide.
Summary of the invention
This utility model aims to provide a kind of CBCT mechanism with multiple degree of freedom, to improve its scope of application and operation ease.
Multiple degrees of freedom CBCT mechanism described in the utility model, comprise C-arm, be arranged at the detector of the ray generator at C-arm two ends and reception ray, there is the base that can rotate around own axes, the large arm on base is articulated with one end, the forearm that can rotate around own axes is then articulated with the other end of large arm, and forearm connects C-arm and drives it to rotate; Base is fixed on ceiling, wall or column, and the jointed shaft of two hinged ends of large arm is parallel to ceiling or wall.
Multiple degrees of freedom CBCT mechanism described in the utility model, base and forearm all can rotate around own axes, and connected by large arm between both, and large arm rotating hinge spindle is parallel to the Plane of rotation of base, multivariant rack construction is formed with this, and then drive C-arm and on checkout gear realize multiple degrees of freedom, multi-angle and multipoint location, meet the needs of different test item, simultaneously, the C shape inner chamber of C-arm can be increased, to meet breast portion, waist, the detection of buttocks or leg position, its scope of application is greatly improved, and this mechanism is by the transmission of multiple degree of freedom, make operating process convenient, accurately with quick.

Detailed description of the invention
A kind of multiple degrees of freedom CBCT mechanism, comprise C-arm 5, be arranged at the detector 6 of the ray generator 7 at C-arm two ends and reception ray, there is the base 1 that can rotate around own axes, the large arm 2 on base is articulated with one end, the forearm that can rotate around own axes 4 is articulated with the other end of large arm, and forearm connects C-arm and drives it to rotate; Base is fixed on ceiling, wall or column, and the jointed shaft of two hinged ends of large arm is parallel to ceiling or wall.
As shown in Figure 1, 2, base is fixedly installed on ceiling, C-arm is then installed on forearm and with its motion, ray generator is equipped with in one end of C-arm inner chamber, and side's cone beam 8(naked eyes that it sends are invisible) project on the detector of the other end through human body.
As shown in Fig. 3,4,5, base 1 comprises hard-wired bedplate 11, and the rotating seat 13 bedplate being equipped with base electric rotating machine 12 and rotating with base electric rotating machine, also has the cable interface assembly 14 being communicated with internal circuit and external power source.The large arm oscillating motor 21 driving large arm to rotate is equipped with in the side that large arm 2 is connected with base 1.Be connected by joint elbow unit 3 between large arm 2 with forearm 4, comprise the stiff end be fixedly installed in large arm, and driven by joint elbow oscillating motor 31 and the swinging end fixed with forearm.Forearm 4 comprises the stiff end fixed with joint elbow unit 3, and is driven by forearm electric rotating machine 41 and the round end fixed with C-arm 5.The swing of the rotation of base, the swing of large arm, forearm, the rotation of forearm are controlled by base electric rotating machine, large arm oscillating motor, joint elbow oscillating motor and forearm electric rotating machine respectively, these motions can control respectively, also can cooperatively interact control, makes the position adjustments of this mechanism more quick and easy.
As shown in Figure 6, the multiple degrees of freedom CBCT mechanism of left figure, by the driving of each motor, can drive C-arm to be converted to the state of right figure.In addition, various states as shown in Figure 7 can also be converted to.Fig. 8-11 then illustrate work comprise stand, sitting, the different operating state that couches.
Above-mentioned illustrated multiple degrees of freedom CBCT mechanism, floor installation, in the top of ceiling or support, in addition also can be arranged on wall, now can be obtained by each view 90-degree rotation; Base can also be arranged on column or fixed support.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
