[0002] Oral CT can provide feedback on tissue conditions from a three-dimensional perspective and can detect lesions that cannot be detected by the projection angle of oral X-rays or are more subtle. The three-dimensional reconstruction effect of oral CT can accurately evaluate the condition of bone tissue and mandibular joints, assisting doctors in pre-operative plan design and post-operative scientific evaluation.

[0003] Existing dental CT equipment generally operates in a vertical rotation axis manner, which usually has the following defects: 1. The stacking of structures in the height direction will cause the equipment to be too tall, resulting in poor structural stability of the entire equipment, so the equipment needs to be reinforced by nailing on the wall; 2. The vertical rotation axis method makes the use scenario of the equipment single, and users can only sit or stand to shoot, which is difficult to expand to other application scenarios. Utility Model Content

[0004] The X-ray imaging device provided by the utility model, and the oral CT including the X-ray imaging device, can realize horizontal rotation of the imaging device to increase the stability and usage scenarios of the entire device.

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] In order to achieve the above purpose, the embodiment of the present utility model adopts the following technical solutions: Figure 1 、 Figure 2 , an X-ray imaging device, includes a column 10, and further includes a driving source, a C-arm 30 and an imaging device, wherein the driving source is arranged on the column 10 in the form of a horizontal distribution of its output shaft axially, and the C-arm is arranged on the output shaft of the driving source, and the imaging device includes a detector 410 and a radiation source 420 arranged in a relative form on the side wall of the C-arm. When in use, the output shaft of the driving source is distributed along the horizontal line direction, so that when the driving source rotates, it can drive the C-arm and the imaging device thereon to rotate horizontally. Therefore, the horizontal arrangement of the output shaft of the driving source can reduce the stacking of the structure in the height direction, greatly reduce the height and volume of the structure, so as to improve the stability of the entire device; at the same time, the X-ray imaging device can also increase the use scenarios of the device, that is, the user can achieve the shooting purpose in a sitting position, a standing position, or a lying position, thereby increasing the applicability of the device.

[0030] Reference Figure 3 、 Figure 4As a preferred technical solution of this embodiment, the X-ray imaging device also includes a translation mechanism, which is used to drive the column 10 to perform linear displacement. Further, the translation mechanism includes a base plate 510 and a transverse movement component arranged on the base plate, and the transverse movement component includes a slide rail 521, a slide seat 522, a screw motor 523, a screw 524 and a nut seat 525. The slide rail 521 is fixed on the base plate 510, and the slide seat 522 is slidably arranged on the slide rail through a slider. The screw motor 523 is fixed on the base, and the screw 524 is arranged at the output end of the screw motor. The nut seat 525 is threadedly arranged on the side of the screw shaft, and the nut seat can move along the axial direction of the screw. At the same time, in order to drive the slide seat 522, the nut seat is fixedly connected to the slide seat 522. When in use, the screw is driven to rotate under the drive of the screw motor, and the screw then drives the nut seat to move along the axial direction of the screw, thereby driving the column to move horizontally through the nut seat.

[0031] The presence of the transverse movement component can work together with the driving source to superimpose the single rotational motion of the imaging device on the C-arm into a spiral motion of "rotation + translation".

[0032] Reference Figure 5 As a preferred technical solution of this embodiment, the driving source includes a driving motor 210, a reducer 220, a base 230 and a transmission housing 240. The driving motor 210 is arranged on the column 10, the reducer 220 is arranged at the output end of the driving motor, the base 230 is fixed to the side wall of the column, and the transmission housing 240 is rotatably arranged on the base, and the transmission housing is connected to the reducer through a transmission component. At the same time, the C-arm 30 is arranged at one end of the transmission housing 240 away from the base 230. Furthermore, in order to achieve the horizontal distribution of the output shaft of the driving source, the axial direction of the transmission shaft of the transmission housing is horizontally distributed. In this way, when the driving motor drives the reducer to work, it drives the transmission component to move, and then drives the transmission housing to rotate outside the base, thereby realizing the horizontal rotation of the C-arm and the imaging device thereon.

[0033] It should be noted that the base and the components thereon play the role of bearing the gravity of the C-arm and the torque generated by gravity, thereby achieving effective installation of the C-arm and the imaging equipment thereon.

[0034] Further, refer to Figure 5 The transmission assembly includes a driving gear 251 and a driven gear 252. The driving gear 251 is arranged at the output end of the reducer 220, and the driven gear 252 is arranged on the outer wall of the base 230, and the driven gear 252 is engaged with the driving gear. When in use, the driving gear is driven by the reducer to rotate, and the driving gear then drives the driven gear to rotate, thereby driving the transmission housing to rotate on the outer wall of the base.

[0035] Furthermore, in order to realize the effective rotation of the transmission housing 240 along the outer wall of the base 230, the transmission housing 240 is rotatably set on the outer wall of the base 230 through a tapered roller bearing 260. It should be noted that the tapered roller bearing is a double-row tapered roller bearing to improve the rotation stability of the transmission housing.

[0036] Further, refer to Figure 5 An inner end cover 270 is provided at the end of the base 230 away from the column 10, and the outer ring stop of the inner end cover is pressed onto the inner ring of the tapered roller bearing 260. At the same time, a connecting flange 280 is provided on the outer periphery of the inner end cover 270 at the end of the transmission housing 240 away from the base 230, and the inner ring stop of the connecting flange is pressed onto the outer ring of the tapered roller bearing 260. When in use, the base is sealed by the inner end cover, and the transmission housing is sealed by the connecting flange. The structure composed of the base, the transmission housing, the connecting flange and the inner end cover is used to jointly limit the axial position of the tapered roller bearing, so as to achieve effective installation and fixation of the tapered roller bearing.

[0037] During use, the driving motor 210 transmits power to the driving gear 251 through the reducer 220, and the driving gear 251 then drives the driven gear 252 to rotate, and the driven gear then drives the transmission housing 240 to rotate on the outer wall of the base 230, and then drives the C-arm 30 to rotate horizontally, and the C-arm then drives the detector 410 and the radiation source 420 thereon to scan the user's oral area, thereby realizing scanning imaging.

[0038] The present utility model also provides an oral CT, which includes the aforementioned X-ray imaging device. Since the aforementioned X-ray imaging device can realize horizontal rotation of the imaging device, the oral CT can reduce the stacking of the structure in the height direction, reduce the height and volume of the structure, and increase the stability of the equipment; at the same time, the user can use the oral CT in a sitting, standing, or lying position, thereby increasing the use scenarios of the equipment.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
