Description

Technical Field

[0001] This utility model relates to the field of dental CBCT devices, and more particularly to a dental CBCT device. Background Technology

[0002] Because CBCT imaging of the oral cavity takes time, patient movement, whether voluntary or involuntary, can disrupt the consistency of the projection data, resulting in various artifacts in the reconstructed images and affecting the doctor's diagnosis. To avoid or reduce artifacts, a jaw rest is often used to immobilize the patient's head.

[0003] In existing dental CBCT equipment, both the U-arm and jaw support are mounted on a lifting column. Due to the poor rigidity of the lifting column, the U-arm is not stable enough during rotation, which reduces image quality. Furthermore, since the patient's head is supported on the jaw support, the force generated by the patient's movement is also transmitted to the lifting column through the jaw support, which in turn affects the stability of the U-arm rotation, reduces image quality, and increases the difficulty of image processing.

[0004] Based on the above-mentioned technical problems, this application proposes an oral CBCT device. Utility Model Content

[0005] The purpose of this utility model is to provide an oral CBCT device to solve the technical problems mentioned in the background art. This purpose is achieved through the following technical solution:

[0006] An oral CBCT device includes a main column, a lifting seat, and side columns. A crossbeam is provided on the top of the main column, and a U-arm is rotatably mounted on the lower end face of the crossbeam. The U-arm is used for CBCT imaging. The lifting seat is located below the U-arm. The side columns are fixed to one side of the lifting seat, and a positioning component is installed on the upper end of the side columns. The positioning component extends through the crossbeam to the imaging area of ​​the U-arm.

[0007] Furthermore, the dental CBCT equipment also includes a base, with the main column, lifting seat, and side columns all fixed on the base.

[0008] Furthermore, the positioning element is a jaw support.

[0009] Furthermore, a headrest is installed at the lower end of the crossbeam, and the distance between the headrest and the chin rest is adjustable.

[0010] Furthermore, the crossarm is connected to the side column via a horizontal rotating joint.

[0023] To better understand the above technical solutions, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, will illustrate the technical solutions. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] like Figure 1 The dental CBCT device shown includes a base 1, a lifting seat 2, a main column 3, a U-arm 4, and a side column 5. The base 1 is fixedly installed on the ground. The lifting seat 2 is an electrically driven lifting seat and is installed in the middle of the base 1. The main column 3 is vertically installed on the rear side of the base 1, and the side column 5 is vertically installed on the left side of the base 1.

[0025] like Figure 1 As shown, a crossbeam 31 is mounted on the top of the main column 3, extending forward above the lifting seat 2. A U-arm 4 is rotatably mounted on the underside of the crossbeam 31. A connecting shaft (not shown) is vertically fixed to the lower end face of the crossbeam 31. The U-arm 4 includes a rotating arm 41, with a radiation source 42 and a detector 43 mounted opposite each other at both ends. The radiation source 42 emits X-rays, and the detector 43 receives them. The middle of the rotating arm 41 is rotatably connected to the connecting shaft via a bearing. A motor drive assembly is installed in the crossbeam 31, driving the rotating arm 41 to rotate around the connecting shaft, allowing the radiation source 42 and detector 43 to perform a surround imaging of the patient's head, completing a three-dimensional image of the patient's face.

[0026] like Figures 1-4 As shown, the lower end of the side column 5 is fixedly connected to the base 1. A horizontal arm 6 is connected to the upper side of the side column 5 via a horizontal rotating joint 51. The horizontal arm 6 extends to the front of the lifting seat 2, and a chin rest 7 is installed at the end of the horizontal arm 6. The chin rest 7 is located below the imaging area of ​​the U-arm 4. A locking mechanism is installed at the horizontal rotating joint 51, and a locking button 61 is installed on the horizontal arm 6 to control the locking mechanism, allowing the horizontal arm 6 to open or close to one side of the lifting seat 2 or close to the front of the lifting seat 2, thus facilitating patient entry and exit. A position sensor (not shown) is installed at the horizontal rotating joint 51. The position sensor can be a photoelectric switch, microswitch, Hall effect sensor, or proximity sensor, used to monitor the position of the horizontal arm 6 and interlock the horizontal arm 6 with the U-arm 4 through a program. When the horizontal arm 6 is in the open / closed state, the U-arm 4 cannot operate to avoid injury to personnel or damage to the equipment.

[0027] Preferably, the horizontal rotation joint 51 is an electric joint, which can change the position of the horizontal arm 6 through the motor, thereby improving the ease of use.

[0028] Preferably, a control panel 8 is installed at the top of the side column 5. The control panel 8 is a physical button or a touch screen. The control panel 8 can be used to raise and lower the seat 2, rotate the U-arm 4, or swing the horizontal arm 6.

[0029] like Figure 1-3As shown, a connecting plate 91 is fixed at the lower end of the connecting shaft. A slot in the front-to-back direction is opened on the lower end face of the connecting plate 91. A headrest 9 is movably installed in the slot. The distance between the headrest 9 and the chin support 7 can be adjusted by moving the headrest 9.

[0030] When using it, firstly, as Figure 2 As shown, rotate the horizontal arm 6 to the open position, and after the patient sits on the lifting seat 2, control the lifting seat 2 to rise so that the patient's chin is at the same height as the jaw support 7.

[0031] Then, as Figure 3 As shown, rotate the horizontal arm 6 to the closed position, place the patient's chin against the jaw support 7, and make a slight adjustment to the height of the lifting seat 2 to make the patient more comfortable. Adjust the head support 9 forward and fix it so that the patient's head is fixed between the head support 9 and the jaw support 7.

[0032] Finally, U-arm 4 was activated to perform CBCT imaging of the patient's mouth and face.

[0033] The technical solutions provided in this application have at least the following technical effects or advantages:

[0034] 1. By mounting the U-arm on a fixed main column, the support rigidity of the U-arm is ensured, the stability of the U-arm rotation is improved, and the image quality is enhanced.

[0035] 2. By mounting the jaw support on the side column, the influence of external forces on the main column is avoided, ensuring the stability of the U-arm rotation, improving image quality, and reducing the difficulty of image processing.
