Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a radiology atlantoaxial joint imaging aid. Background Technology

[0002] The atlantoaxial joint is the joint formed by the first cervical vertebra (atlas) and the second cervical vertebra (axis) in the cervical spine. Located at the base of the skull between the atlas and axis, it includes the left and right lateral atlantoaxial joints and one median atlantoaxial joint. Movement of the atlantoaxial joint allows for head rotation. Common diseases related to the atlantoaxial joint include atlantoaxial dislocation, atlantoaxial asymmetry, atlantoaxial osteoarthritis, and atlantoaxial instability. These conditions can cause symptoms such as neck pain, limited range of motion, and nerve compression.

[0003] When the hospital uses a direct digital radiography (DR) system to examine the atlantoaxial joint, the patient needs to lean against the board, with the midsagittal plane of the skull perpendicular to the board and coinciding with the midline of the board. The head should be tilted back so that the line connecting the occlusal surface of the maxillary incisors to the tip of the mastoid process is perpendicular to the board. The mouth should be wide open, and the image must include the upper and lower edges of the first and second cervical vertebrae and have a clear atlantoaxial joint space. This operation is difficult to achieve by conventional positioning alone and usually requires repeated imaging, resulting in low imaging efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a radiology atlantoaxial joint imaging aid. In DR imaging, the angle of the subject's head tilting up and down can be controlled according to the imaging needs, thus solving the problem of difficult atlantoaxial joint imaging.

[0005] This utility model provides a radiology atlantoaxial joint imaging aid, including a head fixation mechanism, a support mechanism, a hanging component, a height adjustment mechanism, and an angle adjustment mechanism. The head fixation mechanism is connected to the support mechanism via a hinge shaft. The right side of the support mechanism is connected to the hanging component, which is connected to a flat panel detector.

[0006] The head-fixing mechanism includes a housing, a hand-tightening bolt, a front elastic washer, a slot, and a rear elastic washer. A hand-tightening bolt is located at the front of the housing, connecting to the front elastic washer inside the housing via a screw hole. The hand-tightening bolt adjusts the inward extension of the front elastic washer. The locking mechanism is adjusted according to the size of the examinee's head. A slot is located at the rear of the housing, and the rear elastic washer is fitted into the slot. The rear elastic washer is available in various thicknesses and can be replaced according to the size of the examinee's head.

[0007] The support mechanism includes two sets of triangular brackets, an upper crossbar, and a lower crossbar. The two sets of triangular brackets are connected by the upper crossbar and the lower crossbar. A set of triangular brackets is connected to each side of the housing by a hinge shaft.

[0008] The height adjustment mechanism includes a socket end, a connector, and a locking bolt A. Each set of triangular supports has a socket end at its upper end, with a connecting end connected above it. A connector is located below the connecting end, and the connector is fitted to the socket end. A locking bolt A is located on the side of the socket end. Lifting the connecting end upwards adjusts the height of the upper part of the triangular support. The locking bolt A secures or releases the connector from the socket end. The height adjustment mechanism can adjust the relative position of the head and the flat panel detector, thereby positioning the inspection area in a position favorable for detection by the flat panel detector.

[0009] The mounting component includes a connecting end, a locking bolt B, and a snap-fit ​​arm. The locking bolt B is located at the front of the connecting end. The locking bolt B passes through a screw hole on the connecting end and connects to the snap-fit ​​arm. The other end of the snap-fit ​​arm is bent downwards to snap onto the flat panel detector.

[0010] The angle adjustment mechanism includes a toothed block, a bidirectional motor, and a gear. The toothed block is located at the rear end of the housing. The lower crossbar is hollow, and a bidirectional motor is installed inside. The bidirectional motor drives the gear, which meshes with the toothed block. The bidirectional motor drives the gear to rotate, causing the toothed block to move up and down, thereby enabling the rear end of the housing to rotate upwards and downwards. This allows the examinee to tilt their head down or up at a certain angle to achieve the required body position for the examination.

[0011] The bidirectional motor is equipped with a remote control switch, which receives remote control signals through a signal receiving device to control the bidirectional motor.

[0012] The angle adjustment mechanism has an angle adjustment range of 30 degrees.

[0013] The bidirectional motor is powered by a rechargeable lithium battery, which is replaceable.

[0014] The beneficial effects of this utility model are as follows: the head fixing mechanism of this utility model can be adjusted and locked to different head sizes; the height adjustment mechanism can adjust the relative position of the head and the flat panel detector, so that the examination area is in a position that is conducive to the detection of the flat panel detector; the angle adjustment mechanism can enable the examinee to lower or raise their head at a certain angle to achieve the body position required for the examination.

[0015] The device provided by this utility model can solve the problem of low examination efficiency when hospitals perform atlantoaxial joint examinations. When using DR imaging, this device can be used to remotely control the angle of the subject's head tilting up and down according to the imaging needs, thus solving the problem of difficult imaging of the atlantoaxial joint.
