[0024] The embodiment of the present application provides a cervical vertebra extension position inspection device, solves the problem that the device for cervical vertebra extension position inspection in the prior art is not applicable to cervical vertebra extension position inspection, and in order to better understand the technical scheme of the present application, the above technical scheme will be described in detail below in combination with the drawings of the specification and the specific implementation manner.

[0025] The example discloses a cervical vertebra extension position inspection device, referring to Figures 1-6The device comprises a base 1, a lower limb supporting plate 2 fixed on the base 1, an upper limb supporting plate 3 installed on the end of the lower limb supporting plate 2, a driving mechanism 4 arranged on the back of the upper limb supporting plate 3 for supporting the upper limb supporting plate 3, and a clamping mechanism 5 arranged on the base 1 at the other end of the upper limb supporting plate 3 for fixing the head. The examination is performed by cooperation of the rotatable upper limb supporting plate 3 and the displaceable clamping mechanism 5, so that the neck of the patient is hyperextended, and a certain gap is left between the clamping mechanism 5 and the upper limb supporting plate 3, which can make the doctor better observe the physiological curvature of the patient in the hyperextended position of the cervical spine, and also facilitate the judgment of whether the patient has a position of pain and stiffness, thereby effectively assisting the doctor in diagnosing the disease and improving the diagnosis efficiency and accuracy.

[0026] The upper limb supporting plate 3 comprises a fixed plate 33 rotatably connected with the lower limb supporting plate 2, an extension shaft 32 movably arranged at the other end of the fixed plate 33, and an extension plate 31 fixed on the end of the extension shaft 32. The extension shaft 32 and the extension plate 31 can be used to make the device suitable for patients of different sizes.

[0027] The driving mechanism 4 comprises a fixed rod 46 fixed on the back of the fixed plate 33, a follower rod 44 rotatably installed on the fixed rod 46, and a positioning block 43 rotatably installed on the other end of the follower rod 44. The driving mechanism 4 further comprises a pair of limiting screws 45 rotatably installed on the base 1, a rotating disc 41 arranged on the end of the limiting screw 45, and a synchronous belt 42 sleeved between the rotating discs 41, one of the rotating discs 41 is further provided with a driving handle 411 for driving, and the positioning block 43 is threadedly sleeved on the limiting screw 45. The driving handle 411 is used to control the rotation of the rotating disc 41, thereby indirectly controlling the inclination angle of the upper limb supporting plate 3.

[0028] The clamping mechanism 5 comprises a sliding rail 51 arranged on the base 1, and a fixed assembly 52 movably arranged in the sliding rail 51. The fixed assembly 52 corresponds to the front of the upper limb supporting plate 3 and is at the same horizontal level with the upper limb supporting plate 3. The fixed assembly 52 comprises a fixed groove 521 arranged thereon, side plates 522 fixed on both sides thereof, a movable column 524 movably arranged in the side plates 522, a limiting plate 527 fixed on the outer end of the movable column 524, a limiting handle 528 arranged on the limiting plate 527, a clamping block 525 rotatably arranged on the inner end of the movable column 524 for clamping the head, and a plurality of protrusions 5251 arranged on the clamping block 525 for increasing friction. A limiting nut 526 is rotatably sleeved on the clamping block 525 for limiting, and a clamping spring 523 is sleeved on the movable column 524 between the limiting nut 526 and the side plate 522. The clamping force of the clamping block 525 on the head can be indirectly adjusted by rotating the limiting nut 526 to limit the clamping spring 523.

[0029] In the implementation of the device, the patient lies on the base 1 with the legs close together and placed on the lower limb support plate 2, and the upper body close together on the fixed plate 33. During this period, the doctor adjusts the distance between the telescopic plate 31 and the fixed plate 33 to make the upper end of the telescopic plate 31 level with the patient's shoulders, and fixes the telescopic plate 31 by fixing the telescopic shaft 32. After the patient lies down, the doctor manually pulls the limiting handle 528 on both sides of the fixing assembly 52, drives the clamping block 525 connected thereto to displace to both sides, and pushes the fixing assembly 52 forward to make the patient's head clamped between the clamping blocks 525 and leave a certain distance from the fixed groove 521 for head rotation. Then, the doctor slowly releases the limiting handle 528, and the clamping spring 523 sleeved on the movable column 524 reversely pushes the clamping block 525 to clamp and fix the head. The protrusion 5251 provided on the clamping block 525 is designed of soft rubber, which not only reduces the discomfort to the head, but also increases the friction between the clamping block 525 and the head to avoid the head from falling off the device during the examination. In addition, the doctor can also adjust the clamping force of the head according to the size of the patient's head shape and the angle of the cervical spine extension position. Specifically, the limiting nut 526 is turned to adjust the distance between the limiting nut 526 and the side plate 522 to adjust the elastic force of the clamping spring 523. The elastic force indirectly acts on the clamping block 525 through the side plate 522 to indirectly adjust the clamping force of the clamping block 525 on the head. After the head is fixed, the doctor turns the rotating disc 41 by holding the driving handle 411. The two rotating discs 41 rotate synchronously under the limitation of the synchronous belt 42. The rotating synchronous belt 42 drives the limiting screw 45 to rotate. The rotating limiting screw 45 drives the positioning block 43 sleeved thereon to displace along the limiting screw 45. The moving positioning block 43 indirectly drives the upper limb support plate 3 to rotate through the follow-up rod 44 and the fixed rod 46. The rotation of the upper limb support plate 3 can realize the rotation of the patient's upper body. Since the clamping block 525 is designed to be rotatable and the fixed area is the patient's head, the head rotates around the clamping block 525 and the fixing assembly 52 displaces forward while the patient's upper body rotates, so that the patient's cervical spine is extended at a certain angle. The doctor can observe the cervical spine between the clamping mechanism 5 and the upper limb support plate 3 to determine whether the physiological curve of the cervical spine changes. The doctor can also determine whether the patient has a painful or stiff area by pressing or touching the patient's cervical spine. The above examination can assist the doctor to more accurately determine the condition. At the same time, the doctor can also indirectly control the angle of the cervical spine extension position by controlling the rotation of the driving handle 411 to realize the all-around examination of the cervical spine extension position, which is more helpful for the analysis and diagnosis of the condition. During the examination, the patient's head is fixed by the clamping block 525 and also abuts against the fixed groove 521, which can avoid the instability of the head during the examination of the cervical spine extension position.After the examination is completed, the driving handle 411 is rotated to reset, and then the limiting handle 528 is pulled by two hands to separate the patient's head from the clamping mechanism 5.
