[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figure 1-Figure 3As shown, an embodiment of the present invention provides a cervical vertebra rotation and reduction instrument capable of accurately reducing a patient's dislocated cervical vertebrae. The cervical vertebra rotation and reduction instrument comprises a seat 1 and a rotation and reduction device. The seat 1 is provided with a support 121, which is used to abut the patient's cervical vertebrae. For example, there are seven cervical vertebrae, numbered one through seven from top to bottom. For example, if the fifth cervical vertebra is dislocated relative to the sixth cervical vertebra, the support 121 abuts the sixth cervical vertebra, ensuring that the sixth cervical vertebra remains stable while the rotation and reduction device is rotating and reducing the patient's fifth cervical vertebra. Before reducing a patient's dislocated cervical vertebrae, the patient's head must be initially adjusted to an angle that facilitates rotation and reduction of the dislocated cervical vertebrae without damaging the patient's joints. The unlocking angles are divided into forward flexion, lateral flexion, and rotation. The forward flexion angle is generally 35°, the lateral flexion angle is generally 35°, and the rotation angle is generally 45°. After the initial angle (i.e., the joint unlocking angle) is adjusted, the support 121 is pressed against the cervical vertebra to perform a rotation operation on the patient's dislocated cervical vertebra. The rotation operation is to rotate the patient's head in a directional manner and pull it upward at the same time to reset the dislocated cervical vertebra.

[0033] The rotary lever reset device includes an adjustment component 2, a rotary lever reset component 3 and an occipital-mandibular-forehead fixation sleeve 4. The adjustment component 2 is arranged on the seat 1, the rotary lever reset component 3 is arranged at the output end of the adjustment component 2, and the occipital-mandibular-forehead fixation sleeve 4 is arranged at the output end of the rotary lever reset component 3. The adjustment component 2 can adjust the occipital-mandibular-forehead fixation sleeve 4 in the horizontal direction, the vertical direction and the direction around the axis of the adjustment component 2, that is, adjust the forward bending angle and the lateral bending angle of the patient's head. The rotary lever reset component 3 can adjust the occipital-mandibular-forehead fixation sleeve 4 in rotation, that is, adjust the rotation angle of the patient's head. After the adjustment component 2 and the rotary lever reset component 3 have made initial angle adjustments to the patient's head, the rotary lever reset component 3 can simultaneously rotate and lift the occipital-mandibular-forehead fixation sleeve 4, even if the patient's head is rotated and lifted, so as to reset the dislocated cervical vertebra. This structure can perform fixed-segment rotary lever reset according to the patient's first to seventh cervical vertebrae, and the rotation angle and lifting distance are precisely set to complete the rotary lever reset operation efficiently and accurately.

[0034] The cervical vertebra rotation and reduction instrument can perform reduction operations on patients' dislocated cervical vertebrae, making the operation controllable, automated, precise and standardized, safe and efficient, and greatly improving the success rate and safety of cervical vertebra reduction.

[0035] The function of the support 121 is to support the next cervical vertebra adjacent to the dislocated cervical vertebra so that the next cervical vertebra is stable and immobile. In order to make the support 121 more similar to finger operation, the support 121 is selected as a flexible clamping claw, which can simulate the movement of fingers to press the back of the patient's neck. The flexible clamping claw can be selected with four fingers, with the middle finger of the flexible clamping claw pressing against the cervical vertebra, and the fingers on both sides pressing the back of the neck, so that the flexible clamping claw provides a biomechanical pressure similar to that of the fingers, reducing the chance of injury caused by local pressure caused by hard objects and improving the comfort of reduction.

[0036] To more intuitively reflect the pressure of the support 121, a pressure sensor is provided on the surface of the support 121 that contacts the patient, which can monitor the pressure in real time according to different situations. A pressure threshold can also be set according to different situations to ensure that the pressure of the support 121 is within a certain range.

[0037] The top support 121 is set on the seat 1 through the sixth universal joint, and the sixth universal joint is slidably connected to the seat 1 through a slider, so that the top support 121 can be universally adjusted and the position can be adjusted left and right through the slider to adapt to different head and neck postures.

[0038] The occipital-mandibular-forehead fixation sleeve 4 is made of a hard material, with a soft spacer placed on the inner side that contacts the patient to ensure patient comfort. The occipital-mandibular-forehead fixation sleeve 4 includes a connecting portion 41, a front fixing portion 42 connected to the connecting portion 41, and a rear fixing portion 43. The output end of the rotary reset assembly 3 is fixedly connected to the connecting portion 41. The front fixing portion 42 is mounted on the patient's chin and face, and the rear fixing portion 43 is mounted on the back of the patient's head. The sizes of the front fixing portion 42 and the rear fixing portion 43 are adjustable to accommodate different patients and ensure a secure fit.

[0039] Continue to refer to Figure 1The adjustment assembly 2 includes an adjustment rod 21, which is connected to the seat 1 through a first universal joint. The adjustment rod 21 can realize universal rotation relative to the seat 1, and after the rotation adjustment of the adjustment rod 21 relative to the seat 1 is completed, the first universal joint can fixedly connect the adjustment rod 21 to the seat 1 to ensure that the adjustment rod 21 does not rotate relative to the seat 1; the output end of the adjustment rod 21 is provided with a mounting seat 2121, and the rotary lever reset assembly 3 is rotatably connected to the mounting seat 2121. The rotary lever reset assembly 3 can swing up and down relative to the mounting seat 2121, and after the rotary lever reset assembly 3 is adjusted, it can be fastened to the mounting seat 2121 through the first fastener. The structural adjustment rod 21 can swing up and down in the vertical direction through the first universal joint, and the rotary lever reset assembly 3 can swing up and down in the vertical direction on the mounting seat 2121. The adjustment rod 21 and the rotary lever reset assembly 3 simultaneously adjust the swing of the occipital-mandibular-forehead fixing sleeve 4 in the vertical direction to achieve the adjustment of the forward bending angle of the patient's head; and the adjustment rod 21 can also swing in the horizontal direction and rotate around the adjustment rod 21 itself as the axis through the first universal joint to adjust the swing and rotation of the occipital-mandibular-forehead fixing sleeve 4 in the horizontal direction, thereby achieving the adjustment of the lateral bending angle of the patient's head.

[0040] The adjustment assembly 2 also includes a first telescopic member 22 and a second telescopic member 23. The fixed end of the first telescopic member 22 is connected to the seat 1 via a second universal joint, and the output end of the first telescopic member 22 is connected to the side of the adjustment rod 21 via a third universal joint. The output end of the first telescopic member 22 can be extended or retracted relative to the fixed end to allow the adjustment rod 21 to swing horizontally, and after the first telescopic member 22 is adjusted, the position of the output end of the first telescopic member 22 can be locked; the fixed end of the second telescopic member 23 is connected to the seat 1 via a fourth universal joint, and the output end of the second telescopic member 23 is connected to the bottom end of the adjustment rod 21 via a fifth universal joint. The output end of the second telescopic member 23 can be extended or retracted relative to the fixed end to allow the adjustment rod 21 to swing vertically. In this structure, the first telescopic member 22 and the second telescopic member 23 can achieve more precise swinging of the adjustment rod 21 and are easy to adjust. Accurate adjustment can be completed by electrically controlling the first telescopic member 22 and the second telescopic member 23. It can be understood that the first universal joint, the second universal joint, the third universal joint, the fourth universal joint and the fifth universal joint can all realize movement in any direction. Therefore, the adjustment rod 21 always has the freedom to rotate around its axis.

[0041] In order to adapt to patients of different body shapes, such as patients with different fat and thin, continue to refer to Figure 2The adjustment rod 21 includes a first rod 211 and a second rod 212. The first rod 211 is connected to the seat 1 through a first universal member, and the first rod 211 is provided with a sliding cavity, and the second rod 212 is slidably set in the sliding cavity. The second rod 212 slides in the sliding cavity to move the pillow-jaw-forehead fixing sleeve 4 toward or away from the seat 1, and after adjustment, the second rod 212 and the first rod 211 are fixed by a second fastener.

[0042] The first fastening member and the second fastening member are both screws.

[0043] The adjustment component 2 also includes a third telescopic member 24, the fixed end of the third telescopic member 24 is connected to the first rod 211, and the output end is connected to the second rod 212. The output end of the third telescopic member 24 can drive the second rod 212 to slide in the sliding cavity, so that the pillow, jaw and forehead fixing sleeve 4 can move toward or away from the seat 1 more conveniently.

[0044] Optionally, the first telescopic member 22 , the second telescopic member 23 and the third telescopic member 24 may be hydraulic cylinders, screw-nut structures or electric push rods.

[0045] Optionally, the rotary lever reset assembly 3 includes a rotary servo motor and a linear servo motor. The fixed end of the rotary servo motor is arranged on the mounting seat 2121, and the fixed end of the linear servo motor is arranged at the output end of the rotary servo motor. The occipital jaw and forehead fixation sleeve 4 is connected to the output end of the linear servo motor. The rotary servo motor of this structure drives the linear servo motor to rotate, thereby realizing the rotation of the occipital jaw and forehead fixation sleeve 4. The output end of the linear servo motor can drive the occipital jaw and forehead fixation sleeve 4 to move upward along its axis. When adjusting the initial angle, the rotary servo motor can drive the occipital jaw and forehead fixation sleeve 4 to rotate so that the patient's head reaches the required rotation angle; during the rotary lever reset operation, the rotary servo motor and the linear servo motor act simultaneously to realize the simultaneous rotation and lifting of the occipital jaw and forehead fixation sleeve 4. It can be understood that the rotary lever reset operation is to simultaneously pull the patient's head diagonally upward when the rotation is reset.

[0046] In another optional embodiment, the rotary wrench reset assembly 3 may also be a single-axis robot, which can simultaneously realize the operations of rotation and linear movement.

[0047] In order to fix the patient on the chair 1, a fixing belt 122 is provided on the chair 1. When the patient sits on the chair 1, the fixing belt 122 can fix the patient on the chair 1. Furthermore, two fixing belts 122 are provided, and the two fixing belts 122 are arranged at intervals in the vertical direction.

[0049] Furthermore, the base 11 includes a bottom bracket 111, a seat cushion 112 and four adjustable legs 113. The seat cushion 112 is arranged on the bottom bracket 111. The bottom bracket 111 includes four fixed legs. The four fixed legs are welded together by an intermediate tube. The four fixed legs are arranged flush with one end facing the ground, and two adjacent fixed legs protrude from the seat cushion 112 at the end facing away from the ground. The four adjustable legs 113 are respectively adjustably arranged at one end of the four fixed legs facing the ground. By adjusting the position of the adjustable legs 113 in the fixed legs, the height adjustment of the bottom bracket 111 can be achieved; the backrest 12 is adjustably arranged in the two fixed legs protruding from the seat cushion 112 to achieve the height adjustment of the backrest 12.

[0050] The backrest 12 further includes a plurality of I-shaped brackets. The I-shaped bracket at the bottom is plugged and fixed with the two sleeves, and adjacent I-shaped brackets are plugged and fixed to each other, so that the height direction of the backrest 12 is adjustable.

[0051] More specifically, the multiple I-shaped brackets include a first bracket 123, a second bracket 124, a third bracket 125, a fourth bracket 126, and a fifth bracket 127. The two mutually parallel lower plug-in tubes of the first bracket 123 have their ends adjustably inserted into the two top sleeves; the two mutually parallel lower sleeves of the second bracket 124 are respectively sleeved on the ends of the two lower plug-in tubes facing away from the top sleeves, and the position of the second bracket 124 relative to the first bracket 123 is adjustable; the two mutually parallel middle plug-in tubes of the third bracket 125 have their ends adjustably inserted into the two lower sleeves of the second bracket 124 and the two mutually parallel upper sleeves of the fourth bracket 126; and the two mutually parallel upper plug-in tubes of the fifth bracket 127 have their positions adjustably inserted into the two upper sleeves. These multiple I-shaped brackets enable more flexible height adjustment of the backrest 12.

[0052] The top support 121 is set on the third bracket 125. The first bracket 123, the second bracket 124 and the third bracket 125 can be adjusted to each other in the vertical direction, so that the vertical adjustment range of the top support 121 is larger, and it can be abutted and fixed according to the cervical dislocation in different positions of patients with different heights.
