[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figure 1-3This embodiment provides a CT supine arm fixation bracket, which includes: a base plate 1, a side plate 2, a height adjustment assembly, a bidirectional drive assembly 4, a pair of arm support assemblies 5, and an angle adjustment assembly 6; the top of the base plate 1 is provided with a first groove 111; the side plate 2 is rotatably mounted on the top of the base plate 1, and a height adjustment area 21 is provided in the middle of the side plate 2, with the first groove 111 parallel to the side plate 2; the height adjustment assembly is slidably engaged in the height adjustment area 21, and the height adjustment assembly slides in the direction close to or away from the base plate 1. The component has a transverse sliding groove 311, which is arranged parallel to the first groove 111; a bidirectional drive assembly 4 is disposed in the first groove 111; one end of a pair of arm support assemblies 5 is movably engaged in the transverse sliding groove 311, and the other end of the pair of arm support assemblies 5 is respectively hinged to the bidirectional drive assembly 4, and the bidirectional drive assembly 4 drives the pair of arm support assemblies 5 to move towards or away from each other; an angle adjustment assembly 6 is disposed between the base plate 1 and the side plate 2, and the angle adjustment assembly 6 is used to adjust the included angle between the side plate 2 and the base plate 1. The angle adjustment assembly 6 and the height adjustment assembly are distributed on both sides of the side plate 2.

[0020] This invention provides a CT supine arm fixation bracket, comprising: a base plate 1, a side plate 2, a height adjustment assembly, a bidirectional drive assembly 4, a pair of arm support assemblies 5, and an angle adjustment assembly 6; a first groove 111 is formed on the top of the base plate 1; the side plate 2 is rotatably disposed on the top of the base plate 1, and a height adjustment area 21 is provided in the middle of the side plate 2, the first groove 111 being parallel to the side plate 2; the height adjustment assembly is slidably engaged within the height adjustment area 21, and the height adjustment assembly slides along the direction approaching or away from the base plate 1, the height adjustment assembly having a transverse sliding groove 3. 11. The transverse slide 311 is arranged parallel to the first groove 111; the bidirectional drive assembly 4 is disposed in the first groove 111; one end of a pair of arm support assemblies 5 is movably engaged in the transverse slide 311, and the other end of the pair of arm support assemblies 5 is respectively hinged to the bidirectional drive assembly 4, and the bidirectional drive assembly 4 drives the pair of arm support assemblies 5 to move towards or away from each other; the angle adjustment assembly 6 is disposed between the base plate 1 and the side plate 2, and the angle adjustment assembly 6 is used to adjust the included angle between the side plate 2 and the base plate 1. The angle adjustment assembly 6 and the height adjustment assembly are distributed on both sides of the side plate 2. This application rotatably mounts the side plate 2 on top of the base plate 1, and sets an angle adjustment component 6 between the base plate 1 and the side plate 2 to adjust the rotation angle of the side plate 2. Simultaneously, by placing the arm support assembly 5 between the height adjustment component and the bidirectional drive component 4, the bidirectional drive component 4 can drive the pair of arm support assemblies 5 to move relative to or away from each other, adapting to different patients' shoulder widths and body shapes. This ensures that when the patient extends their arms, both arms can be placed and fixed on the pair of arm support assemblies 5, preventing the patient's arms from moving during scanning, reducing motion artifacts, and improving image quality. Furthermore, when the angle of the side plate 2 is adjusted by the angle adjustment component 6, since the length of the arm support assembly 5 cannot be stretched or retracted, the rotation of the side plate 2 will cause the height adjustment component to move up and down, thereby adjusting the angle between the arm support assembly 5 and the base plate 1, thus achieving adjustment of the patient's arm span angle to meet the arm span needs of different patients.

[0021] In some possible implementations, the side plate 2 divides the bottom plate 1 to form a first part 11 and a second groove 12112. The first groove 111 is located in the first part 11, and the angle adjustment component 6 is disposed on the second groove 12112. A headrest 7 is fixedly disposed at the top middle position of the first part 11. The headrest 7 is located between the first groove 111 and the side plate 2, and a pair of arm support components 5 are symmetrically distributed on both sides of the headrest 7.

[0022] The headrest 7 has a groove in the middle where the patient's head can rest, thus restricting the patient's position. The top of the headrest 7 is sloping and has a certain height to accommodate patients who cannot lie completely flat, such as those with kyphosis or lung diseases.

[0023] In practical use, the fixed bracket of this application can be placed on the CT bed, the patient lies supine with the head in the groove of the headrest 7, and then the bidirectional drive component 4 is adjusted to adjust the arm support component 5 to a position corresponding to the patient's shoulder width and body shape. Then the patient extends the arm and places and fixes the arm on the arm support component 5. The angle adjustment component 6 can be adjusted to reduce or increase the tilt angle of the arm support component 5 to adapt to the physical needs of patients with frozen shoulder or hemiplegia after stroke, because some patients with frozen shoulder or hemiplegia after stroke have limited arm extension angle.

[0024] In some possible implementations, a pair of snap-fit ​​slots are symmetrically provided on both sides of the height adjustment area 21. The height adjustment component includes a sliding plate 31 and snap-fit ​​parts fixedly disposed on both sides of the sliding plate 31. One snap-fit ​​part is movably snapped into a corresponding snap-fit ​​slot. A transverse sliding groove 311 is provided on the sliding plate 31. The transverse sliding groove 311 is arranged perpendicularly to the snap-fit ​​slot.

[0025] Specifically, such as Figure 1-3 As shown, the height adjustment area 21 is a hollow area. The height adjustment component engages with the engagement slot via a snap-fit ​​part to confine the sliding plate 31 within the height adjustment area 21, allowing the sliding plate 31 to slide up and down only within this area. By providing a transverse groove 311 on the sliding plate 31, the arm support assembly 5 can move relative to the transverse groove 311 when driven to move by the bidirectional drive component 4.

[0026] In some possible implementations, the sidewall of the first part 11 has a first through hole communicating with the first groove 111. The bidirectional drive assembly 4 includes: a bidirectional lead screw 41, a first knob 42, and a pair of first sliders 43. One end of the bidirectional lead screw 41 passes through the first through hole and the first groove 111 in sequence and is rotatably connected to the sidewall of the groove. The first knob 42 is fixedly disposed at the other end of the bidirectional lead screw 41. The pair of first sliders 43 are threadedly connected to the bidirectional lead screw 41 and abut against the sidewall of the first groove 111. Rotating the first knob 42 drives the pair of first sliders 43 to move relative to or away from each other. An arm support assembly 5 is hinged to one of the first sliders 43.

[0027] Specifically, the bidirectional lead screw 41 is provided with a left-hand thread and a right-hand thread, and one first slider 43 is threadedly connected to the left-hand thread and the other first slider 43 is threadedly connected to the right-hand thread, so that when the rotating knob drives the bidirectional lead screw 41 to rotate, the two first sliders 43 can move closer to each other or further away from each other at the same time, which is convenient for width adjustment according to the patient's shoulder width or body shape.

[0028] In some possible implementations, each arm support assembly 5 includes: a joint support 51, an arm support 52, and a locking ball 53; one joint support 51 is hinged to a first slider 43, and one end of the arm support 52 is fixedly connected to the joint support 51; the locking ball 53 is connected to the other end of the arm support 52 via a hinge, the hinge passing through a transverse groove 311, and the outer diameter of the locking ball 53 is larger than the width of the transverse groove 311.

[0029] The arm support 52 has an arc-shaped groove to facilitate placing the arm in the groove. The arm support 52 is also equipped with a soft pad to improve the comfort of placement. The edges of the arm support 52 can be rounded to avoid injury to the patient's arm.

[0030] In some possible implementations, at least one pair of Velcro straps 521 are fixedly provided on each arm support 52, and two pairs of Velcro straps 521 can be provided at intervals to fix the patient's upper arm and forearm separately through the Velcro straps 521 to prevent the patient's arm from moving during the scanning process.

[0031] Furthermore, each joint support 51 has a flexible support area at its top, which can be a pressure-dispersing pad to avoid direct pressure on the patient's shoulder joint. This pressure-dispersing pad may contain a heat-dissipating pad to promote local blood circulation and relieve patient pain.

[0032] In some possible embodiments, the second groove 12112 of the base plate 1 is provided with a second groove, the arrangement direction of the second groove is perpendicular to the arrangement direction of the first groove 111, and a second through hole is provided on the side of the second groove 12112 away from the side plate 2, the second through hole being located in the arrangement direction of the second groove; the angle adjustment assembly 6 includes: a connecting rod 61, a screw 62, a second knob 63 and a second slider 64; one end of the connecting rod 61 is hinged to the side wall of the base plate 1; one end of the screw 62 passes through the second through hole and the second groove in sequence and is rotatably connected to the side wall of the second groove; the second knob 63 is fixedly connected to the other end of the screw 62; the second slider 64 is sleeved on the screw 62 and connected to the screw 62, the second slider 64 abuts against the side wall of the second groove, and the other end of the connecting rod 61 is hinged to the top of the second slider 64.

[0033] Specifically, by rotating the second knob 63, the screw 62 is driven to rotate, causing the second sliding connected to the screw 62 to move linearly, thereby causing the second sliding to move closer to or away from the side plate 2, and thus driving the side plate 2 to rotate.

[0034] This application has the following advantages: 1. Stable fixation, preventing the patient's arm from moving during scanning and reducing motion artifacts; 2. Compatible with patients of different body types (adults / children) and CT bed models; 3. Convenient operation, allowing medical staff to quickly adjust and easy disinfection and cleaning.
