The fixed cylinder is horizontally connected to the fixed plate. The ratchet tooth is slidably arranged inside the fixed cylinder and meshes with the ratchet wheel. The ratchet wheel is located on one side of the fixed cylinder and connected to a through hole preset on the guide plate. The second spring is arranged inside the fixed cylinder and horizontally arranged on one side of the ratchet tooth. When the patient needs to transfer to another bed, the arm bracket can be rotated downward by using the fixed cylinder. After rotating it under the operating bed, the ratchet tooth can be used to block the arm bracket to prevent the arm bracket from hindering the patient's transfer to another bed.

[0014] The beneficial effects of the present utility model compared with the prior art are:

[0015] When the patient transfers to another bed, the present utility model can use the rotating assembly to rotate and store the arm bracket under the operating bed to prevent the arm bracket from hindering the patient during the transfer.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be described in detail in conjunction with the accompanying Figures 1-13 drawings in the embodiments of the present invention.

[0031] As Figures 1-3 shown, an adjustable hand inserting plate device for radial artery intervention surgery includes an operating table 1 and a mattress 2, and further includes a fixing plate 3, a rotating assembly 4, a lifting assembly 5, a lifting component 6 and an arm support 7. The mattress 2 is placed on the operating table 1. The fixing plate 3 is located on one side of the mattress 2 and is inserted and connected at the position between the mattress 2 and the operating table 1. Therefore, after inserting the fixing plate 3 under the mattress 2 and waiting for the patient to lie on the mattress 2, the fixation can be completed.

[0032] As Figures 1-3 shown, the rotating assembly 4 is located on one side of the fixing plate 3 and is fixedly connected to the fixing plate 3. The lifting assembly 5 is connected to one end of the fixing plate 3 and is connected to the fixing plate 3 through the rotating assembly 4. Therefore, when the arm support 7 needs to be used, the arm support 7 can be opened downward with the rotating assembly 4 as the center and then fixed through the rotating assembly 4. At this time, after the arm support 7 is at the same height as the mattress 2, the patient can place the arm on the arm support 7.

[0033] As Figures 1-3 shown, and when the patient needs to transfer beds or needs to undergo X-ray irradiation, the rotating assembly 4 can be rotated downward until the arm support 7 moves under the operating table 1, and then the rotation can be stopped and the arm support 7 can be clamped by the rotating assembly 4 to avoid the arm support 7 from hindering the patient's bed transfer. One end of the lifting component 6 is connected above the lifting assembly 5.

[0034] As Figures 1-3As shown in the figure, after the arm support 7 is opened, the height of the arm support 7 can be adjusted downward by using the lifting component 5 according to the patient's body position, so that the patient can fully place the arm on the arm support 7 even in different body positions. The arm support 7 is located above the lifting component 6 and connected to the lifting component 5. When the patient lies on the operating table 1 and the height of the arm support 7 is insufficient, the height of the arm support 7 can be adjusted upward by using the lifting component 6.

[0035] As Figure 4 shown in the figure, the arm support 7 includes an arm support plate 71, a first arm support block 72, a second arm support block 73, and a damping slide rail 74. The arm support plate 71 is connected above the lifting plate 6 of the lifting component 63, so the lifting component 6 can adjust the height of the arm support plate 71 upward according to the use needs. The first arm support block 72 is connected above the arm support plate 71 by screws. The second arm support block 73 is located at one end of the first arm support block 72, and a chute is provided at the position of the second arm support block 73 on the arm support plate 71.

[0036] As Figure 4 shown in the figure, the second arm support block 73 is slidably arranged inside the chute. There are two groups of damping slide rails 74, and they are respectively connected to both sides of the second arm support block 73 by screws, and the second arm support block 73 is connected to the arm support plate 71 through the damping slide rails 74. Therefore, after the arm support 7 is opened, the second arm support block 73 can be pulled outwards according to the length of the patient's arm to extend the distance between the first arm support block 72 and the second arm support block 73, so as to ensure that the patient's arm can be fully placed on the first arm support block 72 and the second arm support block 73.

[0037] As Figure 4 shown in the figure, the lifting component 6 includes a fixed seat 61, a scissors arm 62, a lifting plate 63, a rotary damper 64, and a locking component 8. The rotary damper 64 is located at one end of the fixed seat 61, and the rotary damper 64 is connected to the rotary plate 56 of the lifting component 5 by screws. The fixed seat 61 is connected to the output end of the rotary damper 64. Therefore, the fixed seat 61 can rotate around the rotary damper 64 to adjust the angle between the arm support 7 and the operating table 1. There are two groups of scissors arms 62, which are both arranged inside the fixed seat 61 and located on both sides of the fixed seat 61 respectively.

[0038] As Figure 4 shown in the figure, the lifting plate 63 is arranged above the scissors arm 62. The locking component 8 is slidably arranged horizontally inside the fixed seat 61. The upper fixed shaft and the lower fixed shaft at one end of the two groups of scissors arms 62 are respectively hinged to the lifting plate 63 and the fixed seat 61. The upper fixed shaft at the other end of the two groups of scissors arms 62 is slidably connected to the preset chute of the lifting plate 63, and the lower fixed shafts at the other end of the two groups of scissors arms 62 are both connected to the sliding block 52 of the locking component 8.

[0039] like Figures 5-7 As shown, the lifting assembly 5 includes a guide plate 51, a sliding block 52, a clamping block 53, a brake screw 54, a first spring 55 and a rotating plate 56. The guide plate 51 is connected to the fixed plate 3 through the rotating assembly 4, so that the guide plate 51 can rotate and be fixed with the rotating assembly 4 as the center. The sliding block 52 is horizontally slidably set on the guide plate 51. There are two groups of clamping blocks 53, both of which are slidably set inside the sliding block 52, and the two groups of clamping blocks 53 are respectively set at both ends of the sliding block 52.

[0040] like Figures 5-7 As shown, one end of the two groups of clamping blocks 53 are arranged inside the sliding block 52, and the other ends of the two groups of clamping blocks 53 are arranged on the outside of the sliding block 52. The ends of the two groups of clamping blocks 53 located inside the sliding block 52 are each provided with a blind hole. There are two groups of first springs 55, and the two groups of first springs 55 are respectively arranged inside the blind holes of the two groups of clamping blocks 53. The two groups of first springs 55 are located on the outside of the two groups of clamping blocks 53, and the two ends of the two groups of first springs 55 are respectively clamped with the clamping block 53 and the sliding block 52.

[0041] like Figures 5-7 As shown, when the card block 53 is pressed, the card block 53 will squeeze the first spring 55 while moving inside the phase sliding block 52. At this time, the sliding block 52 can slide on the guide plate 51. After the sliding block 52 moves to the desired position, the card block 53 can be released, and the first spring 55 will pop out the card block 53 at this time, so that it is stuck in the preset card slot on the guide plate 51 to fix the position of the sliding block 52 to prevent it from continuing to slide.

[0042] like Figures 5-7 As shown, the brake screw 54 is located on one side of the sliding block 52 and is threadedly connected to the sliding block 52. The rotating plate 56 is located on one side of the clamping block 53 and is hinged to the sliding block 52. One end of the brake rod passes through the sliding block 52 and contacts the rotating plate 56. Therefore, after the rotating plate 56 has completed its rotation, the brake rod can be rotated to resist the rotating plate 56 to prevent the rotating plate 56 from continuing to rotate. The rotation damper 64 is connected to the rotating plate 56 by screws. Therefore, when the rotating plate 56 rotates, the rotation damper 64 will be driven to rotate together.

[0043] like Figures 8-10 As shown, the locking assembly 8 includes a guide block 81, a moving block 82, a stop block 83, a pressure rod 84, a fixed shell 85, a sliding shell 86, a third spring 87 and a fourth spring 88. The guide block 81 has two groups, both of which are connected to the inside of the fixed seat 61 by screws. The two groups of scissor arms 62 are located on the outside of the guide block 81. The moving block 82 is arranged to slide horizontally in the middle of the two groups of guide blocks 81. The two groups of scissor walls are hinged to the sliding block 52. The fixed shell 85 is located at one end of the moving block 82 and is arranged inside the preset groove of the moving block 82.

[0044] As shown Figures 8-10 in the figure, the sliding shell 86 is slidably arranged inside the fixed shell 85. The pressing rod 84 is located on one side of the sliding shell 86 and connected to the sliding shell 86. Therefore, when the pressing rod 84 is pressed, the pressing rod 84 will drive the sliding shell 86 and the stopper 83 to slide inside the fixed shell 85. The stopper 83 is slidably arranged inside the sliding shell 86 and clamped on the sliding shell 86. A tooth groove corresponding to the stopper 83 is formed on the guide block 81 on one side of the stopper 83. The third spring 87 is arranged inside the sliding shell 86 and located at one end of the stopper 83. Both ends of the third spring 87 are clamped with the sliding shell 86 and the stopper 83 respectively.

[0045] As shown Figures 8-10 in the figure, therefore, when the arm support block is lifted upward, the sliding block 52 and the stopper 83 will slide forward under the drive of the scissors arm 62. At this time, the stopper 83 will reciprocate inside the sliding shell 86 under the resistance of the guide block 81. When the sliding block 52 stops sliding, the stopper 83 will be clamped into the tooth groove of the guide block 81 under the action of the third spring 87, and the permanent magnet will lock the position of the sliding block 52. At this time, the sliding block 52 can fix the height of the arm bracket 7 through the scissors arm 62 to prevent it from falling suddenly.

[0046] As shown Figures 8-10 in the figure, the fourth spring 88 is arranged inside the fixed shell 85 and located at one end of the pressing rod 84. Both ends of the fourth spring 88 are clamped with the pressing rod 84 and the fixed shell 85 respectively. When it is necessary to lower the height of the arm bracket 7, the pressing rod 84 can be pressed inward. When the pressing rod 84 moves inside the fixed shell 85, it will synchronously drive the sliding shell 86 and the stopper 83 inside the sliding shell 86 to move inside the fixed shell 85. Until the stopper 83 disengages from the tooth groove of the guide block 81, the arm support block can be pressed downward. After the lifting plate 63 is in full contact with the fixed seat 61, the pressing rod 84 can be released.

[0047] As shown Figures 11-13 in the figure, the rotating assembly 4 includes a fixed cylinder 41, a ratchet tooth 42, a second spring 43 and a ratchet wheel 44. The fixed cylinder 41 is transversely welded on the guide plate 51. The ratchet tooth 42 is slidably arranged inside the fixed cylinder 41. There is a slotted opening at the top of the fixed cylinder 41. The top of the ratchet tooth 42 passes through the fixed cylinder 41 and is arranged outside the fixed cylinder 41 and clamped inside the ratchet wheel 44. The ratchet wheel 44 is located on one side of the fixed cylinder 41 and welded in a preset through hole of the guide plate 51, and the ratchet wheel 44 is sleeved on the fixed cylinder 41.

[0048] As shown Figures 11-13As shown, the second spring 43 is arranged inside the fixed cylinder 41 and on one side of the ratchet 42. Therefore, when the guide plate 51 needs to be rotated, the ratchet 42 can be pressed inward. At this time, the ratchet 42 will start to squeeze the second spring 43 to deform and store energy. After squeezing the ratchet 42 out of the inside of the ratchet wheel 44, the guide plate 51 can be rotated. After the guide plate 51 is rotated, the ratchet 42 can be released. At this time, the second spring 43 will eject the ratchet 42 to make it re-insert into the inside of the ratchet wheel 44 for fixation.

[0049] The movement process of this embodiment: After the patient lies on the mattress 2, the fixing plate 3 can be inserted under the mattress 2 for fixation. Then, the pressing rod 84 can be pressed. After the ratchet 42 disengages from the inside of the ratchet wheel 44, the arm bracket 7 is rotated downward to open until the arm bracket 7 is parallel to the operating table 1. Then, the brake screw 54 is rotated forward to open. Then, the arm bracket 7 is rotated upward until the arm bracket 7 is parallel to the mattress 2, and then the brake screw 54 is rotated in the reverse direction to fix the position of the arm bracket 7.

[0050] Then, according to the position of the patient's arm, the arm bracket 7 can be rotated around the rotary damper 64 to abduct or adduct the arm bracket 7 to change the angle between the arm bracket 7 and the operating table 1. Subsequently, according to the patient's body position, the height of the arm bracket 7 can be adjusted. When the height of the arm bracket 7 needs to be adjusted downward, the two sets of clamping blocks 53 are pressed inward, and then the sliding block 52 is moved downward. After the height of the arm bracket 7 drops to the required height, the clamping blocks 53 can be released.

[0051] When the height of the arm bracket 7 needs to be adjusted upward, after the arm bracket 7 is rotated and opened, the arm bracket 7 can be lifted upward to adjust it to the required height. Then, according to the length of the patient's arm, the second arm support block 73 is pulled outward to extend the length between the first arm support block 72 and the second arm support block 73. Then, the patient's arm can be placed on the arm bracket 7.

[0052] When the patient needs to transfer beds, the arm bracket 7 is rotated until the angle between the arm bracket 7 and the mattress 2 is a right angle. Then, the brake screw 54 is rotated forward. Then, the arm bracket 7 is rotated downward until the arm bracket 7 is parallel to the guide plate 51. Then, the brake screw 54 is rotated in the reverse direction. Then, the ratchet 42 is pressed and the arm bracket 7 is rotated clockwise until the arm bracket 7 rotates under the operating table 1, and then the ratchet 42 can be released.

[0053] The above embodiments are only used to illustrate the technical idea of the present invention and cannot limit the protection scope of the present invention. Any changes made on the basis of the technical solution according to the technical idea proposed by the present invention fall within the protection scope of the present invention.
