The hand support is movably connected to the fixed plate through a movable shaft, and both ends of the bottom of the fixed plate are respectively fixed on both sides of the window through bolts. Since the positions of the bolts are not adjustable, it is inconvenient to install the fixed plate on windows with different widths; although the fixed plate and the hand support can achieve the effect of an adjustable angle during support through the movable shaft, there is no limit after the movement is completed, and it is very easy to shake when the arm is placed on the hand support, thus causing certain potential safety hazards. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a hand support for interventional surgery, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

An activity shaft is provided at the ends of the fixing plate and the hand support close to each other. The ends of the fixing plate and the hand support close to each other are rotationally connected through the activity shaft. At both ends of the bottom of the fixing plate at the position of the activity shaft, screw rods II are fixed. Nut IIIs are threadedly connected to the outer walls of the screw rods II. T-shaped sliding grooves are respectively drilled at the ends of the bottom of the fixing plate far from nut II. Slide plates are slidably connected to the interiors of the T-shaped sliding grooves. Screw rods I are fixed to the bottoms of the slide plates at the central positions of the T-shaped sliding grooves. One ends of the screw rods I far from the T-shaped sliding grooves extend to the outer sides of the bottom of the fixing plate. Two nut Is are threadedly connected to the outer walls of the screw rods I at the outer ends of the fixing plate. A traction rod is provided at the bottom of the hand support. An arc-shaped block is fixed to one end of the traction rod close to the fixing plate. A plurality of internal teeth are provided on the side wall of the arc-shaped block close to the fixing plate. A plurality of external teeth are provided on the side wall of the fixing plate at the position of the internal teeth. A fixed sliding plate is fixed to one end of the bottom of the hand support close to the external teeth. A tension spring is fixed to the side of the fixed sliding plate far from the fixing plate. A fixed side plate is fixed to the outer wall of the traction rod at the end far from the fixed sliding plate. A handle rod is fixed to the end of the traction rod far from the fixed side plate.

[0007] Preferably, the top of the nut II is in contact with the bottom of the fixing plate.

[0010] Preferably, one end of the nut III far from the traction rod is located at the side wall position of the hand support, and the horizontal line at the top of the end of the nut III far from the traction rod is lower than the horizontal line at the top of the hand support.

[0011] Preferably, a fixed sliding cylinder is fixed to one end of the bottom of the hand support far from the fixed side plate. The traction rod is slidably connected after passing through the fixed sliding cylinder.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The bottom of the fixing plate is installed at one end of the hospital bed by using screw two and nut three, and the position of screw one can be changed by the sliding of the slider plate in the T-shaped chute at the other end. Thus, the fixing plate can be adjusted according to the width of the hospital bed after adaptation. After the adjustment is completed, the rotation of nut two can resist the position of the T-shaped chute at the bottom of the fixing plate, so that screw one remains unchanged at its current position at the bottom of the fixing plate. Then, screw one and nut one are used to limit the other end of the fixing plate at the end of the hospital bed far from screw two. The operation is simple, convenient and highly practical.

[0014] 2. The fixing plate and the handrest are rotatably connected by a movable shaft. After rotating through the movable shaft, it is convenient to adjust the angle of the supporting arm. After the adjustment is completed, the traction rod drives the inner teeth inside the arc-shaped block to engage with the outer teeth on the outer wall of the fixing plate by pulling the fixed side plate through the tension spring fixed on the side wall of the fixed sliding plate, thus completing the limiting effect of the adjusted angle. When adjustment is needed again, the doctor only needs to pull the handle rod away from the fixing plate, so that the inner teeth are away from the outer teeth, and then the handrest can change the angle between the movable shaft and the fixing plate. This way of limiting the angle after adjustment enables the doctor to provide better stability according to the requirements of supporting the arm during the interventional operation.

An activity shaft 3 is provided at the adjacent ends of the fixing plate 1 and the hand support 2. The adjacent ends of the fixing plate 1 and the hand support 2 are rotationally connected through the activity shaft 3. At both ends of the bottom of the fixing plate 1 at the position of the activity shaft 3, screw rods two 16 are fixed. Nut three 17 is threadedly connected to the outer wall of each screw rod two 16. At one end of the bottom of the fixing plate 1 away from nut two 15, T-shaped sliding grooves 11 are respectively drilled. Slide plates 12 are slidably connected inside the T-shaped sliding grooves 11. Screw rods one 13 are fixed to the bottoms of the slide plates 12 at the central positions of the T-shaped sliding grooves 11. One ends of the screw rods one 13 away from the T-shaped sliding grooves 11 extend to the outside of the bottom of the fixing plate 1. Two nut one 14 are threadedly connected to the outer walls of the screw rods one 13 at the outer ends of the fixing plate 1. A traction rod 21 is provided at the bottom of the hand support 2. An arc-shaped block 22 is fixed to one end of the traction rod 21 close to the fixing plate 1. A number of internal teeth 23 are provided on the side wall of the arc-shaped block 22 close to the fixing plate 1. A number of external teeth 18 are provided on the side wall of the fixing plate 1 at the position of the internal teeth 23. A fixed sliding plate 24 is fixed to one end of the bottom of the hand support 2 close to the external teeth 18. A tension spring 26 is fixed to the side of the fixed sliding plate 24 away from the fixing plate 1. A fixed side plate 25 is fixed to the outer wall of the traction rod 21 at the end of the fixed sliding plate 24 away from the fixing plate 1. A handle rod 27 is fixed to the end of the traction rod 21 away from the fixed side plate 25.

[0024] Specifically, the top of the nut two 15 is in contact with the bottom of the fixing plate 1.

[0025] Specifically, the traction rod 21 is in through communication with the tension spring 26 and the fixed sliding plate 24. After the traction rod 21 passes through the fixed sliding plate 24, they are slidably connected. One end of the tension spring 26 away from the fixed sliding plate 24 is fixedly connected to the side close to the fixed side plate 25.

[0026] Specifically, the internal teeth 23 are respectively meshed and connected with the externally matching external teeth 18 for limiting the adjusted angles of the fixing plate 1 and the hand support 2.

[0027] Specifically, the end of the nut three 17 away from the traction rod 21 is located at the side wall position of the hand support 2. The horizontal line at the top of the end of the nut three 17 away from the traction rod 21 is lower than the horizontal line at the top of the hand support 2, so as to avoid the height being too high and affecting the movement of the doctor's arm.

[0028] Specifically, a fixed sliding cylinder 28 is fixed at the bottom of the handrest 2 at one end away from the fixed sliding plate 24 of the fixed side plate 25. The traction rod 21 is slidably connected through the fixed sliding cylinder 28, making the sliding of the traction rod 21 more stable.

[0029] Working principle: The bottom of the fixing plate 1 is installed at one end of the hospital bed by using the second screw 16 and the third nut 17. The other end can change the positioning position of the first screw 13 by the sliding of the slider plate 12 in the T-shaped chute 11, so that the fixing plate 1 can be adjusted after being adapted according to the width of the hospital bed. After the adjustment is completed, the rotation of the second nut 15 can abut against the position of the T-shaped chute 11 at the bottom of the fixing plate 1, so that the first screw 13 remains unchanged at the current position at the bottom of the fixing plate 1. The first screw 13 is used in combination with the first nut 14 to limit the other end of the fixing plate 1 to the end of the hospital bed away from the second screw 16. The operation is simple, convenient and highly practical. The fixing plate 1 and the handrest 2 are rotatably connected by the movable shaft 3. After rotating through the movable shaft 3, it is convenient to adjust the angle of the supporting arm. After the adjustment is completed, the traction rod 21 drives the internal teeth 23 inside the arc-shaped block 22 to mesh with the external teeth 18 on the outer wall of the fixing plate 1 by pulling the fixed side plate 25 by the tension spring 26 fixed on the side wall of the fixed sliding plate 24, thus completing the limiting effect of the adjusted angle. When adjustment is needed again, the doctor only needs to pull the handle rod 27 away from the fixing plate 1, so that the internal teeth 23 are away from the external teeth 18, and then the handrest 2 can change the angle with the fixing plate 1 through the movable shaft 3. This way of limiting the angle after adjustment enables the doctor to provide better stability according to the requirements of the arm support for the interventional operation.
