[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example:

[0032] See also Figure 1-Figure 8 A leg support for radiotherapy comprises a metal leg 1, a support plate 101 is fixedly mounted on the top of the metal leg 1, a popliteal fossa support plate 102 is arranged on the top of the support plate 101, and the top of the popliteal fossa support plate 102 is arranged in an arc shape;

[0033] A rotating seat 2 is fixedly installed on the side of the support plate 101, and a rod group 21 is rotatably connected to the rotating seat 2. A rotating seat 22 is fixedly installed at the end of the rod group 21, and a leg support plate 23 is rotatably installed on the rotating seat 22. The surface of the leg support plate 23 and the popliteal fossa support plate 102 are both covered with a non-slip rubber sleeve 24 filled with sponge;

[0034] The rod group 21 includes an extension rod 211 fixedly connected to the outer side of the rotating seat 22 and a support sleeve 212 rotatably connected to the rotating seat 22. The extension rod 211 is slidably connected to the inner side of the support sleeve 212. The outside of the support sleeve 212 is provided with a first adjustment unit for limiting the relative sliding between the extension rod 211 and the support sleeve 212.

[0035] A second adjustment unit is provided between the rod group 21 and the rotating seat 2, and is used to limit the rotation between the rod group 21 and the rotating seat 2;

[0036] A third adjusting unit is provided between the leg support plate 23 and the rotating seat 22 , and is used to limit the rotation between the leg support plate 23 and the rotating seat 22 .

[0037] In this embodiment, the first adjustment unit includes a short column 3 fixedly installed at the end of the support sleeve 212. The surface of the short column 3 is provided with a thread groove 31 extending into the interior of the support sleeve 212. The inner side surface of the thread groove 31 is threadedly connected with a limiting screw 32, and the end of the limiting screw 32 is anti-slip.

[0038] During use, the limiting screw 32 is rotated to separate the limiting screw 32 from the surface of the extension rod 211, so that the movement of the extension rod 211 is no longer restricted, and the extension rod 211 and the support sleeve 212 are allowed to slide relative to each other, so that the extension rod 211 can drive the leg support plate 23 set at its top to adjust the position height. After the adjustment is completed, the limiting screw 32 is rotated in the opposite direction so that the end of the limiting screw 32 abuts against the surface of the extension rod 211, so that the movement of the extension rod 211 is restricted, thereby providing stable support for the leg support plate 23.

[0039] In this embodiment, the second adjustment unit includes a clamping wheel 4 coaxially fixedly connected to the supporting sleeve 212, the outer side surface of the clamping wheel 4 is in a circular ring shape and has a plurality of clamping grooves 41 equidistantly provided thereon, a sleeve box 42 is fixedly installed on the outside of the rotating seat 2, a limiting sleeve 43 is slidably connected to the inner side surface of the sleeve box 42, the inner side surface of the limiting sleeve 43 is in a circular ring shape and has a plurality of clamping strips 44 equidistantly provided thereon, a pressure spring 45 is fixedly connected between the limiting sleeve 43 and the inner wall of the sleeve box 42, a square rod 46 is fixedly connected to the surface of the limiting sleeve 43, and a limiting square groove 47 is provided on the surface of the sleeve box 42.

[0040] It should be added that the square rod 46 is slidably connected to the inner side surface of the limiting square groove 47, and the shape and size specifications of the square rod 46 are compatible with the limiting square groove 47, and the shape and size value of the clamping strip 44 are compatible with the clamping groove 41, so that the limiting square groove 47 can stably guide the square rod 46, and the square rod 46 can no longer restrict the rotation inside the square groove 47, thereby ensuring that when the limiting sleeve 43 is sleeved on the outside of the clamping wheel 4, the limiting sleeve 43 can stably limit the rotation of the clamping wheel 4.

[0041] During operation, the square rod 46 is pulled outward, so that the square rod 46 drives the limiting sleeve 43 to move and separate from the card wheel 4, and compresses the pressure spring 45. When the limiting sleeve 43 moves and separates from the card wheel 4, the card strip 44 withdraws from the card slot 41, so that the rotation of the card wheel 4 is no longer restricted. At this time, the operator can rotate the rod group 21 so that the leg support plate 23 on the top of the rod group 21 can rotate accordingly, so that the position height of the leg support plate 23 and the distance value between the popliteal fossa support plate 102 can be adjusted. When the adjustment is completed, the operator releases the square rod 46. Under the action of the rebound force of the pressure spring 45, the limiting sleeve 43 moves in the opposite direction and drives the card strip 44 to be clamped into the card slot 41 again, so that the rotation of the card wheel 4 can be restricted, so that the rod group 21 can stably support the leg support plate 23 set on its top.

[0042] In this embodiment, the third adjustment unit includes a rotating groove 5 opened inside the rotating seat 22, and the inner side surface of the rotating groove 5 is rotatably connected to a limiting wheel 51, and a support rod 52 is fixedly connected between the limiting wheel 51 and the leg support plate 23. The support rod 52 and the leg support plate 23 are vertically arranged, and a limiting rotating groove 53 connected to the rotating groove 5 is opened on the surface of the rotating seat 22. The limiting rotating groove 53 limits the rotation angle range of the support rod 52 to 0° to 180°, that is, the support rod 52 can be rotated upward from a horizontal state on one side to a horizontal state on the other side.

[0043] It should be supplemented that a receiving groove 54 is provided on the inner wall of the rotating groove 5, and an anti-slip plate 55 is slidably connected to the inner side surface of the receiving groove 54, and the surface of the anti-slip plate 55 is anti-slip, and a limiting strip 56 is fixedly connected to the surface of the anti-slip plate 55. The outer surface of the limiting wheel 51 is annular and has a plurality of limiting strip grooves 57 equidistantly provided thereon. The outside of the rotating seat 22 is fixedly connected to an internal threaded tube 58, and the inner side surface of the internal threaded tube 58 is threadedly connected to a locking screw 59.

[0044] In addition, the end of the locking screw 59 passes through the rotating seat 22 and is rotatably connected to the anti-slip plate 55, that is, a connecting groove connected to the accommodating groove 54 is opened on the surface of the rotating seat 22, and the locking screw 59 can pass through the connecting groove. The shape and size of the limiting strip groove 57 are compatible with the limiting strip plate 56.

[0045] During operation, by rotating the locking screw 59, the anti-slip plate 55 is moved and drives the limiting strip 56 to withdraw from the limiting strip groove 57, so that the rotation of the limiting wheel 51 is no longer restricted, so that it can rotate and drive the leg support plate 23 to rotate, thereby adjusting its inclination angle.

[0046] It should be further explained that during use, the leg support has two usage states:

[0047] The first state: the popliteal fossa supporting state, that is, when the knee needs to be fully exposed during treatment, only the popliteal fossa is supported. In this state, the leg support plate 23 is rotated to a vertical state by controlling the third adjusting unit, and then the rod group 21 is rotated to a vertical state by controlling the second adjusting unit. Finally, the extension rod 211 is moved toward the inside of the supporting sleeve 212 and retracted by controlling the first adjusting unit, so that the leg support plate 23 can be close to the supporting plate 101 and be in the lowest position, so that the popliteal fossa support plate 102 can work alone;

[0048] The second state: the calf support state, that is, when the leg or foot treatment is performed and the leg needs to be supported, the calf is supported as a whole. In this state, the inclination angle of the leg support 23 can be adjusted by controlling the third adjustment unit, and then the inclination angle of the rod group 21 and the top position height of the extension rod 211 can be adjusted synchronously through the cooperation of the first adjustment unit and the second adjustment unit, so that the leg support 23 can be moved to a position compatible with the popliteal fossa support 102, so that the two can cooperate to provide stable support for the patient's legs.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
