[0041] like Figures 1 to 3 as well as Figure 5 As shown, in this embodiment, the leg support device includes: a base 10, a mounting portion 20, a mounting frame 30, a sliding member 40, a mounting seat 50, a rotating member 61, a driving member 62 and a foot support member 63. The mounting portion 20 is arranged on the base 10, and a plurality of positioning recesses 21 are arranged at intervals on the side wall of the mounting portion 20. The mounting frame 30 is slidably arranged on the mounting portion 20, and the mounting frame 30 includes a main body 31, a first connecting arm 32 and a limiting plate 33. The first connecting arm 32 and the limiting plate 33 are both connected to the main body 31, and the first connecting arm 32 and the limiting plate 33 are arranged at intervals in the vertical direction. The limiting plate 33 is located above the mounting portion 20, and the first connecting arm 32 is located on the side wall of the mounting portion 20. The first connecting arm 32 is provided with a first protrusion 321 that matches any one of the plurality of positioning recesses 21. The sliding member 40 includes a handle portion 41, a second connecting arm 42 and a stopper 43. The second connecting arm 42 and the stopper 43 are both connected to the handle portion 41. The stopper 43 is arranged below the handle portion 41. The second connecting arm 42 can cooperate with the limiting plate 33. The sliding member 40 has a locking position and an unlocking position. When the sliding member 40 is in the unlocking position, the stopper 43 avoids the first protrusion 321. When the sliding member 40 is in the locking position, the stopper 43 cooperates with the first protrusion 321. The mounting seat 50 is mounted on the mounting frame 30. The top of the mounting seat 50 is provided with a mounting recess 51. The rotating member 61 is rotatably arranged in the mounting recess 51. The driving member 62 cooperates with the rotating member 61 to drive the rotating member 61 to rotate. The foot support member 63 is connected to the rotating member 61.

[0042] The technical solution of this embodiment is applied, the mounting portion 20 is arranged on the base 10, and the side wall of the mounting portion 20 is provided with a positioning recess 21 at intervals. The mounting frame 30 is slidably arranged on the mounting portion 20, and the mounting frame 30 includes a main body 31, a first connecting arm 32 and a limiting plate 33, the first connecting arm 32 and the limiting plate 33 are arranged at intervals along the vertical direction and are both connected to the main body 31. The first connecting arm 32 is provided with a first protrusion 321. The sliding member 40 includes a handle portion 41, a second connecting arm 42 and a stopper 43, the second connecting arm 42 and the stopper 43 are both connected to the handle portion 41, and the stopper 43 is arranged below the handle portion 41. The second connecting arm 42 can be limited and matched with the limiting plate 33. The sliding member 40 has a locking position and an unlocking position. When the sliding member 40 is in the unlocking position, the stopper 43 avoids the first protrusion 321. When the sliding member 40 is in the locking position, the stopper 43 cooperates with the first protrusion 321. The mounting seat 50 is arranged on the mounting frame 30, and a mounting recess 51 is arranged on the top of the mounting seat 50. The rotating member 61 is rotatably arranged in the mounting recess 51, the driving member 62 cooperates with the driving of the rotating member 61, and the foot support member 63 is connected to the rotating member 61. Through the above-mentioned arrangement, the foot support member 63 can support the patient's foot, thereby making the position of the foot more stable. The rotating member 61 can realize rotation and then drive the foot support member 63 to rotate, thereby realizing the position adjustment of the patient's foot. The mounting recess 51 can limit the position of the rotating member 61 and make the position of the rotating member 61 more stable. The mounting frame 30 is slidably arranged on the mounting portion 20, that is, when the position of the foot support member 63 needs to be adjusted, the medical staff operates the handle portion 41, so that the stopper 43 avoids the first protrusion 321, and the first protrusion 321 is separated from the positioning recess 21, so that the mounting frame 30 can slide. When the position is determined, the sliding member 40 is driven, so that the stopper 43 limits the first protrusion 321, thereby preventing the first protrusion 321 from separating from the positioning recess 21, thereby ensuring the stability of the position of the mounting frame 30. At the same time, since the second connecting arm 42 can cooperate with the limiting plate 33, the position of the sliding member 40 can be ensured, and the sliding member 40 can be prevented from moving due to misoperation. And unlocking and locking by pushing and pulling makes it easier to adjust the position of the mounting frame 30. Therefore, the technical solution of this embodiment effectively solves the problem that the position adjustment operation of the leg support device in the related art is difficult.

[0043] Specifically, a positioning pin is provided on the side wall of the main body 31, and the positioning pin is connected to the mounting seat 50. The mounting seat 50 and the main body 31 are fixedly connected by the positioning pin, and the first protrusion 321 can be embedded in the positioning recess 21. At this time, the mounting seat 50 is moved back and forth. Since the first connecting arms 32 on both sides of the main body 31 are longer and thus subjected to outward tension, the first protrusion 321 at the end of the first connecting arm 32 makes an ups and downs motion in multiple positioning recesses 21.

[0044] If the sliding member 40 is moved away from the mounting frame 30, the second protrusion 421 on the second connecting arm 42 of the sliding member 40 moves along the inclined surfaces on both sides of the limiting plate 33. As the slope rises, the tension increases, and the pulling force fed back to the hands of the medical staff also increases (they can feel the force feedback). Finally, after passing the highest point, the tension decreases, and the second protrusion 421 is blocked by the stop surface 333. At this position, the stop 43 can limit the position of the first connecting arm 32, and the sliding member 40 is in a locked position.

[0045] To unlock, a certain force is required to push the sliding member 40 forward so that the first protrusion 321 passes over the stop surface 333 .

[0046] like Figures 6 to 8 as well as Figures 10 to 12 As shown, in this embodiment, the limit plate 33 includes a first plate body 331 and a second plate body 332, the first plate body 331 is connected between the second plate body 332 and the main body 31, the width of the first plate body 331 gradually increases in the direction from the first plate body 331 to the second plate body 332, and a stop surface 333 is provided between the first plate body 331 and the second plate body 332. The setting of the stop surface 333 can stop the second connecting arm 42, so that the sliding member 40 can be kept in the locked position. And because the shape of the first plate body 331 is conical, the movement of the second connecting arm 42 can be guided.

[0047] like Figure 6 , Figure 7 as well as Figures 10 to 12 As shown, in this embodiment, the width of the second plate 332 gradually decreases from the first plate 331 to the second plate 332. The second plate 332 is also tapered, and the maximum width of the first plate 331 is greater than the maximum width of the second plate 332, that is, when the sliding member 40 is in the locked position, the second connecting arm 42 can move away from the first plate 331 under the action of the side wall of the second plate 332, thereby preventing the sliding member 40 from crossing the stop surface 333.

[0048] like Figure 6 , Figure 7 as well as Figures 10 to 12As shown, in this embodiment, a second protrusion 421 is provided on the inner side of the second connecting arm 42, and the second protrusion 421 cooperates with the side wall of the limiting plate 33. When the sliding member 40 is in the locked position, the second protrusion 421 cooperates with the stop surface 333. The second protrusion 421 can contact and cooperate with the side wall of the limiting plate 33, and the second protrusion 421 can also be stopped and cooperated by the stop surface 333. Specifically, the second protrusion 421 is semicircular, which can avoid the situation of being stuck during the movement of the sliding member 40.

[0049] like Figure 6 , Figure 7 as well as Figures 10 to 12 As shown, in this embodiment, there are two first connecting arms 32, which are spaced apart on both sides of the limiting plate 33, and there are two second connecting arms 42, which are spaced apart on both sides of the limiting plate 33. The above arrangement can achieve positioning, that is, the relative position of the mounting frame 30 and the sliding member 40 can be made more stable.

[0050] like Figures 1 to 5 as well as Figures 7 to 9 As shown, in this embodiment, the rotating member 61 includes a ball gear 611, and the driving member 62 includes a driving rod 621 and a driving wheel 622 disposed on the driving rod 621. The driving wheel 622 is provided with a tooth groove 6221 meshing with the ball gear 611. The setting of the ball gear 611 can achieve universal rotation, and the driving wheel 622 can cooperate with the ball gear 611, thereby driving the ball gear 611 to rotate, thereby driving the foot support member 63 to swing. Specifically, the driving wheel 622 can rotate and move.

[0051] The ball gear 611 and the driving wheel 622 can achieve relatively stable rotation in the sagittal plane under the meshing action between the gears without loosening, and at the same time limit the unnecessary adjustment of the foot support 63 in other directions, so that the leg can bend in a fixed sagittal plane, providing positioning stability and accuracy.

[0052] like Fig. 9 As shown, the driving wheel 622 has a first plane and a second plane, and the first plane and the second plane are arranged relative to each other, which can reduce the space occupied and make driving easier.

[0053] like Figures 1 to 5 , Figure 7 as well as Fig. 9 As shown, in this embodiment, the driving rod 621 is movably arranged along a direction perpendicular to the mounting frame 30 to the sliding member 40, and the driving wheel 622 moves synchronously with the driving rod 621.

The positioning pin 80 can be inserted into the patient's leg, thereby effectively achieving positioning.

[0055] like Fig.15 As shown, in this embodiment, the leg support device also includes a mounting structure, and the mounting structure is arranged between the positioning pin 80 and the base frame 70. Specifically, the mounting structure includes a column, a first fastener, a second fastener and a first clamping plate, the positioning pin is arranged between the first end of the column and the first clamping plate, the first fastener is arranged at the second end, and the second fastener is connected between the first clamping plate and the column.
