[0080] As shown in Figures 1-2And Figure 11 As shown in the figure, the suspension unit 4 comprises a control side support 401 and a linkage side support 402, which are symmetrical to the center line of the bed body 3 and are installed on the top of the bed body 3, and an adjusting groove 404 is formed in the inside of the control side support 401 and the linkage side support 402.

[0081] The adjusting groove 404 is arranged on the top of the upper bed plate 301 and a hanging groove 4041 is formed in the inside thereof, a placing roller 405 is installed in the inside of the hanging groove 4041, and the control side support 401 and the linkage side support 402 are fixedly connected through a middle connecting frame 403, so that the placing roller 405 can be adjusted in position in the inside of the hanging groove 4041.

[0082] As shown in the figure, Figures 1-2 And Figures 9-10 As shown in the figure, a clamping groove 4051 is formed on the left and right sides of the placing roller 405, a sling 4052 is sleeved in the inside of the clamping groove 4051, and a hanging basket 406 for placing an infusion bottle is installed in the inside of the sling 4052.

[0086] By placing the injured leg of the fracture patient on the lifting belt 4074, when the patient needs to change their lying position, the handle 2022 can be turned counterclockwise. Alternatively, an external servo motor can be used to control the rotation of the rotating disk 202, causing the handle 2022 to drive the rotating disk 202 and the rotating shaft 203 to rotate synchronously. This causes the transmission component 2031 connected to the rotating shaft 203 to drive the lower toothed plate 2051 and the upper toothed plate 2041 to move in opposite linear directions. When the lower toothed plate 2051 moves away from the base plate 306, the upper bed board 301 is lifted by the rocker arm 207, thereby adjusting the patient's lying position to suit various needs after surgery. After adjustment, the rotating rod 20221 can be rotated to insert into the positioning hole 2011, thereby fixing the adjusted position.

[0087] When the rotating shaft 203 rotates counterclockwise, the primary winding wheel 208 on the rotating shaft 203 rotates synchronously, thereby releasing the forward moving rope 2082 on one side of the vertical frame 4071. Furthermore, with the cooperation of the lifting wheel 206, the linkage 2061, and the linkage wheel 2062, the rotating shaft 203 also causes the linkage wheel 2062 to drive the linkage shaft 20621 to rotate, synchronously controlling the secondary winding wheel 209 to rotate and release the rope. This releases the constraint on the lifting belt 4074, allowing the lifting belt 4074 to slowly descend when the upper bed board 301 is raised. This reduces the secondary injury to the fractured leg when changing the lying position; the secondary winding wheel 209 will drive the primary winding wheel 208 connected to it to reverse through the reversing rod 2084, thereby winding up the forward moving rope 2082 on the other side of the vertical frame 4071, driving the lifting belt 4074 to move laterally along the adjustment groove 404 of the suspension unit 4, thereby maintaining the lifting belt 4074 to stably lift the fracture site, preventing the lifting belt 4074 from moving forward due to the lifting of the upper bed board 301, which would cause the leg fixation position to shift and result in constriction injury at the fracture site.

[0088] When the patient needs to eat or perform other tasks, the base plate 306 can be pulled upwards to engage the locking plate 30632 on the side of the base plate 306 with the sleeve 305, and the placement plate 304 can be placed on the base plates 306 on both sides. After the patient has adjusted to a complete lying position, the placement plate 304 can be used in conjunction with the lifting strap 4074 to lower the fractured leg, making it convenient to meet the various needs of the patient after surgery and reducing secondary injuries after fracture surgery.
