DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0012] The present invention discloses an adjustable postoperative leg support fixing device, referring to Figures 1 to 6The device mainly consists of a thigh component 1, a calf component 2, a foot component 3, a first connecting rod 4 and a second connecting rod 5. One end of the first connecting rod 4 is connected to the thigh component 1 by a rotational connection, and the other end is connected to the calf component 2 by a rotational connection, thereby realizing a flexible connection between the thigh component 1 and the calf component 2. At the same time, one end of the second connecting rod 5 is connected to the calf component 2 by a rotational connection, and the other end is connected to the foot component 3 by a rotational connection. This design enables the calf component 2 and the foot component 3 to also achieve flexible connection and angle adjustment.

[0013] Further, the thigh component 1 is composed of a first support plate 101, a first airbag 102 and a first locking knob 103. The first airbag 102 is fixedly arranged at the upper end of the first support plate 101, and can be fitted and fixed to the thigh part of the patient by inflation. The first locking knob 103 is threadedly connected to both sides of the first support plate 101, and is used to lock and fix the position of the first connecting rod 4 to ensure the stability of the connection between the thigh component 1 and the calf component 2. In addition, the inner side of the first support plate 101 is also specially designed with a hollow structure, which can not only reduce the weight of the device, but also increase ventilation and improve the comfort of the patient when using it. The first airbag 102 is also fixedly provided with a first air inlet 104, which is convenient for the user to inflate or deflate the airbag as needed to adjust the inflation amount of the airbag, thereby achieving adaptive fitting to the thigh part. The top of the first airbag 102 is also fixedly provided with a first strap 105, which is used to further fix the patient's thigh to ensure that it will not shift during use.

[0014] The calf assembly 2 includes a second support plate 201, a second airbag 202 and a second locking knob 203. The second airbag 202 is also fixedly arranged at the upper end of the second support plate 201, and can be fitted and fixed to the patient's calf by inflation. The second locking knob 203 is threadedly connected to both sides of the second support plate 201, and is used to lock and fix the position of the second connecting rod 5 to ensure the stable connection between the calf assembly 2 and the foot assembly 3. The inner side of the second support plate 201 is also designed with a hollow structure, which echoes the design of the thigh assembly 1, further reduces the weight of the device and increases ventilation. The second airbag 202 is fixedly provided with a second air inlet 204, which is convenient for the user to inflate or deflate the airbag as needed to adjust the inflation amount of the airbag, thereby achieving adaptive fitting to the calf. The top of the second airbag 202 is also fixedly provided with a second strap 205, which is used to further fix the patient's calf to ensure that it will not shift during use.

[0015] The foot component 3 includes a foot support plate 301, a heel pad 302, an ankle pad 303, a foot strap 304 and a third locking knob 305. The heel pad 302 is fixedly arranged at the inner end of the foot support plate 301, and the ankle pad 303 is fixedly arranged on both sides of the foot support plate 301. The design of the pad can effectively reduce the pressure and friction of the device on the easily worn and injured position of the patient's foot, and play a good protective role. The foot strap 304 is fixedly arranged on both sides of the foot support plate 301 to fix the patient's foot and ensure that it remains stable during use. The third locking knob 305 is threadedly connected to both sides of the foot support plate 301 to lock and fix the position of the second connecting rod 5 to ensure the stable connection between the foot component 3 and the calf component 2.

[0016] In addition, the device of the present invention is specially designed with adjustable lengths of the first connecting rod 4 and the second connecting rod 5. This design enables the device to be flexibly adjusted according to the actual length of the patient's legs, while also meeting the patient's needs for changes in leg support angle and height during the recovery phase, thereby providing a more personalized support solution for the patient.

[0017] The working principle and use process of this device are as follows: During use, the device must first be preliminarily adjusted according to the specific conditions of the patient's legs. The medical staff will place the patient's thigh on the first support plate 101 of the thigh assembly 1, and inflate the first airbag 102 through the first air inlet 104 so that the airbag can fit closely to the patient's thigh, thereby achieving preliminary fixation. At this time, the inflation amount of the first airbag 102 can be flexibly adjusted according to the thickness and shape of the patient's thigh to ensure that the airbag is neither too tight to cause compression discomfort nor too loose to provide stable support. After inflation is completed, the medical staff will wrap the first strap 105 around the patient's thigh and tighten it to further enhance the firmness of the fixation and prevent unnecessary movement of the patient's legs during the rehabilitation process.

[0018] At the same time, the medical staff will place the patient's calf on the second support plate 201 of the calf assembly 2, and inflate the second airbag 202 through the second air inlet 204 to fit the patient's calf. Similar to the adjustment method of the first airbag 102, the inflation amount of the second airbag 202 can also be accurately adjusted according to the size of the patient's calf to achieve the best fixation effect. After the inflation is completed, the medical staff will wrap the second strap 205 around the patient's calf and tighten it to ensure stable fixation of the calf.

[0019] For the foot component 3, the medical staff will place the patient's foot on the foot support plate 301. At this time, the heel pad 302 and the ankle pad 303 can provide additional protection for the patient's foot and reduce the pressure of the device on the easily worn and injured parts of the foot. Afterwards, the medical staff will wrap the foot strap 304 around the patient's foot and tighten it to further fix the patient's foot and ensure that it remains stable during use.

[0020] After completing the above fixation operation, the medical staff will adjust the length of the first connecting rod 4 and the second connecting rod 5 according to the length of the patient's leg and the needs of the rehabilitation stage. By adjusting the length of the connecting rod, the relative positions between the thigh component 1, the calf component 2 and the foot component 3 can be changed, thereby achieving adaptive adjustment of the patient's leg length. At the same time, the rotating connection design of the connecting rod also allows medical staff to flexibly adjust the angles between the components according to the support angle and height requirements of the patient's legs, so as to meet the characteristics of the gradual recovery of the patient's leg function during the rehabilitation process.

[0021] Finally, the medical staff will use the first locking knob 103, the second locking knob 203 and the third locking knob 305 to respectively fix the positions of the first connecting rod 4, the second connecting rod 5 and the foot component 3. These locking knobs are connected to the corresponding support plates by threaded connection, which can ensure the stable and reliable connection between the components and prevent the connecting rods from loosening or shifting during the patient's activities, thereby providing a safe and stable support and fixation environment for the patient.

[0022] When the patient uses the device, the inflation adjustment function of the airbag can be adjusted in real time according to the patient's comfort needs, and the length and angle adjustment function of the connecting rod can be optimized according to the different stages of the patient's rehabilitation progress. This highly adjustable and adaptable design enables the device to meet the personalized needs of different patients during postoperative rehabilitation, providing patients with a comfortable and stable support and fixation solution, which helps promote the patient's rehabilitation process and improve the patient's quality of life.
