[0004] In summary, the prior art uses an upper supporting plate and a lower supporting plate to support and fix the patient's leg, but this method has the following technical problems: when the external temperature is low, a thermal blanket is generally needed to cover the patient's leg to reduce the low temperature of the patient's leg, and the above device lacks a structure for separating the thermal blanket from the patient's skin, which may cause the thermal blanket to compress the patient's wound or the thermal blanket to move relative to the skin near the patient's wound, thereby affecting the healing of the patient's wound.

[0059] The support with leg support and fixing functions provided in Embodiment 1 is further optimized, specifically as shown in Figure 1 and Figure 11As shown, the supporting mechanism 43 comprises a supporting plate 44, the inner wall of the device base 1 is fixedly connected with the supporting plate 44, the top of the supporting plate 44 is fixedly connected with a fixed screw rod 45, the outer part of the fixed screw rod 45 is threadedly connected with a rotating shell 46, the top of the rotating shell 46 is rotatably connected with a supporting block 47, the top of the supporting plate 44 is fixedly connected with a straight rod 49, the outer part of the straight rod 49 is slidably connected with a sliding shell 48, and the sliding shell 48 is fixedly connected to the bottom of the supporting block 47.

[0060] Through the above structural design, when the patient's leg is fixed, the rotating shell 46 can be rotated, so that the overall length of the rotating shell 46 and the fixed screw rod 45 changes, the height of the supporting block 47 changes under the limitation of the sliding shell 48 and the straight rod 49, the height of the supporting block 47 can be adjusted to the height corresponding to the patient's foot, and then the patient's foot can be placed on the supporting block 47, and the supporting block 47 supports the patient's foot.

[0061] The mounting mode, connecting mode or setting mode of the support with leg supporting and fixing functions is a common mechanical mode, and as long as the beneficial effects can be achieved, it can be implemented. The electric telescopic rod 5 of the support with leg supporting and fixing functions is purchased on the market, and the technical personnel in the industry only needs to install and operate according to the attached instruction manual, without the creative labor of the technical personnel in the field.
