The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0028] The additional aspects and advantages of the present utility model will become apparent in the following description part, or will be understood through the practice of the present utility model.

[0029] See Figure 1As shown in the figure, a foot auxiliary device for knee joint surgery includes a fixing clip 1, a first straight rod 2, a first corner direction adjusting member 3, a healthy foot supporting plate 4, a second corner direction adjusting member 5, and a diseased foot palm supporting member 6. The fixing clip 1 is used to clamp and fix the foot auxiliary device to the operating table 7. One end of the first straight rod 2 is fixedly connected to the fixing clip 1 and is parallel to the side of the operating table 7. The other end of the first straight rod 2 is fixedly connected to a rotating arm of the first corner direction adjusting member 3. Another rotating arm of the first corner direction adjusting member 3 is connected to one side of the healthy foot supporting plate 4. The other side of the healthy foot supporting plate 4 is connected to a rotating arm of the second corner direction adjusting member 5. Another rotating arm of the second corner direction adjusting member 5 is connected to the diseased foot palm supporting member 6. The diseased foot palm supporting member 6 is lapped on the upper side of the tail of the operating table 7.

[0030] A foot auxiliary device for knee joint surgery provided in this embodiment can not only place the healthy foot steadily on the healthy foot supporting plate 4, effectively avoiding the discomfort caused by the healthy foot hanging in the air, but also support the diseased foot palm on the diseased foot palm supporting member 6 to maintain the flexion angle for easy operation by the surgeon. At the same time, the rotation angles of both the first corner direction adjusting member 3 and the second corner direction adjusting member 5 are not less than 180°, so that the foot auxiliary device can be used on both the left and right sides of the operating table 7 to meet different installation requirements.

[0031] It should be noted that for the convenience of assembling the foot auxiliary device, one or several of the above-mentioned components can be an integrally formed structure connected in advance. The adjacent components in a split form are locked and fixed by inserting a thick rod and a thin rod into each other.

[0032] In this embodiment, it is preferred that the healthy foot supporting plate 4 and the second corner direction adjusting member 5 are connected in advance as an integral body. The healthy foot supporting plate 4 is connected to the first corner direction adjusting member 3 through a second straight rod 8. In this way, according to the actual size of the operating table 7, the length of the second straight rod 8 can be adjusted to match operating tables 7 of different scales. In some embodiments, the healthy foot supporting plate 4 is connected in advance as an integral body with the first corner direction adjusting member 3 and the second corner direction adjusting member 5; this is not limited to this embodiment.

[0033] In this embodiment, it is preferred that the diseased foot palm supporting member 6 is an L-shaped member, and it is preferred that a sponge sleeve 9 is sleeved on the diseased foot palm supporting member 6. In this way, not only is the structure compact and the connection convenient, but also the supporting area and comfort of the diseased foot palm can be enhanced.

[0034] Refer to Figure 2As shown, the fixing clip 1 has a first clamping opening 101 for clamping and fixing to the operating table 7 and a second clamping opening 102 for clamping and fixing to the first straight rod member. A first locking screw 103 and a second locking screw 104 are respectively provided on the first clamping opening 101 and the second clamping opening 102. During clamping, the clamping force is controlled by the locking screws, and the clamping and disassembly are convenient, and the clamping is firm and reliable. Obviously, those skilled in the art can also adopt other clamping structures known in the prior art or that can be realized in the future according to different actual needs, not limited to this embodiment.

[0035] Referring to Figure 3 As shown, the thick rod 10 and the thin rod 11 are inserted and locked with each other to form a locking and fixing structure with adjustable insertion depth. A third locking screw 12 is provided on the thick rod 10. After the thin rod 11 is inserted to a predetermined depth, tightening the third locking screw 12 can lock the insertion depth of the thick rod 10 and the thin rod 11. In this way, the size of the foot auxiliary device can meet the use and assembly requirements of different patients and different hospital beds.

[0036] Combined with Figure 3 As shown, the corner direction adjusting member is a serrated universal rotating head, which is convenient for use on the left and right sides. The universal rotating head includes a first serrated surface 13 and a second serrated surface 14 that cooperate with each other, and the first serrated surface 13 and the second serrated surface 14 are locked with a fourth locking screw 15. During operation, loosening the fourth locking screw 15 can adjust the rotation angle between the first serrated surface 13 and the second serrated surface 14. After the angle rotation is in place, tightening the fourth locking screw 15 locks and fixes the first serrated surface 13 and the second serrated surface 14. At this time, due to the engagement of the serrated surfaces, the two cannot rotate. Obviously, those skilled in the art can also adopt other structural forms of corner direction adjusting members known in the prior art or that can be realized in the future according to different actual needs, not limited to this embodiment.

[0037] Combined with Figure 4 As shown, in some embodiments, a healthy foot supporting pad 16 and a healthy foot strap are further installed on the healthy foot supporting plate 4. The healthy foot supporting pad 16 is shaped according to the physiological structure of the foot. The soft pad is provided with a heel part 1601 and a sole part 1602. A groove 1603 for placing the heel is provided in the heel part 1601, and a wrapping part 1604 for wrapping the sole and toes is provided on the sole part 1602. The wrapping part 1604 is composed of two sponge pads, and the two sponge pads can be movably lifted and covered. The two sponge pads are bonded by a magic tape, which is convenient for lifting and covering operations; the healthy foot strap assists in fixing the healthy foot, and thus firmly fixes it to prevent slipping and avoid accidents. For the convenience of assembling the healthy foot strap, a through hole 401 for threading the healthy foot strap is preferably provided on the healthy foot supporting plate 4.

[0038] In some embodiments, it is preferred that the healthy foot support plate 4 is a rectangular metal plate, and it is preferred that the healthy foot support pad 16 is adhesively fixed to the healthy foot support plate 4 through Velcro, so as to facilitate disassembly and replacement according to different actual needs.
