Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 - Figure 8 As shown, this embodiment provides a limb fixing frame, including a support plate 1, and also includes:

[0031] The movable plate 2 is symmetrically arranged above the supporting plate 1;

[0032] The hand fixing components are respectively arranged above the two movable plates 2 and are used to fix the patient's hands;

[0033] The connecting plate 3 is located above the supporting plate 1;

[0034] The leg fixing assembly is symmetrically arranged above the connecting plate 3 and is used to fix the patient's legs;

[0035] The restraint components are arranged on the front end surface and the rear end surface of the support plate 1 and are used to restrain the patient's body, thereby improving the fixation effect of the patient's limbs.

[0036] The above working principle: when it is necessary to fix the patient's limbs, just let the patient lie flat on the support board 1 first, and then use the hand fixing component to effectively fix the patient's hands. After the patient's hands are fixed, use the leg fixing component to fix the patient's legs. When the patient's legs are also fixed, the patient's hands and legs can be effectively fixed, thereby preventing the patient's hands and legs from moving during surgery or infusion, affecting the patient's surgical treatment and infusion effects. When it is necessary to further strengthen the fixation effect of the device on the patient, only the restraint component can be used to conveniently and effectively restrain the patient's body. At this time, the fixation effect of the device on the patient's limbs can be further strengthened, saving time and effort.

[0037] In order to effectively fix the patient's hand, the hand fixing assembly includes lower arc plates 29 respectively arranged on the upper surfaces of the two movable plates 2, the upper surfaces of the two movable plates 2 are fixedly connected with adjustment plates 27, the inner bottom ends of the two adjustment plates 27 are rotatably connected with first screw rods 25, the top ends of the two first screw rods 25 extend to the outside of the adjustment plate 27 and are fixedly connected with first knobs 24, the outsides of the two first screw rods 25 are threadedly connected with threaded plates 26, the outsides of the two adjustment plates 27 are provided with guide grooves for the threaded plates 26 to move, the upper surfaces of the two movable plates 2 are fixedly connected with guide rods 15, the top ends of the two guide rods 15 are fixedly connected with limit plates 16, The inside of the two threaded plates 26 is provided with a guide groove for the guide rod 15 to move. The bottom of the two threaded plates 26 is fixedly connected to the upper arc plate 28. When the patient's hand needs to be fixed, the patient's hand only needs to be placed on the lower arc plate 29 first, and then the first knob 24 is turned. At this time, the first knob 24 will drive the first screw rod 25 to rotate synchronously, and the threaded plate 26 will move synchronously outside the first screw rod 25, driving the upper arc plate 28 to move synchronously. At this time, the patient's hand can be effectively fixed by the cooperation between the upper arc plate 28 and the lower arc plate 29. Through the setting of the guide rod 15, the stability of the threaded plate 26 during movement can be effectively improved.

[0038] Considering that when performing limb fixation treatment on different patients, it is necessary to adjust the distance between the two hand fixation components according to the patient's body shape, a transmission plate 7 is fixedly connected to the bottom of the support plate 1, and the inner wall of the transmission plate 7 is rotatably connected to the first bidirectional threaded rod 8.

The upper surfaces of the two thread blocks 9 are respectively fixedly connected to the bottoms of the two movable plates 2. When it is necessary to adjust the distance between the two hand fixation components, it is only necessary to rotate the second knob 10. At this time, the second knob 10 will drive the first bidirectional threaded rod 8 to rotate synchronously, and the thread block 9 will move synchronously on the outside of the first bidirectional threaded rod 8, driving the movable plate 2 to move synchronously, and the movable plate 2 will drive the hand fixation component to move synchronously. At this time, the distance between the two hand fixation components can be effectively adjusted, so that the hand fixation component can effectively fix the hands of patients with different body shapes.

At this time, the patient's legs can be effectively fixed by the cooperation between the fixing strap 32 and the placement plate 17.

[0040] In order to effectively adjust the distance between the two placement plates 17, so that the leg fixing assembly can effectively fix the legs of patients of different body sizes, the inner wall of the connecting plate 3 is rotatably connected with a second bidirectional threaded rod 22, the other end of the second bidirectional threaded rod 22 extends to the outside of the connecting plate 3 and is fixedly connected with a third knob 21, and the outside of the second bidirectional threaded rod 22 is symmetrically provided with moving blocks 23, and the upper surface of the connecting plate 3 is provided with a guide groove for the moving blocks 23 to move, and the upper surfaces of the two moving blocks 23 are respectively fixedly connected to the bottom of the two placement plates 17. When the distance between the two placement plates 17 needs to be adjusted, only the third knob 21 needs to be rotated. At this time, the third knob 21 will drive the second bidirectional threaded rod 22 to rotate synchronously, and the moving block 23 will move synchronously on the outside of the second bidirectional threaded rod 22, driving the placement plate 17 to move synchronously. At this time, the distance between the two placement plates 17 can be adjusted according to actual needs.

[0041] In addition, in order to effectively adjust the distance between the leg fixing assembly and the hand fixing assembly, the bottom of the support plate 1 is fixedly connected to the bottom of the support plate 1, and the inner side wall of the bottom plate 11 is rotatably connected to the second screw rod 13, the other end of the second screw rod 13 extends to the outside of the bottom plate 11 and is fixedly connected to the fourth knob 12, and the external thread of the second screw rod 13 is connected to the adjustment block 14, and the contact surfaces of the bottom plate 11 and the support plate 1 are provided with guide grooves for the movement of the adjustment block 14, and the upper surface of the adjustment block 14 is fixedly connected to the bottom of the connecting plate 3. When it is necessary to adjust the distance between the leg fixing assembly and the hand fixing assembly, it is only necessary to rotate the fourth knob 12. At this time, the fourth knob 12 will drive the second screw rod 13 to rotate synchronously, and the adjustment block 14 will move synchronously on the outside of the second screw rod 13, driving the connecting plate 3 to move synchronously, and the connecting plate 3 will drive the leg fixing assembly to move synchronously.

When it is necessary to further improve the fixing effect of the device on the patient, it is only necessary to press the plug-in rod 35 first. At this time, the plug-in rod 35 will simultaneously squeeze the telescopic rod 34 and the return spring 36, and then the mounting block 20 is plugged into the interior of the fixed frame 19. At this time, the mounting block 20 will drive the plug-in rod 35 to move synchronously. When the mounting block 20 drives the plug-in rod 35 to move into the guide grooves on both sides of the outer wall of the fixed frame 19, the return spring 36 is reset, driving the plug-in rod 35 to move synchronously. When the plug-in rod 35 is plugged into the guide grooves on both sides of the outer wall of the fixed frame 19, the mounting block 20 can be fixed to the fixed frame 19. At this time, the patient's body can be restrained by the restraining strap 6, thereby further improving the fixing effect of the device on the patient.
