[0029] Embodiment 1, below is combined with the attached Figure 1-6 This application is described in further detail.

[0030] An embodiment of the present application discloses an arm fixation device for treating liver cancer patients, comprising an arm fixation frame 10 and a limiting rod 14 threadedly fixed to the outside of the arm fixation frame 10 by bolts. The arm fixation frame 10 is integrally welded and fixed to one end of the arm fixation frame 10, so that the patient's middle finger can be simply limited by the arm fixation frame 10 during use.

[0031] Please refer to Figure 4 One end of the first strap 11 is fixed to the arm fixing frame 10 by a bolt thread, and the bottom of the first clamping member 12 is fixed to the top of the arm fixing frame 10 by a bolt thread. One end of the first strap 11 is passed through the first clamping member 12, so that the first strap 11 and the first clamping member 12 are clamped and fixed. The arm fixing frame 10 can be fixed to the patient's arm for the first time through the two first straps 11. (Note: The relationship between the first strap 11 and the first clamping member 12 is exactly the same as the strap principle in real life, so it is not described in detail in the article).

[0032] Please refer to Figure 5The arm limiting ring 21 is sleeved on the outside of the arm fixing frame 10 and is movably connected to the arm fixing frame 10. The second tie 22 is fixed to one end of the arm limiting ring 21 by a bolt thread. The other end of the arm limiting ring 21 is fixed to a second clamping member 23 by a bolt thread. One end of the second tie 22 is passed through the second clamping member 23, so that the second tie 22 and the second clamping member 23 are clamped and fixed. The arm limiting ring 21 can be tightened or enlarged by the two second tie ties 22, and the fixation between the arm and the arm fixing frame 10 can be strengthened by the arm limiting ring 21 (Note: The relationship between the second tie 22 and the second clamping member 23 is exactly the same as the tie principle in real life, so it is not described in detail in the text).

[0033] Please refer to Figure 1 One end of the limit rod 14 is sleeved on the outside of the connecting rod 30 and is movably connected to the connecting rod 30. When the position of the arm limit circle 21 needs to be adjusted, the arm limit circle 21 can be slid left and right so that the arm limit circle 21 slides left and right on the outside of the connecting rod 30. When the position of the arm limit circle 21 needs to be fixed, a bolt is passed through the L-shaped connecting plate 20 and the nut is tightened so that the L-shaped connecting plate 20 is limited to the outside of the connecting rod 30. (Note: The connection method between the limit rod 14 and the connecting rod 30 is exactly the same as the connection method between the L-shaped connecting plate 20 and the connecting rod 30, so it is not described in detail in the text).

[0034] Please refer to Figure 6 , U-shaped limit pieces 31 are welded and fixed at both ends of the connecting rod 30. When the connecting rod 30 needs to be connected to the guardrail on the bed, the U-shaped limit piece 31 is clamped on the guardrail, and bolts are passed through both ends of the U-shaped limit piece 31. The nuts are turned to tighten the U-shaped limit piece 31 inward, so that the U-shaped limit piece 31 will be threaded and fixed on the guardrail (Note: the shape of the limit rod 14 and one end of the L-shaped connecting plate 20 is exactly the same as the U-shaped limit piece 31, and the operation method is also the same, so it is not described in detail in the text).

[0035] Working principle and process of this utility model:

[0036] The U-shaped limit piece 31 is clamped on the guardrail on one side of the bed, and the U-shaped limit piece 31 is threadedly fixed on the guardrail with bolts, and the limit rod 14 is threadedly fixed on the connecting rod 30 in the same way. First, one end of the L-shaped connecting plate 20 is clamped on the outside of the connecting rod 30, and the L-shaped connecting plate 20 is moved until the arm limit ring 21 is sleeved on the outside position of the arm fixing frame 10, and then the patient's arm is placed in the arm fixing frame 10 with the palm facing up, so that the patient's arm is embedded in the arm fixing frame 10, and the first tie 11 is passed through the first clamping piece 12, and the first tie 11 is pulled to one end until the inner wall of the first tie 11 fits the patient's arm, and the second tie 22 is connected to the second clamping piece 23 in the same way, so that the patient's arm is limited on the arm fixing frame 10 for the second time, and the patient's fingers will also be simply limited by the finger limit ring 13 when using the equipment later.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
