[0026] Figure 1 This is a front view structural diagram of the present invention in the use state of the arm fixation device after breast cancer surgery. Figure 2 This is a front view structural diagram of the present invention in the unfolded state of the postoperative arm fixation device for breast cancer. Figure 3 FIG. 1 is a schematic diagram of the top cross-section structure of the right connector of the postoperative arm fixation device for breast cancer of the present invention. Figure 1-Figure 3 As shown, the present embodiment provides an arm fixation device for breast cancer surgery, comprising a forearm support 2, an upper arm restraint belt 1, two shoulder straps 3 and a connecting assembly, wherein the forearm support 2 is arranged in the middle of the upper arm restraint belt 1, one end of the two shoulder straps 3 is respectively connected to the upper left and right sides of the forearm support 2, and the connecting assembly is arranged at both ends of the upper arm restraint belt 1. When the patient's forearm is inserted into the forearm support 2, and the upper arm restraint belt 1 is wrapped around the patient's arm and the periphery of the upper arm, the connecting assembly can be used to connect the two ends of the upper arm restraint belt 1 and fix the upper arm to the side of the body.

[0027] It should be noted that cushion layers are provided on both shoulder straps 3 .

[0028] In the above embodiment, the connecting component includes a left connecting part and a right connecting part. The left connecting part is arranged on the left front end of the upper arm restraint belt 1, and the right connecting part is arranged on the right front end of the upper arm restraint belt 1. The left end of the upper arm restraint belt 1 is provided with a connecting transverse belt that can be matched with the right connecting part, and the other ends of the two shoulder straps 3 are provided with connecting longitudinal belts that can be matched with the left connecting part and the right connecting part.

[0029] In the above embodiment, the left connecting part includes a left connecting body 4, in which a longitudinal groove for the connecting longitudinal belt to pass through is provided, and a first clamping member that can be matched with the connecting longitudinal belt is provided in the longitudinal groove.

[0030] In the above embodiment, the right connecting part includes a right connecting body 5, a longitudinal groove is provided in the right connecting body 5 for the connecting longitudinal belt to pass through, a first clamping member that can be adapted to the connecting longitudinal belt is arranged in the longitudinal groove, and a transverse groove is provided in the right connecting body 5 for the connecting transverse belt to pass through, a second clamping member that can be adapted to the connecting transverse belt is arranged in the transverse groove.

[0031] In the above embodiment, the first clamping member includes a first wedge block 6, a first spring 7 and a first pull rod 8. A plurality of positioning holes are evenly arranged on the connecting longitudinal belt. A first accommodating groove is arranged on the side wall of the longitudinal groove. One end of the first spring 7 is connected to the bottom wall of the first accommodating groove, and the other end of the first spring 7 is connected to the first wedge block 6. A first through hole connecting to the outside is arranged on the bottom wall of the first accommodating groove. One end of the first pull rod 8 passes through the first through hole and the first spring 7 in sequence and is connected to one end of the first wedge block 6. When the first spring 7 is in a natural state, the other end of the first wedge block 6 extends out of the first accommodating groove and enters the longitudinal groove. The other end of the first wedge block 6 is arranged in an inclined shape on the side toward which the connecting longitudinal belt is inserted.

[0032] In the above embodiment, the second clamping member includes a second wedge block 9, a second spring 10 and a second pull rod 11. A plurality of positioning holes are evenly arranged on the connecting transverse belt. A second accommodating groove is arranged on the side wall of the transverse groove. One end of the second spring 10 is connected to the bottom wall of the second accommodating groove, and the other end of the second spring 10 is connected to the second wedge block 9. A second through hole connecting to the outside is arranged on the bottom wall of the second accommodating groove. One end of the second pull rod 11 passes through the second through hole and the second spring 10 in sequence and is connected to one end of the second wedge block 9. When the second spring 10 is in a natural state, the other end of the second wedge block 9 extends out of the second accommodating groove and enters the transverse groove. The other end of the second wedge block 9 is arranged in an inclined shape on the side where the connecting transverse belt is inserted.

[0033] Working principle: when in use, the patient's forearm is inserted into the forearm supporting member 2, so that the patient's forearm is placed horizontally, one end of the upper arm restraint belt 1 is passed around the outside of the upper arm to the body, and the other end of the upper arm restraint belt 1 is also passed around the body, and the connecting transverse belt on the upper arm restraint belt 1 is inserted into the transverse groove. As the connecting transverse belt enters the transverse groove, the connecting transverse belt squeezes the inclined side of the second wedge block 9, so that the second wedge block 9 retracts into the second accommodating groove. When the positioning hole on the connecting transverse belt is opposite to the notch of the second accommodating groove, the second spring 10 drives the second wedge block 9 to be inserted into the corresponding positioning hole, so that the connecting transverse belt cannot fall out. The tightness can be adjusted by using the length of the connecting transverse belt passing through the right connector 5, and the two connecting longitudinal belts continue to be inserted into the two longitudinal grooves respectively, and the two shoulder straps 3 are forced to hang on the patient's shoulders.

[0034] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention.
