[0032] Now, in conjunction with the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.

[0033] like Figures 1 to 4 As shown, the utility model provides a preferred embodiment of a shoulder joint training device after breast cancer surgery.

[0034] A shoulder joint training device after breast cancer surgery includes: a shoulder fixing structure, a support rod 300 and an elastic band 400, wherein the shoulder fixing structure includes a chest strap 100 and a shoulder strap 200, wherein the shoulder strap 200 includes an arc-shaped mounting cavity 201 arranged along the length direction, and a first arc-shaped opening is provided at one horizontal end of the arc-shaped mounting cavity 201 close to the outside; the support rod 300 is inserted into the arc-shaped mounting cavity 201 through the first arc-shaped opening and can move in the arc-shaped mounting cavity 201; one end of the elastic band 400 and the end of the support rod 300 are provided with a flip adjustment structure 700, and the elastic band 400 is provided with a flip adjustment structure 700. A finger ring 500 is provided at the other end of the belt 400, and the elastic belt 400 is flipped and positioned with the support rod 300 through the flip adjustment structure 700; wherein, the upper and lower end surfaces (210, 220) of the arc-shaped mounting cavity 201 are both provided with first positioning holes 230, and the first positioning holes 230 are arranged at intervals, and the support rod 300 is provided with a second positioning hole 320. The shoulder joint training device after breast cancer surgery also includes a first positioning column 240, and the first positioning column 240 passes through the first positioning hole 230 and the second positioning hole 320 to position the support rod 300 on the arc-shaped mounting cavity 201.

[0035] In an embodiment of the shoulder fixation structure, the chest strap 100 and the shoulder strap 200 form part of the shoulder fixation structure, used to secure the device to the patient and ensure that other components are positioned correctly. After the chest strap 100 is secured around the chest, the shoulder strap 200 is secured around one shoulder, such that the first arcuate opening of the arcuate mounting cavity 201 faces left or right.

[0036] Regarding the design of inserting the support rod 300 into the arc-shaped mounting cavity 201, first, the support rod 300 is inserted into the first arc-shaped opening of the arc-shaped mounting cavity 201, and the second positioning hole 320 corresponds to the corresponding first positioning hole 230. The first positioning hole 230 is provided in the middle and is arranged at intervals on both sides along the length direction of the shoulder strap 200. When the second positioning hole 320 is aligned with the first positioning hole 230 in the middle, the support rod 300 is in the middle of the shoulder and is arranged horizontally. If the second positioning hole 320 is aligned with the first positioning holes 230 on both sides, the support rod 300 is set in a front or back position. By adjusting the different positions of the support rod 300, the patient's arm can be exercised at different front and back angles, thereby effectively training the shoulder joint after breast cancer surgery. Among them, the front and back angle refers to the front and back direction relative to the patient's own body as a reference system. At the same time, in conjunction with the flip adjustment structure 700, not only can the patient's arm be exercised at different front and back angles, but also outward (left or right) expansion angle training can be achieved, thereby achieving shoulder joint training in a multi-angle range.

[0037] In an embodiment of the elastic band 400, the elastic band 400 is generally made of a soft material with a certain elasticity, such as rubber or elastic fabric. One end of the elastic band 400 is connected to the end of the support rod 300, and the other end is provided with a finger ring 500, which is placed on the finger for the convenience of the patient to use. The main function of the elastic band 400 is to provide an appropriate amount of resistance to help the patient perform shoulder joint training. By stretching the elastic band 400, the patient needs to overcome the resistance to complete the exercise, thereby strengthening muscle strength and stability. According to the patient's rehabilitation needs and training stage, elastic bands 400 of different strengths can be selected to meet different training requirements. In addition, the elastic band 400 is fixedly arranged to rotate with the support rod 300 through the flip adjustment structure 700, and the end position of the elastic band 400 is extended by the support rod 300, so that the arm will not be touched during training, and corresponding front and rear angles and expansion angles are provided.

[0038] The finger ring 500 is a ring-shaped structure made of a soft and comfortable material, such as rubber, fabric or leather, which allows the patient to easily hold or wear it to perform training movements.

[0039] In this embodiment, the shoulder strap 200 is made of a hard material, the chest strap 100 is made of an elastic material or fabric, and the chest strap 100 is connected to both ends of the shoulder strap 200 via a connecting strap 600, and the connecting strap 600 is made of an elastic material or fabric.

[0040] The shoulder strap 200 is constructed of a hard material with a certain degree of hardness and rigidity, such as plastic, ABS, or polycarbonate, to provide better support and fixation for the support rod 300, maintaining the correct position of the support rod 300 on the shoulder. The bottom of the shoulder strap 200, i.e., the end surface that contacts the human body, can be padded to improve wearing comfort.

[0041] The chest strap 100 is made of an elastic material or fabric. Elastic materials, such as rubber or spandex, have a certain degree of stretchability and elasticity, while fabric is a soft textile material. The chest strap 100 is designed to provide a comfortable fit and flexibility, making it comfortable for the patient while wearing it, while also ensuring the flexibility and adaptability of the shoulder strap 200.

[0042] The connecting strap 600 connects the two ends of the shoulder strap 200 and is used to adjust and fix the position of the entire device on the patient, adjust and adapt to the body sizes of different patients, and provide a certain degree of elasticity to ensure comfort and stability. The connecting strap 600 ensures a firm connection between the shoulder strap 200 and the chest strap 100 to avoid loosening or falling off during use.

[0043] In this embodiment, the chest strap 100 and the connecting strap 600 are integrally formed.

[0044] The chest strap 100 and connecting strap 600 are integrally formed, joined together through thermoforming, injection molding, or sewing to form a continuous, seamless structure. This one-piece design simplifies the assembly structure, reduces the number of connection points between components, reduces device complexity, improves device stability and reliability, and reduces the risk of loosening or falling off.

[0045] like Figures 1 to 4 As shown, the present invention provides a preferred embodiment of the arc-shaped installation cavity 201 .

[0046] A second arc-shaped opening is provided at one horizontal inner end of the arc-shaped installation cavity 201 , and the support rod 300 includes two limiting members 310 , which are respectively provided on the outside of the first arc-shaped opening and the second arc-shaped opening.

[0047] The stopper 310 is a small protrusion or projection to ensure that the support rod 300 is fixed in the arc-shaped installation cavity 201. The distance between the two stoppers 310 is adapted to the width of the arc-shaped installation cavity 201, thereby firmly fixing and limiting the support rod 300 in the arc-shaped installation cavity 201.

[0048] The limit member 310 provides a limiting and fixing function when the support rod 300 is inserted into the arc-shaped mounting cavity 201, ensuring that the support rod 300 is in the correct position and preventing accidental detachment. The support rod 300 is restricted during movement or use, thereby effectively preventing the support rod 300 from detaching from the arc-shaped mounting cavity 201.

[0049] like Figures 4 to 6 As shown, the present invention provides a preferred embodiment of a flip adjustment structure 700 .

[0050] The flip adjustment structure 700 includes a first rotating shaft portion 710 set on the support rod 300, and a second rotating shaft portion 720 set on the elastic band 400, and the first rotating shaft portion 710 and the second rotating shaft portion 720 are rotatably set; the flip adjustment structure 700 also includes a positioning mechanism set between the first rotating shaft portion 710 and the second rotating shaft portion 720.

[0051] The support rod 300 is provided with a first pivot portion 710, which allows the elastic band 400 to rotate or adjust within a certain range. The elastic band 400 is provided with a second pivot portion 720, which is used to connect to the first pivot portion 710 to achieve a suitable wearing position or angle. A positioning mechanism is provided between the first pivot portion 710 and the second pivot portion 720 to ensure accurate positioning and alignment during adjustment to achieve the preset deployment angle.

[0052] Specifically, the first rotating shaft portion 710 and the second rotating shaft portion 720 rotate around, and the positioning mechanism includes a first positioning plate 730 arranged on the first rotating shaft portion 710, and a second positioning plate 740 arranged on the second rotating shaft portion 720. The first positioning plate 730 includes a plurality of third positioning holes 731 at a distance D from the central axis 701, and the second positioning plate includes a fourth positioning hole 741 at a distance D from the central axis 701. The fourth positioning hole 741 is aligned with each third positioning hole 731 during the rotation of the first rotating shaft portion 710 and the second rotating shaft portion 720; wherein, the positioning mechanism also includes a second positioning column 750, and the second positioning column 750 passes through the third positioning hole 731 and the fourth positioning hole 741 to position the first rotating shaft portion 710 and the second rotating shaft portion 720.

[0053] The specific adjustment process is as follows: the first rotating shaft portion 710 and the second rotating shaft portion 720 are hinged, and the hinge axis of the two is defined as the central axis 701. The first rotating shaft portion 710 and the second rotating shaft portion 720 both rotate relative to each other around the central axis 701. In addition, the first positioning plate 730 is disposed on the upper end surface of the first rotating shaft portion 710 and is arranged perpendicular to the first rotating shaft portion 710. Similarly, the second positioning plate is disposed on the upper end surface of the second rotating shaft portion 720 and is arranged perpendicular to the second rotating shaft portion 720. In other words, the first positioning plate 730 and the second positioning plate are arranged in parallel, preferably overlapping and affixed.

[0054] In actual operation, the first rotating shaft portion 710 is fixed on the support rod 300 and does not move, and the second rotating shaft portion 720 rotates around the central axis 701. During the rotation, the fourth positioning hole 741 of the second positioning plate is continuously aligned with the third positioning holes 731 of the first positioning plate 730. After the second positioning column 750 is in an overlapping alignment state, it passes through the third positioning hole 731 and the fourth positioning hole 741 to position the first rotating shaft portion 710 and the second rotating shaft portion 720.

[0055] Preferably, the first positioning plate 730 and the second positioning plate are both semicircular structures, with the first positioning plate 730 extending forward beyond the central axis 701, and the second positioning plate extending forward beyond the central axis 701. A plurality of third positioning holes 731 are spaced around the outer edge of the first positioning plate 730, and the fourth positioning hole 741 is provided at the farthest corner of the second positioning plate away from the elastic band 400, thereby enabling the first rotating shaft portion 710 and the second rotating shaft portion 720 to be positioned within a range from 90 degrees downward to 180 degrees horizontally, wherein 90 degrees downward refers to a state in which the second rotating shaft portion 720 is vertically downward and the first rotating shaft portion 710 is horizontally arranged. The entire process assumes that the first rotating shaft portion 710 is in a horizontal arrangement.

[0056] Furthermore, the first positioning plate 730 is provided with an avoidance space 732 at the central axis 701, and the avoidance space 732 is extended at the central axis 701 and away from the first positioning plate 730; wherein, the second rotation axis portion 720 is an L-shaped structure, and the bending portion of the L-shaped structure is a rotation axis protrusion, and the rotation axis protrusion is hinged to the rotation axis groove portion of the first rotation axis portion 710.

[0057] Since the second rotating shaft portion 720 is an L-shaped structure, the second rotating shaft is higher than the first rotating shaft portion 710 in the horizontal state of 180 degrees. The purpose of the avoidance space 732 is to avoid the second rotating shaft portion 720 in the horizontal state of 180 degrees.

[0058] In this embodiment, the second shaft portion 720 is formed as an injection molded part and is injection molded onto the elastic band 400, thereby achieving an integrated arrangement of the second shaft portion 720 and the elastic band 400. Since the support rod 300 is made of a hard material, the support rod 300 and the first shaft portion 710 can be integrally formed.

[0059] The above description is only the best embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes or modifications made within the scope of the patent application of the present invention are covered by the present invention.
