[0023] As per the instruction manual Figure 1-3 As shown:

[0024] A rehabilitation training device for trigger finger includes: a first support body 100, a second support body 110, a straightening structure 200, and a straightening airbag 300; the second support body 110 is fixedly disposed on the top surface of the first support body 100; the straightening structure 200 is disposed at the position corresponding to the back of the thumb of the first support body 100 and the second support body 110; and the straightening airbag 300 is disposed at the position corresponding to the pad of the thumb of the first support body 100 and the second support body 110.

[0025] In this embodiment, the first support body and the second support body constitute the support body of the rehabilitation training device for trigger finger. The first support body is fitted onto the patient's palm, and the second support body is used to fix the thumb. The straightening structure stretches the thumb to a straight state, and at the same time, the straightening airbag fills with gas to help the thumb maintain the straight state, thereby providing conservative treatment for trigger finger and reducing the probability of surgical treatment.

[0026] Specifically, the straightening structure 200 includes: a first threading tube 210 and a second threading tube 220; the first threading tube 210 is fixed to the back surface 115 of the second supporting body, and the first threading tube 210 includes a top fixing plate 215, one end of the tensioning wire 205 is fixedly connected to the top fixing plate 215; the second threading tube 220 is fixed at the connection between the back surface 115 of the second supporting body and the back surface 105 of the first supporting body, and the tensioning wire 205 passes through the second threading tube 220.

[0027] Specifically, the tension line 205 is stably subjected to the force from the top fixing plate 215 during the straightening process, thus ensuring the stability of the entire straightening structure during operation. The tension line 205 extending out of the first threading tube 210 passes through the second threading tube 220. When the tension line 205 is tightened, it can drive the second bearing body 110 to act on the thumb, generating a continuous and stable tension, which helps to straighten the thumb trigger finger, improve the flexion state of the thumb, and thus achieve the purpose of rehabilitation training.

[0028] In this embodiment, the first threading tube is fixed to the back of the second support body, and its top fixing plate is connected to one end of the tension line. When the tension line is pulled, it can apply a stable tension to the thumb, pulling the thumb from a bent state to a straight state. At the same time, the second threading tube is fixed to the connection between the back of the second support body and the back of the first support body, and the tension line is threaded through it, ensuring that the tension line can move smoothly along the predetermined path during the pulling process, avoiding deviation or jamming of the tension line, thereby improving the stability and reliability of the stretching action and enhancing the durability of the rehabilitation training device for trigger finger.

[0029] Specifically, the straightening structure 200 also includes: a third threading tube 230; the third threading tube 230 is fixed to the back side 105 of the first bearing body, and the tensioning wire 205 passes through the third threading tube 230.

[0030] Specifically, the third threading tube 230 provides stable support and guidance for the stretching line 205 during the rehabilitation training process of the trigger finger rehabilitation training device, ensuring the stability and reliability of the entire device.

[0031] Specifically, the rehabilitation training device for trigger finger also includes: a wrist support body 120; the wrist support body 120 is fixedly mounted on the bottom surface of the first support body 100. The wrist support body 120 is an elastic sleeve that wraps around the patient's wrist, improving the stability of the rehabilitation training device for trigger finger and preventing the glove from sliding downwards during hand movements.

[0032] Specifically, the straightening structure 200 also includes: a fourth threading tube 240; the fourth threading tube 240 is fixed at the connection between the back of the first bearing body 105 and the back of the wrist bearing body 125, and the tensioning wire 205 passes through the fourth threading tube 240.

[0033] Specifically, the extension airbag 300 is fixed at the connection between the front 116 of the second load-bearing body and the front 106 of the first load-bearing body.

[0034] Specifically, the bottom of the extension airbag 300 is connected to an air supply tube 310; the air supply tube 310 is embedded within the fabric of the front surface 106 of the first support body and the front surface 126 of the wrist support body. Placing the extension airbag 300 on the thumb pad allows it to directly act on the affected tendon and tendon sheath. During inflation, it provides a gentle, counter-traction force to the flexed, contracted tendon, helping the thumb gradually straighten and more precisely targeting the pathogenesis of trigger finger.

[0035] Specifically, the rehabilitation training device for trigger finger is equipped with two or more straightening structures 200. Multiple straightening structures 200 can distribute the stretching force, allowing the thumb to be stretched precisely, avoiding overstretching or insufficient stretching of the thumb due to the concentrated force of a single straightening structure, thereby better improving the flexion state of the trigger finger and enhancing the stretching effect.

[0036] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0037] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
