Problems solved by technology

[0003] At present, rotator cuff training is mostly performed manually by medical staff, and there are also reciprocating electric rehabilitation equipment, but the reciprocating movement of such equipment is generally realized by the positive and negative rotation of the motor, so the motor needs to be frequently reversed.
At the moment when the motor turns and reverses, the impedance of the motor coil is very small, and the current is large at this moment, which is prone to generate heat and cause the risk of motor burnout, affecting the service life of the motor; The electrical energy is greater than the actual energy required, thus causing a waste of electrical energy
In addition, if the motor turns and reverses to realize the reciprocating movement of the shoulder, it is also necessary to record the rehabilitation treatment time. The patient forgets to time the time or the time is wrong, which may easily lead to excessive movement.

Embodiment 1

[0021] In Example 1, such as Figure 1 to 4 As shown, the present invention includes a frame body 7, a housing 11, a No. 1 reel 46, a No. 2 reel 47, a traction rope 4, a weight rope 43, a seat 13 and a motor 41. For ease of description, it is assumed that in this embodiment, the direction where the No. 1 reel 46 is located is forward, and the direction where the motor 41 is located is backward.

[0022] The No. 1 reel 46 and No. 2 reel 47 are respectively located in the upper shell 11 of the frame body 7 and respectively include a No. 1 cylinder body 33, a No. 2 cylinder body 38 and a No. 1 side plate 32 fixed at both ends of the No. 1 cylinder body 33. And the No. 2 side plate 35, the No. 3 side plate 37 and the No. 4 side plate 39 at both ends of the No. 2 cylinder body 38. The numbering sequence is set in the order from front to back. The order is the No. 1 to No. 4 side plates. The side plate 32, the second side plate 35, and the third side plate 37 are circular. The diamete...

Embodiment 2

[0033] Example 2 is more suitable for patients with frozen shoulder, who also have frozen shoulder joint adhesions. Patients with shoulder joint adhesions have very poor joint mobility. If the arm moves too fast, it may cause secondary damage to the stiff joints. For some patients, exercise equipment with speed-limiting devices should be used to help patients with rehabilitation training. In this embodiment, such as Figure 5 to 8 As shown, a gear box 58 is added on the basis of Embodiment 1. In the present invention, the gear box 58 can function as a speed limiter, so that the exercise equipment can run at a slower speed. In this embodiment, the technical features that have nothing to do with the gear box 58 are the same as those in Embodiment 1, and will not be repeated in this embodiment. Since the direction of movement obstacles for frozen shoulder is both forward and lateral extension, the seat 13 can be placed according to the patient’s specific rehabilitation requiremen...

Embodiment 3

[0041] In Embodiment 3, this embodiment is derived on the basis of Embodiment 2. The main structure of this embodiment is the same as that of Embodiment 2. The following only describes the different technical features between this embodiment and Embodiment 2. The same technical features will not be repeated.

[0042] Such as Picture 9 , 10 11, this embodiment also includes a chute rod 26, a sixth gear 28, a seventh gear 30 and a hand wheel 1.

[0043] The protruding end of the slider cylindrical structure 22 is hinged with one end of the connecting rod 25, and the other end of the connecting rod 25 is hinged with the sliding groove rod 26. The chute rod 26 is matedly connected with the rocker 29. The rocker 29 has teeth on one side to form a rack structure. On the rocker 29, on the side opposite to the teeth, there are two sides extending inward and outward. The protruding structure makes the rocker 29 form a T-shaped cross-section, and the sliding groove rod 26 is provided with ...

Abstract

The invention discloses a rotator cuff training device and belongs to the field of medical instruments. The rotator cuff training device is characterized by comprising a frame, a housing, a first drum, a second drum, a traction rope, a counterweight rope, a seat and a motor. An arm is driven to vertically reciprocate under joint action of the motor and arm gravity, so that rehabilitation can be promoted for patients with rotator cuff degeneration and patients with periarthritis of shoulder (adhesive omarthritis). Compared with the prior art, the rotator cuff training device has the advantagesof good safety and low electricity consumption.

Description

Technical field [0001] The invention relates to a medical device, in particular to a rotator cuff training device suitable for rehabilitation of patients with rotator cuff tissue degeneration and frozen shoulder. Background technique [0002] The rotator cuff is a general term covering the anterior, upper, and posterior tendon tissues of the shoulder joint. Its function is to draw the humeral head toward the glenoid during the abduction of the upper arm and maintain the normal fulcrum joint of the humeral head and glenoid. Rotator cuff injury will weaken or even lose this function, seriously affecting the abduction function of the upper limbs. Rotator cuff injuries are mostly treated with minimally invasive arthroscopy, which is less traumatic. It is expected that rehabilitation training will be carried out as soon as possible after the operation to restore shoulder joint function. The core of rotator cuff rehabilitation training is to avoid pushing and pulling instead. That is...
