Description

Technical Field

[0001] The utility model relates to the technical field of shoulder joint surgery, in particular to an arm rehabilitation training device after shoulder joint surgery. Background Art

[0002] At present, there is an axillary debridement process in shoulder joint surgery, that is, the dead flesh or rotten flesh in the patient's armpit is excavated, and the skin in the armpit is sutured after subsequent debridement. After the shoulder joint surgery, the patient's arm is difficult to open due to the lack of original muscle tissue and skin tissue at the suture, resulting in restrictions on the patient's daily life. Therefore, the patient needs to perform self-rehabilitation training after the surgery and after the skin in the patient's armpit heals, that is, the operated arm is lifted by the unoperated arm, and the patient's initial lifting angle is low, and the inclination angle between the arm raised and the patient's waist is approximately 30 degrees, and the muscle tissue and skin have a certain elasticity. After a long period of lifting and falling, the angle will reach 140 degrees, but the patient needs to lift the operated arm with the unoperated arm from time to time. The whole process is time-consuming and laborious, and it is difficult for the patient to maintain it for a long time. At the same time, the patient's unoperated arm is difficult to perform other operations during rehabilitation training, that is, affecting daily life. The prior art also lacks a device for cooperating with the patient's arm for rehabilitation tension training after shoulder joint surgery. Utility Model Content

[0005] The benefits of adopting the above technical solution are: the user or other operator wears the belt on the user and initially fixes and supports the belt through the shoulder straps to prevent the belt from slipping or shifting, and then the operator adjusts the inclination angle between the support rod and the fixing plate through the first adjusting member so that the bracket is more closely fitted to the highest point where the patient's arm is raised, that is, the rotation of the shaft drives the support rod to swing in the swing groove so that the first adjusting member can adjust the inclination angle between the support rod and the fixing plate, and then adjusts the length of the support rod through the second adjusting member to ensure that the user's arm can be placed on the bracket. At this time, the user's arm maintains a certain tension state and leans on the bracket, and by maintaining the tension state for a long time, the patient's skin and muscle tissue are elastically tensioned to adapt to this degree of arm opening, and when the skin and muscle tissue adapt to this degree of tension state, the inclination angle between the support rod and the fixing plate can be further adjusted through the first adjusting member, so that the user's arm can be more relaxed than before. The user can perform tension rehabilitation training at a larger inclination angle until the user's arm can be fully opened; the above-mentioned technical setting frees the user's hands, so that the user does not need the non-operated arm to support the operated arm, thereby allowing the user's non-operated arm to perform other operations and can also perform rehabilitation training in daily life, that is, other operations can be performed while undergoing rehabilitation training, and the entire rehabilitation training process is no longer time-consuming and laborious, while improving the efficiency of rehabilitation training; the waist belt in the above-mentioned technology is an existing technology, which can be tied to the user through adjustment structures such as buckles to improve the stability of the waist belt; a soft pad can be provided on the inner wall surface of the waist belt in the above-mentioned technology, and the soft pad is made of elastic material and is close to the fixed block to ensure that when the bracket is subjected to force and transmitted to the waist belt, the waist belt avoids contusion and other effects on the user's waist through the setting of the soft pad; the shoulder strap in the above-mentioned technology can be adjusted and installed according to actual production and use requirements to adapt to the patient's body shape.

[0006] The utility model is further configured as follows: an adjustment hole is coaxially provided on one side of the fixed block corresponding to the position of the rotating hole, the adjustment hole is connected to the rotating hole and the diameter of the adjustment hole is larger than the diameter of the rotating shaft, the first adjusting member includes a socket inserted in the adjustment hole, the socket is provided with a socket for inserting the starting end of the rotating shaft, a first tooth pattern is circumferentially provided on the outer circumferential wall of the socket, a first tooth groove for meshing with the first tooth pattern is circumferentially provided on the inner circumferential wall of the adjustment hole, a second tooth pattern is circumferentially provided on the outer circumferential wall of the starting end of the rotating shaft, and a second tooth groove for meshing with the second tooth pattern is circumferentially provided on the inner circumferential wall of the socket.

[0007] The advantages of adopting the above technical solution are as follows: when it is necessary to adjust the angle between the bracket and the user's waist, the user or other operators assist the user in the operation, that is, to pull the sleeve out of the socket so that the sleeve is no longer matched with the shaft. At this time, the shaft can rotate axially in the rotating hole, so that the operator or user can swing the support rod. After the inclination angle between the support rod and the user's waist is adjusted, the operator inserts the sleeve so that the sleeve is plugged into and matched with the adjustment hole, and the socket is plugged into and matched with the beginning of the shaft. The sleeve is fixed in the adjustment hole by the complete engagement of the first tooth pattern with the first tooth groove, and the shaft is fixed in the adjustment hole by the second tooth pattern. The complete engagement with the second tooth groove realizes the fixation of the rotating shaft in the socket, that is, the fixation of the rotating shaft in the rotating hole, and the swinging of the support rod in the swinging groove is limited by the fixation of the sleeve and the rotating shaft, so as to fix the support rod, that is, to achieve the limitation of the support rod, and then achieve the purpose of bracket adjustment, so as to realize the adaptation of the bracket to the user's arm so that the arm can be supported and supported by the bracket when it is raised to the highest point; in the above technology, each gear tooth of the first tooth pattern is opened along the axis direction of the sleeve, and each gear tooth of the second tooth pattern is opened along the axis direction of the rotating shaft, and the first tooth pattern is adapted to the first tooth groove and the second tooth pattern is adapted to the second tooth groove, so as to realize the fixation of the support rod after swinging.

[0009] The benefits of adopting the above technical solution are: in the above technology, when it is necessary to adjust the total length of the support rod to make the bracket fit the user's arm, the user or other operator unscrews the fixing screw so that the fixing screw no longer restricts the current matching hole. At this time, the upper rod can slide along the lower rod, that is, the end of the upper rod slides in the sliding hole, and when the bracket fits the user's arm, the upper rod is no longer slid. At this time, the through hole is aligned with one of the matching holes among the matching holes, and the user or other operator screws in the fixing screw so that the fixing screw is threadedly connected to the matching hole, thereby realizing the fixed connection between the upper rod and the lower rod, and then achieving the purpose of adjusting the total length of the support rod, thereby adapting to the situation where the lower bracket needs to fit the user's arm at different inclination angles, that is, the bracket always fits the user's arm under different degrees of recovery of the user.

[0010] The utility model is further configured that a universal ball head is connected between the bracket and the beginning of the upper rod.

[0011] The benefits of adopting the above technical solution are: the setting of the universal ball head in the above technology allows the bracket to autonomously follow the swinging or shaking of the patient's arm, thereby improving the comfort of the user during rehabilitation training, and the bracket always fits the user's arm at different inclination angles; the universal ball head in the above technology is existing technology, so its structure and function will not be described in detail; in the above technology, in order to facilitate the patient's need to swing his arms back and forth, a slider can be provided between the universal ball head and the bracket, and a sliding groove for the slider to slide is opened on the bottom wall of the bracket along the length direction of the bracket to meet the patient's need for horizontal sliding of the arm back and forth.
