Description

Technical Field

[0001] This invention relates to the field of postoperative rehabilitation assistive equipment technology, and in particular to a rehabilitation training device for reverse shoulder joint replacement surgery. Background Technology

[0002] Reverse shoulder arthroplasty is an important treatment for end-stage shoulder diseases such as severe rotator cuff tears, shoulder osteoarthritis, and traumatic arthritis, especially suitable for elderly patients or cases that have not responded to conservative treatment. This surgery reverses the articular surface structure of the humeral head and glenoid fossa, using the deltoid muscle to replace the function of the damaged rotator cuff, thereby restoring the range of motion and stability of the shoulder joint. Since postoperative rehabilitation directly determines the surgical outcome, clinical practice requires phased range of motion training, muscle strength training, and functional coordination training within a safe range to avoid complications and restore patients' daily living abilities such as dressing, combing hair, and lifting objects. Therefore, specialized training devices adapted to postoperative rehabilitation needs are urgently needed. Current postoperative rehabilitation mainly relies on two methods: Firstly, traditional rehabilitation requires manual assistance from professional therapists, which not only heavily depends on the therapists' experience and skills, resulting in high labor costs and limited service coverage, but also makes it difficult for patients to conduct training independently at home, failing to meet the clinically recommended daily training frequency. Secondly, existing rehabilitation machines mostly require patients to train in a sitting or standing position, which is not suitable for use in bed. Patients who have undergone reverse shoulder replacement surgery, especially elderly patients or those with weaker underlying conditions, are particularly vulnerable in the early postoperative period due to weakness and limited mobility. Maintaining a sitting or standing position for extended periods can easily lead to fatigue, dizziness, and other discomfort, and even increase the risk of falls.

[0003] Therefore, a rehabilitation training device for reverse shoulder joint replacement surgery was designed. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a rehabilitation training device for patients after reverse shoulder joint replacement surgery.

They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] Example 1: Please see Figures 1-10A rehabilitation training device for reverse shoulder arthroplasty includes a mounting base 1 for providing basic support, an adjustment plate 2 slidably mounted along the top length of the mounting base 1, a main rod 3 rotatably mounted around an axis perpendicular to the top surface of the adjustment plate 2 for driving the patient's upper limb to achieve shoulder abduction, flexion and rotation, and a fixing component 4 detachably snapped onto the outer wall of the main rod 3 for stabilizing and fixing the patient's upper arm; the mounting base 1, adjustment plate 2, main rod 3 and fixing component 4 work together to achieve position adjustment and movement drive for the rehabilitation training of the patient's upper limb.

[0026] The mounting base 1 has an overall U-shaped groove design. The bottom of the mounting base 1 is threaded with a clamping column 11 for fixing the device. The top of the clamping column 11 is fixed with an anti-slip rubber pad 111, and the bottom is equipped with a hexagonal adjustment knob 112. By rotating the clamping column 11, the mounting base 1 can be firmly clamped to the support surface such as the edge of the bed or rehabilitation training table to prevent the device from shifting during training.

[0027] The top of the mounting base 1 is recessed downward along the length direction to form a sliding groove. On the inner walls of both sides of the sliding groove, there are integrally formed convex rails 13 extending along the length direction. The cross-section of the convex rail 13 is T-shaped, and the outer wall of the convex rail 13 is provided with a wear-resistant coating, which can reduce friction loss when sliding with the adjustment plate 2 and extend the service life of the device.

[0028] The two side walls of the adjustment plate 2 are respectively provided with T-shaped grooves that are adapted to the corresponding convex rails 13. The adjustment plate 2 is slidably connected to the corresponding convex rails 13 through the T-shaped grooves, and the adjustment plate 2 can slide back and forth along the convex rails 13 to adjust the lateral position. A turntable 21 is rotatably installed at the top center of the adjustment plate 2 through a bearing. The turntable 21 can rotate around the bearing axis to adapt to different training direction requirements.

[0029] The circumferential edge of the turntable 21, the top circumferential of the adjusting plate 2, and the top sliding groove of the mounting base 1 are each provided with the same number of limiting holes 12. A pin 5 can be inserted into the limiting hole 12. The pin 5 passes through the limiting hole 12 of the turntable 21, the adjusting plate 2, and the mounting base 1 to achieve relative fixation of the three, thereby limiting the rotation angle of the turntable 21.

[0030] A fixed plate 211 for support is fixedly installed on one side of the top of the adjusting plate 2, and a controller 22 for controlling the motor 23 is fixedly installed on the other side of the top. The motor 23 is fixedly embedded inside the controller 22. The output shaft of the motor 23 passes through the bottom of the main rod 3 in a horizontal direction and is fixed to the main rod 3. The end of the output shaft of the motor 23 away from the main rod 3 passes through the fixed plate 211 and is rotatably connected to the fixed plate 211 through a bearing. The controller 22 is provided with a display screen and adjustment buttons, which can set the rotation speed of the motor 23.

[0031] The outer wall of the main rod 3 has a rectangular groove 31 along its length. The inner wall of the groove 31 has symmetrical scale lines on both sides. The auxiliary rod 32 is slidably embedded in the groove 31. The outer wall of the auxiliary rod 32 is clearance-fitted with the inner wall of the groove 31. The side wall of the main rod 3 is threaded with a positioning bolt. The end of the positioning bolt passes through the side wall of the main rod 3 and abuts against the outer wall of the auxiliary rod 32. The position of the auxiliary rod 32 in the groove 31 is fixed by tightening the positioning bolt to adapt to the upper arm length of different patients.

[0032] The fixation component 4 is provided in at least two sets. The two sets of fixation components 4 are detachably snapped onto the upper middle part of the main rod 3 and the upper middle part of the auxiliary rod 32, respectively. The fixation component 4 on the main rod 3 is adapted to the patient's upper arm near the shoulder joint, and the fixation component 4 on the auxiliary rod 32 is adapted to the patient's forearm near the elbow joint. The distance between the two sets of fixation components 4 can be adjusted synchronously with the sliding of the auxiliary rod 32 to ensure multi-point stable fixation of the patient's upper limb.

[0033] The fixing component 4 includes a snap-fit ​​buckle 41 for snapping onto the outer wall of the main rod 3 and the auxiliary rod 32, an arc-shaped plate 42 fixedly connected to the outer wall of the snap-fit ​​41, and Velcro 43 fixedly disposed at both ends of the arc-shaped plate 42. The opening of the snap-fit ​​41 is connected by a spring hinge, which can be opened and closed elastically to achieve quick snap-fit ​​and disassembly. The inner wall of the arc-shaped plate 42 is fitted with a medical sponge pad. The Velcro 43 includes a hook side and a rough side. The tightness of the wrap can be adjusted by the adhesion of the Velcro 43 to avoid compressing the blood vessels of the patient's limb.

[0034] The top of the auxiliary rod 32 is slidably mounted with a grip bar 33. The top of the grip bar 33 is bent away from the main rod 3. A rubber pad 331 is fixedly fitted on the outer wall of the bend. The surface of the rubber pad 331 is provided with a diamond-shaped anti-slip texture to facilitate the patient's grip.

[0035] The mounting base 1 adopts a C-shaped groove design, which can be fixed to the support surface such as the edge of the bed, the back of the rehabilitation training table or the bench. By rotating the adjustment knob 112, the clamping column 11 is moved, so that the anti-slip rubber pad 111 fits against the bottom of the bed board, effectively preventing the device from shifting due to the patient's movements during training. The sliding groove formed by the downward indentation of the top of the mounting base 1 along the length direction and the integrally formed convex rails 13 on both sides of the inner wall, the convex rails 13 have a T-shaped cross section and a wear-resistant coating on the outer wall, which not only provide guidance for the sliding of the adjustment plate 2; The T-shaped grooves on both sides of the adjustment plate 2, which are adapted to the convex rail 13, allow the adjustment plate 2 to be easily adjusted to the lateral position according to the patient's shoulder width, ensuring that the main rod 3 is directly facing the patient's shoulder joint and providing an accurate positional basis for subsequent rehabilitation training. The turntable 21, which is mounted on the top center of the adjustment plate 2 via a bearing, can rotate freely around the bearing axis and can adapt to different training direction requirements. Whether it is shoulder abduction or flexion training, it can be easily achieved by rotating the turntable 21. The turntable 21, the adjustment plate 2, and the mounting base 1 have the same number of limiting holes 12 and insertable pins 5, which achieve relative fixation of the three. By passing the pins 5 through the corresponding limiting holes 12, the personalized rehabilitation training needs of different patients can be met. The rectangular groove 31 along the length of the outer wall of the main rod 3 and the symmetrical scale lines on both sides of the inner wall provide a precise reference for the sliding of the auxiliary rod 32. The auxiliary rod 32 is slidably fitted into the groove 31, with a clearance fit between the outer wall and the inner wall of the groove 31. By observing the scale lines, the auxiliary rod 32 can be slid to a position suitable for the patient's upper arm length, from the shoulder joint to the elbow joint. The positioning bolts threaded on the side wall of the main rod 3, when tightened, can tightly abut against the outer wall of the auxiliary rod 32, fixing the position of the auxiliary rod 32 in the groove 31. This ensures that the auxiliary rod 32 will not wobble during training, thus adapting to the differences in upper arm length among different patients and providing rehabilitation training that is more tailored to their individual circumstances. At the same time, two sets of detachable snap-fit ​​installations are also included. The fixing components 4 in the upper part of the main rod 3 and the upper part of the secondary rod 32 can respectively fit the patient's upper arm near the shoulder joint and the forearm near the elbow joint. The distance between the two sets of fixing components 4 can be adjusted synchronously with the sliding of the secondary rod 32, ensuring multi-point stable fixation of the patient's upper limb. The snap-type buckle 41 in the fixing component 4 is connected by a spring hinge, which can be opened and closed elastically, realizing quick snap-on and disassembly, which is convenient for medical staff to operate. The medical sponge pad attached to the inner wall of the arc plate 42 can increase the comfort of the patient's limb in contact with the fixing component 4. The Velcro 43 at both ends of the arc plate 42 includes a hook side and a rough side. The tightness of the wrap can be flexibly adjusted by adhesion to avoid compressing the blood vessels of the patient's limb, providing the patient with a safer and more comfortable fixation method. The controller 22, fixedly installed on one side of the top of the adjustment plate 2, contains a motor 23 that provides power support for rehabilitation training. The display screen and adjustment buttons on the surface of the controller 22 are simple and convenient to operate. Medical staff can easily set the rotation speed of the motor 23 according to the patient's rehabilitation stage. For example, a low speed can be set in the early postoperative period to avoid excessive traction and secondary injury to the patient. The display screen can also display the set parameters simultaneously, making it convenient for medical staff to monitor the training in real time. The grip bar 33, which is slidably installed on the top of the auxiliary bar 32, bends away from the main bar 3. This design is ergonomic and makes it easy for the patient to hold the grip naturally. The rubber pad 331 fixedly fitted on the outer wall of the bend has a diamond-shaped anti-slip texture, which further increases the friction between the patient's hand and the grip bar 33, ensuring that the patient can hold the grip stably during training and can concentrate more on rehabilitation training, thereby improving the training effect. Through the sliding connection design between the grip bar 33 and the auxiliary bar 32, when the patient performs rehabilitation training, the main bar 3 rotates along the axis of the output shaft of the motor 23 under the drive of the motor 23. At this time, the patient holds the grip bar 33 in a relatively fixed position. As the rotation of the main bar 3 drives the auxiliary bar 32 to rotate, the rotation trajectory of the auxiliary bar 32 will change with the rotation of the main bar 3, which will cause the relative angle between the grip bar 33 and the patient's hand to change continuously. In order for the patient to complete the training movements comfortably and effectively, the grip bar 33 needs to adaptively adjust according to the rotation trajectory of the auxiliary bar 32. Through the sliding connection with the auxiliary bar 32, it is ensured that the grip bar 33 is always in a position suitable for the patient to hold and exert force, thereby improving the training effect and the patient's user experience.

[0036] During operation, first align the I-shaped groove of the mounting base 1 with the edge of the bed, rotate the hexagonal adjustment knob 112 at the bottom of the mounting base 1 to move the clamping column 11 upward until the anti-slip rubber pad 111 at the top of the clamping column 11 is tightly attached to the bottom of the bed board, and the device is firmly clamped to the edge of the bed to prevent the device from shifting during training. Push the adjustment plate 2 so that it slides back and forth along the T-shaped convex rail 13 in the sliding groove of the mounting base 1 through the T-shaped grooves on both sides, and adjust it to a suitable lateral position according to the patient's shoulder width to ensure that the main rod 3 is directly facing the patient's shoulder joint; After determining the shoulder joint training direction of abduction or flexion by rotating the turntable 21 on the top of the adjustment plate 2, insert the pin 5 into the corresponding limiting holes 12 of the turntable 21, adjustment plate 2, and mounting base 1 to fix the three relatively and limit the rotation angle of the turntable 21. Observe the scale line on the inner wall of the slide groove 31 of the main rod 3, slide the auxiliary rod 32 along the slide groove 31, so that the extension length of the auxiliary rod 32 is adapted to the length of the patient's upper arm from the shoulder joint to the elbow joint, and then tighten the positioning bolt on the side wall of the main rod 3 so that its end is pressed against the outer wall of the auxiliary rod 32 to fix the position of the auxiliary rod 32. The grip bar 33 at the top of the sliding auxiliary bar 32 allows the patient's hand to naturally grip the bend of the grip bar 33, and the diamond-shaped anti-slip rubber pad 331 on the outer wall of the grip bar 33 ensures a stable grip. Install fixing component 4: The two sets of fixing components 4 are respectively snapped into the upper part of the main rod 3 corresponding to the end of the patient's upper arm near the shoulder joint and the upper part of the auxiliary rod 32 corresponding to the end of the patient's forearm near the elbow joint by the elastic opening and closing of the spring hinge at the opening of the buckle 41 of the fixing component 4. The patient's upper arm and forearm are respectively attached to the inner wall of the arc-shaped plate 42 of the two sets of fixation components 4. The tightness of the wrapping is adjusted by the hook and loop surfaces of the Velcro 43 at both ends of the arc-shaped plate 42 to ensure that the limb is firmly fixed and does not compress blood vessels. Operate the adjustment buttons on the surface of the controller 22 on the top of the adjustment plate 2, and set the rotation speed of the motor 23 according to the patient's recovery stage. For example, set it to low speed in the early postoperative period to avoid excessive traction. The setting parameters are displayed on the display screen of the controller 22. When the controller 22 is activated, the output shaft of the motor 23 drives the main rod 3 to rotate around the horizontal axis, thereby enabling the patient's upper limb to perform shoulder abduction or flexion training.
