Description

Technical Field

[0001] The invention belongs to the technical field of exercise rehabilitation, and in particular relates to an exercise device for post-operative breast cancer patients. Background Art

[0002] Breast cancer is one of the most common malignant tumors in women worldwide, with an increasing incidence each year. It poses a serious threat to women's health and quality of life. Currently, treatment options for breast cancer include surgical resection, radiotherapy, chemotherapy, endocrine therapy, and targeted therapy. Surgery is a key treatment option for many patients with early-stage and some patients with advanced breast cancer.

[0003] Breast cancer surgery, especially radical surgery, typically requires partial or complete breast removal and may involve axillary lymph node dissection. This extensive surgical procedure inevitably damages the upper limb's lymphatic drainage system, nerves, and muscles, leading to a series of postoperative complications. Upper arm edema is a common problem that can severely impact patients' quality of life. Clinical statistics show that the incidence of upper limb lymphedema after breast cancer surgery is high, ranging from 15% to 30% at various times after surgery, with some patients experiencing it even years after surgery. Upper arm edema not only causes discomfort such as heaviness, pain, and numbness in the upper limb, but also limits range of motion, impacting patients' ability to carry out daily activities. Basic activities such as dressing, washing, and eating can become difficult. Furthermore, long-term edema can lead to serious consequences such as skin infections and fibrosis, further exacerbating the patient's pain and complicating recovery.

[0004] In order to better recover from upper arm edema, it is necessary to use exercise devices to assist in exercise recovery. Existing exercise devices use modules such as hand pressers, elastic pull rings, and three-dimensional wall climbing rulers to achieve upper limb exercise for patients undergoing breast cancer surgery. However, they lack a precise range of motion adjustment mechanism. The range of raising and lowering the patient's upper arm depends on the fixed structure of the device or the patient's own strength control. Due to the large differences in the physical conditions of patients after surgery, it is difficult to grasp the appropriate range of motion. If the range of motion is too small, the exercise effect is poor. If the range of motion is too large, it may over-stretch and damage the upper limb tissue, aggravating edema. In addition, some devices have violent movements, requiring rapid lifting and lowering or large rotation and swinging of the upper arm. This may have an exercise effect on healthy people, but for patients after breast cancer surgery, especially those with upper arm edema, violent movements will cause the upper limbs to bear greater impact force, which can easily cause wound rupture and bleeding, increase the risk of infection, interfere with lymphatic return, aggravate edema, and may also damage the axillary nerves and blood vessels, causing neurological symptoms, seriously affecting the quality of life.

[0005] Based on this, the present invention designs an exercise device for breast cancer patients after surgery to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems in the above-mentioned background technology and to propose an exercise device for breast cancer patients after surgery.

The buffer connection mechanism is installed on the side of the rotating shaft. The axis of the gear is fixedly connected to the end of the rotating shaft.

[0019] As a further description of the above technical solution:

[0020] The buffer connection mechanism includes an air cylinder, which is fixedly connected to the outside of the back plate, a sliding plate slidably connected inside the air cylinder, a vertical rod fixedly installed under the sliding plate, the vertical rod passes through and is slidably connected to the lower surface of the air cylinder, the bottom end of the vertical rod is fixedly connected to a connecting frame, and the bottom end of the connecting frame is fixedly connected to two sliding balls.

[0025] As a further description of the above technical solution:

[0026] The side of the extrusion plate is fixedly connected with an elastic component, and the elastic component is fixedly connected to the inner wall of the gas storage frame. The side of the gas storage frame is connected with an intermediate tube, and the other end of the intermediate tube is connected with the extension rod.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. The present invention utilizes a back plate, a seat plate, a supporting frame, a rotating shaft, a sliding connection frame, a sliding ball, a sliding plate, an air cylinder, a first air hole, and a second air hole, and utilizes a pneumatic damping system formed by the air cylinder, the first air hole, and the second air hole. When a patient performs an upper limb lifting exercise, the supporting frame converts rotation into compression and suction of the air in the air cylinder by the sliding plate through a transmission mechanism including the rotating shaft, the sliding connection frame, the sliding ball, and the vertical rod. Due to the physical restriction of the air hole on the gas flow rate, a stable and adjustable damping force is formed. This reaction force directly limits the movement speed of the sliding plate, thereby fundamentally controlling the rotational angular velocity of the rotating shaft and the supporting frame. The above-mentioned damping mechanism ensures that the supporting frame (and the patient's upper arm) cannot expand rapidly during the lifting process. It avoids traction damage to the surgical wound, lymphatic vessels and surrounding tissues caused by excessive movements. More importantly, when the patient relaxes due to muscle fatigue, the damping system can also effectively suppress the rapid fall of the arm under the action of gravity, eliminating the safety risks brought about by "sudden weightlessness" and providing full-process, two-way safety protection for the fragile upper limbs after surgery. This device puts safety first and guides patients to perform standard and effective rehabilitation exercises through a smooth and uniform movement pattern. This controlled movement not only helps patients gradually restore muscle strength and joint mobility, avoids ineffective training or negative effects caused by improper movements, but also enhances patients' confidence in rehabilitation training, improves rehabilitation experience, and ultimately achieves better treatment results.

[0029] 2. The present invention utilizes an airbag, a contact plate, an air storage frame, an intermediate tube, and an extension rod. When the patient places their upper arm in the support frame and adjusts to a comfortable position, their back naturally fits against the backboard. This action triggers the contact plate, which acts as an integrated sensing and transmission component. When slightly squeezed by the patient's back, the contact plate drives the squeezing plate to move synchronously via the crossbar. The displacement of the squeezing plate precisely delivers the preset gas in the air storage frame through the intermediate tube and the extension rod to the airbag. The airbag then expands until its surface fits tightly against the contours of the patient's upper arm. This process is automatically triggered by the patient's seating action. , without manual adjustment, it can achieve personalized adaptive wrapping according to the arm circumference and body shape of different patients. Through the above-mentioned pneumatic mechanism, the airbag can evenly and gently wrap and fix the patient's upper arm, effectively eliminating the problems of uneven pressure, excessive restraint or difficult to control tightness that may exist in traditional strap-type fixation. The stable fixation ensures that there is no relative sliding between the patient's upper limbs and the load-bearing frame during exercise, making the execution of rehabilitation movements more precise and standard, avoiding force errors or accidental strains caused by shaking or displacement, and providing reliable protection for safe and effective rehabilitation training.

[0030] 3. The present invention utilizes gears, a toothed plate, a movable frame, and massage wheels. When a patient performs an upper arm lift exercise, the rotation of the support frame is precisely converted into linear motion by a transmission mechanism consisting of a rotating shaft, gears, and toothed plate. This motion drives the massage wheels to provide a smooth, rhythmic rolling massage from bottom to top along both sides of the patient's spine. When the upper arm is lifted to its maximum height and begins to lower, the mechanism reverses its motion, and the massage wheels then roll along the original path from top to bottom. This design ensures that the back massage action is fully synchronized and coordinated with the upper limb movement throughout the entire "lift-and-lower" exercise cycle. Postoperative breast cancer patients often experience tension and soreness in their shoulder and back muscles due to surgical trauma, prolonged immobilization, or the exercise itself. The rolling massage applied synchronously during exercise by this device effectively promotes local blood circulation and relaxes tense shoulder and back muscles, particularly the trapezius and latissimus dorsi. This not only significantly improves exercise comfort and alleviates patients' fear of difficulty, but also helps prevent secondary pain caused by muscle stiffness, thereby encouraging patients to be more active and persistent in rehabilitation training.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] Please see the attached Figure 1 -Attached Figure 8 The present invention provides a technical solution: an exercise device for breast cancer patients after surgery, comprising a seat plate 1 and a back plate 10, the seat plate 1 and the back plate 10 being hingedly connected by a rotating connector 3, two sliding holes 4 being provided on the right side of the back plate 10, sliding grooves 5 being provided on the front and rear sides of the inner wall of the sliding hole 4, a movable massage component 6 being provided in the sliding groove 5, a rotating exercise mechanism 7 being connected to the outside of the movable massage component 6, the rotating exercise mechanism 7 being installed on the right side of the back plate 10, a buffer connection mechanism 8 being installed on the outside of the rotating exercise mechanism 7, the buffer connection mechanism 8 being fixedly installed on the right side of the back plate 10, a contact control mechanism 9 being installed on the right side of the back plate 10, the contact control mechanism 9 being connected to the rotating exercise mechanism 7.

[0043] Specifically, such as Figure 1-2 As shown, a seat cushion 2 is installed on the seat plate 1 , a notch is opened on the seat plate 1 for the rotation of the rotation exercise mechanism 7 , and the contact control mechanism 9 extends through the back plate 10 to the side of the back plate 10 close to the seat plate 1 .

[0044] The rotating connector 3 is used to conveniently control the rotation between the seat panel 1 and the back panel 10, and can control the folding and unfolding of the two. The rotating connector 3 can be rotated in multiple stages and fixed at a specified angle, and the seat panel 1 and the back panel 10 can be rotated to a preset seat angle, making it convenient for patients to sit comfortably on the seat panel 1 to perform exercise rehabilitation.

[0045] Specifically, such as Figure 3-4 and Figure 6 As shown, the mobile massage assembly 6 includes a gear 61, which is mounted on the side of the rotating exercise mechanism 7. A toothed plate 62 is meshed on the side of the gear 61, and a connecting rod 63 is fixedly connected to the side of the toothed plate 62. The end of the connecting rod 63 is fixedly connected to an intermediate rod 64, and three movable frames 65 are mounted on the side of the intermediate rod 64.

[0046] A massage wheel 66 is rotatably connected in the movable frame 65 , and sliding blocks 67 are fixedly connected to the front and rear sides of the movable frame 65 . The sliding blocks 67 are slidably connected in the sliding groove 5 , and the left side of the massage wheel 66 is located outside the sliding hole 4 .

[0047] The sliding block 67 and the sliding groove 5 guide and limit the vertical movement of the movable frame 65 and the massage wheel 66 to ensure the stable movement of the massage wheel 66. The gear 61 controls the upward movement of the movable frame 65 and the massage wheel 66 through the gear rod, the connecting rod 63 and the intermediate rod 64. The massage wheel 66 rolls upward along the patient's back to achieve a massage action.

[0048] Specifically, such as Figure 3-5 As shown, the rotation exercise mechanism 7 includes a supporting frame 71, which is used to support the patient's upper limbs. Two air bags 72 are installed in the supporting frame 71. An extension rod 73 is fixedly connected to the right side of the supporting frame 71. A rotating shaft 74 is installed outside the extension rod 73, and a bearing 75 is provided on the outer cover of the rotating shaft 74.

[0049] A fixing rod 76 is fixedly connected to the side of the bearing 75, and the fixing rod 76 is fixedly connected to the right side of the back plate 10. The buffer connection mechanism 8 is installed on the side of the rotating shaft 74. The axis of the gear 61 is fixedly connected to the end of the rotating shaft 74. The extension rod 73 is hollow, and the extension rod 73 is connected to the airbag 72, and the extension rod 73 is connected to the contact control mechanism 9.

[0050] The supporting frame 71, the extension rod 73 and the rotating shaft 74 can rotate in the bearing 75, so as to facilitate the rotation of the patient's upper arm in the supporting frame 71. The patient's upper arm is placed on the supporting frame 71 for lifting exercise, and the supporting frame 71, the extension rod 73 and the rotating shaft 74 rotate. During the rotation of the rotating shaft 74, the vertical rod 83 and the sliding plate 82 are controlled to move upward by the sliding connecting frame 88 and the sliding ball 87.

[0051] Specifically, such as Figure 3-4 and Figure 7 As shown, the buffer connection mechanism 8 includes an air cylinder 81, which is fixedly connected to the outside of the back plate 10, and a sliding plate 82 is slidably connected inside the air cylinder 81. A vertical rod 83 is fixedly installed under the sliding plate 82, and the vertical rod 83 passes through and is slidably connected to the lower surface of the air cylinder 81. The bottom end of the vertical rod 83 is fixedly connected to a connecting frame 86, and the bottom end of the connecting frame 86 is fixedly connected to two sliding balls 87.

[0052] The sliding ball 87 is slidably connected to a sliding connection frame 88 . The sliding connection frame 88 is fixedly connected to the side of the rotating shaft 74 . A first air hole 84 is opened below the air cylinder 81 , and a second air hole 85 is opened on the air cylinder 81 .

[0053] The sliding ball 87 slides in the sliding connection frame 88, and can ensure that the sliding connection frame 88 maintains connection with the sliding ball 87 while rotating. During the rotation of the rotating shaft 74, the vertical rod 83 and the sliding plate 82 are controlled to move upward by the sliding connection frame 88 and the sliding ball 87. The sliding plate 82 squeezes and discharges the gas in the gas cylinder 81 through the second air hole 85, and sucks the external gas into the gas cylinder 81 through the first air hole 84. Since the speed of the gas passing through the first air hole 84 and the second air hole 85 is limited, the moving speed of the sliding plate 82 is limited, thereby avoiding the rotating shaft 74 and the supporting frame 71 from rotating too fast.

[0054] Specifically, such as Figure 1-4 and Figure 8 As shown, the contact control mechanism 9 includes an air storage frame 91, two side plates 92 are fixedly connected to the outside of the air storage frame 91, the side plates 92 are fixedly connected to the side of the back plate 10, an extrusion plate 93 is slidably connected to the inside of the air storage frame 91, a cross bar 94 is fixedly connected to the side of the extrusion plate 93, the cross bar 94 passes through and is slidably connected to the side of the air frame, and a contact plate 95 is fixedly connected to one end of the cross bar 94 located outside the air storage frame 91.

[0055] The side of the extrusion plate 93 is fixedly connected to an elastic component 96 , which is fixedly connected to the inner wall of the gas storage frame 91 . The side of the gas storage frame 91 is connected to an intermediate tube 97 , and the other end of the intermediate tube 97 is connected to the extension rod 73 .

[0056] The back is attached to the backboard 10, and the contact plate 95 is squeezed and moved. At the same time, the contact plate 95 drives the cross bar 94 and the squeezing plate 93 to move. When the squeezing plate 93 moves, the gas in the gas storage frame 91 is squeezed out, and the gas enters the airbag 72 through the middle tube 97 and the extension rod 73. The airbag 72 expands and fits the surface of the patient's upper limb.

[0057] Working principle, when using:

[0058] By rotating the connecting piece 3, the seat plate 1 and the back plate 10 are rotated to a preset seat angle. The patient who needs to perform postoperative exercises sits on the seat plate 1 and places the upper arm part in the bearing frame 71. Then the position is adjusted so that the back fits on the back plate 10. The contact plate 95 is squeezed and moved. At the same time, the contact plate 95 drives the cross bar 94 and the squeezing plate 93 to move. When the squeezing plate 93 moves, the gas in the gas storage frame 91 is squeezed out. The gas enters the air bag 72 through the intermediate tube 97 and the extension rod 73. The air bag 72 expands and fits the surface of the patient's upper limb.

[0059] Then the patient's upper limb is lifted for exercise, and the supporting frame 71, the extension rod 73 and the rotating shaft 74 are rotated. During the rotation of the rotating shaft 74, the vertical rod 83 and the sliding plate 82 are controlled to move upward by the sliding connecting frame 88 and the sliding ball 87. The sliding plate 82 squeezes the gas in the air cylinder 81 out through the second air hole 85 and sucks the external air into the air cylinder 81 through the first air hole 84. Since the speed of the gas passing through the first air hole 84 and the second air hole 85 is limited, the moving speed of the sliding plate 82 is limited, so as to avoid the rotating shaft 74 and the supporting frame 71 from rotating too fast, thereby ensuring that the supporting frame 71 and the patient's upper arm will not be quickly opened, and the arm will not fall down quickly due to weakness. While ensuring the exercise effect, it will not cause injury to the patient.

[0060] During the rotation of the rotating shaft 74, the gear 61 is controlled to rotate. The gear 61 controls the movable frame 65 and the massage wheel 66 to move upward through the gear rod, the connecting rod 63 and the intermediate rod 64. The massage wheel 66 rolls upward along the patient's back to achieve a massage action until the upper arm is raised to the maximum height. Then the patient's upper arm controls the supporting frame 71 to rotate downward, the sliding plate 82 moves downward in the air cylinder 81, and the massage wheel 66 rolls downward on the patient's back. Then the above exercise process is repeated continuously to complete the exercise and massage process safely.

[0061] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
