Description

Technical Field

[0001] This invention relates to the field of postoperative rehabilitation exercise technology, specifically to a functional exercise assessment device for breast cancer-affected limbs. Background Technology

[0002] Breast cancer, one of the most common malignant tumors in women, requires surgery to remove the breast and dissect the axillary lymph nodes. This process can easily damage nerves, blood vessels, and lymphatic vessels in the axillary area, leading to postoperative complications such as edema of the affected upper limb, limited shoulder joint movement, and decreased muscle strength, severely impacting patients' quality of life. To improve postoperative complications and promote functional recovery of the affected limb, rehabilitation therapy for breast cancer includes functional exercises for the affected limb. Targeted functional exercises can effectively increase shoulder joint range of motion, improve upper limb blood circulation, and reduce edema, thereby improving patients' self-care ability and quality of life. The exercise method relies on initial guidance from medical staff and subsequent self-directed practice by the patient. However, in practice, there is a lack of effective recording and assessment methods for the range of motion and number of repetitions, making it impossible to quantify and evaluate rehabilitation therapy due to varying individual compliance. On the one hand, the inability to accurately record the range of motion makes it difficult for patients to grasp the intensity and scale of the exercise. On the other hand, the lack of recording of the number of repetitions, an important indicator of exercise intensity, makes it impossible for medical staff to accurately understand patient compliance and exercise intensity. It cannot promote functional recovery during the patient's recovery phase, nor can it be used for exercise during the postoperative rehabilitation phase.

[0003] During surgery, mastectomy and axillary lymph node dissection inevitably damage the lymphatic vessels, blood vessels, and surrounding nerves and muscles in the axillary region, leading to temporary impairment of the lymphatic drainage system in the affected limb. Furthermore, the surgical incision is not yet fully healed, and the subcutaneous tissue is in the repair phase. The early postoperative period after breast cancer surgery is the first stage of wound healing and tissue repair. During this stage, patients need to perform elevation exercises on the affected limb, with necessary restrictions on the height of the raised arm. From a physiological perspective, premature or excessive elevation of the affected limb carries multiple risks. Traction on the unhealed surgical incision may lead to wound dehiscence, bleeding, or infection, prolonging the healing period. Clinical rehabilitation guidelines require strict control of the range of motion when raising the arm in the early postoperative period, generally limiting it to no more than chest or shoulder height, avoiding significant shoulder abduction and elevation, especially before the removal of the axillary drainage tube, where the height and intensity of arm elevation must be strictly limited. However, when patients exercise on their own, there is a lack of effective technical means to monitor and limit the height of their arms in real time. Relying solely on verbal guidance from medical staff is insufficient to ensure accurate execution. Some patients raise their arms too high for fear of recovery or dare not raise them due to fear of pain, all of which affect the quality of rehabilitation.

[0004] Therefore, in order to solve the problem of the inability to effectively record the range of motion and number of extensions during postoperative limb functional exercises for breast cancer patients, a device is developed that can record and evaluate limb exercise data, providing exercise guidance for patients and objective assessment basis for medical staff. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, the present invention provides a functional exercise assessment device for breast cancer-affected limbs.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: A functional exercise assessment device for breast cancer patients includes a fixation part, a following part, and a measurement part. The measurement part is located on one side of the fixation part, and the following part is located on the measurement part.

The push block abuts against the lower side of the value-collecting rack. A scale rod is fixedly connected to one side of the push block. A lower slider is connected to the other side of the push rod. A sliding helical gear is slidably connected inside the lower slider. A tension spring is fixedly connected between the sliding helical gear and the lower slider. The measuring unit also includes a value-marking component, which includes a lower frame. The fixed frame has a fixed lower frame with fixed helical teeth. The lower frame is marked with size markings. The marker rod cooperates with the size markings. A lower groove is opened on one side of the lower frame. The value-taking slider is slidably connected in the lower groove. Several fixed helical teeth are fixedly connected to the lower frame at the lower groove position. The fixed helical teeth array is in the lower groove of the lower frame. The upper side of the fixed helical teeth is inclined, and the lower side of the fixed helical teeth is flat. The upper side of the sliding helical teeth is flat, and the lower side of the sliding helical teeth is inclined. The sliding helical teeth cooperate with the fixed helical teeth.

[0011] Furthermore, the value rack is located on the side where the value gear moves downward when the pull rope is pulled away from the main shaft.

[0012] Furthermore, the fixed frame has a through groove on one side of the value-taking gear, and a value-taking connecting rod is fixedly connected to the side of the value-taking gear near the through groove. A value-taking slider is fixedly connected to the value-taking connecting rod, and the value-taking slider is slidably connected in the through groove. A connecting frame is fixedly connected between the push plate and the lower slider.

[0013] Furthermore, the data acquisition component includes a data acquisition gear, a finite movement rack component, a transmission component, and a counting component. The data acquisition gear is fixedly connected to the second end of the main shaft, and the finite movement rack component is meshed on the data acquisition gear. The limited movable rack component includes a counting rack, side teeth, a slide rod, and a vertical tension spring. The counting rack has side teeth on both sides, and the distance between the side teeth and the counting rack is one side tooth distance. The slide rod is fixedly connected to the side teeth near the counting rack, and the slide rod is slidably connected to the counting rack. A limit plate is fixedly connected to the end of the slide rod away from the side teeth. The counting rack has a stepped groove for the slide rod and the limit plate to cooperate. A vertical tension spring is fixedly connected between the limit plate and the counting rack. The transmission component includes a transmission rack, a transmission gear, and a ratchet. The rack is fixedly connected to the side away from the gear. The transmission gear is meshed with the rack. A ratchet is located in the middle of the transmission gear. A fixed rod is fixedly connected to the transmission gear. A gear shaft is fixedly connected to the fixed rod. A ratchet tooth is rotatably connected to the gear shaft. The ratchet tooth engages with the ratchet. A compression spring is fixedly connected between the ratchet tooth and the transmission gear. The counting component includes a fixed frame, an upper shaft, a digital dial wheel, a lower shaft, and a transmission dial wheel. The fixed frame is fixedly connected to a fixed frame. The upper shaft is fixedly connected to the fixed frame. The digital dial wheel is rotatably connected to the upper shaft. There are four digital dial wheels, each displaying a number from 0 to 9. The outer circumference of the digital dial wheel near the ratchet has a full-circumference dial pin array. Two transmission dial pins are fixedly connected to the side of the digital dial wheel away from the ratchet. The lower shaft is fixedly connected to the lower side of the fixed frame. The transmission dial wheel is rotatably connected to the lower shaft and is positioned between the two digital dial wheels. Long teeth are fixedly connected to the transmission dial wheel.

A long tooth on a transmission wheel engages with a transmission pin on a digital wheel near the ratchet, and a long tooth and a short tooth on a transmission wheel engage with a full-circumference pin on a digital wheel away from the ratchet. A connecting post is fixedly connected to the ratchet, and a digital dial on the side near the ratchet is fixedly connected to the connecting post.

[0014] Furthermore, a data retrieval connecting rod is fixedly connected to the data retrieval rack and the transmission rack, and a data retrieval slider is fixedly connected to the data retrieval connecting rod. A closed groove is opened on one side of the data retrieval rack on the fixed frame, and the data retrieval slider is slidably connected in the closed groove; the side teeth are slidably connected to the transmission rack and the data retrieval connecting rod.

[0015] Furthermore, the limited-movement rack component is located on the side where the data-taking gear moves downward when the pull rope is pulled away from the main shaft; the number of teeth of the data-taking rack corresponds to the variable of rotating the digital dial by one digit.

[0016] Furthermore, the ratchet rotates in the direction of increasing the number of the digital dial when pushed by the ratchet teeth.

[0017] The beneficial effects of this invention are: A functional exercise assessment device for breast cancer patients involves the patient wearing a fixation device with a fixation strap, engaging the hand of the affected limb with a pull ring, and performing extension exercises to restore the original function of the affected limb. During the exercise, the pull rope drives the main shaft to rotate. At this time, the main shaft drives the value rack to push the push block through the value gear. The push block drives the pointer to indicate the size mark reached by the extension, and at the same time drives the sliding helical teeth on the lower slider to move in cooperation with the fixed helical teeth. Through the limiting cooperation between the sliding helical teeth and the fixed helical teeth, the maximum extension value of the patient is retained, and the extreme value of the patient's extension is obtained. The main shaft engages with a data retrieval gear and a data retrieval rack. The data retrieval slider on the rack is limited by the enclosed space of the slot, restricting its movement. After pushing the rack to one end of the slot, the subsequent rotation of the gear only compresses the side teeth closer to the rack, ceasing engagement. When the gear reverses, it moves the side teeth, which pull the rack through a limit plate, allowing the gear to continue engaging. This ensures that regardless of the patient's recovery status, extension distance, or movement changes, the transmission rack moves the same distance in a single extension. When the pull rope follows the patient's extension, the transmission gear drives the ratchet to rotate via the ratchet. During the patient's repetitive retraction, the main shaft resets under the action of a spring, and the transmission gear rotates freely with the ratchet, allowing the ratchet to output a variable that only increases in the numerical direction to the digital dial. The digital dial increases progressively, acquiring the number of extensions the patient has made.

[0025] Example 5, as Figure 1 , 21 As shown in Figure 33 The fixing part includes a fixing body, which is attached to the body. The fixing body is open on the side away from the measuring part, and the two ends of the fixing body in the open position are detachably connected. Specifically, the fixation body is a strip structure, which is used to fix it to the patient's body. A fixation strap seat is fixedly connected to the first end of the fixation body, and the second end of the fixation body is wrapped around the fixation strap seat.

[0026] In summary, this invention provides a breast cancer limb functional exercise assessment device. When used, the patient wears the fixation body (1) via a fixation strap (101), and engages the hand of the affected limb with the pull ring (201) to perform extension exercises and restore the original function. During the exercise, the pull rope (2) drives the main shaft (303) to rotate. At this time, the main shaft (303) drives the value rack (311) to push the push block (314) via the value gear (310). The push block (314) simultaneously drives the marker (315) to indicate the size mark (306) reached by the extension, and simultaneously... The sliding helical tooth (318) on the movable slider (317) moves in conjunction with the fixed helical tooth (308). Through the limiting engagement of the sliding helical tooth (318) and the fixed helical tooth (308), the maximum value of the patient's extension is preserved, and the extreme value of the patient's extension is obtained. The main shaft (303) simultaneously engages with the data retrieval rack (321) through the data retrieval gear (320). The data retrieval slider (327) on the data retrieval rack (321) is limited in movement due to the closed space of the closed slot (302). The data retrieval gear (320) pushes the data retrieval rack (321) to the closed slot. After one end of the slot (302), the subsequent rotation of the counting gear (320) will only continuously compress the side teeth (322) closer to the counting rack (321), and no longer mesh with the counting rack (321). When the counting gear (320) reverses, the counting gear (320) pushes the side teeth (322), and the side teeth (322) pull the counting rack (321) through the limiting plate (3231), so that the counting gear (320) continues to mesh with the counting rack (321), so that no matter how the patient recovers, how far the extension distance is, or how the movement changes, it can be done in one movement. In the case of the extension, only the transmission rack (325) is driven to move the same distance. When the pull rope (2) follows the patient's extension, the transmission gear (328) pushes the ratchet (330) to rotate through the ratchet (331). When the patient's movement is repeated and reset, the main shaft (303) is reset under the action of the rotating spring (304). The transmission gear (328) carries the ratchet (331) to rotate freely, so that the ratchet (330) can output a variable that only increases in the direction of the number to the digital dial (342). The digital dial (342) increases step by step to obtain the number of extensions of the patient.
