Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an upper limb function rehabilitation device for breast cancer radiotherapy. Background Art

[0002] Breast cancer is a common malignant tumor in women, arising from the uncontrolled proliferation of mammary epithelial or ductal epithelial cells. The etiology and pathogenesis of breast cancer are relatively complex, mainly including: genetic factors, reproductive factors, sex hormones, lifestyle, etc. The treatment methods of breast cancer include surgical treatment, chemotherapy, endocrine therapy, targeted therapy, immunotherapy and radiotherapy, etc.

[0003] After surgical resection of breast cancer and adjuvant radiotherapy, the patient's upper limb activities are limited, resulting in a smaller range of upper limb abduction, which affects the subsequent continuous radiotherapy implementation plan and the control of breast cancer tumors. In addition, limited upper limb activities and long-term limited range of activities can easily cause skin tissue fibrosis, affecting the patient's normal movement after recovery;

[0004] Therefore, the present invention provides an upper limb functional rehabilitation device for breast cancer for radiotherapy to assist patients in upper limb exercise and ensure normal abduction of the upper limbs to avoid affecting subsequent radiotherapy treatment, and to exercise human tissue to avoid skin tissue fibrosis that affects the normal movement of the patient's upper limbs after surgery. Summary of the invention

[0005] In order to solve the drawbacks of the prior art, the present invention is achieved through the following technical solutions:

[0006] A breast cancer upper limb functional rehabilitation device for radiotherapy, comprising: a base, a driving disk, a motor, a controller, an electric push rod, a seat, and a connecting rod;

[0007] A gear column is arranged in the middle of the base, and an annular mounting groove is arranged on the outer periphery of the base to mount the drive disk; one side of the base can be detachably connected to the controller, and the other side has a mounting groove to mount the motor; a connecting column is arranged in the middle of the gear column to mount the seat, and a pedal is arranged at the lower part of the gear column;

[0008] The outer wall of the driving disk is provided with a gear connected to the motor, and an annular groove is provided on the driving disk; a gear 1 is provided within a range of 0°-180° on the outer wall of the annular groove, and a gear 2 is provided within a range of 180°-360° on the inner wall of the annular groove; gear shafts are symmetrically provided in the annular groove to respectively connect the gear 1 and the gear 2;

[0009] The upper part of the gear shaft is provided with a gear plate connected to the gear column, and the middle part of the gear shaft is provided with an electric push rod; the lower part of the electric push rod is sleeved with a connecting rod, and a handle is provided on the output shaft of the electric push rod; the other end of the connecting rod is rotatably connected to the connecting column;

[0010] Furthermore, a limiting groove is provided at the bottom of the annular groove to be slidably connected to the lower end of the electric push rod;

[0011] Furthermore, an arc-shaped block is provided at the lower end of the electric push rod for sliding connection with a limiting groove;

[0012] Furthermore, a straight rod is provided in the middle of the installation groove to install a motor; a driving gear is provided on the output shaft of the motor to connect the driving disk, and the driving gear is driven by the motor to drive the driving disk to rotate, and the driving disk drives gear 1 and gear 2 to drive the gear shafts on both sides to reverse synchronously, and drives the gear shafts on both sides to drive the electric push rod to approach or move away synchronously along the gear column; at the same time, during the reciprocating motion of the electric push rod approaching and moving away synchronously, the electric push rod drives the handle to reciprocate and extend;

[0013] Furthermore, the controller is a PLC controller, which is connected to the electric push rod and the motor circuit to control the operation of the motor and the electric push rod, and the extension distance and extension speed of the electric push rod are controlled by the controller;

[0014] The rotation speed of the motor is constant, and the forward and reverse rotation of the motor and the time of the forward and reverse rotation are controlled by a controller to adjust the rotation range of the electric push rod.

[0015] The beneficial effects of the present invention are:

[0016] The present invention discloses an upper limb functional rehabilitation device for breast cancer for radiotherapy, comprising: a base, a driving disk, a motor, a controller, an electric push rod, a seat, and a connecting rod. The patient sits on the seat, steps on a pedal, and holds handles on both sides with both hands. The motor and the electric push rod are controlled to work by the controller.

[0017] The motor drives the driving gear to drive the driving disk to rotate. The driving disk drives gear 1 and gear 2 to drive the gear shafts on both sides to reverse synchronously, driving the gear shafts on both sides to drive the electric push rods to move synchronously closer or farther along the gear column, driving the patient's upper limbs to perform outward expansion movements.

[0018] When the motor is working, the patient's upper limbs are moving back and forth, and at the same time, the electric push rod is working to drive the handle to move up and down, and drive the patient's upper limbs to swing up and down;

[0019] In the present invention, a controller is used to control the motor and the electric push rod to drive the patient's upper limbs to perform outward expansion movement and up and down swing, thereby solving the problem in the prior art that the patient's upper limb movement is limited, resulting in a small abduction range of the human upper limbs, affecting the subsequent continuous radiotherapy implementation plan and affecting the control of breast cancer tumors. In addition, the upper limb movement is limited, and the limited range of movement for a long time can easily cause skin tissue fibrosis, affecting the patient's normal movement after recovery.
