Description

A double-rotary block type postoperative rehabilitation training device for breast cancer and its application method

technical field

The invention relates to a double-rotating block postoperative rehabilitation training device for breast cancer and a use method thereof, belonging to the field of postoperative rehabilitation devices for breast cancer.

Background technique

Breast cancer is one of the most common malignant tumors in women, and its incidence rate ranks first in women's cancer diseases, causing great harm to women's physical and mental health. Surgery is the main method to cure breast cancer, but complications such as upper limb lymphedema and shoulder joint dysfunction often occur after surgery. Comprehensive postoperative rehabilitation training for patients with breast cancer can help restore the function and appearance of the breast, improve the limb function of patients, and improve the quality of life after surgery.

The current postoperative rehabilitation training for breast cancer is mainly divided into manual exercise and equipment exercise. Unarmed exercises are carried out under the guidance of medical staff, starting from the wrist joint to the elbow joint and shoulder joint. The purpose of manual exercise is not clear, there is blindness, and the patient is inert after the operation, and the exercise is not active. After the scar contracture, the patient will have various complications, and the rehabilitation process needs the guidance of medical staff throughout the process, which wastes medical resources; in addition, the utility model CN206792939U Postoperative recovery wall climber for breast cancer is a common apparatus exercise method, and the affected limb raises the arm by climbing the wall climber, and its movement mode is single, and the arm can only move straight up and down, and cannot carry out all-round rehabilitation training, and There is no buffer in the lifting process, which is easy to cause secondary injuries. The elliptical motion mechanism disclosed in CN103801990B can realize the elliptical motion track, but the radius of the ellipse needs to be adjusted by the operator and cannot be adjusted by itself, and the line connecting the two foci of the ellipse has only two forms, vertical and horizontal, and cannot realize the rotation of the elliptical track.

To sum up, the existing rehabilitation methods after breast cancer surgery have technical problems and deficiencies such as tight medical resources, high patient inertia, ineffective rehabilitation, single rehabilitation exercise, and easy to cause secondary injuries.
