Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a rehabilitation training device for postoperative functional exercise of the affected side of the breast cancer. BACKGROUND

[0002] In the postoperative rehabilitation treatment of breast cancer, the functional exercise of the affected side of the body is the core link for preventing postoperative complications (such as limited shoulder joint movement, muscle adhesion, and lymphedema) and promoting the recovery of limb function. Clinical practice shows that early postoperative rehabilitation training needs to strictly follow the principle of "progressive, from small to large", gradually transitioning from small joint activities such as hands and wrists to large joint movements such as elbows and shoulders, to avoid pulling the surgical incision due to early or excessive activity, affecting the healing effect.

[0003] At present, the commonly used postoperative rehabilitation training devices for breast cancer are mainly single-function, such as handgrip for hand strength training, and elastic band for upper limb stretching training, but such devices generally lack precise control of the training sequence and movement amplitude. In the early postoperative stage, if the patient directly performs elbow or shoulder movement without "warm-up" of the hands, it is easy to cause wound pulling due to insufficient muscle strength and poor joint flexibility, increasing the risk of pain and complications; the traditional device cannot automatically unlock the elbow movement permission according to the hand training intensity of the patient, and it is difficult to realize the step-by-step rehabilitation process of "hand training → elbow movement".

[0004] In addition, the existing fixed device lacks stability in fixing the upper arm and the lower arm, and relative displacement is easy to occur when the patient unconsciously moves, which not only affects the training effect, but also may cause secondary damage to the surgical site due to accidental bending of the joint. At the same time, most training devices lack feedback mechanisms for the patient's grip strength and movement degree, and cannot scientifically determine whether the patient has reached the "warm-up threshold" for elbow movement, making it difficult to ensure the safety and effectiveness of rehabilitation training.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0029] Reference Figures 1-7 The present embodiment provides a technical solution: a rehabilitation training device for postoperative limb function exercise of a breast cancer patient, which comprises a first fixed seat 100 for fixing an upper arm and a second fixed seat 110 for fixing a lower arm. The first fixed seat 100 is fixedly connected with a first hinged seat 340, and the second fixed seat 110 is fixedly connected with a second hinged seat 330 hinged with the first hinged seat 340. The second hinged seat 330 can be locked or unlocked to the first hinged seat 340, so that the first fixed seat 100 can be rotated or locked to the second fixed seat 110. The second fixed seat 110 is provided with a spherical air bag 200 at an end away from the first fixed seat 100. The patient grips the spherical air bag 200 to perform finger flexion and extension activities. The spherical air bag 200 provides resistance for finger gripping and auxiliary force for finger opening. When the gripping force and the gripping degree of the spherical air bag 200 increase, the second hinged seat 330 can be unlocked to the first hinged seat 340.

[0030] When the patient is doing rehabilitation training, first, the upper arm is fixed on the first fixing seat 100, and the lower arm is fixed on the second fixing seat 110, in the initial state, the first fixing seat 100 cannot swing relative to the second fixing seat 110, so as to ensure that the elbow part of the patient will not be bent to cause the traction of the wound, after the arm of the patient is fixed, the hand grips the spherical air bag 200 to exercise the finger part, so as to carry out the early postoperative rehabilitation training, with the training recovery of the patient and the gradual adaptation to the training state, the force of the hand gripping the spherical air bag 200 can be gradually increased, and when the force is increased to a suitable limit, the first hinge seat 340 and the second hinge seat 330 are unlocked, so that the elbow movement can be carried out, so that the patient starts to move from the hand, the movement range is from small to large, and the recovery effect after the operation is ensured through the above setting.

[0031] The arc-shaped strip 120 is rotationally connected to the first fixing seat 100 and the second fixing seat 110, one end of the arc-shaped strip 120 is clamped on the first fixing seat 100 or the second fixing seat 110 through a buckle, and the inner surface of the arc-shaped strip 120 is provided with an arc-shaped air bag 130, which can fix the arm on the first fixing seat 100 and the second fixing seat 110 after inflation.

[0034] After the arc-shaped strip 120 is fixed, the handle 180 on the straight piston rod 170 is manually pushed and pulled, so that the straight piston rod 170 reciprocally slides in the straight piston cylinder 140, so that the straight piston cylinder 140 sucks air through the suction pipe 160, and then injects the air into the arc-shaped air bag 130 through the exhaust pipe 150, so that the arc-shaped air bag 130 is inflated, and the arc-shaped air bag 130 is also provided with a deflation valve, which is opened after the activity is completed to deflate the arc-shaped air bag 130.

[0035] The spherical air bag 200 is communicated with a ventilation pipe 210, and the ventilation pipe 210 is communicated with the arc-shaped air bag 130 on the second fixing seat 110.
