Description

TECHNICAL FIELD

[0001] The present application relates to a kind of postoperative rehabilitation auxiliary devices of vascular intervention. BACKGROUND

[0002] Vascular intervention, also known as endovascular intervention, is a technique that uses catheters, guide wires and other interventional devices to access the vascular system through a small incision in the skin to diagnose and treat diseased areas. Common vascular intervention procedures include vascular dilation, vascular stent implantation, intravascular thrombectomy and vascular embolization. Currently, after vascular intervention, patients need to exercise to recover faster and return to normal life and work.

[0003] For example, the Chinese patent with application number 202310444271.5 discloses a cardiovascular patient care and rehabilitation aid. When exercising, the patient's feet step down on the pedal to drive the first fixed rod to move downward along the limiting hole. At this time, the elastic band has a certain tension on the pedal, and the patient needs to exert force to pedal to resist the tension of the elastic band, achieving the exercise effect on the patient's lower limbs. After a period of exercise, the number of elastic bands can be increased according to the patient's physical condition to increase the tension of the elastic bands, achieving the effect of adjusting the tension training intensity according to the patient's different conditions, effectively improving the training effect and benefiting the patient's recovery.

[0038] The end of the seat plate 10 is provided with a placing plate 101, and two groups of guide columns 1011 are oppositely arranged at the end of the placing plate 101 away from the seat plate 10. The pedal plate 20 is slidingly arranged on the guide columns 1011 along the length direction of the placing plate 101. The resistance mechanism is connected with the pedal plate 20 and the seat plate 10, and is used to apply a pushing force to the pedal plate 20 to move close to the seat plate 10. The protection mechanism includes a pressing pad 30, a first spring 301, a locking rod 302 and a first transmission assembly. The pressing pad 30 is slidingly arranged at the top end of the pedal plate 20 along the thickness direction of the pedal plate 20. The first spring 301 is connected with the pressing pad 30 and the pedal plate 20, and is used to apply a pushing force to the pressing pad 30 to move away from the pedal plate 20. The locking rod 302 is slidingly arranged at the bottom end of the pedal plate 20 along the width direction of the pedal plate 20.
