[0002] Hand surgery refers to the surgery of the hands. Hands are used very frequently in human labor, so the chances of hand injuries and illnesses are also very high. When a person's hand is injured or ill, surgical treatment is often required. During the treatment and rehabilitation period, many patients will experience weakened hand strength and functional degeneration. At this time, hand exercisers are needed to exercise the patient's hands so that the patient's hands can gradually recover.
[0003] The publication number authorized by China is CN218944291U, and it is a patent for a hand rehabilitation exercise device. The device includes a main seat, a sub-seat is horizontally arranged on the upper part of the main seat, a movable cavity 2 is opened inside the sub-seat, a spring 2 and a stopper 2 are arranged in the movable cavity 2, two ends of the stopper 2 are respectively connected with the spring 2 and the pressure rod 3, a telescopic cavity 2 is opened in the pressure rod 3, a limit strip 2 and a pressure rod 4 are arranged in the telescopic cavity 2, a pressure block is arranged on the pressure rod 4, and two limit grooves are opened on the pressure rod 4. Through the establishment of the sub-seat, and the spring 2 and the stopper 2 are arranged in the movable cavity 2 opened inside the sub-seat, and the two ends of the stopper 2 are respectively connected with the spring 2 and the pressure rod 3, and the pressure rod 4 is arranged in the pressure rod 3, so that the patient's thumb can press the pressure block arranged on the pressure rod 4, so that the pressure rod 4 drives the pressure rod 3 and the stopper 2 to move in the movable cavity 2 for synchronous pressing exercise.
[0004] Although the above device can perform pressing exercises synchronously, there are still some problems when using the device:
[0005] 1. The device does not have a pulling mechanism and can only achieve finger exercise through active pressing by the patient.
