Description

Technical Field

[0001] The present invention relates to the technical field of hand rehabilitation robots, and in particular to a hand rehabilitation robot that prevents crushing injuries and an operating method thereof. Background Art

[0002] At present, there is a lack of rehabilitation equipment for patients with hand dysfunction caused by stroke in the market. About 75% of stroke patients will have sequelae of varying degrees after the onset of the disease. Among the many sequelae, hemiplegia has the highest incidence rate. In the rehabilitation of hemiplegia, the rehabilitation of hand function is the most difficult. Clinically, the hand is fixed in a fixed position, which often causes congestion around the tendons in the joints to form fibrous degeneration. The hand rehabilitation robot is a wearable device that helps patients with rehabilitation training. In order to improve the training efficiency of patients with hand dysfunction, a hand rehabilitation robot is needed, but the existing hand rehabilitation robots still have the following shortcomings:

[0003] For example, the invention with publication number CN218572493U discloses a hand function rehabilitation robot, which can realize intelligent control, realize matching training software to train fingers, and realize various training methods such as individual movement of the patient's five fingers, movement of all fingers, movement of separate fingers, mirror movement, etc., and can accurately obtain the patient's intentional movement signal, display movement information, angle, strength and other information through the screen, and can summarize the patient's rehabilitation data and generate an evaluation report. However, similar to the comparative documents of the above-mentioned application, when the hand rehabilitation robot is used, since most hand rehabilitation robots cannot adapt to the size of the hand rehabilitation robot according to the size of the user's fingers, the hand rehabilitation robot is easy to crush the patient's hand when driving the patient's fingers to exercise, resulting in the problem of reduced practicality and reduced use efficiency of the hand rehabilitation robot.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a hand rehabilitation robot for preventing crushing and an operation method thereof are proposed. Summary of the invention

[0011] Furthermore, the inner dimension of the installation slot is matched with the outer dimension of the installation slide block, and the installation slide block is slidably connected to the fixed block via the installation slot.

[0012] Furthermore, the clamping ring is embedded with the limiting ring, and the clamping ring is elastically connected to the limiting ring via a spring damping rod.

[0013] Furthermore, the number of the clamping rings is two, and the two clamping rings are symmetrically arranged on both sides of the interior of the limiting ring with respect to the front center axis of the limiting ring.

[0014] Furthermore, an operating method of a hand rehabilitation robot that prevents crushing injuries is applied to the hand rehabilitation robot that prevents crushing injuries, and its operating method is as follows: first, the use of the hand rehabilitation robot is adjusted through the control panel arranged on the upper end of the main frame, and the first wearing strap is fixedly installed on the left side of the outside of the main frame through the mounting block, and the Velcro fur surface is installed above the front end of the first wearing strap.
