Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation equipment technology, specifically relating to an extended-function hand exoskeleton. Background Technology

[0002] In recent years, the number of patients with hand motor dysfunction caused by accidents such as car crashes and workplace injuries, as well as neurological disorders such as stroke and spinal cord injury, has been increasing. The use of hand exoskeletons can help patients with rehabilitation or assist them in daily life. However, existing hand exoskeletons have the disadvantages of limited functionality and poor assistive capabilities. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes an extended-function hand exoskeleton. The concept involves fixing an extended end cap to the thumb end of an existing hand exoskeleton, and then removing auxiliary components from the extended end cap to assist the patient's rehabilitation and daily life.

[0004] An extended-function hand exoskeleton includes a hand exoskeleton body whose shape matches the contour of the palm. An extended end cap is connected to the end of the hand exoskeleton body near the thumb. The side away from the hand is defined as the outer side and the other side as the inner side. A rotating slot is provided on the outer side of the extended end cap. A rotating buckle is embedded in the rotating slot. The rotating buckle is provided with a mounting hole. An auxiliary accessory is inserted through the mounting hole.

[0005] Optionally, the accessory is a fork and spoon.

[0006] Optionally, the auxiliary accessory is a suction cup.

[0007] More specifically, the extended end cap is provided with screw holes, and the extended end cap is connected to the main body of the hand exoskeleton by screws passing through the screw holes.

[0008] The beneficial effects of this utility model are:

[0009] 1. An expandable end cap is used to enhance the assistive capabilities of the hand exoskeleton by installing corresponding accessories, thereby improving the patient's self-care ability in daily life.

[0010] 2. The accessories use a rotating buckle and rotating slot for easy installation, which is both convenient and secure.

[0011] 3. The extended end cap does not require major modifications to the hand exoskeleton; only corresponding functional extension accessories need to be added, resulting in low cost. Attached Figure Description

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
