Title:
KNEE EXOSKELETON DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/130968
Kind Code:
A1
Abstract:
A rotary motion generator (200) for helping a patient to relearn walking, includes a rotary shaft (204), a moveable lever (213), and a first elastomeric structure (201). The rotary shaft (204) is switchable between a one-way rotation mode and a two-way rotation mode in a sagittal plane, and locking the joint position by the one-way rotation mode. The moveable lever (213) protrudes from an outer periphery of the rotary shaft (204) perpendicularly for rotating the rotary shaft (204). The first elastomeric structure (201) is pneumatically controlled for engaging the moveable lever (213) for generating an output torque (302) and producing the relative rotatory movement of a lower arm (101) with respect to an upper arm (102). The rotary shaft (204) further comprises a pawl (208), a second elastomeric structure (209) for projecting or retracting the pawl (208), and a rotation locking mechanism (206) that switches the rotary shaft (204) between the one-way rotation mode and the two-way rotation mode.
