Patent number: 10864091Abstract: A prosthetic knee having a passive knee locking mechanism that uses the same four-bar mechanics found in a natural knee. The flexible four-bar mechanism guides the motion of the knee, aids in the return of the knee from full flexion to extension, and connects a femoral gear to a tibial gear. The gears have a circular radius and are connected using parallel links to keep the femur and tibia together when the knee is active. The knee stays locked throughout the stance phase. At toe off, no weight is applied on the prosthetic knee allowing the knee to flex. The flexible links are stretched, thereby increasing the stiffness in the springs, and at terminal swing phase, moments before heel strike, the flexible links in the four-bar mechanism snap back to the extended/locking position and lockout once the user applies his/her weight on the knee.Type: GrantFiled: May 2, 2019Date of Patent: December 15, 2020Assignee: University of South FloridaInventors: Tyagi Ramakrishnan, Kyle B.

Patent number: 10702402Abstract: A passive knee locking mechanism using the position of the shank and the weight of the user to lock. The mechanism has translational motion, which allows the shank to move linearly along the sagittal/vertical plane, which locks and unlocks the knee, and rotational motion for the shank to swing when unlocked. The knee block, which is disposed at the top of the shank, has a spur gear that locks with a matching gear rack on the top plate of the knee housing. The side plates for the knee housing have a linear path that makes for the translational motion. During heel strike, the stopper in the front plate of the knee housing positions the shank in a straight position. When the user applies their weight for initiating stance phase, the knee block traverses up the path and the spur gear meshes with the matching rack, locking the knee.Type: GrantFiled: August 2, 2018Date of Patent: July 7, 2020Assignee: University of South FloridaInventors: Tyagi Ramakrishnan, Kyle B.

Patent number: 10292889Abstract: A compliant bimanual rehabilitation system. The device allows for the user or operator's hands to be coupled with a variety of coupling stiffnesses and in a variety of symmetry modes, leading to enhanced rehabilitation of the impaired arm. Structurally, the device includes a carrier assembly slidably coupled to a base along a y-axis, an upper assembly rotatably coupled to the carrier assembly along a z-axis, handle slides slidably coupled to the upper assembly along an x-axis, compliant handle assemblies coupled to the handle slides, and handles coupled to the compliant handle assemblies. Encoders and load cells can also be positioned accordingly to monitor the position of the components and force applied to the device. Spring stacks can be coupled to the compliant handle assemblies to adjust coupling stiffnesses. The handles are indirectly linked to each other to facilitate rehabilitation of the paretic arm using the sound arm.Type: GrantFiled: November 18, 2015Date of Patent: May 21, 2019Assignee: University of South FloridaInventors: Samuel Houston Lawrence McAmis, Kyle B.
