4 results about "Radial deviation" patented technology

The application provides a kind of based on the tension whole wrist exoskeleton of cable drive, including battery pack and drive unit, first support exoskeleton is adapted to patient's forearm by wearing;Second support exoskeleton is adapted to patient's palm by wearing;Flexion and extension tensioning piece and ulnar and radial tensioning piece are sequentially threaded through first support exoskeleton and second support exoskeleton, when flexion part extends from first direction to flexion and extension drive part, extension part extends along second direction opposite to first direction, when ulnar deviation part extends from third direction to ulnar and radial drive part, radial deviation part extends along fourth direction opposite to third direction, flexion part, extension part, ulnar deviation part and radial deviation part are respectively matched with first support exoskeleton and second support exoskeleton to provide at least four direction degrees of freedom of wrist joint movement.The application can realize that patient wears conveniently and provides multiple degrees of freedom for wrist joint movement, and then improves the treatment effect of patient rehabilitation training.

The invention discloses a humanoid mechanical arm wrist and a humanoid mechanical arm, and relates to the technical field of humanoid mechanical arms, the humanoid mechanical arm wrist comprises a forearm, a wrist, a back stretching and buckling driving assembly and an ulnar deflection and radial deflection driving assembly; the back stretching and buckling driving assembly and the ulnar deflection and radial deflection driving assembly are arranged between the forearm and the wrist side by side and are both in transmission connection with the forearm and the wrist; the ulnar deflection radial deflection driving assembly and the wrist form rotary connection rotating around a first axis, and the ulnar deflection radial deflection driving assembly can drive the wrist to rotate around a second axis; the back stretching and buckling driving assembly and the wrist form rotary connection rotating around the second axis, and the back stretching and buckling driving assembly can drive the wrist to rotate around the first axis; the first axis is perpendicular to the second axis. According to the humanoid mechanical arm wrist and the humanoid mechanical arm, adaptability and flexibility can be improved.

An improved locking structure of orthopedic steel plate, comprising a steel plate, an outer sleeve and an inner core, the steel plate is provided with a through hole for the screw body to pass through, one end of the outer sleeve is fixedly connected with the steel plate, and the inner hole of the outer sleeve is coaxial with the through hole provided on the steel plate, the inner hole of the outer sleeve forms a guide channel for guiding the screw to be screwed in, and the inner core is detachably arranged in the outer sleeve, and the guide hole in the inner core is used for guiding the drilling of the drill bit. In the operation, the guide hole of the inner core is used to guide the drill bit to accurately drill, so that the lower end of the inner core is matched with the conical internal thread of the through hole, which can effectively constrain the radial deviation of the drill bit and ensure the accuracy of the drilling position. After the drilling is completed, the inner core is taken out, and then the screw is screwed in through the guide channel of the outer sleeve, the guide channel can constrain the radial displacement of the screw, so that the screw accurately passes through the through hole and is screwed into the predetermined position of the bone, avoiding the deviation of the screw into the muscle tissue, greatly improving the safety and accuracy of the operation, and facilitating the installation and disassembly operation according to the needs in the operation.

A hand brace to improving a golfer's short game is disclosed. The brace comprises a shell, a first guard and a second guard. The shell is flexible and configured to cover at least a back portion of the golfer's dominant hand, top of the wrist and lower forearm. The first guard is physically associated with the shell extending along the back of the golfer's dominant hand from and between proximately the second knuckles of the index and ring fingers, over the top of the dominant wrist and lower forearm. The first guard substantially restricts maximum extension of the golfer's dominant wrist to less than approximately 20 degrees. The second guard is physically associated with the shell extending along the back of the golfer's thumb from the nailbed to the first knuckle to substantially restrict radial deviation of the golfer's dominant wrist to less than approximately 10 degrees.
