Description

Radial Slope Response Immobilizer The present invention relates to a fixation device corresponding to the radial inclination. The number of patients requiring shoulder joint replacement surgery is increasing, ranging from those with shoulder dislocation instability in the younger age group to those with impingement syndrome, frozen shoulder, and rotator cuff tears in the middle-aged. For these patients, the most critical aspect after surgery is successfully restoring and maintaining the range of motion. Additionally, frozen shoulder, which affects approximately 1% of the population and causes reduced range of motion and pain, requires treatment focused on restoring the range of motion. Furthermore, if specific parts of the brain are damaged due to reasons such as stroke, cerebral hemorrhage, or traumatic brain injury, unilateral or bilateral upper limb motor paralysis may occur; in the case of the upper limbs, which possess a wide range of motion, treatment to maintain continuous range of motion is crucial. However, there is still a shortage of specialized medical personnel responsible for the treatment of restoring and maintaining joint range of motion compared to the number of patients, and due to the physical limitations of medical staff, it is difficult for patients to receive sufficient and satisfactory joint exercise therapy. For this reason, therapeutic robots, such as manual therapy robots, are being introduced recently to assist the therapist's efforts and the treatment process. Upper extremity joint movement therapy robots can not only induce sufficient, consistent, and high-intensity training for patients but also standardize training by adjusting repetitive force, training volume and time, and quantifying the progress and outcome of training, thereby reducing the physical burden on therapists. The upper extremity joint movement therapy robot includes a robotic arm and a forearm fixation device coupled to the robotic arm to secure the patient's forearm. By moving the forearm fixation device, the robotic arm can perform therapy to restore and maintain the patient's upper extremity joint range of motion. Depending on the structure of this forearm fixation device, the range of motion of the robotic arm and the force required for its movement may vary, which directly affects the effectiveness of the therapy for restoring and maintaining the patient's upper extremity joint range of motion. On the other hand, in a normal wrist, when making a fist in the neutral position, the little finger is positioned closer to the proximal end (wrist side) compared to the index finger. This is due to the radial inclination in the wrist. However, conventional forearm fixation devices had a problem in that the radial inclination of the wrist was not reflected in the handle gripped by the patient, which increased wrist fatigue. In addition, conventional forearm fixation devices had the problem of lacking versatility because the fixation point with the robot arm was limited to a specific point.
