Description

Technical Field

[0001] This invention relates to the field of orthopedic surgery technology, and in particular to a hand bone fixation component. Background Technology

[0002] During orthopedic surgery on the hand, the hand needs to be immobilized to prevent injury from bone movement and disruption of the procedure. This is typically achieved using a fixation device.

[0003] The currently used fixing components have the following disadvantages:

[0004] 1. The current fixation components require binding the arm for fixation, but lack the function of quickly binding the entire wrist, which is not conducive to completely fixing the arm;

[0005] 2. Lacks the function of fixing the binding position;

[0016] The beneficial effects are as follows:

[0017] 1. The movable outer frame provides the function of quickly binding the entire circumference of the arm. The third motor, in conjunction with the worm gear, rotates to drive the transmission gear, which in turn drives the arc rack and the movable outer frame to rotate half a turn. This unfolds the binding strap outside the binding strap wheel and puts it on the outside of the arm, thus fitting the arm in place. The adjusting worm gear and adjusting worm can be self-locking to control the position of the movable outer frame, making it convenient to bind and fix the arm.

[0018] 2. The brake clamp is provided to fix the binding position. When the second piston is compressed and contracted, the air inside the second piston is input to the outside of the air telescopic rods B and C. Due to the force of the spring outside the spring rod, the clamp first adheres to the brake wheel, and then the air telescopic rod C extends, dragging the connecting plate to the left. Then the U-shaped frame is pushed to the left, which drives the moving outer frame to be pushed to the left, tightening the abdominal binding strap, fixing the wrist part, and maintaining the tightness of the binding.

[0019] 3. The finger restraint strap provides a quick fixation function for the fingers. The first motor is started to drive the threaded cylinder to rotate. The threaded cylinder, in conjunction with the control screw, moves to the left, stretching the piston plate outward. This reduces the internal pressure of the first piston, which in turn retracts the pneumatic telescopic rod A. The pneumatic telescopic rod A pulls down the finger restraint strap, thus fixing the patient's fingers and completing the binding. Attached Figure Description
