Description

Technical Field

[0001] This utility model relates to the field of nursing equipment technology, specifically to an ankle device for preventing foot drop. Background Technology

[0002] Foot drop is one of the signs in orthopedic surgery. When the patient is sitting with both lower limbs hanging naturally, if the foot is in plantarflexion and cannot be actively dorsiflexed, inverted, or everted, then it is foot drop. This sign can be seen in sciatic nerve palsy and common peroneal nerve palsy. In the former, the toes cannot be dorsiflexed or plantarflexed; while in the latter, the toes can be plantarflexed. This can be used to differentiate between the two.

[0003] Existing ankle devices for preventing foot drop have the following drawbacks: they are often fixed in place, making it difficult for people to adjust their leg position while carrying the device. Maintaining the same position for a long time is not conducive to leg training and activity, and is very inconvenient. Utility Model Content

The installation cylinder is movably connected to the base plate via a connecting seat. The bottom end of the threaded rod is movably inserted into the interior of the installation cylinder, and the top end of the threaded rod is movably connected to the limiting plate via a connecting seat. The locking nut is threaded into the top end of the installation cylinder and threaded onto the outside of the threaded rod. The shock absorption mechanism includes an installation frame, a spring shock absorber, an installation plate, a connecting plate, a rotating shaft, and an electric push rod. The installation frame is fixedly installed on the top of the base plate, and the spring shock absorber is fixedly installed on the bottom inner wall of the installation frame. The top end of the spring shock absorber is fixedly connected to the connecting plate.

[0007] Furthermore, the electric push rod is fixedly installed inside the mounting plate, the output end of the electric push rod is fixedly connected to the connecting plate, one end of the rotating shaft is movably inserted into the interior of the mounting plate, and the other end of the rotating shaft is fixedly connected to the limiting plate.

[0008] Furthermore, the installation mechanism also includes straps, Velcro 1, Velcro 2, sleeves, telescopic rods, plug-in plates, extension plates, and screws. The limiting plate is configured as an L-shaped plate. One end of the strap is fixedly connected to the outer walls of both sides of the limiting plate. Velcro 1 is disposed on one outer wall of one side of the strap, and Velcro 2 is disposed on the other outer wall of the other strap.

[0009] Furthermore, the straps are provided in multiple sets, and protruding posts are fixedly installed on both outer walls of the limiting plate and the extension plate.

[0010] Furthermore, one end of the sleeve is movably sleeved on the outside of the protrusion on the limiting plate, and one end of the telescopic rod is movably sleeved on the outside of the protrusion on the extension plate.
