Description

Ankle trauma fixation device

Technical field

The invention relates to the technical field of medical auxiliary devices, and in particular to an ankle trauma fixation device.

Background technique

Ankle trauma is a common injury in daily life. The ankle joint is an important load-bearing joint, and its stability is crucial to the walking and movement functions of the human body. However, the ankle joint is also one of the most easily injured joints, often resulting in ankle bone trauma due to sprains, falls, car accidents, etc. In these cases, ankle immobilization is necessary treatment.

Ankle immobilization is the process of immobilizing the injured ankle using various methods to reduce pain, prevent swelling, and promote healing. After an ankle injury or orthopedic surgery, immobilization can provide the necessary support and stability to help restore normal function to the ankle joint. Currently, a variety of methods are available for ankle immobilization. Among them, cast immobilization is a common fixation method, which wraps the injured ankle joint in a plaster. This method provides good support and stability, but it takes time to create and dry, and the plaster is cumbersome to remove. In addition, there are some wearable fixation devices, such as ankle braces, braces, etc., that can provide flexible support and protection.

However, existing ankle fixation methods only limit ankle movement but cannot completely prevent ankle support. When walking, patients often need to use crutches or other assistive devices to support their weight and avoid landing on the soles of their feet. This makes it inconvenient for patients to walk, and they are prone to accidentally landing on the soles of their feet, which affects bone recovery.

Contents of the invention

The purpose of the present invention is to provide an ankle trauma fixation device. After being worn, the patient can walk without the support of tools such as crutches. The ankle is not supported when walking, which is more conducive to the recovery of ankle bones.

The above technical objectives of the present invention are achieved through the following technical solutions: an ankle trauma fixation device, which includes a sole support plate, an outer foot cover is provided upward on the edge of the sole support plate, and the upper end of the sole support plate is at The outer foot cover is provided with a support cushion that matches its shape. The edge of one end of the outer foot cover is upwardly provided with an outer ankle cover that matches the position of the human ankle. The edge of the outer foot cover and the The edges of the outer ankle cuff are provided with multiple external fixation straps;

Both sides of the outer ankle cuff are provided with lower connecting bars upward. The upper end of each lower connecting bar is provided with a telescopic bar upward. Each telescopic bar is slidably connected with a sliding sleeve arranged along its height direction. The middle part of each sliding sleeve is There are adjustment sleeves connected to the outside, and a knob is connected to the outside of each adjustment sleeve. Each knob is connected to a threaded shaft that extends into the corresponding adjustment sleeve. Each adjustment sleeve is slidably connected with an insulator. Rotating sliding limit blocks, each sliding limit block is provided with a threaded hole that is threadedly connected to the corresponding threaded shaft, the outside of each telescopic bar is provided with transverse teeth, and the inside of each sliding limit block is provided with Limiting teeth that match the corresponding transverse teeth;

An ankle cuff with matching ankle shape, the edges of the foot cuff and the ankle cuff are provided with a plurality of internal fixation straps.

By adopting the above technical solution, after the patient's ankle trauma, the patient's foot and ankle are first covered with an inner foot cuff, and the internal fixation belt is used to wrap and fix the patient's ankle so that the patient's ankle cannot move, and then the outer foot cuff is inserted into the patient's ankle. Inside, make the foot pad of the inner foot muff contact the supporting cushion, wrap and connect with the external fixation belt, fix the foot and ankle in the outer foot muff and outer ankle muff, turn the knob, and make the threaded shaft drive the sliding stopper to slide outward. , keep the limiting teeth away from the transverse teeth on the telescopic bar, then you can freely adjust the relative lengths of the telescopic bar and the sliding sleeve, put the knee sleeve on the patient's knee, put the soft sleeve behind the knee behind the knee, and use the connecting The belt is connected to the knee sleeve. Finally, adjust the relative length of the telescopic bar and the sliding sleeve so that the foot pad of the inner foot sleeve can just press on the support cushion. Finally, turn the knob so that the threaded shaft drives the sliding limit block to slide inward, driving the sliding The limit teeth on the limit block are engaged with the transverse teeth on the telescopic bar to lock the length of the telescopic bar and the sliding sleeve.

A further configuration of the present invention is that the edges of the outer foot cuff and the outer ankle cuff are both provided with matching first connecting rings, one of the first connecting rings on one side is connected to the outer fixing strap, and each The free ends of the external fixation straps can pass through the matching first connecting ring on the other side. The outside of each external fixation strap is provided with matching suede Velcro and hook-surface Velcro.

A further arrangement of the present invention is that the free end of each rotating connecting bar is provided with a second connecting ring, both sides of the soft back knee connecting sleeve are connected with connecting belts, and the free end of each connecting belt can be connected from the corresponding third connecting ring. The free ends of the two connecting rings pass through, and matching suede Velcro and hook Velcro are provided on the outside of each connecting band.

A further configuration of the present invention is that: the outer sides of the foot wrap and the ankle wrap are both provided with suede Velcro, and the inside of each internal fixation strap is provided with hook Velcro.

A further configuration of the present invention is that each threaded shaft penetrates inwardly through a corresponding sliding sleeve to connect the limiting piece, and a strip-shaped perforation is provided through each telescopic bar along its height direction and capable of allowing the corresponding threaded shaft to pass through.

To sum up, the present invention has the following beneficial effects:

First, the present invention uses an inner foot cuff to fix the patient's ankle so that it cannot move, so that the ankle bones can slowly recover, and the telescopic strip and sliding sleeve between the sole support plate and the knee cuff serve as a fixed support. , can directly transmit the support force of the sole support plate in contact with the ground to the knee, avoiding the ankle support and being directly supported by the knee, so that the patient can walk without the support of crutches after ankle trauma, and the ankle cannot lift during walking. Supporting effect, more conducive to ankle bone recovery;

Secondly, the length of the telescopic bar and sliding sleeve can be freely and quickly adjusted according to the actual situation to meet the needs of different patients;

Third, the knee sleeve is rotationally connected to the upper connecting strip, allowing the knee to bend freely, making the patient more comfortable to wear and move more freely.
