Description

Ankle joint internal and external rotation stress position maintenance device

technical field

The invention relates to a medical tool, in particular to a device for maintaining the external rotation stress level of the ankle joint.

Background technique

For the repair and health of ankle joint injuries, it is often necessary to test the stability of the ankle joint (using X-ray film to observe the recovery of the ligament, and the width of both sides of the ankle point can also be observed). The traditional method often requires others to move the patient's ankle joint , so that the internal or external rotation of the ankle joint is at a certain angle and maintain the corresponding position, and then exposed to the "X" ray to observe its recovery. , not only the strength is difficult to control, but also the helper will be too much affected by radiation; there is no device on the market that can easily control and maintain a certain angle of external rotation or internal rotation of the ankle joint.

Contents of the invention

The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a device for maintaining the internal and external rotation stress level of the ankle joint that can conveniently control and maintain the stress level of the internal and external rotation angle of the ankle joint. When checking joint stability, there is no need to manually rotate the ankle joint for stress maintenance to perform "X" ray irradiation for inspection.

Principle of the present invention: Ankle joint instability refers to the phenomenon that the ankle joint is unstable after the ligaments around the ankle joint are damaged, which causes frequent ankle sprains. Ankle joint sprains are mainly the anterior talofibular ligament and fibular ligament, which are key to stabilizing the outside of the ankle joint. The calcaneofibular ligament is injured, the mild sprain will make the ligament stretch, and the severe sprain will tear the ligament. If the ligament is slightly stretched, you can rest more, apply Chinese medicine and slowly recover on its own. If the ligament is stretched too long, you can’t For recovery, a small section needs to be cut off, and then the two sections of ligament are rejoined by rolling jointing, so that the ligament can restore its original length and achieve the stability of the ankle joint. The treatment method for torn ligament is also to restore the ligament to health Therefore, to judge whether the ligament treatment is successful, it is necessary to look at the stretching of the ligament after the internal and external rotation of the ankle joint at a certain angle (observe the ligament under the irradiation of an X-ray machine). The function of the device of the present invention is to maintain the internal rotation or external rotation of the ankle joint Rotate at a certain angle, and then take pictures without the help of others to avoid the influence of radiation on others. The main function of the angle sensor and the tension pressure sensor in the present invention is that the angle of internal or external rotation of the ankle joint can be observed intuitively, and the tension pressure generated by the corresponding ankle ligament at a specific angle can be intuitively observed. In this way, the recovery of the ligament can be judged more intuitively, and whether the ligament treatment is successful, and it can also provide data support for subsequent teaching and papers, as well as scientific data for subsequent theoretical research.

The use process of the present invention: when in use, the patient first puts on the shoes 1, then tightens the shoelaces 1-2, then tightens the screw block 9, the rubber pressure pad 8 is pressed against the heel side of the foot, and then puts on the The shank 17 is placed on the top support plate 2-2 of the shank support 2, at this moment, the roller 6 positioned at the support column 1-4 at the bottom of the sole 1-1 heel just rests on the placement plate a, and then uses The inner hexagonal wrench turns the rotating shaft 2-7, and the rotating shaft 2-7 drives the second bevel gear 2-4f, the second bevel gear 2-4f drives the first bevel gear 2-4e, and the first bevel gear 2-4e drives the worm screw one 2-4d, Worm one 2-4d drives worm gear one 2-4c to rotate, and worm gear one 2-4c drives threaded rod one 2-4a and threaded rod two 2-4b to rotate simultaneously, thereby driving two clamping plates 2-3 to move closer to each other and clamp Hold the calf 17, then turn the worm screw 2 4-7, the worm gear 2 4-7 drives the worm gear 2 4-6 to rotate, the worm gear 2 4-6 drives the shaft rod 4-4 to rotate, and the shaft rod 4-4 rotates to drive the push rod 4- 5 moves, the driving force of the push rod 4-5 moves the straight rod 3, thereby driving the shoe 1 to rotate inwardly or outwardly with the foot eye 17-1 as the center of rotation, and when the shoe 1 rotates, it will drive the connecting rod 2 13 to rotate at the same time , so as to drive the angle sensor 11 to rotate at the same time. Through the processing of the information of the PLC controller 15, the angle information and the tension and pressure values transmitted from the angle sensor 11 and the tension and pressure sensor 14 will be displayed on the LCD display 16. When a certain angle value is reached , stop the rotation of the worm 2 4-7, and then use the "X" light to form a shadow, to observe the stability of the ankle joint (that is, the rehabilitation of the ligaments around the ankle joint), and repeatedly adjust different angles and use X-rays Take photos and observe to get the corresponding values, so that you can accurately judge the repair and health of the ankle joint injury. The experimental values obtained can also be recorded and can be used as thesis data and corresponding textbook data, making it easier to obtain intuitive operation data. It will not be judged by accumulating experience like traditional medicine, which is conducive to the dissemination of medical science and is worthy of promotion and application.

Although the invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made within the scope of the claims.
