Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an ankle joint stress position X-ray photography auxiliary device. Background Art
[0002] When a patient takes an ankle stress X-ray or magnetic resonance imaging, if the affected ankle joint is not fixed, the patient's joint may move randomly, affecting the imaging effect of the examination and failing to meet the shooting requirements.
[0003] Ankle injuries can affect both bony and soft tissue structures. The principle of treatment is to restore the stability of the ankle joint, which depends on the reduction and fixation of the fracture on the one hand, and on the other hand, requires the repair and reconstruction of soft tissue structures such as ligaments. When surgical treatment of ankle injuries is used, intraoperative X-rays are a necessary means to determine the stability of the ankle joint. Currently, the most commonly used ankle X-rays include anteroposterior, lateral, inversion, and eversion films. Obtaining standard X-rays during surgery is of great significance for determining the effect of fracture treatment.
[0004] In the prior art, when performing ankle X-rays, doctors manually position and maintain the position of the affected limb, but there are the following defects: when manually positioning the body, there are differences between different doctors, resulting in poor repeatability of X-rays; there is a lack of spatial reference when manually positioning the body, and it is often necessary to repeatedly position and take pictures to obtain a standard X-ray; when taking pictures, the doctor needs to stand near the camera, which increases the risk of radiation exposure. Utility Model Content
[0005] The purpose of the utility model is to provide a multifunctional ankle joint stress position X-ray fixation device to solve the technical problems existing in the prior art, aiming to improve the efficiency of medical staff during operation, facilitate medical staff to use and achieve good results.
[0006] The technical idea of the utility model is:
[0007] (1) Design a structure that allows doctors to easily invert the patient's ankle joint to a suitable limb position and maintain the limb position until the end of the X-ray.
[0008] (2) Design a structure that allows doctors to flexibly adjust the inversion force of the patient's ankle joint so that the patient's ankle joint is in an inversion position and has a good fixation effect.
[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0010] The utility model discloses an ankle joint stress position X-ray photography auxiliary device, comprising a base plate, a calf fixing part for fixing the patient's calf is arranged on the base plate, and an ankle joint flip adjustment part for adjusting the foot flip angle is arranged at the front end of the base plate.
[0011] In order to facilitate medical staff to fix the patient's calf area and prevent the patient's joints from moving randomly, a further optimization scheme of the utility model is as follows: the calf fixing part includes a calf stabilizing plate and a fixator, the calf stabilizing plate is tilted on the base plate through the support plate, and the calf stabilizing plate is detachably connected to the base plate, and fixators are correspondingly arranged on the left and right sides of the base plate.
[0012] Furthermore, the fastener is a plurality of elastic straps and fastening buckles corresponding to each other.
[0013] In order to facilitate medical staff to adjust the patient's limb position to an inversion position and to facilitate X-rays, a further optimization scheme of the utility model is: the ankle joint flip adjustment part includes an airbag and a fixing plate, the front end of the bottom plate is vertically provided with a fixing plate, and inflation holes are symmetrically provided on the left and right sides of the upper end of the fixing plate, and airbags are correspondingly provided at the inflation holes.
[0014] Furthermore, a circular arc-shaped heel placement groove is provided at the front end of the calf stabilization plate.
[0015] The beneficial effects of the utility model are:
[0016] (1) The ankle joint stress position X-ray photography auxiliary device adopts the method of adding air bags on the left and right sides, so that medical staff can flexibly choose to inflate one of the air bags when using it, and flip the patient's foot around the ankle joint. The flipping angle can be flexibly controlled by the inflation amount, and the force is gentle, which will not cause secondary injury to the patient. After the filming is completed, the inflation device is withdrawn, and the flipping state of the patient's foot can be restored. It is very convenient to use.
[0017] (2) By adjusting the inflation volume of the airbag to adjust the flip angle of the patient's foot, the patient's joints can be prevented from moving arbitrarily. The foot can be displaced inward relative to the calf (talus relative to tibia), meeting the requirements for X-ray shooting of the inward stress position. This saves the labor cost of manual positioning during shooting, ensures that the stress size is relatively accurate, and reduces the occurrence of errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Example 1
[0026] Combination Figures 1 to 5 The utility model discloses an ankle joint stress position X-ray photography auxiliary device, including a base plate 1, on which fixing grooves 103 are symmetrically opened front and back, the total number of fixing grooves 103 is two, and the fixing grooves 103 are rectangular parallelepiped structures, the fixing grooves 103 are used to insert the support plate 5, the support plate 5 and the fixing grooves 103 are transitionally matched, and when the support plate 5 is inserted into the bottom of the fixing grooves 103, the two can be fixed, so that the whole device can be easily disassembled and installed. A fixing plate 101 is fixedly connected to the rear end of the base plate 1, and the fixing plate 101 is a rectangular parallelepiped structure, and the base plate 1 and the fixing plate 101 are perpendicular to each other.
[0027] It should be noted that the length of the support plate 5 on the side close to the fixing plate 101 is greater than that of the support plate 5 on the side away from the fixing plate 101. A fixing buckle 2 is provided on the left side of the bottom plate 1, and a square hole 201 is provided on the fixing buckle 2. Correspondingly, an elastic band 3 is provided on the right side of the bottom plate 1. The elastic band 3 passes through the square hole 201 and is fixed by the fixing buckle 2. The size of the square hole 201 is adapted to the elastic band 3. When in use, Velcro can be used to fix it, or the elastic band 3 can be passed through the square hole 201 multiple times. In this embodiment, the number of fixing buckles 2 is set to two, and correspondingly, the number of elastic bands 3 is also set to two, which are used to fix the patient's calf.
[0028] Exemplarily, the elastic bandage 3 tied at the calf position adopts a thicker design, such as a thickness of 3-5 cm, and a layer of flexible material is sewn or glued on the side of the elastic bandage close to the leg, so that it can wrap better, fix more securely, and be more comfortable for patients to use.
[0029] Since the lengths of the two support plates 5 are different, the calf stabilizing plate 4 on the support plate 5 is inclined, the height of the calf stabilizing plate 4 near the fixed plate 101 end is higher, and a heel placement groove 401 is provided at the front end of the calf stabilizing plate 4 near the fixed plate 101 end, and the heel placement groove 401 is arc-shaped.
[0030] Airbags 6 are arranged at the left and right sides of the fixing plate 101 corresponding to the heel placement groove 401. The number of airbags 6 is two, and an inflation hole is arranged at the installation position of the fixing plate 101 and the airbag 6. An inflation interface 601 is arranged behind the inflation hole, so that medical staff can use an inflation device to inflate the airbag 6 through the inflation hole.
[0031] Specifically, the pressure of the airbag 6 is controllable, and the inflation pressure can be set according to the patient's weight.
[0032] When in use, one of the two airbags 6 is kept inflated and the other is not inflated. If the left airbag 6 is inflated, as the airbag 6 gradually becomes larger, the patient's foot will slightly rotate to the right around the ankle joint, and vice versa. The angle of rotation increases as the amount of gas inside the airbag 6 increases. This can facilitate the medical staff's regulation and control, and the force is appropriate without causing secondary damage to the patient's ankle joint.
[0033] Application Cases
[0034] This embodiment describes the application of the utility model in the field of medical device technology. When it is necessary to perform an X-ray of the patient's ankle joint, the base plate 1 is placed at a suitable position corresponding to the patient's calf, the support plate 5 is inserted into the fixing groove 103, the calf stabilizing plate 4 is fixed, the patient's calf is fixed on the calf stabilizing plate 4, and the patient's heel is stabilized in the heel placement groove 401, and the patient's calf is fixed with the elastic bandage 3 and the fixing buckle 2. At this time, both airbags 6 are in an uninflated state. Combined with the patient's left or right foot, one of the airbags 6 is flexibly inflated according to actual needs. It should be noted that if the left airbag 6 is inflated, as the airbag 6 gradually becomes larger, the patient's foot will slightly rotate to the right around the ankle joint, otherwise it will rotate to the left, and the rotation angle will increase as the amount of gas inside the airbag 6 increases. Thus, a standard inversion X-ray of the patient's ankle joint is taken. After the filming is finished, the inflation device is withdrawn, the airbag 6 is deflated, and the patient's foot can be restored to its original position.
