Description
The present invention is a device for fixing the lower limb joint during X-ray imaging. When orthopedic surgery such as artificial arthroplasty is required, x-rays should be obtained by capturing an X-ray with the foot or leg in position, since it is necessary to precisely match the normal leg and the length and position of the leg during surgery . The present invention relates to an apparatus for obtaining an x-ray image after easily positioning a pre-operative pair of feet.
In orthopedic surgery, operations such as replacing joints with artificial joints such as hip joint arthroplasty and Knee joint arthroplasty have been performed for elderly people relatively. Most patients with joint anomalies are asymmetrical with each other and have different lengths and angles. However, for surgery, there should be information about the normal (non-asymmetric) state of the foot or leg (such as the shape of the joint area). In other words, the position of both legs in a normal state prior to surgery must be ascertained, so that the surgeon can perform surgery such as artificial joint replacement in a normal state in the surgical procedure. Otherwise, there is a risk that you will not be able to reach a successful operation, even if you have had surgery, but your legs differ in length or angle.
That is, X-ray images of the joints should be grasped in a state where both legs or both feet are properly positioned in a normal state before orthopedic arthroplasty.
FIG. 1 shows a conventional method of photographing a leg state of a patient.
1, in the conventional X-ray imaging, a patient is placed on the bed 2 of the X-ray imaging apparatus 1, the medical person 1 grasps the patient's foot, and the medical doctor 2 holds and fixes the upper body of the patient. This may cause pain to the patient if both legs are in an asymmetric state and both legs are fixed in position for imaging, and since it is difficult for the patient to maintain the correct position, So that the position and angle of the leg of the patient can be maintained at an accurate position. However, if necessary, it may be possible to fix the patient's leg with only the medical person 1, not the medical personnel 1 and 2.
Then, the medical person 4 (radiologist) operates the x-ray equipment and the medical person 3 checks the desired image through the x-ray monitor. The medical practitioner 1 or the medical practitioner 2 keeps the patient's foot in the radiation room until the desired image is obtained and keeps the patient in the radiation room until the correct image is obtained by turning the patient's foot little by little according to the instruction of the medical practitioner 3 or the medical practitioner 4. A shielding wall (W) is located between the radiological room where the x-ray equipment is located and the medical practitioner 3 or the medical practitioner 4.
In this conventional system, at least three to four medical personnel are required, and since the medical personnel 1 to 2 holding the patient's body continue to stay in the radiation room, there is a risk that the medical person is covered with radiation.
In addition, since the conventional method relies on the hands of the medical person to fix the patient's body, if the hands of the medical person holding the patient's leg are moved, it is difficult to accurately capture the images. Also, If it does not work well, it takes a lot of time because it is necessary to repeatedly shoot the image repeatedly, and there is a problem that it gives pain to the patient who is a photographer.
In order to solve the above problem, the present invention is to provide a method for efficiently imaging a foot of a patient before orthopedic surgery, requiring a small number of medical personnel,
The radiological room where the x-ray is taken prevents the radiologist from staying,
It is intended to provide a means capable of quantitatively measuring whether the foot of the patient is twisted compared with the original position.
The present invention includes a first foot-receiving member (110) to which a right foot is inserted and fixed; A second foot receiving member 120 to which a left foot is inserted and fixed; A connecting member 130 connecting the first and second foot-receiving members to each other; And a fixing member (150) for fixing the connecting member to the bed of the X-ray imaging apparatus.
The first and second foot accommodating members and the second foot portions are provided with a handle 140 for adjusting the tilting angle. The first and second foot accommodating members are shoes that are inserted and wrapped around the toes, A Velcro for fixing can be provided.
The connecting member 130 is connected to the lower ends of the first and second foot accommodating members and can adjust a distance between the first and second foot accommodating members. And is connected to the connecting member so as to be tiltable with respect to the connecting member.
The connecting member 130 is provided with a display unit for displaying a distance between the first and second foot-receiving members and a tilted angle of rotation.
The fixing member may be a C-shaped clamp, that is, a groove into which the coupling member 130 is inserted and a bolt to be fixed to the bed.
In the present invention, by using the above-mentioned foot fixing means, a medical person can fix and photograph the foot, and prevent the radiographer from staying in the radiation room, thereby preventing radiation exposure. Or the like is distorted or distorted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Even if the terms are the same, it is to be noted that when the portions to be displayed differ, the reference signs do not coincide.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
FIG. 2 is a schematic view of an X-ray imaging system according to an embodiment of the present invention, FIG. 3 is a perspective view of a fixed-lower limb position fixation apparatus according to an embodiment of the present invention, It is a view from the left side of the position fixing device.
The apparatus for fixing the lower limb of the lower limb used for x-ray imaging according to an embodiment of the present invention includes a first foot accommodating member 110 to which a right foot is inserted and fixed and a second foot accommodating member 120 ).
The first and second foot accommodating members are formed in a shoe shape in which a foot is inserted and wrapped around the ankle so that the ankle is formed to have a long neck so as to fix the ankle and the overall size is formed to be long so as to cover the calf. This is because x-rays of the knee area are necessary because of knee joint surgery, so do not cover your knees.
Since the first and second foot accommodating members are firmly fixed so that the ankle does not move after the feet are inserted, a plurality of the velcro fasteners 115 and 125 for firmly fixing the inserted foot can be provided have.
The leg joint correcting device of the present invention includes a connecting member 130 connecting the first and second foot-receiving members to each other. The first and second foot-receiving members are for fixing the distance and angle between each other in a state where the feet are inserted. It is preferable that the connecting member 130 is connected at the sole portions of the foot-shaped first and second foot-receiving members.
In addition, the connecting member 130 is connected to the lower ends of the first and second foot-receiving members, and the first and second foot-receiving members are connected to each other so as to control the distance between the first and second foot-receiving members. That is, when the distance between the left foot and the right foot is not appropriate, the distance between the left foot and the right foot should be reduced or increased. Therefore, the foot accommodating member is connected to the connecting member so as to control the distance (separation distance) therebetween.
As shown in FIG. 5, the left foot or the right foot may be tilted (tilted or tilted) in the left-right direction with respect to the connecting member 130. That is, when the degree of inclination or tilting of the left foot and the right foot is not appropriate, the foot accommodating member is connected to the connecting member so that the degree of inclination can be adjusted.
The connecting member 130 is provided with a display unit 135 (see FIGS. 4 and 5) for displaying a distance between the first and second foot-receiving members and a tilted angle of rotation, It is good to be able to numerically confirm this by a medical practitioner who controls. In order to detect the tilting angle and display the tilting angle on the display unit, a sensor (not shown) for detecting the degree of tilting may be provided therein.
A means (not shown) for fixing the first and second foot-receiving members so that they do not move relative to the connecting member after the angle and distance of the feet are adjusted (i.e., the set distance or angle is not twisted) Which may be a locking device to prevent relative rotational movement or linear movement of the foot accommodating member or the connecting member, and the locking device is not limited to a specific one method, It will be possible to apply.
In addition, these numerical data may be recorded on a storage medium, and then used as a data after the operation or after the operation. In FIG. 5, the distance and tilting angle are adjusted. In the figure of Fig. 5, there is a scale indicating the distance on the connecting member so that the distance between the left and right can be visually recognized. As shown in FIG. 5, the connecting member is provided with a scale indicative of the distance, and a protractor is attached to the connecting portion of the connecting member and the first and second foot-receiving members to visually confirm the tilted scale . In FIG. 5, the protractor is illustratively shown only on the left fixing member, but it is needless to say that the protractor can be displayed on the right fixing member in the same manner.
For adjusting the separation distance and the tilting angle, the first foot accommodating member and the second foot are provided with a handle 140 for adjusting the tilting angle. The handle 140 may be provided on the sole of the first foot accommodating member and the second foot accommodating member in the form of a shoe so as to be easy to use and may be a substantially b-shaped member.
FIG. 6 is a view showing a state where the lower limb fixed position fixing apparatus according to the present invention is fixed to the bed of the X-ray imaging apparatus. Preferably, the lower limb fixed position fixation device is firmly fixed to the bed of the X-ray imaging apparatus. This is to prevent the shape of the patient's feet or legs from changing during shooting due to the twisting.
In the present invention, the connecting member 130 is fixed to the bed of the X-ray imaging equipment. The fixing member 150 used here may be a simple C-shaped clamp or a C-shaped clamp.
FIG. 6 illustrates one exemplary embodiment. In the fixing member 150, a groove is formed on the inner side of the fixing member 150 to prevent movement of the connecting member 130. The fixing unit 150 is fixed to the bed of the X-ray imaging equipment using the bolts 155 at the lower end.
FIG. 7 shows a state where the lower limb fixed position fixing apparatus according to another embodiment of the present invention is fixed to the bed of the X-ray imaging apparatus.
7 is substantially the same as that described above, except that the connecting member 130 is firmly fixed to the bed 2 of the X-ray imaging apparatus and is firmly fixed. There are various methods of fixing the connecting member 130 to the bed 2, and in FIG. 7, for example, the connecting member is completely tightly fixed to the bed by using a clamp and a bolt.
Hereinafter, a procedure for photographing using the present invention is described.
First, the patient is laid on the bed of the X-ray imaging apparatus, and both feet of the patient are inserted into the fixed joint of the lower limbs of the present invention to fix the velcro.
Then, the distance and angle of the patient's feet are fixed, and the radiograph is taken after the radiologist leaves the radiological room. That is, according to the present invention, since the medical person does not need to hold the patient's foot while staying in the radiation room, the risk of covering the medical person is lost. When it is necessary to change the distance or angle of the patient's foot, the user is required to go back into the radiation room, adjust the fixed joint of the lower limbs, and then go out of the radiological room and shoot using the radiographic equipment. According to the present invention, there is an advantage that a medical person who needs to hold a patient in a radiation room becomes unnecessary.
Therefore, according to the present invention, as described above, by fixing the fixation device for ankle joint according to the present invention to a bed of an X-ray imaging apparatus, a medical person can take one or two images and the foot of the patient is firmly fixed, It becomes possible to quantitatively measure whether the patient is twisted a few degrees relative to the original posture, to eliminate the risk of radiological covering of the medical personnel, to quantitatively measure the angle and length of the hip joint, The image taking time is shortened compared with the conventional method.
