[0001] The utility model relates to medical auxiliary instrument technical field, concretely, relate to a body position of lower limb radiological examination contrast is placed fixed device. BACKGROUND

[0002] In the orthopedics, for the patients of fracture, bone fracture, joint dislocation and so on, often need to be checked through radiological contrast. Among them, X-ray film and CT are the preferred inspection method. For the patients with upper limb fracture or joint dislocation, the patient himself or with the assistance of medical staff can be well placed in the detection area the part to be inspected, but for the patients with lower limb fracture or joint dislocation, often inconvenient, although there is medical staff's assistance, but due to the consideration of the severe pain of the part to be inspected of the patient, it will lead to the inaccurate placement of the lower limbs of the patient, so that the effect of the taken contrast film is poor.

[0003] In the prior art, for the inaccurate body position of the lower limbs of the patient during radiological examination, many devices for fixing the lower limbs are designed. For example, the utility model discloses a kind of body position fixing device for lower limb contrast, two lower limb plates are installed on one side of hip plate, lower limb plate can swing along horizontal plane direction, when using, the device is placed on examination bed, the pillow is placed under the upper limbs of examinee, hip is placed on hip plate, left and right legs are placed on lower limb plate, and examinee's limbs are bound with lower limb plate using restraint belt, and are fixed using magic tape. The position of lower limb plate is swung to move the lower limb part to be detected of the patient. For example, the utility model discloses a kind of lower limb radiotherapy fixing frame, the fixing frame is inserted into different ring grooves according to the thickness of the leg of the patient by inserting assembly, so as to realize the fixation of the leg of the patient, then the whole device is moved, and the body position of the lower limbs of the patient is fixed.

[0004] The two devices mentioned above, the fixing device with publication number CN211326536U is mainly used for the body position fixation of the two legs of the patient, but if the patient only needs to fix the body position of single leg, the other lower limb plate placed on the examination bed will hinder the body position of the patient. The fixing frame with publication number CN213077245U can only fix the body position of single leg, if the patient needs to radiologically examine both legs, another fixing frame needs to be placed on the examination bed, so medical staff needs to prepare at least two such fixing frames, which increases the use cost.

The end of the rotating rod is fixedly connected to the end of the lower limb plate. The sleeve is fitted onto the rotating rod, and the rotating rod is rotatably connected to the inner wall of the sleeve. One end of the sleeve is located inside the side cavity. A sealing cavity is opened inside the end of the sleeve near the side cavity. One end of each of the two sets of limiting devices is located inside the sealing cavity, and the other end is in contact with the inner wall of the rotating rod and the connecting rod, respectively. A through groove is provided at the bottom of the connecting rod along its length.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Two lower limb plates are designed with an arc-shaped cross-section. The arc-shaped plates are inserted into the grooves of the limiting block. Both the arc-shaped plates and the limiting block have through holes of the same size. A fixing rod passes through these through holes to fix the rotation angle of the lower limb plates. When an angiography is needed on a single lower limb, simply rotate the lower limb plates and align their edges to form a U-shaped cross-section to position and fix the patient's leg. This not only improves the applicability of the device but also makes full use of the two lower limb plates, preventing them from hindering patient positioning during angiography on a single lower limb.

[0021] 2. Connect the ends of the two lower limb plates to the rotating rod of the connecting mechanism. The rotating rod allows the lower limb plates to rotate around its axis. At the same time, a felt surface is provided on the back of the corresponding fixing straps of the two lower limb plates. This not only combines the two lower limb plates into a U-shaped structure to fix the position of a single leg, but also allows the lower limb plates to rotate 180° around the axis of the rotating rod. Combined with the adhesive effect of the fixing straps and the felt surface, it achieves the effect of clamping and fixing the patient's lower limb.

[0022] 3. A sealing cavity is opened in the sleeve, and a cylindrical body communicating with the sealing cavity is set at the bottom of the sleeve. Limiting devices that can abut against the inner walls of the rotating rod and the connecting rod are set on both sides of the sealing cavity. In addition, a piston is set inside the cylindrical body, and the piston is fixedly connected to the end of the rotating rod. In this way, by rotating the rotating rod, the piston squeezes the space inside the sealing cavity. Under the action of fluid, the two limiting devices can simultaneously and tightly contact the inner walls of the rotating rod and the connecting rod, thereby fixing the rotation angle and horizontal position of the lower limb plate. The operation is convenient.

[0023] 4. The rotating plate connected to the heel support is rotatably connected to the second slider. The limiting plate can abut against the rotating plate. One end of the limiting plate and the push rod are both located in the cavity. The push rod and the second slider are connected by a thread. In this way, the internal space of the cavity is compressed by the push rod, and the fluid pushes the limiting plate, so that the limiting plate contacts the rotating plate. This can realize the adjustment and fixation of the inward and outward rotation angle of the heel support. Attached Figure Description

Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0042] Reference Figures 1-13 The image shown is a preferred embodiment of the present invention.

[0043] Example 1: A positioning and fixing device for lower limb radiographic imaging includes two lower limb plates 1 with arc-shaped cross-sections and a connecting rod 4. In this example, the connecting rod 4 is installed directly below the two lower limb plates 1. During use, the connecting rod 4 is placed on the examination table. To ensure that the lower limb plates 1 fit well against the patient's lower limbs, a sponge pad 3 is attached to the concave surface of the lower limb plates 1. A groove 7 with an open top is opened along the length of the connecting rod 4. A connecting mechanism is installed between the lower limb plates 1 and the connecting rod 4 to connect them.

[0044] In this embodiment, as Figure 2 and Figure 4 As shown, the connecting mechanism mainly consists of a slider 8 and a U-shaped limiting block 11. The slider 8 is slidably installed in the groove 7 of the crossbar, thus adjusting the distance between the two lower limb plates 1. The bottom of the limiting block 11 is inserted into the slider 8, and the bottom of the limiting block 11 protrudes, allowing the limiting block 11 to rotate along the horizontal plane, thereby adjusting the horizontal swing angle of the arc plate 10. Figure 4 The limiting block 11 has a U-shaped side, with a through hole 9 on each of its two side walls. The lower limb plate 1 has an arc-shaped cross-section, and an arc-shaped plate 10 is fixedly installed on the bottom surface of the lower limb plate 1. Multiple through holes 9 of equal arc length are formed on the arc-shaped plate 10, and these through holes 9 are the same size as the through holes 9 on the limiting block 11. To fix the angle of the lower limb plate 1, this embodiment also includes a fixing rod 12 that matches the size of the through holes 9. When the through holes 9 on the arc plate 10 correspond to the through holes 9 on the limiting block 11, the fixing rod 12 is passed through the through holes 9, thus completing the fixation. To prevent the lower limb plate 1 from rotating, the inner walls of the through holes 9 on the limiting block 11 and the arc plate 10 are threaded, and the side wall of the fixing rod 12 is also threaded. When aligned, the fixing rod 12 rotates into the through holes 9, thus fixing the lower limb plate 1. If only a single lower limb of the patient needs to be examined, the lower limb plate 1 can be rotated to the desired angle. Figure 3As shown, a lower limb plate 1 with an overall cross-section of U is formed. The patient simply places the lower limb to be examined on the two lower limb plates 1.

[0045] In this embodiment, in order to conform to ergonomic design, the cross-sectional width of the distal end of the lower limb plate 1 is smaller than that of the proximal end. When fixing the position of a single leg, the lower limb plate 1 needs to rotate around the limiting block 11 so that its side fits.

[0046] In this embodiment, to secure the patient's lower limbs, two adjustable-length fixing straps 6 and Velcro 5 are provided on the side of the lower limb plate 1. The fixing straps 6 and Velcro 5 are connected as follows: Figure 1 The lower limbs are spaced apart, with a felt surface 13 on the back of the lower limb plate 1 and an adhesive strap 6. When it is necessary to position and fix the patient's two lower limbs separately, the strap 6 can be wrapped around the patient's lower limb and directly bound to the felt surface 13 on the back of the same lower limb plate 1 to achieve lower limb fixation. If it is only necessary to position and fix a single lower limb, such as... Figure 5 In this way, after adjusting the length of the fixing strap 6, stick it onto the Velcro 5 to achieve fixation.

[0047] To address the issue of inaccurate angiography caused by internal and external rotation of the patient's lower limbs, this embodiment also includes a heel support 2. The heel of the heel support 2 is inserted into the lower limb plate 1 via a rod and fixed by a snap-fit ​​mechanism (this is prior art and not shown in the figure). In this embodiment, the lower limb plate 1 has multiple grooves (not shown in the figure) near the end of the heel support 2 for inserting the rod of the heel support 2. These grooves are distributed along the arc direction. If only a single lower limb needs to be fixed, the two lower limb plates 1 are combined to form a U-shaped knot, and the heel support 2 is then inserted into the groove closest to the bottom and secured.

[0048] Working principle: When it is necessary to position and fix the patient's two lower limbs, place the two lower limbs on the lower limb plates 1 respectively. By adjusting the distance and swing angle between the lower limb plates 1, and then binding the fixing strap 6 to the corresponding felt surface 13, the positioning and fixation can be achieved. If only a single lower limb needs to be positioned and fixed, rotate and remove the fixing rod 12, then rotate the lower limb plate 1 so that the through hole 9 of the arc plate 10 closest to the other lower limb plate 1 aligns with the through hole 9 on the limiting block 11. Then insert the fixing rod 12 and rotate again, so that the sides of the two lower limb plates 1 fit together, forming a U-shaped fixing structure. Then adjust the length of the fixing strap 6 and attach it to the Velcro 5 to fix the patient's single lower limb support. To prevent the patient's lower limb from rotating, the rod of the heel support 2 can be inserted into the groove at the bottom of the U-shaped section, so that the foot of the lower limb to be tested can be placed in the heel support 2.

[0049] Example 2: A positioning and fixation device for lower extremity radiographic imaging, such as...Figure 6 As shown, the main difference between this embodiment and embodiment 1 lies in the position of the connecting rod 4, the structure of the connecting rod 4, and the specific structure of the corresponding connecting mechanism.

[0050] In this embodiment, a side cavity 18 is formed inside the connecting rod 4. The connecting mechanism mainly consists of a sleeve 15, a rotating rod 17, two sets of limiting devices, a cylindrical body 22, a rotating rod 16, and a piston 20. Figure 8 and Figure 9 As shown, the end of the rotating rod 17 is rotatably connected to the end of the lower limb plate 1, allowing the lower limb plate 1 to swing horizontally and the sides of the two lower limb plates 1 to fit together. The sleeve 15 is fitted onto the rotating rod 17, and a limiting ring is provided on the side wall of the rotating rod 17. The limiting ring is also located inside the sleeve 15 and rotatably connected to the sleeve 15, allowing the rotating rod 17 to rotate stably. Under the limitation of the side cavity 18, the sleeve 15 can only translate along its length. A sealing cavity 23 is opened inside the sleeve 15 near the side cavity 18. One end of each of the two limiting devices is located inside the sealing cavity 23, and the other end contacts the inner side wall of the rotating rod 17 and the connecting rod 4, respectively. The limiting device mainly consists of a sliding rod 21 and a contact plate 19, as shown... Figure 9 As shown, the two contact plates 19 are located near the inner walls of the rotating rod 17 and the connecting rod 4, respectively, and the other end of the sliding rod 21 is located inside the sealing cavity 23. One end of the cylindrical body 22 is inserted into the sealing cavity 23 of the sleeve 15, combined with... Figure 7 The other end of the cylindrical body 22 passes through the through groove 14 and is located outside the connecting rod 4. The piston 20 is slidably disposed inside the cylindrical body 22, and the end of the rotating rod 16 is rotatably connected to the piston 20. The side wall of the rotating rod 17 is also threadedly connected to the inner side wall of the cylindrical body 22. Thus, when the rotating rod 16 is rotated, the piston 20 slides towards one side of the sealing cavity 23, compressing the space of the sealing cavity 23, so that the two abutment plates 19 are tightly fitted against the inner side wall of the connecting rod 4 and the end of the rotating rod 17, thereby achieving a fixing effect. The sealing cavity 23 can be filled with gas or liquid. If it is liquid, the liquid needs to be filled into the entire sealing space so that the piston 20 moves upward, and the abutment plates 19 can be pushed out by utilizing the incompressible property of the liquid. If the gas is a compressible fluid, after the contact plate 19 contacts both the connecting rod 4 and the rotating rod 17, the piston 20 continues to be pushed downwards, increasing the air pressure in the sealed space. This increases the static friction between the contact plate 19 and the rotating rod 17, thereby improving the fixing effect.

[0051] To address the issue of inaccurate angiography caused by internal or external rotation of the patient's lower limbs, this embodiment incorporates a second groove 30 along the length of the side wall of the connecting rod 4. Figure 10As shown, a rotating mechanism is installed in the second slide groove 30 to control the angle of the support 2. The rotating mechanism mainly consists of a second slider 25, a limiting plate 27, a rotating plate 28, a push rod 29, and a knob 24. The second slider 25 is slidably installed in the second slide groove 30, combined with... Figure 11 As shown, an L-shaped cavity 26 is opened inside the slider 25; the rotating plate 28 is rotatably connected to the slider 25, and the end of the rotating plate 28 is fixedly connected to the support 2; one end of the push rod 29 and the limiting plate 27 are both located inside the cavity 26, and the protruding positions of the push rod 29, the limiting plate 27, and the side wall of the cavity 26 form a sealed space. The other end of the push rod 29 is located outside the slider 25 and is fixedly connected to the knob 24, and the side wall is threadedly connected to the slider 25; the limiting plate 27 is in contact with the rotating plate 28. In this way, after the medical staff adjusts the rotation angle of the support 2, they rotate the knob 24, and the push rod 29 moves downward. Under the action of the fluid, it pushes the limiting plate 27 to make tight contact with the rotating plate 28, thereby fixing the angle. This principle is the same as the fixing principle of the sleeve 15 mentioned above, both of which require the injection of fluid into the cavity 26. The fluid can be liquid or gas.

[0052] In addition, for easy disassembly of the heel support 2, such as Figure 6 As shown, the second groove 30 runs through the entire length of the connecting rod 4, with openings at both ends. This allows the support 2 to be removed and replaced simply by moving it to the sides.

[0053] In this embodiment, if only a single lower limb needs to be fixed, simply rotate the lower limb plate 1 so that it rotates around the rotating rod 17, causing its sides to fit together, thereby forming an overall structure with a U-shaped cross-section. Then, attach the fixing strap 6 and the felt 13 to achieve the fixing effect.

[0054] It should be noted that the connecting rod 4 is located on the back of the lower limb plate 1 or at the heel of the heel support 2, both of which are within the scope of protection of this patent. At the same time, as long as the connecting mechanism can control the rotation and movement of the lower limb plate 1, so that the two lower limb plates 1 can be combined to fix a single lower limb, the structural design of such a connecting mechanism is also within the scope of protection of this patent.

[0055] Working principle: In this embodiment, the method of fixing the patient's two legs and one leg is the same as in embodiment 1. However, in this embodiment, after the position of the lower limb plate 1 is fixed, the rotating rod 16 is rotated clockwise, causing the piston 20 to move upward, thereby compressing the sealing space. This causes the sliding rod 21 and the contact plate 19 to move to both sides of the sealing cavity 23. Finally, the two contact plates 19 are tightly contacted with the inner walls of the rotating rod 17 and the connecting rod 4, respectively, thereby fixing the lower limb plate 1. When adjusting the angle of the heel support 2, the knob 24 is rotated, causing the push rod 29 to move downward. Under the action of the fluid, the limiting plate 27 is tightly contacted with the rotating plate 28, thereby fixing the rotation angle of the heel support 2.

[0056] Example 3: A positioning and fixation device for lower extremity radiographic imaging. The main structure of this example is the same as that of Example 2, the main difference being the arrangement of the fixation straps 6. Figure 12 As shown, in this embodiment, the use of Velcro 5 is eliminated. Different felt surfaces 13 are provided on the same horizontal plane on both sides of the back of the lower limb plate 1. Multiple fixing straps 6 are provided on the front of the lower limb plate 1, and the fixing straps 6 correspond to the horizontal positions of the felt surfaces 13. When it is necessary to position and fix a patient's single lower limb, the lower limb plate 1 is rotated to... Figure 13 At the position shown, attach the fixing strap 6 to the fleece surface 13 on the back of the other lower limb plate 1 to achieve fixation.

[0057] It should also be noted that the arrangement of the fixing strap 6 and the fleece 13 in this embodiment can still achieve the effect of fixing the lower limbs when the two lower limb plates 1 are combined to form a U-shaped cross section.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
