Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a calcaneal radiograph retention device. Background Art

[0002] A calcaneal radiograph is a common medical examination used to evaluate the condition of the calcaneus (the bone in the heel). This examination is usually performed using an X-ray or CT scan. A calcaneal radiograph can help doctors diagnose a variety of problems, including calcaneal fractures, bone spurs (bone hyperplasia), calcaneal osteomyelitis, arthritis, and more. Through the examination, doctors can learn about the structure and density of the calcaneus, as well as whether there are any abnormal changes. When performing a calcaneal X-ray, doctors will examine different angles as needed, such as the front, side, or oblique position.

[0003] Clinically, the patient's conventional body position cannot capture the full length of the calcaneus, or it may overlap with other bones in the heel, resulting in double images or unclear images, especially in heel surgery where a comprehensive image of the calcaneus is required. When taking an X-ray, medical staff will use their hands to lift the foot near the toes and move it upward in order to clearly capture the image of the heel bone. However, this method can easily expose medical staff to radiation and pose a safety hazard. Summary of the invention

[0036] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment, this embodiment provides a calcaneal radiograph retention device, such as Figure 3 and Fig.11As shown, it includes a wrapping belt 4, which is wrapped around and bound on the toes of the foot; the specific structure of the wrapping belt 4 is: the wrapping belt 4 includes a horizontal end and wrapping ends bent and extended at both ends of the horizontal end, one of the wrapping ends is a insertion plug, and the other wrapping end is provided with an insertion hole, and the insertion plug passes through the insertion hole and is adhered to the side wall of the insertion hole opening through Velcro.

[0038] Locking member 2, such as Figure 4 and Figure 5 As shown, both side walls of the locking member 2 are provided with straps 1, and the two straps 1 are extended and bound along the circumference of the leg, and the two straps 1 are adhered to each other by Velcro to fix the locking member 2 on the calf. One end of the locking member 2 extends downward to form a vertical supporting end, and the supporting end enhances the supporting strength vertically; the other end of the locking member 2 is bent and extends in the horizontal direction to form an extended end, and a locking end 21 is provided on the upper side of the extended end, and a reversing channel is provided between the bottom end of the locking end 21 and the upper end of the extended end, and a locking groove is provided on the upper end surface of the locking end 21, and a fixing head 22 is detachably inserted in the locking groove. A traction belt 3, a connecting buckle 41 is provided on the outer side wall of one of the winding ends, and an annular structure is provided at both ends of the traction belt 3, and the annular structure at one end of the traction belt 3 passes from one side of the connecting buckle 41 to the other side, and the annular structure at the other end of the traction belt 3 passes through the annular structure passing through the connecting buckle 41 and is tightened, as shown in FIG. Fig.10 As shown. The annular structure at one end of the traction belt 3 away from the connecting buckle 41 passes through the reversing channel, and is pulled upward along the side wall of the locking end 21 to the upper end of the locking end 21, and then the annular structure is pulled in the reverse direction to tighten the traction belt 3. The extension end and the supporting end form an inverted L-shaped structure with good support strength, and the locking end 21 is set away from the supporting end to extend the support force arm, which is convenient for traction and force application of the traction belt 3.

[0039] The retaining member is composed of a wrapping belt 4 wrapped and fixed on the toes of the foot, a locking member 2 fixed on the calf, and a traction belt 3. An I-shaped guide wheel 23 is rotatably arranged in the annular channel, a notch is arranged on the side wall of the locking groove, and a matching shaft is rotatably arranged in the notch. The traction belt 3 passing through the annular channel passes from below the I-shaped guide wheel 23, and is pulled upward along the side wall of the locking end 21 and around the upper side wall of the matching shaft. One end of the traction belt 3 is connected to the wrapping belt 4, and the other end of the traction belt 3 passes through the reversing channel, and is pulled upward along the side wall of the locking end 21 to the upper end of the locking end 21 and then reversely tensioned. The wrapping belt 4 is pulled synchronously with the toes by the traction force of the traction belt 3, thereby adjusting the angle between the instep and the calf.

[0040] After the wrapping belt 4 pulls the toes to stretch and change the toe extension angle, the traction belt 3 needs to be fixed. Here, there are gaps between the side walls of the fixed head 22 on both sides and the two sides in the locking groove, that is, after the fixed head 22 is inserted into the locking groove, there are gaps between the two long side walls of the fixed head 22 and the inner wall of the locking groove, and the two short side walls of the fixed head 22 slide and fit with the corresponding side walls in the locking groove, and the width of the gap is less than the thickness of the traction belt 3. Here, the traction belt 3 adopts a medical non-woven fabric or fiber braided belt with a flat structure. After the traction belt 3 is pulled, the fixed head 22 is placed on the traction belt 3 located at the notch position of the locking groove, and pressed down with force. The traction belt 3 is located at both sides of the notch of the locking groove and follows the pressed fixed head 22 to be pulled into the locking groove. The side walls of the traction belt 3 are squeezed in the gap with a width less than the thickness of the traction belt 3. The traction belt 3 is squeezed to produce compression deformation, and the friction between the outer wall of the fixed head 22 and the inner wall of the locking groove is enhanced. In the case of no external force pulling the fixed head 22, the fixed head 22 will not be easily detached. At the same time, the traction belt 3 is clamped in the gaps on both sides of the fixing head 22 with a double-layer structure, which is equivalent to a double-layer fixing structure, further enhancing the stability of the traction belt 3 being locked in the locking groove.

[0041] It should be noted that since the muscles between the foot and the calf have corresponding stretching capabilities, after the traction belt 3 pulls the toes to stretch and drives the entire instep to change its angle, it can continue to make small angle adjustments. Therefore, the advantage of using the fixed head 22 to press the traction belt 3 down along the notch of the locking groove to embed the traction belt 3 into the locking groove is that the position of the traction belt 3 after traction is kept stationary. As the fixed head 22 continuously pushes the traction belt 3 into the locking groove, the part of the traction belt 3 located on the side of the notch of the locking groove can be further pulled into the locking groove, which is conducive to further pulling the instep angle to change.

[0042] The fixation method for calcaneal X-ray using fixation devices is as follows:

[0043] like Figure 1As shown, first, the horizontal end of the wrapping belt 4 is located at the lower side of the toes, and the two wrapping ends are respectively wrapped around the big toe and the little toe, and are stretched and bonded together on the upper side, so that the wrapping belt 4 is wrapped around the toes of the foot, and the locking member 2 is fixed on the calf. One end of the traction belt 3 is connected to the wrapping belt 4, and the other end of the traction belt 3 passes through the reversing channel, and is pulled upward along the side wall of the locking end 21 to the upper end of the locking end 21 and then reversely tensioned, and the traction belt 3 is clamped in the gap on both sides of the fixed head 22 with a double-layer structure. The wrapping belt 4 is pulled synchronously by the traction force of the traction belt 3 to reduce the angle between the instep and the calf. Change the patient's normal body position to avoid the heel overlapping with other bones, ensure that the full length of the calcaneus can be clearly photographed, and avoid ghosting or unclear images when taking the film. The wrapping belt 4 here can be made of disposable medical non-woven fabric, which will be treated as medical waste after the filming, and other parts of the retaining part are disinfected with alcohol for reuse. And, as Fig.11 As shown, a stuffing pad 42 for contacting the toe gap between two adjacent toes may also be provided on the horizontal end. The stuffing pad 42 is tilted and supported in the toe gap, which is beneficial to anti-slip and prevents the wrapping belt 4 from being separated from the toes.

[0044] Of course, patients may need to adopt different postures to ensure the clarity and accuracy of the image. For example, the patient may need to lie on his back on the examination bed with his legs straight so that his knees are in a straight line. The doctor may also ask the patient to adjust the position of the ankle joint, such as excessive dorsiflexion, in order to better capture the axial position of the calcaneus. Regardless of the detection posture, the above-mentioned retaining parts can be used to tilt the foot near the toes upward to ensure that the entire length of the calcaneus is captured clearly. At the same time, there is no need for medical staff to use their hands to assist in tilting and tilting the foot near the toes upward to avoid radiation exposure to medical staff.

[0045] In addition to being used for fixing calcaneal X-rays, the above-mentioned retaining piece can also flatten the sole of the foot for fixation and later rehabilitation of bone or ligament injuries in the ankle. After an ankle injury, especially when it involves a fracture or ligament injury, the anatomical structure of the foot may change, resulting in foot deformation or instability. Flattening the sole of the foot can ensure that the various parts of the foot remain in the correct position, which helps to restore the normal function of the foot. Secondly, after an injury, swelling and pain in the ankle may make it difficult for the patient to bear the weight of the foot. Flattening the sole of the foot can evenly distribute the weight of the foot, reduce pressure on the injured part, and thus relieve pain and swelling. In addition, blood circulation in the ankle may be affected, resulting in local ischemia and hypoxia. Flattening the sole of the foot can promote blood return to the injured part, accelerate metabolism and waste discharge, and facilitate the repair and regeneration of injured tissue.

[0046] The method of using retainers to fix bone or ligament injuries in the ankle is:

[0047] like Figure 2 As shown, by changing the traction direction of the wrapping belt 4, the horizontal end of the wrapping belt 4 is located on the upper side of the toes, and the two wrapping ends are respectively wrapped around the outside of the big toe and the little toe and stretched and adhered together on the lower side. The traction belt 3 is located in the space between the sole of the foot and the back of the calf. The wrapping belt 4 is tractioned downward by the traction belt 3 to synchronously pull the toes, thereby expanding the angle between the instep and the calf, stretching and flattening the sole of the foot, which helps to maintain the normal anatomical structure of the foot, reduce the pressure on the injured part, and help promote blood circulation in the injured part.

[0048] Further, in the first embodiment, the traction belt 3 is fixed in the locking groove: Figure 5 As shown, the traction belt 3 that follows the fixed head 22 and is embedded in the locking groove is resting between the fixed head 22 and the inner wall of the locking groove in a U-shaped structure. One side wall of the traction belt 3 fits with the side walls and bottom wall of the locking groove, and the other side wall of the traction belt 3 fits with the side walls of the fixed head 22. A large friction force is generated between the traction belt 3 and the inner wall of the locking groove and the outer wall of the fixed head 22, ensuring that the traction belt 3 is stably embedded in the locking groove and is not easy to fall off.

[0049] The second embodiment of the traction belt 3 being fixed in the locking groove: Figure 6 and Figure 7 As shown, winding notches 221 are provided on both side walls of the fixed head 22, and the traction belt 3 located at the notch position of the locking groove is wound on the outer side walls of the two winding notches 221, and the fixed head 22 is inserted into the locking groove, and the traction belt 3 is wound into a plurality of ring structures and embedded in the locking groove, so that the traction belt 3 is not easy to loosen. At the same time, the traction belt 3 located outside the winding notch 221 is clamped in the gap between the fixed head 22 and the inner wall of the locking groove, so that a large friction force is generated between the traction belt 3 and the inner wall of the locking groove and the outer wall of the fixed head 22, ensuring that the traction belt 3 is stably embedded in the locking groove and is not easy to fall off.

[0050] A third embodiment in which the traction belt 3 is fixed in the locking groove: Figure 8 and Fig. 9As shown, arc-shaped notches 223 are provided on both side walls of the fixed head 22, and a clamping notch 222 is provided on the bottom wall of the fixed head 22. Here, the fixed head 22 is made of elastic material, such as PVC plastic, as long as it has deformation characteristics. The traction belt 3 located at the notch position of the locking groove is embedded in the clamping notch 222, and arc-shaped protrusions 24 are fixed on both side walls in the locking groove. The fixed head 22 is inserted into the locking groove, and inclined surfaces are provided on the bottom walls of both sides of the fixed head 22. When the inclined surfaces contact the arc-shaped protrusions 24, the inclined surfaces on both sides of the clamping notch 222 will be squeezed together to clamp the traction belt 3, and the arc-shaped protrusions 24 will be embedded in the clamping notch 222 to prevent the fixed head 22 from escaping from the locking groove. At the same time, the traction belt 3 located on both sides of the clamping notch 222 is clamped in the gap between the fixed head 22 and the inner wall of the locking groove, so that a large friction force is generated between the traction belt 3 and the inner wall of the locking groove and the outer wall of the fixed head 22, ensuring that the traction belt 3 is stably embedded in the locking groove and is not easy to fall off.

[0051] A connecting rope is provided between the side wall of the fixing head 22 and the upper end of the locking end 21 to prevent the fixing head 22 from being lost.

[0052] Regardless of whether it is fixation of calcaneal radiography or fixation of bone or ligament injury of the ankle, the above three methods of fixation of the traction belt 3 in the locking groove are applicable.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
