Description

Technical Field

[0001] The utility model relates to an orthopedic medical device, in particular to a calcaneal bone traction and elevation pillow. Background Art

[0002] In the process of calcaneal traction treatment, a Brownian brace is usually used clinically to fix the patient's lower limbs and apply appropriate traction to correct the position of the calcaneus and create favorable conditions for fracture healing. Specifically, the Brownian brace is an adjustable metal support frame, usually installed at the end of the bed. When in use, the patient's legs need to be placed on the brace and raised at a certain angle.

[0003] In order to apply traction, clinicians need to first implant a Kirschner wire in the patient's calcaneal area. This is a special surgical nail that can be connected to an external traction system. The common practice is to install a U-shaped frame on the Kirschner wire, and the traction rope is tied to the U-shaped frame. By hanging weights or other counterweights on the traction rope, continuous and uniform traction can be applied to the patient's calcaneal area.

[0004] This treatment method of Brownian stent combined with Kirschner wire calcaneal traction has the advantages of relatively simple operation and low cost, so it is widely used in clinical practice. However, the Brownian stent also exposed some shortcomings during use. For example, due to the design characteristics of the stent, it is easy to cause problems such as local compression of the legs. In addition, the patient's legs are prone to external rotation posture during traction. This may not only affect the direction and size of the traction force and reduce the treatment effect, but also aggravate the discomfort of the patient's legs. In severe cases, it may even cause rotational abduction deformity of the hip or knee joint. Utility Model Content

[0053] The calcaneal bone traction and elevation pillow according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0054] Reference Figures 1 to 3 As shown, the calcaneal traction and elevation pillow provided according to the embodiment of the utility model includes a leg support seat 10 and a heel support seat 20.

[0055] Specifically, the leg support seat 10 has a leg support groove H101 suitable for placing the human calf, the leg support groove H101 extends along the length direction of the leg support seat 10, and the width of the leg support groove H101 is substantially equal to the width of the human calf.

[0056] The design of the leg support seat 10 is in accordance with the principle of ergonomics, and a leg support slot H101 is provided on the top surface thereof, and the leg support slot H101 extends along the length direction of the leg support seat 10. The width of the leg support slot H101 is substantially equal to the width of the human calf, and can well accommodate and fix the calf of the patient. Preferably, the inner wall of the leg support slot H101 is wrapped with a soft material, which can effectively prevent the patient's calf from being excessively squeezed locally, and can also provide necessary support, thereby ensuring that the patient can feel comfortable and relaxed when maintaining the treatment position for a long time.

[0057] The heel support seat 20 is detachably connected to one end of the leg support seat 10 in the length direction, and the heel support seat 20 has a heel support groove H201, which is connected with the leg support groove H101 to support the heel.

[0058] That is, the heel support seat 20 is designed with a heel support groove H201, which is connected with the leg support groove H101 on the leg support seat 10, and is used to accurately support the calcaneus of the patient. The geometric shape and size of the heel support groove H201 are adapted to the heel, and can well wrap the calcaneus area, so that the calcaneus remains in a proper state during the treatment process and avoids rotation or dislocation.

[0059] It is worth mentioning that the connection between the leg support 10 and the heel support 20 is detachable, which makes the use of the entire pillow more flexible and convenient. For example, in some cases, when only the patient's calf needs to be fixed, the medical staff can simply remove the heel support 20 and only use the leg support 10.

[0060] The material of the pillow can be high-strength and durable engineering plastics, with a solid structure that can withstand the wear and tear of long-term use. At the same time, the surface is smooth and burr-free, which is easy to clean and disinfect, reducing the risk of infection.

[0061] In actual use, medical staff only need to place the patient's calf and calcaneus in the leg bracket H101 and heel bracket H201 respectively, and adjust and connect the calcaneus traction device as needed to start traction treatment. At the same time, the patient's calf and calcaneus can be well supported and fixed, ensuring the effectiveness of the treatment.

[0062] The calcaneal traction and elevation pillow provided by the embodiment of the utility model adopts the leg support slot H101 and the heel support slot H201 design that fits the ergonomics, which can fix and support the patient's calf and calcaneal area more naturally and comfortably, avoiding the problem of local compression caused by the traditional Brownian support, and avoiding the external rotation of the lower limbs during traction, reducing the occurrence of Kirschner wires slipping outward, thereby greatly improving the patient's comfort and treatment experience. At the same time, the pillow structure is simple and practical, and the detachable design of the leg support seat 10 and the heel support seat 20 also facilitates adjustment and cleaning. For example, when the heel support is not needed, the heel support seat 20 can be removed, which is flexible and convenient to use. In addition, the overall operation is convenient and safe.

[0063] In one embodiment of the present invention, two side stoppers 101 are provided at one end of the leg support 10 close to the heel support 20. The two side stoppers 101 are respectively located on both sides of the width direction of the leg support slot H101 to limit the outward rotation of the sole of the foot to both sides.

[0064] In the embodiment, in order to further improve the fixation effect and prevent the patient from having problems such as external rotation of the legs during treatment, two side blocks 101 are added to one end of the leg support seat 10 close to the heel support seat 20. The two side blocks 101 are respectively located on both sides of the width direction of the leg support slot H101 and are symmetrically distributed.

[0065] When the patient's calf is placed in the leg support H101, the two side guards 101 are located on both sides of the patient's sole area. The main function of the side guards 101 is to limit the range of the patient's sole to rotate outward to both sides during treatment. Since the sole is limited by the side guards 101, even if the patient twists outward unconsciously, it will be blocked by the side guards 101 and the posture of the sole will be corrected in time. In this way, the patient's ankle and calf can be kept in a relatively neutral position, which not only avoids the medical risks caused by external rotation, but also reduces the patient's discomfort.

[0066] In addition, the side guard 101 can be covered with the same soft covering material as the leg support slot H101, which has appropriate cushioning properties and can play a good fixing role without causing pain or discomfort to the patient. In addition, the top of the side guard 101 adopts a progressive arc transition design, making its surface smooth and without edges and corners, which not only ensures comfort but also avoids potential injuries such as abrasions to the patient's skin.

[0067] In order to ensure the reliability of the structure and facilitate cleaning and disinfection, the side guard 101 and the leg support H101 are manufactured as a whole using an integrated molding process, and the structure is reliable and stable. In addition, there are no gaps and dead corners, and cleaning and disinfection are easy.

[0068] In one embodiment of the present invention, the heel bracket H201 is filled with a flexible filler to isolate and support the heel of the patient.

[0069] That is to say, the main function of the flexible filler is to isolate and support the patient's heel, ensuring that the calcaneus can be kept in a reasonable and comfortable position and state during treatment. The material selection of the flexible filler can be polyurethane foam or other foam plastics with good cushioning elasticity, which can not only provide the required support, but also absorb and disperse the pressure of the calcaneus area well to prevent local pressure sores.

[0070] In some embodiments of the present invention, the pillow further includes an adjustable base 30 , on which the leg support 10 and the heel support 20 are disposed, and the adjustable base 30 is configured to be able to adjust the heights of the leg support 10 and the heel support 20 .

[0071] That is, the adjustable base 30 is a structure that can be raised and lowered, and the leg support 10 and the heel support 20 are arranged on the adjustable base 30, so that the height can be adjusted. The base height can be continuously adjusted within a certain height range according to the needs, and the leg support 10 and the heel support 20 can be raised to a suitable traction treatment height, or lowered to a height close to the bed surface.

[0072] In this embodiment, the design of the adjustable base 30 allows the height positions of the leg support 10 and the heel support 20 to be flexibly adjusted. The leg support 10 and the heel support 20 can be raised to a suitable height according to clinical needs or individual differences of different patients. The height adjustment can be achieved through the adjustable base without the need for other auxiliary equipment. This personalized treatment posture adjustment helps to further optimize the treatment plan and meet individual differences.

[0073] In one embodiment of the present invention, the heel support groove H201 is formed as a semicircular groove, and the opening end of the semicircular groove faces the leg support seat 10 and communicates with the leg support groove H101.

[0074] The semicircular heel bracket H201 fits the natural curvature of the heel better and can provide maximum coverage and support for the calcaneus. When the patient's heel is placed, it can be completely embedded in the heel bracket H201, and the entire calcaneus area is evenly and firmly supported, thereby minimizing the displacement or rotation of the calcaneus. In addition, the semicircular heel bracket H201 has no edges and corners, which is more friendly to the heel and avoids potential injuries such as abrasions.

[0075] In one embodiment of the present invention, a positioning column is provided on one end surface of the heel support 20 facing the leg support 10 , and a positioning hole H102 suitable for being plugged into the positioning column is provided on the leg support 10 .

[0076] In order to further improve the connection stability and positioning accuracy between the heel support 20 and the leg support 10, the present embodiment adds a matching structure of a positioning column and a positioning hole H102 between the two. Specifically, a protruding cylindrical positioning column is provided on the end face of the heel support 20 close to the leg support 10. Correspondingly, a positioning hole H102 is provided at the end of the leg support 10, and the shape and size of the positioning hole H102 match the positioning column. The depth of the positioning hole H102 is moderate and can accommodate the positioning column to be fully inserted therein. During installation, it is only necessary to align the positioning column of the heel support 20 with the positioning hole H102 on the leg support 10, and then bring the two together and plug them in. The positioning column can accurately enter the positioning hole H102, thereby ensuring the alignment accuracy of the heel support 20 and the leg support 10 and preventing skewing or displacement.

[0077] The cooperation between the positioning column and the positioning hole H102 not only provides a positioning function, but also plays a role in fixed connection, so that the heel support 20 and the leg support 10 are firmly connected together. Preferably, the positioning column itself can be designed with an elastic snap-fit ​​structure. Once the positioning column is fully inserted into the positioning hole H102, it will automatically snap together, further enhancing the reliability of the connection. When disassembly is required, it is only necessary to apply a certain pulling force to the heel support 20 to overcome the snap-fit ​​effect and pull the positioning column out of the positioning hole H102. This process does not require the aid of tools and can be completed quickly by hand, greatly improving the efficiency of disassembly and assembly.

[0078] In one embodiment of the utility model, a plurality of first guide holes H103 are provided at the bottom of the leg support seat 10. The adjustable base 30 includes a bottom plate 301, a plurality of first threaded columns 302 and a plurality of first stop nuts 303, wherein the plurality of first threaded columns 302 are arranged at intervals on the bottom plate 301, and the plurality of first threaded columns 302 correspond to the plurality of first guide holes H103 one by one, and the upper end of each first threaded column 302 is slidably inserted into the corresponding first guide hole H103.

[0079] The multiple first stop nuts 303 correspond one by one to the multiple first threaded columns 302, and each of the first stop nuts 303 is threadedly mounted on the corresponding first threaded column 302 and stopped below the leg support seat, so that the leg support seat 10 can be supported at a predetermined height through the multiple first stop nuts 303.

[0080] That is to say, the position of each first threaded column 302 is precisely aligned with a first guide hole H103 at the bottom of the leg support. The number of first threaded columns 302 is equal to the number of first guide holes H103 to ensure that all first guide holes H103 can be matched with a first threaded column 302.

[0081] The material of the first threaded column 302 can be wear-resistant high-strength alloy steel. The lower end of the first threaded column 302 is firmly connected to the top plate of the adjustable base 30, and the length of the upper end is controlled to be able to completely pass through the corresponding first guide hole H103 and have an adjustment range that can slide up and down.

[0082] The thread of the first stop nut 303 matches the thread of the corresponding first threaded column 302. The first stop nut 303 is threadedly sleeved on the first threaded column 302, and a plurality of first stop nuts 303 at the same height can form a support plane, which is used to support the leg support seat 10 at a certain height.

[0083] When the height needs to be adjusted, it is only necessary to rotate each of the first stop nuts 303 in sequence so that each of the first stop nuts 303 is adjusted to another same height, thereby adjusting the leg support seat 10 to a new height position.

[0084] In this embodiment, the adjustable base 30 of the above structure greatly improves the convenience of use, and the height adjustment is convenient and simple. Moreover, this method of adjusting by screw thread can achieve continuous adjustment with high adjustment accuracy, and can be accurately locked to the required height according to clinical needs or patient needs. In addition, the structure is simple and reliable with good stability.

[0085] In another embodiment of the utility model, a plurality of second guide holes H202 are provided at the bottom of the heel support 20. The adjustable base 30 also includes a plurality of second threaded columns 304 and a plurality of second stop nuts 305, the plurality of second threaded columns 304 are arranged at intervals on the bottom plate 301, and the plurality of second threaded columns 304 correspond to the plurality of second guide holes H202 one by one, and the upper end of each second threaded column 304 is slidably penetrated into the corresponding second guide hole H202.

[0086] Multiple second stop nuts 305 correspond one-to-one to multiple second threaded columns 304, and each second stop nut 305 is threadedly mounted on the corresponding second threaded column 304 and stopped below the heel support 20, so that the heel support 20 is supported at a predetermined height by the multiple second stop nuts 305.

[0087] In this embodiment, on the adjustable base 30, in addition to the first threaded column 302 for adjusting the height of the leg support, a plurality of second threaded columns 304 corresponding to the second guide holes H202 are arranged at intervals. The position of each second threaded column 304 is precisely aligned with a second guide hole H202 at the bottom of the heel support 20, and the number is equal to the second guide holes H202. The material, size and other parameters of the second threaded column 304 are consistent with those of the first threaded column 302. The lower end of the second threaded column 304 is firmly connected to the bottom plate 301 of the adjustable base 30, and the length of the upper end is controlled to be able to completely pass through the second guide hole H202 and leave sufficient up and down travel.

[0088] Similar to the first threaded column 302, a second stop nut 305 matching with the first threaded column 302 is also provided on each second threaded column 304. The internal thread of the second stop nut 305 can be accurately sleeved on the external thread of the corresponding second threaded column 304, and can move up and down under the guidance of the second threaded column 304.

[0089] When the leg support seat needs to be adjusted, the heel support seat 20 also needs to be adjusted synchronously. Therefore, the first stop nut 303 and the second stop nut 305 can be screwed separately to adjust them to the same height position, thereby ensuring that the leg support seat and the heel support seat 20 are accurately supported at the said height position.

[0090] The design of the second threaded column 304 and the second stop nut 305 also has the advantages of convenient operation, precise adjustment, stable support, simple and reliable structure, etc.

[0091] Reference Figure 4 As shown, in some embodiments of the utility model, the leg support seat 10 includes a fixed seat 10b and a sliding support seat 10a, the fixed seat 10b is arranged on the adjustable base 30, and the fixed seat 10b is provided with a guide rail portion 101b, and the bottom of the sliding support seat 10a is provided with a sliding groove that slides with the guide rail portion 101b, so that the sliding support seat 10a can be slidably adjusted along the length direction of the leg support groove H101.

[0092] During use, according to the actual length of the patient's legs, the medical staff only needs to slide the sliding support 10a appropriately to adjust the effective length of the leg support 10 to match the patient's legs. Therefore, the structural design of the leg support 10 can achieve adjustment of the length of the leg support slot H101 within a certain range to meet the needs of different patients.
