Description

Technical Field

[0001] This invention relates to the field of postoperative care devices, and in particular to an adjustable lower limb flap transplantation postoperative auxiliary fixation support device. Background Technology

[0002] Skin flap transplantation is a surgical technique that uses skin and subcutaneous tissue with its own blood supply to repair defects. It is divided into pedicled flaps and free flaps. Pedicled flaps maintain blood supply through the pedicle and are temporarily nourished by the pedicle after transfer. Once blood vessels grow into the recipient wound and a new blood supply is established, the pedicle is severed (except for local flaps and island flaps). Free flaps reconstruct blood supply through microsurgical anastomosis of blood vessels and are suitable for organ reconstruction, repair of penetrating defects, etc.

[0003] For patients who have undergone lower limb flap transplantation, the surgical site needs to be bandaged after the flap transplantation is completed. In order to avoid the flap from necrosis due to pressure, the lower limb needs to be suspended in the air and supported by appropriate auxiliary devices.

[0004] It should be noted that the Chinese utility model patent with patent number ZL202122300065.6 and patent name, entitled "A Multifunctional Lower Limb Support Pad for Medical Orthopedics," essentially discloses a lower limb auxiliary support device. This lower limb auxiliary support device is applicable to patients who require suspension after surgery in the posterior skin graft area and flap transplantation area of ​​the lower leg. Specifically, the multifunctional lower limb support pad for medical orthopedics discloses the following technical solution: A multifunctional lower limb support pad for medical orthopedics includes a support pad body, which includes a base plate, an insertion part, a leg support part, and a foot support part. A receiving groove is provided on the top left side of the base plate. The insertion part is located on the top right side of the base plate. The leg support part is located in the middle of the top of the base plate and is detachable. The foot support part is located on the top left side of the base plate. When the leg support part is detached from the top of the base plate, the patient's lower leg can be suspended.

[0005] However, the aforementioned medical orthopedic multifunctional lower limb support pad still has the following shortcomings, specifically: Defect 1: For patients who have undergone lower leg flap transplantation, although this medical orthopedic multifunctional lower limb support pad can provide suspended auxiliary support for the patient's lower leg, it cannot move with the patient's leg. In actual use, the patient is forced to maintain a designated position for a long time, which restricts the patient's physical activity and results in poor comfort. Defect 2: This medical orthopedic multifunctional lower limb support pad is only suitable for patients whose lower leg skin flap is located on the posterior side (i.e., skin grafting on the posterior side of the lower leg). For patients whose lower leg skin flap is located on the left, right, or anterior side, there is still a risk that the blanket will compress the skin flap. In other words, this medical orthopedic multifunctional lower limb support pad has poor applicability. Defect 3: Different patients have different body shapes and different lower leg lengths. This medical orthopedic multifunctional lower limb support pad cannot be adaptively adjusted according to the lower leg length or skin flap position, resulting in poor adjustability and poor adaptability.

Detailed Implementation

[0028] The present invention will now be described in conjunction with specific embodiments.

[0029] Example 1, as Figures 1 to 3 As shown, an adjustable lower limb flap transplantation postoperative auxiliary fixation support device includes a support body, which includes a thigh binding component 1 and a lower leg support and protection component 2 located at the front end of the thigh binding component 1.

[0030] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 as well as Figure 7 As shown, the thigh binding assembly 1 includes a left fixing plate 11 and a right fixing plate 12, which are respectively curved in an arc shape. The left fixing plate 11 and the right fixing plate 12 are arranged facing each other. The upper end of the left fixing plate 11 is connected to the upper end of the right fixing plate 12 through an upper Velcro strap 13, and the lower end of the left fixing plate 11 is connected to the lower end of the right fixing plate 12 through a lower Velcro strap 14. The left fixing plate 11 has a left rear end hinge portion 15 that protrudes forward in the middle, and the right fixing plate 12 has a right rear end hinge portion 16 that protrudes forward in the middle. The left rear end hinge portion 15 and the right rear end hinge portion 16 are arranged facing each other.

[0031] It should be explained that in this embodiment, the left fixing plate 11 and the right fixing plate 12 can be made of rigid plastic, and the left rear hinge portion 15 and the left fixing plate 11 are injection molded into an integral structure, as are the right rear hinge portion 16 and the right fixing plate 12. Of course, the aforementioned rigid plastic material does not constitute a limitation on this embodiment; that is, the left fixing plate 11 and the right fixing plate 12 in this embodiment can also be made of other materials, such as aluminum, stainless steel, etc.

[0032] Furthermore, such as Figures 1 to 5As shown, the calf support and protection assembly 2 includes a front support block and a rear support block 22 arranged opposite each other and spaced apart. The upper end of the front support block has a front positioning groove 211, and the front positioning groove 211 is equipped with a front Velcro strap 23 for securing the lower end of the patient's calf or ankle during use. The upper end of the rear support block 22 has a rear positioning groove 221. The rear surface of the rear support block 22 is provided with a left front hinge 222 corresponding to the left rear hinge 15 and a right front hinge 223 corresponding to the right rear hinge 16. The left front hinge 222 is hinged to the left rear hinge 15 via a left pivot 31. 223 is hinged to the right rear end hinge part 16 via the right pivot 32; an auxiliary support block 24 is installed between the front support block and the rear support block 22. The auxiliary support block 24 has a clearance groove 241 that runs through the front and rear direction and opens upward. The rear support block 22 is fixedly installed with two sleeves 25 that are symmetrically arranged on the left and right sides of the rear positioning groove 221 and extend forward in a straight line. The front end of each sleeve 25 is fixedly connected to the auxiliary support block 24 and the front end of each sleeve 25 extends to the front end side of the auxiliary support block 24. The front support block is fixedly installed with a rod 26 that extends backward in a straight line corresponding to each sleeve 25. Each rod 26 is inserted into the corresponding sleeve 25.

[0033] It should be explained that the front support block, the rear support block 22, and the auxiliary support block 24 are all made of rigid plastic. The left front hinge 222, the right front hinge 223, and the rear support block 22 are injection molded into an integral structure. Of course, the above materials do not constitute a limitation on this embodiment. That is, the front support block, the rear support block 22, and the auxiliary support block 24 of this embodiment can also be made of other materials.

[0034] Furthermore, such as Figures 1 to 5 As shown, the front support block, rear support block 22, and auxiliary support block 24 are each equipped with an "n"-shaped protective member 27, and each protective member 27 has a downwardly protruding pin 271 at both ends. The upper surfaces of the front support block, rear support block 22, and auxiliary support block 24 each have two insertion holes 28, and the pins 271 of each protective member 27 are inserted into the insertion holes 28 of the corresponding front support block, rear support block 22, and auxiliary support block 24. It should be noted that each protective member 27 is made of rigid plastic, and each pin 271 is injection molded integrally with the corresponding protective member 27. Of course, the above materials do not constitute a limitation on this embodiment; that is, the protective member 27 of this embodiment can also be made of other materials.

[0035] The following is a detailed description of the adjustable lower limb flap transplantation postoperative auxiliary fixation support device in this embodiment, with specific usage steps included: Step a: Adaptively adjust the position of the support body according to the patient's knee joint position so that the left pivot 31 and the right pivot 32 are aligned with the patient's knee joint; Step b: After the support body is properly adjusted, the left fixing plate 11 and the right fixing plate 12 are connected and fixed by the upper Velcro strap 13 and the lower Velcro strap 14. At this time, the left fixing plate 11 and the right fixing plate 12 cooperate and clamp the patient's thigh so that the entire thigh binding assembly 1 is installed and fixed on the outside of the patient's thigh. Step c: Place the upper part of the patient's lower leg into the rear positioning groove 221 of the rear support block 22 to position the upper part of the patient's lower leg. Adjust the position of the front support block by moving it back and forth according to the length of the patient's lower leg so that the lower part of the patient's lower leg or ankle falls into the front positioning groove 211 of the front support block. The front positioning groove 211 can position the lower part of the patient's lower leg or ankle. At this time, the auxiliary support block 24 is located below the middle of the patient's lower leg and the middle of the patient's lower leg falls into the clearance groove 241 of the auxiliary support block 24. The clearance groove 241 can keep the auxiliary support block 24 away from the middle of the patient's lower leg, thereby ensuring that the middle of the patient's lower leg is suspended when supported. Step d: After the front support block is properly adjusted and the patient's lower leg or ankle falls into the front positioning groove 211, fasten the front Velcro strap 23 to the lower leg or ankle of the patient to achieve the installation and fixation of the front support block. Step e: After the front support block is installed and fixed, insert each protective component 27 into the front support block, the rear support block 22 and the auxiliary support block 24 respectively. The pins 271 of each protective component 27 are inserted into the corresponding holes 28 of the support block. That is, each protective component 27 is installed on the corresponding support block by plugging. At this time, each protective component 27 is located on the front side of the patient's lower leg and is away from the patient's lower leg.

[0036] It should be emphasized that the support body in this embodiment is fixed by the thigh binding assembly 1 and the front Velcro strap 23 on the front support block, meaning the entire support body can move adaptively with the patient's leg. Since the hinge between the thigh binding assembly 1 and the rear support block 22 is aligned with the patient's knee joint, the thigh binding assembly 1 and the rear support block 22 can also rotate adaptively when the patient's knee joint moves. Therefore, the adjustable lower limb flap transplantation postoperative auxiliary fixation support device of this embodiment can adapt to the patient's leg movements. During use, the patient is not forced to maintain a specific position for extended periods, thus limiting their physical activity. Compared to existing technologies, the adjustable lower limb flap transplantation postoperative auxiliary fixation support device of this embodiment offers better comfort.

[0037] It should be further emphasized that, in the process of protecting the lower leg from pressure after lower limb flap transplantation with the lower leg support and protection component 2 in this embodiment, multiple protective components 27 block the blanket on the front side of the patient's lower leg, the combination structure composed of two sleeves 25 and two inserts 26 blocks the blanket on the left and right sides of the patient's lower leg, and the lower ends of the front support block 22, the rear support block 22, and the auxiliary support block 24 block the blanket on the rear side of the patient's lower leg, thus suspending the lower leg. Therefore, the movable adjustable lower limb flap transplantation postoperative auxiliary fixation support device in this embodiment can provide all-round pressure protection for the patient's lower leg, that is, it can be effectively applied to patients whose lower leg flap is located on the left, right, front, or back side. Compared with the prior art, this embodiment has stronger applicability.

[0038] It should be noted that each protective component 27 in this embodiment is installed on the corresponding support block in a detachable manner, and the protective component 27 is selectively used; for patients whose lower leg flap is located on the posterior side, the protective component 27 can be directly removed from the corresponding support block.

[0039] Furthermore, during the use of the adjustable lower limb flap transplantation postoperative auxiliary fixation support device in this embodiment, each insertion rod 26 can slide within the corresponding sleeve 25, and the position of the anterior support block can be adaptively adjusted according to the length of the patient's lower leg. That is, this embodiment can adaptively adjust the position of the anterior support block according to the length of the patient's lower leg or the position of the flap. Compared with the prior art, this embodiment has better adjustability and stronger adaptability.

[0040] In summary, the adjustable lower limb flap transplantation postoperative auxiliary fixation support device of this embodiment has the advantages of novel structural design, good user comfort, strong applicability and good adjustability, thanks to the above structural design.

[0041] Example 2, as Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that: one end of the auxiliary support block 24 is screwed with a rod locking handle screw 291, the threaded part of the rod locking handle screw 291 extends into the inner hole of the sleeve 25 at the corresponding position, and the threaded part of the rod locking handle screw 291 abuts against the rod 26 at the corresponding position.

[0042] The other end of the auxiliary support block 24 is screwed with a pin-locking handle screw 292. The threaded part of the pin-locking handle screw 292 extends into the corresponding position insertion hole 28, and the threaded part of the pin-locking handle screw 292 abuts against the pin 271 of the corresponding protective part 27.

[0043] It should be noted that by locking the handle screw 291 with the plug rod, this embodiment 2 can achieve a relatively fixed state between the plug rod 26 and the sleeve 25 during use, thereby ensuring that the position between the front support block and the rear support block 22 is relatively fixed, so as to avoid the front support block from shifting due to the loosening of the front Velcro strap 23 during use.

[0044] Furthermore, the protective component 27 is locked and fixed to the auxiliary support block 24 by the handle screw 292 with a pin to prevent the protective component 27 on the auxiliary support block 24 from slipping off and falling off during use, thereby improving the stability and reliability of use.

[0045] In addition, the plug locking handle screw 291 and the pin locking handle screw 292 have the advantages of convenient and quick tightening and loosening operation.

[0046] Example 3, as Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the difference between this embodiment 3 and embodiment 1 is that: the front support block and the rear support block 22 are respectively screwed with pin locking handle screws 292 that extend into the corresponding insertion holes 28, and the threaded rod of each pin locking handle screw 292 abuts against the pin 271 of the corresponding protective part 27.

[0047] The protective component 27 is locked and fixed to the front support block and the rear support block 22 by means of a pin and a handle screw 292, so as to prevent the protective component 27 on the front support block and the rear support block 22 from slipping off and falling off during use, thereby improving the stability and reliability of use.

The left soft rubber pad 17 and the right soft rubber pad 18 are silicone pads.

[0049] When the thigh binding assembly 1 is installed and fixed to the outside of the patient's thigh, the left fixation plate 11 contacts the patient's thigh through the left soft rubber pad 17, and the right fixation plate 12 contacts the patient's thigh through the right soft rubber pad 18. The left soft rubber pad 17 and the right soft rubber pad 18 can effectively reduce the pressure sores that occur when the left fixation plate 11 and the right fixation plate 12 are bound.

[0050] Example 5, such as Figure 6 and Figure 7 As shown, the difference between this fifth embodiment and the first embodiment is that the upper and lower ends of the left fixing plate 11 and the upper and lower ends of the right fixing plate 12 are respectively provided with connecting parts 19, and each connecting part 19 of the right fixing plate 12 is provided with a connecting hole 191.

[0051] The fixed end of the upper hook and loop fastener 13 is installed on the connecting part 19 at the upper end of the left fixing plate 11. The free end of the upper hook and loop fastener 13 passes through the connecting hole 191 at the upper end of the right fixing plate 12 and is folded back. The free end of the upper hook and loop fastener 13 is fastened to the part of the upper hook and loop fastener 13 located between the left fixing plate 11 and the right fixing plate 12 through the hook and loop fastener structure.

[0052] In addition, the fixed end of the lower hook and loop fastener 14 is installed at the connecting part 19 at the lower end of the left fixing plate 11, and the free end of the lower hook and loop fastener 14 passes through the connecting hole 191 at the lower end of the right fixing plate 12 and is folded back. The free end of the lower hook and loop fastener 14 is fastened to the part of the lower hook and loop fastener 14 located between the left fixing plate 11 and the right fixing plate 12 through the hook and loop fastener structure.

[0053] Example 6, as Figure 5 As shown, the difference between this embodiment six and embodiment one is that: the front support block has a protrusion 212 on the bottom surface of the front positioning groove 211, and the protrusion 212 has a through hole 2121 that runs through the left and right directions.

[0054] The front Velcro strap 23 passes through the through hole 2121 of the protrusion 212, and the two ends of the front Velcro strap 23 are fastened together by the Velcro structure.

[0055] Example 7 differs from Example 1 in that the upper Velcro strap 13, the lower Velcro strap 14, and the front Velcro strap 23 are all elastic straps.

[0056] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
