Description

Technical Field

[0001] This utility model relates to the field of postoperative care device technology, and in particular to an auxiliary fixation device for lower limb flap transplantation. 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 flaps are located on the posterior side (i.e., skin grafts are placed on the posterior side of the lower leg). For patients whose lower leg skin flaps are 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 a poor pressure protection effect. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary fixation device for lower limb flap transplantation, which addresses the shortcomings of existing technologies. This auxiliary fixation device for lower limb flap transplantation has a novel structural design, good user comfort, and good protection against flap pressure.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0008] A postoperative auxiliary fixation device for lower limb flap transplantation includes a supporting main body; The support body includes a thigh binding assembly and a calf support and protection assembly located at the front end of the thigh binding assembly; The thigh binding assembly includes a left fixing plate and a right fixing plate arranged opposite each other and spaced apart. The left fixing plate and the right fixing plate are connected by a connecting strap, and the middle part of the left fixing plate and the middle part of the right fixing plate are respectively provided with a fixing plate hinge portion that protrudes forward. The lower leg support and protection assembly includes a front support block and a rear support block arranged in a front-to-back, spaced-apart configuration. The upper end of the front support block has a front positioning groove, and a support block strap for securing the lower end of the patient's lower leg or ankle is installed in the front positioning groove. The upper end of the rear support block has a rear positioning groove, and the rear surface of the rear support block has a support block hinge part corresponding to each fixing plate hinge part. Each support block hinge part is hinged to the corresponding fixing plate hinge part via a pivot. The front support block and the rear support block are connected by two protective rods symmetrically arranged on the left and right sides of the front positioning groove and the rear positioning groove.

[0009] The front support block and the rear support block are respectively equipped with "n"-shaped protective parts, and each protective part has a downward protruding pin at both ends. Two insertion holes are respectively opened on the upper surface of the front support block and the upper surface of the rear support block, and the pins of each protective component are respectively inserted into the insertion holes of the corresponding front support block and the rear support block.

[0010] The front support block and the rear support block are respectively screwed with locking handle screws that extend into the corresponding insertion holes, and the threaded part of each locking handle screw abuts against the pin of the corresponding protective component.

[0011] The inner walls of the left and right fixation plates are respectively equipped with soft rubber pads that come into contact with the patient's thigh during use.

[0012] The middle portions of the left fixing plate and the right fixing plate are respectively curved in an arc shape.

[0013] The connecting strap includes an upper hook and loop fastener and a lower hook and loop fastener.

Detailed Implementation

[0024] The present invention will now be described in conjunction with specific embodiments.

[0025] Example 1, as Figures 1 to 5 As shown, a postoperative auxiliary fixation device for lower limb flap transplantation includes a support body; the support body 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.

[0026] Specifically, such as Figures 1 to 4 As shown, the thigh binding assembly 1 includes a left fixing plate 11 and a right fixing plate 12 arranged opposite each other and spaced apart. The left fixing plate 11 and the right fixing plate 12 are connected by a connecting strap 13, and the middle of the left fixing plate 11 and the middle of the right fixing plate 12 are respectively provided with a fixing plate hinge portion 14 extending forward. It should be explained that the left fixing plate 11 and the right fixing plate 12 in this embodiment can be rigid plastic parts, and each fixing plate hinge portion 14 is injection molded integrally with the corresponding left fixing plate 11 and right fixing plate 12.

[0027] Furthermore, such as Figures 1 to 5As shown, the calf support and protection assembly 2 includes a front support block 21 and a rear support block 22 arranged opposite each other and spaced apart. The upper end of the front support block 21 has a front positioning groove 211, and a support block strap 23 for securing the lower end of the patient's calf or ankle is installed in the front positioning groove 211. The upper end of the rear support block 22 has a rear positioning groove 221, and the rear surface of the rear support block 22 is provided with support block hinge parts 24 corresponding to each fixing plate hinge part 14. Each support block hinge part 24 is hinged to the corresponding fixing plate hinge part 14 via a pivot 3. It should be noted that the front support block 21 and the rear support block 22 in this embodiment are both made of rigid plastic, and the support block hinge parts 24 and the rear support block 22 are injection molded into an integral structure.

[0028] Furthermore, such as Figures 1 to 5 As shown, the front support block 21 and the rear support block 22 are connected by two protective rods 25 symmetrically arranged on the left and right sides of the front positioning groove 211 and the rear positioning groove 221. Specifically, the front end of each protective rod 25 is fixedly connected to the rear surface of the front support block 21, and the rear end of each protective rod 25 is fixedly connected to the front surface of the rear support block 22. It should be explained that the protective rod 25 in this embodiment can be a hollow cylindrical structure. The hollow cylindrical structure of the protective rod 25 can effectively reduce the overall weight of the lower leg support protection component 2, thereby improving the overall portability of the auxiliary fixation device after lower limb flap transplantation in this embodiment.

[0029] The following is a detailed description of the auxiliary fixation device for lower limb flap transplantation in this embodiment, with reference to its specific usage process. The usage process includes the following steps: Step a: Adaptively adjust the position of the support body according to the patient's knee joint position so that pivot 3 is aligned with the patient's knee joint; Step b: After the support body is properly adjusted to the correct position, the left fixing plate 11 and the right fixing plate 12 are connected by the connecting strap 13 so that 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 through the rear positioning groove 221; place the lower part of the patient's lower leg or ankle into the front positioning groove 211 of the front support block 21, and secure the lower part of the patient's lower leg or ankle with the support block strap 23 to achieve the connection and installation of the front support block 21.

[0030] It should be emphasized that the support body in this embodiment is fixed by the thigh binding assembly 1 and the support block strap 23 on the front support block 21, 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 postoperative auxiliary fixation device for lower limb flap transplantation in this embodiment can move adaptively with 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 postoperative auxiliary fixation device for lower limb flap transplantation in this embodiment offers better comfort.

[0031] For the two protective rods 25 in this embodiment, they have the following functions: 1. Connect the front support block 21 and the rear support block 22 so that the front support block 21 and the rear support block 22 form a whole, thereby improving the structural stability of the lower leg support and protection assembly 2; 2. When the front support block 21 and the rear support block 22 support the patient's lower leg and suspend it in the air, the two protective rods 25 are located on the left and right sides of the patient's lower leg, respectively. At this time, the two protective rods 25 provide quilt protection on the left and right sides of the patient's lower leg.

[0032] In summary, the auxiliary fixation device for lower limb flap transplantation in this embodiment has the advantages of novel structural design, good user comfort, and good protection against flap pressure through the above structural design.

[0033] Example 2, as Figures 1 to 5 As shown, the difference between this embodiment 2 and embodiment 1 is that the front support block 21 and the rear support block 22 are respectively equipped with "n"-shaped protective parts 26, and each protective part 26 has a downward protruding pin 261 at both ends.

[0034] Two insertion holes 27 are respectively opened on the upper surface of the front support block 21 and the upper surface of the rear support block 22, and the pins 261 of each protective component 26 are respectively inserted into the insertion holes 27 of the corresponding front support block 21 and rear support block 22.

[0035] It should be noted that, in the process of protecting the lower leg from pressure by the blanket after the patient's lower limb flap transplantation, the lower leg support and protection component 2 in this embodiment has multiple protective components 26 blocking the blanket on the front side of the patient's lower leg, thereby further improving the protection effect of the flap from pressure.

[0036] In addition, each protective component 26 in this embodiment 2 is installed on the corresponding support block in a detachable manner, and the protective component 26 is selectively used; for patients whose lower leg flap is located on the posterior side, the protective component 26 can be directly removed from the corresponding support block.

[0037] Example 3, as Figures 1 to 5 As shown, the difference between this embodiment 3 and embodiment 2 is that: the front support block 21 and the rear support block 22 are respectively screwed with locking handle screws 28 that extend into the corresponding insertion holes 27, and the threaded part of each locking handle screw 28 abuts against the pin 261 of the corresponding protective part 26.

[0038] The protective component 26 is locked and fixed to the front support block 21 and the rear support block 22 by the locking handle screw 28, so as to prevent the protective component 26 of each support block from slipping off and falling off during use, thereby improving the stability and reliability of use.

[0039] Example 4, as Figures 1 to 5 As shown, the difference between this embodiment four and embodiment one is that the inner wall of the left fixation plate 11 and the inner wall of the right fixation plate 12 are respectively equipped with soft rubber pads 15 that come into contact with the patient's thigh during use.

[0040] When the thigh binding assembly 1 is installed and fixed to the outside of the patient's thigh, the left fixation plate 11 and the right fixation plate 12 respectively contact the patient's thigh through the soft rubber pad 15. The soft rubber pad 15 structure can effectively reduce the pressure sores that occur when the left fixation plate 11 and the right fixation plate 12 are bound.

[0041] It should be explained that the soft rubber pad 15 in this embodiment four can be a silicone pad.

[0042] Example 5, as Figures 1 to 4 As shown, the difference between this fifth embodiment and the first embodiment is that the middle part of the left fixing plate 11 and the middle part of the right fixing plate 12 are respectively curved in an arc shape.

[0043] Through the above-described shape design, this fifth embodiment can effectively improve the fit between the left fixation plate 11, the right fixation plate 12 and the patient's thigh, thereby improving the comfort during use.

[0044] Example 6, as Figures 1 to 4 As shown, the difference between this sixth embodiment and the first embodiment is that the connecting strap 13 includes an upper hook and loop fastener 131 and a lower hook and loop fastener 132. The upper end of the left fixing plate 11 is connected to the upper end of the right fixing plate 12 through the upper hook and loop fastener 131, and the lower end of the left fixing plate 11 is connected to the lower end of the right fixing plate 12 through the lower hook and loop fastener 132.

[0045] It should be noted that the upper Velcro strap 131 and the lower Velcro strap 132 are elastic straps.

[0046] When the left fixation plate 11 and the right fixation plate 12 are connected by the upper Velcro strap 131 and the lower Velcro strap 132, the upper Velcro strap 131 and the lower Velcro strap 132, which are elastic strap structures, enable the left fixation plate 11 and the right fixation plate 12 to elastically hold and clamp the patient's thigh, thereby improving the stability and reliability of the thigh binding assembly 1 during binding.

[0047] It should be noted 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, and each connecting part of the right fixing plate 12 is provided with a connecting hole; the fixed end of the upper hook and loop fastener 131 is installed at the connecting part of the upper end of the left fixing plate 11, and the free end of the upper hook and loop fastener 131 passes through the connecting hole of the upper end of the right fixing plate 12 and is then folded back, and the free end of the upper hook and loop fastener 131 is fastened to the part of the upper hook and loop fastener 131 located between the left fixing plate 11 and the right fixing plate 12 through the hook and loop fastener structure; similarly, the fixed end of the lower hook and loop fastener 132 is installed at the connecting part of the lower end of the left fixing plate 11, and the free end of the lower hook and loop fastener 132 passes through the connecting hole of the lower end of the right fixing plate 12 and is then folded back, and the free end of the lower hook and loop fastener 132 is fastened to the part of the lower hook and loop fastener 132 located between the left fixing plate 11 and the right fixing plate 12 through the hook and loop fastener structure.

[0048] Example 7, as Figure 5 As shown, the difference between this embodiment seven and embodiment one is that: the front support block 21 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.

[0049] Among them, the support block strap 23 is a Velcro strap, which passes through the through hole 2121 of the protrusion 212; in use, the two ends of the support block strap 23 are fastened together by the Velcro structure.

[0050] When the support block strap 23 is fastened to the lower end of the patient's calf or ankle, the support block strap 23 is connected to the front support block 21 through the protrusion 212, thereby enabling the front support block 21 to be connected and installed at the lower end of the patient's calf or ankle.

[0051] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
