Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a postoperative brace assistive device for posterior cruciate ligament surgery. Background Technology

[0002] The posterior cruciate ligament (PCL) attaches posteriorly between the medial and lateral tibial condyles, extending to the posterior aspect of the proximal tibia, approximately 0.5 cm below the tibial plateau. The PCL extends superiorly and anteromedially, posteromedially to the anterior cruciate ligament (ACL), and inserts posteriorly to the lateral aspect of the medial femoral condyle. The PCL is larger and shorter than the ACL, and its strength is twice that of the ACL; therefore, it is a major stabilizing factor in the knee joint.

[0003] When the knee is extended, the posterior cruciate ligament appears to run vertically, acting as the axis of knee joint rotation. It bears 89% of the resistance to posterior displacement of the tibia relative to the femur. Therefore, it is essential to use a brace to provide support to the posterior aspect of the tibia, counteracting the effects of gravity and preventing the reconstructed posterior cruciate ligament from being affected by gravity after surgery, thus accelerating the patient's recovery after ligament reconstruction.

[0004] In the prior art, please refer to Figure 3 The image shown is a physical representation of a posterior cruciate ligament (PCL) brace currently in use. The downsides of using an integrated PCL brace are that the pre-operative leg circumference measurement and post-operative swelling reduce patient comfort, making it feel very tight. Furthermore, the brace's constriction further hinders blood circulation and exacerbates swelling, resulting in poor usability and a relatively unpleasant experience. Utility Model Content

[0005] Therefore, it is necessary to provide a postoperative brace for posterior cruciate ligament that is relatively easy to use and provides relatively good protection.

[0006] In a first aspect, this application provides a postoperative brace assist device for posterior cruciate ligament surgery, comprising:

[0007] A thermoplastic sheet having a leg-circle matching arc surface, and a plurality of first ventilation holes distributed on the thermoplastic sheet;

[0026] In one aspect, this application provides a posterior cruciate ligament postoperative brace assistive device 10, please refer to [link to relevant documentation]. Figure 1The posterior cruciate ligament (PCL) postoperative brace support device 10 includes: a thermoplastic plate 100, a BK plate 200, a breathable plate 300, and a protective sleeve 400. The thermoplastic plate 100 has a leg-circumference matching arc surface 110. The thermoplastic plate is a low-temperature thermoplastic plate with a leg-circumference matching arc surface, which can be molded according to the user's leg circumference to provide certain support to the posterior tibia at the height of the brace support. Multiple first breathable holes 111 are evenly distributed on the thermoplastic plate 100. The BK plate 200 is attached to the leg-circumference matching arc surface 110 of the thermoplastic plate 100. The BK plate 200 has a wedge-shaped structure, and its thickness gradually increases from top to bottom (x direction in the figure), from 2.5 cm to 3.0 cm. The BK plate is a flexible EVA (ethylene-vinyl acetate copolymer) sheet. Because the BK board has poor breathability, a breathable panel 300 is also provided on the BK board. The breathable panel 300 is attached to the entire BK board 200 and the thermoplastic board 100. The protective cover 400 is fitted over the thermoplastic board 100, the BK board 200, and the breathable panel 300 that form a whole; that is, the protective cover 400 covers the thermoplastic board 100, the BK board 200, and the breathable panel 300 that form a whole. The protective cover is used for wearing. The protective cover 400 is provided with a first strap 410 and a second strap 420. The first strap 410 is provided with a first Velcro fastener, and the second strap 420 is provided with a second Velcro fastener. The first strap 410 and the second strap 420 are tied together by the cooperation of the first Velcro fastener and the second Velcro fastener, and the tightness can be adjusted according to the leg circumference. For example, the first strap 410 and the second strap 420 are both located on opposite sides of the middle of the protective sleeve.

[0027] The aforementioned posterior cruciate ligament (PCL) postoperative brace support device uses a low-temperature thermoplastic plate with a leg-circumference matching arc surface, allowing it to mold to the user's leg circumference. To ensure the brace support height provides adequate support to the posterior tibia, a layer of BK plate is adhered to the low-temperature thermoplastic plate, thus ensuring support and protection. Since the BK plate has poor breathability, a breathable plate is adhered on top. Finally, a protective cover is placed over the entire brace support. The inner surface of the protective cover is quick-drying fabric, and the outer surface is fleece. Two straps with Velcro are attached to each side, allowing for adjustment of tightness according to leg circumference. The advantages of this structure are: the brace support is compact, easy to fix and remove; during functional exercises and rest, only the brace support needs to be worn, and the knee brace can be removed; any knee brace available online can be used, saving costs. The PCL postoperative brace support device of this application offers relatively good ease of use, good protective effect, and relatively low overall cost.

[0028] In one embodiment, the protective case 500 has an inner layer facing the user and an outer layer facing the user, the inner and outer layers being made of different materials. For example, the inner layer is a quick-drying fabric layer, and the outer layer is a fleece layer. The quick-drying fabric layer improves the user's wearing experience when the user sweats.

[0029] In one embodiment, the BK board 200 has a first adhesive layer on the side near the thermoplastic board 100, and the BK board 200 is bonded to the thermoplastic board 100 through the first adhesive layer. This allows for better fixation of the BK board to the thermoplastic board.

[0030] In one embodiment, the breathable panel 300 has a second adhesive layer on the side adjacent to the BK panel 200, and the breathable panel 300 is bonded to the BK panel 200 and the thermoplastic panel 100 as a whole through the second adhesive layer. This effectively secures the breathable panel 300 to the BK panel 200.

[0031] In one embodiment, the thermoplastic plate has rounded corner structures at its four corners. This rounded corner structure allows the thermoplastic plate to better fit the user's legs, further improving the wearing experience.

[0032] In one embodiment, the breathable plate 300 has a plurality of second breathable holes 310 evenly distributed on it. For example, the thermoplastic plate 100 has a plurality of first breathable holes 111 evenly distributed on it. For example, both the first breathable holes 111 and the second breathable holes 310 are circular, and for example, the size of the second breathable holes 310 is larger than that of the first breathable holes 111. This further improves the breathability. For example, the breathable plate has a hollow structure with openings at both ends, and the overall structure after the thermoplastic plate and the BK plate are connected is bonded within the hollow structure.

[0033] The aforementioned posterior cruciate ligament (PCL) postoperative brace support device uses a low-temperature thermoplastic plate with a leg-circumference matching arc surface, allowing it to mold to the user's leg circumference. To ensure the brace support height provides adequate support to the posterior tibia, a BK plate is adhered to the low-temperature thermoplastic plate, thus ensuring support and protection. Since the BK plate has poor breathability, a breathable plate is adhered on top. Finally, a protective cover is placed over the entire brace support. The inner surface of the protective cover is quick-drying fabric, and the outer surface is fleece. Two straps with Velcro closures are attached to each side, allowing for adjustment of tightness according to leg circumference. The advantages of this structure are: the brace support is compact, easy to fix and remove; during functional exercises and rest, only the brace support needs to be worn, and the knee brace can be removed. It can also be fitted with any knee brace available online, saving costs. The PCL postoperative brace support device of this application offers relatively good ease of use, good protective effect, and relatively low overall cost.

[0034] For further explanation of the above-mentioned posterior cruciate ligament postoperative brace support device, please refer to [link to relevant documentation]. Figure 2 This describes the assembly process of a postoperative brace for posterior cruciate ligament surgery. In section A, a low-temperature thermoplastic plate 2 is used as the base based on the leg circumference. To ensure the brace support provides sufficient support to the posterior tibia, a layer of BK plate 1 is adhered to the low-temperature thermoplastic plate 1. The structure after the low-temperature thermoplastic plate 1 is bonded with the BK plate 2 is as follows. Figure 2 As shown in B in the diagram. Because the BK board has poor air permeability, a layer of perforated board 3 is then glued on top. The image after gluing the perforated board is shown in the diagram. Figure 2 As shown at point C in the diagram. Finally, a protective sleeve 4 is placed over the entire brace support. The inner surface of the protective sleeve 4 is made of quick-drying fabric, and the outer surface is made of fleece. There is a strap 5 on each side with Velcro 6, which can be adjusted according to the leg circumference. The final result after the perforated plate 3 is installed into the protective sleeve 4 is shown in the figure, thus obtaining the posterior cruciate ligament postoperative brace auxiliary device of this application.

[0035] The advantages of the above structure are: the brace support is compact, easy to fix and remove; during functional exercises and rest, only the brace support needs to be worn, and the knee brace can be removed; at the same time, any knee brace available online can be used, saving costs. In this application, the low-temperature thermoplastic plate and BK plate can be adjusted on-site according to the patient's leg circumference. The perforated plate can be selected in color (pink and blue) according to the patient's preference, and the perforated plate combined with the quick-drying fabric of the protective cover provides breathability. In addition, the protective cover of this application can be removed for washing.

[0036] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. It should be noted that the terms "in one embodiment," "for example," and "again," etc., in this application are intended to illustrate the application and not to limit it. The embodiments described above only illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
