Description
Technical Field
[0001] This utility model relates to the field of soft tissue transition cap technology, specifically a soft tissue transition cap with a limiting structure. Background Technology
[0002] In recent years, with the aging population and frequent sports injuries, the number of knee-related surgeries has been increasing year by year. Common surgeries include knee replacement, cruciate ligament reconstruction, meniscus repair, and cartilage repair. Post-operatively, the soft tissue area below the knee is often fragile due to incisions, sutures, and local reconstruction, requiring special protection during recovery. Currently, soft tissue transition caps are being used in medical assistance to protect the soft tissue below the knee after surgery. These caps provide external support, helping the soft tissue to recover gradually under appropriate tension and promoting better healing.
[0003] However, most soft tissue transition caps currently available on the market are one-piece structures that are fixed below the knee after being worn. While they provide some protection, they can cause the entire transition cap to twist significantly with the joint movement when the patient walks or moves their knee. This makes it difficult to effectively control the local range of motion in the soft tissue area and can easily lead to excessive rotation of the sutured area after surgery. Therefore, there is an urgent need for a soft tissue transition cap with a limiting structure to solve the above-mentioned technical defects. Utility Model Content
[0004] The purpose of this invention is to provide a soft tissue transition cap with a limiting structure to solve the problem mentioned in the background art, which is that the integrated structure has no rotation limiting and is prone to excessive rotation of the soft tissue in the postoperative suture area.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a soft tissue transition cap with a limiting structure, comprising a lower cap body, a middle cap body, and an upper cap body. The lower cap body is disposed below the upper cap body, and the middle cap body is installed between the upper cap body and the lower cap body. The upper cap body and the lower cap body are connected and fixed through the middle cap body. Limiting blocks are provided at the front and rear ends of the middle cap body, and limiting cylinders are provided at the front and rear ends of the upper cap body. A positioning groove is provided in the middle of the interior of the upper cap body, and a boss is provided in the middle of the interior of the middle cap body. After the upper cap body and the middle cap body are engaged, the boss is embedded in the positioning groove, and the limiting cylinder and the limiting block are fitted and matched.
[0006] As a further technical solution of this utility model, an upper rotating piece is movably connected to the right side of the upper cap body, and a lower rotating piece is movably connected to the right side of the middle cap body. A rotating pin is installed between the upper rotating piece and the lower rotating piece, and the upper rotating piece and the lower rotating piece rotate relative to each other around the rotating pin.
[0007] As a further technical solution of this utility model, screw holes are provided on both sides of the lower cap body edge, and connecting bolts are installed on both sides of the middle cap body edge, and the middle cap body and the lower cap body are fixedly connected by connecting bolts.
[0008] As a further technical solution of this utility model, the curvature of the bottom end of the upper hat body matches that of the middle hat body, and the shape of the middle hat body matches that of the lower hat body.
[0009] As a further technical solution of this utility model, both the upper and lower cap bodies are equipped with straps, which are used to bind the upper and lower cap bodies to the soft tissues of the knee.
[0010] As a further technical solution of this utility model, the upper cap body, the middle cap body and the lower cap body are all processed with through grooves on the left side. The upper cap body, the middle cap body and the lower cap body are all made of elastic nylon material and can be opened and closed through the through grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the soft tissue transition cap with the limiting structure not only restricts the range of rotation and prevents excessive rotation, but also retains a certain degree of flexibility, thereby reducing postoperative swelling and the risk of obstructed blood circulation, and also allows for adjustment of the covering strength and rotation amplitude at different recovery stages;
[0012] (1) By setting up an upper cap body, a middle cap body and a lower cap body, an upper rotating plate, a limiting cylinder, a positioning groove, a connecting bolt, a boss, a lower rotating plate, a limiting block and a rotating pin, the middle cap body plays a connecting role between the upper and lower parts, which can limit the range of rotation, prevent excessive twisting from causing secondary damage, effectively protect the soft tissue around the knee after surgery, prevent the suture area from tearing due to excessive rotation, and at the same time retain a certain degree of flexibility to adapt to the natural micro-movement of the knee joint, ensure that the soft tissue recovers under natural tension, and improve the speed and quality of postoperative repair.
[0013] (2) By setting up connecting bolts and straps, the transition cap is divided into three parts: upper cap body, middle cap body and lower cap body. According to the shape of the bony support area below the knee, it is accurately wrapped and installed below the knee, thereby protecting the soft tissue around the surgical area as a whole. The middle cap body and the lower cap body are fixedly connected by connecting bolts to form a stable support. Straps are set on the outside of the upper cap body and the lower cap body to firmly tie the whole body to the leg. It fully considers the problem that the soft tissue needs stable support during the recovery period after surgery but avoids excessive local pressure. It can reduce postoperative swelling and reduce the risk of obstructed blood circulation.
[0014] (3) By setting up an upper cap body, a middle cap body, a lower cap body, and a through groove, the transition cap is made of elastic nylon material. In actual use, the through groove can be used to manually expand and close, which can flexibly adapt to different patients' knee sizes and postoperative soft tissue changes. Through the segmented structure design, the covering strength and rotation range can be adjusted at different recovery stages to ensure the dynamic growth of soft tissues around the knee joint, thus solving the problem of damage caused by the high hardness and poor adaptability of traditional fixation devices.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4An embodiment of this utility model provides: a soft tissue transition cap with a limiting structure, including a lower cap body 11, a middle cap body 6 and an upper cap body 1. The lower cap body 11 is provided below the upper cap body 1, and the middle cap body 6 is installed between the upper cap body 1 and the lower cap body 11. The upper cap body 1 and the lower cap body 11 are connected and fixed by the middle cap body 6. The front and rear ends of the middle cap body 6 are provided with limiting blocks 10, and the front and rear ends of the upper cap body 1 are provided with limiting cylinders 4. The upper cap body 1 has a positioning groove 5 in the middle, and the middle cap body 6 has a boss 8 in the middle. After the upper cap body 1 and the middle cap body 6 are engaged, the boss 8 is embedded in the positioning groove 5. The limiting cylinder 4 is fitted and matched with the limiting block 10. The upper cap body 1 is movably connected to the right side of the upper cap body 2, and the middle cap body 6 is movably connected to the right side of the lower rotating piece 9. A rotating pin 14 is installed between the upper rotating piece 2 and the lower rotating piece 9. The upper rotating piece 2 and the lower rotating piece 9 rotate relative to each other around the rotating pin 14.
[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transition cap consists of three parts: an upper cap body 1, a middle cap body 6, and a lower cap body 11. The middle cap body 6 serves as a connecting element between the upper and lower parts. The middle cap body 6 is fixed to the lower cap body 11 by connecting bolts 7. A lower rotating plate 9 is connected to the right side of the middle cap body 6, and an upper rotating plate 2 is connected to the right side of the upper cap body 1. The two are movably connected by a rotating pin 14, which facilitates the relative rotation of the upper cap body 1 and the middle cap body 6. When the upper cap body 1 is installed on the middle cap body 6, the positioning groove 5 is embedded in the outside of the boss 8. When the upper cap body 1 and the middle cap body 6 rotate, the boss 8 slides inside the positioning groove 5. The limiting cylinder 4 cooperates with the limiting block 10 to limit the range of rotation.
[0023] Screw holes 12 are provided on both sides of the lower cap body 11, and connecting bolts 7 are installed on both sides of the middle cap body 6. The middle cap body 6 and the lower cap body 11 are fixedly connected by the connecting bolts 7. The bottom curvature of the upper cap body 1 matches the middle cap body 6, and the shape of the middle cap body 6 matches the lower cap body 11. Both the upper cap body 1 and the lower cap body 11 are equipped with straps 3. The upper cap body 1 and the lower cap body 11 are tied to the soft tissue of the knee by the straps 3.
[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during actual installation, external force is applied through the through groove 13 to open the upper cap 1, the middle cap 6 and the lower cap 11 respectively. According to the shape of the bony support area below the knee, they are accurately wrapped and installed below the knee, thereby protecting the soft tissue around the surgical area as a whole. The middle cap 6 and the lower cap 11 are fixedly connected by connecting bolts 7 to form a stable support. The upper cap 1 and the lower cap 11 are provided with straps 3 on the outside. The straps 3 are common elastic bands with fixing buckles, which are used to firmly bind the whole to the leg.
[0025] The upper cap 1, the middle cap 6 and the lower cap 11 are all machined with through grooves 13 on the left side. The upper cap 1, the middle cap 6 and the lower cap 11 are all made of elastic nylon and are opened and closed through the through grooves 13.
[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transition cap is made of elastic nylon material. In actual use, it can be flexibly adapted to different patients' knee sizes and postoperative soft tissue changes through the through groove 13 in conjunction with manual expansion and closure.
[0027] Working principle: During actual installation, external force is applied through the through groove 13 to open the upper cap 1, middle cap 6, and lower cap 11 respectively. Based on the shape of the bony support area below the knee, they are accurately installed below the knee. The middle cap 6 serves as a connecting element, fixed to the lower cap 11 by connecting bolts 7. A lower rotating plate 9 is connected to the right side of the middle cap 6, and an upper rotating plate 2 is connected to the right side of the upper cap 1. The two are movably connected by a rotating pin 14, facilitating relative rotation between the upper cap 1 and the middle cap 6. After the upper cap 1 is installed onto the middle cap 6, the positioning groove 5 is embedded in the outside of the boss 8. When the upper cap 1 and the middle cap 6 rotate, the boss 8 slides inside the positioning groove 5. The limiting cylinder 4 and the limiting block 10 cooperate to limit the range of rotation. The middle cap 6 and the lower cap 11 are fixedly connected by the connecting bolt 7 to form a stable support. The upper cap 1 and the lower cap 11 are provided with straps 3 on the outside to securely bind the whole to the leg. This fully considers the problem that the soft tissue needs stable support during the recovery period after surgery, but avoids excessive local pressure. It can reduce postoperative swelling and reduce the risk of obstructed blood circulation. The transition cap is made of elastic nylon material, which can flexibly adapt to different patients' knee sizes and postoperative soft tissue changes.
