Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an external fixation strap for surgical incision dressings on the torso. Background Technology

[0002] The number of open surgeries on the trunk, such as spinal decompression and internal fixation, kidney transplantation, liver transplantation, gastrointestinal tumor resection, cardiac surgery, and aortic dissection, is increasing year by year. These surgeries often involve large surgical incisions, making the promotion of rapid, primary healing of these incisions a pressing need for healthcare professionals. Although various wound dressings are currently used to treat surgical incisions, patient turning often causes the dressings to crack or fall off, leading to incision infection. If not treated promptly, bacteria can enter deeper tissues through the surgical incision, causing sepsis.

[0003] For the first three days after surgical incision suturing, dressings need to be changed daily due to usually abundant discharge. For deep wounds caused by trauma, the risk of infection is higher, so dressing changes need to be increased to 1-2 times daily. After three days of wound healing, or when discharge gradually decreases and there is no accompanying infection, the frequency of dressing changes can be reduced to once every three days. To prevent dressing dislodgement, common external fixation devices such as chest straps, lumbar supports, and pelvic braces are often used clinically to wrap the dressing, preventing it from falling off when the patient turns over.

[0004] In existing technologies, a wound covering module is used to secure dressings on a fixation strap. However, since the wound covering module is fixed to the fixation strap, when the surgical incision is on the patient's front, the ends of the fixation strap can only be connected and removed by wrapping around to the patient's back. Changing the dressing requires the patient to get up or turn over, causing discomfort and hindering wound healing. For example, patent CN220158556U has a fixation frame that is fixedly connected to the surface of the fixation strap, and patent CN221205910U has a left abdominal binder piece fixedly connected to a left-side connecting strap, and a right abdominal binder piece fixedly connected to a right-side connecting strap; both suffer from the aforementioned problems. Utility Model Content

[0005] In view of this, the present invention provides an external fixation strap for surgical incision dressings of the torso, wherein the wound covering module can be adjusted according to the position of the surgical incision.

[0030] It should also be noted that all connections involved in this utility model can be achieved using conventional connection methods and do not involve any innovation.

[0031] This utility model relates to an external fixation bandage for surgical incisions in the trunk. With the increasing aging of the population, the number of open surgeries on the trunk, such as spinal decompression and internal fixation, kidney transplantation, liver transplantation, gastrointestinal tumor resection, cardiac surgery, and aortic dissection surgery, is increasing year by year. These surgeries often involve large surgical incisions, making the promotion of rapid primary healing of these incisions a pressing need for medical professionals. Although various wound dressings are currently used to treat surgical incisions, patient turning often causes the dressings to crack and fall off, leading to incision infection. If not treated promptly, bacteria can enter deep tissues through the surgical incision, causing sepsis.

[0032] For the first three days after surgical incision suturing, dressings need to be changed daily due to usually abundant discharge. For deep wounds caused by trauma, the risk of infection is higher, so dressing changes need to be increased to 1-2 times daily. After three days of wound healing, or when discharge gradually decreases and there is no accompanying infection, the frequency of dressing changes can be reduced to once every three days. To prevent dressing dislodgement, common external fixation devices such as chest straps, lumbar supports, and pelvic braces are often used clinically to wrap the dressing, preventing it from falling off when the patient turns over.

[0033] In existing technologies, a wound covering module is used to secure dressings on a fixation strap. However, since the wound covering module is fixed to the fixation strap, when the surgical incision is on the patient's front, the ends of the fixation strap can only be connected and removed by wrapping around to the patient's back. Changing the dressing requires the patient to get up or turn over, causing discomfort and hindering wound healing. For example, patent CN220158556U has a fixation frame that is fixedly connected to the surface of the fixation strap, and patent CN221205910U has a left abdominal binder piece fixedly connected to a left-side connecting strap, and a right abdominal binder piece fixedly connected to a right-side connecting strap; both suffer from the aforementioned problems.

[0034] For the reasons mentioned above, this utility model provides an external fixation bandage for trunk surgical incision dressings to solve the aforementioned technical problems. The following is a detailed description... Figures 1 to 6 The present invention will be described in detail below.

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides an external fixation strap for a surgical incision on the torso, including a fixation strap body 1, two guide rails 2, and a pressure relief pad 3.

[0037] The two guide rails 2 are parallel to the length of the fixing belt body 1, and are respectively located on one side of the two long sides of the fixing belt body 1. The two ends of the guide rails 2 are fixedly connected to the two ends of the fixing belt body 1. The pressure-reducing pad 3 is located on the fixing belt body 1, and its two sides are slidably connected to the two guide rails 2, allowing the position of the pressure-reducing pad 3 in the length of the fixing belt body 1 to be adjusted.

[0038] Before fixing the dressing, adjust the position of the pressure relief pad 3 along the length of the fixation band body 1 according to the location of the surgical incision. After positioning the pressure relief pad 3 at the dressing position, both ends of the fixation band body 1 can be wrapped around the patient's body to a convenient location for operation. After adjustment, the two ends of the fixation band body 1 will not be under the patient's body, avoiding discomfort at the end connection and causing skin pressure sores.

[0039] The pressure-reducing pad 3 has annular parts 4 on both sides, and the guide rail 2 passes through the corresponding annular parts 4. The annular parts 4 are circular rings, and the inner diameter of the circular ring is slightly larger than the outer diameter of the guide rail 2. The length of the annular parts 4 is equal to the length of the pressure-reducing pad 3.

[0040] The two ends of the fixation strap body 1 are connected by Velcro. The second rough-surface Velcro and the second hook-and-loop Velcro are located at the two ends of the fixation strap, respectively. The second rough-surface Velcro and the second hook-and-loop Velcro cooperate with each other to wrap the fixation strap body 1 around the surgical site and fix it firmly.

[0041] To improve patient comfort, the fixation strap body 1 consists of an inner lining and an outer lining. The outer lining is made of waterproof, breathable, and abrasion-resistant fabric, preferably waterproof nylon / polyester, Gore-Tex, or Cordura, with a thickness of 2mm to 3mm. The inner lining is made of antibacterial, breathable, and soft material, preferably one of mulberry silk, bamboo fiber, Tencel, or bamboo charcoal fiber, with a thickness of 1mm to 2mm. The pressure-reducing pad 3 is made of loose, soft, and breathable material, preferably polyurethane foam, polyethylene foam, rubber foam, or silicone sponge, with a thickness of 5mm to 10mm. The guide rail 2 is preferably made of soft and comfortable fabric.

[0052] The arc-shaped groove 501 is used for initial positioning of the guide rail 2. After changing the dressing, first cover the pressure-reducing pad 3 on the dressing, then pick up the guide rail 2 and place it into the arc-shaped groove 501. Then, wrap the connecting strap 502 around the guide rail 2 and fasten the first female buckle with the first female buckle 503.

[0053] In this embodiment, to improve patient comfort, the first length adjustment structure 6 includes a first textured hook and loop fastener 601 and a first hook and loop fastener 602. The textured hook and loop fastener 601 is located on the side of the first strap 101 opposite to the pressure-relieving pad 3, and the hook and loop fastener 602 is located on the side of the first strap 101 opposite to the pressure-relieving pad 3 and close to one end of the second detachable connection structure 7. The hook and loop fastener 602 is bonded to the textured hook and loop fastener 601. The length of the first strap 101 is adjusted by adjusting the position of the hook and loop fastener 602 bonded to the textured hook and loop fastener 601. The second length adjustment structure 8 has the same structure and adjustment method as the first length adjustment structure 6.

[0054] Based on the aforementioned length adjustment structure, the second detachable connection structure 7 includes a first adjusting buckle 701, a second adjusting buckle 703, a second sub-buckle 702, and a second female buckle. The first strap 101 passes through the first adjusting buckle 701, the second strap 102 passes through the second adjusting buckle 703, the second female buckle is connected to the first adjusting buckle 701, and the second sub-buckle 702 is connected to the second adjusting buckle 703, engaging with the second female buckle. The first hook-and-loop fastener 602 passes through the first adjusting buckle 701 and then adheres to the first rough-surface hook-and-loop fastener 601.

[0055] Specifically, a fabric cover is connected to both the first adjusting buckle 701 and the second adjusting buckle 702, and the second female buckle 702 is respectively set on the corresponding fabric cover.

[0056] To improve patient comfort, the first adjustment buckle 701 includes two opposing vertical plates and two opposing horizontal connectors. The vertical plates are flexible plates, and the connectors are flexible components. The two vertical plates and the two connectors are connected end to end to form a square frame. The vertical plates can be made of flexible plastic material, and the connectors can be made of non-elastic fabric. The second adjustment buckle 703 has the same structure as the first adjustment buckle 701.
