Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a minimally invasive fascial tension reduction device for compartment syndrome. Background Technology

[0002] Compartment syndrome is an acute and critical condition in trauma surgery, especially in trauma orthopedics. If not detected and treated promptly, it can lead to lifelong disability, amputation, or even death. A compartment is a space formed by strong, resilient tissue structures such as bone, interosseous membranes, muscle septa, and deep fascia, housing muscles, nerves, and blood vessels. After a violent injury, soft tissue swelling is significant, requiring ample space to accommodate the swollen tissue. However, due to the lack of extensibility within the compartment, it cannot effectively increase the space, leading to increased pressure. When this pressure exceeds the pressure within the blood vessels supplying the muscles and nerves, it causes ineffective blood supply to these tissues, resulting in ischemia. Prolonged ischemia further leads to ischemic necrosis of muscle and nerve tissues, causing functional impairment and limb disability in mild cases, and amputation in severe cases. Excessive absorption of toxins from necrotic tissue can even be life-threatening.

[0003] Current treatment methods tend to involve emergency fasciotomy for tension reduction: 1. Open fasciotomy, which involves a large skin incision, causing significant trauma and bleeding / exudation; 2. Minimally invasive fasciotomy, which, due to the lack of specialized tools, can easily damage soft tissues such as blood vessels, nerves, and muscles outside the deep fascia during the procedure. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a minimally invasive fascial tension-reducing device for compartment syndrome, which solves the problem that existing minimally invasive open incision tension reduction methods lack specialized tools and are prone to damaging soft tissues outside the deep fascia during surgery.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A minimally invasive fascial tension-reducing device for compartment syndrome is provided, comprising a cutting block, a rod, and a handle connected in sequence. The length of the cutting block extends in the same direction as the length of the rod. A cutting groove with an outward opening is provided in the middle of the cutting block, and a herringbone-shaped cutting blade is provided at the bottom of the cutting groove.

[0007] This invention involves placing a cutting block on the surface of the deep fascia, with a handle connected to the cutting block via a rod. The operator can then use the handle to push the cutting block forward, thereby longitudinally cutting the deep fascia to the desired length during the pushing process. This achieves deep fascia cutting and tension reduction, releases pressure within the osteofascial chamber, restores tissue blood supply, and reduces the risk of ischemic necrosis of nerves, muscles, and other tissues.

[0008] Furthermore, the cutting edge has a rounded corner structure.

[0009] Furthermore, the cross-section of the cutting block along its length is elliptical, and the extension direction of the major axis of the ellipse is the same as the extension direction of the rod length.

[0010] Furthermore, the rod includes an extension rod and a diagonal bar connected to the extension rod, the diagonal bar being connected to the handle.

[0011] Furthermore, the angle between the extension rod and the diagonal rod is less than 150°.

[0012] Furthermore, the handle is equipped with anti-slip texture.

[0013] Furthermore, a rubber sleeve is fitted onto the handle.

[0014] This utility model discloses a minimally invasive fascial tension-reducing device for compartment syndrome, the beneficial effects of which are:

[0015] This invention utilizes a minimally invasive incision to position the cutting block at the superficial and deep surfaces of the deep fascia. During the advancement process, the deep fascia can be longitudinally cut to the desired length, achieving deep fascia incision and tension reduction. This releases pressure within the osteofascial compartment, restores tissue blood supply, and reduces the risk of ischemic necrosis of nerves, muscles, and other tissues. Simultaneously, while achieving tension reduction, it minimizes trauma, effectively protects soft tissues, reduces the difficulty of subsequent treatment, minimizes scarring, and lowers treatment costs.

[0019] The present invention is described in detail with respect to specific embodiments in order to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, any changes that are within the spirit and scope of the present invention as defined and determined by the appended claims are obvious. All utility model creations utilizing the concept of the present invention are protected.

[0020] refer to Figures 1-2 This is a schematic diagram of a fascial minimally invasive tension-reducing device for compartment syndrome in this embodiment. Its purpose is to solve the problem that existing minimally invasive incision tension reduction methods lack specialized tools and are prone to damaging soft tissues outside the deep fascia during surgery. The specific structure of this embodiment will be described in detail below.

[0021] A minimally invasive fascial tension-reducing device for compartment syndrome includes a cutting block 1, a rod 2, and a handle 3 connected in sequence.

[0022] The cutting block 1 extends in the same direction as the rod 2, which facilitates its entry into the patient's minimally invasive opening and reduces the opening area. This allows the cutting block 1 to penetrate the superficial and deep surfaces of the patient's deep fascia. The cutting block 1 has an outward-facing cutting groove 4 in the middle, and a herringbone-shaped cutting blade 5 at the bottom. The cutting blade 5 has a rounded end. The herringbone-shaped cutting blade 5 at the bottom of the cutting groove 4 allows the operator to simply push the cutting block 1 with the handle 3 to cut and reduce tension in the deep fascia, release intramuscular pressure, restore tissue blood supply, and reduce the risk of ischemic necrosis of nerves, muscles, and other tissues.

[0023] Specifically, the cutting block 1 is an ellipsoid, such as a rugby ball. The cross-section of the cutting block 1 along its length is elliptical, and the cross-section along its width is circular. The extension direction of the major axis of the ellipse is the same as the extension direction of the length of the rod 2. This makes the ellipsoidal cutting block 1 easier to enter the patient's minimally invasive opening, reduces the area of ​​the patient's minimally invasive opening, and at the same time reduces damage to other soft tissues during entry, effectively protecting soft tissues, reducing the difficulty of later treatment, reducing scarring, and lowering treatment costs.

[0024] Specifically, the rod 2 includes an extension rod 21 and an inclined rod 22 connected to the extension rod 21. One end of the extension rod 21 is connected to the cutting block 1, and the other end of the extension rod 21 is connected to one end of the inclined rod 22. An angle is formed between the extension rod 21 and the inclined rod 22, and the angle is less than 150°. The other end of the inclined rod 22 is connected to the handle 3, so that the cutting block 1 can be pushed by the handle 3 to cut and reduce tension in the deep fascia. The angle between the extension rod 21 and the inclined rod 22 is also operated by the operator to prevent the operator's hand from being interfered with by the patient's limb and to prevent the pushing direction of the cutting block 1 from deviating.

[0025] Specifically, the handle 3 is provided with anti-slip texture 31, which can be knurled or a rubber sleeve is provided on the handle 3. The purpose is to prevent the operator from making mistakes such as slipping, which could cause the cutting block 1 to deviate in the direction of the operation.

[0026] The working principle of the fascial minimally invasive tension-reducing device for compartment syndrome in this solution is as follows:

[0027] In practical applications, this utility model is referenced. Figures 1-2 In use, the operator inserts the cutting block 1 through the minimally invasive opening of the patient's surgery, reaching the osteofascial compartment. The cutting block 1 is positioned on the superficial and deep surfaces of the deep fascia. Then, the operator pushes the cutting block 1 forward using the handle 3, and the herringbone-shaped cutting blade 5 at the bottom of the cutting groove 4 cuts and reduces tension in the deep fascia, releasing pressure within the osteofascial compartment, restoring tissue blood supply, and reducing the risk of ischemic necrosis of nerves, muscles, and other tissues. At the same time, it reduces damage to other soft tissues during entry, effectively protecting soft tissues, reducing the difficulty of subsequent treatment, minimizing scarring, and lowering treatment costs.

[0028] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
