Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a protective brace used for repairing hand soft tissue defect with a pedicled skin flap after surgery. Background Art

[0002] Hand trauma is prone to skin and soft tissue defects. As the hand is the second face of a person, we need to restore the hand function and maintain the appearance of the hand to the maximum extent during the surgical repair process. At present, flap transplantation is often used in clinical practice to repair skin and soft tissue defects on hand wounds. Flap transplantation can be divided into pedicled flap transplantation and free flap transplantation. Both can cover the wound and restore function. However, the use of local pedicled flap surgery will inevitably sacrifice the appearance of the forearm during the flap cutting process, leaving scar hyperplasia, destroying the beauty, and also paying the price of sacrificing a major blood vessel; free flap treatment, although the donor area is concealed and achieves a beautiful effect, but the operation is difficult and time-consuming, and it is not easy to promote and use on a large scale. Moreover, it is inevitable that all patients use free flaps to repair the wound, which is a bit of an exaggeration.

[0003] Therefore, some scholars advocated the use of abdominal flaps to repair hand skin defects in 2009. This surgical method has the advantages of simple operation, high flap survival rate, large defect area coverage, and better hand function recovery after surgery. However, patients need to maintain a forced posture for a long time after surgery, and undergo a second surgery to cut the pedicle after the flap survives. The waiting period for the second surgery greatly affects the patient's quality of life, causing most patients to choose long-term bed rest, which has adverse effects on patients both physically and psychologically. Therefore, after the abdominal pedicled flap repair surgery, the fixation of the affected limb directly affects the surgical effect.

[0004] However, there is no consensus in clinical practice on postoperative wound protection and fixation methods for abdominal pedicled flaps. The traditional abdominal belt fixation and plaster fixation methods are unstable and there are risks of compression, traction, and rotation of the flap pedicle. Although the external fixator can fix the affected limb firmly, it is expensive and fixes the forearm bone to the ilium, restricting the patient's activity. There is also the risk of iatrogenic injuries such as nail tract infection, osteomyelitis, and fractures. Long-term forced fixation can easily cause discomfort such as joint pain in patients.
