Description
Technical Field
The present invention relates to medical devices, and more particularly to a device for cleaning wound tissue and an assembly formed by assembling parts to accommodate different wound applications.
Background
Trauma is the destruction and damage of human tissues or organs by mechanical factors such as: trauma, burn, bedsore, diabetic foot, and postoperative incision. Wounds not only occur at high rates but also vary widely in degree, and the condition of injury can be severe and complex, even endangering the lives of the injured people.
Not only can the dead or devitalized tissue impede the wound healing process, but the dead tissue or foreign body provides an environment for bacterial growth, increasing the risk of infection and sepsis. On the one hand, the wound should be cleaned in order for the medical staff to correctly assess the wound formed on the tissue and also to be able to see clearly the tissue structure of the wound bed. Debridement, on the other hand, allows the wound to "heal" to an acute state, thereby restarting and accelerating the normal healing process of the wound.
Debridement is a surgical procedure, often performed by specially trained, experienced specialists, using surgical instruments such as: a blade, a curette, scissors, tweezers and the like to remove foreign matters in an open wound, cut necrotic, inactivated or severely polluted tissues, suture the wound, reduce the pollution as much as possible and even change the tissue into a clean wound, achieve the purpose of primary healing, and are beneficial to the recovery of the function and the shape of the injured part.
