Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an incision sealing negative pressure drainage device.
Background
Vacuum Sealing Drainage (VSD) was first proposed in 1992 by doctor Fleischmann in Germany, and it was covered with medical sponge foam and sealed with a medical film, and the exterior of the wound was connected to a Drainage tube which was connected to a negative pressure source so as to maintain a constant negative pressure and to draw the exudate from the wound. Two researchers in north america in 1997, Morykwas and argentia, first described the mechanism of action of VSDs in the form of a paper, consisting mainly of several aspects: 1. increasing blood perfusion at the incision application and improving local blood supply; 2. the generation of granulation tissues is accelerated; 3. the number of bacteria at the wound is reduced, and the infection probability is reduced; 4. increasing the survival rate of random skin flaps. After professor fur and moral in 1994 is introduced into China, VSD technology is developed in nearly 30 years and is widely applied to general surgery, burn department and traumatic orthopedics department. Briefly, VSD is currently used primarily in the "wound" of complex soft tissue defects and open fractures, rather than "surgical incisions," to provide time for later stage flap transplantation or the next procedure.
With the development of society, traffic accidents are more and more, so that fracture patients and patients who need internal fixation operation of incision reduction are increased. However, due to the selection of the operation time and the characteristics of the fracture part itself, more and more patients are confronted with necrosis, nonunion or infection of the skin soft tissue of the operation incision part after the fracture operation, especially the lower limb fracture and the foot fracture (such as calcaneus). Meanwhile, the development of orthopedic theory from AO to BO (AO means strong internal fixation emphasizes continuity of fracture anatomy and mechanical integrity in early recovery, BO means biological fixation emphasizes fracture treatment concept mainly based on biology for mainly maintaining local soft tissue blood circulation), and also makes people pay more attention to the problem of protecting soft tissue blood circulation. In view of the above problems, foreign researchers have tried to apply VSD technology to surgical incisions after fracture surgery, which indicates that the incidence of postoperative incision complications in patients is significantly reduced.
However, the conventional VSD device is applied to a closed incision of a fracture surgery, and also faces some problems because VSDs on the market are mostly used for open wounds which are difficult to close temporarily, foam dressings can only be externally arranged on superficial wounds, and although various drainage tubes are provided, the VSDs are only limited to be internally or externally arranged relative to the foam dressings, because the fracture surgery part is often deeper, the oozing blood in the deep soft tissue layer after suturing needs to be provided with longer drainage tubes, and the superficial foam dressings can cause insufficient effusion drainage for such closed incisions, so that the dressings are dried and hardened prematurely or the drainage tubes are blocked, and the surgery incision still faces risks of postoperative infection and other complications.
