Description
Technical Field
The utility model relates to the technical field of surgical medical instruments, in particular to a skin stretching device capable of realizing negative pressure suction.
Background
Aiming at the large-area defects of skin soft tissues caused by diabetes, trauma, tumor and other reasons, the common treatment modes at present are of two types: skin flap implantation and skin stretching.
The skin stretching technology is to stretch the skin by external force of a skin stretching device, and promote skin regeneration by utilizing the self skin viscoelasticity and regeneration capacity so as to achieve the aim of reducing and closing skin defects. The skin stretching devices commonly used in the market at present have two main types of invasive skin stretching devices and non-invasive skin stretching devices: invasive skin stretching devices are skin stretching devices that damage normal skin around the wound margin, and can be classified into Kirschner wire skin stretching devices, pull rod skin stretching devices, rubber, silicone tube skin stretching devices, and the like. Non-invasive skin retractors are adhesive skin retractors that do not or minimally damage the skin surrounding the wound surface, and are mainly available in both ZipLine and TopClosure. On one hand, the service time of the skin stretching device can reach several months, which has a certain influence on the daily life of a patient, and on the other hand, the skin stretching device needs to cross the skin defect area in use, so that the dressing change of the wound surface can be influenced, the wound surface can not be treated by utilizing the negative pressure closed drainage technology, and the wound surface infection chance is increased.
The skin flap transplanting technology is to transplant the skin with blood supply to the site needing to be repaired so as to achieve the purpose of closing the skin defect. Before performing skin flap transplantation, the wound surface is treated by adopting a negative pressure sealing drainage technology, and pus and soft tissue exudates at the wound surface are led out by negative pressure suction after the wound surface is sealed, so that tissue edema is reduced, germ growth is inhibited, infection probability is reduced, and granulation tissue growth of the wound surface is promoted, so that the wound surface meets the requirements of skin flap transplantation. On the one hand, the cost of skin flap transplantation is relatively high, and a large economic burden is imposed on some patients, on the other hand, skin flap transplantation is usually carried out by taking autologous skin of the patient, and the regeneration capability of the autologous skin is not utilized, so that the skin flap transplantation is not suitable when the area of the skin defect is too large.
In conclusion, the skin stretching technology and the negative pressure closed drainage technology are combined, so that the regeneration capacity of autologous skin is utilized, the probability of wound infection is reduced, and the method is a research direction of the current treatment of large-area defects of skin soft tissues.
