Embodiment 2

[0034] refer to Figure 4 , in this example the frame is a moldable frame, specifically a cylindrical wire. like Figure 4 As shown in , with cylindrical wire, the frame film is an elongated film with a certain width.

[0035] In this example, the width of the strip-shaped film is preferably 3-5 cm.

[0036] We can continuously wind such long strip structures and store them in the form of "rolls". And when in use, it is cut into different length specifications according to specific needs, such as Figure 4 as shown. Fix them around the skin respectively to form a square frame and frame film structure.

[0037] This structure is particularly suitable for postoperative recovery of transregional skin grafting. like Figure 5 As shown, it can form multiple planes that conform to the wound. And in this example, we preferably include three airbags, respectively fixed on three planes A, B, C.

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a post-dermoplasty auxiliary instrument. The post-dermoplasty auxiliary instrument is mainly composed of a frameand a frame attaching film. The instrument can be used for grafting skin in skin pieces within the same plane, and can be also used for grafting skin in cross-region skin pieces in different planes. By the utilization of the post-dermoplasty auxiliary instrument, wound edge shrinking and contraction of the skin-grafting skin pieces can be effectively resisted, then the flatness of the skin-grafting skin pieces is guaranteed, the skin attractiveness after dermoplasty is improved, and the success rate of the dermoplasty is increased. Meanwhile, an air bag is utilized for exerting pressure locally, in this way, local recovery can be accelerated, and forming of blackspots is restrained.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to auxiliary devices after skin grafting. Background technique [0002] Skin grafting is mainly used to repair various wounds (such as burns, wounds caused by trauma, and secondary wounds after scar excision, etc.), and is widely used in clinical practice. [0003] After skin grafting, the edge of the wound contracted inward, and the grafted skin also contracted centripetally. These two inward forces often lead to a large contracture of the grafted skin, making the appearance of the grafted site unsightly, and even affecting the function of the grafted site. In severe cases, the operation fails and needs to be repaired again. [0004] At the same time, different degrees of scar hyperplasia will occur at the skin grafting site after skin grafting. [0005] Therefore, how to solve the contracture of the skin graft after skin grafting and prevent the formation of scars is the technical...
