Technical Field
The utility model relates to the field of medical instruments, in particular to a blunt stripping device for embedding a scalp dilator.
Background
Skin soft tissue dilation is an advanced treatment specific to plastic surgery. It was first applied to the treatment of cicatricial alopecia, and then it was applied to the sites where the general body surface defects need to be repaired with additional skin. Various scars, especially after burns, are the most commonly used disease species for skin soft tissue dilatation. The principle is that the skin soft tissue dilator is implanted under normal skin soft tissue near pathological changes, and the capacity of the dilator is increased by injecting liquid into the dilating capsule discontinuously, so that the dilator generates pressure on the surface skin soft tissue. And the scalp is the best site for dilator application.
The operation steps for embedding the scalp dilator mainly comprise: selecting a normal scalp part near a lesion area as an implantation part, positioning a skin incision at the outer side of a free edge or a scar edge of a skin flap to be formed in the future, cutting the scalp, separating the scalp layer by layer to the deep surface of the calotte aponeurosis, using a curved forceps to blunt and peel off the gap between the calotte aponeurosis and the periosteum to form a cavity gap which is 1-2cm larger than an expansion capsule, turning over the free calotte aponeurosis, using bipolar electrocoagulation to stop bleeding exactly, implanting an expander and tiling.
At present, bending forceps are mainly used clinically to strip the gap between the aponeurosis and the periosteum and are used for embedding a scalp expander in the next step. When the expansion bag is removed in an blunt way, the skin is required to be removed fully, generally the peeling is larger than 1cm of the periphery of the expansion bag, if the peeling lacuna is insufficient, the expansion bag is not flat, so that a sharp corner is formed, the sharp corner breaks the scalp, and the local skin flap is easy to cause overlarge tension, so that the skin flap is necrotized due to blood supply disorder. The traditional stripping instrument is used, so that the operation process is long, the bleeding is more during the operation, and the stripping is insufficient.
