A kind of dilator exposed wound repair method

Abstract

The invention discloses a method for repairing a wound surface exposed by a dilator, which comprises the following steps: step 1: release the water in the expansion sac; step 2: remove foreign matter, blood accumulation, effusion, and necrotic tissue in the expansion sac; Step 3: Indwell a negative pressure suction tube on the bottom of the dilator. The outlet of the negative pressure suction tube is selected at the normal skin about 1 cm outside the edge of the dilator closest to the breach. The outer surface of the negative pressure suction tube is The end is connected to a negative pressure device; step four: a carbon fiber dressing is placed between the base surface of the exposed wound of the dilator and the dilator; step five; step six; step seven. This wound repair method makes full use of the high affinity between carbon fiber and human tissue, which can not only isolate the wound tissue from the foreign body of the dilator, but also accurately repair the exposed weak and damaged skin by forming a carbon fiber-human tissue complex, which can repair the previously unrepairable skin. The dilator exposes the wound surface and effectively saves the expanded skin flap, thereby completing the therapeutic purpose of the expanded skin flap.

Description

technical field [0001] The invention relates to the technical field of medical plastic surgery, and more specifically, the invention relates to a method for repairing a dilator-exposed wound. Background technique [0002] In plastic surgery, because expanded flaps can provide enough full-thickness skin that is close to the skin color and texture of the recipient area, and it reduces the damage to the donor area compared with skin grafting, skin soft tissue expansion (skin soft tissue expansion) Skin dilatation for short has become a widely used technique in plastic restorative treatment. However, the first-stage complications after dilator embedding have always been a difficult problem, with an incidence rate of about 10-70%. In the face of rupture of the expanded skin flap and exposure of the dilator due to these reasons, doctors are often at a loss what to do. Once such a situation occurs, most of the time, the dilator can only be removed in advance, and it is difficult t...

However, the first-stage complications after dilator embedding have always been a difficult problem, with an incidence rate of about 10-70%. In the face of rupture of the expanded skin flap and exposure of the dilator due to these reasons, doctors are often at a loss what to do

Once such a situation occurs, most of the time, the dilator can only be removed in advance, and it is difficult to achieve the expected therapeutic effect
