Wound closure techniques


Wound healing

  • the inflammatory phase
  • the proliferative or granulation phase
  • the differentiation or maturation phase

Surgical techniques

local anesthesia


在这部分提到了一个技巧“The blade is simultaneously angled to create a slight bevel”,其目的在于“The bevel created by the angled bias of the blade facilitates tissue eversion when the wound margins are approximated”, 故这个bevel应该是有上端斜向病变组织,下端斜向正常组织,切除病变缝合时皮肤会拱起形成外翻:

  • single-prong tissue hook在缝合及潜行分离中的应用有助于减少组织损伤,在潜行分离中利用中指感受分离深度有助于保持在同一层面:

  • inflammatory response: Chromic and plain gut sutures are associated with significant tissue reactions;a variety of synthetic absorbable suture fibers are absorbed by simple hydrolysis, which is associated with limited inflammation. Nonabsorbable fibers do not undergo local degradation and elicit the least inflammatory response.
