Wound protectors (also named incision retractors) are essential sterile surgical devices used to retract incision edges, isolate wound contamination, expand surgical visual field and reduce tumor cell implantation during laparotomy and laparoscopic procedures. The  manufacturer- Changzhou Haida Medical Equipment Co., Ltd. provides multi-spec HRA (TPU film open surgery type) and HRB (silicone minimally invasive trocar type) product lines, yet many clinical nurses, operating room purchasers and medical distributors lack standardized model-incision matching reference.This paper sorts out the parameter logic of HRA/HRB series wound protectors, lists complete specification-incision matching tables, and combines a large number of real clinical operation cases to form a systematic technical selection scheme, which can be used for hospital procurement reference, medical staff training and distributor product promotion material.
