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.

Designed exclusively for pediatric minimally invasive procedures, the Single-Use Optical Trocar from Changzhou Haida Medical Instrument Co., Ltd. delivers precision, safety, and reliability for young patients. With a cannula diameter of 5.8mm and a working length of 75mm, this device is engineered to match the unique anatomical needs of children, ensuring minimally invasive access while maximizing surgical control. As a disposable medical device, it eliminates cross-infection risks associated with reusable trocars and streamlines operating room workflows .  This optical trocar with size 5mm-75mm has been recently launched from haida medical.
