[0002] Surgical retractors are instruments used in surgery to retract and expose the surgical field. They typically consist of a hook body and a handle. Depending on their application, surgical retractors can be classified into various types, such as skin retractors, thyroid retractors, and abdominal retractors. They are mostly made of stainless steel or titanium alloy. Surgical retractors are primarily used to retract skin, muscles, or internal organs to fully expose the surgical site. For example, S-shaped retractors are commonly used to retract the abdominal wall in abdominal surgery, while rib retractors are used to open the intercostal spaces in thoracic surgery. Proper use of surgical retractors can reduce blind spots in the surgical field and improve surgical precision.

[0003] Existing surgical retractors are generally either a one-piece fixed structure or an expandable scissor-like structure. Fixed structures are more laborious to use and inconvenient to adjust, while scissor-like structures tend to leave residue in crevices and other places after use, making them difficult to clean and generally inconvenient to disassemble, making cleaning and disinfection difficult in actual use.
