[0002] Retractors are medical equipment and surgical tools used to assist in the assembly and implantation of related hip prostheses. Common classifications include the following: thyroid retractors, also called right-angle retractors, are flat hooks and are often used to pull and expose the thyroid area. They are also commonly used in other surgeries to retract the skin, subcutaneous tissue, muscles, and fascia. Abdominal retractors, also called square hooks, are wider and smoother hooks used for larger abdominal surgeries. Skin retractors, also called claw retractors, have a rake-like appearance and are used for skin retraction in shallow surgeries. Shaped retractors, also called curved hooks, are deep abdominal retractors. , used for deep thoracic and abdominal surgeries, divided into large, medium, small, wide and narrow. Pay attention to the correct use of the retractor. The automatic retractor is a self-fixing retractor, also known as a self-sustaining retractor, such as a two-leaf and three-leaf automatic retractor. It can be used for surgeries in the abdominal cavity, thoracic cavity, pelvic cavity, waist, cranial and brain areas.
