Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a breast right-angle retractor. Background Art

[0002] The breast retractor is a device specifically designed for breast surgery. Its right-angled shape facilitates retraction and exposure during surgery. This retractor allows for better visualization of the surgical area, improving surgical accuracy and safety.

[0003] In the related art, most general hospitals currently use square hooks and thyroid retractors to expose the surgical field during breast surgery.

[0004] However, the use of the above method makes it impossible for the surgeon to immediately subjectively judge the thickness of the skin, which reduces the smoothness of the operation. When the above method is not feasible, the surgeon will use straight forceps or tissue forceps to lift the skin, which is inconvenient and easy to damage the skin or destroy the subcutaneous tissue. There is currently a lack of breast retractors in the market. The existing breast retractors are basically made of a one-piece structure of manufacturing materials. They need to be constantly disinfected when reused, which is not convenient for reuse. Utility Model Content
