Description

Technical Field

[0001] The utility model relates to the technical field of breast laparoscopic surgery instruments, in particular to a skin flap separation shovel for breast laparoscopic surgery. Background Art

[0002] Breast cancer is a common malignant tumor in women, and radical surgery is still the main treatment method. Radical mastectomy or modified radical mastectomy is widely used in my country. Regardless of the surgical procedure, the breast skin and subcutaneous fat layer must be separated first to form a flap. Various surgical procedures have high requirements for the free flap. If the flap is too thin, the skin and the arteries and veins underneath it are easily separated, resulting in poor blood circulation of the flap and causing flap necrosis. If it is too thick, it may cause residual cancer and postoperative tumor recurrence. It is generally believed that the free thickness of the flap during surgery is 3-4mm. The flap near the tumor can be appropriately thin, and the subcutaneous fat layer of the rest of the flap should retain an appropriate thickness to preserve the vascular network inside. The thickness of the flap should be as uniform as possible, that is, a "thin trapezoidal flap with thin cutting edges and thick periphery" is formed;

[0003] Traditional flap separators used in laparoscopic breast surgery have some disadvantages. During human surgery, it is often necessary to first make an incision in the human body, separate the flap at the incision, and then implant a catheter and an infusion seat. However, when using the flap separator in traditional technology, the blade is straight, which makes it difficult for the blade to fit the surface skin of the human body, making it difficult to separate the breast skin from the subcutaneous fat layer.
