Background
Breast cancer is the most common malignancy among women worldwide. Breast cancer has also become the most common malignancy in women in china. Currently, surgery remains one of the major therapeutic approaches for early breast cancer. According to the american cancer society, 95% of breast cancer patients in stages I and II receive surgical treatment, of which 61% receive breast conserving surgery and 34% receive mastectomy; of the breast cancer patients in stage III, 88% will receive surgical treatment, with 20% receiving breast conserving surgery and 68% receiving mastectomy. Accordingly, mastectomy remains one of the most prominent means of breast cancer treatment.
The breast is composed of skin and subcutaneous glandular tissue. Mastectomy usually requires a fusiform skin incision of about 15-25 cm in length on the skin of the breast and extensive dissociation of the flap, and usually during the operation, the surgeon first performs dissociation of the flap on one side of the incision and then dissociates the flap on the other side of the incision. Under the condition of the existing surgical instruments, the breast resection needs to be performed by cooperation of at least three surgeons, wherein a main surgeon holds an electric knife or a scalpel to incise and separate the skin and the tissue connected with the subcutaneous gland, and the subcutaneous gland is peeled and resected from the lower part of the skin; the first assistant assists in pulling the subcutaneous glandular tissue to keep a certain tension with the skin all the time, so that the skin and the mammary gland tissue can be conveniently separated from the lower part of the skin, and the operation of hemostasis and the like can be completed by cooperating with a doctor knife; the second assistant holds the skin or subcutaneous tissue with the surgical instrument, pulls the skin, maintains a certain tension of the skin with the glands of the subcutaneous breast, and completely unfolds and maintains the tension of the already separated skin, facilitating full exposure of the surgical field and facilitating further resection of the glands of the subcutaneous breast.
The existing skin traction apparatus mainly comprises a hemostatic forceps, a tissue forceps, a skin draw hook and a handkerchief forceps. To keep the skin adequately pulled, one surgical instrument is typically held every 2-3 cm at the edge of the incised skin, so that the skin on each side of the fusiform skin incision needs to hold between 6 and 8 surgical instruments. Each surgical instrument is provided with a finger ring, an operator can hook fingers on the finger ring to pull, and each finger can pull one surgical instrument, so that an assistant has to use fingers of two hands to pull the instrument, and no hand can be used for assisting a main surgeon in performing other surgical operations. Regardless of the use of hemostats, tissue clamps or tissue clamps, surgeons are required to clamp the instruments to the skin or subcutaneous tissue, each clamping of an instrument requires a certain amount of time, which is time consuming. However, while maintaining the quality of the surgery, shortening the time of the surgery has always been a goal sought by surgeons. If the existing skin retractor is used, the tip of the retractor can directly hook the skin, so that the time consumed for clamping tissues is saved, but the defect is also obvious, the handle is a straight handle, and each hand of an assistant can only hold one skin retractor, so that the skin retractor with the whole length is difficult to complete even if two hands are used together.
The skin stretching instruments used in the existing mastectomy are somewhat complicated and time-consuming to operate, and must be used with both hands of the surgeon to accomplish the stretching of the skin and the full exposure of the operative field.
Therefore, it is necessary to design a new skin retractor for overcoming the defects in the prior art.
