Flap traction device used for full-ectomy of mammary glands

Abstract

The invention discloses a flap traction device used for full-ectomy of the mammary glands. The flap traction device comprises a handle and a plurality of traction units arranged on the handle, whereineach traction unit comprises a slider and a drag hook, each slider can axially move along the handle, each drag hook is arranged on the corresponding slider in a hinging mode, during the surgery process, since the plurality of drag hooks are arranged, the number of position points for lifting the free flaps is increased, one assistant can simultaneously complete the lifting for the flaps on a plurality of position points by two hands by utilizing two flap traction devices, therefore, human resources and space resources are greatly saved, the operation of surgery doctors is facilitated, with the traction device provided by the invention, the defects of the slippage and the unsatisfactory exposure of the surgery field caused by lifting of fingers are also overcome, and thus the continuity and safety of the surgery are guaranteed. In addition, the positions of the drag hooks are adjusted along with the movement of the sliders, the drag hooks are hinged to the sliders, the positions of the drag hooks are adjusted or the direction of the drag hooks is stirred, so that the distances among the lifting points are enlarged or shortened, and thus the use is convenient and flexible.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a skin flap pulling device for total mastectomy. Background technique [0002] Breast cancer surgery includes mastectomy and lymph node biopsy / dissection. Among them, total mastectomy is currently the most commonly used method of mastectomy, usually with the tumor as the center and a distance of 2-3 cm from its border, making a horizontal fusiform incision longer than 15-20 cm including the nipple and areola. After that, the free skin flap was started, up to the subclavian, down to the upper edge of the rectus abdominis tendon sheath, inside to the parasternum, and outside to the front edge of the latissimus dorsi. When the skin flap is strong, the assistant needs to use the retractor to lift up the cut flap as much as possible, and the operator presses the mammary glands downward. The direction of force is opposite to fully expose the gap between the mammary glands and the skin. ...

AI Technical Summary

Problems solved by technology

The method commonly used in current clinical operations is that at least two assistants are required to clamp the skin with tissue forceps or fingers, and lift the flap up to achieve full exposure. However, the use of tissue forceps or direct lifting with hands has the following disadvantages: First, Two assistants have a total of four hands. The function points of the forceps and hands are very narrow and the number is limited, which
