Drag hook for mastectomy

Abstract

The invention discloses a surgical drag hook, and a drag hook which consists of the surgical drag hook for mastectomy. The surgical drag hook comprises a rod body, a sharp hook part and a rotary rod, wherein the rotary rod can be withdrawn into a groove of the rod body when being positioned in a first position; and when the rotary body is positioned in a second position, the hook part is withdrawn into a groove of a protection cap. The drag hook for mastectomy comprises an arced rack and a plurality of surgical drag hooks, wherein the interior of the drag hook is hollow; an arced opening is formed in the lower part of the drag hook; the plurality of the surgical drag hooks are movably connected with the arced rack; and a sphere which can be contained and slide inside the raced rack is arranged at the upper end of each surgical drag hook. According to the surgical drag hook, a small sharp hook is used for puncturing the flap and used for lifting, thereby effectively ensuring that the flap is in the constant tension state, no wrinkles which can affect the operation are generated, the hook body can be sealed up through the protection cap, and the flap is prevented from dropping off from the hook body. When the drag hook is used, flaps on two sides of a notch are lifted from the left side and the right side by using two groups of the drag hooks respectively, and the operation can be realized by only one assistant.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a retractor for mastectomy and the combination with the retractor frame. Background technique [0002] During mastectomy, an electric knife is used to dissect the free skin flap sharply starting from the subcutaneous fat tissue. As the skin flap gradually frees up, the flap needs to be pulled up to expose the remaining tissue to continue the operation. At present, multiple assistants use hemostatic forceps Or towel forceps to pull up the skin flap, the alveolar structure of the hemostat and towel forceps will cause great damage to the skin, and will leave a large area of ​​permanent scars after the operation, and once the skin flap is loosened during the operation, it is likely to Contact with the electric knife can cause burns. And the operations of multiple assistants affect the operative field of view, which reduces the operative efficiency. [0003] Although there are some re...
