Description

TECHNICAL FIELD

[0001] The utility model relates to neck lymphatic cleaning equipment technical field, specifically is a skin drag hook for neck lymphatic cleaning. BACKGROUND

[0002] In the operation of turning up the flap of the neck downward or backward, the traditional method is to use disposable rubber band to connect the scalp drag hook or use ordinary thyroid drag hook to pull the turned up flap. The scalp drag hook needs to be connected with a blood vessel clamp through a rubber ring and then clamped on the surgical drape for fixation, which is inconvenient to operate, and the rubber band is easy to break, causing blood splashing. The pulled flap is also not stable enough. The ordinary thyroid drag hook needs at least one assistant to continuously pull, which is easy to cause fatigue. The end of the drag hook is unstable, and the flap is easy to slip off.

[0003] A new type of abdominal surgery drag hook is disclosed in the patent with publication number CN201912146U. The patent specifically discloses a technical solution of "a new type of abdominal surgery drag hook, including a handle, three harrow type wide drag hooks, and a handle. The handle is provided with positioning holes on both ends and the harrow type wide drag hooks and the handle. The harrow type wide drag hooks and the handle are movably connected to the two ends of the handle through positioning pins". This technical solution achieves the technical effect of "greatly improving the surgical field, shortening the operation time, improving the operation efficiency, and reducing the patient's pain".

[0004] However, this patent uses a hook-shaped device to pull the flap during actual use, but the device has no other functions besides pulling, and an assistant is needed. When the main surgeon and the assistant do not cooperate well, the use effect is poor, and there is room for improvement.

[0005] Therefore, the patent with publication number CN210354787U discloses a new type of skin flap drag hook for breast surgery. The patent specifically discloses a technical solution of "a new type of skin flap drag hook for breast surgery, including a handle, a first pull rod fixedly welded on the left side of the handle, a cylindrical slot provided on the left end of the first pull rod, a second pull rod movably installed in the cylindrical slot, and an arc-shaped drag hook rotatably installed on the left end of the second pull rod. A first electric telescopic rod is fixedly installed on the right inner wall of the cylindrical slot". This technical solution achieves the technical effect of "the skin flap drag hook for breast surgery in the utility model can adjust the bending angle of the arc-shaped drag hook, so that the arc-shaped drag hook is more firmly hooked and pulled during the lifting process, to prevent the skin flap from slipping off the arc-shaped drag hook, which is conducive to ensuring the normal progress of the operation. The length of the entire skin flap drag hook device can be easily adjusted by people, which is conducive to the adjustment and use according to actual needs".

[0006] But the device in the actual use process although liberated the assistant's both hands, but the equipment cannot good assembly use, there is the room of improvement. The utility model discloses a content
