Description

Sucking disc formula drag hook for abdominal cavity operation

Technical Field

The utility model relates to the technical field of surgical operating instruments, concretely relates to sucking disc formula drag hook for abdominal cavity operation.

Background

In a surgical operation, the retractor is mainly used for pulling open and fixing a wound or a cavity opening opened by medical staff in the operation, so that the medical staff can conveniently perform the operation on a focus in a patient body; during abdominal cavity surgery, because of the large number of organs in the abdominal cavity of a human body, the drag hook is needed to pull open the wound on the body surface of a patient, and the drag hook is also needed to displace the viscera to be operated to a certain extent so as to facilitate the operation of medical staff; it is especially important when the canceration tumor excision is carried out on organs such as liver, spleen, stomach and the like; however, when the existing drag hook is used to displace the organ to be operated, the organ often slides on the hook head part of the drag hook due to the lubrication effect of the body fluid in the abdominal cavity of the human body and the physiological shaking generated when the medical staff holds the drag hook to pull the arm, thereby affecting the normal operation of the operation.

To solve this problem, in patent documents such as those disclosed in domestic application No. 201511023632.0 and application date 20151230: the length-adjustable universal headstock fixing draw hook can reduce the need that medical personnel hold the draw hook during operation by fixing a draw hook arm, thereby improving the stability of the draw hook during operation; however, in the technical scheme, the problem that the drag hook is in surface contact with the viscera so that the viscera tends to move is not completely solved, and the fixation of the relative position between the viscera and the drag hook cannot be ensured.
