Has the function of making the cavity stable. The operation time can reach 1-2h, and if the cavity is not stable, the fatigue of a doctor can be caused, and the accuracy of the operation of the doctor is influenced. The U-shaped suspension draw hook can better play the stability of the ostomy cavity.
Because the U-shaped drag hook 1 is a strip-shaped plate, the strip-shaped plate is attached to the gap, and the gap is favorably formed by dragging the tissue of the gap.
The U-shaped structure of the U-shaped drag hook 1 has the advantages that after the stretching end stretches into the gap, when the suspension end has an acting force to the outside, the U-shaped structure keeps the shape, and through the force conduction, the stretching end has an obvious stretching force in the same direction, so that the U-shaped drag hook is favorable for the position of an operation to be subjected to cavity creation, and the condition that an operator sees the inside is favorable. The atress of U type structure is special, for example when putting U type structure upright, U type opening sets up to left or right direction, and the heavy object is placed to the one end of U type, and the upper end is upwards drawn, and the lower extreme can drive the heavy object and upwards mention. For another example, when the U-shaped structure is placed upright with the U-shaped opening facing left or right, one hand is placed at the lower end and the upper end is lifted upward, and the hand is pressed downward with force, a significant upward pulling force is felt. Therefore, the U-shaped structure is arranged, and the extending end has the function of pulling the gap open under the action of force.
Moreover, the U-shaped retractor has stability compared with other structures, such as using a straight plate, if the extending end is controlled to be lifted by the suspension end of the straight plate, the first straight plate needs a fulcrum, so the straight plate cannot directly pull the tissue upwards in a suspension mode, the extending end can press downwards, if the extending end wants to press downwards, the suspension end needs to provide a fulcrum, such as providing a fulcrum by hand; second, if the straight plate is engaged through the fulcrum, it is only possible to pull open the internal space of the tissue, and the physician is outside and not good for observing the internal conditions.
