Preferably, the movable rod and the first protrusion are of an integral structure.

Preferably, the handle is an elastic handle.

Preferably, the traction mechanism includes the connecting rod, the connecting rod with the outer tube cooperatees, the bottom of connecting rod is connected with the dwang, the rotatable connection in bottom of dwang the fixing base, the upper end of connecting rod is connected with the knee.

Preferably, the bent rod is an elastic rod.

The utility model provides a liver operation is with tractive ware under peritoneoscope, beneficial effect lies in:

drive the movable rod through the handle and rotate, interlock each other at external thread and internal thread for the movable rod slowly rebound, the movable rod removes and promotes the drawing mechanism and slowly removes, makes the outer tube of drawing end stretching out of drawing mechanism, and drawing end drawing liver of drawing mechanism stops to rotate the movable rod, and drawing mechanism does not take place to remove, and drawing mechanism stretches into slowly, can not harm the liver.
