Abstract:
According to a medical traction device containing a polymer molded article having biocompatibility as a weight for traction of a living tissue to be resected under observation with an endoscope, and a medical traction equipment containing the medical traction device and a grasping member connected to each other, such a medical traction device or traction equipment is provided that in ESD in a digestive tract, a dissected living tissue is efficiently removed from the operative field also in a direction that is different from the moving direction of the endoscope, thereby maintaining the field of view, and the procedures are thus performed safely and rapidly.
