An endoscope forceps lifting device. The bottom end of the endoscope forceps lifting device communicates with an instrument channel and is provided with a hinge part that is hinged to a head base, and the top end thereof is provided with a positioning bayonet (20); and a guide slot (21) is formed between the instrument channel and the positioning bayonet (20). Before the endoscope forceps lifting device lifts forceps, a positioned part may be guided into the positioning bayonet (20) by means of the guide slot (21) and be laterally spaced and positioned. In the endoscope forceps lifting device, the positioned part may be directly positioned by the positioning bayonet (20), the positioned part, such as a catheter or guide wire (4), may be precisely and effectively positioned during the process of lifting forceps using the forceps lifting device and during a surgery, so that a handling appliance may be effectively fixed and precisely adjusted, thereby reducing surgery risks, and improving the usage convenience. Also disclosed are a corresponding endoscope head part and duodenoscopy system. |
