Abstract: The invention provides a medical instrument with angle adjustment device, including a guidewire output portion, a guidewire guide portion, an adjustment control portion and traction wires. The guidewire output portion is bendable relative to the guidewire guide portion. The guidewire output portion is provided with a guidewire output hole. One end of each traction wire is connected to a proximal end of the guidewire output portion, and the other end of the traction wire is connected to a bending control member of the adjustment control portion. The adjustment control portion controls a bending angle of the guidewire output portion through the traction wire. The ends of the plurality of traction wires are evenly distributed along the guidewire output portion. The positions and quantity of traction wires are set to enable a medical instrument having a distal end with an adjustable bending degree to adjust angles in various directions as required.
