A triple three-way valve device comprises: a valve body ( 1 ) having a distal end and a proximal end, wherein the proximal end of the valve body ( 1 ) is connected with a control knob ( 2 ) that is radially rotatable relative to the valve body ( 1 ); and a valve rod ( 3 ) having a distal end and a proximal end, wherein the valve rod ( 3 ) is provided within the valve body ( 1 ) and is fixedly connected with the control knob ( 2 ). The distal end of the valve body ( 1 ) is connected with a seat body ( 4 ), which is connected with a plurality of liquid passages and a high pressure pipe passage; a selection member ( 5 ) provided at the distal end of the valve body ( 1 ), wherein, depending on the position of the control knob ( 2 ), the selection member ( 5 ) selects the communication relationships between the plurality of liquid passages of the seat body ( 4 ), the high pressure pipe passage and the valve rod. With the triple three-way valve device, angiocardiography surgery is simplified, and surgery safety and efficiency are improved. |
