This invention discloses a controllable dripping bipolar ablation hemostatic forceps, relating to the field of hemostatic forceps technology. It includes a clamping component, a connecting base with a connecting member on one side, a first forceps handle fixed to one side of the connecting base, a second forceps handle fixed to one side of the connecting base, and a cooperating component. Through the coordinated design of the clamping component and the cooperating component, it effectively solves the shortcomings of existing controllable dripping bipolar ablation hemostatic forceps, such as poor operability, low surgical efficiency, and insufficient surgical field clarity. It abandons the cumbersome control method of externally driven dripping components, automatically and precisely adjusting the dripping volume according to the clamping force of the operator. This avoids insufficient dripping leading to tissue carbonization when the clamping force is high and the ablation intensity is high, or excessive dripping leading to fluid accumulation in the surgical field when the clamping force is low and the ablation intensity is low, ensuring the ablation and hemostasis effect. It eliminates the need for frequent manual adjustment of dripping parameters by medical staff, reducing the operational burden.
