The utility model relates to a pair of attached hydrothermal biopsy forceps for an endoscope. The pair of novel attached hydrothermal biopsy forceps comprises a pair of novel attached hydrothermal biopsy forceps for an endoscope, the clamp comprises a clamp head, a clamp body and an operating handle, one end of the clamp body is fixedly connected with the operating handle; wherein one end of the clamp body is fixedly connected with the clamp head, the other end of the clamp body is fixedly connected with the clamp head, the clamp body is hollow, a water injection port is formed in the clamp body and communicated with the inside of the clamp body, a water injection part of the clamp body is located between the water injection port and the clamp head, the outer wall of the water injection part is closed, and a water outlet is formed in the lower end of the water injection part. In this way, under the condition that a hollow hose is not used, it can be guaranteed that cleaning fluid in the injector is conveyed into the forceps body through the water injection port, so that the bleeding or seepage part is flushed, the bleeding point is accurately judged, and then the hemostatic forcepsare used for rapidly and accurately clamping the bleeding point and conducting electric coagulation hemostasis.
