Endoscope electrocoagulation and suction device

The utility model relates to an endoscope electrocoagulation and suction device. The endoscope electrocoagulation and suction device comprises a suction device rod, a handle, a connecting wire and a plastic hose. The suction device rod, the handle and the plastic hose are hollow and are communicated with one another. A switch is arranged on the handle. The suction device rod and the handle are not on the same straight line. The suction device rod is composed of an electrocoagulation pipe, a metal layer and a plastic protective layer from inside to outside in sequence. The inner diameter of the electrocoagulation pipe is larger than 2 mm. The outer diameter of the plastic protective layer is smaller than 4 mm. An angle ranging from 20 degrees to 40 degrees is formed between the left end section of the electrocoagulation pipe, the metal layer and the plastic protective layer and a plumb line. The left end of the electrocoagulation pipe extends to form an L-shaped electrocoagulation head. The two parts, perpendicular to each other, of the electrocoagulation head are smoothly connected. The endoscope electrocoagulation and suction device has the advantages of being capable of conducting suction and electrocoagulation simultaneously, conforming to the body structure of a patient and operation habits of doctors, and being convenient to use, simple in structure and worth popularizing.
