The utility model belongs to the technical field of
medical instruments, and discloses a pair of
radio frequency bipolar scissors for treating haemorrhoids, which comprises two cutter bodies, the two cutter bodies are oppositely arranged and can clamp tissues, the opposite surfaces of the two cutter bodies are
cutting parts,
electrode plates are arranged on the
cutting parts, the cutter bodies are integrally bent in an arc shape, and the
electrode plates are arranged on the cutter bodies. The face, making contact with the tissue
cutting face, of the cutter body is a front face, the other face of the cutter body is a back face, the arc bending direction of the cutter body faces the back face, and when the front face of the cutting part is attached to the tissue cutting face, one part makes contact with the tissue cutting face, and a space is formed between the other part and the tissue cutting face. The cutting part is bent at an arc angle, and a tangency point is closer to
rectum tissue, so that the contact area with
normal tissue is reduced, and a better visual field is provided for an operation area. Space exists between the front face of the cutting part and the tissue cutting face, the contact area of the front face of the cutter body and the tissue cutting face is reduced, and therefore heat transferred to non-
target tissue by the cutting edge is reduced.
