[0002] Bipolar forceps are specialized instruments with two independent forceps arms working together as their core structure, integrating functions such as precise positioning, insulation protection, and external device compatibility. They are mainly used in the medical field for high-frequency electrocoagulation hemostasis and tissue processing.

[0003] Chinese Patent Application No. 202421853412.5 discloses a guideable bipolar forceps device, including a shell with a mounting block. Left and right forceps are symmetrically arranged on the mounting block. Guide posts and guide grooves are respectively arranged on the side walls of the left and right forceps close to each other. Due to the setting of guide posts and guide grooves, the bipolar forceps device has a guiding function, which can realize the accurate alignment of the tips of the left and right forceps, prevent skewing, and also effectively control the blood vessels from being crushed due to excessive force causing the forceps tips to close too tightly.
