ABSTRACT:
A high frequency treatment device is provided for high-frequency medical treatments including blood stanching. The device comprises an insertion member and a pair of jaws each representing a longitudinal direction, taking on an electrode function along an entire longitudinal region of each jaw, and having a gripping surface. In the device, a link member holds the jaws to be opened and closed in a direction allowing their gripping surfaces to be opposed to each other and links the jaws to a tip of the insertion member to keep electrical insulation between the jaws. An electrical short circuit between the jaws is prevented even when the jaws are mutually closed. A power line applies a high frequency voltage to the jaws via the link member to cause a high frequency current to flow through the jaws. An operation wire transmits open/close movements to the jaws via the link member.
