Abstract
In a link device for surgical tool and a surgical tool suitable for used with an endoscope, the diameter of an insertion section can be made narrow. A multi-free forceps (surgical tool) is used as a soft surgical tool for use with an endoscope. The multi-free forceps comprises a link device for surgical tool that is inserted into a human cavity. The link device for surgical tool comprises a pipe-like insertion section, a surgical section that connects to a tip of the insertion section, and a control section that controls the surgical section. A base side of a deviating link member is securely connected to a first control axis member, and a base side of the deviating link member that forms the surgical section side extends in parallel to the first control axis member at a position that is further to the inside than the outer peripheral face of the insertion section, while deviating further to the outside of the diameter direction than the central axis of the first control axis member.
