TREATMENT DEVICE AND TREATMENT TOOL

摘要

A medical treatment instrument (12) includes a first treating portion (52), a second treating portion (54) and an operation portion (32). The first treating portion includes holding members (62, 64) to hold the target living tissues and an energy output unit (82b, 84b) which join the target living tissues when the target living tissues is applied thereto from the energy source. The second treating portion is interposed between the target living tissues and denatures the surfaces of the target living tissues in contact with the second treating portion. The operation portion (32) has a function of operating the holding members so that the holding members moves relative to the other. The energy output unit and the second treating portion are able to detect at least one of biological information regarding the living tissues held by the holding members and biological information regarding the living tissues between the holding member and the second treating portion, and control energy output from the energy source to the energy output unit and the second treating portion is controlled on the basis of the biological information regarding the living tissues obtained by the energy output unit and the second treating portion.
