Provided are a surgical operation device for an endoscope, an endoscope, and an endoscope operational tool which, in a configuration where the endoscope and a treatment tool passed through two passages provided in an overtube can be operated in conjunction with each other, are capable of changing a field of view appropriate for detailed observation and treatment and improving efficiency of an operation. An endoscope (100) and a treatment tool (200) are passed respectively through an endoscope passage and a treatment tool passage of an overtube (300) to be inserted into a body wall. An advancing/retreating operational part (130) provided in a cable part (104) extending from a base end of an endoscope insertion part (102) of the endoscope (100) is disposed in a position adjacent to an operational part (204) of the treatment tool (200). The advancing/retreating operational part (130) includes a hook part (132) having an opening (134) and an advancing/retreating operation of the endoscope (100) can be performed by inserting the index finger of the right hand holding the treatment tool (200) into the opening (134). Thus, the advancing/retreating operation of the treatment tool (200) and the advancing/retreating operation of the endoscope (100) can be performed with only one hand operating the treatment tool (200). |
