Abstract
An endoscope treatment tool insertion-extraction system is provided with an endoscope having a forceps channel, and a treatment tool unit having a treatment tool that can be inserted and extracted through the forceps channel; and the treatment tool unit is provided with an insertion-extraction mechanism which carries out feeding into or drawing out of the treatment tool through the forceps channel, and a driving section that drives this insertion-extraction mechanism.
Claims24
An endoscope treatment tool insertion-extraction system provided with an endoscope having at least one forceps channel, and at least one treatment tool unit having a treatment tool that can be inserted and extracted through said forceps channel, wherein:
- said treatment tool unit is provided with an insertion-extraction mechanism which carries out feeding into or drawing out of said treatment tool through said forceps channel, and a driving section that drives this insertion-extraction mechanism;
- said insertion-extraction mechanism is provided with a rotation member that winds said treatment tool, and a conversion mechanism that converts a driving force of said driving section into a rotation force of said rotation member, so that an axis of rotation of the driving section is non-parallel to an axis of rotation of the rotation member;
- said treatment tool is provided with an operating section on a rotation axis of said rotation member;
- and
- teeth are formed on the outer circumference of said rotation member, and said conversion mechanism is a gear that meshes with said teeth.
