1. A medical instrument guiding device comprising:
- a guide member configured to penetrate a body wall and to be inserted in a body cavity;
an endoscope insertion hole which is provided in the guide member and into which an endoscope that performs observation in the body cavity can be inserted so as to be freely movable back and forth;
a treatment tool insertion hole which is provided in the guide member and into which a treatment tool that inspects or treats a diseased site in the body cavity can be inserted so as to be freely movable back and forth; and
a back-and-forth movement transmission mechanism which is configured to transmit back-and-forth movement of the treatment tool to the endoscope, is provided in the inside of the guide member, and includes a rotation member which has a rotation axis that three-dimensionally intersects with a longitudinal axis of the treatment tool insertion hole and rotates according to the back-and-forth movement of the treatment tool.

Abstract
A medical instrument guiding device (outer tube) to be tapped into a body wall includes: an endoscope insertion hole for inserting the endoscope; a treatment tool insertion hole for inserting the treatment tool; and an interlocking mechanism for moving the endoscope back and forth in interlock with the back-and-forth movement of the treatment tool. The interlocking mechanism includes an endoscope-side roller contacts with an endoscope insertion part and moves in interlock with the endoscope insertion part, and a treatment tool-side roller which contacts with a treatment tool insertion part and moves in interlock with the treatment tool insertion part, and those rollers rotates in interlock with each other. In response to the movement of the treatment tool insertion part, the treatment tool-side roller and the endoscope-side roller rotate in an opposite direction to move the endoscope insertion part.
