MEDICAL INSTRUMENT INSERTION DEVICE AND MEDICAL INSTRUMENT INSERTION DEVICE SYSTEM

摘要

A medical instrument insertion device and a medical instrument insertion device system, enabling an insertion section to be reliably advanced in a stable state in a body by using a simple mechanism. The medical instrument insertion device has a spiral structure section provided on an elongate insertion section (10); a holding section (30) for holding the insertion section (10) so that the insertion section (10) can be advanced and retreated in the direction of a predetermined axis; and a rotation drive section (20) for rotating the holding section (30) about the predetermined axis. The construction improves operability of the insertion of the insertion section (10), which enables the insertion section (10) to be reliably inserted into a body cavity without requiring an operator to perform complex operation and to be skilled.
