摘要：
A device for insertion of a flexible needle or other such instrument into a tissue incorporating a collapsible support guide which supports that part of the needle which has not yet penetrated the tissue preventing it from buckling and an arrangement which pulls the needle from its proximal end to provide sufficient force for the penetration process. The collapsible support guide can be a pair of flexible strips connected along their length and enclosing the needle along its uninserted length in order to support it with a mechanism at the distal end of the device to peel the strips from the needle as it is inserted. Insertion can be achieved by a pair of rollers engaging and advancing the strips distally. Alternatively a telescopic support tube can be used to support the needle the tube collapsing telescopically as the needle is inserted to maintain clearance above the needle.
