摘要
A surgical tool for inserting a spile or plug into the punctal opening of a meatus such as a lacrimo-nasal canaliculus. The tool includes a distal end having a plug-carrying structure which includes distally extending rod for engaging an axial bore in the plug, and an abutment having a radial prominence supporting a penetration-resisting bearing surface which prevents over-insertion of the plug by contacting tissue surrounding the punctal opening. The abutment can be shaped and dimensioned to provide effective and comfortable penetration resistance while affording ample visibility to the surgeon user. The rod can be axially withdrawn through a rod tracking tube having a precisely dimensioned central lumen restricting off-axis movement of the rod. The abutment can be fixed to the rod or detached from it.
