Abstract
Official abstract text for this publication.
An insertion instrument for inserting an implant includes an elongated main body having a proximal handle and a distal portion that selectively couples to the implant. A plunger is slidably engaged in a central passage of the elongated main body configured to fix the implant to the elongated main body by selectively filling the central passage within the distal portion. A hex nut driver is concentrically located about the plunger and elongated main body to deploy an actuation plunger of the implant. The proximal handle portion of the main body includes a staggered path therethrough for accepting a tab of the plunger therein. Advancement and retraction of the plunger tab within the staggered path alternates the insertion instrument between an unlocked position configured to mount the implant on the distal portion of the elongated main body, a locked position configured to lock the implant on the distal portion, and a deployed position configured to secure the implant.
First claim
Opening claim text (preview).
What is claimed is: 1 . An insertion instrument for inserting an implant, the insertion instrument comprising: a handle portion connected to an elongated main body extending distally therefrom, the elongated main body having a distal portion configured to attach to the implant and a bore extending therethrough; and a plunger portion extending from a plunger knob disposed proximally to the handle portion and through the bore of the elongated main body, wherein the plunger comprises a plunger tab being received within a staggered path disposed on the handle portion, and wherein movement of plunger tab within the staggered path alternates the insertion instrument between an unlocked position, a locked position, and a deployed position.
