Flipp tack pusher

摘要

A device and method for pushing an anchor through a bore in a bone is provided with an elongated shaft, an anchor carrying assembly disposed at a distal end of the shaft for carrying an anchor, and a plunger disposed in the elongated shaft. The plunger is movable relative to the elongated shaft. First, threads are attached to the anchor. Then, the anchor is positioned in the anchor fastener, and the elongated shaft is placed next to the bore in the bone. Next, the plunger is inserted into the elongated shaft, and a force is exerted to on the plunger to move it in direction of the distal end of the elongated shaft such that a distal end of the plunger comes into contact with the anchor and pushes the anchor through the bore in the bone. Then, the threads attached to the anchor are pulled to position the anchor.

1. A method for pushing an anchor through a bore in a bone, comprising the steps of:
attaching threads to the anchor to be pushed; positioning the anchor in an anchor carrying assembly disposed at a distal end of an elongated shaft, wherein an outer diameter of said anchor carrying assembly is not smaller than an inner diameter of the bore in the bone; placing the distal end of said elongated shaft next to the bore in the bone; inserting a plunger into said elongated shaft; exerting a force on a proximal end of said plunger to move the plunger in direction of the distal end of the elongated shaft such that a distal end of said plunger comes into contact with the anchor disposed in said anchor carrying assembly and then pushes said anchor through and out of the bore in the bone; and pulling on the threads attached to the anchor to position the anchor in a position secured to the bone; wherein the threads attached to the anchor are arranged in a groove provided on an outer wall of said anchor carrying assembly, wherein the groove does not extend to a proximal end of the elongated shaft.
