Bone graft delivery to the intervertebral space is a consistent source of frustration. The devices available jam, deposit graft material at the end of the tool blocking cage insertion and don’t allow the surgeon to take advantage of the entire area of prepared disk space.
Our first product solves these problems and allows application of autograft and/or bone graft substitute smoothly and efficiently, cutting the time to fill the prepared disk space to several minutes or less. It allows inoculation of bone graft to the most collapsed disk space. Due to its unique biportal extrusion, it applies the graft to the entire prepared disk space leaving a natural void for fusion cage application. This tool allows the surgeon to control the volume of graft material application instead of being limited by the wrong implement.
TOOL SPECIFICS -
Cannula Volume: 7 ml
Funnel Volume: 10 ml
This device has portals on either side which double the exit zone for extruded material and a ramp at the internal end which directs the graft material out of the cannula.
The rectangular crossection of the device is twice that of a round (8mm diameter) cannula which improves the flow characteristics of bone graft material by 40%.
