Biomaterial delivery device

摘要

A biomaterial delivery device includes an elongated handheld powder storage conduit with proximal and distal ends and a bore having a central axis. The proximal end is closed by a movable powder dispensing actuator, and the distal end is closed by an openable sealing nib moveable from its closed to its open position by force upon the actuator. The distal end has a distally-projecting powder discharge chute that spaces the nib away from a surgical site. When the device is held upright over a surgical site with the nib opened, powder passing the nib is deflected at a first oblique direction with respect to the central axis and into or onto the powder discharge chute, and powder striking the chute is deflected at a rotationally distinct second oblique direction orientation with respect to the central axis and into or onto the surgical site.

1. A biomaterial delivery device comprising an elongated handheld powder storage conduit sized for use in the mouth of a human patient and containing finely-divided powdered sterile biomaterial, the conduit having a proximal end, a distal end, and a bore having a central axis, the proximal end being closed by a movable powder dispensing actuator, the distal end (a) being closed by an openable sealing nib that can be moved from its closed to its open position by force upon the actuator and (b) having a distally-projecting powder discharge chute that spaces the nib away from a surgical site, wherein when the device is held over a surgical site with the proximal end uppermost and the nib actuated to its open position, powder passing the nib is deflected by the device at a first oblique direction with respect to the central axis and into or onto the powder discharge chute, and powder striking the chute is deflected by the device at a rotationally distinct second oblique direction with respect to the central axis and into or onto the surgical site.
