| 摘要 |
<p>This invention is an implanter (10) comprising a housing (12), a hollow needle (14) connected to the housing (12), a drive pin (18) positioned within the housing (12); and aligned with the hollow needle (14), a trigger assembly (20) operably connected to both the housing (12), and the drive pin (18). The drive pin (18) has a distal end (22). Further it has a retracted position wherein the distal end (22) of the drive pin (18) is in the housing (12), and an extended position wherein the distal end (22) of the drive pin portion (18) extends out of the housing (12). A pellet (24) is positioned between the needle (14), and the distal end (22) of the drive pin (18) when the drive pin (18) is in the retracted position. The drive pin (18) expels the pellet (24) through the hollow needle (14) when moving from the retracted position to the extended position. The trigger assembly (20) includes a trigger (28) that has a relaxed position and an actuated position. The drive pin (18) moves from the retracted position to the extended position when the trigger (28) moves from the relaxed position to the actuated position. The invention further relates to a method for implanting an object (24) beneath a membrane, comprising the steps of positioning an object (24) to be implanted between a drive pin (18) and a hollow needle (14); positioning a plug (38) between the object (24) and the drive pin (18); inserting the needle (14) through the membrane; and moving the drive pin (18) from a retracted position to an extended position to expel the object (24) through the hollow needle (14), and stop the needle (14) with the plug (38).</p> |
