TRANSBRONCHIAL NEEDLE ASPIRATION DEVICE |
摘要 |
<p>Transbronchial needle aspiration (TBNA) device. In one embodiment, the device comprises a handle and a flexible catheter, the handle having a bore, the proximal end of the catheter being fixed within the handle bore. A protective tubular hub having a flared distal end is press-fit coaxially within the distal end of the catheter, the distal end of the catheter being sealed around the distal end of the hub so as to define a distal opening. A hollow needle having a sharp tip at its distal end is disposed within the catheter, the needle tip being sized for insertion through the distal opening of the catheter. The distal end of a flexible wire is coupled to the proximal end of the needle, the proximal end of the wire extending through the handle bore and coupled to a button slide accessible through a slot in the handle. The button slide is movable between a distal position in which the needle tip extends through the distal opening of the catheter and a proximal position in which the needle tip is disposed within the hub. When in either its distal position or its proximal position, a pawl on the button slide releasably engages a corresponding notch on the handle to lock the button slide in place.</p> |
