System zum Einsetzen von Endoprothesen

摘要

The system comprises a tubular bronchoscope having a proximal base (10) and a distal cannula (20), a prosthesis introducing device having a tubular holder (30) for prosthesis (60) insertable into an opening (12) in the base of the bronchoscope and a prosthesis driver (40) insertable into a proximal opening (33) in the base (34) of the prosthesis holder. The prosthesis driver (40) has an axial channel to enable an endoscope (50) to be introduced via an opening (43) in its base (44). In operation (Figs 6-8 not shown), semi-rigid tubular prosthesis (60) is bent longitudinally and introduced into the distal end (31) of the prosthesis holder (30) which is then inserted into the bronchoscope. The prosthesis driver (40) is then inserted into the prosthesis holder until its distal end (41) abuts the proximal end of the prosthesis. An endoscope (50) is then introduced into the axial channel of the driver until the distal end (51) of the endoscope contacts the prosthesis. The prosthesis (60) is ejected by the operator's hand closing handles (35 and 45) attached to the holder and driver respectively.
