Block Needle (Verschlussnadel): Pr\u00e4zise Gef\u00e4\u00dfverschl\u00fcsse f\u00fcr minimal-invasive Eingriffe<\/p>\n

Klinischer Zweck<\/h2>\n

Die Block Needle wurde f\u00fcr eine zuverl\u00e4ssige Gef\u00e4\u00dfversiegelung und gezielte Gewebeokklusion entwickelt und erm\u00f6glicht einen kontrollierten Verschluss bei interventioneller Radiologie, Biopsietraktversiegelung und Embolisationstherapien. Sie erm\u00f6glicht es \u00c4rzten, Blutgef\u00e4\u00dfe oder G\u00e4nge (z. B. Gallenwege, Eileiter) schnell zu isolieren und gleichzeitig kollaterale Gewebesch\u00e4den zu minimieren.<\/p>\n

Kritische Vorteile<\/h2>\n

Dual-Mode-Okklusion<\/strong>
\n- Scharfe Spitze zum Eindringen: Ultra-abgeschr\u00e4gte 15\u00b0-Spitze f\u00fcr sanftes Eindringen in das Gewebe.
\n- Blunt-Tip-Expansion: Einsetzbarer Mikropfropfen schafft sofortige 3D-Okklusion.
\nErh\u00f6hte Sicherheit<\/strong>
\n- Tiefenspezifische r\u00f6ntgendichte Marker (alle 5 mm) unter Durchleuchtung.
\n- Die Drehmoment-Kontrollnabe verhindert ein versehentliches \u00dcberschie\u00dfen.
\nEffiziente Verfahren<\/strong>
\n- 30% schnellere Gef\u00e4\u00dfabdichtung im Vergleich zur manuellen Kompression.
\n- Luer-Lock-Kompatibilit\u00e4t f\u00fcr die gleichzeitige Verabreichung von Emboliemitteln.<\/p>\n

Fortgeschrittene Werkstofftechnik<\/h2>\n

- Kern: Medizinisch 304L<\/a> Edelstahl (Au\u00dfentoleranz: \u00b10,02 mm).
\n- Oberfl\u00e4che: Hydrophile Polymerbeschichtung (Kontaktwinkel: 18\u00b0) reduziert die Reibung um 40%.
\n- Sichtbarkeit: Distale Wolframspitze (20%-Dichte) f\u00fcr CT\/MRI-Kompatibilit\u00e4t + lasergravierte echogene B\u00e4nder f\u00fcr Ultraschallf\u00fchrung.<\/p>\n

Anwendungen<\/h2>\n

- Verschluss von Biopsiekan\u00e4len (Leber\/Niere)
\n- Blockierung der Gef\u00e4\u00dfe vor der Embolisation
\n- Kontrolle mikrovaskul\u00e4rer Leckagen in der rekonstruktiven Chirurgie
\n- Nicht-chirurgische Sterilisationsverfahren<\/p>\n

Konformit\u00e4t & Anpassung<\/h2>\n

- Steriles EO gamma-verpackt | ISO 13485 | FDA 21 CFR 880.5570
\n- Feinheitsbereich: 18G-25G | L\u00e4ngen: 5cm-20cm
\n- OEM-Optionen: Spulenverst\u00e4rkte Sch\u00e4fte | Antibakterielle Beschichtungen<\/p>","protected":false},"excerpt":{"rendered":"
