A novel back-flush needle integrates endodiathermy, enabling simultaneous blood aspiration and vessel coagulation. This innovative surgical tool enhances procedural efficiency by combining two critical functions.

Area of Science:

  • Surgical instrumentation
  • Minimally invasive surgery
  • Biomedical engineering

Background:

  • Effective hemostasis is crucial in surgical procedures.
  • Current instruments often require multiple tools for aspiration and coagulation.
  • There is a need for integrated devices to streamline surgical workflows.

Purpose of the Study:

  • To develop and present a novel back-flush needle with integrated endodiathermy capabilities.
  • To demonstrate the dual functionality of aspirating blood and coagulating bleeding vessels with a single instrument.

Main Methods:

  • Development of a specialized back-flush needle incorporating electrocautery elements.
  • Integration of aspiration channels within the needle design.
  • Testing of the device's efficacy in aspirating simulated blood and achieving hemostasis on a model vessel.

Main Results:

  • The developed needle successfully aspirated simulated blood.
  • The integrated endodiathermy effectively coagulated a bleeding vessel model.
  • The instrument demonstrated a dual function of aspiration and coagulation.

Conclusions:

  • The novel back-flush needle with built-in endodiathermy offers a promising solution for improved surgical efficiency.
  • This integrated instrument has the potential to reduce operative time and complexity in procedures requiring both aspiration and hemostasis.
