A new disposable needle combines evacuation and cautery for vitrectomy surgeons. This instrument aids in removing preretinal blood and sealing vessels, streamlining surgical procedures.

Area of Science:

  • Ophthalmology
  • Surgical Instrumentation
  • Retinal Surgery

Background:

  • Hemostasis and preretinal blood removal are critical during vitrectomy.
  • Current procedures may require instrument changes for these tasks.

Purpose of the Study:

  • To introduce a novel disposable instrument for simultaneous hemostasis and passive suction in vitrectomy.
  • To enhance surgical efficiency by combining two essential functions into one device.

Main Methods:

  • Development of a disposable evacuation/cautery needle.
  • Utilizing the instrument for clearing vitreous near bleeding sites.
  • Employing the instrument for vessel cauterization during vitrectomy.

Main Results:

Related Experiment Videos

  • The instrument effectively performs both evacuation and cautery functions.
  • Surgeons can manage bleeding and clear vitreous without switching instruments.
  • Potential for improved surgical workflow and reduced operative time.

    • Conclusions:

    • The disposable evacuation/cautery needle offers a dual-function solution for vitrectomy.
    • This innovation can simplify surgical steps and improve efficiency in retinal procedures.
