Area of Science:

  • Otolaryngology
  • Surgical Instrumentation
  • Biomedical Engineering

Background:

  • Stapes surgery requires precise manipulation for prosthesis attachment.
  • Current microforceps may lack stability and ease of use during delicate maneuvers.
  • Securing the prosthesis loop to the incus long process is a critical step.

Purpose of the Study:

  • To introduce a novel microforceps designed for stapes surgery.
  • To enhance the stability and ease of crimping prosthesis loops to the incus.
  • To improve surgeon control during the delicate crimping procedure.

Main Methods:

  • Development of a microforceps with an arcuated tip.
  • Incorporation of a retaining spring with a passive opening mechanism.

Related Experiment Videos

  • Testing the tool's efficacy in crimping prosthesis loops to the incus long process.

    • Main Results:

    • The arcuated tip ensures complete spanning of the prosthesis loop around the incus.
    • The retaining spring facilitates a passive opening mechanism, simplifying forceps operation.
    • Surgeons can utilize only forearm flexor muscle tonus for manipulation, enhancing precision.

    Conclusions:

    • The new microforceps provides reliable attachment of prosthesis loops to the incus.
    • The passive opening mechanism minimizes hand movements, reducing tip excursions.
    • The design effectively reduces the risk of incus luxation during stapes surgery.
