Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Surgical Instrumentation

Background:

  • Meniscectomy procedures are common in orthopedic surgery.
  • Current arthroscopic punches have limitations in reachability and handle ergonomics.
  • Existing instruments may pose risks of damaging healthy tissue during meniscal resection.

Purpose of the Study:

  • To develop and evaluate an improved arthroscopic punch with a side-ways steerable tip.
  • To design an ergonomic handle for enhanced instrument control and user comfort.
  • To assess the safety and efficiency of the novel instrument in meniscectomy.

Main Methods:

  • Analysis of existing meniscectomy procedures to identify areas for improvement.
  • Design of a novel punch with a side-ways steerable tip and an ergonomic handle.

Related Experiment Videos

  • Comparative experiments using a knee joint model with objective and subjective assessments.
  • Evaluation of task times and risk of damage to healthy tissue.

    • Main Results:

    • The steerable punch concept demonstrated promising results in improving meniscal tissue reachability.
    • Faster task times were achieved compared to conventional instruments without increasing the risk of collateral tissue damage.
    • The ergonomic handle design provided intuitive control and improved user comfort.

    Conclusions:

    • A side-ways steerable arthroscopic punch offers a safer and more efficient approach to meniscectomy.
    • The developed ergonomic handle enhances usability and control during arthroscopic procedures.
    • Further development is recommended to optimize the instrument tip and force transmission for clinical application.
