    This study introduces a modified microsurgical clamp with microspikes for secure vas deferens stabilization during vasovasostomy. The innovative design prevents slippage, improving surgical accuracy and potentially reducing incision length.

    Area of Science:

    • Urology
    • Microsurgery
    • Surgical Instrumentation

    Background:

    • Accurate microsurgical vasovasostomy relies on stable vas deferens ends.
    • Commercially available approximating clamps often exhibit slippage, complicating the procedure.
    • Slippage can necessitate extended surgical incisions, increasing patient discomfort and recovery time.

    Purpose of the Study:

    • To develop and evaluate a modified approximating clamp for enhanced vas deferens stabilization.
    • To address the problem of clamp slippage during microsurgical vasovasostomy.
    • To provide a reliable and permanent solution for secure tissue grasping in microsurgery.

    Main Methods:

    • Modification of standard approximating clamps by incorporating stainless steel wire microspikes on the blade tips.

  • Soldering the wire to create short, protruding microspikes designed to grasp only the adventitia of the vas deferens.
  • Application of the modified clamps in microsurgical vasovasostomy procedures.

    • Main Results:

    • The modified clamps demonstrated secure grasping of the vas deferens adventitia without slippage in over 200 anastomoses.
    • The microspike design effectively prevented clamp slippage, ensuring procedural stability.
    • The use of the modified clamp often eliminated the need for inguinal extension of the scrotal incision.

    Conclusions:

    • The microspike approximator offers a permanent and effective solution to clamp slippage in microsurgical vasovasostomy.
    • This clamp modification enhances surgical precision and can potentially simplify the surgical approach.
    • The design is adaptable to various approximating clamp types, offering broad applicability in microsurgical procedures.
