    Area of Science:

    • Neurosurgery
    • Medical Devices
    • Biomedical Engineering

    Background:

    • Aneurysm surgery requires precise and secure clip application.
    • Existing surgical clips may face limitations in stability, blade length, and placement versatility.
    • The development of improved surgical clips is crucial for patient safety and surgical outcomes.

    Purpose of the Study:

    • To introduce and describe a novel surgical clip designed for aneurysm surgery.
    • To highlight the design features that enhance the clip's performance and usability.
    • To present the material and mechanical properties of the new aneurysm clip.

    Main Methods:

    • The surgical clip is constructed from 2 mm diameter stainless-steel wire.
    • Key design features include a stabilizing wire, a stronger coil spring, and notched grasping sites.
    • The clip is compatible with both rigid and rotating clip appliers.

    Main Results:

    • The stabilizing wire prevents blade scissoring, enhancing stability.
    • A stronger coil spring allows for longer blades and reduces slippage, with opening pressures of approximately 175 g (standard) and 320 g (strong).
    • Notched grasping sites facilitate precise positioning using rotating clip appliers, improving optimal placement.

    Conclusions:

    • The novel aneurysm surgical clip offers improved stability, reduced slippage, and enhanced placement precision.
    • The design advancements, including the larger diameter wire and stronger spring, contribute to superior performance in aneurysm surgery.
    • This clip represents a significant improvement for neurosurgical interventions requiring secure and accurate aneurysm clipping.
