    Area of Science:

    • Surgical Instrumentation
    • Microdissection Techniques

    Background:

    • Traditional dissection tools may lack precision or versatility.
    • The need for adaptable instruments in delicate surgical procedures is critical.

    Purpose of the Study:

    • To introduce the Keith needle as a dual-purpose instrument for microdissection and blunt dissection.
    • To highlight the design features enabling precise surgical manipulation.

    Main Methods:

    • Utilizing the Keith needle, mounted in a handle, for microdissection tasks.
    • Reversing the needle to employ its eye for blunt dissection.

    Main Results:

    • The Keith needle provides an exceptionally sharp disposable blade for microdissection.
    • The needle's haft can be modified for enhanced control during dissection.
    • The reversed needle eye is effective for blunt dissection procedures.

    Conclusions:

    • The Keith needle is a highly adaptable and precise instrument for both sharp and blunt dissection.
    • Its design facilitates improved surgical outcomes in procedures requiring fine manipulation.
