University of Pittsburgh researchers have developed an innovative hand-held electrocautery stylus with a protected needle tip. This device enhances surgical safety by automatically shielding the needle tip when not in use, reducing the risk of needle-stick injuries and transmission of blood-borne pathogens. The invention aims to improve existing operating room technology by providing a safer environment for surgeons and medical staff.
Description
The automatically retracting needle-tip electrocautery device features a needle tip that is shielded within a sheath in its resting state. When the actuating buttons for cutting or coagulating current are pressed, the needle tip is exposed either by retracting the sheath or advancing the needle. This mechanism can be achieved mechanically or electromagnetically. Upon releasing the button, the needle is automatically retracted into the sheath, or the sheath advances to conceal the needle tip, ensuring safety.
Applications
• Surgical procedures requiring electrocautery
• Any sharp surgical instrument requiring a hand-switch
• Operating room safety enhancement
Advantages
This invention provides a safer operating room environment by nearly eliminating the risk of inadvertent skin puncture due to exposed electrocautery needles. The automatic shielding mechanism ensures that the needle tip is only exposed during active use, significantly reducing the potential for needle-stick injuries and the transmission of blood-borne pathogens.
Invention Readiness
The invention is currently at the conceptual stage with rough sketches of possible iterations. No prototype has been made yet. The disclosure is being submitted to pursue development through commercial entities.
