Covidien E2450H Edge Button Switch Pencil Blade Electrode, Holster 10' BX/50

• Model: E2450H
• Overall Length: 8 inches

The E2450H Edge Button Switch Pencil with Blade Electrode is designed for monopolar electrosurgery, which is a very common mode of surgical cutting and coagulation. The surgeon holds this handpiece, which delivers high-frequency current from the generator to the tissue via the blade electrode. By pressing the button switch, the current is activated (cut or coagulation modes depending on generator settings), allowing precise incisions or hemostasis. The hex-lock mechanism ensures the electrode shaft stays firmly in place and prevents rotation during use, enhancing stability and control during delicate maneuvers.

One of the key features is the EDGE coating on the blade or needle electrode. This coating aims to reduce sticking (i.e. tissue adhering to the electrode), reduce carbon deposits, and maintain cutting efficiency across a range of tissue types. In effect, the surgeon can expect more consistent performance and possibly fewer interruptions for cleaning the electrode tip during the procedure. The fact that it accepts standard 3/32" diameter shafts means that users have flexibility in electrode selection for different cutting or coagulation needs.

In operating room workflows, this kind of pencil is a standard staple of electrosurgical setups. It’s lightweight, ergonomic, and provides a direct interface between surgeon and energy source. Because it is disposable and sterile, there’s no need for reprocessing, which reduces risk of cross-contamination and instrument maintenance overhead. The included holster gives a place to rest the pencil safely when not in use. As with all monopolar pencils, safe usage requires proper return electrode / patient grounding, vigilance about inadvertent current paths, and operator awareness of insulation integrity.
