Sheath Type Scalpel vs. PenBlade™ Transcript

In this video I’m going to talk about the standard Sheath Type scalpel. How it is activated and retracted, the weight, the stability and any special features.
I am going to compare it to the PenBlade.
This standard Sheath Type scalpel requires that the user retract a sheath that covers the blade using the thumb. When the user then wants to cut in either in a pen-like position or a palm grip position you will notice that the fingers cover the protective sheath. So when it is time to retract to the sheath, to make it safe, the user has to reposition the hands.
Again I will illustrate this by showing that, when I go into a pen-like cutting position, with the sheath type scalpel, my fingers cover the safety feature and I have to reposition the hand to retract the sheath. This often discourages users from making this safe.
Contrast that with the PenBlade. The PenBlade is intuitively activated. When the user repositions the hands, the user is able to retract the blade in the pen-like grip position. Or, if the user prefers the palm grip position, for other cutting techniques, you will still notice the users fingers are very close to the retraction button, which makes he or she more likely to retract the PenBlade and make it safe.
Another feature I want to illustrate is the rigidity of the sheath type scalpel. You will notice there is quite a bit of flex. When the user is cutting you will notice there is quite a bit of play in the scalpel, which makes these devices less desirable in the operating room.
Contrast that with the PenBlade, you will notice its ergonomic design enhances rigidity. When the user has the blade activated there is very little flex or play in the PenBlade, especially in the blade tip, which is only from the flexibility that is seen from the actual metal of the blade.
Finally, I am going to talk about the patented suture trimming groove, a feature not available in other safety scalpels. This feature reduces the cost of instrumentation by eliminating sterile suture trimming scissors and also encourage safety in scalpel use, by the provider, because the blade is in the retracted and safe position when trimming the suture lengths.
Here is an example with a central venous catheter. Imagine if the catheter was placed in the patient’s neck, in the jugular vein, and I am trimming this suture. If I use a traditional scalpel I have to expose the blade. If I use any of the available safety scalpels I have to expose the blade. Using the patented PenBlade suture trimming Groove I don’t have to expose the blade. I simply articulate the suture lengths with the blade, via the groove, and safely trim the suture.
