DTR MEDICAL CERVICAL ROTATING BIOPSY PUNCH
The single-use DTR Medical Cervical Rotating Biopsy Punch from Innovia Medical (Swansea, United Kingdom) “works great” and “is reasonably cost-effective to replace reusables.”
Background. Integral to every colposcopic examination is the potential need to biopsy abnormal appearing tissues. To accomplish this latter task, numerous punch-style biopsy devices have been developed in a variety of jaw shapes and styles, crafted from materials ranging from stainless steel to titanium to ceramic, with the ultimate goal the same—get a piece of tissue from the cervix as easily as possible.
Design/Functionality. DTR Medical Cervical Rotating Biopsy Punch is a single-use sterile device that comes packaged as 10 per box. It features Kevorkian-style “stronger than Titanium” jaws that yield a 3.0 mm x 7.5 mm sample attached to a metal shaft that can rotate 360°. The shaft inserts into a lightweight plastic pistol-grip style handle. From tip to handle, the device measures 36.5 cm (14.125 in).
In my experience with its use, the DTR Medical Cervical Rotating Biopsy Punch performed flawlessly. Its relatively low-profile jaws allowed for unobstructed access to biopsy sites and the ability to rotate the jaws was a big plus. The “stronger than Titanium” jaws consistently yielded the exact biopsies I wanted, like a knife going through butter.
Innovation. From an innovation standpoint, the DTR Medical Cervical Rotating Biopsy Punch is more of an engineering “duh” than “wow,” but it works great so who cares that it’s not a fusion reactor. That said, the innovative part from Innovia Medical is their ability to make such a high-quality biopsy device and sell it at a price that makes it reasonably cost-effective to replace reusables.
Summary. Whether it is a Tischler, Kevorkian, or Burke tip, the real question before any gynecologist uses the cervical biopsy device she/he/they has in her/his/ their hand is, will it cut? Because all reusable surgical instruments are in fact reusable, those edges that are designed to cut invariably become dull with reuse. And, unless they are meticulously maintained and routinely sharpened (spoiler alert, they never are), providers are not infrequently chagrinned by the gnawing rather than cutting that these instruments deliver. Thinking back, I could not remember the last time I had made an incision with a surgical scalpel blade that had previously been used then sharpened and re-sterilized. Then I did remember…never. Reflecting on this, I wondered why I was doing this with my cervical biopsy devices. While I really do not like the environmental waste created by single-use devices, reusable instruments that require re-processing do have an environmental impact and a significant cost. Considering this, I do not think that environmental reasons are enough of a barrier to justify using dull biopsy tools if it can be done cost-effectively with a minimal carbon footprint. All-in-all, I like this product, and I plan to use it. ●
