Originally developed at the request of a neurosurgeon, today’s Colorado needle line now includes more than 40 configurations tailored to the unique needs of diverse procedures. The needles are compatible with a range of monopolar diathermy handpieces on the market, including Stryker's neptune E-SEP smoke evacuation pencil. With an ultra-sharp tip and unparalleled small size, Colorado needle tips provide the consistent precision and patient protection you want from your everyday, "go-to" surgical instruments.
