Transrectal prostatic needle biopsy using the bioty gun with needle-protecting sheath / 대한비뇨기과학회지

Biopty gun is an instrument designed for obtaining the prostatic tissue. But there is danger of injury or an examiner`s finger by the sharp needle and risk of unnecessary injury of the rectal mucosa during transrectal approach to the prostate. Therefore we designed the needle-protecting sheath over Biopty gun to eliminate these problems and conduct safe maneuver.
