最近,经直肠的前列腺活检时使用活体组织穿刺针的机会渐多起来。活体组织穿刺针与以往使用的活检针相比具有针细、安全、活检时间短而迅速、减少受检者痛苦的优点。但是,活检针细而柔软,加上针体大而重,检查者手指任意操作常感到困难。 Recently, the chance of using a biopsy needle during transrectal prostate biopsy has increased. Compared with the biopsy needle used in the past, the biopsy needle has the advantages of fine needle, safety, short biopsy time and rapid reduction of the pain of the subject. However, the biopsy needle is thin and soft, and the needle body is large and heavy, and it is often difficult for the examiner’s finger to operate arbitrarily.
