国产可调式自动活检装置在超声导向穿刺中的临床应用

Clinical Application of Adjustable Automated Biopsy Device Made in China in Ultrasoundly Guided Puncture

本文介绍了一种新型组织学活检装置——可调式自动活检装置。它由内槽切割式活检针和活检枪两部分组成。该装置可使活检针的射程在13～23mm范围内连续可调,以适合不同部位和大小的取材需要。临床应用63例,取材总成功率为100％(63/63),首次取材成功率为96.2％(61/63)。说明该装置性能稳定,取材可靠,使用方便,具有推广价值。

This paper introduced a new type of tissue core biopsy appratus-adjustable automated biopsy device(AABD),AABD includes a Tru-Cut needle and a biopsy gun. A mechanism which allows the stroke length of needle to be continuously adjustabled was installed in the AABD, so the stroke length can be easily selected from 13mm to 23mm according to different size and position of lesions or tumors in the body. Biopsy specimens sufficient for histologic analysis are obtained in all of the lesion (63/63).for the first sampling,the success rate was 96.8%(61/63). The result of clinical applications show that AABD is a safe,accurate, sampling-reliable, valuable diagnosis tool.
