求翻译：【摘要】 目的 对穿刺针清洗方法的改进后的评价，提高穿刺针的清洗效果。方法 选取临床使用后的活检穿刺针200套，随机分为A组、B组。每组样本量100套，其中A组采用手工清洗，B组采用手工清洗加全自动喷淋式清洗机清洗。2组样本经上述方法洗涤后，每套穿刺针采用目测和借助带光源放大镜检查的方法，同时每组随机抽取30套穿刺针，采用蛋白质残留法监测清洗效果。结果 B组的清洗方法对穿刺针的清洗效果高于A组，A、B两组目测和放大镜方法检查合格率分别为： 85％、98%, （X2=10.865，P0.05）两组无统计学差异（普通器械X2=2.67，P>0.05， 管腔器械X2=3.33，P>0.05）。结论 穿刺针的清洗质量与清洗方法密切相关，采用人工清洗加全自动清洗机的清洗后的穿刺针，清洗效果较好，可有效保证穿刺针的清洗质量，保证病人的安全，并利于穿刺针的保养和重复利用，节约医疗资源。是什么意思？

The "Summary" objective evaluation on the improvement of puncture needle cleaning methods, improve the cleaning effect of needle. Biopsy needle after the clinical use of methods to select 200 sets, randomly divided into groups a, b groups. Sample size per group of 100, where a group of manual cleaning, group b manual cleaning and automatic spray cleaning machine clean. 2 sets of samples by applying the above after washing, each needle used visually through with light sources and methods of the magnifying glass to check, while each group randomly 30 sets of needle, with protein residue monitoring cleaning effect. Results Group b cleaning methods on puncture needle cleaning effect than a group of, visually and magnifying glass method checks a and b group rate are: 85%, 98%, (X2=10.865,P <0.01），a、b两组蛋白质残留法监测清洗合格率分别为：83.3％、96.7%, （x2="1.667，P"> 0.05) no statistically significant differences between the two groups (common instrument X2=2.67,P>0.05, X2=3.33,P>0.05 lumen devices). Conclusion cleaning quality and cleaning method for puncture needle are closely related, with manual cleaning and automatic cleaning machine cleaning needle, good cleaning effect, effectively guarantee the quality of needle cleaning, keep patients safe and conducive to the maintenance of needle and repeated use, save medical resources. </0.01），a、b两组蛋白质残留法监测清洗合格率分别为：83.3％、96.7%,>
