Objective: To evaluate the diagnostic accuracy and complication of spring core biopsy needle under ct guidance for percutaneous pulmonary biopsy.
目的：探讨CT引导下使用弹簧芯状活检针行经皮肺穿刺活检的诊断准确性和并发症发生率。
Methods: 38 cases of percutaneous pulmonary biopsy were performed using spring core biopsy needle under CT guidance.
方法：38例使用弹簧芯状活检针的经皮肺穿刺活检。
The piston rod self-locking type gas spring end there is a needle valve open the needle valve is self-locking type gas spring can run as the free type gas spring;
自锁型气弹簧是一种可以在行程任一位置锁定的气弹簧。 在自锁型气弹簧的活塞杆端部有一个针阀打开这个针阀，则自锁型气弹簧可以象自由型气弹簧那样运行；
The system of measurement is composed by joint, spring pipe, and power transmission setting, and use the needle to note the number.
仪表的测量系统由接头、弹簧管和传动机构组成。通过指针指示仪表读数。
The needle sheath may be manually actuated or may be actuated by decompression of a spring.
所述针头鞘可以手动致动或者可以通过弹簧的解压缩致动。
The results show that stiffness of spring does not affect the injection rate, but the mass of will affect the needle valve closing response time.
结果表明，电磁阀铁心弹簧刚度对喷油规律没有影响，但其质量影响针阀落座响应时间；
