Since the original spring clip sterilization studies were reported, a number of clinically important modifications to the spring clip and applicator have been developed. The spring-loaded clip, manufactured by Richard Wolf Medical Instruments Corporation of Chicago, Illinois, and Rocket of London, Inc., London, England, and New York, New York can be applied with either a one- or two-incision applicator and the clips and applicators currently available incorporate improvements to the original prototypes in design, manufacture, and quality control. The two-incision applicator is associated with significantly fewer misapplications and the high pregnancy rates reported with the original clip and applicator have not occurred with the current designs. Comparative studies between the clip and band have revealed less operative bleeding and pain associated with the clip. The method is appropriate to all women requesting sterilization but especially to those in the younger age group who may subsequently request reversal because of divorce and remarriage.
自从最初的弹簧夹绝育研究报告发表以来，对弹簧夹和施夹器进行了一些具有临床重要意义的改进。由伊利诺伊州芝加哥的理查德·沃尔夫医疗器械公司、英国伦敦的伦敦火箭公司以及纽约的该公司生产的弹簧夹，可以使用单切口或双切口施夹器进行放置，并且目前可用的夹子和施夹器在设计、制造和质量控制方面对原始原型进行了改进。双切口施夹器的误操作明显减少，而且目前的设计并未出现原始夹子和施夹器所报告的高妊娠率。夹子和套扎带的对比研究表明，夹子相关的术中出血和疼痛较少。该方法适用于所有要求绝育的女性，尤其适用于那些因离婚和再婚可能随后要求复通的年轻女性群体。
