The Needlecatcher comprises a tissue forceps at one end, with a 'piston and barrel' system, which acts as a needle grasper, at the other end of the instrument. It minimizes exposure of the needle during suturing, potentially reducing risk of injury. We evaluate its effect on operator safety during simple wound closure.
Video analysis of 10 clinicians (six junior doctors and four advanced nurse practitioners) closing a standard simulated wound using their normal technique was performed. They were trained in the use of the Needlecatcher, and used it for 10 weeks closing simple wounds in the Emergency Department. Video analysis of wound closure was repeated, using the new instrument. Clinicians filled out a questionnaire for each episode of wound closure, which assessed how they perceived their safety was affected by the device.
Video analysis of clinicians showed that the needle was secured in an instrument and thus unexposed for an average of 60% of the duration of the procedure by standard technique, compared with 95% using the Needlecatcher, with a change of 35% [95% confidence interval (CI): 14-58%, P = 0.005]. Episodes where the needle was grasped by an operator's finger were reduced by 50% (95% CI: 15-85%, P = 0.028). In the questionnaire study of 53 episodes of wound closure, operators perceived their safety to be increased in 38 (71.7%, 95% CI: 66.2-77.2%) episodes, were neutral in 10, and felt their safety was reduced in five.
The Needlecatcher showed the potential to reduce the risk of needlestick injury while suturing.
针夹器的一端是组织镊,另一端是“活塞和筒管”系统,充当针夹。它可使在缝合过程中针始终保持在器械内,从而降低针损伤风险。我们评估了它在简单伤口缝合过程中对术者安全的影响。
对 10 名临床医生(6 名初级医生和 4 名高级护师)使用其惯用技术缝合标准模拟伤口的视频进行分析。他们接受了使用针夹器的培训,并在急诊科使用该器械进行了 10 周的简单伤口缝合。使用新器械再次对伤口闭合进行视频分析。每位临床医生在每次伤口闭合时填写一份问卷,评估他们对器械安全性的看法。
临床医生的视频分析显示,与标准技术相比,使用针夹器时,器械固定针,使其在操作过程的平均 60%时间内不暴露,而使用针夹器时,暴露时间为 95%,差异为 35%[95%置信区间(CI):14-58%,P=0.005]。术者用手指抓针的情况减少了 50%(95%CI:15-85%,P=0.028)。在对 53 次伤口闭合的问卷调查中,有 38 次(71.7%,95%CI:66.2-77.2%)术者认为安全性增加,10 次认为中性,5 次认为安全性降低。
针夹器具有降低缝合时针刺伤风险的潜力。
