New puncture resistant materials are being developed for health professional use as protection against disease and needle stick injuries. The needle puncture resistance of protective gloves and glove liners from DePuy DuPont Orthopaedics and of finger guards from Zimmer was evaluated using a computerized needle penetration system to determine maximal penetration forces and the penetration work required for taper point and for cutting edge needles to penetrate these membranes. The Medak portion of the Life Liner glove liner and the Spectra portion of the FingGuard finger guard offered remarkable resistance against needle penetration as compared to the other glove liners and gloves tested. The cutting edge needles required considerably less penetration force and work to penetrate the FingGuard and Life Liner than that required with comparable size taper point needles. Because these unique protective materials had a limited distribution over the hand, the surgeon's hand remained susceptible to inadvertent needle puncture. While this protection against needle penetration in the Life Liner and the FingGuard represents an exciting advance in surgery, it is important to emphasize that this development is only one consideration in the selection of surgical gloves.
正在研发新型抗穿刺材料，供医疗专业人员使用，以预防疾病和针刺伤。使用计算机化针刺系统评估了迪普伊·杜邦骨科公司生产的防护手套和手套衬里以及捷迈公司生产的手指防护套的抗针刺性能，以确定锥形尖端针和切割刃针穿透这些薄膜所需的最大穿透力和穿透功。与测试的其他手套衬里和手套相比，Life Liner手套衬里的Medak部分和FingGuard手指防护套的Spectra部分对针刺具有显著的抵抗力。与尺寸相当的锥形尖端针相比，切割刃针穿透FingGuard和Life Liner所需的穿透力和功要少得多。由于这些独特的防护材料在手部分布有限，外科医生的手仍易被意外针刺。虽然Life Liner和FingGuard的这种抗针刺保护在手术中是一项令人兴奋的进展，但必须强调的是，这一进展只是选择手术手套时需要考虑的一个因素。
