Evaluation of automatic disposable rotating cartridge skin staplers.
Burn surgeons commonly employ skin staples for the application of skin grafts and to secure dressings on donor site dressings and over skin grafts. Disposable skin staplers with rotating cartridges are ideally suited for wound closure because the position of their cartridges can be manually adjusted to facilitate placement of their staples. In response to the burgeoning interest in disposable automatic skin staplers with rotating cartridges, three different models are now commercially available. This report describes the design configuration and mechanical performance of these disposable automatic staplers and their staples. Mechanical performance of these staplers and staples has been assessed by standardized tests that can be replicated in any research laboratory. On the basis of these objective design and performance parameters, the Premium stapler is recommended for wound closure. This stapler provides maximal visualization of the wound as well as the staple during its formation. It delivers the staple into the skin or wound in a manner that the cross member of the staple is above the skin or wound surface. In addition, the Premium stapler has a prepositioning mechanism that can be controlled by the surgeon with minimal force. This mechanism allows the stapler to hold its staple securely, even when its pointed legs extend beyond the delivery end of the stapler. Force required to form its staples is so low that the surgeon can staple repetitively without fatigue. Finally, the Premium stapler delivers a staple that has a uniform geometry and sharp points that can easily penetrate tissue.
