    • A tissue protector is adapted to be positioned on the skin surrounding an incision. The tissue protector provides a load bearing surface for surgical tools and instruments to prevent blunt force and pressure trauma to the skin and soft tissues within the incision. In one embodiment, the tissue protector is a sheet of wear-resistant material having an opening corresponding to the incision and expandable as the incision is retracted. In another embodiment, a tissue protector device includes a continuous expandable arrangement of interconnected L-shaped links. In still another embodiment, a one-piece tissue protector includes a flexible panel supported on the skin and a flexible sleeve extending into the incision. Yet another embodiment of the invention resides in a track that is supported about the incision. An instrument support platform is slidably mounted to the track to support a surgical tool relative to the incision.
    • 组织保护器适于定位在切口周围的皮肤上。 组织保护器为外科手术工具和器械提供负载表面,以防止切口内的皮肤和软组织发生钝性和压力创伤。 在一个实施例中,组织保护器是一片耐磨材料,其具有与切口相对应的开口并且随着切口缩回而可扩张。 在另一个实施例中,组织保护装置包括互连的L形链节的连续可展开的布置。 在另一个实施例中,一体式组织保护器包括支撑在皮肤上的柔性面板和延伸到切口中的柔性套管。 本发明的另一个实施例在于围绕切口支撑的轨迹。 仪器支撑平台可滑动地安装到轨道上,以相对于切口支撑手术工具。
