    • Methods and devices are provided for allowing a surgical instrument to be supported by a surgical support system configured to controllably guide the instrument to a desired position at surgical site. A surgical support system is provided that includes a guide port defining a pivot point about which a surgical instrument advance therethrough can pivot. The guide port, and hence the pivot point, can be located a distance above a tissue surface through which the instrument is advanced. Methods and devices are also provided for allowing insufflation of a body cavity without introduction of an insufflation fluid therein. A mechanical insufflation device is provided that includes an expandable distal member configured to selectively expand and unexpand to mechanically insufflate a body cavity. The mechanical insufflation device can optionally be used with the surgical support system.
    • 提供的方法和装置用于允许外科手术器械由外科支撑系统支撑,所述手术支撑系统构造成可手动地将器械引导到手术部位的期望位置。 提供了一种手术支撑系统,其包括限定枢轴点的引导端口,手术器械可以通过该枢转点枢转。 引导端口以及枢轴点可以位于仪器前进的组织表面上方的距离处。 还提供了用于允许体腔内注射而不在其中引入注射液的方法和装置。 提供了一种机械吹气装置,其包括可膨胀的远端构件,其构造成选择性地膨胀和展开以机械地灌注体腔。 机械吹气装置可以可选地与外科支架系统一起使用。
