    • A retractor system for percutaneous surgery in a patient includes first and second retractor portions positionable opposite one another in an incision of the patient. The system also includes at least one actuating member operable to provide an oscillating motion to at least one of the first and second retractor portions. The actuating member is in communication with a controller and is responsive to the controller to move and adjust at least one of the first and second retractor portions between a first position and a second position. The system also includes at least one pressure sensor and display and at least one timing circuit with display. In another form, a method is directed to retracting tissue for percutaneous access to a surgical site in a patient using the pressure sensors and display as will as the timing circuit and display to assure that the amount of pressure applied and the duration does not exceed pre-determined values.
    • 用于患者经皮手术的牵开器系统包括可在患者切口中彼此相对定位的第一和第二牵开器部分。 该系统还包括至少一个致动构件,其可操作以向第一牵拉器部分和第二牵拉器部分中的至少一个提供摆动运动。 致动构件与控制器连通并且响应于控制器在第一位置和第二位置之间移动和调节第一牵拉器部分和第二牵拉器部分中的至少一个。 该系统还包括至少一个压力传感器和显示器以及至少一个具有显示器的定时电路。 在另一种形式中,一种方法涉及使用压力传感器缩回用于经皮进入患者手术部位的组织,并且如同计时电路和显示器那样显示,以确保施加的压力量和持续时间不超过预先设定的时间 - 确定的值。
