Robotic surgical system with control drive assembly for single port surgical technology

A robotic surgical system includes an instrument cart having a mounting arm assembly and a control drive assembly coupled to the mounting arm assembly. The control drive assembly includes a frame assembly, a first drive unit and a second drive unit mounted to the frame assembly, and a lead screw assembly. Each drive unit is positioned to translate relative to the gantry assembly between a retracted position and an advanced position. The first drive unit is coupled to a first surgical instrument and the second drive unit is coupled to a second surgical instrument. The lead screw assembly is mounted to the frame assembly and includes a first lead screw operatively associated with the first drive unit and a second lead screw operatively associated with the second drive unit. The first lead screw rotates to cause the first drive unit to translate relative to the rack assembly. The second lead screw rotates to cause the second drive unit to translate relative to the rack assembly. 一种机器人手术系统包括具有安设臂组件的器械推车以及联接至该安设臂组
