System and method for performing surgical procedures with a modular surgical system

A surgical system comprising:

• a reusable handle assembly having a controller and an electrical switch;
• a reusable cannula assembly steerable by the reusable handle assembly, the reusable cannula assembly being a tubular member defining a lumen therethrough, the reusable cannula assembly having first linkages and second linkages formed on sections of the tubular member;
• and
• a plurality of surgical instruments configured to be inserted through the reusable handle assembly and configured to advance through the reusable cannula assembly from a proximal end to a distal end thereof such that the plurality of surgical instruments are engaged with at least one trigger mechanism of the reusable handle assembly;
• wherein the reusable handle assembly, the reusable cannula assembly, and the plurality of surgical instruments are modular components configured to be releasably coupled to each other;
• and
• wherein the first linkages have a first linear configuration and a second pre-set bent configuration, the first linkages configured to transition from the linear configuration to the pre-set bent configuration in response to activation of the electrical switch of the reusable handle, the second linkages articulating in response to the controller.
