1. An insertion device for a surgical access device used to perform a laparoscopic procedure, comprising:
a) a handle assembly including an ergonomic grip section and an elongated barrel section, wherein the barrel section includes a proximal reception port for receiving a laparoscope; and
b) an elongated trocar shaft extending distally from the barrel section and having a tissue-piercing optical tip at a distal end thereof for visualization, the trocar shaft having a first engagement collar positioned at a fixed location on an exterior surface thereof and having a plurality of circumferentially spaced apart stationary engagement fingers for interfingered engagement with complementary circumferentially spaced apart stationary engagement fingers of a second engagement collar that is located within a guide tube of the surgical access device, wherein the engagement fingers of the first engagement collar engage with the engagement fingers of the second engagement collar when the trocar shaft is inserted into the guide tube of the surgical access device, so as to prevent relative radial movement of the trocar shaft and the surgical access device, and wherein the trocar shaft has a central bore communicating with the reception port of the barrel section and extending to the optical tip for accommodating the laparoscope.
