An imaging device for in vivo medical applications that enables minimally invasive surgical procedures. The imaging device includes an elongated frame having a base, a module housing, and a helical member interposed between the base and module housing. The imaging device further includes an actuation unit positioned within the frame that engages the module housing causing the frame to bend at the helical member. The module housing includes an imaging module and may include other modules including tools used for laparoscopic surgery.
