Query: Mechanical design of a distal scanner for confocal microlaparoscope: A
  conic solution   This paper presents the mechanical design of a distal scanner to perform a
spiral scan for mosaic-imaging with a confocal microlaparoscope. First, it is
demonstrated with ex vivo experiments that a spiral scan performs better than a
raster scan on soft tissue. Then a mechanical design is developed in order to
perform the spiral scan. The design in this paper is based on a conic structure
with a particular curved surface. The mechanism is simple to implement and to
drive; therefore, it is a low-cost solution. A 5:1 scale prototype is
implemented by rapid prototyping and the requirements are validated by
experiments. The experiments include manual and motor drive of the system. The
manual drive demonstrates the resulting spiral motion by drawing the tip
trajectory with an attached pencil. The motor drive demonstrates the speed
control of the system with an analysis of video thread capturing the trajectory
of a laser beam emitted from the tip.
