The invention relates to a dual-path 3D laparoscope and a dual-path 3D laparoscopic
system, relates to the field of
laparoscopes and laparoscopic systems, and solves the problems that presently, foreign 3D
laparoscopes are high in cost and domestic 3D
laparoscopes do not meet the using standards. The dual-path 3D laparoscope comprises a left light path, a right light path, an upper lighting
fiber, a lower lighting
fiber, and an outer tube; the left light path and the right light path composed of the full-same structures are formed by sequentially arranging a front objective, a middle image transmission rod lens, a rhombic
prism, a rear objective, protective glass and an imaging face in an inner tube. The dual-path 3D laparoscopic
system is composed of the dual-path 3D laparoscope, a dual-path
CCD camera, an image data processor, and a multi-path precision 3D display.
Depth of field of the dual-path 3D laparoscope is 10-180mm, operating length of the outer tube is 330mm, and the
depth of field and the operating length both meet the international general requirement of traditional laparoscope for the smallest length; the dual-path 3D laparoscopic
system is low in cost and convenient to use.
