Laparoscopic 3D monitoring equipment with multiple focal depths and multiple spectral segments

Abstract

The invention discloses multi-focal-depth and multi-spectrum-section laparoscope three-dimensional monitoring equipment which comprises a three-dimensional laparoscope with a double-light-path parallel image pickup system, and the three-dimensional display system. The three-dimensional display system comprises a three-dimensional display device and three-dimensional polarization glasses. The three-dimensional laparoscope comprises a laparoscope shell and a double-light-path image pickup system disposed in the laparoscope shell. A multi-spectrum transmitting source and a lens are disposed between the two light paths of the double-light-path image pickup system. Light waves transmitted by the multi-spectrum transmitting source passes the lens to form parallel light, and the parallel light is combined with the double-light-path image pickup system to form the double-light-path parallel image pickup system. A light transmitting bundle socket is further disposed inside the laparoscope shell and used for being connected with an external image collecting and processing system to alternately display the left-eye surgery images and the right-eye surgery images, picked up by the double-light-path parallel image pickup system, in the three-dimensional display device.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a laparoscopic three-dimensional monitoring device with multiple focal depths and multiple spectral segments. Background technique [0002] Currently, the in vivo observation instrument used in the medical field is usually a two-dimensional laparoscope. This two-dimensional laparoscope is a single-lens laparoscope that can be inserted into the body through the organ tube. This single-lens laparoscope is composed of a puncture tube, an optical fiber puncture rod arranged in it, and a camera lens installed at the insertion end of the optical fiber. After the optical fiber puncture rod is connected to the corresponding monitor, the picture taken by the camera when the optical fiber puncture rod is inserted can be observed through the monitor. The main problem of this single-lens laparoscope is that the projected picture has no sense of distance and cannot see the three-dimensional d...

AI Technical Summary

Problems solved by technology

The main problem of this kind of single-lens laparoscopy is that the projected picture has no sense of distance, and the three-dimensional depth cannot be seen, which brings great difficulties to the operation.

Doctors need to use a lot of experience to infer the three-dimensional relationship between the adjacent structure of blood vessels in the lesion and the direction of the tissue. This will not only prolong the operation time, but also easily injure healthy tissues by accident, bringing serious safety hazards and increasing the chance of complications and mortality
