Automatic smoke removal system of laparoscope

Abstract

The invention belongs to the technical field of automatic smoke removal of laparoscopes and discloses an automatic smoke removal system of a laparoscope. The automatic smoke removal control system ofthe laparoscope comprises an image acquisition module, a smoke detection module, a main control module, an image enhancement module, a three-dimensional model construction module, a locating module, apurification module and a display module. According to the system, the optical locating system in existing surgical operation navigation is fully utilized through the three-dimensional model construction module, other hardware equipment does not need to be introduced, the working flow of existing laparoscopic navigation cannot be influenced, and therefore the system is more economical and direct;meanwhile, a moving path of the tail end of an endoscope head is determined through the locating module according to the known distance and the known angle, and therefore the tail end of the endoscope head can be quickly and accurately moved to a to-be-measured point of a stamp card along the moving path. Moreover, the influences of subjective factors and external factors are eliminated, so thatthe operation difficulty is greatly reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of laparoscopic smoke automatic removal, in particular to a laparoscopic smoke automatic removal system. Background technique [0002] A laparoscope is an instrument with a tiny camera. Laparoscopic surgery is performed using laparoscopes and related instruments: using a cold light source to provide illumination, inserting a laparoscopic lens (3-10 mm in diameter) into the abdominal cavity, and using digital camera technology to make the images captured by the laparoscopic lens pass through the light guide The fiber is conducted to the post-stage signal processing system and displayed on a dedicated monitor in real time. Then the doctor analyzes and judges the patient's condition through the images of different angles of the patient's organs displayed on the monitor screen, and uses special laparoscopic instruments to perform the operation. Laparoscopic surgery mostly uses 2-4 hole operations, one of which...

[0004] The laparoscopic smoke automatic removal system in the prior art has poor smoke removal effect

[0005] The 3D point cloud reconstructed by existing laparoscopes is extremely sparse, and the topological structure information of the object cannot be reconstructed, especially in the case of specular reflection (highlight), due to the existence of light sources on the laparoscope and the smoothness of the organ surface, usually A highlighted area is formed on the surface of the organ, which makes it difficult for the existing 3D point cloud reconstruction scheme to obtain dense point cloud information; at the same time, the surgeon manually adjusts the endoscope by visually measuring the distance from the end of the endoscope lens to the front end of the poking card. The lens can be placed in the front of the poking card. This adjustment method is not only slow, inaccurate, and subjective, but also easily affected by external factors, which increases the difficulty of the operation and reduces the efficiency of the operation; the image acquired by the abdominal camera is distorted. The problem is serious and the deviation is large; the image details are not displayed well
