Three-dimensional electronic bronchoscope system and use method thereof

Abstract

The invention belongs to the medical instruments, and in particular relates to a three-dimensional electronic bronchoscope system, which comprises a soft electronic bronchoscope, and a processing host computer, a light source host computer and a working station assembly that are connected with the soft electronic bronchoscope, wherein the soft electronic bronchoscope comprises a soft working end part which is provided with a multi-CCD (Charge Coupled Device) array module used for three-dimensionally scanning and shooting and displaying a full-view three-dimensional image and reconstructing a three-dimensional image of the gastral cavity, and the multi-CCD array module comprises at least one first CCD array arranged at the front end face of the first end part of the soft working end part and at least one second CCD array arranged on the surface of the excircle of the first end part of the soft working end part. In the invention, image information in the bronchus is obtained, data is transmitted to the processing host computer for centrally processing and reconstructing so that the three-dimensional environment in the bronchus is reproduced, and the three-dimensional image of the bronchus has valuable significance on formulating the most reasonable and effective processing scheme for the doctors to observe the internal pathological changes of the bronchus in a multi-angle manner and researching the environment of the bronchus.

Description

technical field [0001] The invention belongs to medical equipment, and in particular relates to a three-dimensional electronic bronchoscope system which utilizes multiple CCD arrays to reconstruct stereoscopic images. Background technique [0002] A CCD (Charge-Coupled Device, Charge-Coupled Device) is an important component that can be used in a stereo camera. It is a photosensitive semiconductor device on which the photosensitive unit converts the received light into electric charge, and the electric charge is proportional to the intensity of incident light. The technology of CCD image sensor is extremely mature, and it can be spliced ​​into arrays of any shape as required. In 1999, Fuji launched the super CCD technology. Under the same area and number of photosensitive units as the ordinary CCD, its resolution increased by 60%, the dynamic range increased by 130%, the color reproduction ability increased by 40%, and the energy consumption decreased by 40%.

Problems solved by technology

[0004] Some stereoscopic endoscopes use a binocular structure, and the front end of the endoscope can be one lens or two lenses. The image of the object is output through the two eyepieces. The doctor can observe through the binoculars similar to the human eye. The three-dimensional image of the object can also be connected to a special processing host and the display, and the three-dimensional image can be displayed on the display through the processing of the processing host, but this image is also a single angle, which has certain limitations

Although the binocular stereoscopic endoscope can obtain the stereoscopic feeling similar to the human eye observing objects, but due to the limitation of the human body cavity, it cannot stereoscopically reflect the stereoscopic picture of the entire operation area, so doctors are using the current endoscope for surgery. At the same time, it must be restricted by vision, which has certain restrictions on the development of surgery and the improvement of the cure rate of the disease.

[0005] In the prior art, the concept of CCD array has not been combined with bronchoscope. Therefore, in order to obtain a clear three-dimensional image in the bronchial cavity, it is imminent to design an endoscopic technology that combines multi-CCD array technology with bronchoscope.
