Three-dimensional electronic gastroscope system and using method thereof

Abstract

The invention belongs to medical appliances and particularly relates to a three-dimensional electronic gastroscope system. The three-dimensional electronic gastroscope system comprises a soft electronic gastroscope and a processing host, a light source host and a work station component which are connected with the soft electronic gastroscope, wherein the soft electronic gastroscope comprises a soft working end part; the soft working end part is provided with a multi-charge coupled device (CCD) array module which performs three-dimensional stereoscanning shooting, displays panoramic three-dimensional stereopictures, and performs stereoscopic image reconstruction on gastral cavities; and the multi-CCD array module comprises at least one first CCD array which is arranged on the front end surface of the tip part of the soft working end part and at least one second CCD array which is arranged on the excircle surface of the tip part of the soft working end part. By the three-dimensional electronic gastroscope system, annular and linear image shooting is performed on the gastral cavities, acquired data are comprehensively processed by the processing host to acquire three-dimensional images of the gastral cavities, and the stereoscopic images of the gastral cavities have a practical significance for doctors to observe lesions in the gastral cavities and research the environments of the gastral cavities at multiple angles and formulate the most reasonable and effective treatment scheme.

Description

Technical field [0001] The invention belongs to a medical appliance, and in particular relates to a three-dimensional electronic gastroscope system that uses a multi-CCD array to reconstruct three-dimensional images. Background technique [0002] CCD (Charge-Coupled Device) is an important part that can be used in stereo cameras. It is a photosensitive semiconductor device on which the photosensitive unit converts the received light into a charge, and the charge is proportional to the intensity of the incident light. The technology of the CCD image sensor is extremely mature and can be spliced ​​into an array of any shape as required. In 1999, Fuji Company introduced super CCD technology. With the same area and number of photosensitive cells as ordinary CCD, its resolution increased by 60%, dynamic range increased by 130%, color reproduction ability increased by 40%, and energy consumption decreased by 40%. Improved the function of CCD. The size of the photosensitive cell of C...

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 gastroscope. Therefore, in order to obtain a clear three-dimensional image in the gastric cavity, it is imminent to design an endoscopic technology that combines multi-CCD array technology with gastroscope.
