Three-dimensional electronic duodenoscope system and use method thereof

Abstract

The invention belongs to medical instruments, and relates to a three-dimensional electronic duodenoscope system for reconstructing a three-dimensional image by using a multi-CCD (Charge Coupled Device) array, which comprises a soft electronic duodenoscope. The soft electronic duodenoscope comprises a soft working end part, wherein the soft working end part is provided with a multi-CCD 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 duodenum, 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. Image information in the duodenum is obtained, the data is transmitted to a processing host computer for centrally processing and reconstructing so that thethree-dimensional environment in the duodenum is reproduced, and the three-dimensional image in the duodenum has valuable significance on formulating the most reasonable effective processing scheme for doctors to observe internal pathological changes of the duodenum in multi-angle manner and research the environment of the duodenum.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a three-dimensional electronic duodenoscope system which utilizes multi-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%. Improve the function of CCD....

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 duodenoscope. Therefore, in order to obtain a clear three-dimensional image in the duodenum cavity, a multi-CCD array technology and duodenoscope are designed. Endoscopic technology combined with colonoscopy is imminent
