Wireless capsule endoscope with annular lens

Abstract

The invention discloses a wireless capsule endoscope with an annular lens, which comprises a capsule casing (1), a control device (2), a shooting device (3), a light source (4), a wireless receiving / transmitting device (5) for the wireless transmission of a shot image and an energy source supplying device (6) for respectively providing an energy source to the control device (2), the shooting device (3), the light source (4) and the wireless receiving / transmitting device (5), wherein the control device (2), the shooting device (3), the light source (4), the wireless receiving / transmitting device (5) and the energy source supplying device (6) are all sealed in the capsule casing (1). The wireless capsule endoscope with the annular lens is characterized in that a transparent area (11) for the light source (4) to project out light rays is arranged on the capsule casing (1), the shooting device (3) comprises an image sensor (31), a reflecting mirror (32) is arranged between the image sensor (31) and the transparent area (11), the outer side of the reflecting mirror (32) is sleeved with an annular lens (33), and light rays at the outer side of the transparent area (11) are reflected onto the image sensor (31) for imaging by the annular lens (33). According to the endoscope, the image sensor is effectively utilized by combining the annular lens and the reflecting mirror. A photo shot by utilizing the system disclosed by the invention does not have a central black area, and the effective information quantity of a picture is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of clinical medical auxiliary equipment, and relates to a wireless capsule endoscope system with an annular lens. Background technique [0002] The history of humans using endoscopes to detect internal organs can be traced back to the 19th century. In 1806, German scientist Philipp Bozzini first invented the prototype of an endoscope that used candlelight to detect the human bladder and intestines. Since then, different types of endoscopes (such as gastroscopes for detecting gastric lesions and colonoscopes for detecting intestinal lesions) have been continuously developed and improved, which has greatly helped doctors perform digestive system tests on patients. disease detection. [0003] In the past ten years, endoscope-related science and technology have developed rapidly, especially the birth of a medical auxiliary device that can be used to supplement and improve gastroscope and colonoscope—wireless c...
