Capsule endoscopy capable of measuring temperature

Abstract

The invention relates to a capsule endoscopy capable of measuring temperature. The capsule endoscopy comprises a main body cavity, and a visual hemispherical shell cavity and a temperature-sensitive measuring hemispherical shell cavity which are connected with two ends of the main body cavity, wherein the visual hemispherical shell cavity is defined by a transparent hemispherical shell, and an illumination light source probe is arranged at the center of a sphere; the temperature-sensitive measurement hemispherical shell cavity is surrounded by a hemispherical shell deposited with a temperature-sensitive quantum dot film, and a temperature-sensitive quantum dot exciting light probe is arranged at the center of the sphere; a visual imaging assembly, a photoelectric conversion assembly, a signal wireless transmission assembly, an emitted light acquisition part and the like are arranged in the main body cavity, and visual detection in the digestive tract is realized through the visual imaging assembly and the illumination light source probe; the real-time temperature information of a wound part in the digestive tract is acquired through an emitted light acquisition part, the temperature-sensitive quantum dot exciting light probe and a temperature-sensitive quantum dot film spherical shell; and a visual imaging signal and a temperature-sensitive photoelectric signal are wirelessly transmitted through a signal wireless transmission assembly. According to the invention, integration of digestive tract visual imaging detection and digestive tract temperature measurement functions is realized.

Description

technical field [0001] The invention belongs to the technical field of digestive tract capsule endoscope, in particular to a temperature-measurable capsule endoscope. Background technique [0002] Capsule endoscopy has been widely cited in medical diagnosis, such as the Chinese patent "Medical Magnetic Capsule Endoscope" with the publication number CN20120378138.6, which uses an external magnetic field excitation and a magnetic field sensor chip in the capsule endoscope The interaction among them realizes the flexible control of the movement of the capsule endoscope inside the digestive tract, and then realizes the rotation of the three-dimensional angle in the body for visualization and imaging; Acquisition and collection of temperature information. The Chinese patent with the publication number CN110037746A "Capsule-type digestive tract liquid collection device controlled by external magnetic field and its capsule body" provides a capsule-type digestive tract liquid colle...

[0002] Capsule endoscopy has been widely cited in medical diagnosis, such as the Chinese patent "Medical Magnetic Capsule Endoscope" with the publication number CN20120378138.6, which uses an external magnetic field excitation and a magnetic field sensor chip in the capsule endoscope The interaction among them realizes the flexible control of the movement of the capsule endoscope inside the digestive tract, and then realizes the rotation of the three-dimensional angle in the body for visualization and imaging; Acquisition and collection of temperature information

The Chinese patent with the publication number CN110037746A "Capsule-type digestive tract liquid collection device controlled by external magnetic field and its capsule body" provides a capsule-type digestive tract liquid collection device controlled by external magnetic field, as well as the capsule body. In this state, due to the constraints of the limiting structure composed of the rotation limit pin on the capsule inner shell and the rotation limit groove on the capsule outer shell, and the first magnetic column fixed on the capsule inner shell and fixed on the There is an included angle between the magnetic poles of the second magnetic column of the outer shell of the capsule, which causes a rotational torque, so that the capsule body itself is always in a state of internal tight connection. Under the excitation of an external magnetic field, the rotation between the magnetic columns is realized, driving the inner shell The relative rotation of the body causes the dislocation of the liquid inlet, and then opens the liquid inlet to realize the collection of digestive juice; but this device is a sampling device, which does not have the ability to obtain the temperature information of the wound surface of the digestive tract system

[0003] At present, there is no published literature on digestive tract capsule endoscopy that integrates visual imaging detection and temperature information acquisition functions
