Problems solved by technology

But this invention still has the following disadvantages or deficiencies: (1), what this system adopts is the combination of a rigid tube endoscope and an OCT probe, which needs to be inserted mechanically, specifically, through the natural channels of the human body or through surgery. (2), the patient needs anesthesia to relieve pain during the examination process using the system, and the patient who is allergic to the anesthetic can only endure the discomfort of the intubation process; (3), the system requires a doctor Manual operation enters the human body, so the requirements for doctors are relatively high, and there are hidden dangers of human error
However, the invention still has the following disadvantages or deficiencies: (1), because the device does not include a swinging head mechanism, the capsule endoscope cannot scan and take pictures of the corner tissues in the body cavity, and then easily produces inspection blind spots, which is not conducive to all-round observation Detect tissue in the body cavity; (2) The device does not include an OCT imaging probe, which cannot detect tiny lesions under the surface of human viscera, and its application range is limited

Embodiment 1

[0035] The present invention provides a wireless capsule OCT (optical coherence tomography: optical coherence tomography) endoscope system, such as figure 1 As shown, the system includes: a smart capsule 100, a wearable device 200 configured to receive image data sent by the smart capsule 100 and wirelessly power the smart capsule 100, and a wearable device 200 configured to display the image data transmitted by the wearable device 200. Display 300 of data.

[0036] Such as figure 2 As shown, the smart capsule 100 includes: a capsule shell 110, an OCT imaging probe assembly installed in the capsule shell 110 (components 1111, 1112, 1113, 1114, 1115 will be described in detail below), and one end of the OCT imaging probe assembly is passed through an optical fiber The fiber coupler 111 connected to realize optical signal branching and combining, the light source module 112 connected with the fiber coupler 111 through an optical fiber, the rear of the fiber coupler 111 is conn...

Embodiment 2

[0049]The other aspects are the same as in Embodiment 1, except that: the head and the neck are connected by a pivot hinge; the swing driving part includes a cam, a push rod, a guide block and a compression spring; the cam is fixed on the motor shaft of the first motor; The ejector rod is arranged on one side of the pivot hinge, one end of the ejector rod is connected to the head through a spherical hinge, and the other end of the ejector rod is placed on the outer peripheral surface of the cam; the guide block is fixed on the inner wall of the neck and is provided for guiding The guide groove for the movement of the push rod; the compression spring is arranged on the other side of the pivot hinge and the two ends are respectively connected to the head and the neck, so that when the cam rotates from the lowest working position point to the highest working position point, the push rod overcomes the compression spring The elastic force of the head swings to the side of the compre...

Embodiment 3

[0051] Other aspects are the same as in Embodiment 1, except that the OCT imaging probe also includes a fixed reflector, and the lens assembly focuses the input beam and is reflected by the fixed reflector to the MEMS micromirror, and then transmitted through the MEMS micromirror after being reflected by the MEMS micromirror. The probe window hits the target area.

Abstract

The invention relates to a wireless capsule OCT (optical coherence tomography) endoscope system for gastrointestinal tract diagnosis and treatment. The wireless capsule OCT endoscope system comprises an intelligent capsule, a wearable device and a displayer, wherein the wearable device comprises a transmitting circuit, a transmitting coil and a data processor. The intelligent capsule comprises a capsule casing, an OCT imaging probe, an optical fiber coupler, a light source module, a photoelectric detector, an A / D (analog / digital) converter, a data transmitter, a receiving circuit and a receiving coil, wherein the capsule casing comprises a head, a neck, a body and a tail, the OCT imaging probe comprises a lens assembly, an MEMS (micro-electro-mechanical system) micromirror, a reflecting mirror and a probe window, and one beam of light of a shunt of the optical fiber coupler is reflected by the MEMS micromirror through the lens assembly and then irradiates via the probe window while another beam of light of the shunt of the optical fiber coupler is transmitted to the reflecting mirror. The wireless capsule OCT endoscope system for gastrointestinal tract diagnosis and treatment has the advantages that by the aid of the endoscope system, non-invasive detection of in-vivo tissues of humans can be achieved; the endoscope system with micron-grade high resolution is capable of imaging in real time, and omni-directional scanning can be achieved according to a swing design of the head of the capsule casing.

Description

technical field [0001] The invention relates to an endoscope system, in particular to a wireless capsule endoscope system. Background technique [0002] As people's pace of life continues to accelerate, the incidence of digestive system diseases caused by work stress and unbalanced diet is increasing all over the world. At the same time, because the gastrointestinal tract is directly connected to the anus in terms of physiological structure, it is easily infected by foreign bodies and pathogens outside the human body, so that clinically the incidence of gastrointestinal diseases is higher than that of other parts of the disease. For this reason, medical staff must conduct more and more detailed observations of the human gastrointestinal tract. [0003] Most of the core technologies of traditional endoscopes use optical fiber bundles for light transmission and imaging, or CCD technology for imaging. This type of endoscope can only observe from the surface of the tissue. For ...
