Description

A kind of esophageal endoscope sampler

technical field

The invention belongs to the field of medical instruments, in particular to an esophageal endoscope sampler.

Background technique

Traditional endoscopes include gastroscopes, colonoscopes, laryngoscopes, hysteroscopes, etc. All of these products have similar shortcomings, such as easily causing nausea and vomiting in patients, causing patients to feel painful. Capsule endoscopy (capsule endoscopy), as a new scientific and technological product of medical development, is a medical instrument made into a capsule-shaped endoscope for examining the human intestinal tract. The capsule endoscope enters the body through the patient's mouth, and uses its lens components to take close-up shots of the internal conditions of the human body, spying on the health status of the human stomach, esophagus and other parts, which can be used to help doctors diagnose patients, and at the same time reduce the traditional pain caused by patients.

The existing capsule endoscope has a single function, a single angle of ingestion, a limited shooting range, and limited diagnostic image data, and is especially not suitable for simultaneous use with a sampler. Therefore, it is an urgent problem to be solved to provide an endoscope that can clearly photograph the inside of the human body and a medical device that can cooperate with living body sampling, which is conducive to improving the accuracy and precision of medical diagnosis.

The endoscope sampler also includes a sampling device for sampling the lumen of the esophagus.

The sampling device (9) includes an air pump (91), an air release valve (92), a conduit (93), a rubber ring (94) and several sampling brushes (95) distributed on the rubber ring (94).

The rubber ring (94) is arranged on the outer periphery of the pulling wire (8), and the conduit (93) is connected to the rubber ring (94) and the air release valve (92).

The beneficial effects of the present invention are:

1. Set the endoscope sampler in a streamlined shape with a large front and a small rear for easy removal.

2. The light source component is placed at the rear to avoid the impact of the light source component on the camera's field of view; the light is evenly projected to the front of the capsule body through the reflector, which can reduce the volume of the capsule.

3. A rubber ring with a sampling brush and an air pump and an air release valve connected to it are set on the outer periphery of the traction line. Sampling can be performed while using the endoscope to realize the synergistic effect of spying and sampling; and the air pump can be used during sampling. Pressurize the rubber ring of the sampling brush, and the rubber ring of the sampling brush bulges, and the sampling is successfully realized; after sampling, the air release valve deflates, so that the rubber ring of the sampling brush fits on the traction line, which is convenient for endoscopy Sampling and access to the mirror sampler;

4. Set the fisheye camera, adjust the field of view and the definition of the macro distance, and realize the clear shooting and accurate positioning and sampling of the esophagus image by the endoscope sampler;

5. The light source component is placed behind, and the light is projected evenly through reflection, which can reduce the volume of the capsule;

6. The image processing and transmission unit is also equipped with a wifi module, which can transmit or receive signals from the terminal or handheld.

detailed description:

Please refer to FIG. 1 , which is a schematic structural view of a preferred embodiment of the present invention.

An esophageal endoscope sampler, comprising a capsule body 1, the capsule body 1 is streamlined with a large front part and a small rear part, and a camera 2 is arranged in the capsule body 1, which is arranged at the front part of the capsule body 1 for taking pictures The image in the cavity; the light source assembly 3, placed behind the camera 2, is used to provide illumination light for the camera 2; the reflector 4, located on both sides of the light source assembly 3, is arranged correspondingly, and is used to reflect the light of the light source assembly 3 to the capsule body The front end part of 1; Optical channel 5, the passage that is formed by the side wall of reflector 4, capsule body 1 and the outer wall of camera 2 jointly, is used for reflecting the light on reflector 4 to the front end part of capsule body 1; Image processing The transmission unit 6 is used for processing and storing images collected by the camera 2 . The capsule body 1 also includes a power supply module 7; the image processing transmission unit (6) is located between the light source assembly (3) and the power supply module (7). Preferably, the camera 2 is a fisheye camera with a field of view of 180°. The light channel can be a hollow structure or filled with a light-guiding polymer material. Preferably, the light source assembly 3 is an LED lamp ring. The image processing and transmission unit 6 is also provided with a wifi module, which can transmit or receive signals from a terminal or a handset. When the endoscope sampler is working, at first, the power supply module 7 is powered, and then the power supply module 7 distributes electricity to each working unit. The light source assembly 3 emits light after being powered on, and projects the light evenly onto the front end of the capsule body 1 through the reflector 4 and the optical channel 5; the camera 2 collects high-definition images and transmits them to the image processing and transmission unit 6 for processing, storage, and wireless communication via wifi. Transmit to a terminal or handset. The terminal software can control the camera 2 and the light source assembly 3 (photographing, video recording, LED brightness, etc.) through the wifi module.

The rear portion of the capsule body 1 is provided with a traction line 8, which extends outside the capsule body 1. One end of the traction line 8 is connected to an external power supply, and the other end is connected to the power module 7. The traction line 8 is wrapped with a non-toxic anti- Pull the electric wire of material, can supply power to power supply module 7.

The esophageal endoscope sampler also includes a sampling device 9 for sampling the lumen of the esophagus. The sampling device 9 includes an air pump 91 , an air release valve 92 , a conduit 93 , a rubber ring 94 and several sampling brushes 95 distributed on the rubber ring 94 . The rubber ring 94 is arranged on the outer periphery of the pulling wire 8 , and the conduit 93 is connected with the rubber ring 94 and the deflation valve 92 . When the endoscopic sampler enters the human body to take a sample, close the air release valve 92, pressurize the air pump 91, and the gas enters the rubber ring 94 from the conduit 93, and the rubber ring 94 bulges. When being dragged by the outside, the rubber ring The sampling brush 95 on the periphery of 94 constantly rubs against the esophagus to collect the liquid with cells, so as to realize the purpose of sampling the esophagus. When the sample is taken, the air release valve 92 is opened, and the rubber ring 94 deflates, and is fitted on the traction wire 8, so as to facilitate the taking out of the endoscope sampler.

Of course, the above illustrations are only preferred implementation modes of the present invention, and are not intended to limit the application scope of the present invention. Therefore, all equivalent changes on the principle of the present invention shall be included in the protection scope of the present invention.
