What Are the Different Types of Endoscopy Equipment?

Endoscope equipment is a medical appliance used to collect internal conditions. The endoscope enters the human body through a natural channel of the human body or a small incision made through surgery, and is composed of a flexible part, a light source and a group of lenses. When used, the endoscope is introduced into a pre-examined organ to directly observe the changes in the relevant part.

classification

Classification according to its development and imaging structure: can be divided into:

1. Hard tube endoscope (endoscope).

2. Optical fiber (hose type) endoscope.

3. Electronic endoscope.

4. Endoscopic ultrasound.

5. Capsule endoscope. ^[1]

According to the function of the endoscope, it can be divided into:

1. Single-function mirror: refers to an observation mirror with no working channel and only an optical system.

2. Multifunctional mirror: In addition to the function of an observation mirror, in the same lens body, it also has at least one working channel, which has a variety of functions such as lighting, surgery, irrigation and suction.

According to whether the mirror body can change direction, it can be divided into:

1. Hard mirror: prism optical system, the biggest advantage is clear imaging, can be equipped with multiple working channels, select multiple perspectives.

2. Flexible soft mirror: optical fiber optic system, the biggest feature of this fiber endoscope is that the lens part can be manipulated by the operator to change the direction and expand the scope of application, but the imaging effect is not as good as the hard lens.

According to the area reached by the endoscope, it can be divided into:

1. Endoscopes for the digestive tract: rigid tube esophagus, fiber esophagus, electronic esophagus, ultrasonic electronic esophagoscopy, fiber gastroscope, electronic gastroscope, ultrasonic electronic gastroscope, fiber duodenoscope, electronic duodenum Colonoscopy, fiber enteroscopy, electronic enteroscopy, fiber colonoscopy, electronic colonoscopy, fiber sigmoidoscopy, and rectoscopy.

2. Endoscopes for the respiratory system: rigid tube laryngoscope, fiber laryngoscope, electronic laryngoscope, fiber bronchoscope, electronic bronchoscope, thoracoscopy and mediastinoscopy.

3. Endoscopy for peritoneal cavity: there are rigid tube type, optical fiber type, and electronic surgical type laparoscope.

4. Endoscopy for biliary tract: rigid tube cholangioscope, fiber cholangioscope, electronic cholangioscope, and son-in-child cholangioscope.

5. Endoscopy for the urinary system: 1) Cystoscopy: can be divided into cystoscopy for examination, cystoscope for ureteral intubation, cystoscope for surgery, cystoscope for teaching, cystoscope for photography, pediatric cystoscope and Female cystoscope. 2) Ureteroscope. 3) Nephroscope.

6. Endoscopy for gynecology: colposcope and hysteroscope.

7. Endoscopy for blood vessels: endovascular endoscopy.

8. Endoscope for joints: Arthroscopy. ^[2]

Advantages of the endoscope:

Endoscope technology has unique advantages, it can extend people's line of sight, and can change the direction of sight arbitrarily to accurately observe the true condition of the inner surface of the object, which cannot be replaced by other detection instruments. The advantages of endoscopes are as follows:

(1) The image is clear, the color is realistic, and the resolution is high. The endoscope image is specially processed to enlarge the image, which is especially suitable for small things.

(2) It has the functions of video recording and photographing, and saves the picture for easy viewing and continuous contrast observation, reducing the time of endoscopy.

(3) It avoids the shortcomings such as easy breakage of optical fiber, easy attenuation of light guide brightness, and easy distortion of image magnification.

(4) The camera uses a scratch-resistant and oil-resistant glass shell, precision mold injection molding, and some parts are made of stainless steel die-casting to ensure that the product is durable, waterproof, wear-resistant, and corrosion-resistant, which improves the durability in harsh environments.

(5) Equipped with an external rechargeable battery, a portable high-definition color LCD display, which greatly facilitates long-term outdoor use, and can be equipped with a special video capture card for real-time capture, which can be achieved with one click. It can be connected to a monitor or monitor to display the detection image in real time with high definition. Realize 1 person operation, multiple people can watch at the same time. Convenient for diagnosis, consultation and teaching.

(6) From the remote probe to the handheld handle, the industrial electronic endoscope has strong water resistance and excellent resistance to minerals, synthetic lubricants, aviation fuel, kerosene, gasoline and diesel.

(7) Endoscopes are cost-effective and value-for-money. The price and performance of this endoscope are very competitive in the market. It is your first choice for pipeline video detection and precision instrument detection.
