Types of endoscopy

Bronchoscopy Simulator

Endoscope is a kind of medical instrument commonly used in clinical practice. It can be entered into the human body through the lumen or small incision of the operation, so that doctors can intuitively diagnose and treat the lesions. It is widely used in general surgery, urology, gastroenterology and respiratory department.

In terms of categories, they include:

Bronchoscope (for respiratory department),

Thoracoscopy, mediastinoscopy, etc. (for cardiothoracic surgery),

Nephroscope, electroscope, etc. (for urology),

Nasopharyngoscope, laryngoscope, otoscope, etc. (for otolaryngology),

Gastroscope, enteroscope, esophagoscope, choledochoscope, etc. (used in gastroenterology),

Laparoscope, cystoscope, ureteroscope, nephroscope, electroscope, etc. (used in urology).

The hardness of the mirror body is classified as follows:

As a whole, the endoscopic system is composed of the mirror body, light source, image processing host and monitor.

Endoscopy can be divided into: whether the lens body is curved or not and how it enters the human body:

Flexible endoscope and rigid endoscope:

1) Rigid endoscope: not bable, mainly through surgical incision into the human body.

Generally, minimally invasive abdominal surgery requires 3-4 holes (imaging observation holes, main operating holes of surgical instruments, secondary operating holes, etc.), which are more applicable to departments than soft mirrors, mainly general surgery, thoracic surgery, urology, obstetrics and gynecology, orthopedics. It mainly includes laparoscopy, thoracoscopy and arthroscopy.

2) Flexible endoscope: It can bend freely and go deep into the body mainly through the natural cavity of the human body.

The lens body is long and flexible, the photoelectric signal transmission distance is long, the insert part of the lens body is small in diameter, and the function integration is rich, which has higher requirements for the process and technology. It is applied to digestive endoscopy and respiratory endoscopy and other departments, including gastroscopy, colonoscopy, bronchoscopy, etc.
