"Endoscope" is an endoscope, which is a kind of testing instrument that integrates optics, ergonomics, precision instruments, modern electronics, mathematics and software.
1. Rigid endoscope VS flexible endoscope
There are many types of electronic endoscopes, which can be divided into soft endoscopes and rigid endoscopes according to the degree of softness and hardness.
Flexible endoscope: a type of endoscope with a soft and bendable body.
Rigid endoscope: The main body of the mirror body cannot be bent or twisted, which can better complete cutting, separation, extraction, etc.
There is no distinction between hard mirrors and soft mirrors, but produced according to different scopes of application.
Rigid endoscopes are endoscopes in which the distal end of the insertion part is bendable or all are made of metal and are rigid. According to the shape, rigid endoscopes can be divided into optical tubes, rigid fiber endoscopes and rigid electronic endoscopes.
The optical tube and rigid fiberscope are composed of three parts: objective lens system, transfer system (image transfer system) and eyepiece system.
With the development of electronic technology, semi-rigid/rigid electronic endoscopes have been developed on the basis of simple optical tubes and rigid fiberscopes. The rigid electronic endoscope is composed of a light guide connector, a camera host connector, an operation part, an insertion part, and a tip part. Compared with rigid endoscopes, the most significant advantage of flexible endoscopes is that they can be bent.
Flexible endoscopes are divided into fiber endoscopes and flexible electronic endoscopes. The fiberscope is composed of a flexible insertion part, a light guide plug part, an operation part and an eyepiece part or an objective lens. The light emitted by the light source device is transmitted through the light guide inside the endoscope, and the illumination light at the tip is emitted to the observation site. The image guide beam inside the endoscope transmits the light from the subject incident from the objective lens to the eyepiece part to realize imaging observation. Different from endoscopes composed of traditional optical lenses, fiber endoscopes use image transmission fibers. Due to the characteristics of the fiber optic material, it can still transmit images even when it is bent.
The flexible electronic endoscope is composed of three parts: the insertion part, the operation part and the connection part. The medical personnel can adjust the angle of the endoscope through the operation part, and can send in air or water at the same time. There is an instrument hole in the operation part, and the endoscopic diagnosis and treatment accessories are inserted and removed from here for operation. The tip of the insertion part has built-in components such as objective lens and illumination lens, and is an important part of the endoscope to realize diagnosis and treatment.
The connection part is connected with the light source and the image processing device through cables, and is provided with a ventilation joint and a suction joint at the same time, so as to realize air and water supply to the endoscope pipeline.
2. What can hard/soft endoscopy do?
Flexible endoscope: mainly through the natural cavity of the body to complete inspection, diagnosis and treatment, such as gastroscope, colonoscope, bronchoscope, etc., mainly enter the human body through the digestive tract, respiratory tract and urinary tract of the human body.
Clinically, soft mirrors are most commonly used for the capture of foreign bodies, such as esophageal blockage; pathological sampling in the cavity; and examination of the integrity of the mucosa in the cavity.
Rigid endoscopy: mainly through sterile surgical incisions to enter the sterile tissues, organs and sterile chambers of the body, such as laparoscopy, thoracoscopy, arthroscopy, discoscopy, ventriculoscopy, etc.
Unlike soft mirrors, hard mirrors are not restricted by the body's natural orifice, and can cooperate with each other through different lenses to perform more and more complicated tasks under the supervision of the endoscope.
3. Endoscopy VS traditional surgery
degree of damage
Traditional surgery: The surgical incision is larger and the bleeding is more.
Endoscopic minimally invasive surgery: the wound is small, and even two band-aids can solve it.
repair cycle
Traditional surgery: The wound is larger, the repair time is longer, and the more complicated the operation, the longer the recovery period.
Minimally invasive surgery under endoscope: small surgical trauma, less postoperative pain, faster healing, small incision and small scar.
duration of pain
Traditional surgery: For fur children who cannot tolerate pain, traditional surgery will take at least 3-5 days of pain.
Minimally invasive surgery under the endoscope: No sensation on the second day, you can move freely.
Indications
Traditional surgery: The types of surgery published at home and abroad belong to traditional surgery.
Endoscopic minimally invasive surgery: Not all surgeries can be done through endoscopes, such as internal fixation of fractures, complex orthopedic surgeries such as TTA and TPLO, still need to be done through traditional surgeries.
Endoscopy represents a remarkable convergence of medical knowledge and cutting-edge technology, enabling healthcare professionals to delve into the inner workings of the human body with precision and care. This innovation has transformed diagnostic practices, improved patient outcomes , and empowered medical practitioners to diagnose and Treat a wide range of conditions in a minimally invasive manner. As technology continues to advance, the future of endoscopy holds promise for even more refined techniques, further enhancing our ability to understand and care for the intricacies of the human body.
