Endoscopic surgery is a model of high-tech applications in minimally invasive clinical disciplines such as electronics, optics, and photography. With the reform of the national medical system, the advancement of medical technology, and the popularization of advanced medical equipment, endoscopic equipment systems are becoming more and more It is widely used in hospitals at all levels.
The endoscope equipment system will be called differently when it is used in various clinical departments, such as: ventriculoscopy, thoracoscopy, hysteroscopy, uretero-nephroscope, resection of the prostate, intervertebral discs, arthroscopy, laparoscopy, etc. Among them, laparoscopy and hysteroscopy are the most popular applications. Unlike traditional surgery, they are performed in a closed cavity. Therefore, the quality of the equipment directly affects the effect of the operation, and the correct use of the equipment is also directly related to The operation was smooth and successful. There are many brands of endoscopes in the domestic market, each with its own advantages and disadvantages. However, the basic principles are the same.

The composition of the endoscope system
The medical endoscope system is mainly composed of an equipment system and a surgical instrument system. The surgical instrument system is mainly classified according to the department or the name of the operation. There are endoscopes, special instruments, surgical instruments and disposable surgical consumables used in each department. I won't introduce it in detail here, but let's mainly discuss the structure of the equipment system.
In the equipment system, we can usually be divided into: camera imaging system, image recording system, light source system, artificial pneumoperitoneum system, liquid pressurization system, electrocoagulation and electrocutting system, power ablation system, flushing and suction system, etc.
(1) Camera imaging system:
The system includes a monitor and a camera. There are two types of monitors: conventional CRT and liquid crystal. There are two types of cameras: single CCD and 3CCD. Nowadays, most high-end users are LCD monitors with 3CCD cameras.
(2) Image recording system:
Many hospitals now choose computer-based graphic workstations. The system is divided into two parts: computer hardware and graphic acquisition software.
(3) Light source system:
Also known as cold light source. The cold light source bulb is filled with halogen and gas, and its output power is 70-400W. Now 300W argon light source is the mainstream product. Its outstanding feature is the strong light and the color temperature is 5600-6000k, which is similar to sunlight. Covers the entire band from ultraviolet to infrared.
(4) Artificial pneumoperitoneum system:
Connect the insufflator to the carbon dioxide cylinder, unscrew the valve on the cylinder, and then turn on the insufflator. According to the needs of the operation, select the preset pressure value. When the pressure in the abdominal cavity exceeds or falls below the set value, the automatic carbon dioxide insufflator can automatically start or stop gas injection.
(5) Liquid pressurization system:
Systems such as joint pumps, dilatation pumps, and bladder pumps are mainly used to pressurize liquids into a cavity, and then use instruments to perform operations in the cavity.
(6) Electrocoagulation and cutting system:
High-frequency electrocautery is often used in ordinary open surgery and minimally invasive surgery.
(7) Power ablation system:
In sinusoscope and arthroscopic surgery, the power planing system and ion ablation knife are often used. Although these two devices are expensive, they greatly shorten the intraoperative time and reduce the surgical risk.
(8) Flushing suction system:
The flushing flow rate of the equipment should be at least 1L/min.
Endoscopes are frequently used in clinical work, and endoscopes are prone to various failures. In order to minimize the occurrence of equipment failures, a dedicated laparoscopic operating room should be set up to reduce the movement and damage of the instrument, and a specialist nurse of endoscopy should be assigned to use and maintain it. The specialist nurse of endoscopy should be fully familiar with the performance and structural characteristics of the instrument and its accuracy The method of use, strictly implement the operating procedures, and pay attention to the three links of preoperative inspection, intraoperative troubleshooting, and timely postoperative maintenance.
If there is a problem with the equipment, the first thing to do is to take emergency maintenance, because this can solve the small and medium faults that account for about 85% of the faults. The most difficult problem to solve during actual maintenance is the ordering of replacement parts. Manufacturers rarely sell accessories. If the equipment is damaged, it is better to deal with it, and you can directly contact the manufacturer. At present, many hospitals also use domestically-made equipment. However, because the design level and production technology have not reached the international advanced level, it is relatively easy to be damaged and the matching of the equipment is not enough. Usually, the same equipment of the same brand cannot be matched after replacement.
