Endoscopic surgery is a model for the application of high technology such as electronics, optics, and cameras in minimally invasive clinical disciplines. Widely used in hospitals at all levels.
Endoscopic instruments and equipment systems will be called differently when they are applied to various clinical departments, such as: ventriculoscopy, thoracoscopy, hysteroscopy, ureteroscopy, prostate resectoscopy, intervertebral discoscopy, arthroscopy, laparoscopy, etc., Among them, laparoscopy and hysteroscopy are the most popular. Different from traditional surgery, the operation is performed in a closed cavity. Therefore, the quality of instruments and equipment directly affects the effect of surgery, and the correct use of instruments and equipment is also directly related to The success of the surgery. Now there are many brands of endoscopes on the market, each with its own advantages and disadvantages. However, the basic principles remain the same.
The medical endoscope system is mainly composed of equipment system and 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 by various departments. I will not introduce it in detail here. Let us mainly discuss the structural composition 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 compression system, electrocoagulation and electrocution system, dynamic ablation system, irrigation and suction system, etc.
1. Medical endoscope camera imaging system
The system includes a display and a camera. There are two types of monitors: conventional CRT and LCD, and two types of cameras: single CCD and 3CCD. Now the high-end customers are mostly LCD monitors with 3CCD cameras.
2. Medical endoscope 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. Medical endoscope light source system
Also called cold light source. Cold light source bulbs are filled with halogen and gas. Its outstanding feature is that the light is strong and the color temperature is similar to that of sunlight. Covers the entire wavelength range from ultraviolet to infrared.
4. Medical endoscope artificial pneumoperitoneum system
Connect the pneumoperitoneum to the carbon dioxide cylinder, unscrew the valve on the cylinder, and then turn on the pneumoperitoneum. According to the needs of the operation, select the pressure preset value, when the intra-abdominal pressure exceeds or falls below the set value, the automatic carbon dioxide pneumoperitoneum machine can automatically start or stop gas injection.
5. Medical endoscope liquid pressurization system
Systems such as joint pumps, uterine distension pumps, and bladder pumps are mainly used to pressurize fluids into a cavity, and then use instruments to perform surgery in the cavity.
6. Medical endoscope electrocoagulation and electrocution system
High-frequency electrocautery is often used in both general open surgery and minimally invasive surgery.
7. Medical endoscope dynamic ablation system
In sinusoscopy and arthroscopic surgery, powered ablation systems and ion ablation knives are often used. Although these two devices are expensive, they greatly shorten the intraoperative time and reduce the surgical risk.
Medical endoscopes are frequently used in clinical work, and endoscopes are prone to various failures. In order to reduce the occurrence of equipment failures as much as possible, a dedicated laparoscopic operating room should be set up to reduce the movement and damage of the instruments, and the specialist laparoscopic nurses should be assigned to use and maintain them. How to use it, 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 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 in the actual maintenance is the ordering of replacement parts. Manufacturers rarely sell accessories. If the instrument is damaged, it is better to deal with it, and you can directly find the endoscope instrument manufacturer.
