醫(yī)用內(nèi)窺鏡系統(tǒng)主要由設(shè)備系統(tǒng)與手術(shù)器械系統(tǒng)組成。手術(shù)器械系統(tǒng)主要按科室或手術(shù)名稱來分類。有各科使用的內(nèi)窺鏡、專用器械、配合設(shè)備使用的手術(shù)器械和一次性手術(shù)耗材。這里就不詳細(xì)介紹了,下面我們主要討論一下設(shè)備系統(tǒng)的結(jié)構(gòu)組成。
Medical endoscope system is mainly composed of equipment system and surgical instrument system. The surgical instrument system is mainly classified by department or surgical name. There are endoscopes, special instruments, surgical instruments used with equipment and disposable surgical consumables used by various departments. It will not be introduced in detail here. Next, we will mainly discuss the structure of the equipment system.
在設(shè)備系統(tǒng)中我們通??梢苑譃椋簲z像顯像系統(tǒng),影像記錄系統(tǒng),光源系統(tǒng),人工氣腹系統(tǒng),液體加壓系統(tǒng),電凝電切系統(tǒng),動(dòng)力消融系統(tǒng),沖洗吸引系統(tǒng)等等。
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 electrocautery system, dynamic ablation system, flushing and suction system, etc.
(1)攝像顯像系統(tǒng):該系統(tǒng)包括顯示器和攝像機(jī)。顯示器有常規(guī)的CRT和液晶兩種,攝像機(jī)有單CCD和3CCD兩種?,F(xiàn)在使用客戶多是液晶顯示器配3CCD攝像器。
(1) Camera imaging system: the system includes a display and a camera. There are conventional CRT and LCD displays, and single CCD and 3CCD cameras. Now most customers use LCD with 3CCD camera.
(2)影像記錄系統(tǒng):現(xiàn)在很多醫(yī)院都選擇以電腦為基礎(chǔ)的圖文工作站。該系統(tǒng)分兩部分:電腦硬件和圖文采集軟件。
(2) Image recording system: now many hospitals choose computer-based graphic workstation. The system is divided into two parts: computer hardware and graphic acquisition software.
(3)源系統(tǒng):又稱冷光源。冷光源燈泡中充有鹵素和氙氣兩種,其輸出功率為70-400W。現(xiàn)在300W氙光源是主流的產(chǎn)品。其突出特點(diǎn)是光線強(qiáng)烈,色溫5600-6000k,與太陽光類似,涵蓋了從紫外線到紅外線的整個(gè)波段。
(3) Source system: also known as cold light source. The cold light source bulb is filled with halogen and xenon, and its output power is 70-400w. Now 300W xenon light source is the mainstream product. Its outstanding feature is strong light, color temperature 5600-6000k, similar to sunlight, covering the whole band from ultraviolet to infrared.
(4)人工氣腹系統(tǒng):將氣腹機(jī)與二氧化碳鋼瓶連接好,并旋開鋼瓶上的閥門,然后開啟氣腹機(jī),根據(jù)手術(shù)的需要,選擇壓力預(yù)設(shè)值,當(dāng)腹腔內(nèi)壓力超過或低于設(shè)定值時(shí),全自動(dòng)二氧化碳?xì)飧箼C(jī)可自動(dòng)開始或停止注氣。
(4) Artificial pneumoperitoneum system: connect the pneumoperitoneum machine with the carbon dioxide cylinder, unscrew the valve on the cylinder, and then open the pneumoperitoneum machine. According to the needs of surgery, select the preset pressure. When the pressure in the abdominal cavity exceeds or falls below the set value, the full-automatic carbon dioxide pneumoperitoneum machine can automatically start or stop gas injection.
