技术领域technical field
本实用新型涉及外科手术器械技术领域，具体涉及一种胸腔镜手术术中用镜头清洁除雾装置。The utility model relates to the technical field of surgical instruments, in particular to a lens cleaning and defogging device in thoracoscopic surgery.
背景技术Background technique
胸腔镜手术是电视胸腔镜手术(Video-Assisted Thoracic Surgery，VATS)的简称。胸腔镜手术被视为二十世纪末期胸外科界革命性的一大突破，是胸外科微创手术的代表性术式，已经逐步在国内各三甲医院及区域中心医院普及。Thoracoscopic surgery is the abbreviation of Video-Assisted Thoracic Surgery (VATS). Thoracoscopic surgery is regarded as a revolutionary breakthrough in the field of thoracic surgery at the end of the 20th century. It is a representative procedure of minimally invasive surgery in thoracic surgery, and it has been gradually popularized in domestic tertiary hospitals and regional central hospitals.
从技术层面上看，胸腔镜手术通过两至三个“钥匙孔”进出手术器械，其中“观察孔”由腔镜镜头占据，镜头连接光纤同时接成像设备；术者在电视影像(Video-assisted)的监视辅助下完成过去由传统开胸进行的手术操作。其本质是用“腔镜”做手术(或称为腔镜外科)，相对于传统的开胸手术具有创伤小、恢复快、住院时间短等技术特点，其本质与开胸手术的原理相同，但改变了传统的手术入路、分离步骤、结扎与缝合方式，尤其是手术过程中的观察方式由直接肉眼观察转换为经内镜观察，后者可将视野放大4-6倍，优势明显。From a technical point of view, thoracoscopic surgery enters and exits surgical instruments through two to three "keyholes". ) to complete the operation performed by traditional thoracotomy in the past. Its essence is to use "laparoscopy" for surgery (or called laparoscopic surgery). Compared with traditional thoracotomy, it has the technical characteristics of less trauma, faster recovery, and shorter hospital stay. Its essence is the same as that of thoracotomy. However, the traditional surgical approach, separation steps, ligation and suturing methods have been changed. In particular, the observation method during the operation has been changed from direct naked eye observation to endoscopic observation. The latter can magnify the field of view by 4-6 times, which has obvious advantages.
在实际手术操作的过程中，尽管骨性胸廓的支撑能为腔镜下操作提供一定空间，但在这样有限的空间里，在应用电刀、超声刀、能量平台等高能器械分离创面、离断组织和血管的过程中，不可避免的会有油滴、血滴、水雾等污染腔镜镜头。加之自腔镜套管(Trocar)切口部位沿镜身流下的血污，腔镜镜头会反复被污染，需在术中不断终止操作，将镜头撤至胸腔外，应用干净纱布擦试。将镜头放回胸腔内后，由于手术室室温(20-24℃)和胸腔内温度(37℃)存在差异，镜头多会起雾，需重新擦试，或在热水中长时间浸泡加温后再次置入胸腔。估算单次处理腔镜镜头污染的耗时在1分钟以上，若多次污染，会大大延长手术时间，加大麻醉药用量，增加术者精力、体力付出，且不论因重新布置视野导致的反复牵拉脏器、重复手术操作等可能导致术中出血、损伤等并发症。因此，寻找合理有效的方法，最大限度避免腔镜污染、起雾等问题，是胸腔镜手术实际应用中需解决的“小”问题，却是十分必要的问题。In the actual operation process, although the support of the bony thorax can provide a certain space for the endoscopic operation, in such a limited space, the use of high-energy instruments such as electric knife, ultrasonic knife, and energy platform to separate the wound surface In the process of tissue and blood vessels, it is inevitable that oil droplets, blood droplets, water mist, etc. will contaminate the laparoscopic lens. In addition to the blood stains that flowed from the incision of the endoscopic trocar along the endoscope body, the endoscopic lens will be repeatedly contaminated. It is necessary to stop the operation during the operation, withdraw the lens outside the thoracic cavity, and wipe it with clean gauze. After putting the lens back into the chest cavity, due to the difference between the room temperature (20-24°C) in the operating room and the temperature in the chest cavity (37°C), the lens will often fog up and need to be wiped again, or soaked in hot water for a long time to warm up It was reinserted into the chest cavity. It is estimated that it takes more than 1 minute to deal with the contamination of the endoscopic lens for a single time. If there is multiple contamination, the operation time will be greatly prolonged, the amount of anesthetics will be increased, and the energy and physical exertion of the operator will be increased. Repeated pulling of organs and repeated surgical operations may lead to intraoperative bleeding, injury and other complications. Therefore, finding a reasonable and effective method to avoid problems such as endoscopic contamination and fogging to the greatest extent is a "small" problem that needs to be solved in the practical application of thoracoscopic surgery, but it is a very necessary problem.
