输尿管镜手术是通过一细长的窥镜，经尿道、膀胱、输尿管扣进入0.20.5cm直径的输尿管，在直视下或借助电视监视系统，可以很清晰地观察到输尿管内的病变，如有结石、肿瘤等，对输尿管疾病进行诊断与。下面内窥镜设备维修人员来讲讲手术操作中输尿管镜的正确与操作要点。

Ureteroscopic surgery is to enter the ureter with a diameter of 0.2 to 0.5 cm through the urethra, bladder and ureteral buckle through a slender endoscope. Under direct vision or with the help of a television monitoring system, the pathological changes in the ureter can be clearly observed, such as stones, tumors, etc., to diagnose and treat ureteral diseases. The following endoscopic equipment maintenance personnel will talk about the correct operation of ureteroscope and key points of operation.

避免碰撞软镜：拿取及退还软镜时，须小心谨慎，放置稳妥，避免碰撞，受压及坠落于地。

Avoid collision with the soft mirror: Take and return the soft mirror carefully and place it securely to avoid collision, compression and falling to the ground.

专人操作使用：因术者的使用经验以及操作的持续时间是导致输尿管软镜损伤的主要因素，为确保软镜的正常使用，避免因操作不熟练造成软镜的损伤，我们规定输尿管软镜只能由具有操作经验的结石组手术医生专人使用，其他医疗组不能使用，如有需要，须由结石组医生操作。

Specially assigned person for operation: The use experience of the operator and the duration of the operation are the main factors leading to the damage of the flexible ureteroscope. In order to ensure the normal use of the flexible ureteroscope and avoid the damage of the flexible ureteroscope caused by unskilled operation, we stipulate that the flexible ureteroscope can only be used by the specially assigned person of the surgeon in the calculus group with operation experience, and cannot be used by other medical groups. If necessary, it must be operated by the surgeon in the calculus group.

术中使用输尿管扩张鞘便于软镜置入：对确定用输尿管软镜碎石手术的患者，术前2周常规在膀胱镜室留置输尿管支架管，对输尿管进行被动扩张，有利于术中顺利放置软镜扩张鞘，便于软镜置入。

During the operation, the ureteral dilation sheath is used to facilitate the placement of the flexible endoscope: For patients who are determined to use the flexible ureteroscope for lithotripsy, the ureteral stent tube is routinely placed in the cystoscope room 2 weeks before the operation to passively dilate the ureter, which is conducive to the smooth placement of the flexible ureteroscope dilation sheath during the operation and the placement of the flexible ureteroscope.

输尿管软镜碎石手术中，输尿管扩张鞘的使用可明显改善碎石视野，保证冲洗速度，降低肾盂内压，减少镜体轴线转动阻力，减少镜体反复进出输尿管而可能赵成的黏膜损伤，缩短手术时间并提高碎石成功率，减少输尿管软镜的损耗。

During ureteroscopic lithotripsy, the use of ureteral dilating sheath can significantly improve the lithotripsy field of vision, ensure the flushing speed, reduce the internal pressure of the renal pelvis, reduce the rotation resistance of the lens body axis, reduce the mucosal damage of Zhao Cheng caused by repeated access of the lens body to the ureter, shorten the operation time, improve the success rate of lithotripsy, and reduce the loss of ureteroscopic lithotripsy.

正确置入钬激光光纤、导石篮等附件：有研究认为，软镜的主要损害原因是由于一些工具，如光纤、取石钳等通过工作通道造成软镜的损伤。因此置入光纤时须使输尿管软镜保持伸直状态，光纤顶端应保持外伸超出输尿管软镜2~3mm。

Correct placement of holmium laser optical fiber, stone guide basket and other accessories: some studies believe that the main cause of damage to the soft mirror is that some tools, such as optical fiber, stone forceps, cause damage to the soft mirror through the working channel. Therefore, the flexible ureteroscope must be kept straight when the optical fiber is inserted, and the top of the optical fiber should be kept extended beyond the flexible ureteroscope by 2-3 mm.

输尿管镜作为现代临床医学诊疗的重要设备之一，其维护也显得尤为重要，其中使用前后的检查以及清洁需要多做工作，更多相关内容就来我们网站http://www.jiangrenyiliao.cn进行咨询！

As one of the important equipment of modern clinical medicine, the maintenance of ureteroscope is also particularly important. More work needs to be done before and after the use of ureteroscope for inspection and cleaning. More relevant information can be found on our website http://www.jiangrenyiliao.cn Consult!
