技术领域technical field
本实用新型涉及医疗器械技术领域，特别是涉及一种带锁定线双腔猪尾导管。The utility model relates to the technical field of medical instruments, in particular to a double-cavity pigtail catheter with locking lines.
背景技术Background technique
猪尾导管，因端部卷曲，末端形似猪尾而得名，猪尾导管在泌尿科的肾、输尿管、膀胱手术中取得了广泛的应用。使用猪尾导管内引流的患者在术后的管理趋于简单化，因导管内置，患者可早期活动，减少了感染机会，护理工作量明显减少，患者术后恢复快，住院时间明显缩短。但临床上，有些病人体内的猪尾导管发生了异位，造成其失去作用，严重时需手术取出，给病人造成巨大的身体伤害和额外的费用支出。Pigtail catheter, named for its curled end and pigtail-like shape, has been widely used in urological kidney, ureter, and bladder operations. The postoperative management of patients using pigtail catheter drainage tends to be simplified. Because of the built-in catheter, patients can move early, reduce the chance of infection, significantly reduce the nursing workload, and the patient recovers quickly after surgery, and the hospital stay is significantly shortened. But clinically, the pigtail catheter in some patients is misplaced, causing it to lose its function. In severe cases, surgery is required to remove it, causing huge physical injury and additional expenses to the patient.
