一种腹腔穿刺引流装置A kind of abdominal puncture and drainage device

技术领域technical field

本实用新型涉及医疗设备领域，特别涉及一种腹腔穿刺引流装置。The utility model relates to the field of medical equipment, in particular to an abdominal cavity puncture and drainage device.

背景技术Background technique

目前，临床上心脏、肝脏、肾脏等发生病变时均能产生腹水，当腹腔内液体增加超过200ml 即可作为一种病征，临床在查找病因对症治疗的同时，还需要对腹水进行引流。医生通常对腹腔积液的病人实行腹腔穿刺引流，为病人将腹水引流出来以减轻病人的痛苦。常规B超引导下腹腔穿刺引流术，定位不准确，无法对位置较深的病灶以及穿刺间隙较窄或较小的病灶进行穿刺，并且手术成功率低，导致术后并发症多，操作中比较困难；穿刺完成后，引流速度不易掌握和控制，容易给病人造成不适；引流完成后，如果需要注射药物，还得进行二次穿刺，这样不仅给医务人员带来极大的工作难度，而且增大了病人的治疗风险和痛苦，容易造成医疗纠纷。At present, clinically, ascites can be produced when the heart, liver, kidney, etc. have pathological changes. When the intra-abdominal fluid increases by more than 200ml, it can be regarded as a symptom. In clinical practice, while finding the cause and symptomatic treatment, it is also necessary to drain the ascites. Doctors usually perform paracentesis and drainage on patients with ascites to relieve the pain of the patients by draining the ascites. Conventional B-ultrasound-guided abdominal puncture and drainage is inaccurate in positioning, unable to puncture deep lesions and lesions with narrow or small puncture gaps, and the success rate of the operation is low, resulting in many postoperative complications. Difficulty; after the puncture is completed, the drainage speed is not easy to grasp and control, and it is easy to cause discomfort to the patient; after the drainage is completed, if a drug needs to be injected, a second puncture has to be performed, which not only brings great difficulty to the medical staff, but also increases the difficulty of the operation. It increases the risk and pain of the patient's treatment, and it is easy to cause medical disputes.
