背景技术Background technique

腹腔镜技术具有手术视野清晰、解剖层次精确、损伤小、出血少和并发症少等优点，逐渐应用于多个临床学科。后腹腔镜手术能迅速直接进入术野，分离组织少、损伤小、对肠道功能影响小、患者术后恢复快，并克服了因腹腔内既往病史应用的受限，避免了对腹腔的污染和肿瘤种植。但由于腹膜后腔操作空间小、解剖标志不明显、对操作者要求较高，手术难以顺利完成。现有的后腹腔气囊扩张器在临床使用中，需要用注射器一针管一针管充气，不仅操作繁琐，注射针头难以插入进气口，而且手术时间较长，给患者带来了很多痛苦和负担。Laparoscopic technique has the advantages of clear surgical field of view, precise anatomical level, less damage, less bleeding and fewer complications, etc., and has been gradually applied in many clinical disciplines. Retroperitoneal laparoscopic surgery can quickly and directly enter the operation field, with less separated tissue, less damage, less impact on intestinal function, and quick postoperative recovery for patients. It also overcomes the limitation of application due to the past medical history in the abdominal cavity and avoids contamination of the abdominal cavity. and tumor growth. However, due to the small operating space in the retroperitoneal cavity, unobvious anatomical landmarks, and high requirements for the operator, it is difficult to complete the operation smoothly. In the clinical use of the existing retroperitoneal balloon dilator, it is necessary to inflate the syringe with one needle and one needle. Not only is the operation cumbersome, the injection needle is difficult to insert into the air inlet, but also the operation time is long, which brings a lot of pain and burden to the patient.
