技术领域technical field
本实用新型涉及临床医学的辅助设备，具体地指一种便于引导定位的组合式支气管封堵器。The utility model relates to auxiliary equipment for clinical medicine, in particular to a combined bronchial occluder which is convenient for guiding and positioning.
背景技术Background technique
利用支气管封堵器进行单侧肺部支气管填塞是胸外科手术中一种常用的实现单肺通气的方法，特别在小儿或者困难气道等特殊患者的处理中，该方法优势更为明显。Unilateral pulmonary bronchial tamponade using a bronchial occluder is a commonly used method to achieve one-lung ventilation in thoracic surgery, especially in the treatment of special patients such as children or difficult airways, and the advantages of this method are more obvious.
通常，支气管封堵器以内置在气管导管内的方式进入患者体内，但是该方式在术中存在以下问题：1、支气管封堵器内置在气管导管内占据了气管导管内部的不少空间，减少了有效通气的面积；2、气管导管还内置有纤维支气管镜，在利用纤维支气管镜对位时，支气管封堵器与纤维支气管镜同时位于同一导管内，不容易调节堵塞器的位置。近年来研究表明采用经气管导管外置入支气管封堵器具有明显的优势，易于采用纤支镜对位，并且不影响通气面积。Usually, the bronchial occluder is inserted into the patient's body by being built into the tracheal tube, but this method has the following problems during the operation: 1. The bronchial occluder is built into the tracheal tube and occupies a lot of space inside the tracheal tube, reducing the 2. The endotracheal tube also has a built-in fiberoptic bronchoscope. When the fiberoptic bronchoscope is used for alignment, the bronchial occluder and the fiberoptic bronchoscope are located in the same catheter at the same time, and it is not easy to adjust the position of the occluder. Studies in recent years have shown that the bronchial occluder placed outside the tracheal tube has obvious advantages, and it is easy to align with the fiberoptic bronchoscope without affecting the ventilation area.
但是临床上由于一部分病人采用普通喉镜插管时，声门显露不良，导致气管导管外置入支气管封堵器非常困难，因此，需要利用到Airtraq、Pentax AWS、King vision等视频喉镜。Airtraq喉镜是一种可视喉镜，采用人体解剖学设计，喉镜的前端角度与正常人体咽喉部的解剖角度一致，插管时不需要口、咽和喉三轴线重合就可以清楚地看到声门。Airtraq喉镜目前已经广泛使用于临床麻醉，特别是普通喉镜显露困难的病人具有明显的优势。Airtraq喉镜的镜片右侧有一个引导槽，可用于放置气管导管和支气管封堵器，在利用Airtraq视频喉镜置入支气管封堵器的过程中，由于支气管封堵器细长，而Airtraq视频喉镜引导槽比较宽，置入支气管封堵器不好着力，同时难以调整方向。However, clinically, when some patients are intubated with ordinary laryngoscope, the glottis is not well exposed, which makes it very difficult to insert a bronchial occluder outside the endotracheal tube. Therefore, video laryngoscopes such as Airtraq, Pentax AWS, and King vision need to be used. Airtraq laryngoscope is a visual laryngoscope, which is designed according to human anatomy. The angle of the front end of the laryngoscope is consistent with the anatomical angle of the throat of a normal human body. It can be clearly seen without the coincidence of the three axes of the mouth, pharynx and larynx during intubation. to the glottis. Airtraq laryngoscope has been widely used in clinical anesthesia, especially for patients who are difficult to reveal by ordinary laryngoscope. There is a guide groove on the right side of the lens of the Airtraq laryngoscope, which can be used to place the tracheal tube and the bronchial occluder. During the process of using the Airtraq video laryngoscope to place the bronchial occluder, because the bronchial occluder is slender, the Airtraq video The guide groove of the laryngoscope is relatively wide, and it is not easy to place the bronchial occluder with force, and it is difficult to adjust the direction at the same time.
