摘要
研制一种损伤小、并发症少的新型超声硬质支气管镜及配套活检系统,减少损伤及并发症的发生,缩短检查时间,减轻患者痛苦。将超声领域的新技术——导管式超声探头与改良后的硬质支气管镜相结合,同时设计了与之配套的以真空抽吸和旋转切割为基本原理的真空抽吸活检仪,完成病变组织的定位、真空抽吸穿刺活检及标本收集。改良了原有的硬质支气管镜,减轻痛苦,减少并发症;导管式超声探头可获得清晰的超声图像,明确病变组织及血管的位置,避免穿刺时损伤血管,降低并发症的发生率;真空抽吸活检仪具有独特的真空抽吸旋切动力系统及活检针后置的组织收集仓,真空抽吸及旋转切割下的组织可从组织收集仓取出,无需反复拔插穿刺针,快速获得足量的组织标本,提高诊断的准确率。该系统将改良后的硬质支气管镜与导管式超声探头相结合,使硬镜操作范围延伸到气管壁外,为纵隔疾病的诊断及治疗提供了一个新的平台。
The present study was to develop and design a new sonography rigid bronchoscopy and corollary vacuumassisted biopsy device system with less injury and complication. The system combined ultrasonic-probe with ultrasound catheter, a new medical ultrasound technique, and rigid bronchoscopy （RB） which is improved with an auxiliary vacuum-assisted biopsy device. The principle of the device is vacuum suction and rotary knife. The reduced outer diameter of the RB led to less pain and lower complications for the patient. With the help of ultrasonic-probe （30 MHz）, lesions and blood vessels can be identified clearly and unintentional puncture and damage to blood vessels can be avoided. Plenty of lesions can be obtained quickly through the vacuum-assisted biopsy device without getting puncture needle in and out repeatedly. The novel endobronehial sonography rigid bronchoscopy and matched vacuumassisted biopsy device has many remarkable advantages. It can enlarge the applied range of the RB from endobronchial to mediastinal lesions, avoiding unintentional puncture of vessels. Obtaining multiple samples with a higher accuracy rate than that by other sampling techniques, minimizing operation time, alleviating pain and decreasing the complication rate, the system makes up the technical deficiency for the diagnosis and treatment of the mediastinal lesions, to a certain degree.
