  • Development and Design of a New Sonography Rigid Bronchoscopy and Corollary Vacuum-assisted Biopsy Device System

    The present study was to develop and design a new sonography rigid bronchoscopy and corollary vacuum-assisted 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 endobronchial sonography rigid bronchoscopy and matched vacuum-assisted 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.
