Ultrasonic microscopic examination system for mediastinal lesions

Abstract

The invention belongs to the field of medical apparatus and instruments, and particularly relates to an ultrasonic microscopic examination system for mediastinal lesions. The ultrasonic microscopic examination system comprises an ultrasonic rigid bronchoscope and a vacuum aspiration biopsy instrument. The ultrasonic rigid bronchoscope comprises an improved rigid bronchoscope, a catheter type ultrasonic probe, a cold light source main unit, a photographic main unit and an ultrasonic main unit; the rigid bronchoscope comprises an endoscope body and a slim operating end, and the catheter type ultrasonic probe is mounted at the head of the operating end; the endoscope body is connected with a light source by a light source interface; the cold light source main unit is connected with the photographic main unit; the catheter type ultrasonic probe is connected to the ultrasonic main unit; the vacuum aspiration biopsy instrument comprises a power control main unit of a vacuum aspiration pump system and a puncture biopsy needle. The ultrasonic microscopic examination system has the advantages that the ultrasonic microscopic examination system can be easily and conveniently operated when the mediastinal lesions are diagnosed and treated by doctors, the diagnosis accuracy can be improved, the false negative rate can be reduced, the occurrence rate of infective complications can be decreased, the operative time can be shortened, and accordingly economic burden on patients and suffering of the patients can be relieved.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an ultrasonic microscopy system for mediastinal lesions. Background technique [0002] Because of the particularity of the anatomical structure of the mediastinum, the diagnosis of mediastinal lesions is a difficult point in clinical work. At present, bronchial fiberoptic needle aspiration biopsy (TBNA) has been carried out abroad, but TBNA only conducts unguided "blind puncture" based on preoperative imaging information, and there are still some serious complications such as pneumothorax, bleeding, and mediastinal emphysema. Dangerous, and because the working end is soft, effective operation cannot be performed, which may easily lead to missed diagnosis and incomplete operation. [0003] Rigid bronchoscope, also known as "ventilated bronchoscope" because it can keep the airway unobstructed during operation, has been used clinically for more than 100 years. With the a...
