Positioning device for pulmonary bulla rupture site

Abstract

The invention provides a positioning device for a pulmonary bulla rupture site. According to the positioning device, a pulmonary alveoli rupture and air leakage site can be positioned quickly and accurately. The positioning device for the pulmonary bulla rupture site comprises an active lighting source, an imaging optical system, a dichroic light splitting prism, a first camera, a second camera, a control computer, a data handling system and a fluorescent material, wherein the first camera and the second camera are arranged on two-way light splitting light ways of the dichroic light splitting prism correspondingly, and the fluorescent material is used being matched with the active lighting source. An observed pulmonary alveoli tissue is under the irradiation of the active lighting source, through the imaging optical system, and through the dichroic light splitting prism, then a visible light wave band is imaged on the target face of the first camera, a fluorescence wave band is imaged on the target face of the second camera, the control computer collects image data of the first camera and the second camera, and the pulmonary alveoli rupture site is marked through the data handling system and displayed in real time on a display of the control computer. The system has a compact structure, a small volume and low cost, and a handheld portable type can be achieved.

Description

technical field [0001] The invention relates to an imaging detection device in the medical field, in particular to an imaging system structure for locating the location of alveolar rupture. Background technique [0002] Bullae secondary to pneumonia or lung abscess are more common in infants, single or multiple. Due to inflammatory lesions, the mucous membrane of the small bronchi is edematous, resulting in partial blockage of the lumen and a valve effect. Air can enter the alveoli and is not easy to be discharged. The pressure in the alveoli increases, and the alveolar septum gradually ruptures due to the increased pressure in the alveoli, forming a huge The air-sac-containing cavity in the lung, which is called bulla clinically, is one of the common emergencies in thoracic surgery. Small bullae themselves do not cause symptoms, and patients with simple bullae often have no symptoms. Some bullae can remain unchanged for many years, and some bullae can gradually increase. ...

AI Technical Summary

Problems solved by technology

Although this method can find the location of alveolar rupture and air leakage, it has disadvantages such as poor timeliness and unintuitiveness, which greatly prolongs the patient's operation time and virtually increases the patient's pain
