However, although a customized chest tube based on images of the pleural cavity may avoid any puncture of a collapsed lung, and / or image-based insertion of a chest tube may avoid any puncture of a collapsed lung, the collapsed lung condition may suddenly Occurs rapidly and without warning and must be corrected quickly to allow the patient to breathe properly

Embodiment Construction

[0018] The premise of the present invention is a standardized set of cannulae with a fixed orientation as the cannula(s) extend in the direction of the target location within the patient's pleural cavity. Fixed orientation is particularly important in the context of cannulae having a longitudinal non-zero curvature (eg arc) along a portion or the entirety of the cannula. In order to facilitate the understanding of the present invention, this paper will be in the port establishment stage of the collapsed lung treatment method of the present invention ( Figure 7 ) and the fluid uptake phase ( Figure 8 ) describes an exemplary set of surgical tools for treating a collapsed lung condition in the context of ( Figure 2-6 ).

[0019] Specifically, the surgical tool set uses a trocar 20 ( figure 2 ) and includes pleural port tubing 30 ( image 3 ), target orientation tube 40 ( Figure 4 ) and fluid pickup tube 50 ( Figure 5 ) of the nested cannula. These tubes are fabricat...

Abstract

A surgical kit for treating a collapsed lung condition employs a trocar (20) and a nested cannula including a pleural port tube (30) and a fluid aspiration tube (50). In operation, the trocar (20) is nested within the pleural port tube (30) and the port is pierced into the patient's pleural cavity (10) with the trocar (20) while the pleural port tube ( 30) Fastened in this port. After removal of the trocar (20) from the pleural port tube (30), fluid aspiration is advanced in a fixed orientation via the secured pleural port tube (30) in the direction of the target site (15) in the pleural cavity (10) Tube (50), and air is drawn from the pleural air space into fluid suction tube (50) via one or more perforations. The fluid intake tube (50) may have a target orientation segment (42), or an additional target orientation tube (40) may be used to fix the orientation of the fluid intake tube (50) relative to the pleural port tube (30).

Description

technical field [0001] The present invention generally relates to nested cannula designs for patients experiencing lung collapse, usually caused by air, blood or fluid in the pleural cavity. In particular, the present invention relates to standardized cannula sets employing fluid intake tubes having a fixed orientation relative to the pleural port tubes to access targeted locations within the patient's pleural cavity to facilitate proper removal of air, blood or other fluids , allowing the lungs to re-expand. Background technique [0002] Under normal conditions, the pleural space surrounding the lungs has a lower pressure than the pressure inside the lungs. Similar to vacuum pressure, the lower pressure in the pleural cavity pulls the lung surface against the chest wall. As the chest and ribs expand, vacuum pressure in the pleural cavity increases, pulling the lung surface outward. This in turn dilates the lung trachea and alveoli. The reverse process occurs during exha...
