Minimally invasive pneumothorax drainage tube

Abstract

The invention relates to a minimally invasive pneumothorax drainage tube, which comprises a hollow tube body and a puncture guide core penetrating through the hollow tube body. A top hole is arranged at one end of the hollow tube body and used for allowing the tip of the puncture guide core to penetrate through and performing drainage, a plurality of side drainage holes are arranged on the tube wall close to the top hole of the hollow tube body, a conical joint is arranged at the other end of the hollow tube body and used for allowing the tail end of the puncture guide core to penetrate through and externally connecting a drainage device, and a spiral anti-folding steel wire is arranged in the tube wall between the top hole and the conical joint of the hollow tube body. The pneumothorax drainage tube has the advantages that by means of puncture guide of the edge-free guide core, a catheter can be easily led into a thoracic cavity for drainage under the condition of eliminating the hidden danger of organ injury, so that pneumothorax symptoms of a patient can be rapidly relieved, the pain of the patient is minimized, and further operation is facilitated for medical workers.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable, minimally invasive and anti-bending pneumothorax drainage tube. Background technique [0002] As we all know, the pleural cavity is composed of pleural parietal and visceral layers, and is a closed potential cavity without air. A rupture of the pleura from any cause, allowing air to enter the pleural space, is commonly referred to as a pneumothorax. When pneumothorax occurs, the pressure in the pleural cavity increases, and even the negative pressure becomes positive pressure, which will compress the lungs and block the venous return to the heart, resulting in varying degrees of pulmonary and cardiac dysfunction. According to the causes of pneumothorax, it can generally be divided into the following categories: artificially injecting filtered air into the pleural cavity to identify intrathoracic diseases under X-ray, which is called artificial pneumothorax; caused by chest traum...

Problems solved by technology

Because the above-mentioned methods have large skin incisions, and need to use large sleeves or hemostats to expand the pectoral muscles, so as to facilitate the insertion of the catheter, they will cause greater pain to the patient during clinical operations, and the patient will suffer from pain. screaming or twisting, which inevitably increases the difficulty of the doctor's operation
