Adjustable pleural and peritoneal cavity puncture needle

Abstract

The invention discloses an adjustable pleural and peritoneal cavity puncture needle which comprises a needle core nozzle, a needle core rod, a needle core seat, a needle tube nozzle, a needle tube rod, a needle tube seat, a cylinder screw and nut, a rubber plastic mat, a rubber pipe, a base plate and the like. The adjustable pleural and peritoneal cavity puncture needle is characterized in that the needle is blunt and sharp in a changeable manner, namely, the needle tube nozzle is blunt, organs in a cavity cannot be punctured, the needle core nozzle is sharp, and a needle tube with the blunt nozzle punctures the cavity, performs suction, irrigation and drainage and then exits from a needle core through the rubber pipe connected with the needle tube seat. According to the depth of dropsy or pneumothorax and a body surface, the cylinder screw and nut and the rubber plastic mat are used for continuously adjusting the depth of the needle tube to perform operation. By the aid of the base plate, a body position is changed, so that the puncture needle is positioned at the lowest portion of the dropsy, and residual liquid is completely drained. Tube insertion for apocenosis can be performed without surgical cutting, operation is simple, convenient, safe and reliable, and the puncture needle is suitable for puncture, suction, irrigation, drainage, assisted diagnosis and treatment in various medical units.

Description

technical field [0001] The invention relates to a puncture needle for thoracic and peritoneal cavity, in particular to an adjustable puncture needle for thoracic and peritoneal cavity. Background technique [0002] So far, there are two types of thoracentesis: one is the traditional puncture needle, which is sharp and has the potential danger of puncturing lung tissue when it enters the pleural cavity, especially when closed drainage is used; the other is "Catheter pack", after needle puncture, the "catheter pack" sends the slender flexible catheter into the chest or peritoneal cavity through the needle tube. When the drainage time is too long or the liquid is too thick, there is often the disadvantage of blockage, and repeated punctures are required. Surgical drainage was created. Peritoneal puncture cannot solve some common acute abdominal diseases, such as simple gastric and duodenal ulcer with perforation, acute suppurative appendicitis with perforation, acute necrotizi...

[0002] So far, there are two types of thoracentesis: one is the traditional puncture needle, which is sharp and has the potential danger of puncturing lung tissue when it enters the pleural cavity, especially when closed drainage is used; the other is "Catheter pack", after needle puncture, the "catheter pack" sends the slender flexible catheter into the chest or peritoneal cavity through the needle tube. When the drainage time is too long or the liquid is too thick, there is often the disadvantage of blockage, and repeated punctures are required. Surgical catheterization and drainage

Peritoneal puncture cannot solve some common acute abdominal diseases, such as simple gastric and duodenal ulcer with perforation, acute suppurative appendicitis with perforation, acute necrotizing pancreatitis with peritonitis, liver abscess and other diseases. With satisfactory drainage, surgery is difficult to avoid

[0003] The current chest, abdomen, and liver puncture devices are difficult to remove all the fluid in the patient's body by suction and drainage once or even multiple times, mainly because of the blockage during drainage and the failure of the suction and drainage devices to touch the residual fluid in the patient. Fluid in the lower part of the body
