Improved pleuroperitoneal cavity puncture needle

Abstract

The invention relates to an improved pleuroperitoneal cavity puncture needle. The puncture needle comprises a steel needle, an isolation plug is arranged at one end of the steel needle; an adjusting section is arranged at one end of the isolating plug; limiting protrusions are arranged on two sides of the adjusting section; an adjusting ring is arranged on the outer peripheral surface of the adjusting section; a limiting groove is formed in the inner wall of the adjusting ring; the limiting groove is matched with the limiting bulges; a fixing sheet is arranged on the adjusting ring; the periphery of the steel needle is sleeved with a hose; and the outer side wall of the steel needle is attached to the inner side wall of the hose. The improved pleuroperitoneal cavity puncture needle has theadvantages of effectively reducing puncture injuries, having good comfort degree, and being convenient to fix and adjust puncture length. The whole process can be completed by only one medical worker, so that time and labor are saved. The improved pleuroperitoneal cavity puncture needle can serve as a novel puncture and drainage tool and has a wide application prospect in clinical popularization.

Description

technical field [0001] The invention relates to the technical field of puncture needles, in particular to an improved thoracoabdominal cavity puncture needle. Background technique [0002] Clinically, thoracoperitoneal catheterization is often used for the treatment of complications such as cancerous pleural effusion, inflammatory pleural effusion, cirrhotic ascites, pleural abscess, intestinal fistula, pancreatic fistula, and biliary fistula in various advanced tumors. Effective and adequate drainage can effectively alleviate the condition and save the patient's life. Therefore, thoracentesis is also one of the most basic operations for clinicians. [0003] However, there are the following defects and deficiencies in the actual application of thoracentesis in the prior art: [0004] First of all, there is effusion in the chest cavity or abdominal cavity. The traditional method is to use a steel needle. The steel needle is very long and is a continuous needle. After enteri...
