Problems solved by technology

[0002] Thoracentesis and drainage is a commonly used operation in clinical practice. The currently used instruments are mainly thoracentesis needles and one-way drainage devices. During the operation, it is necessary to use positioning aids to determine the puncture depth and orientation of the puncture and drainage needle. The requirement for accuracy is very high, therefore, the positioning of the thoracentesis drainage needle is particularly important. The positioning accuracy of the existing thoracentesis drainage needle is low, and the needle body is prone to vibration during the puncture process. Therefore, the existing thoracentesis drainage needle needs to be adjusted. Drain Needle Improvement

Abstract

The invention discloses a side-opening thoracic puncture and drainage needle, which comprises a needle body which is integrally molded by a medical stainless steel material, wherein a connecting and locating part is arranged at the upper part of the needle body; a needle rod is arranged at the lower part of the needle body; a needle tip is arranged at the lower end of the needle rod; the needle tip is of a conical structure; the connecting and locating part comprises a clamping part at the upper end, a rod part in the middle and a baffle plate which is arranged at the lower end of the rod part; a concave ring is arranged in the middle of the rod part; the clamping part comprises a cylindrical part which is arranged at the upper part and a shrinking neck part which is arranged at the lower part; and non-slip patterns are distributed on the outer wall of the cylindrical part.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a side-opening chest drainage puncture needle. Background technique [0002] Thoracentesis and drainage is a commonly used operation in clinical practice. The currently used instruments are mainly thoracentesis needles and one-way drainage devices. During the operation, it is necessary to use positioning aids to determine the puncture depth and orientation of the puncture and drainage needle. The requirement for accuracy is very high, therefore, the positioning of the thoracentesis drainage needle is particularly important. The positioning accuracy of the existing thoracentesis drainage needle is low, and the needle body is prone to vibration during the puncture process. Therefore, the existing thoracentesis drainage needle needs to be adjusted. The drainage needle was improved. Contents of the invention [0003] The purpose of the present invention is to provide a side-open...
