Problems solved by technology

[0004] Existing thoracentesis devices mostly use manual puncture or auxiliary positioning devices to perform puncture operations. However, in the actual operation process, due to the different thickness of the patient's fat layer and the selection of puncture positions, it is necessary to manually adjust the puncture depth. However, duri...

Abstract

The invention discloses a chest puncture guiding and positioning device for respiratory department, and particularly relates to the field of medical appliances. The device comprises a main body plateand a connecting plate; supporting frames are fixedly connected at four corners of the main body plate and four corners of the connecting plate; a puncture piece penetrates through the center of the connecting plate; a positioning piece is arranged outside the puncture piece; an adjusting rod is arranged between the top end of the puncture piece and the main body plate; the positioning piece comprises a contact plate; a fixing ring is arranged at the top of the contact plate; a fixing frame is arranged between the fixing ring and the contact plate; and a second fixing button is arranged on oneside of the fixing ring. According to the invention, the positioning piece is used for limiting the protruding length of a puncture needle of the puncture piece, the puncture needle passes through the second through hole, the numerical value of a second scale mark is observed through a magnifier, and the matching value of the length of the puncture needle extending out of the contact plate and arequired puncture depth is determined, so that the detected puncture depth value can be matched accurately, the puncture depth can be accurately controlled, and the one-time success rate of a punctureoperation is ensured.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, the invention relates to a thoracentesis guiding and positioning device for respiratory department. Background technique [0002] Thoracentesis refers to the operation of entering the pleural cavity with a sterile needle through the skin, intercostal tissue, and parietal pleura. In the clinical work of the pulmonary department, thoracentesis is a relatively common, convenient and simple method of diagnosis and treatment. If through the examination, it is found that there is fluid in the patient's pleural cavity, the fluid can be extracted through thoracentesis, and various examinations can be performed to find the cause of the disease. [0003] In the clinical work of the pulmonary department, thoracentesis is a relatively common, convenient and simple method of diagnosis and treatment. For example: Through inspection, we found that there is effusion in the pa...
