A thoracentesis guiding and positioning device for respiratory department

Abstract

The invention discloses a thoracentesis guiding and positioning device for respiratory department, specifically relates to the field of medical equipment, comprising a main body plate and a connecting plate, the four corners of the main body plate and the connecting plate are fixedly connected with support frames, and the center of the connecting plate runs through A piercing piece is provided, and a positioning piece is provided on the outside of the piercing piece. An adjustment rod is provided between the top of the piercing piece and the main body plate. The positioning piece includes a contact plate, and a fixing ring is provided on 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 one side of the fixing ring. The present invention defines the protruding length of the puncture needle of the puncture member through the positioning member, passes the puncture needle through the second through hole, observes the value of the second scale mark through a magnifying glass, and determines that the length of the puncture needle protruding from the contact plate matches the required puncture depth The value can be accurately matched with the detected puncture depth value, and the puncture depth can be accurately controlled to ensure the one-time success rate of puncture surgery.

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...

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, during the application process, sometimes the puncture depth is insufficient due to inaccurate control of the puncture depth or other reasons, and a second puncture depth is required, or the puncture depth is too deep to affect the normal puncture effect, which increases the medical staff. Difficult to operate, will increase the pain of the patient
