Problems solved by technology

[0003] Existing puncture needles are difficult to accurately grasp the puncture depth, and it is often necessary to insert and withdraw the syringe multiple times until the liquid is drawn out, which often requires at least two people to operate
In addition, when the fluid in the pleural cavity is pumped less and less, the visceral pleura is getting closer to the parietal pleura. If the op

Abstract

The invention discloses a puncture device for the thoracic surgery department. The puncture device comprises a needle body, an injection hole formed in the needle body and a liquid suction cavity formed in the needle body; a liquid suction tube is arranged in the liquid suction cavity, the needle body is provided with a fixing plate, and the fixing plate is provided with a liquid suction connecting head connected with the liquid suction tube; the needle body is provided with an injection mechanism, the injection mechanism comprises a syringe connected with the needle body, the syringe is provided with a liquid suction syringe, and the liquid suction syringe is connected with the liquid suction connecting head. The puncture device can be used for conducting puncture and sucking liquid in one time and injecting medicine, one person can operate the device, and the injection and liquid suction effects are good.

Description

Technical field [0001] The invention relates to the technical field of thoracic cavity-related medical puncture instruments, in particular to a puncture device for thoracic surgery. Background technique [0002] The purpose of thoracentesis is to make a clear diagnosis and reduce the pressure on internal organs. The main steps are: (1) Place a needle at the selected puncture point for local anesthesia; (2) Check whether the puncture needle is unobstructed and prepare for puncture; (3) The surgeon performs puncture at the puncture point and slowly inserts the needle during the puncture. When the needle is inserted to the depth indicated by the B-ultrasonic positioning, try to withdraw it. If the liquid is drawn out, continue to insert the needle appropriately. If there is liquid drawn out, stop and continue. Insert the needle and suck the liquid in the chest cavity with the assistance of the assistant to complete the puncture; (4) When the puncture needs to be injected into the ch...
