The invention discloses a puncture outfit for preventing internal organs of a thoracic cavity from being punctured, which comprises an outer tube and a needle rod arranged in the outer tube, and the outer tube is also provided with a needle rod retraction mechanism, a moving mechanism and a clamping and limiting mechanism; and the near end of the needle rod is provided with a pricking needle with a knife and is exposed out of the end of the outer tube, the needle rod retraction mechanism is arranged at the far end of the needle rod, the movable mechanism abuts against the upper portion of the needle rod retraction mechanism, and the clamping and limiting mechanism is clamped and limited to the movable mechanism. According to the puncture outfit, in the puncture process, due to the pressure of intercostal weaving resistance, the needle rod retraction mechanism and the movable mechanism move relatively, in the moving process, the clamping and limiting mechanism relieves the limitation to the movable mechanism, the movable mechanism relieves the limitation to the needle rod retraction mechanism, and then the needle rod retraction mechanism drives the needle rod to retract into the outer pipe; and the situation that after the needle rod punctures the thoracic cavity, internal organs are punctured due to the fact that force is not well mastered, and operation safety is affected is avoided.
Description
technical field [0001] The invention relates to the technical field of thoracocentesis, in particular to a puncture device capable of preventing internal organs from being stabbed. Background technique [0002] Thoracentesis refers to the operation of entering the pleural cavity with a sterilized acupuncture instrument through the skin, intercostal tissue, and parietal pleura. In the clinical work of thoracic department, thoracentesis is a relatively common, convenient and simple method of diagnosis and treatment. If there is effusion in the patient's pleural cavity through examination, the fluid can be extracted through thoracentesis, and various examinations can be performed to find the cause of the disease; The oppression of internal organs achieves the purpose of treatment. However, the existing thoracentesis needle is easy to damage human tissue after puncture, which affects the safety of the operation. Contents of the invention [0003] The object of the present i...
