Embodiment 1
[0017] A lung puncture biopsy method capable of closing the pleural cavity, the method comprising the steps of:
[0018] (1) The lung puncture needle is a double-chamber needle with a beveled needle tip and a thin lumen on the tip side. The thin lumen head is connected with a flexible hose. In order to avoid affecting the operation of the biopsy needle through the biopsy cavity, the flexible hose can be connected to a syringe for injection of biological glue , the other cavity is thicker as the biopsy cavity, and in the standby state, the inner trocar is placed in the biopsy cavity.
[0019] (2) Hold a puncture needle to puncture the skin from the positioning point, and enter the surface of the pleural cavity under the monitoring of color Doppler ultrasound or CT.
[0020] (3) Use the injection syringe to connect the hose to inject bio-glue. The bio-glue is Compaite medical glue. The bio-glue can solidify within 5-15 seconds and quickly play the role of adhesion and sealing of...
Embodiment 2
[0023] According to a kind of lung puncture biopsy method that can close the pleural cavity described in Example 1, the corresponding animal experiment verification was carried out, and the process is as follows:
[0024] 1) Experimental animals exempt from New Zealand.
[0025] 2) Take the right lung as the experimental side and the left lung as the control side.
[0026] 3) Experimental side: under CT monitoring, after hair removal, numbness, and routine disinfection, mark the puncture site with a marker pen. After inserting the needle with a 5ml syringe to the junction of the pleura and the lung, inject 0.5ml of biological glue (Kangpaiwu). One minute after the biogel was solidified, a 12G biopsy needle was inserted into the lung along the original puncture point under CT monitoring.
[0027] 4) Control side: At the same time, under CT monitoring, inject a needle into the lung with a 5ml syringe.
[0028] 5) Intraoperative CT monitoring. Thirty minutes after the operati...
