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...

Abstract

The invention discloses a lung puncture biopsy method for a closable pleural cavity. The lung puncture biopsy method comprises the following steps that (1) a double-cavity needle serves as a lung puncture needle, the needle tip is a bevel, the tip end side is a thin cavity, the head end of the thin cavity is connected with a hose, in order to avoid operation of a biopsy needle through a biopsy cavity, the hose is arranged to be connected with an injector for injecting biological adhesive, the other cavity is thick and serves as the biopsy cavity, and under a standby state, an inner sleeve needle is arranged in the biopsy cavity; (2) the puncture needle is held to puncture skin from a position point and enter the surface of the pleural cavity under monitoring of color ultrasound or CT; (3)an injecting syringe is connected with the hose to inject the biological adhesive which is Compont medical adhesive, the biological adhesive can be solidified within 5-15 seconds, and thus the effectthat the pleural cavity is sealed in an adhesion mode is achieved quickly; and (4) the puncture needle is held to continuously enter a lung tissue, when the situation that the puncture needle enters apulmonary lesion is seen through the color ultrasound or CT, an inner sheath needle is quit, and the puncture biopsy needle is placed to obtain a sample. The incidence rate of pneumothorax is significantly decreased through the lung puncture biopsy method.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a lung puncture biopsy method capable of closing the pleural cavity. Background technique [0002] The biopsy needles currently used for lung puncture are likely to cause pneumothorax, which leads to puncture failure and even threatens the life safety of patients. The pleural cavity is a cavity formed by the parietal pleura and the visceral pleura. Under normal physiological conditions, the pleural cavity does not contain air. A pneumothorax occurs when air enters the chest cavity. The cause of pneumothorax is the damage caused when the puncture needle passes through the visceral pleura during the puncture, so that the air in the lung enters the pleural cavity along the hole formed by the puncture. Because the pleural cavity is bound to be damaged during lung puncture, the incidence of pneumothorax caused by lung puncture is very high. The present invention is an innovation ...
