Preferably, a tube plug is arranged in the branch tube, a traction ring is arranged on the outer wall of the tube plug, and the tube plug can be taken down through the traction ring to extract pericardial effusion in the needle cylinder when the device is used.

The outer diameter of the traction ring is larger than the inner diameter of the branch pipe, so that the pipe plug is prevented from being sucked into the needle cylinder when the push-pull rod pulls the piston.

Further, a positioning hole is formed in the center of the positioning disc, and the positioning hole is formed right below the puncture needle.

Preferably, the elastic mesh enclosure is made of rubber material.

The utility model adopts the structure to obtain the beneficial effects as follows: the intracardiac puncture device provided by the utility model is simple to operate, compact in structure and reasonable in design, and the positioning holes of the positioning disc are abutted against the puncture part of a patient, so that the problem of positioning deviation in the puncture process is avoided, and unnecessary pain to the patient is reduced; the elastic mesh enclosure made of rubber is pressed and deformed in the puncturing process, so that rigid interference to doctors is avoided; the traction ring avoids the phenomenon that the pipe plug is sucked into the needle cylinder when the push-pull rod pulls the piston, and the pericardial effusion in the needle cylinder can be extracted and discharged after the pipe plug is taken down by the traction ring, so that the frequency of the puncture needle entering a human body is reduced, the working intensity of doctors is reduced, and the puncture liquid discharging efficiency is improved.
