TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field, concretely is a novel pericardial puncture device. BACKGROUND
[0002] Pericardium is a kind of connective tissue membrane structure that is tightly wrapped around the heart and has important physiological significance. In the clinical medical context, when acute pericardial hematoma or acute pericardial effusion occurs, it often leads to acute pericardial infarction, a serious condition. In addition, during the operation of external radiofrequency ablation, pericardial puncture is also required as a medical procedure.
[0003] Traditional pericardial puncture devices have some problems in actual use. Especially in the case of excessive pericardial effusion, due to the limited capacity of the needle tube, it is necessary to pull out the needle tube from the needle head multiple times during the liquid extraction process, thereby discharging the liquid extracted from the needle tube, and then reinstalling the needle tube into the needle head to continue the liquid extraction operation. However, this repeated process of pulling out the needle tube and reinstalling it into the needle head is risky. During the operation, even a very slight external force or operational error can cause the needle head to shift position. The shift in needle head position is a very dangerous situation for the ongoing pericardial puncture surgery, as it can lead to inaccurate puncture sites, unnecessary damage to the tissues around the heart, and can also affect the efficiency and effectiveness of the liquid extraction, and even can cause a series of more serious complications, posing a great safety hazard to the smooth progress of the entire operation. SUMMARY
[0004] The purpose of the utility model is to provide a novel pericardial puncture device to solve the problems raised in the background.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: a novel pericardial puncture device, comprising a main body, a needle head stabilizing cover installed on the main body, a hose installed on the needle head stabilizing cover, a connecting device installed at the other end of the hose, a shunt device installed in the connecting device, a rotating column installed in the shunt device, a rotating handle installed on the rotating column, a bottom cover installed below the rotating column, a needle tube installed on the left side of the connecting device, a piston installed in the needle tube, a push rod installed on the piston, a baffle installed on the left side of the push rod, a needle tube stabilizing cover installed on the baffle, and a push head installed on the left side of the needle tube stabilizing cover.
[0006] Preferably, the piston is attached to the needle tube, and when the push rod is pulled, the right side of the piston maintains a constant air pressure.
[0007] Preferably, the baffle ensures that the piston is not pulled out of the needle tube when the push rod pulls the piston.
[0008] Preferably, the rotating column can rotate in the shunt device under the driving of the rotating handle.
[0009] Preferably, the shunt device and the rotating column are both provided with T-shaped channels.
[0010] Compared with the prior art, the utility model has the beneficial effects that:
[0011] 1. The novel pericardial puncture device is constructed in a needle and needle tube separation mode, a hose and a connecting device are additionally arranged between the needle and the needle tube. The connecting device is internally provided with a shunt device. When liquid suction operation is started, the shunt device can normally suck out the effusion in the pericardium. When the effusion in the needle tube is about to be filled, the rotating column in the connecting device is rotated, and then the push rod is pressed, so that the effusion in the needle tube is directly discharged from the effusion discharge port arranged on the side. After the effusion discharge operation is completed, the rotating column is rotated back to the initial position, and the effusion suction operation can be performed again. This mode skillfully removes the steps of pulling out and installing the needle tube from the needle in the traditional pericardial puncture device during effusion suction. By avoiding these operations, the stability of the needle during the whole effusion process is effectively maintained, so that various risks caused by the position deviation of the needle are reduced, such as the risk of mistakenly damaging the tissue around the heart, the risk of reducing the effusion efficiency, and the risk of causing serious complications, and the safety and effectiveness of the pericardial puncture operation are greatly improved.

DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0017] Embodiment: please refer to Figure 1 The utility model provides a technical scheme: a novel pericardial puncture ware, including main part 1, needle head steady cover 2 is installed on main part 1, needle head steady cover 2 is installed with hose 3, the other end of hose 3 is installed with connecting device 4, shunt device 5 is installed in connecting device 4, shunt device 5 is installed with rotating column 7, rotating column 7 is installed with rotating handle 8, the bottom cover 6 is installed below rotating column 7, needle tube 14 is installed in the left side of connecting device, piston 9 is installed in needle tube 14, push rod 10 is installed on piston 9, baffle 11 is installed in the left side of push rod 10, needle tube steady cover 13 is installed on baffle 11, push head 12 is installed in the left side of needle tube steady cover 13.
[0018] Wherein, piston 9 is attached to needle tube 14, when push rod 10 is pulled, the right side of piston 9 keeps constant air pressure.
[0019] In this embodiment, it is ensured that the effusion can be stably extracted when extracting the effusion.
[0020] Wherein, baffle 11 can ensure that piston 9 will not be pulled out of needle tube 14 when push rod 10 pulls piston 9.
[0021] In this embodiment, it is prevented that the effusion will backflow due to air pressure imbalance caused by piston being pulled out when extracting the effusion.
[0022] Wherein, rotating column 7 can rotate in shunt device 5 under the drive of rotating handle 8.
[0023] In this embodiment, it can adjust the extraction state, so that it can be extracted and discharged flexibly.

[0025] In this embodiment, it is ensured that the sealing state after conversion is avoided, and the effusion is prevented from flowing.
[0026] Working principle: after the device is taken out from the sealed bag, the needle needs to be disinfected again to ensure that the needle is always in a sterile state. This disinfection step is very important, because any microbial contamination may cause infection and other adverse consequences.
[0027] After completing the disinfection operation, the needle is accurately inserted into the part where the effusion needs to be extracted by professional operation. Then, pull the push head, at this time, due to the air pressure difference formed on the right side of the piston, the effusion will be extracted into the needle tube under the drive of this pressure.
[0028] When the liquid in the needle tube reaches a certain amount, the rotating column is rotated to change the outflow direction of the liquid.
[0029] After the liquid discharge operation is completed, the rotating column can be rotated again to change back to the original outflow direction, and the liquid extraction work is continued, and the operation is repeated until the liquid is completely extracted.
