Plier-clamping type pericardiocentesis device

Abstract

The invention relates to a plier-clamping type pericardiocentesis device. The plier-clamping type pericardiocentesis device comprises a plier body, wherein the inner part of the plier body is hollow and a plier transmission mechanism is arranged at the inner part; one end of the plier transmission mechanism is connected with a plier opening in the front end of the plier body; when the plier opening is closed, a puncturing needle hole channel is formed in the middle part or in the periphery; the other end of the plier transmission mechanism penetrates out from the rear end of the plier body andis connected with a traction operating part; a puncturing needle inserting hole which communicates with the inner part of the plier body is formed in one side of the rear end of the plier body; and apuncturing needle is inserted from the puncturing needle inserting hole, and penetrates out from the puncturing needle hole channel in the plier opening. The plier-clamping type pericardiocentesis device disclosed by the invention is simple in structure, pericardium can be seized with a plier device, and lacuna between the pericardium and the epicardium is forced to draw to provide a relative safe puncturing gap, so that dry paracentesis pericardii can be safely performed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a clip-type pericardial puncture device. Background technique [0002] Pericardiocentesis is a diagnosis and treatment technique that directly punctures the pericardial cavity with the help of a puncture needle. It is a common surgical operation in clinic. It is of great significance in the emergency treatment of patients with cardiac tamponade, patients with a large amount of pericardial effusion, and epicardial ablation during cardiac electrophysiological examination. significance. At present, the commonly used method of pericardiocentesis is to puncture the pericardium with a puncture needle percutaneously into the pericardial cavity after the word is accurately positioned, and then insert a guide wire and then place a tube.

Problems solved by technology

At present, the commonly used method of pericardiocentesis is to puncture the pericardium with a puncture needle percutaneously into the pericardial cavity after the word is accurately positioned, and then insert a guide wire and then place a tube. The operation procedure is not complicated, but there are particularities in the anatomical structure. Adhere to the epicardium, and the coronary artery runs on the epicardium, which is easy to damage the coronary artery and cause bleeding; second, it is easy to penetrate the myocardium, causing damage to the internal structure of the heart, and even damage the pulmonary artery and aorta; third, the heart is adjacent to the lungs , Inaccurate puncture can lead to lung damage and cause pneumothorax; 4. It has been reported that pericardial puncture can cause damage to the liver, nearby organs, and blood vessels, etc.

[0003] In summary, pericardiocentesis is a highly dangerous surgical operation, which requires a high level of skill of the surgeon, otherwise it is easy to have complications such as cardiac perforation, pneumothorax, etc., which can lead to the death of the patient in severe cases

[0004] In the process of pericardium puncture, the greatest danger lies in the link of penetrating the pericardium and entering the pericardial cavity. In this link, the greatest danger lies in the small gap between the pericardium and the epicardium, and the puncture needle is easily damaged. Coronary arteries, or penetrating the myocardium, when the amount of pericardial effusion is large, the puncture needle has ample advance and retreat stroke due to the wide gap, and the puncture is relatively safe at this time

However, when the amount of effusion is small, the gap is too small, or the pericardium is dry, the puncture needle is likely to cause damage. Therefore, it is necessary to use a special instrument forceps to pull the gap between the pericardium and the epicardium. Create a safe puncture area, making pericardiocentesis safer and more reliable
