Puncture device for cardiothoracic surgery

Abstract

The invention provides a puncture device for the cardiothoracic surgery department, and relates to the technical field of medical instruments. The body is of a rectangular structure. The fixing piece is installed on the top of the supporting piece. A U-shaped bulge on the mounting frame is mounted in a moving groove in the fixing mechanism; the rotating groove is formed in the top end in the mounting frame; the rotating piece is installed in the rotating groove through the cylindrical protrusion at the bottom. A cylindrical bulge at the top of the marking piece is connected with the rotating piece through a spring; by moving the mounting frame, the mounting frame is moved to the position right above the part needing to be punctured, by pressing the marking piece, the marking piece compresses a spring on the rotating piece, the marking piece makes contact with the human body, meanwhile, the rotating piece is adjusted to rotate in the rotating groove, and therefore the marking piece marks the punctured position; the puncture device is simple in structure, convenient to puncture and capable of solving the problem that according to an existing traditional puncture device, a puncture part cannot be marked according to requirements during puncture.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture device for thoracic and cardiac surgery. Background technique [0002] Cardiothoracic surgery mainly treats heart disease by surgery, and the common heart diseases treated are: congenital heart disease, valvular heart disease, coronary heart disease, thoracic aortic aneurysm, pericardial disease, heart tumor, etc. In other diseases, the patient needs to be drained by puncture and drainage, and this device needs to be used at this time; however, as far as the current traditional puncture device is concerned, the puncture site cannot be marked as required during puncture, preventing When a puncture error occurs, the depth of the puncture inside the human body cannot be controlled, and when the existing puncture device is in use, if the needle is blocked during drainage, it cannot be automatically dredged, and cannot be used to assist in the extraction of effu...

AI Technical Summary

Problems solved by technology

[0002] Cardiothoracic surgery mainly treats heart diseases with surgery, and the common heart diseases treated include: congenital heart disease, valvular heart disease, coronary heart disease, thoracic aortic aneurysm, pericardial disease, heart tumor, etc., in the treatment of pleural effusion In diseases such as puncture and drainage, the patient needs to be drained, and this device is needed at this time; however, as far as the current traditional puncture device is concerned, it is impossible to mark the puncture site according to the demand during puncture, so as to prevent In the case of puncture errors, it is impossible to control the depth of puncture inside the human body, and when the existing puncture device is in use, if the needle is blocked during drainage, it cannot be automatically dredged, and it cannot be used to assist in the extraction of effusion The effect of pressing can't better extract the effusion
