Abstract

The invention relates to the technical field of surgical devices, and discloses an exhaust device for cardiac surgery, which solves the problems that the length of a fixing band is inconvenient to adjust according to actual requirements and certain limitation exists, and comprises a main body, a pipeline base, an exhaust tube, a needle head and a fixing band, and the pipeline base is connected with the main body through the exhaust tube; the needle head is arranged at the bottom of the pipeline base, a fixing seat is arranged on one side of the pipeline base, the fixing seat and the pipeline base are connected through two connecting plates, a first rectangular hole is formed in one side of the fixing seat, one end of the fixing belt is fixedly connected with one side of the pipeline base, and the other end of the fixing belt penetrates through the first rectangular hole. A second rectangular hole is formed in the inner wall of the top of the first rectangular hole, a clamping plate is arranged in the second rectangular hole, an adjusting plate is arranged above the clamping plate, and the clamping plate and the adjusting plate are connected through an elastic unit; the length of the fixing belt can be adjusted, and the fixing belt pressing force of the clamping plate can be adjusted conveniently.

Description

technical field [0001] The invention belongs to the technical field of surgical devices, in particular to an exhaust device for heart surgery. Background technique [0002] The exhaust device for cardiac surgery is mainly used to discharge the gas in the blood vessels during the cardiac surgery, so as to prevent gas embolism during and after the operation. During the use of the existing exhaust device for cardiac surgery, the connection between the device and the patient is formed by wrapping the fixing belt around the patient, and the delivery of the exhaust needle is made more stable. After retrieval, the announcement number is CN212756637U is a kind of exhaust device for cardiac surgery, through the designed movable block, connecting plate, fixed groove, after the groove is engaged with the block, then the structure is limited, and the original basis is used The engagement between the connecting block and the connecting block is more stable, but it is not convenient to a...
