Description

Technical Field

[0001] The present application relates to the technical field of cardiothoracic surgery medical devices, and specifically to an arc-shaped nozzle structure for cardiac surgery. Background Art

[0002] Heart surgery is a type of cardiothoracic surgery. Currently, during cardiothoracic surgery in hospitals, a large amount of blood or other fluid often flows out of the surgical site of the patient's heart, covering the surgical site and affecting the surgical line of sight. In order for the doctor to see the surgical site clearly, a related nozzle device will be used to continuously flush the surgical site and at the same time suck out the fluid generated during the operation.

[0003] Related technology: Patent No. CN204910245U discloses a nozzle assembly for cardiothoracic surgery, which includes a suction pipe and a flushing pipe. The outer wall of the suction pipe is fixedly connected to the outer wall of the flushing pipe and one end of the suction pipe is aligned with one end of the flushing pipe. The nozzle assembly also includes an electric aspirator and a water pump. The suction pipe and the flushing pipe cooperate with each other to continuously flush the surgical site and suck out the accumulated fluid generated during the operation. The suction pipe of the nozzle assembly for cardiothoracic surgery is longer than the flushing pipe, so that the suction pipe can be directly extended into the accumulated fluid, while the flushing pipe is outside to prevent the end of the flushing pipe from being contaminated. However, the flushing pipes are located on one side of the suction pipe and are parallel to each other, which has limitations in flushing and is inconvenient to operate. Utility Model Content
