Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a CO2 surgical field filling device used in extracorporeal circulation surgery for children's cardiac surgery. Background Art

[0002] At present, the application of CO2 surgical field filling technology in China is mainly in the adult field. There is no unified specification of CO2 exhaust pipes. All centers use oxygen tubes, urinary catheters and other pipes to make them themselves, but the pipe connection methods of each center are different and complicated.

[0003] Especially in pediatric cardiac surgery, the surgical field pipelines are complex, and children have more limited operating space than adults. In order to effectively remove the air in the surgical field by filling the surgical field with CO2 and reduce the occurrence of air embolism, it is urgent to design a CO2 surgical field filling pipeline suitable for children and apply it to the field of pediatric cardiac surgery.

[0004] Most of the traditional CO2 diffusion tubes used in clinical practice are just a straight tube for blowing, which has poor diffusion efficiency, is difficult to fix, and is easy to roll and shift during surgery. Figure 1 The diffusion head is a multi-section tube connected at different angles, which can improve the diffusion of CO2 gas. Although it can be relatively fixed in the surgical field and not easy to move, because the multi-section tubes are fixedly connected to each other and cannot be freely shaped, it has a greater impact on the surgical field, especially in children's extracorporeal circulation surgery with a small lateral thoracotomy incision.

[0005] To this end, the present application provides a CO2 surgical field filling device for use in extracorporeal circulation surgery in pediatric cardiac surgery to solve the above-mentioned technical problems.
