Problems solved by technology

[0003] The main purpose of the present invention is to provide a surgical cannula with double balloons, so as to solve the phenomenon of pipeline collapse due to the relatively smooth surface of the cannula in the prior art, or the fit between the cannula and the inner wall of the arteriovenous Or the strength of the tubing is not enough, causing blood to flow out and affecting the surgical field of view, etc.

Abstract

The invention discloses a cannula used for an operation and provided with double balloons, which comprises a cannula body, the two balloons, and reinforcing ribs. A cannula wall of the cannula body isprovided with a ventilation channel, the two balloons are arranged in the cannula body in a spaced mode and are communicated with the ventilation channel, and the reinforcing ribs are embedded in thecannula body and located between the two balloons. According to the cannula, the cannula body is fixed in the vein vessel through the two balloons, and the reinforcing ribs are embedded in the cannula body between the two balloons so as to increase the strength of the cannula body between the balloons and enable the cannula for the operation to be easily inserted in the vein vessel.

Description

technical field [0001] The invention relates to the technical field of medical intubation, in particular to an operation intubation with double balloons. Background technique [0002] Cardiac surgery requires the establishment of extracorporeal circulation. The way to establish extracorporeal circulation is to split the sternum in the middle and intubate the superior and inferior vena cava to establish extracorporeal circulation. This method has a large surgical trauma, a large amount of blood loss during and after the operation, and the patient recovers slowly. If extracorporeal circulation is established through minimally invasive cannulation, such as femoral arteriovenous cannulation and jugular arteriovenous cannulation, it is characterized by direct percutaneous puncture without thoracotomy. This method has less surgical trauma and less blood loss. Extracorporeal circulation can be established in the fastest time. However, the surface of the cannula used in the current...
