The present invention relates to a medical cooling body capable of sucking and holding cooling water to cool a cooled part of the heart.

“Prior Art” For example, in the operation of the heart, there are some which can be operated while keeping the heart function almost normal, but in the so-called open-ended open heart surgery in which the internal lesion of the heart is operated under direct view, And the blood that enters and leaves the lungs is temporarily blocked, and during that period, an extracorporeal circulation blood circuit having a roller pump, an artificial lung, a blood circuit, etc., provided outside the body, during intracardiac surgery,
The blood flowing back from the vein is converted into arterial blood in the artificial lung, and this blood is sent from the artery to the whole body by the roller pump so that the living body theoretically maintains almost normal function while the heart and lung lose their functions. There is.

When using this extracorporeal circulation blood circuit, it is common to lower the body temperature to 15 to 30 ° C to reduce metabolism and enhance safety, and especially in the heart, a low temperature cardioplegic solution for cardioprotection. Is injected from the coronary artery to keep the temperature low.

In heart surgery, the patient should be in the recumbent position,
During surgery, the temperature of the heart easily rises due to the influence of operating lights and other temperature-related factors around the heart. Therefore, cooling water containing fine ice is stored in the heart to cool the periphery and bottom of the heart. At the same time, the surgeon assistant also cools the upper part of the heart while holding and holding a gauze cooled with cooling water on the part of the heart excluding the surgical site.

"Problems to be solved by the device" However, since the assistant presses the gauze on the upper part of the heart with the hand during the operation as described above, not only the assistant's hand is blocked but it is difficult to effectively cool the upper part of the heart. There was a problem.

The present invention has been made in view of the above circumstances, and provides a medical cooling body capable of efficiently cooling a cooled part by itself, saving the labor of an assistant, and facilitating a surgical procedure. With the goal.
