[0022] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0023] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating directions or positional relationships, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the embodiments of the present application. In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0025] The conventional cardiac surface cooling method used by most cardiac centers in China during cardiac surgery achieves the effect of cardiac surface cooling by placing a large amount of ice chips or ice saline into the pericardial cavity. However, adding too much ice chips initially will affect the exposure of the surgical field, and fewer ice chips will turn into ice water more quickly, and as the room temperature rises, the protective effect on the myocardium decreases, so it is necessary to continuously add ice chips to the pericardial cavity. If there is no dedicated ice maker, the instrument nurse usually needs to stop the work in his hands and cut the ice, which will affect the progress of the operation and increase the burden on the instrument nurse. In addition, there is a possibility that the blood vessels on the surface of the myocardium will be scratched by sharp ice chips and cause bleeding.

[0026] The present application aims to provide a cardiac surface cooling system for use in cardiac surgery, and is particularly suitable for minimally invasive surgery with small incisions. Through unified management by an extracorporeal circulation technician, instrument nurses are freed from the work of shaving ice with blades or smashing ice with hammers. Surgeons no longer need to be distracted by the specific operation of cardiac surface cooling, but can focus on the operation itself. In addition, most cardiac centers currently routinely use carbon dioxide in open heart surgery, which can reduce the temperature while also reducing postoperative neurological complications.

[0027] In order to better understand this application, Figure 1 The cooling device for cardiac surgery according to an embodiment of the present application is described in detail.

[0028] Figure 1 A schematic structural diagram of a cooling device for cardiac surgery provided in an embodiment of the first aspect of the present application.

[0029] See also Figure 1 An embodiment of the first aspect of the present application provides a cooling device for cardiac surgery, comprising: a transport component 100, comprising a first pipeline 101, an output member 200, the output member 200 comprising a wall portion 201 and a first accommodating space 202 formed by the wall portion 201, the first accommodating space 202 is connected to the first pipeline 101, the wall portion 201 is also provided with a jet port 203 connected to the first accommodating space 202, the first pipeline 101 is used to transport cooling liquid into the first accommodating space 202, and the jet port 203 is used to discharge the cooling liquid in the first accommodating space 202 to the surface of the heart.

[0030] According to the implementation of the first aspect of the present application, the cooling device includes: a transport component 100 and an output member 200, the output member 200 includes a wall portion 201 and a first accommodating space 202 formed by the wall portion 201, and during surgery, an incision needs to be made in the chest wall and the output member 200 is placed in the chest cavity. Among them, the transport component 100 is a medical hose, and the transport component 100 includes a first pipeline 101, and the first pipeline 101 is used to transport cooling liquid into the first accommodating space 202. The cooling liquid in the first accommodating space 202 is discharged to the surface of the heart through the injection port 203, thereby achieving the effect of cooling the surface of the heart. The cooling device provided in the embodiment of the present application has a simple structure, and the first pipeline 101 can continuously transport cooling liquid into the first accommodating space 202 to achieve continuous cooling, thereby realizing the protection of the myocardium during cardiac surgery.

[0031] Optionally, both the transport component 100 and the output member 200 can be medical hoses for transporting cooling liquid. The first interface 103 is provided at one end of the first pipeline 101 extending away from the output member 200. The first interface 103 can be used to insert a medicine bottle containing reagents required for surgery. After the medicine is cooled, the cooling liquid can be transported to the first accommodation space 202 through the first pipeline 101, and the cooling liquid is discharged from the injection port 203 to the surface of the heart, thereby achieving the effect of cooling the surface of the heart.

[0032] In the embodiments of the present application, there are multiple ways to set the coolant, and the coolant can be any liquid that can be used to cool the heart and is not likely to cause excessive impact on heart surgery.

[0033] In some optional embodiments, the cooling liquid may include sterile saline. Optionally, the first pipeline 101 may be used to transport sterile saline into the first accommodating space 202, and the injection port 203 may be used to discharge the sterile saline in the first accommodating space 202 toward the heart surface.

[0034] In these optional embodiments, the first interface 103 is inserted into a medicine bottle containing sterile saline. When the sterile saline passes through the first pipeline 101, the cooling component can cool the sterile saline. After cooling, the cooled sterile saline is transported to the first containing space 202 through the first pipeline 101, and the cooled sterile saline is discharged from the injection port 203 to the surface of the heart, thereby achieving the effect of cooling the surface of the heart.

[0035] In some optional embodiments, there may be a plurality of injection ports 203 , and the plurality of injection ports 203 may be distributed at intervals along the extension direction of the output member 200 .

[0036] In these optional embodiments, multiple injection ports 203 are spaced apart along the extension direction of the output member 200 to increase the spray range of the cooling liquid, so that the peripheral side of the heart surface is cooled, further enhancing the cooling effect and thus protecting the myocardium.

[0037] In some optional embodiments, the number of the output members 200 is at least two, and the output members 200 are arranged at intervals.

[0038] In these optional embodiments, the two output members 200 are spaced apart from each other, so that the cooling liquid can be continuously sprayed on the heart surface at multiple angles for cooling by adjusting the positions of the two output members 200 .

[0039] Optionally, the number of the output components 200 may be two, which has a simple structure and is convenient for manufacturing the cooling device while also meeting the need for cooling the heart surface.

[0040] In some optional embodiments, each output member 200 is arranged around a virtual axis, and the injection port 203 is located on a side of the first accommodating space 202 facing the virtual axis.

[0041] In these optional embodiments, when the cooling device is used to cool the heart, the virtual axis position can be used to place the heart, that is, the virtual axis position can be the position of the heart when the cooling device is used to cool the heart. During the operation, the injection port 203 of each output member 200 is adjusted to be located on the side of the accommodation space facing the virtual axis, so as to spray the cooling liquid onto the surface of the heart. And the shape and position of the output member 200 are adjusted so that the output member 200 surrounds the virtual axis, that is, each output member 200 is arranged around the heart, so that the injection port 203 can be discharged from multiple directions to the surface of the heart, further enhancing the cooling effect.

[0042] Optionally, due to the different sizes of hearts of different patients, the length of the output member 200 can be 8 cm-10 cm, which can prevent the output member 200 from being too short and causing compression of the heart when it surrounds the heart, and prevent the output member 200 from being too long, which will occupy the space inside the chest cavity and affect the surgical field of view.

[0043] In some optional embodiments, the temperature reduction device further includes a first fixing member 204 connected to the output member 200 , and the first fixing member 204 is used to fix the shape of the output member 200 .

[0044] In these optional embodiments, during use, when the output member 200 surrounds the virtual axis, since the output member 200 is a hose, the relative positions of the output members 200 are not fixed. Therefore, a first fixing member 204 is provided to be connected to the output member 200. For example, the first fixing member 204 is connected to the output member 200 and the extension direction of the first fixing member 204 can be the same as the extension direction of the output member 200, so that the first fixing member 204 can fix the shape of the output member 200, thereby facilitating the output member 200 to be shaped and fixed to a state of being arranged around the heart.

[0045] Optionally, the first fixing member 204 may be a plastic metal wire, which provides support for the output member 200 so that the output member 200 can be maintained in a position around the heart with less displacement, thereby facilitating stable operation.

[0046] Optionally, since the output member 200 may be disposed close to the heart surface or even close to the heart during surgery, the first fixing member 204 may be located in the first accommodation space of the output member 200 to avoid scratching the heart surface.

[0047] Optionally, the first fixing member 204 may be fixed in the wall portion 201 without covering the injection port 203 , so as to prevent the first fixing member 204 from covering the injection port 203 during the operation, thereby affecting the discharge of the cooling liquid and the operation.

[0048] In some optional embodiments, the cooling device further includes a cooling assembly, the cooling assembly includes a second accommodating space, the second accommodating space is used to accommodate a cooling medium, and the first pipeline 101 is at least partially disposed in the second accommodating space.

[0049] In these optional embodiments, the cooling device further includes a cooling component, which includes a second accommodating space filled with a cooling medium, and the first pipeline 101 is at least partially placed in the second accommodating space to cool the agent in the first pipeline 101.

[0050] Optionally, the length of the first pipeline 101 can be 10m-12m, and the first pipeline 101 is long enough to ensure the cooling effect of the medicine. This improves the problem that the medicine is not cooled before being delivered to the output part 200 due to the short length of the first pipeline 101, thereby improving the poor cooling effect on the heart surface. It also improves the problem of wasting medical materials due to the long length of the first pipeline 101. When the length of the first pipeline 101 is 10m, it saves materials and meets the cooling demand for the medicine.

[0051] Optionally, the cooling medium may be ice water. The structure of the cooling component is not specifically limited, that is, the structure of the second accommodation space is not specifically limited, as long as the cooling medium can be stored, for example, the cooling component may be an ice bucket for ice. The structure of the cooling component may be any structure as long as it can cool the agent in the first pipeline 101 and meet the surgical requirements.

[0052] In some optional embodiments, the transport component 100 further includes a second pipeline 102, which is used to transport gas into the first accommodating space 202, and the injection port 203 is used to discharge the gas in the first accommodating space 202 to the surface of the heart.

[0053] In these optional embodiments, a second interface 104 is provided at one end of the second pipeline 102 extending away from the output element 200 . The second interface 104 is connected to a device storing gas required for surgery to transport gas into the first accommodating space 202 and discharge it to the heart surface through the injection port 203 .

[0054] Optionally, the second interface 104 may be a trumpet-shaped interface.

[0055] In some optional embodiments, the cooling device further includes a connecting pipeline 300 for connecting the transport component 100 and the output component 200 , and the cooling device further includes a second fixing component 301 for fixing the shape of the connecting pipeline 300 .

[0056] In these optional embodiments, the connecting pipeline 300 is used to connect the transport component 100 and the output component 200 , which may mean that the connecting pipeline 300 can be used to connect the first pipeline 101 , the second pipeline 102 and the first accommodation space of the output component 200 .

[0057] Optionally, the connecting pipeline 300 can form a "Y-shaped" pipeline with the first pipeline 101 and the second pipeline 102, and the first pipeline 101 and the second pipeline 102 converge at the connecting pipeline 300 to connect the first pipeline 101 and the second pipeline 102 to the first accommodation space. The cooling device also includes a second fixing member 301. During surgery, the connecting pipeline 300 needs to be bent and clamped at the chest incision for fixing. That is, the second fixing member 301 is used to fix the shape of the connecting pipeline 300.

[0058] Optionally, the second fixing member 301 may be made of the same material as the first fixing member 204. For example, the second fixing member 301 may be a plastic metal wire, which provides support for the connecting pipe 300, so that the connecting pipe 300 can be kept at the position of the chest wall opening with less displacement, which facilitates stable operation.

[0059] Optionally, the second fixing member 301 may be fixed to the inner cavity of the connecting pipeline 300 along the extension direction of the connecting pipeline 300 to avoid scratching the chest wall.

[0060] In some optional embodiments, the second pipeline 102 is used to transport carbon dioxide into the first accommodating space 202, and the injection port 203 is used to discharge the carbon dioxide in the first accommodating space 202 to the surface of the heart.

[0061] In these optional embodiments, since most cardiac centers currently routinely use carbon dioxide in open heart surgery in order to reduce the probability of postoperative neurological complications, the second interface 104 is connected to a device storing carbon dioxide to transport carbon dioxide into the first accommodation space 202 and discharge it to the heart surface through the injection port 203. Carbon dioxide is transported into the first accommodation space 202 through the second pipeline 102 and the connecting pipeline 300, and then discharged from the injection port 203 to the heart surface, thereby reducing the possibility of postoperative neurological complications.

[0062] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
