[0028] As shown in Figure 1 An embodiment of a laparoscopic liver lifting device includes a gasbag seat 1, a gas tube 2, and gasbag columns 3. The gas tube 2 is connected to the gasbag seat 1 at one end. Multiple gasbag columns 3 are arranged on the gasbag seat 1, and the gasbag columns 3 and the gasbag seat 1 are in communication with each other. In a laparoscopic liver surgery, the gasbag seat 1 and the gasbag columns 3 are first in a non-inflated state, and the gasbag seat 1 and the gasbag columns 3 are compressed to reduce the volume, so as to be easily inserted into the body through a minimally invasive incision of a patient. Then the gasbag seat 1 and the gasbag columns 3 are inflated through the gas tube 2. The gasbag seat 1 and the gasbag columns 3 will expand in the inflated state, and lift the liver, so that there is a certain space between the liver and the abdominal wall. Under the condition of a minimally invasive pneumoperitoneum, the abdominal wall is moved upward, the space is increased, the gasbag seat 1 is close to the abdominal wall, and the gasbag columns 3 are located under the liver. With the increase of the inflation amount, the weight of the liver acts on the gasbag columns 3 and the gasbag seat 1, thereby increasing the stability of placement. Moreover, there is a space between the gasbag columns 3, which provides a good operation space and a good surgical field, and facilitates the direct penetration of a needle holder or atraumatic forceps, thereby facilitating the operation.

[0029] As shown in Figure 2 In some embodiments of the present application, the gas tube 2 is provided with a partition along the length direction, and the gas tube 2 is divided into a first airway 20 and a second airway 21. The two airways are designed on one gas tube 2. First, the structure can be simplified, the entanglement of multiple pipelines can be reduced, and the entanglement and knotting phenomenon can be avoided, which affects the normal use. Second, the integration of the two airways into one gas tube 2 is beneficial to reduce the volume, and facilitates the insertion into the body through a minimally invasive incision of a patient.

[0030] As shown in Figure 1 and Figure 3As shown, in some embodiments of this utility model, the first air passage 20 is connected to the airbag seat 1 for inflating the airbag seat 1 and the airbag column 3. The first air passage 20 is connected to the airbag seat 1, and the airbag seat 1 is connected to the airbag column 3. By inflating the first air passage 20, gas will enter the airbag seat 1 and the airbag column 3 sequentially through the first air passage 20, so that the airbag seat 1 and the airbag column 3 are filled with gas, thereby achieving the lifting function.

[0031] like Figure 1 and Figure 3 As shown, in some embodiments of this utility model, the second airway 21 is disposed on the upper surface of the airbag seat 1 for intra-abdominal air aspiration. The second airway 21 follows the airbag seat 1 into the abdominal cavity. The second airway 21 is disposed above the airbag seat 1 and is not connected to the interior of the airbag seat 1. By aspirating air into the second airway 21, the gas in the abdominal cavity is expelled from the body along with the second airway 21, thereby achieving close-range intra-abdominal air aspiration of the operating area, removing surgical fumes from the body, providing the surgeon with a good field of vision, and facilitating the smooth progress of the surgery. It is particularly noteworthy that in laparoscopic liver surgery, because the instruments used during the operation cut tissue and generate fumes, a special air aspiration device is generally set up to remove the fumes from the abdominal cavity. However, because the air aspiration tube is far from the operating distance, the smoke removal effect is not ideal. This application provides further assistance to achieve a better air removal effect.

[0032] like Figure 1 and Figure 3 As shown, in some embodiments of this utility model, the second airway 21 is provided with a plurality of suction holes 210. The fumes generated during surgery will enter the second airway 21 through the suction holes 210 and be guided out of the body by the second airway 21.

[0033] like Figure 1As shown, in some embodiments of this utility model, the other end of the trachea 2 is connected to a three-way connector 4. The three-way connector 4 includes a first channel 40 and a second channel 41. The first channel 40 communicates with the first airway 20 and connects to the inflator 5, and the second channel 41 communicates with the second airway 21 and connects to the suction machine. The three-way connector 4 separates the two airways of the trachea 2 into independent pipes, making the pipes located outside the body relatively independent, so as to facilitate better connection to the corresponding equipment. The inflator 5 can be a rubber airbag, an air pump, or an electric air pump, etc. All the inflators 5 used above can be equipped with a one-way valve at the air inlet to prevent gas leakage after inflation, and can also intermittently supply air according to the usage to compensate for gas leakage. When using a rubber airbag, the air inlet and outlet can be reversed through a quick-release interface to achieve the suction function, so as to facilitate the removal of the airbag seat 1 and airbag column 3 after surgery. The suction machine is not shown in the figure. The suction machine can be set independently or can be a suction device, which is common knowledge in the art and will not be described in detail here.

[0034] like Figure 1 As shown, in some embodiments of this utility model, the airbag seat 1 is provided with at least two rows of airbag columns 3. The two rows of airbag columns 3 can more stably support the liver, simulating the action of a hand lifting an object upwards in reality. It should be noted that the shape of the airbag seat 1 can be regular or irregular, and can be adjusted for actual applications. It is not limited here, and designs similar in principle and structure to this application should be included in the protection scope of this application.

[0035] like Figure 1 As shown, in some embodiments of this invention, the airbag column 3 is made of a transparent material. The transparent material reduces obstruction of the surgical field, thereby making the surgical field clearer and facilitating the smooth progress of the surgery.

[0036] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0037] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any manner.
