Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an air bag device used for thoracic surgery. Background Art

[0002] The pleural cavity is composed of the visceral pleura that is close to the surface of the lungs and the parietal pleura that is close to the inner wall of the thorax. There is one on each side, which is not connected to each other. There is no gas in the cavity, only a small amount of serous fluid, which can reduce friction during breathing. Under normal circumstances, the cavity is negative pressure. When air accumulates in the pleural cavity, pneumothorax occurs. Artificial pneumothorax refers to a pneumothorax that is artificially inflated in the pleural cavity in order to achieve a certain purpose. The gas commonly used in artificial pneumothorax is CO2, which is mainly used in minimally invasive thoracic surgery in clinical practice. Its advantage is that artificial pneumothorax can better expose the surgical field of view, and the lung tissue in the thoracic cavity will collapse better under the action of artificial pneumothorax. However, the cost of purchasing artificial pneumothorax equipment is high. For county-level and township hospitals, there are fewer thoracic surgeries, and the utilization rate of artificial pneumothorax equipment is low, so the equipment is generally not configured. Therefore, when encountering an emergency, it is impossible to perform chest surgery on the patient immediately, and then transfer to other large hospitals, which is very likely to delay the condition. In addition, for thoracotomy, artificial pneumothorax is no longer used to expand the surgical field of view, but during the operation, gauze and cotton need to be stuffed into the pleural membrane to expand the space for surgical instruments to move and prevent the instruments from touching the pleura and causing damage. However, after the gauze and cotton absorb blood, the color of the organs becomes close. After the operation, it is time-consuming and inconvenient to remove the gauze and cotton. Summary of the invention

[0003] In order to solve the above problems, the purpose of the utility model is to provide an airbag device for thoracic surgery, which can not only be used for thoracoscopic surgery to broaden the chest field of vision, but also can be used for open surgery to expand the activity space of surgical instruments and prevent pleural damage.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An airbag device for thoracic surgery comprises an airbag, a first pipeline, a trocar and a three-way reversing valve, wherein the three-way reversing valve comprises two air outlets and an air inlet; one end of the first pipeline is connected to the airbag, and the other end of the first pipeline is connected to an air outlet of the three-way reversing valve; a gas passage is provided inside the trocar, and the gas passage connects the puncture head and the tail end of the trocar, and the tail end of the trocar is connected to the other air outlet of the three-way reversing valve, the puncture head of the trocar is connected to the external environment, and the air inlet of the three-way reversing valve is connected to an air source device.

[0006] More preferably, the puncture device is a puncture needle.

[0007] More preferably, the three-way reversing valve is arranged close to the airbag.

[0008] More preferably, the airbag device further comprises a one-way air valve, wherein the one-way air valve is respectively connected to the airbag and the first pipeline, and the three-way reversing valve is arranged away from the airbag.

[0009] More preferably, the first pipeline is a hose.

[0010] More preferably, the first pipeline is detachably connected to the one-way air valve.

[0011] The puncture device is detachably connected to the three-way reversing valve.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model relates to an airbag device for thoracic surgery. In laparoscopic surgery, gas is injected into the pleural cavity through the airbag to form a pneumothorax and open up the thoracic field of vision. In open surgery, the airbag separates the visceral pleura and the parietal pleura to expand the activity space of surgical instruments and prevent pleural damage, thus having the advantage of one thing serving two purposes.

[0021] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0022] Embodiment 1

[0023] The airbag device of this embodiment is used in minimally invasive laparoscopic surgery.

[0024] See also Figure 1 A balloon device for thoracic surgery comprises an balloon 1, a first pipeline 2, a puncture device 3 and a three-way reversing valve 4, wherein the three-way reversing valve 4 comprises two air outlets 41, 42 and an air inlet 43; one end of the first pipeline 2 is connected to the balloon 1, and the other end of the first pipeline 2 is connected to an air outlet 41 of the three-way reversing valve 4; a gas passage 31 is arranged inside the puncture device 3, and the gas passage 31 is connected to the puncture head and the tail end of the puncture device 3, and the tail end of the puncture device 3 is connected to the other air outlet 42 of the three-way reversing valve 4, the puncture head of the puncture device 3 is connected to the external environment, and the air inlet 43 of the three-way reversing valve 4 is connected to the gas source device 5.

[0025] When the airbag device is used in minimally invasive surgery, the puncture device 3 is inserted into the human body and the puncture head enters the pleural cavity 6, and the three-way reversing valve 4 is located outside the body. Therefore, the three-way reversing valve 4 is arranged close to the airbag 1, which is more convenient to operate.

[0026] The working principle of this embodiment 1 is: Figure 2 , connect the air inlet 43 of the three-way reversing valve 4 to the air source device 5, insert the puncture device 3 into the pleural cavity 6 of the human body, connect the air inlet 43 and the first pipeline 2, open the air source device 5, inflate the airbag 1, observe the air intake through the air source device 5, and after sufficient gas is filled, operate the three-way reversing valve 4 to close the passage between the air inlet 43 and the first pipeline 2, and connect the first pipeline 2 and the puncture device 3 at the same time. Since the pleural cavity 6 is originally in a negative pressure state, when the first pipeline 2 and the puncture device 3 are connected, the gas in the airbag 1 quickly enters the pleural cavity 6 to form an artificial pneumothorax. It is also possible to further squeeze the airbag 1 so that all the gas in the airbag 1 enters the pleural cavity 6. After the artificial pneumothorax is formed, operate the three-way reversing valve 4 to close the passage between the puncture device 3 and the first pipeline 2.

[0027] Embodiment 2

[0028] This embodiment is applied in open cavity surgery to separate the visceral pleura 81 closely attached to the surface of the lung 8 and the parietal pleura 91 closely attached to the inner wall of the thorax 9, thereby further expanding the activity space of the surgical instruments.

[0029] The difference between this embodiment and the first embodiment is that:

[0030] See also Figure 3, the airbag device also includes a one-way valve 7, which is respectively connected to the airbag 1 and the first pipeline 2, and the first pipeline 2 is detachably connected to the one-way valve 7. The purpose of this setting is that after the airbag 1 is inflated, the first pipeline 2 can be separated from the one-way valve 7 to prevent the first pipeline 2 and the three-way reversing valve 4 from affecting the surgical operation, while ensuring that the airbag 1 does not leak. More preferably, the first pipeline 2 is a hose, which is convenient for adjusting the position of the three-way reversing valve 4 to ensure that the placement of the airbag 1 in the human body is not affected by the change in the position of the three-way reversing valve 4. The three-way reversing valve 4 is set away from the airbag 1 to facilitate the inflation operation. Since the puncture device 3 is not needed in this embodiment, the puncture device 3 and the three-way reversing valve 4 are set to be detachably connected to facilitate the removal of the puncture device 3.

[0031] The working principle of the second embodiment: Figure 4 , remove the trocar 3, and connect the air inlet 43 of the three-way reversing valve 4 to the air source device 5. Place the uninflated airbag 1 between the visceral pleura and the parietal pleura. Turn on the air source device 5, inflate the airbag 1, and observe the air intake through the air source device 5. After the air is fully inflated, operate the three-way reversing valve 4 to close the passage between the air inlet 43 and the first pipeline 2. Remove the first pipeline 2 together with the three-way reversing valve 4 to complete the placement of the airbag device.

[0032] The utility model discloses an airbag device for thoracic surgery. In laparoscopic surgery, air is injected into the pleural cavity 6 through the airbag 1 to form a pneumothorax and expand the chest field of vision. In open surgery, the airbag 1 separates the visceral pleura and the parietal pleura to expand the activity space of surgical instruments and prevent pleural damage, which has the advantage of one object for two purposes. At the same time, the utility model airbag device has the advantages of simple structure, low cost and easy operation.

[0033] The above description is only a specific implementation method of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
