[0002] Artificial pneumoperitoneum: Also known as pneumoperitoneum, pneumoperitoneum is the key to the success of laparoscopic surgery. Before surgery, artificial pneumoperitoneum must be established to separate the peritoneal wall from the organs, expand the abdominal cavity to facilitate surgery, and avoid damaging the organs when the trocar punctures into the abdominal cavity. When laparoscopic surgery requires the establishment of surgical space in the abdominal cavity or retroperitoneum, gas needs to be infused into the abdominal cavity to raise the anterior abdominal wall to facilitate a good field of vision and to operate with instruments. The smoke generated by the use of an electrocoagulator or laser cauterization during surgery must also be discharged in a timely manner to ensure that the intra-abdominal pressure remains within the specified range and to avoid excessive harmful gases in the abdomen causing damage to the human body.

[0003] In existing laparoscopic equipment, the surgical trachea is installed by inserting the exhaust pipe into the operating channel for connection. However, the operating channel and the exhaust pipe are only connected by plugging, which easily leads to loose installation of the surgical trachea, thereby causing smoke leakage. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Pull the two latches outward to dock the exhaust pipe and the operating pipe, insert the two plugs at the side end of the exhaust pipe into the two plug holes on the operating pipe, loosen the two latches, and drive the two latches to be inserted into the two slots respectively through the restoring force of the spring, thereby fixing the exhaust pipe and the operating pipe. The installation is convenient and quick.

[0014] 2. When performing intra-abdominal surgery, as the amount of smoke increases, the concentration of harmful gases increases and the pressure in the abdomen increases accordingly.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A laparoscopic tracheal quick connection device comprises an exhaust pipe 1 and an operating pipe 2. The exhaust pipe 1 is provided with a branch pipe 3, which is connected to the exhaust pipe 1. Two plug posts 4 are fixedly provided at the side end of the exhaust pipe 1. The operating pipe 2 is provided with a plug hole 5 adapted to the two plug posts 4. The outer wall of the operating pipe 2 is provided with a fastening assembly connected to the two plug posts 4. The fastening assembly comprises two groups of pins 12 and a spring 13. The pin 12 is arranged through the outer wall of the operating pipe 2. The spring 13 is sleeved on the outside of the pin 12. The spring 13 is in a stretched state. Both of the two plug posts 4 are provided with a slot 14 adapted to the pin 12.

[0021] By adopting the above scheme, when it is necessary to install the surgical trachea, the two pins 12 are pulled outward to connect the exhaust pipe 1 and the operating tube 2, so that the two plugs 4 at the side ends of the exhaust pipe 1 are inserted into the two plug holes 5 on the operating tube 2, and the two pins 12 are loosened. Through the restoring force of the spring 13, the two pins 12 are driven to be inserted into the two slots 14 respectively, thereby fixing the exhaust pipe 1 and the operating tube 2.

[0022] In addition, a sealing tube 6 is fixedly provided on the inner side of the exhaust pipe 1. The end of the sealing tube 6 away from the exhaust pipe 1 is inserted into the operating tube 2. The sealing tube 6 fits against the inner wall of the operating tube 2. A guide groove 15 is provided at one end of the sealing tube 6 located in the operating tube 2. By inserting the sealing tube 6 into the operating tube 2, the connection between the exhaust pipe 1 and the operating tube 2 is sealed. By providing the guide groove 15, the airflow resistance is reduced.

[0023] In addition, a sensor 7 is provided on the inner side of the exhaust pipe 1, and a switch valve 8 is provided in the branch pipe 3. The sensor 7 is electrically connected to the switch valve 8. When intra-abdominal surgery is performed, as the amount of smoke generated increases, the concentration of harmful gases increases and the pressure in the abdomen increases accordingly. When the smoke concentration reaches the set value of the sensor 7, the sensor 7 controls the switch valve 8 to open, completing the connection between the abdomen and the outside of the abdomen. The smoke in the abdomen can be discharged from the body through the operating tube 2 and the exhaust pipe 1.

[0024] In addition, an air inlet 16 is provided at one end of the operating pipe 2 away from the exhaust pipe 1 , a first exhaust port 9 is provided on the exhaust pipe 1 , and a second exhaust port 10 is provided on the branch pipe 3 .

[0025] Finally, a manual switch 11 is provided on the exhaust pipe 1 , and the connection between the branch pipe 3 and the exhaust pipe 1 is located on the left side of the manual switch 11 .

[0026] The operating principle of the utility model is now described as follows: when it is necessary to install a surgical trachea, the two latches 12 are pulled outward to connect the exhaust pipe 1 and the operating pipe 2, so that the two plug posts 4 at the side ends of the exhaust pipe 1 are inserted into the two plug holes 5 on the operating pipe 2, and the two latches 12 are released. Through the restoring force of the spring 13, the two latches 12 are driven to be inserted into the two slots 14 respectively, thereby fixing the exhaust pipe 1 and the operating pipe 2. By inserting the sealing tube 6 into the operating pipe 2, the connection between the exhaust pipe 1 and the operating pipe 2 is sealed. When performing intra-abdominal surgery, as the amount of smoke generated increases, the concentration of harmful gases increases and the pressure in the abdomen increases accordingly. When the smoke concentration reaches the set value of the sensor 7, the sensor 7 controls the switch valve 8 to open, completing the connection between the abdomen and the outside of the abdomen, and the smoke in the abdomen can be discharged from the body through the operating pipe 2 and the exhaust pipe 1.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
