    I Integrated intracavity gas circulation treatment device for laparoscopic surgery Technical Field The disclosure relates to the technical field of medical apparatuses and instruments, and in particular to an integrated intracavity gas circulation treatment device for a laparoscopic surgery. Background Along with the advancement of the laparoscopic surgery technology, the laparoscopic minimally invasive surgery technology is promoted. When devices, such as an electrotome, are used for incision or electrocoagulation during a surgery process, a larger amount of smoke may be generated, this smoke may blur a mirror surface of an endoscope, and then it is caused that display content transmitted to a displayer through a camera system becomes blurred, it is the most annoying problem of a laparoscopic surgery. Therefore, this smoke must be removed in time.
    An existing common smoke removing method is that the smoke is extracted by using a negative pressure device of a hospital. Most of the extracted smoke is CO:2 and odorous smoke gas, which is directly discharged after extraction. While air pollution is caused, an air pressure in an abdominal cavity is also reduced, it may not meet requirements of an abdominal space in a surgery, and a smoothness degree of the surgery may be directly affected. Therefore, a patent document CN201720129500.4 discloses a reflux aspirator, reference to Fig. 1 for details. The reflux aspirator includes a first filtering bottle 1 (liquid storage bottle), a second filtering bottle 2 (safety bottle), a filter 3 and a piston pump 4, herein, a connecting pipe 5 is connected between the first filtering bottle 1 and the second filtering bottle 2, a connecting pipe 6 is connected between the second filtering bottle 2 and the filter 3, and a connecting pipe 7 is connected between the filter 3 and the piston pump 4.
    It may be observed from the above that the reflux aspirator includes three filtering parts (the first filtering bottle 1, the second filtering bottle 2 and the filter 3) and a driving part (the piston pump 4), liquid and gas in the abdominal cavity are extracted by the piston pump 4, and filtered through the first filtering bottle 1, the second filtering bottle 2 and the filter 3 successively. In use, each of the above components is independently installed mutually, but communicated through each connecting pipe (5/6/7), therefore the following disadvantages may be existent: 1. an overall structure of the reflux aspirator is quite complicated and cumbersome, a volume is larger, and it is very inconvenient for use and operation by a medical worker during the laparoscopic surgery; 2. multiple filtering parts and driving parts are connected by the connecting pipes (5/6/7), and a disadvantage of poor connection airtightness is existent; and 3. the multiple filtering parts and driving parts are connected by the connecting pipes (5/6/7) and repeatedly used, it may also cause a problem that a filtered gas is cross-infected again by bacteria, and a risk of the surgery is directly increased.
    Summary A purpose of the disclosure is to provide an integrated intracavity gas circulation treatment device for a laparoscopic surgery, as to solve the above problems in an existing technology. The integrated intracavity gas circulation treatment device is capable of realizing integrated installation of a filtering unit and a driving pump unit, skillful in design, compact in structure, and small in occupied space. In a process of the laparoscopic surgery, the integrated intracavity gas circulation treatment device is simply and conveniently used and operated by a medical worker. In the whole surgery process, stability of an air pressure in the abdominal cavity is high, an effect of gas circulation filtering is good, surgery efficiency and quality are improved, and it is guaranteed that a contaminated and non-sterilizable work piece (such as the driving pump) may not be repeatedly used, so real zero infection is achieved.
