Technical Field
[0001] The utility model belongs to the technical field of pneumoperitoneum machines, and particularly relates to a pneumoperitoneum machine provided with a non-contact exhaust structure. Background Technique
[0002] A laparoscope is a medical device with a miniature camera. Laparoscopic surgery uses the laparoscope to make holes in the patient's abdomen, and then places the laparoscope in the patient's abdominal cavity to observe the internal situation of the abdominal cavity by using the miniature camera carried by the laparoscope. Laparoscopic surgery requires the establishment of a pneumoperitoneum to facilitate surgical operations. Among them, a pneumoperitoneum requires a pneumoperitoneum machine, and the pneumoperitoneum machine is a special device for establishing and maintaining a pneumoperitoneum in laparoscopic surgery. The pneumoperitoneum machines in the prior art basically adopt a technical solution of using an electromagnetic valve to control the opening and closing of the exhaust pipe to achieve exhaust. However, in this technical solution, since the pipeline and the electromagnetic valve are in a connected state, it is not easy to clean the pipeline.
[0003] In response to this problem, people have also carried out exploration and research in the long-term production and life practice. For example, the Chinese utility model patent application discloses a three-stage exhaust filtration system for a pneumoperitoneum machine [Application No.: CN202123320820.3]. The utility model includes a pneumoperitoneum needle, a first filtration chamber, a second filtration chamber, a particle filter, and an electromagnetic valve that are sequentially connected through pipelines. The first filtration chamber is filled with filter cotton, and the second filtration chamber is filled with a bacterial filter screen.

[0004] Although the utility model is provided with filter cotton, the pipeline and the electromagnetic valve are still in a connected state, so there is still the problem that the pipeline is not easy to clean. Content of the Utility Model

[0018] Figure 1 It is a schematic diagram of the structure of the utility model;
[0019] Figure 2 For Figure 1 an enlarged view of part A in
[0020] In the figure: the abdominal insufflator main body 1, the front shell 2, the exhaust pipe 3, the non-contact exhaust control component 4, the installation groove 5, the face sticker board 6, the linear drive structure 41, the exhaust control frame 42, the push rod 43, the drive motor 44, the gap 45, the installation plate 46, the baffle 47. Specific implementation manner
[0021] The following further describes the present utility model in detail with reference to the accompanying drawings and specific implementation manners.
[0022] As Figure 1 shown, an abdominal insufflator provided with a non-contact exhaust structure includes an abdominal insufflator main body 1. One end of the abdominal insufflator main body 1 is provided with a front shell 2. One end of the exhaust pipe 3 extends outside the front shell 2 and communicates with the outside. The abdominal insufflator main body 1 is further provided with a non-contact exhaust control component 4 isolated from the exhaust pipe 3. One end of the non-contact exhaust control component 4 is pressed against the outer wall of the exhaust pipe 3. Starting the non-contact exhaust control component 4 can adjust the exhaust speed of the exhaust pipe 3.
[0023] In the present utility model, when in use, the gas in the abdominal insufflator can be discharged through the exhaust pipe 3. When it is necessary to switch the opening and closing state of the exhaust pipe 3, start the non-contact exhaust control component 4 to open or press the exhaust pipe 3. Therefore, the present utility model uses the non-contact exhaust control component 4 isolated from the exhaust pipe 3 to control the exhaust speed of the exhaust pipe 3. The exhaust pipe 3 is not connected to the non-contact exhaust control component 4, which facilitates the cleaning of the exhaust pipe 3.
[0024] Combined with Figure 1 and Figure 2 shown, the non-contact exhaust control component 4 includes a mutually cooperating linear drive structure 41 and an exhaust control frame 42. The exhaust control frame 42 is fixedly connected to the abdominal insufflator main body 1. The exhaust pipe 3 passes through the exhaust control frame 42. One end of the linear drive structure 41 extends into the exhaust control frame 42, and moving the linear drive structure 41 can push the exhaust pipe 3 to be pressed against the inner wall of the exhaust control frame 42.
[0025] Specifically, the linear drive structure 41 includes a drive motor 44 fixedly connected to the abdominal insufflator main body 1 and a push rod 43 drivingly connected to the drive motor 44. For example, the push rod 43 is threadedly connected to the drive motor 44. The push rod 43 is located in the exhaust control frame 42, and the end of the push rod 43 away from the drive motor 44 is pressed against the side wall of the exhaust pipe 3.
[0026] During use, start the drive motor 44. The drive motor 44 drives the push rod 43 to move back and forth along the axis of the drive shaft of the drive motor 44 through the thread, so as to realize the approach or separation of the push rod 43 from the exhaust pipe 3. When it is necessary to stop exhausting, use the push rod 43 to press the exhaust pipe 3 tightly, so that the gas cannot pass through the part of the exhaust pipe 3 that is squeezed tightly, thereby realizing the stop of gas discharge.
[0027] Preferably, the drive motor 44 is a stepping motor. The utility model uses the stepping motor to drive the push rod 43 to squeeze the exhaust pipe 3 to realize the adjustment of the exhaust speed of the exhaust pipe 3. Since the stroke of the stepping motor can be conveniently adjusted, the opening and closing degree of the exhaust pipe 3 can also be easily and accurately controlled.
[0028] As Figure 2 shown, the exhaust control frame 42 includes a mounting plate 46 fixedly connected to the main body 1 of the pneumoperitoneum machine and a baffle 47 fixedly connected to the mounting plate 46. The baffle 47 is in a relative position with the linear drive structure 41, and one outer wall of the exhaust pipe 3 is attached to the inner wall of the baffle 47.
[0029] Preferably, a gap 45 is further provided between the baffle 47 and the mounting plate 46, and the gap 45 is located directly above the exhaust pipe 3. The user can simply and conveniently observe the relative position between the exhaust pipe 3 and the push rod 43 through the gap 45.
[0030] As Figure 1 shown, a mounting groove 5 recessed into the front housing 2 is provided on the surface of the front housing 2 away from the main body 1 of the pneumoperitoneum machine, and the face sticker 6 is fitted into the mounting groove 5.
[0031] The specific embodiments described herein are merely illustrative of the spirit of the utility model. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the utility model or exceed the scope defined by the appended claims.
[0032] Although terms such as the main body 1 of the pneumoperitoneum machine, the front housing 2, the exhaust pipe 3, the non-contact exhaust control assembly 4, the mounting groove 5, the face sticker 6, the linear drive structure 41, the exhaust control frame 42, the push rod 43, the drive motor 44, the gap 45, the mounting plate 46, and the baffle 47 are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the utility model; interpreting them as any additional limitation is contrary to the spirit of the utility model.
