Description

Independent gas filtering component

Technical Field

The utility model relates to the field of medical equipment, in particular to an independent gas filtering assembly.

Background

In laparoscopic surgery, since organs or other tissues of the human body are pressed together, there is not enough space for observation and operation, and a pneumoperitoneum machine is required to provide pressure to enlarge the inner cavity so as to provide a proper operation space and operation field. When the conventional pneumoperitoneum machine works, the intra-abdominal pressure is lower than a set value after inflation, and the inflation valve is opened to inflate the abdominal cavity at a set flow rate. When the pressure in the abdominal cavity reaches a set value, the inflation valve is closed, and the inflation is stopped. Along with the operation, the pressure in the abdominal cavity is reduced along with the air leakage caused by the entering and exiting of the operation puncture outfit, the flushing of the abdominal cavity, the suction of flushing liquid, the sample taking out and the like. When the air pressure is lower than the set value, the inflation valve is opened again for inflation. The "inflation-pressure measurement" process of a conventional pneumoperitoneum machine is referred to as a duty cycle. The whole operation process is repeatedly repeated, and a working cycle is formed, namely, a cycle impact pressure is formed, and the impact pressure value is changed along with gas leakage in the operation process. Meanwhile, in the operation process, when the electrotome in the puncture outfit cauterizes or electrically coagulates human tissues, a large amount of smoke and water vapor are inevitably generated, the smoke generated by the combustion of the organic matters is a strong carcinogen, unnecessary injuries can be caused to operators and medical staff in an operating room, and when the deep operation of a human body is carried out, particularly when important organs such as deep blood vessels are electrocauterized, the smoke can obscure an electron microscope inside, the sight of the medical staff is influenced, the hemostasis difficulty is caused, even the operation is blind or busy, and therefore the smoothness of the operation is ensured by the smoke removing device.

The inventor researches and discovers that the existing pneumoperitoneum machine has the following defects:

the abdominal cavity has poor pressure stabilizing effect and poor smoke treatment effect.

At present, in the process of an abdominal cavity 001 operation, the pneumoperitoneum piece 200 is used for inflating the abdominal cavity 001, and when the pressure in the abdominal cavity 001 reaches a set value, the operation is carried out. During the operation, the pressure in the abdominal cavity 001 decreases, and the abdominal member 200 needs to be used again for inflation, so the operation is inconvenient. In addition, a sealing member needs to be provided in the airtight passage 310 through which the surgical instrument is inserted to prevent gas leakage, and the sealing member affects the operation of the surgical instrument.

Referring to fig. 1-7, in view of this, designers have designed a separate gas filtering assembly, which is stable in the pressure of the abdominal cavity 001, does not need to provide a sealing member, and is flexible in operation of surgical instruments.

And when the surgical instrument passes in and out of the abdomen through the instrument operation channel 312 for operation, the stability of the pressure of the abdomen is not influenced, so that the operation effect is optimized. Because the instrument operation channel 312 is not provided with a sealing part, the surgical instrument is less blocked when entering and exiting from the instrument operation channel 312, and the instrument operation channel is more flexible, convenient and convenient to use.

In addition, circulation channel 410 can adsorb smog, the flush fluid that produces in the operation process, and the function is diversified, reduces the operation degree of difficulty, improves operation effect and success rate.

Referring to fig. 2, in the present embodiment, optionally, the main body 100 includes a main cylinder 120, a circular first end cap 122, a circular second end cap 123 and a diversion plate 124. The main cylinder 120 includes an annular cylinder 121 having a circular cross section and a partition 130, and the partition 130 is connected to the annular cylinder 121 to divide the cylinder chamber of the annular cylinder 121 into three channels 110. The annular cylinder 121 and the partition 130 may be formed as an integral structure, or they may be separately manufactured and assembled. Specifically, both ends of the annular cylinder 121 are open, and the first end cap 122 and the second end cap 123 are respectively connected to both ends of the main cylinder 120 in a sealing manner. The first end cap 122 is provided with three first connectors 140, and the three first connectors 140 are respectively communicated with the three channels 110 through three first outlets. The second end cap 123 is provided with three second joints 150, and the three second joints 150 are respectively communicated with the three channels 110 through three second outlets. The partition 130 includes three connected rectangular plate bodies, one side of each of the three rectangular plate bodies is collected, and one side of each of the rectangular plate bodies opposite to the collected side is hermetically connected to the inner cylindrical wall of the annular cylinder 121. The three rectangular plate bodies and the annular cylinder body 121 together define three channels 110, three communication holes are formed in the flow dividing plate 124, the flow dividing plate 124 is arranged between the first end cover 122 and the main cylinder 120, and the three channels 110 are respectively communicated with the first joint 140 on the first end cover 122 through the three communication holes. The three passages 110 are respectively communicated with the three second connectors 150, one of the three second connectors 150 is communicated with a gas source, which may be a carbon dioxide gas source, for example, one of the three second connectors 150 is connected with a gas tank storing carbon dioxide gas. Wherein the second connector 150 may be connected to the gas tank through a pipeline, and further, a luer connector may be provided on the gas tank, and the second connector 150 may be connected to the gas tank through a corresponding luer connector.

It will be appreciated that the circulation channel 410 is in communication with the gas-tight channel line 311 and is capable of delivering gas from the gas-tight channel line 311 to the instrument working channel 312, thereby forming a gas barrier within the instrument working channel 312 and preventing gas in the abdominal cavity 001 from leaking out of the proximal end of the working instrument channel 110. That is, the second joint 150 communicating with the circulation passage 410 may communicate with the second joint 150 communicating with the airtight passage pipe 311, thereby achieving the recycling of the gas.

Further, the channel 110, which is communicated with the circulation channel 410, of the three channels 110 includes an exhaust channel and a liquid storage channel, the exhaust channel and the liquid storage channel are arranged in series, the liquid storage channel is communicated with the exhaust channel through a connecting hole, the connecting hole is formed in the inner wall of the liquid storage channel, one end of the connecting hole is communicated with the liquid storage channel, and the other end of the connecting hole is communicated with the exhaust channel.
