Air exhausting device 34 is arranged in pipeline 32, and is arranged between card slot and gas outlet 33, can be by gas from patient
Abdominal cavity be pumped into pipeline 32 through air inlet 31 and from gas outlet 33 be discharged.
Filter core 35 is in round pie, can be pushed into card slot and be engaged, thus be arranged in pipeline 32 when in use,
For being filtered to remove the smog mixed in gas to gas.In the present embodiment, the size that filter core 35 filters is to receive
Meter level.
Power supply is connect with exhaust fan 34, for powering to air exhausting device 34.
Under the action of exhaust fan 34, gas is from the entrance pipeline 32 of air inlet 31 from gas outlet after the filtering of filtration core 35
33 discharges.
Escape pipe 40 is similar to the structure of air inlet pipe 10, and one end is connect (for example, being fixedly connected with the other end of gas outlet 33
Be threadedly coupled or socket) and be connected to, the other end be detachably connected (for example, be threadedly coupled or socket) on the abdominal cavity of patient from
And it is connected to the abdominal cavity of patient.Escape pipe 40 is transparent pipe.In the present embodiment, air inlet pipe 10 is removably connected by connecting pin
(for example, be threadedly coupled or be socketed) is connect on another laparoscope puncture outfit, which injects from another location suffers from
Person's is intraperitoneal.
The use process of laparoscopic surgery smoke filter 100 are as follows:
Step 1 is plugged laparoscope puncture outfit in two positions of abdominal cavity of patients.
Air inlet pipe 10 and escape pipe 40 are connected on a laparoscope puncture outfit by step 2 respectively.
Step 3, opens first switch, second switch and power supply, gas from the abdominal cavity of patient successively through air inlet pipe 10,
Abdominal cavity of patients is flowed back to after filter element 30 and escape pipe 40.
Step 4 closes first switch and the second switch, gas if it is observed that there are many smog in gas in air inlet pipe 10
Body successively flows back to abdominal cavity of patients after air inlet pipe 10, bubbler 22, filter element 30 and escape pipe 40 from the abdominal cavity of patient.
Step 5, if it is observed that in air inlet pipe 10 without smog or operation at the end of, close power supply, filter core 35 is taken out
And it saves.
The action and effect of embodiment
The laparoscopic surgery smoke filter according to involved in the present embodiment because have air inlet pipe, filter element with
And escape pipe, the gas in abdominal cavity of patients can be extracted out, be filtered to remove gas after the smog in gas again by filter element
Body is transmitted back to the intraperitoneal of patient, so can be continued in the course of surgery, effectively by laparoscopic surgery smoke filter
Intraperitoneal smog is removed on ground, and intraperitoneal gas is kept to clean, and surgical field of view can remain clear, and surgical procedure, which can guarantee, to be connected
It passes through, ensure that the health of patient and operating room technician
In addition, gas circulates in whole process, gas (CO2) amount do not lose, because without taking away abdomen
Intracavitary a large amount of heat, steady and postoperative recovery in advantageous patient's art, the pressure in abdominal cavity of patients are able to maintain that relatively stable
State.
So whole process only needs laparoscopic surgery to can be completed with smoke filter automatic work, do not need in hand
When art one assistant of specific assigned go carry out manual operation, shorten operating time, improve procedure efficiency, ensure that patient and
The health of operating room technician.
Further, laparoscopic surgery smoke filter further includes pre-filtration units, and pre-filtration units, which have, fills nothing
The bubbler of bacterium water is contaminated with the gas of smog after the pre-filtering of sterile water, and most smog can stay in water, in turn
Protect the filter membrane in filter element that it is made to avoid being blocked by a large amount of smog.
Further, pre-filtration units further include the connecting line with the first triple valve and the second triple valve, by this
Connecting line can be realized: when the amount of the smog in gas is more, gas can carry out pre-filtering by bubbler；Work as gas
In smog amount it is fewer when, gas can be directly entered filter element, not need to carry out pre-filtering by bubbler.
Further, bubbler is anti-suck bubbler, prevents the sterile water suck-back in bubbler from entering abdominal cavity of patients.
Further, the size of filter element filtering is nanoscale, can effectively be filtered to the smog in gas.
Further, air exhausting device is arranged between filter core and gas outlet, can be avoided air exhausting device by smog pollution.
Further, it is respectively provided with check valve in air inlet and air outlet, enables to gas that can only be flowed by air inlet, from
Gas outlet outflow.
Further, whether air inlet pipe and an air outlet pipe is transparent pipe, be easily and intuitively contaminated in gas in observation tube
The number of the amount of smog and smog.Bubbler is made of transparent material, the situation of sterile water in convenient intuitive observation bubbler,
When sterile water becomes cloudy, asepsis can be replaced.
Further, filter core is detachably connected in pipeline, is on the one hand convenient for changing filter core, on the other hand, under disassembly
The used filter core come can be used in chemical examination to study the ingredient of smog.
Above embodiment is the preferred case of the utility model, is not intended to limit the protection scope of the utility model.
