Specific implementation process is as follows:
When carrying out laparoscopic surgery, the veress needle of pneumoperitoneum apparatus 1 is punctured from umbilical region to abdominal cavity of patients, it is right to open pneumoperitoneum apparatus 1
Injection carbon dioxide gas is in abdominal cavity of patients to form pneumoperitoneum.Then laparoscope is inserted into abdominal cavity of patients, so as to medical staff
The situation in abdominal cavity of patients is observed to go on smoothly surgical procedure.
When needing to exclude the smog in abdominal cavity of patients, 2-3 ㎝ cuts an opening above pubic symphysis, and puncture tube is opened from this
In mouth insertion abdominal cavity of patients.It protects the gathering of valve 4 to form shield under free state to be located on puncturing head 3, so can be avoided
Puncturing head 3 stabs medical staff when not in use.
For puncture tube during puncturing abdominal wall, since skin histology is more close in abdominal wall, puncture tube is by abdomen
In cavity wall the resistance of skin histology relative to its enter it is intraperitoneal after resistance it is big.Therefore in order to enable puncture tube smoothly punctures
Abdominal wall, during puncturing abdominal wall, medical staff can release puncturing head 3 from the shield that protection valve 4 is formed, and reveal
Puncturing head 3 out, convenient for puncturing.Since protection valve 4 is with flexible, puncturing head 3 can squeeze protection valve 4 when releasing, thus from anti-
It is pierced by shield.After puncturing head 3 stretches out, protection valve 4 can be collapsed again by the elasticity of itself and is adjacent on puncturing head 3, such as
State shown in FIG. 1 can so reduce the resistance that protection valve 4 is formed in puncture process.
Puncture tube enter it is intraperitoneal after, the resistance being subject to is relatively fewer, at this time can pull back puncturing head 3, i.e. court
It pulls inside shield, protection valve 4 loses to collapse again after the effect of 3 swelling of puncturing head to form shield and be located at puncture
On first 3, so it can prevent puncturing head 3 from stabbing intraperitoneal internal organs.
When needing to discharge fume, start vacuum extractor 12, vacuum extractor 12 adsorbs intraperitoneal smog from puncture core 6
It is filtered into cartridge filter 11.Puncture core 6 in the present embodiment is scalable, and medical staff is adjustable when practice punctures core
6 length is to adapt to the smoke evacuation of different location in abdominal cavity.
Vacuum extractor 12 inevitably absorbs intraperitoneal a small amount of carbon dioxide gas when attracting smog, mixes
When thering is the smog of carbon dioxide to enter in cartridge filter 11.Since operation smoke is by 95% water or vapor and 5% cell
Fragment composition, therefore after smog enters in cartridge filter 11, the first sponge block 13 in cartridge filter 11 can be by the water in smog
Steam and water absorption.Further, since the first sponge block 13 is coaxially disposed with cartridge filter 11, and the outer wall and mistake of the first sponge block 13
The inner wall of filter cylinder 11 contacts, therefore the first sponge block 13 can also stop the cell fragment in smog.Carbon dioxide in smog
Spongy layer is then passed through to be adsorbed in vacuum extractor 12, it is thus achieved that the processing of smog, while also having isolated in smog
Carbon dioxide.
Carbon dioxide after separation is temporary from being delivered in air receiver 2 in vacuum extractor 12.Full automatic pneumoperitoneum machine 1 can
It is automatic toward intraperitoneal injection carbon dioxide when intraperitoneal air pressure reduces according to preset pneumoperitoneum pressure value, therefore when smoke evacuation
The carbon dioxide of extraction can be automatically replenished by pneumoperitoneum apparatus 1.When pneumoperitoneum apparatus 1 is inflated, the interior carbon dioxide exported can flow
It moves into air receiver 2, is delivered in abdominal cavity together then as the carbon dioxide stored in air receiver 2.It is thus achieved that dioxy
Change the recycling of carbon, be not necessarily to direct emission carbon dioxide, the carbon dioxide that can be avoided discharge is good for medical staff is influenced
Health.
After a period of use, the water vapour and water adsorbed thereon is more for first sponge block 13, needs to handle it.
The first sponge block 13 that can more renew after each operation when practice, can also be driven using manual or motor if necessary
Shaft 9 rotates.Shaft 9 drives the rotation of the first sponge block 13, due to 9 eccentric setting of shaft, and the outer wall of the first sponge block 13 with
The inner wall of cartridge filter 11 contacts.Therefore when the first sponge block 13 is turned to and contacted with the bottom interior wall of cartridge filter 11, the first sea
Continuous block 13 can be extruded on the inner wall of cartridge filter 11, thus squeeze out the water adsorbed in it.The water energy of extrusion enough passes through filtering
Sieve pore 14 on cylinder 11 flows in collecting hood 10, is finally discharged from the first drainpipe 8, and when practice can be in the first drainpipe
The collection vessels such as collecting bag are connected at 8 to collect the water of discharge.
Embodiment two
As shown in figure 3, the present embodiment and embodiment one the difference is that, filter mechanism includes the mistake of shaped hollow round table
Chimney filter 17, is equipped with the second cylindrical sponge block 16 in screen pipe 17, and the outer wall of the second sponge block 16 is interior with screen pipe 17
