Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 5, a laparoscopic surgery exhaust suction system may include a three-chamber aspirator 1 and a suction bottle 2. The three-cavity aspirator 1 can move along with the ultrasonic knife and can suck away smoke generated by the ultrasonic knife in time. The three-chamber aspirator 1 has three passages independent from each other, namely, an exhaust gas suction passage 11, a waste liquid suction passage 12, and a liquid injection passage 13. The three channels are all opened at the front end of the three-cavity aspirator 1, namely, the waste gas suction channel 11, the waste liquid suction channel 12 and the liquid injection channel 13 are communicated at the front end of the three-cavity aspirator 1. The rear end of the three-cavity aspirator 1 is provided with an interface part which is respectively provided with a waste gas suction port A, a waste liquid suction port B and a liquid injection port C which are communicated with a waste gas suction channel 11, a waste liquid suction channel 12 and a liquid injection channel 13, wherein the waste gas suction port A is communicated with a first suction port 231 of the suction bottle 2, and the waste liquid suction port B is used for being connected with a negative pressure suction waste liquid collecting bottle (not shown) so as to perform waste liquid suction according to the operation requirement. The liquid injection port C is used for connecting an irrigator and can be used for flushing according to the operation requirement. The interface part at the rear end of the three-cavity aspirator 1 is also provided with a waste liquid and liquid injection switch 14 which can control the switch of the waste liquid suction port B or the liquid injection port C, namely the switch for realizing the waste liquid suction channel 12 or the liquid injection channel 13.

The attraction bottle 2 may include an outer bottle 21 and an inner bottle 22 installed inside the outer bottle 21. Wherein the outer bottle 21 is a tapered bottle so that it can maintain the stability of the suction bottle in operation. The outer bottle 21 has a detachable sealing cap 23, and the cap 23 is provided with a first suction port 231, a second suction port 232, and a water filling port 233. In the present embodiment, the water filling port 233 is located between the first suction port 231 and the second suction port 232. The diameter of the water filling port 233 is larger than the first suction port 231 and the second suction port 232. The first suction port 231 and the second suction port 232 extend to both ends (inner end and outer end). The inner ends of the first suction port 231 and the second suction port 232 are respectively connected with a hollow tube 24 and extend to the bottom of the inner bottle 22, and the outer ends are respectively connected with the waste gas suction port A of the three-cavity suction apparatus 1 and the puncture apparatus 3 through corresponding connecting tubes, so as to suck away smoke generated during the operation of the ultrasonic knife and the puncture apparatus 3. The water filling port 233 extends inward for filling the inner bottle 22 with water of a predetermined level (for example, 13 cm) while keeping the inner bottle 22 open to the outside to maintain the water surface atmospheric pressure of the inner bottle 22. The inner bottle 22 is provided with an air outlet 221 communicating with the outer bottle 21, and the outer bottle 21 is provided with a port 211 for connection with a negative pressure center (not shown). Therefore, the smoke generated during the laparoscopic surgery is absorbed by the water in the inner bottle 22 and then is sucked and discharged by the negative pressure center, and the health of medical personnel and patients is not affected.

For the convenience of assembly, the top of the inner bottle 22 is provided with three openings 222, 223 and 224 aligned with the first suction port 231, the second suction port 232 and the water filling port 233, respectively, and the openings 222, 223 and 224 protrude upward so that the two hollow tubes 24 and the water filling port 233 can be inserted into the openings 222, 223 and 224.

In the illustrated embodiment, the air outlet 221 of the inner bottle 22 is disposed on the top of the inner bottle 22, and the interface 211 of the outer bottle 21 to which the negative pressure center is connected is disposed on the sidewall of the outer bottle 21 near the top. Therefore, the flue gas absorbed by the water can be discharged in time.

Preferably, the outer bottle 21 is provided with a closed transparent viewing window 212, and the inner bottle 22 is transparent, and a scale (not shown) is provided on the body corresponding to the viewing window 212. Through the observation window 212, the water level of the inner bottle 22 can be conveniently observed, so that water can be supplemented in time, and the operation safety is ensured.

In the illustrated embodiment, the inner bottle 22 has a recess 225 on each of three sides in addition to the graduated side, the recess 225 facilitating the gripping of the inner bottle 22. Preferably, the recess 225 is oval-shaped.

Further, the bottle cap 23 is provided at the top thereof with an annular ring 234, the annular ring 234 surrounding the first suction port 231, the second suction port 232 and the water filling port 233 and not lower than the first suction port 231 and the second suction port 232. This is advantageous in preventing the connection pipes on the first suction port 231 and the second suction port 232 from being unintentionally disconnected during the operation.

The outer bottle 21 and the inner bottle 22 may be glass bottles or plastic bottles. The bottle cap 23 may be made of rubber or plastic.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
