In the present embodiment, the circumference annular of sleeve body 21 is evenly equipped with multiple through holes, is offered on filtering body 31
Exhaust outlet corresponding with number of openings and position.
The uniformly distributed through hole of annular, can be such that operation smoke is more quickly filtered by Smoke Filter mechanism 3, and increase
Filter effect is added, same operation smoke amount, number of openings is more, its filter effect is better, and efficiency is higher.
Further, one layer of filter membrane 33 is at least set along the moving direction of operation smoke in the filtering body 31,
The side of the filter membrane 33 simultaneously sets activated carbon 34 in the filtering body 31.Filter membrane 33 is biological filtering membrane, living
Property charcoal 34 is high density active charcoal.
The quantity of filter membrane 33 can be two layers, be respectively adjacent to and set in air inlet 35 and exhaust outlet setting, activated carbon 34
Between two layers of filter membrane 33.
In order to improve exhaust effect, exhaust outlet is adjacent in filtering body 31 exhaustion plate 32, filter membrane 33 and work are set
Property charcoal 34 be arranged at exhaustion plate 32 close to the side of air inlet 35, air cavity is set in exhaustion plate 32, and exhaustion plate 32 is close to air inlet
The side of mouth 35 sets some the first stomatas 321 connected with air cavity, and second connected with exhaust outlet is also set up on exhaustion plate 32
Stomata.The size of exhaustion plate 32 can be matched with the size of the cavity of the inside of filtering body 31, be allowed each in filtering body 31
Gas after being filtered of position can enter in the air cavity of exhaustion plate 32 as soon as possible, then be discharged by exhaust outlet.
In the present embodiment, the outer wall of filtering body 31 is Nian Jie with the side wall of accommodating chamber 211 by fluid sealant.Seal gluing
Smoke Filter mechanism 3 can be not only fixed in sleeve body 21 by the mode connect, prevent it from moving or departing from sleeve body
21, operation smoke can also be prevented completely by flowing out to casing 2 between the outer wall of filtering body 31 and the side wall of accommodating chamber 211
Outside, leakproofness is enhanced.
In addition, above-mentioned design not only can be adapted for disposable puncture outfit, moreover it is possible to suitable for reused puncture
Device, when once perform the operation after, take out used Smoke Filter mechanism 3, puncture outfit is cleaned, is sterilized, dry after again
New Smoke Filter mechanism 3 is installed to reuse next time.
In other embodiments, when puncture outfit is disposable puncture device, Smoke Filter mechanism 3 can be with the one of casing 2
Shaping, i.e. casing 2 and Smoke Filter mechanism 3 use plastics integrated injection molding, specifically, the accommodating chamber 211 of sleeve body 21
Filtering body 31 is inside injection molded with, the side wall of filtering body 31 is overlapped with the side wall of accommodating chamber 211, and filtering body 31 includes leaning on
The nearly bottom plate set of cannula sheath 22 and the cover board being oppositely arranged with bottom plate, the side wall of cover board and filtering body 31 removably connect
Connect, open up air inlet 35 and exhaust outlet on the side wall of bottom plate and filtering body 31 respectively, material (the i.e. filter membrane 33 for filtering
And the grade of activated carbon 34 can be used for the material of filtration surgery smog) it is arranged between bottom plate and cover board.Puncture tube is set on bottom plate, is worn
The puncturing hole 36 on one end connection bottom plate of pipe is pierced, the other end connects the puncturing hole 36 on cover board, and puncture tube is used to supply puncturing lever 1
Pass through.
In a preferred embodiment of the invention, partition plate is set between cannula sheath 22 and sleeve body 21, on partition plate
The puncturing hole 36 passed through for puncturing lever 1 is offered, the inner wall of puncturing hole 36 is provided with for sealing sleeve pipe sheath 22 and puncturing hole 36
Between gap seal.
Air inlet 35 is offered on partition plate, Smoke Filter mechanism 3 is spiral along the side wall of the accommodating chamber 211 of sleeve body 21
The screen pipe of coiling, one end of screen pipe are connected with air inlet 35, and the other end is connected with through hole.2 He of casing of usual puncture outfit
The size of puncturing lever 1 is all without too big, therefore the space of the accommodating chamber 211 of sleeve body 21 is limited, therefore by for filtering
Screen pipe is spirally coiled on the side wall of accommodating chamber 211, it is possible to achieve small space high filtration effect, i.e., by increasing operation smoke
Filtration path improve filter effect.
In the present embodiment, for the ease of installing and replacing, screen pipe is made of flexible hose, the material choosing of screen pipe
It is made of the medical plastic for meeting medical standard.
Further, formed with the puncturing hole 36 passed through for puncturing lever 1 in the screen pipe after coiling.The inner wall of puncturing hole 36
Fitted closely with puncturing lever 1.
