Trocar discharges smog.But because there is certain distance in the place and the place of release smog that produce smog, when discharging smog
Waste time and energy, influence operation technique.
In order to solve the above technical problems, prior art discloses a kind of ultrasonic cutter head with suction tube, including upper knife body, under
Cutter hub, knife bar and handle of a knife, knife bar inner transverse run through a passage, and suction tube, the tail end connection negative pressure of suction tube are provided with passage
The suction line of device.Although above-mentioned technical proposal solves above-mentioned technical problem to a certain extent, because of knife bar inner space
Limited configurations, if directly increasing by a passage, the size of whole knife bar will certainly be caused to increase, in addition, can also be to being arranged at knife
The action process of other assemblies in bar produces negative influence, so as to influence the use of whole cutter, it would be highly desirable to improve.
The content of the invention
The utility model provides one kind compared to existing technologies to solve technical problem present in known technology,
Suction tube and ultrasound knife can be mated up, realize it is quick remove smog in art, and blood in same period exhaustion visual area, disappear
Change the obstacles such as liquid, flushing liquor or fester, expose the ultrasound knife with suction tube of surgical field of view to greatest extent.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
A kind of ultrasound knife with suction tube, including：Lever and the action bars matched with the lever, the operation
Bar includes：Center working beam, hollow supporting rod outside the working beam and is socketed on outside the supporting rod
Hollow cladding bar, the cladding bar outer wall are provided with the attraction matched somebody with somebody in an arc groove and the groove and be connected to that a cross section is arc
Pipeline, the suction pipeline and the cross section formed after the cladding bar mating are sudden and violent for circle, the free end of the suction pipeline
It is exposed at outside the lever.
The utility model can also use following technical measures：The radian of the groove is less than 180 degree.
The utility model can also use following technical measures：Some intervals are respectively equipped with two cell walls of the groove to set
The buckling groove and the suction pipeline put are provided with and the one-to-one card convex of the buckling groove.
The utility model has the advantages and positive effects of：
In summary, the utility model is by providing a kind of ultrasound knife with suction tube.When ultrasound knife is in running order
When, smog will necessarily be produced, if desired suction pipeline is in running order, and doctor should be first by suction pipeline at lever
One end be connected with external negative pressure device, start negative pressure device, you can realize it is quick remove smog in art, without passing through again
The trocar of stomach wall discharges smog.
Improvement based on above-mentioned technical proposal, the outer wall construction of cladding bar is mainly optimized in the utility model, with convenient
Suction pipeline is installed thereon.Suction pipeline, it is used to directly contact smog in art to be cleaned close to one end of operative site；
Directly it can be connected on its one end close to lever with external suction pipeline, to facilitate in procedure, rapidly
Remove smog in art.In the above-mentioned technical solutions, suction pipeline can be closely installed in the groove on cladding bar, maximum limit
Degree ground reduces the knife bar size of ultrasound knife in the utility model, meanwhile, in view of after the suction pipeline and the cladding bar mating
The cross section of formation is circle, therefore can also effectively prevent the phenomenon of gas leakage in art.
Based on the improvement of above-mentioned optimal technical scheme, on the one hand the utility model, optimizes the structure ginseng of groove cross section
Number, on the premise of increase cladding bar size within reason, can expand the area of suction pipeline contact smog as far as possible, and increase attracts
Speed；On the one hand, the docked mode of suction pipeline and two cell walls in groove is also optimized, can prevent suction pipeline from performing the operation
During deviate knife bar.

Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as the technical characteristic being related in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
Embodiment one：
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are referred to, a kind of ultrasound knife with suction tube is specifically disclosed in the present embodiment.
The ultrasound knife with suction tube, including：Lever 1 and the action bars 2 matched with the lever 1, this reality
With new agent structure.
The action bars 2 includes：Center working beam 3, hollow supporting rod 4 outside the working beam 3 and
The hollow cladding bar 5 being socketed on outside the supporting rod 4, the one end of the working beam 3 and cladding bar 5 away from lever are respectively equipped with
Working arm 9 and clamping limb 8, the clamping limb 8 is articulated with cladding bar 5 and, the supporting rod 4 matched with the supporting rod 4
It is slidably connected close to one end of lever 1 and cladding bar 5, with supporting rod 4 and the change of the cladding relative position of bar 5, clamping limb 8
Can be closer or far from the working arm 9, when clamping limb 8 is close to working arm 9, the two can be by clamp tissue to be cut.
