Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
In description of the present utility model, it is to be understood that term " multiple " is meant that at least two, such as two
It is individual, three etc., unless otherwise specifically defined.
In the utility model, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " Gu
It is fixed " etc. term should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally；Can be
Be joined directly together, can also be indirectly connected by intermediary, can be two element internals connection or two elements it is mutual
Interactively.For the ordinary skill in the art, it can understand that above-mentioned term is new in this practicality as the case may be
Concrete meaning in type.
The bone cement for ultrasonic surgical systems according to the utility model embodiment is described in detail with reference to Fig. 1-Fig. 2
Knife 10.
Shown in reference picture 1, it can be wrapped according to the bone cement knife 10 for ultrasonic surgical systems of the utility model embodiment
Include blade 1 and cutter head 2.Preferably, cutter head 2 and blade 1 are integrally formed structures.Certainly, in some unshowned implementations
In example, cutter head 2 and blade 1 can also be separate structures, and by solder bond, such cutter head 2 can use with blade 1
Different materials, performance preferably material are only applied to the position of cutter head 2, so as to save the consumption of precious materials.
Blade 1 is elongated shape rod-like structure, and its stress and transmission power are than more uniform.
Cutter head 2 is arranged on the head end of blade 1, and cutter head 2 can be used for broken bone cement and strike off bone cement.Specifically, knife
First 2 can include bit body 21 and the cover body 22 for being used to strike off bone cement of annular, and bit body 21 is arranged at the head of blade 1
End.In specific surgical procedure, the cover body 22 of the bone cement knife 10 can be used for striking off bone cement in large area.
It can be used for striking off bone cement according to the bone cement knife 10 for ultrasonic surgical systems of the utility model embodiment, together
When further enrich the species of supersonic operation cutter.
Cover body 22 is umbrella shape and has arcuate surface 221 and inner concave (another side for deviating from the arcuate surface 221).Outside
Convex surface 221 is annular, can strike off bone cement while avoid damage to bone.Further, the structure of arcuate surface 221 increases cutter head
2 surface area, and then the contact area of cutter head 2 and bone cement in surgical procedure is increased, so as to effectively accelerate scraping for bone cement
Except speed.
Thus the periphery of cover body 22 can further prevent plowing from bone and week along 222 for smooth structure and without sharp corners
Enclose soft tissue.
Bit body 21 and cover body 22 are coaxially arranged, and the effect of transmission power and motion is good, and bit body 21 can pass blade 1
Pass the mechanical wave come to be delivered to greatest extent on cover body 22, cover body 22 is played the effect for striking off bone cement.
Shown in reference picture 2, the bulge-structure 23 for crushing bone cement is provided with arcuate surface 221.Preferably, raised knot
Structure 23 is approximate cone, and the contact area of bulge-structure 23 and bone cement is smaller, so as to increase the pressure between contact surface, by
This can accelerate the broken of bone cement.In addition, bulge-structure 23 is preferably placed at the center of arcuate surface 221, it is so, raised
Structure 23 is just coaxial with blade 1, and when mechanical oscillation are passed to cutter head 2 by blade 1, bulge-structure 23 can farthest be made
Used in bone cement position, it is easy to the broken bone cement in front.By setting the cover body 22 of bulge-structure 23 and annular, the utility model
Bone cement knife 10 can both crush bone cement, bone cement can be struck off again.
Due to the insufficient strength of the too small then cutter of the diameter of blade 1, blade 1 is caused to be easily bent, and the diameter of blade 1 is too big
Be not easy to medical worker operation, thus the diameter preferred scope of blade 1 can be 2.0mm-6.0mm, further, blade 1 it is straight
Footpath preferred scope is 2.0mm-2.8mm.
Further, since blade 1 is oversize then flexible, and blade 1 is too short, and can not stretch into organization internal is operated, thus
The length preferred scope of blade 1 can be 200mm-450mm.It is further preferred that the length range of blade 1 can be 200mm-
350mm。
In certain embodiments, a diameter of 5mm-15mm of cover body 22, the height of bulge-structure 23 are 2mm-8mm.Thus, it is right
Bone cement roots out best results, substantially increases procedure efficiency.
Preferably, blade 1 is uiform section structure, transmits power and motion is more uniform.
The tail end of blade 1 can set end difference 11, flat portion 12 and connecting portion 13.End difference 11 can include multiple ladders
Axle, end difference 11 reduce the stress concentration of blade 1, can be uniformly distributed out the fatigue stress of bone cement knife 10, avoid
The phenomenon for triggering bone cement knife 10 to be broken due to the concentration of fatigue stress, which thereby enhance the service life of bone cement knife 10.
Flat portion 12 is in outer hexagonal, can be obtained by milling, and flat portion 12 facilitates operator by Cutting tool installation manner to ultrasonic handpiece, thus
Facilitate the installation of bone cement knife 10.Connecting portion 13 is used for bone cement knife 10 and the connection of the ultrasonic handpiece of ultrasonic surgical systems,
In the embodiment shown in fig. 1, connecting portion 13 can be external thread structure, and this connected mode is simple and reliable.Installation or removal
During bone cement knife 10, operator need to only turn the flat portion 12 of the tail end of blade 1 with spanner, so as to drive the precession of threaded portion or rotation
Go out, you can be easily accomplished the installation of bone cement knife 10.
Certainly, bone cement knife 10 is not limited to be threadedly coupled with the connected mode of ultrasonic handpiece, can also be riveting or clamping
It is fixed.
According to the bone cement knife of the ultrasonic surgical systems of the utility model another aspect embodiment, including above-described embodiment
10.And it has been those skilled in the art institute for other constructions of ultrasonic surgical systems, such as supersonic generator, transducer etc.
Well known known technology, therefore no longer repeat one by one here.
