Example is drawn.The utility model eliminates the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting this reality
With new.
Referring to Fig. 1 and Fig. 2, what the utility model was provided takes bone device by integrally-formed front portion 10, the and of middle part 20
Rear portion 30 is constituted.Integrally-formed technique can be such that above three part more ideally combines, and moulding process is more simple.
In order to suitable for different crowd, it is preferred that the length for taking bone device is 15cm~24cm, such as：15cm、
20cm or 24cm.For the ease of being connected with brill, being easy to medical personnel to operate, and obtain appropriate sclerotin, it is preferred that before described
The length ratio at portion 10 and middle part 20 is 1: 1~1: 1.2, and such as the two length is consistent；Described anterior 10 with the length ratio at rear portion 30
For 10: 3~5: 2, for example：Front portion 10 is 3 times of the length of rear portion 30.
Described anterior 10 include：Opening portion 11 and solid part 12, the solid part 12 are connected with the middle part 20.
The opening portion 11 is the cylindrical empty cavity configuration with opening, and it is structural that the cavity structure is got for storing
Bone grafting.The front end of the opening portion 11 is dentation cutting edge 13, for cutting sclerotin.For the ease of operation, and improve behaviour
Make accuracy, it is preferred that the direction of the dentation cutting edge 13 is clockwise.Referring to Fig. 4, the dentation cutting edge 13 is by multiple
Toothed region 131 is connected in sequence.
In order to reach it is optimal take bone effect, and ensure during bone is taken, take bone device to be accurately positioned, without
It can be shifted because of high speed rotation, the parameters of the dentation cutting edge 13 all have passed through to be calculated repeatedly.Design parameter is as follows：It is described
The angle of the long side 1311 of toothed region 131 and the interior angle of the formation of short side 1312 is 59 °~61 °, for example：59 °, 60 ° or 61 °.
The extended line on the long side 1311 of the toothed region 131 is 27 °~29 ° with the direct angle β of horizontal direction angle, for example：
27 °, 28 ° or 29 °.The length of each toothed region 131 is 2.04mm~2.06mm, for example：2.04mm, 2.05mm or
2.06mm。
Can reach most preferably takes the numerical value of bone effect as follows：The long side 1311 of the toothed region 131 is formed with short side 1312
The angle of interior angle be 60 °, the extended line on the long side 1311 of the toothed region 131 and the direct angle β of horizontal direction angle
For 28 °, the length of each toothed region 131 is 2.06mm.
There are two symmetrically arranged side openings 14 on the side wall of the opening portion 11, being symmetrical arranged for side opening 14 is conducive to
The taking-up of sclerotin during to the observation for taking bone progress and last progress bone grafting.It is preferred that, the length of the side opening 14 is 10mm
~15mm, for example：10mm, 12mm or 15mm.The length of side opening 14 is unsuitable oversize, otherwise can cause to be taken during bone is taken
Sclerotin is deflected away from from side opening 14.
The opening portion 11 and the part that the solid part 12 is connected are the conical surface raised up.The conical surface is set can be right
Take the air pressure inside bone device effectively to be adjusted, be so designed that and be more beneficial for taking being smoothed out for bone operation than plane setting.
Anterior 10 diameter is more than the diameter at the middle part 20.The diameter of the front portion 10 of bone device is taken to take bone
Amount number, take bone to operate in order to disposable completion, need the diameter by front portion 10 to do greatly in the conceived case.It is preferred that
, the internal diameter of the opening portion 11 is 8mm ± 0.1mm~14mm ± 0.1mm, for example：8.6mm, 10mm or 14.1mm.In order to
Guarantee takes bone device smoothly to cut sclerotin, and the outer wall of opening portion 11 is needed with certain thickness.Thickness is excessively thin to be caused
It withstands forces inadequate, takes and easily sustains damage during bone；And thickness is blocked up, the intensity of cutting can be reduced, and increase is produced into
This.It is preferred that, the outer wall thickness of the opening portion 11 is 2mm.
The rear portion 30 is connecting portion, and for being attached with brill, its diameter matches with brill.It is preferred that, except diameter,
The shape at rear portion 30 is also required to match with brill, referring to Fig. 3, and the rear portion 30 shown in Fig. 3 is the shape of similar pyrometric cone.And middle part
20 as connecting portion, and without larger diameter, production cost can be dramatically increased when diameter is excessive.Obviously, the diameter at middle part 20 is not yet
Can be too small, in order to reach appropriate Connected degree, front portion 20, the diameter ratio at middle part 20 and rear portion 30 is preferably：5∶4∶1.
In order to which the sclerotin taken is taken out, and it is implanted into required position, it is preferred that at described anterior 10, middle part 20 and in fact
The center of center portion 12 is provided with one along the passage 40 for taking bone device to be radially arranged.Guide pin or other needle devices can
Disclosed with the bone grafting that the opening from the end of rear portion 40 is placed in opening portion 11 through passage 40, and be implanted into required position.In order to
Guide pin is coordinated to use, it is preferred that a diameter of 2.05mm ± 0.15mm of the passage 40, for example：2.0mm, 2.08mm or
2.15mm.It is more highly preferred to, a diameter of 2.1mm of the passage 40.
Due to belonging to medical instruments field, therefore this takes the material of bone device to need to meet the use standard of medicine equipment,
It is preferred to use the preparation of medical stainless steel material.It is preferred that, the surface roughness for taking bone device is not more than 1.6, is not less than
0.4.The smaller surface of surface roughness is more smooth, but material surface roughness is lower, and production cost is also higher；And surface
It is excessively smooth, easily slide, slip out of the hand during holding.It is preferred, therefore, that being higher than 0.4 using surface roughness, less than 1.6
Material takes bone device to prepare, to reach the best price/performance ratio.
What the utility model was provided takes bone device to just need to can only take out sclerotin by the skin incision of very little, takes bone
During the wound that is caused to patient is small, bleeding is few, and cost is low, easy to operate, safe.
Although being described in detail on example embodiment and its advantage, it should be understood that do not departing from essence of the present utility model
In the case of protection domain refreshing and defined in the appended claims, these embodiments can be carried out with various change, replace and repair
Change.For other examples, one of ordinary skill in the art, which should be readily appreciated that, to keep in the utility model protection domain
Meanwhile, the order of processing step can change.
