Description
Technical field
The invention belongs to medical instruments field.It is related to a kind of medical puncture syringe needle or cutter head, and in particular to a kind of breast
Room biopsy and the spiral cutter head in three concave surfaces of rotary-cut probe.
Background technology
Breast biopsy, that is, breast biopsy pathologic finding, refer to local excision, pincers take, puncture needle inhale and scratch
The operation method such as scrape, extract, taking pathological tissues to carry out pathologic finding by patient's live body, to determine the method for diagnosis.Carry out
Breast biopsy, it is necessary to use breast biopsy and rotary-cut probe.
At present, the general breast biopsy of in the market and rotary-cut probe are generally all that the silent logical breast biopsy of american wheat is visited with rotary-cut
Pin or U.S.'s Ahmedabad breast biopsy and rotary-cut probe.Wherein, the silent logical breast biopsy of american wheat is that two concave surfaces are common with rotary-cut probe
Point of a knife, U.S.'s Ahmedabad breast biopsy and rotary-cut probe are the common point of a knife in three concave surfaces, and their insertion principle is all pushed ahead.This
Sample, before focus is inserted into can by through health tissues push focus to, not only resistance is big, and can extrude focus, therefore,
Big in the presence of insertion advance resistance, insertion smoothness is low, the shortcomings of influenceing focus.Moreover, these breast biopsies and rotary-cut probe are all
For external product, monopolized for a long time by external import producer, price is high, adds medical treatment cost.
In view of the above-mentioned technological deficiency of prior art, there is an urgent need to develop a kind of new breast biopsy and rotary-cut probe.
The content of the invention
It is an object of the invention to overcome shortcoming present in prior art, there is provided a kind of breast biopsy and rotary-cut probe
The spiral cutter head in three concave surfaces, it can reduce the advance resistance of insertion property apparatus, lift the smoothness of insertion；And foreign countries can be broken
The monopolization of manufacturer, reduces cost.
To achieve these goals, the present invention provides following technical scheme：
The spiral cutter head in three concave surfaces of a kind of breast biopsy and rotary-cut probe, it includes bit body and connecting seat, and it is special
Sign is, formed with three structure identical concave surfaces on the bit body, each formed with parabolic on the rear portion of the concave surface
Wire type aids in sword, also, spiral main sword is formed on the front portion of each concave surface, altogether formed with three on the bit body
The parabolic auxiliary sword and three spiral main swords, also, three spiral main swords are in the bit body
Top assemble and form tip, the torsion angle of each spiral main sword is 75 degree.
Further, wherein, the length of the spiral main sword is l=4mm.
Further, wherein, the length of the side of the parabolic auxiliary sword is 12mm.
Yet further, wherein, the diameter D=5.2mm of the bit body.
In addition, wherein, the diameter d=4.6mm of the connecting seat.
Further, wherein, the length L=8.56mm of the bit body.
Further, wherein, the concave surface is obtained by the way of material is removed from the bit body and its table
Surface roughness is 1.6.
With existing breast biopsy compared with the cutter head of rotary-cut probe, the three of breast biopsy of the invention and rotary-cut probe are recessed
Surface helix formula cutter head has following advantageous effects：
1st, the main sword of its front end is spiral main sword, is advanced when being inserted using rotary, with pushing away for existing cutter head
Enter formula advance to compare, it can reduce the advance resistance of insertion property apparatus, lift the smoothness of insertion.
2nd, the design of the spirally torsion angle and cutter head overall dimensions of main sword is passed through so that its advance resistance is minimum, insertion
It is most smooth, and reduce extruding of the health tissues to focus so that biopsy is easily and accurate.
3rd, it can break monopolization of the foreign vendor to breast biopsy and rotary-cut probe cutter head, reduce the dependence to import,
And cost can be reduced.

Embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the content of embodiment is not as the guarantor to the present invention
Protect the limitation of scope.
As illustrated in fig. 1 and 2, the spiral cutter head in three concave surfaces of breast biopsy of the invention and rotary-cut probe includes bit body
1 and connecting seat 2.Wherein, the bit body 1 is used to be pierced into breast to obtain lesion tissue.The connecting seat 2 be used for
The knife bar of probe is connected, in order to which doctor is operated.In the present invention, it is preferred to the bit body 1 and connecting seat 2 are
One.When in use, the spiral cutter head in three concave surfaces is connected on knife bar by the connecting seat 2, and doctor holds knife bar progress
Rotation, makes the bit body 1 be threadingly advanced in breast, realizes the acquisition of lesion tissue.
As Figure 1-4, in the present invention, formed with three structure identical concave surfaces 1.1 on the bit body 1.Its
In, aid in sword 1.2 formed with parabolic on the rear portion of each concave surface 1.1.It is, the rear portion of the concave surface 1.1
Defined by parabolic auxiliary sword 1.2 on border.Also, the parabolic auxiliary sword 1.2 of two adjacent concave surfaces 1.1 is each other
It is intersecting, form interface point 1.5.
Meanwhile form two spiral main swords 1.3 on the front portion of each concave surface 1.1.It is, the concave surface 1.1
Anterior border defined by two spiral main swords 1.3.
It is also, described spiral formed with three parabolic auxiliary swords 1.2 and three altogether on the bit body 1
Main sword 1.1.Meanwhile three spiral main swords 1.3 are assembled on the top of the bit body 1 and form tip 1.4.Also
It is that at described sophisticated 1.4, the other end is located at the interface point 1.5 for one end of each spiral main sword 1.3.
Also, in the present invention, as shown in figure 3, the torsion angle of each spiral main sword 1.3 is 75 degree.
In the present invention, because the breast biopsy and the main sword of the front end of the spiral cutter head in three concave surfaces of rotary-cut probe are
Spiral main sword, therefore, advanced when being inserted using spiral, with existing cutter head it is pusher advance compared with, it can be with
The advance resistance of insertion property apparatus is reduced, lifts the smoothness of insertion.Meanwhile unique torsion angle of spiral main sword causes it
Resistance is minimum, insertion is most smooth.
As shown in figure 4, in the present invention, the length of the spiral main sword 1.3, it is, from described sophisticated 1.4 to institute
The air line distance for stating interface point 1.5 is l=4mm.Also, the length of the parabolic auxiliary sword 1.2, it is, whole throw
The length of thing line is 12mm.
In addition, in the present invention, the diameter D=5.2mm of the bit body 1.The diameter d=of the connecting seat 2
4.6mm.Also, the length L=8.56mm of the bit body 1.
So, this design of cutter head overall dimensions is passed through so that its advance resistance is minimum, insertion is most smooth, and reduces
Extruding of the health tissues to lesion tissue so that biopsy is easily and accurate.
Finally, in the present invention, it is preferred to, the concave surface 1.1 from the bit body 1 by the way of material is removed
Obtain and its surface roughness is 1.6.So so that it inserts more convenient.
The breast biopsy of the present invention can not only reduce insertion property apparatus with the spiral cutter head in three concave surfaces of rotary-cut probe
Advance resistance, lift the smoothness of insertion.Most importantly, it has broken foreign vendor to breast biopsy and rotary-cut probe cutter head
Monopolization, reduce the dependence to import, cost can be reduced, benefit hospital and patient.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention
Embodiment restriction.For those of ordinary skill in the field, can also make on the basis of the above description
Other various forms of changes or variation.Here all embodiments can not be exhaustive.Every skill for belonging to the present invention
Row of the obvious changes or variations that art scheme is extended out still in protection scope of the present invention.
