Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.It should be noted that in the absence of conflict, the implementation in the utility model
Feature in example and embodiment can be combined with each other.It is below with reference to the accompanying drawings and in conjunction with the embodiments practical new this is described in detail
Type.
Referring to Fig. 1 and Fig. 2, it is shown in figure in lumbar intervertebral aperture mirror art provided by the embodiment of the utility model with finger pin knife
Preferred structure.As shown, the finger pin knife includes: feeler lever 1 and cutter head 2.Wherein, feeler lever 1 can be cylindrical body, and cutter head 2 can
Think elongate body, also, cutter head 2 and feeler lever 1 are arranged in angle.The first end (lower end shown in FIG. 1) of cutter head 2 and feeler lever 1
First end (lower end shown in FIG. 1) is connected, and the second end (upper end shown in FIG. 1) of cutter head 2, which is provided with, detects separation unit (in figure
It is not shown), for detecting and chorista.
Specifically, detecting separation unit can be a spherical, which is connected with the second end of cutter head 2, can also
The arcwall face in the setting of the end face of 2 second end of cutter head is thought, it is of course also possible to be other shapes, as long as being with smooth surface
Can, tissue is hurt to avoid when detecting with chorista.
Inner side edge 21 between the first end and second end of cutter head 2 offers blade, and outer side edges 22 are smooth arcwall face.
It should be noted that the angle between feeler lever 1 and cutter head 2 can be set according to the actual situation, the present embodiment
It is not limited in any way.
Separation unit is detected to detect and chorista in 2 second end of cutter head in use, first passing through, and needs to cut off when encountering
The tissue such as ligamentum flavum when, directly cut off using the blade on inner side edge 21, compared with prior art, the present embodiment is not required to
Finger pin knife is removed, but the blade directlyed adopt on finger pin knife after separating is cut off, it is not only easy to operate, but also solve
In the prior art since the cutting tools such as scissors length limiteds is to being difficult to the problem of reaching sniffing position.In addition, the present embodiment
The outer side edges 22 of middle cutter head 2 are arcwall face, avoid and hurt incoherent tissue in 22 moving process of cutter head.
In above-described embodiment, cutter head 2 is vertically arranged with feeler lever 1, this kind of set-up mode can make cutter head 2 carry out cutting behaviour
There is preferable cutting angle when making, improve cutting efficiency.
It is further continued for referring to Fig. 1, can also include: handle 3 in the various embodiments described above.Wherein, handle 3 and the second of feeler lever 1
End (upper end shown in FIG. 1) is connected.When it is implemented, handle 3 can be the column coaxially connected with feeler lever 1, also, handle
The sectional dimension of hand 3 is greater than the sectional dimension of feeler lever 1, and, the junction of handle 3 and feeler lever 1 is smooth transition, to avoid because
Sectional dimension is mutated and injures tissue.Preferably, feeler lever 1 and handle 3 are cylindrical body.The present embodiment is by being arranged than feeler lever 1
The big handle 3 of sectional dimension, can make doctor be convenient for holding in the course of surgery, make to operate more convenient flexible.
When it is implemented, the length L1 of feeler lever 1 can be 22cm, the length L3 of cutter head 2 can be 3mm, the length of handle 3
L2 can be 10cm, and diameter can be 5mm.
In addition, feeler lever 1, cutter head 2 and handle 3 can also be integrally formed, to enhance overall structural strength.
To sum up, it does not need to move when tissue need to be cut by encountering with finger pin knife in the lumbar intervertebral aperture mirror art in the present embodiment
Finger pin knife out, but the blade directlyed adopt on finger pin knife after separating is cut off, it is not only easy to operate, but also solve existing
