The sclerite of the prominent bone of condyle is sought in space；The first light source and entirely lighting optical fiber have been installed additional in finger pin, can be clearly seen that spy
The integral position of hook and the position of end, make finger pin all the time significantly in the sight in operator；Provided with multiple secondary light sources
Towards finger pin, the direction that secondary light source irradiates is not produced shade, avoid shadow interference operator caused by finger pin.
Brief description of the drawings
Fig. 1 is the installation diagram of one embodiment of the present utility model；
Wherein：Handle 100, finger pin 200, the first finger pin section 210, the second finger pin section 220, the 3rd finger pin section 230, pointed cone
240th, entirely lighting optical fiber 250, secondary light source 300.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
A kind of condyle of mandible finger pin, including handle 100 and the finger pin 200 for being fixedly installed on the end of handle 100；Institute
State finger pin 200 and be followed successively by the first finger pin section 210, the second finger pin section 220 and the 3rd finger pin section 230 from the bottom up, described first visits
Angle between hook section 210 and the second finger pin section 220 is 140-160 degree, the second finger pin section 220 and the 3rd finger pin
Angle between section 230 is 140-160 degree；The 3rd finger pin section 230 is provided with pointed cone 240, the pointed cone 240 and the described 3rd
Angle between finger pin section 230 is 110-120 degree；The handle 100 is cylinder, the length of handle 100 be 8-15cm it
Between, the length of the first finger pin section 210 is 5-8cm, and the length of the second finger pin section 220 is 5-8cm, the 3rd finger pin section
230 length are 1-3cm, and the length of the pointed cone 240 is 0.5-1.5cm.Due to more complicated inside body openings, according to actual feelings
Condition, finger pin is set into a bent shape, consequently facilitating being shifted one's position in patient's opening, so as in more complicated and tortuous space
Seek the sclerite of the prominent bone of condyle；Angle between second finger pin section 220 and the 3rd finger pin section 230 is 140-160 degree, this angle
The tissue of stop can be got around, avoids needing further enlarged openings because apparatus can not carry out, bears patient larger
Pain.
Wherein, the first light source is provided with the handle 100, the finger pin 200 is provided with entirely lighting optical fiber 250, described logical
The bottom of body emitting optical fiber 250 is installed on first light source, and first light source is used to light the entirely lighting optical fiber 250；
The entirely lighting optical fiber 250 extends to the top of finger pin 200 from the bottom of finger pin 200；The entirely lighting optical fiber
250 are used to show the profile of finger pin 200.It is difficult when finger pin 200 seeks sclerite because the end of finger pin 200 is tip shape
Exempt to enter the position of narrow backlight, the position of the end of finger pin 200 is not known in the case of such backlight, easily hook and scrape people
Body tissue, if having installed the first light source and entirely lighting optical fiber 250 additional, can be clearly seen that finger pin 200 integral position and
The position of end, make finger pin 200 all the time significantly in the sight in operator.
In addition, the inside of the handle 100 is provided with cavity, the bottom of handle 100 is provided with end cap 110, the end cap 110 and
The handle 100 coordinates for screw thread.Due to that there can be less article in the same article performed the operation and used, such article is returned
Class storage can be conveniently a lot, tiny article are present in the cavity of handle 100, set of instrument is more concentrated, it is easier to
Preserve.
Wherein, the end of handle 100 is provided with secondary light source 300, and the secondary light source is towards the end of finger pin 200.
Secondary light source 300 is used for the position for irradiating the direction of finger pin 200, because secondary light source 300 is fixed on handle, so irradiating all the time
In the direction of the end of finger pin 200, allow the operator to clearly see the situation of the end of finger pin 200.
In addition, the secondary light source 300, at least provided with three, the secondary light source 300 is set in a manner of annular array
In the end of handle 100.Secondary light source 300 sets three, and the secondary light source 300 is towards the end of finger pin 200,
The direction for irradiating secondary light source will not produce shade, avoid shadow interference operator caused by finger pin.
In addition, the side of handle 100 and both ends are chamfering structure.By device round-corner transition structure and chamfering knot
Structure, doctor is gripped when in use more comfortable, so as to can further concentrate in the treatment, make therapeutic process more suitable
Profit.
As the supplement to above-mentioned technology, the material of the handle 100 and the finger pin 200 is stainless steel.Stainless steel
With preferable corrosion resistance, and there is enough intensity, in addition, stainless steel material is easy to get.
In addition, the handle 100 and the surface of finger pin 200 are frosted structure.Frosted structure has certain skidproof effect,
And using light fixture it is split it is intraoral observed when, the device that frosted structure is crossed is reflective weaker, reduces the interference to observer.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to scope of protection of the utility model can not be construed in any way.Based on explanation herein,
