Description
Technical field
The utility model relates to medical instruments fields, separate in particular, being related to palpebra inferior on a kind of medical ophthalmologic operation
Fixed bracket.
Background technique
Ophthalmologic operation and the purpose of operation are to rebuild normal visual function, destructiveness will be brought to beat once intraocular infection occurs
It hits and catastrophic effect, so reducing the generation of infection, guarantees the safety of operation and operation, there is highly important clinical meaning
Justice guarantees that operation is critical that it is carried out in sterile environment with what safe operation carried out.And circumference of eyes environment such as eyelashes,
Eyelid, Meibomian gland and skin often have the pathogens such as bacterium and fungi, are the main sources of intraocular infection, are to cause intraocular infection
Occur, cause the arch-criminal of operation and operation failure.Keep gnotobasis, key is will to perform the operation and operating area and surrounding
There is the environment of bacterium to separate, although having used various easy or complicated eye speculum in recent years, can not all solve above-mentioned problem,
Achieve the purpose that reduce infection risk, improve safety and ensure good efficacy and medical resource is avoided to waste.
Therefore this patent is directed to above-mentioned existing deficiency, designs a kind of eyelid device for spreading.
Utility model content
The technical problem to be solved by the present invention is to provide palpebra inferiors on a kind of medical ophthalmologic operation separately to fix bracket,
It is convenient that eyelid is strutted to operated eye patient.
The utility model adopts the following technical solution realizes goal of the invention:
Palpebra inferior separately fixes bracket, including rack on a kind of medical ophthalmologic operation, it is characterized in that: sliding above the rack
Pass through the eccentric part of cam handle in slot by lock-screw, the central rack hole is interspersed with shifting axle, on the shifting axle
End face is contacted with the cam handle, vertical compressed spring is equipped in the rack, passing through in the vertical compressed spring has
The shifting axle, the shifting axle lower end are fixed with vertical wedge, and vertical wedge two sides inclined-plane contacts respectively right voussoir
With left voussoir, the rack lower end is fixed with two groups of guiding axis, and guiding axis described in every group is cut with scissors with the left voussoir, right voussoir respectively
It connects, is cased with two groups of horizontal compression springs on guiding axis described in every group respectively.
As further limiting for the technical program, baffle is provided on the shifting axle, the baffle is located at vertical pressure
Contracting spring upper end.
Compared with prior art, the advantages and positive effects of the utility model are as follows: rotating clockwise cam handle, make cam
Handle rim part position contact shifting axle, force shifting axle to move down, shifting axle lower end vertical wedge beveled end respectively with left voussoir, the right side
Left voussoir and right voussoir are strutted by inclined-plane when vertical wedge is moved down, make left voussoir and right voussoir by voussoir inclined-plane end in contact
End contacts eyelid, and eyelid is strutted, and distracted folding adjusts cam handle by the sliding slot of frame upper end apart from size
Upper and lower distance is adjusted, and vertical compressed spring is withstood on baffle by spring end face, baffle drives shifting axle to cam handle production
Raw pressure, when cam handle turns to dead-centre position, shifting axle will not be moved up and down.Horizontal compression spring to left voussoir and
Right voussoir generates the reaction force to come closer, makes left voussoir keep balance motionless with right voussoir, is effectively guaranteed and struts eye
Stability when eyelid, and the whole manpower of operation will not touch any position of eyelid and eyelid periphery, avoid the infection of eye.

Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
As Figure 1-Figure 5, the utility model includes rack 3, is worn in the 3 top sliding slot of rack by lock-screw 11
The eccentric part of cam handle 1 is crossed, 3 mider hole of rack is interspersed with shifting axle 4,4 upper surface of shifting axle and the cam
Handle 1 contacts, and vertical compressed spring 2 is equipped in the rack 3, passing through in the vertical compressed spring 2 has the shifting axle
4,4 lower end of shifting axle is fixed with vertical wedge 7, and the 7 two sides inclined-plane of vertical wedge contacts respectively right voussoir 5 and left wedge
Block 9,3 lower end of rack are fixed with two groups of guiding axis 8, and guiding axis 8 described in every group is cut with scissors with the left voussoir 9, right voussoir 5 respectively
It connects, is cased with two groups of horizontal compression springs 6 on guiding axis 8 described in every group respectively.
Baffle 10 is provided on the shifting axle 4, the baffle 10 is located at vertical 2 upper end of compressed spring, the locking screw
It follows closely 11 screw rod end threads and is connected with nut.
Utility model works process are as follows: when operated eye, lock-screw 11 is unclamped, because of lock-screw 11 and cam handle
1 eccentric part is hinged, and by lock-screw 11, slip band moving cam handle 1 moves up and down together along 3 upper end sliding slot of rack, by upper
Lower movement regulates to adjust the initial position of shifting axle 4 so as to the folding distance of determination left voussoir 9 and right voussoir 5
Afterwards, lock-screw 11 and nut are tightened, left voussoir 9 is individually positioned at eyelid closure with right 5 end of voussoir, is rotated clockwise
Cam handle 1, applying pressure to shifting axle 4 by 1 wheel rim position of cam handle moves down its generation, and 4 lower end of shifting axle is fixed
Have a vertical wedge 7,7 two sides inclined-plane of vertical wedge respectively with right voussoir 5,9 inclined-plane location contacts of left voussoir, when under vertical wedge 7
When shifting, right voussoir 5 can be forced to move in opposite direction with left voussoir 9 by its inclined-plane, achieve the purpose that folding, eccentric wheel locking
Mechanism can be regarded as the arc wedge being wound in shaft, when cam handle 1 rotates clockwise not because of itself radius size
With after turning to certain position, since vertical 2 lower end of compressed spring is contacted with rack, upper end withstands on 10 lower end surface of baffle, baffle
10 is fixed with shifting axle 4, and vertical compressed spring 2 can generate upward reaction force to its shifting axle 4, makes cam handle 1 and hangs down
The reaction force generated to compressed spring 2 reaches balance, and cam handle 1 no longer rotates, and the water in 3 lower section guiding axis 8 of rack
The reaction force that the right voussoir 5 of 6 pairs of flat compressed spring, left voussoir 9 generate reaches equilibrium state, completes entire eyelid and strutted
Journey.
Disclosed above is only a specific embodiment of the utility model, and still, the utility model is not limited to this,
The changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
