Description
Technical field
The utility model is related to Medical treatment device for ophthalmologic operations tool technical field more particularly to ophthalmologic operation drag hooks.
Background technology
Currently, clinically doctor generally requires two independent drag hooks, respectively draws upper palpebra inferior when doing ophthalmologic operation
It opens, to exposure surgical field of view, this operating process is time-consuming and laborious, and operating doctor needs assistant and operated with two hands, gives operator doctor
Green hand's art brings big inconvenience, and long-term surgery, drag hook to be not easy fixed position, and unexpected risk is brought to operation.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the ophthalmologic operation proposed is drawn
Hook, it is simple in structure, can be with one-handed performance, and can fix for a long time, caused by avoiding drag hook fixed position unstable
Emergency risk facilitates being smoothed out for ophthalmologic operation.
To achieve the goals above, the utility model uses following technical solution：
Ophthalmologic operation drag hook, including hollow sleeve, the hollow sleeve inner wall are equipped with open-type through-hole, the open-type
Through-hole internal activity is socketed with mobile bar, and the mobile bar bar wall is equipped with several through-holes, and there are two the through-hole pivot bush units
Hoodle, described two hoodles are connected by spring；
One end that the mobile bar stretches out open-type via openings side is fixedly connected with centrum support plug, the mobile bar
The bar wall flexible connection of open-type via openings side is stretched out there are two supporting rod, and the one end of the supporting rod far from mobile bar is solid
Surely it is welded with steel wire, the one end of the steel wire far from mobile bar is connected with drag hook by iron wire.
Preferably, described two drag hook directions are opposite, and the height when distance of two drag hooks is opened close to eye.
Preferably, the hollow sleeve offers several centrosymmetric concave card slots along the inner wall of open-type through-hole.
Preferably, the outer diameter of the mobile bar is less than the internal diameter of open-type through-hole, the distance of two hoodles in the through-hole
Distance between equal to two symmetrical card slots, the diameter of the hoodle are more than the internal diameter of card slot.
Compared with prior art, the utility model has the beneficial effects that：
1. by the way that hollow sleeve, mobile bar and its supporting rod, steel wire and the drag hook of connection is arranged, two can be controlled simultaneously
Drag hook, and the distance between two drag hooks is controlled by centrum support plug, to realize with one hand open eyelid, this operating process side
Easy row and time saving and energy saving.
2. by the way that concave card slot is arranged in hollow sleeve inner wall, spring hoodle is set in mobile bar, realizes that mobile bar exists
It is moved in sleeve, while hoodle is stuck in card slot, and the long-time for realizing mobile bar is fixed, avoids drag hook fixed position unstable
Emergency risk caused by fixed, facilitates being smoothed out for ophthalmologic operation.
Description of the drawings
Fig. 1 be the utility model proposes ophthalmologic operation drag hook structural schematic diagram；
In figure：1 hollow sleeve, 2 open-type through-holes, 3 mobile bars, 4 through-holes, 5 hoodles, 6 centrum support plugs, 7 supporting rods, 8
Steel wire, 9 drag hooks, 10 concave card slots.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, ophthalmologic operation drag hook, including hollow sleeve 1, which is characterized in that 1 inner wall of the hollow sleeve is equipped with
Open-type through-hole 2,2 internal activity of open-type through-hole are socketed with mobile bar 3, and 3 bar wall of the mobile bar is equipped with several logical
Hole 4, there are two hoodle 5, described two hoodles 5 to be connected by spring for 4 pivot bush unit of the through-hole；
One end that the mobile bar 3 stretches out 2 opening side of open-type through-hole is fixedly connected with centrum support plug 6, the shifting
There are two supporting rods 7 for the bar wall flexible connection of 2 opening side of the stretching open-type of lever 3 through-hole, and the supporting rod 7 is far from mobile bar
3 one end is fixedly welded with steel wire 8, and the one end of the steel wire 8 far from mobile bar 3 is connected with drag hook 9 by iron wire.
9 direction of described two drag hooks is opposite, and the height when distance of two drag hooks 9 is opened close to eye.
The hollow sleeve 1 offers several centrosymmetric concave card slots 10 along the inner wall of open-type through-hole 2.
The outer diameter of the mobile bar 3 is less than the internal diameter of open-type through-hole 2, and the distance of two hoodles 5 is equal in the through-hole 4
Distance between two symmetrical card slots 10, the diameter of the hoodle 5 are more than the internal diameter of card slot 10.
The course of work of the utility model：Two drag hooks are hooked into the upper palpebra inferior in patient respectively, are pulled from hollow sleeve
Mobile bar moves a certain distance to, when the spacing of eyelid is suitble to the surgical field of view of ophthalmologic operation, will be moved in open-type through-hole
Dynamic hoodle is stuck in the card slot far from drag hook direction, realizes the fixation procedure of drag hook.At the end of operation, then gently from hollow sleeve
Cylinder pushes mobile bar, mobile hoodle to be stuck in the card slot in drag hook direction, removes drag hook, operation terminates.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
