The lower end of 61 is gradually moved into the position being hidden in sleeve pipe 66, when sliding bar 61 is about to mobile, owing to first is electrically connected part 72
With second be electrically connected part 73 radial direction briquetting 65 radially outward motion time separated from one another, cause electric magnet 71 lose corneal protect
Protect the sucking action of device 10 so that the lower end of sliding bar 61 can successfully depart from corneal protection device 10, to prevent corneal protection
Device 10 is taken instrument 100 and is taken out of.
When taking corneal protection device 10, user needs the lower end taking instrument 100 to be placed into corneal protection device 10
Vicinity, and press radially briquetting 65 so that radially briquetting 65 is along radial inward movement, forces top pressure slope driving slide block 62
To the lower end motion of sleeve pipe 66, release the lower ending opening of sleeve pipe 66 would fit snugly within the lower end of the sliding bar 61 in sleeve pipe 66
Outward.Owing to first part 72 and second part 73 that is electrically connected that is electrically connected can contact with each other when radial direction briquetting 654 is along radial inward movement, make
Obtain electric magnet 71 to be connected with power supply, promote electric magnet 71 to produce magnetic force, thus corneal protection device 10 is attracted to sliding bar 61
Lower end on, then user just can by take instrument 100 by corneal protection device 10 between patient's eyelid and the white of the eye take out.
Wherein, this operation needs the most with caution, to avoid corneal protection device 10 to lose the eye of patient.
In a preferred embodiment, electric magnet 71 is arranged in sliding bar 61, and the material of sliding bar 61 is resinous wood
Material.Material is the magnetic field that the sliding bar 61 of resin material does not affect electric magnet 71, to ensure that electric magnet 71 after powered up can be suitable
Corneal protection device 10 is attracted on the lower end of sliding bar 61 by profit.In addition, electric magnet 71 is arranged on the lower end of sliding bar 61
On, sliding bar 61 is also chosen as other hard material.
In a preferred embodiment, the axial cross section of slide block 62 is two L-shaped about sliding bar 61 specular,
So that slide block 62 can move smoothly.
In a preferred embodiment, radial direction briquetting 65 is provided with for preventing it from departing from the blocking junction of sleeve pipe 66
Structure.Wherein, this barrier structure can be optionally disposed on the projection on radial direction briquetting 65, and this projection is positioned at sleeve pipe 66, works as footpath
To briquetting 65 radially outward motion certain distance, this projection can lean with sleeve pipe 66, to stop radially briquetting 65 to continue
Continuous radially outward motion.
In a preferred embodiment, first part 72 and second part 73 that is electrically connected that is electrically connected is all sheet metal.Due to sheet metal
There is larger area so that first part 72 part 73 that is electrically connected with second that is electrically connected has excellent electric conductivity when contacting.
In a preferred embodiment, power supply elects lithium battery as, during to ensure that taking instrument 100 has longer use
Between.Certainly, power supply is chosen as the accumulator of other forms.
