Description
Technical field
This utility model relates to technical field of medical instruments, and especially a kind of Novel ophthalmic surgical is cut.
Background technology
Ophthalmologic operation is mostly microsurgery, and much, suture is the most tiny, to cutting for apparatus used relatively surgical operation precision
The requirement of cutter is the highest, and general shears inserts finger by finger ring thus is controlled, but when doctor perspires on hand,
Produce between hands and the finger ring of doctor and slide so that doctor manipulates inaccuracy, and time serious, hands also can skid off in finger ring, additionally, existing
Ophthalmologic operation cut and also lack subsidiary local lighting instrument, bring the biggest in precise and tiny operation process to medical worker
Trouble.
Notification number is that a kind of ophthalmologic operation illumination of CN205083767U is cut, and devises thumb rings and point finger ring, controls
First cutting arm, second cut arm, control the switch of illuminating lamp cutting to be additionally provided with on arm, what part solved that common shears exists asks
Topic.But from its structure, however it remains not enough, the especially direction of illumination of illuminating lamp, angle needs manually regulation, and actual
During the blade relative motion of upper two shears, during no matter how middle space reduces until engaging, cut arm, shears it
Between the normal of angle all keep constant, this most just provides the fixed installation position that can meet lighting demand for irradiation light,
Need not additionally by the auxiliary of the rotating mechanism such as rotating shaft, the collar.Secondly, in its structure, illuminating lamp needs finger operating switch
Be controlled, this precise and tiny, be fine in ultimate attainment operative process, the torsion that operating scissors is brought by any action of finger
Dynamic, vibrations are all adequate to bring about malpractice, and this lighting control mode can not accept completely.Again, institute is cut at this surgical light
In the structure stated, there is gross error with the relative position of point finger ring in thumb rings, causes in use can only holding operation
Cut.
Utility model content
The purpose of this utility model is to overcome above-mentioned technical disadvantages to provide a kind of Novel ophthalmic surgical to cut, using linkage
Formula construction of switch, LED lamp bead circuit ON when two toggles are close to each other, provide enough lighting conditions for operation technique.
This utility model solves the technical scheme of technical problem employing: a kind of Novel ophthalmic surgical is cut, including the first hinge
Bar, the second toggle and cutting edge, described first toggle, the second toggle front end be respectively connected with cutting edge, and connecting portion is provided with hinge, hinge
Front end is provided with LED lamp bead towards the position of cutting edge, and two cutting edge rear inside are provided with interior concave space, are provided with outside the first toggle
Thumb rings, is provided with a point finger ring outside the second toggle, be provided with the lithium electricity of repeatable charging outside the second toggle of point finger ring front end
Pond, offers the first cavity, the second cavity, the first cavity between the first toggle, the second toggle on the position of hinge respectively
Being provided with positive terminal in being inside equipped with negative pole arc strip, the second cavity, negative pole arc strip is positioned at the end outside the first toggle
Being provided with end socket, connecting between end socket and the first toggle has spring, the negative pole arc strip other end to stretch into the second cavity, positive terminal
Post, the end of negative pole arc strip are equipped with hard contact, and lithium battery and negative pole arc strip, positive terminal, LED lamp bead are the most electrical
Connect.First toggle, the second toggle are close, and two cutting edges are close to each other to realize shearing under hinge drives, the first toggle,
During second toggle is close to each other, negative pole arc strip front end is stretched in the second cavity and positive terminal contact, so that
The circuit ON of LED lamp bead, LED lamp bead luminous lighting, two toggles continue near time, negative pole arc strip in the first cavity to
Outer slip, it is to avoid hinder two toggles to continue close.When the first toggle, the second toggle separate, negative pole arc strip is at spring
The lower reverse slide of effect, until separating with positive terminal, LED lamp bead circuit breaker, extinguishing；Thumb rings, a point finger ring are used respectively
In being inserted in of thumb and other finger, it is to avoid operating scissors inadvertently falls off in operation；The setting of interior concave space, makes different shaped
Number, the LED lamp bead of size all can be suitable for, also will not be hindered by LED lamp bead when two cutting edges engage.
Further, the front end sleeve of described cutting edge is provided with rubber broach shell, the rear portion of described first toggle and the second toggle it
Between connect have the second spring.Due between default conditions lower scissor blade in expansion state, rubber broach shell is enclosed within cutting edge avoids accident
Scratch；Second spring is the first toggle, the separation of the second toggle provides power-assisted, and under default conditions, negative pole arc strip connects with positive pole
Terminal separates, and LED lamp bead keeps OFF state to save electricity.
This utility model had the beneficial effect that this utility model reasonable in design, uses coordinated type switch knot
Structure, when two toggles are close to each other, is positioned at the LED lamp bead circuit ON of concave space, provides enough photographs for operation technique
Bright condition, reduces the work difficulty of medical worker, improves procedure efficiency, is particularly suited for the accurate micro-control hands of clinical ophthalmology
Art.
