Description
Technical field
The invention belongs to medical instruments fields, in particular to what one kind singlehanded can control reversely splits core tweezer.
Background technique
Cataract refers to that intraocular crystalline lens occurs muddiness, becomes opaque by transparent, hinders light to enter intraocular, thus
It affects vision, early stage muddy slight or range does not affect vision when smaller, is then gradually weighed out to and significantly affects eyesight even mistake
It is bright.Now with the development of society, aging of population is got worse, and the morbidity of cataract of old people is also increasing, cataract
Caused visual impairment can not be by correcting with wear a pair of spectacles, and drug therapy is also difficult to obtain effective therapeutic effect, only pass through
Operation, which is only, solves the only effective method of cataract.Present most common modus operandi is cataract surgery, this operation
Operate very simple, and operation Shi doctor can hold one 2 to 3 millimeters or so of small notch on cornea, then gos deep into pen tip
Muddy crystalline lens is crushed and is absorbed by the equipment of size, then is fixed by this notch implantable artificial crystal, entire hand
Art process only needs more than ten minutes.Cataract surgery has wound is small, wound healing is fast, after-operation response is light and vision restoration is fast etc.
Advantage.
When carrying out ophthalmologic operation, it usually needs core splitting hook is used, however in the actual use process, single splits core
Hook can not reach the requirement of medical staff, or even influence the success or failure of operation, usually have the following deficiencies: 1, in microcoria
In the case of operating difficulties, single core splitting hook is inconvenient for use；2, since some operations are carried out under the conditions of non-direct-view, for hand
The doctor of art lack of experience, the drawbacks of intraoperative compliaction can often occur.
Summary of the invention
In order to solve the above technical problem, the present invention provides what one kind singlehanded can control reversely to split core tweezer, this splits core tweezer
Structure is simple, if there are two core splitting hook, can division between singlehanded control core splitting hook, and between adjustable core splitting hook away from
From.
Specific technical solution of the present invention is as follows:
What present invention offer singlehanded can control reversely splits core tweezer, and the coupler body of 6 one end of tweezer handle, coupler body are arranged in including tweezer handle

The both ends of arc shaped hook are blunt circle structure, are equipped with blade, the linear distance at the both ends of arc shaped hook on the inside of the arc-shaped bend of arc shaped hook
For 2.2mm~4.0mm, control assembly is equipped between two core splitting hooks, control assembly may be implemented under the action of by external force
The division of two core splitting hooks.
Further, the leading portion of two core splitting hooks curves inwardly and has a spacing, two core splitting hooks between control assembly
For a limit assembly, limit assembly include limit film and with the vertically disposed drive screw of limit film, one end of drive screw with
Limit film connection, the other end pass through coupler body and are plugged in tweezer handle, and the side wall of tweezer handle is equipped with group being meshed with drive screw
Dynamic stud, drive screw can move up and down in tweezer handle, and limit film can be mobile in vertical direction with drive screw.
Further, the leading portion of two core splitting hooks successively includes linkage section, bending section, vertical section and arc shaped hook, bending section
Angle with linkage section is obtuse angle and with arc transition, and the angle of vertical section and bending section is obtuse angle and uses arc transition.
Further, the bending section of two core splitting hooks is staggered in " X " type, and cross-point crosses the axis of tweezer handle.
Further, there are a curve transition, i.e. angle b in the staggered place of the bending section of two core splitting hooks, and the size of angle b is 100 °~
120°。
Further, two core splitting hook roots are integrally in the setting of " V " type, and the control assembly between two core splitting hooks includes arc
Rack gear, fixed block, the first fixinig plate and the second fixinig plate being used cooperatively with arc-shaped rack；First fixinig plate, the second fixinig plate
It is separately fixed on two core splitting hooks, fixed block joins on the first fixinig plate, and one end of arc-shaped rack is hinged on the second fixinig plate
On, the other end passes through fixed block, and arc-shaped rack can slide in fixed block, and the position for changing fixed block can be realized to arc-shaped rack
It is elastic.
Further, the side for stirring stud is engaged with drive screw, and the other side is prominent outside tweezer handle side wall.
Further, there is a cylindrical boss in one end that drive screw is connect with limit film, offers in limit film convex with column
The slot that platform matches.
Further, it stirs stud to rotate A weeks, then drive screw drives limit film to be axially moveable Amm, and two core splitting hooks
Distance change 5A/3mm.
The beneficial effects of the present invention are: one kind provided by the invention can singlehanded control reversely split core tweezer, it is easy to use,
It is capable of the division of singlehanded control core splitting hook, the neck of hook will not block the visual field of operator when surgical procedure, while be also convenient for operator
It exerts a force to core splitting hook, improves and split core efficiency.
