Technical field
The utility model relates to ophthalmologic operation technical field of tools more particularly to a kind of tweezers of ophthalmologic operation.
Background technique
Myopia laser surgey is a kind of laser surgey for treating myopia, it includes photorefractive keratectomy (Photo
Refractive Keratectomy, abbreviation PRK), Laser in Situ Keratomileusis (Lasik, abbreviation IK), quasi- point
Sub- laser ablated propulsion (LASEK, abbreviation EK), wave front aberration guide excimer laser surgery (Torsion
Lasik, abbreviation TK), femtosecond, six developing stage of full femtosecond laser.
It does not need to manufacture flip-up style cornea flap in full femtosecond laser operation whole process, is not related to excimer laser yet, but uses
Full femtosecond laser carries out the different interlayer of secondary deep in cornea interior diagonal film base and scans explosion, and formation one is complete after scanning
The lenticule shape cornea tissue thin slice of whole correction diopter makes the small corneal incision of about 3mm of non-ray laser, then with specially
Tweezers go deep into miniature incision, take out cornea tissue by small notch tweezers, complete operation.
Cornea tissue is taken out by the miniature incision, on the other hand the accuracy on the one hand requiring tweezers to take also requires
It does not damage cornea.
Therefore, it is necessary to which the tweezers for providing a kind of ophthalmologic operation meet the above technical requirements.
Utility model content
It takes out and designs specifically for cornea tissue the purpose of this utility model is to provide one kind, can be realized accurately without wound
The tweezers of harmful ophthalmologic operation.
The utility model provides a kind of tweezers of ophthalmologic operation, described including two tweezer arms that rear end is fixed together
Tweezer arm includes tail portion, hand grip portion and clamping part, and two tail portions are fixed, and two hand grip portions are opened from tail portion to be extended, described in two
Clamping part horizontal and tapered extension from the hand grip portion；The clamping part upper end is connected to the terminated site of hand grip portion, and lower end connects
It is connected to the starting position of hand grip portion, and is wedge angle to protracting.
Preferably, the wedge angle and clamping part upper end are equipped with invagination circular arc.
Preferably, the wedge angle tilts upwards from invagination circular arc.
Preferably, the wedge angle and circular arc structure in obtuse angle of invaginating.
Preferably, the outside of the clamping part is from the terminated site horizontal extension of hand grip portion, and the inside of the clamping part is certainly
The terminal position horizontal extension of the separate wedge angle of hand grip portion invagination circular arc.
Preferably, brave tooth is equipped on the inside of the wedge angle position.
Preferably, the brave tooth tilts extension from the end of the wedge angle to hand grip portion.
Preferably, the outside of the hand grip portion is equipped with anti-skid chequer.
Compared with the relevant technologies, a kind of clamping part interior lines of the tweezer arm of the tweezers of ophthalmologic operation provided by the utility model
The design of the structure of circular arc and wedge angle can accurately enter from miniature incision, clamp cornea tissue, and the taking-up of fanout free region, make
With convenient and efficient, success rate of operation height.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the tweezers of ophthalmologic operation provided by the utility model；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case where, the feature in the embodiments of the present invention and embodiment can be combined with each other.For sake of convenience, hereinafter such as
There is "upper", "lower", "left", "right" printed words, only indicates consistent with the upper and lower, left and right direction of attached drawing itself, not to structure
Play restriction effect.
As shown in Figure 1 and Figure 2, the tweezers of ophthalmologic operation provided by the utility model are fixed together by two rear ends
Tweezer arm 1 forms.The tweezer arm 1 includes tail portion 2, hand grip portion 3 and clamping part 4.
As shown in Fig. 2, two tail portions 2 are fixed, two hand grip portions 3 are opened from tail portion 2 to be extended, two clamping parts 4
From the horizontal and tapered extension of the hand grip portion 3.
As described in Figure 1, the outside of the hand grip portion 3 is equipped with anti-skid chequer 8, and the length of the tail portion 2 is greater than hand grip portion 3 and folder
Hold the sum of the length in portion 4, that is, hand grip portion 3 closes on the setting of clamping part 4, convenient convenient for preferably exerting a force when operation to clamping part 4
Operation.
4 upper end of clamping part is connected to the terminated site of hand grip portion 3, and lower end is connected to the starting position of hand grip portion 3,
That is, the plagioclase of 4 lower end of clamping part is greater than the plagioclase of upper end, in use, lower end plagioclase, towards eye, big plagioclase is convenient for eye
There are enough operating spaces in portion when performing the operation.The clamping part 4 is wedge angle 5 to extension, and the wedge angle 5 is equipped with 4 upper end of clamping part
Invaginate circular arc 6.Certainly invagination circular arc 6 tilts the wedge angle 5 upwards, and the wedge angle 5 and the structure in obtuse angle of circular arc 6 of invaginating.Wedge angle 5
With the structure of invagination circular arc 6, convenient for pushing the miniature incision of 2mm-4mm aside, and deeply enter, clamps cornea with the position of wedge angle 5
Tissue.
As described in Figure 2, the outside of the clamping part 4 is from the terminated site horizontal extension of hand grip portion 3, the clamping part 4
Inside from hand grip portion 3 invaginate circular arc 6 separate wedge angle terminal position horizontal extension.So that clamping part extend forward it is tapered, just
