Detailed Description
The invention is further explained below with reference to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
As shown in fig. 1 and 2, the ICL crystal taking-out forceps comprises a connecting end 1 and a mounting end 2 which are coaxially arranged, two mounting connecting pieces 3 are fixedly connected between the connecting end 1 and the mounting end 2, the two mounting connecting pieces 3 are oppositely arranged, and the connecting end 1 and the mounting end 2 are connected through the two mounting connecting pieces 3 to form an integral structure. ICL crystal takes out tweezers and still includes two application of force tweezers pieces 4 that set up relatively, application of force tweezers piece 4 with 3 intervals of erection joint piece are arranged, 4 one end fixed connection in of application of force tweezers piece connect end 1, 4 other ends of application of force tweezers piece are rotated through connection backing sheet 5 and are connected with installation column cap 6, 6 slidable mounting in installation column cap 2 in and with 2 coaxial settings in installation end, the outer end fixedly connected with transition tweezers neck 7 of installation end 2, transition tweezers neck 7 is the cavity tubular structure. The force application forceps pieces 4 are elastic pieces, and in a natural state, the force application forceps pieces and the connecting end of the installation end 2 are in a separated state.
Two forceps sheet connecting handles 8 which are oppositely arranged are sleeved in the transition forceps neck 7, one end of each forceps sheet connecting handle 8 penetrates through the corresponding mounting end 2 and is fixedly connected to the corresponding mounting column head 6, and the other end of each forceps sheet connecting handle 8 is correspondingly connected with a clamping forceps sheet 9. The transition forceps neck 7 plays a role in limiting the movement of the clamping forceps piece 9 and the force application forceps piece 4. Under the natural state, due to the self elastic action of the two force application forceps pieces 4, the two force application forceps pieces are separated from the connecting end of the mounting end head 2, the mounting column head 6 is pulled to move towards the connecting end head 1 in the separation process, the corresponding clamping forceps pieces 9 are pulled to synchronously move through the forceps piece connecting handles 8, and the parts of the two clamping forceps pieces 9 after being closed together enter the transition forceps neck 7; when the hand holds two the application of force tweezers piece 4, both close and promote installation column cap 6 orientation the direction of installation end 2 removes make two under the synchronous displacement of tweezers piece connecting handle 8 the centre gripping tweezers piece 9 outwards stretches out, and makes both be the separation form to the ICL crystal of centre gripping, after the ICL crystal of centre gripping, the release is right the holding is held between the fingers of application of force tweezers piece 4, and automatic return under its self elastic action drives two the centre gripping tweezers piece 9 presss from both sides the ICL crystal and tightly moves out the intraocular can.
Specifically, one end of the connecting support sheet 5 is rotatably mounted on the mounting column head 6, the other end of the connecting support sheet 5 is slidably mounted on the inner wall of the corresponding force application forceps sheet 4 in a limiting manner, if a T-shaped sliding groove is formed in the force application forceps sheet 4, the connecting support sheet 5 is installed in the sliding groove in a limiting manner through a connecting shaft, so that the change of the position of the lower end of the connecting support sheet 5 and the change of the inclination angle of the connecting support sheet can be adapted to the holding of the force application forceps sheet 4. The installation end 2 sets up to by application of force tweezers piece 4 to 9 diameter taper's round platform column structure of centre gripping tweezers piece, and run through installation end 2 is equipped with and is convenient for the through-hole that tweezers piece connection handle 8 passes through, the little terminal surface diameter of installation end 2 is about 4.5mm, and big terminal surface diameter is about 6mm, two maximum distance between 4 inner walls of application of force tweezers piece is 7mm, the length of application of force tweezers piece 4 is about 59mm, the thickness of application of force tweezers piece 4 is about 2.5mm, the width of erection joint piece 3 is about 2mm, and the ICL crystal of final formation takes out tweezers total length and is about 109mm, compact structure, and small, especially be fit for the ICL crystal and take out the use.
The force application tweezers sheets 4 and the installation connecting sheets 3 are respectively provided with arc sheets, and the force application tweezers sheets 4 and the installation connecting sheets 3 are wound to form a taper pipe structure which is formed by the installation end 2 to the connection end 1 in a tapering manner under a stress state, so that the whole external structure of the embodiment is regular and convenient to use. At least two be equipped with anti-skidding arc groove 10 on the outer wall of application of force tweezers piece 4 respectively, also can set up anti-skidding arc groove 10 on the outer wall of erection joint piece 3, hold between the fingers and play antiskid, anticreep effect when holding the use, make the hand hold between the fingers of taking out tweezers more firmly.
In this embodiment, the transition forceps neck 7 is provided with a transition curved portion 11, the angle of the transition curved portion 11 is 130-155 °, and after multiple trial experiments, when the angle of the transition curved portion 11 is 145 °, the operating view is optimal, and the two forceps piece connecting handles 8 are respectively provided with connecting handle curved portions corresponding to the transition curved portion 11.
As shown in fig. 1, 2 and 3, the holding forceps piece 9 is provided with an oval sheet-shaped structure, and the contact surface with the ICL crystal is provided with anti-slip patterns 12, but it is also possible to use anti-slip teeth 13 instead of the anti-slip patterns 12 (as shown in fig. 4), so that the friction force between the holding forceps piece 9 and the ICL crystal can be increased, and the firmness of holding the ICL crystal can be improved. When the anti-slip teeth 13 are arranged, the anti-slip teeth 13 on the surfaces of the two clamping forceps pieces 9 can be arranged in a staggered mode, so that the anti-slip teeth 13 are in a meshed state when the two clamping forceps pieces 9 are in a closed state, and the clamping firmness effect is better in use.
In a natural state, the mounting ends of the two force application forceps pieces 4 are in a separated state, so that the two clamping forceps pieces 9 are in a close state and partially enter the transition forceps neck 7; when the ICL crystal holding forceps are used, the two force application forceps pieces 4 are held by hands, the two holding forceps pieces 9 extend out and are slightly separated, the ICL crystal is conveniently held, the holding force on the two force application forceps pieces 4 is reduced or released after the ICL crystal is held, and the ICL crystal is clamped and moved out of an eye; the force application forceps piece 4 increases the contact area with the ICL crystal, so that the ICL crystal is good in clamping force and stable and firm in taking out, the field of view is kept good in taking out due to the arrangement of the transition forceps neck 7, and the holding force and the state of the taking out forceps are convenient to observe and adjust in real time.
The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
