Description
Technical Field
The utility model belongs to the technical field of intraocular lens implantation, especially, relate to a simple and easy intraocular lens positioning water injection device.
Background
Myopia is a form of refractive error in which parallel rays of light enter the eye while the eye is in a relaxed state of accommodation and focus in front of the retina, resulting in the inability to form a sharp image on the retina, known as myopic (myopia). In recent years, the incidence rate of myopia in China is on a remarkable rising trend, and myopia becomes a great public health problem affecting the eye health of the national people, especially teenagers. The most common ophthalmic diseases are listed as one of three diseases in the world, the incidence rate of myopia of China is about 33 percent, which is 1.5 times of the average level of the world (accounting for 22 percent of the general population), so more and more patients can choose to carry out myopia surgery. Currently, the clinical myopia surgery usually includes surface laser ablation and ICL (intraocular lens implantation), which is the first choice for myopia surgery for patients with thin cornea, high myopia degree and strong desire to take off spectacles. In operation, after the lens is implanted into the anterior chamber, whether the lens can be adjusted from the anterior chamber into the posterior chamber and straightened is a key step of the operation. In general, after an incision is made, the space in the eyeball is lost due to outflow of the liquid in the eye, which is not favorable for the operation in the eye, so that the surgeon injects the liquid into the eyeball by means of a gel-like viscoelastic agent such as sodium hyaluronate to maintain the original spatial structure of the eyeball, adjusts the position of the ICL crystal implanted in the eyeball to a proper position by using an artificial lens positioning hook, finally extracts the viscoelastic agent, and replaces and supports the eyeball by using a perfusion fluid. However, current aspiration or irrigation techniques are inevitably used with some residual viscoelastic resulting in an increased risk of intra-ocular pressure build-up after surgery. Meanwhile, the viscoelastic agent is injected and then sucked only for the convenience of operation, and the viscoelastic agent is not beneficial to the operation process, so the viscoelastic agent has limited use effect.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple and easy intraocular lens positioning water injection device to solve the current positioning hook and be used limited problem when positioning intraocular lens.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a simple and easy intraocular lens positioning water injection device, includes the expansion bracket, the top of expansion bracket is equipped with the couple, be equipped with the transfusion bottle on the couple, it has the catheter to peg graft on the bottle plug of transfusion bottle, the terminal intercommunication of catheter has the positioning hook, positioning hook overcoat is equipped with the encapsulating cover.
Principle and effect of the technology: when the position of the artificial lens needs to be adjusted, the height of the telescopic frame is only required to be increased, so that the height of the hanging bottle is increased, and the operation special water in the hanging bottle flows out from the outlet of the positioning hook under the action of pressure, so that the position of the artificial lens can be adjusted while the eyeball space is supported.
Furthermore, the bottom of the glue filling sleeve is 6-10mm above the handle outlet of the positioning hook, and the front part of the glue filling sleeve is 1-2mm behind the connecting point of the positioning hook body and the head part, so that the head part of the positioning hook is completely exposed.
By adopting the scheme, the adjusting effect can be better.
Furthermore, the glue filling sleeve is connected to the position adjusting hook in a sliding mode, and the glue filling sleeve is in clearance fit with the position adjusting hook.
By adopting the scheme, the installation is convenient when in use.
Furthermore, the liquid guide pipe is provided with an anti-skid thread at one end close to the positioning hook.
By adopting the scheme, the stability of the catheter in use can be improved.
Furthermore, a flow regulator close to the hanging bottle is arranged on the liquid guide pipe.
By adopting the technical scheme, the flow rate of the operation special water in the catheter can be adjusted according to the actual situation.
Compared with the prior art, the beneficial effects of the utility model are that: the operation is simple and convenient, the flow rate of the water special for the operation is convenient to control, and the reduction of the positioning effect caused by the outflow of the water special for the operation from the incision of the eyeball of the patient can be reduced. Reduces the operation of extracting viscoelastic agent in the implanting operation of the dioptric lens, synchronously solves the problems of anterior chamber support and intraocular lens position adjustment, can effectively save the operation time and reduce the postoperative complications.

Detailed Description
The following is a more detailed description of the present invention through the following embodiments.
The embodiment is as follows: as shown in fig. 1 to 2, a simple intraocular lens positioning water injection device comprises an expansion bracket 1, wherein the expansion bracket 1 adopts an electric lifting rod, a hook 2 is connected to the top end of the expansion bracket 1 through a bolt, a hanging bottle 3 is arranged on the hook 2, and special operation water is filled in the hanging bottle 3. The opening of the transfusion bottle 3 is downward, a liquid guide pipe 4 is inserted on the bottle plug of the transfusion bottle 3, a flow regulator 5 close to the transfusion bottle 3 is sleeved outside the liquid guide pipe 4, and the flow speed of the operation special water in the liquid guide pipe 4 can be controlled through the flow regulator 5. The tail end of the liquid guide tube 4 is communicated with a position adjusting hook 6, the position adjusting hook is provided with a handle, the handle is hollow and is connected with the liquid guide tube, the external hand-held part is provided with anti-skidding threads, and the handle is a tapered body part forwards and smoothly transits to the head part of the position adjusting hook. Somatic part length is about 1.5cm, forms 130 contained angles with the handle, is the decurrent curve shape of arc, and the position adjustment hook overcoat is equipped with the sleeve cap, and the position that the sleeve cap is close the head is equipped with 3 1mm diameter openings along 360 of head, and liquid flows altogether. The sleeve cap is arranged at the head part at the most front end, the head part is in an inverted triangle shape, and the tip end is round and is arranged in an anti-skidding manner and is used for contacting a crystal face. The liquid flows into the hollow part of the positioning hook through the liquid guide pipe and flows out through the outlet at the front end of the sleeve cap and the round holes around the outlet forward. The position adjusting hook 6 is sleeved with a hollow cylindrical glue pouring sleeve 7, the glue pouring sleeve 7 is connected with the position adjusting hook 6 in a sliding mode, and the glue pouring sleeve 7 is in clearance fit with the position adjusting hook 6.
