Description

Artificial crystal perfusion position regulator

Technical Field

The utility model relates to the field of medical equipment, concretely relates to intraocular lens fills positioning device.

Background

Myopia is a form of ametropia in which parallel rays of light enter the eye while the eye is in a accommodative relaxed state, and are focused in front of the retina, resulting in the inability to form a sharp image on the retina, known as myopic eyes (mypia). In recent years, the incidence rate of myopia in China is on a remarkable rising trend, and myopia has become a great public health problem affecting the eye health of the national people, particularly teenagers. The most common ophthalmic diseases are listed as one of three diseases in the world, the incidence rate of myopia in China is about 33 percent, which is 1.5 times of the average level of the world (accounting for 22 percent of the total population), so more and more patients can choose to carry out myopia surgery.

Currently, 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 remove spectacles. In the prior art, the position of an injected crystal needs to be adjusted in the ICL operation process, at present, viscoelastic agent is firstly injected for supporting, and then the viscoelastic agent is extracted after the operation, so that the operation difficulty is high and the process is complex. Of course, crystal positioning can be directly carried out without driving viscoelastic agents, but the mode has great operation difficulty and great risk and is abandoned.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the injection device comprises a handle 1, a positioning head 2, anti-skid lines 3, an injection pipe 4, an injection port 5, a connecting part 6, a positioning part 7, external threads 8, an injection rubber sleeve 9 and an injection port 10.

Example one

This embodiment is substantially as shown in figures 1-3 of the drawings: the intraocular lens perfusion positioner comprises a hollow handle 1 and a positioning head 2 connected to the end part of the handle 1.

Referring to fig. 2, the handle 1 is a hollow tubular structure, and the outer wall of the handle 1 is provided with anti-slip threads 3. The top end opening setting of handle 1, and the top end threaded connection of handle 1 has the filling tube 4 that is used for pouring into the special water of operation into, and the non-opening setting in bottom of handle 1, and the filling opening 5 has been seted up to the bottom of handle 1.

The positioning head 2 comprises a connecting part 6 and a positioning part 7 which are integrally formed, the connecting part 6 is in threaded connection with the bottom end of the handle 1, an included angle is arranged between the connecting part 6 and the positioning part 7, the included angle is an obtuse angle in the embodiment, the length of the connecting part 6 is 10-12mm, and the length of the positioning part 7 is 10-12 mm.

Be provided with external screw thread 8 on the bottom outer wall of handle 1, external screw thread 8 is located the top of filling opening 5, there is filling gum cover 9 (be provided with on the inner wall of filling gum cover 9 with external screw thread 8 complex internal thread) handle 1's bottom through external screw thread 8 threaded connection, it establishes the outside at transposition head 2 to fill the 9 covers of gum cover, it is the structure of tube-shape to fill gum cover 9 in this embodiment, and fill the inner chamber that gum cover 9 was provided with filling opening 5 intercommunication, the bottom of filling gum cover 9 is provided with fills mouthful 10. One end of the positioning part 7, which is far away from the handle 1, penetrates through the pouring rubber sleeve 9 and is partially positioned outside the pouring rubber sleeve 9, the length of the positioning part 7, which is positioned outside the pouring rubber sleeve 9, is 1-1.5mm, and the end part of the pouring rubber sleeve 9 and the positioning part 7 are in smooth transition.

The specific implementation process is as follows: when the patient carries out the ICL operation, need carry out the adjustment of position to the intraocular lens, before carrying out the position adjustment to the intraocular lens, at first let in the special water of operation along injection pipe 4, the special water of operation is kept somewhere in the filling opening 5 of lower extreme along the inside cavity of handle 1 to in flowing into pouring gum cover 9 from filling opening 5, in the eye of patient is flowed out from pouring opening 10 of pouring gum cover 9 bottom finally, the special water of operation plays the effect that supports the intraocular lens this moment.

Under the support of the special water for operation, the handle 1 is held by the operator, and the friction force between the hand of the operator and the handle 1 can be increased by the anti-skid grains 3, so that the phenomena of unstable holding and slipping are avoided. The operator adjusts the position of the intraocular lens by using the head of the positioning portion 7, and the handle 1, the connecting portion 6, and the positioning portion 7 are not collinear, so that the operator can avoid blocking the surgical view.

The embodiment realizes the integration of the intraocular lens supporting liquid filling and intraocular lens position adjusting device, can respectively complete the two operations through the same equipment, does not need to replace equipment in the operation process, is convenient to operate, avoids the uncertain problem of replacing the operation equipment in the process, and makes up the market blank.

Example two

As shown in fig. 4, the present embodiment is different from the first embodiment in that: in this embodiment, the diameter of the positioning portion 7 gradually decreases from the top end (the end connected to the connecting portion 6) to the bottom end, the bottom end (the end away from the connecting portion 6) of the positioning portion 7 is formed in a flat circle, and the edges of the positioning portion 7 are smoothly arranged. Correspondingly, the diameter of the pouring rubber sleeve 9 from the top end to the bottom end is gradually reduced.

In the embodiment, the diameters of the positioning part 7 and the perfusion rubber sleeve 9 are gradually reduced from the top end to the bottom end, so that the size of one end of the device, which is in contact with the eyes of a patient, can be relatively small, and the flexibility of operation can be improved; through setting up into thick structure down with filling gum cover 9, the special water of operation can have certain acceleration effect when filling gum cover 9 internal downflow, makes things convenient for the pouring of the special water of operation. As shown in fig. 5, the bottom end of the positioning portion 7 is formed into a flat circle, so that the contact area between the positioning portion 7 and the intraocular lens can be increased when the intraocular lens is positioned, and the positioning is facilitated.

The above description is only an example of the present invention, and the detailed technical solutions and/or characteristics known in the solutions are not described too much here. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
