Description

Intraocular lens storage case and intraocular lens implantation method

Technical Field

The present invention relates to an intraocular lens storage case in which an intraocular lens is preloaded and a method of implanting an intraocular lens using the same.

Background

Intraocular lenses (IOLs) are an artificial lens that is implanted in an eye to replace the natural crystalline lens when the eye of a person suffers from cataracts or other diseases to correct refractive errors of the eye. Because of the flexibility of the material and small size of the intraocular lens itself, it is difficult to directly perform surgical procedures on it, and thus it is desirable to implant it into the eye through a minimally invasive surgical port using an auxiliary medical instrument.

Conventional intraocular lens implantation systems consist of an aircraft nose and an implanter body. During the operation, the medical staff takes out the individually packaged artificial lens from the package and puts the artificial lens into the injector for implantation, and then implants the artificial lens. Since the loading process is entirely dependent on the skill of the healthcare worker for the procedure, there is a large uncertainty factor. If the medical staff performing the operation is less skilled, the operation time can be prolonged greatly, and even the artificial damage to the artificial lens can be caused. In addition, since the operators may make the loading state (loading angle, etc.) of the intraocular lens different, misoperation is easy to occur, so that the state of the intraocular lens which is presented after being pushed into the eyes is poor (in extreme cases, the positive and negative inversion may be caused), and the intraocular lens needs to be corrected again, thereby increasing the risk of operation.

Therefore, it is desirable to design an intraocular lens implantation system that reduces the difficulty of operation of the implantation process, and that does not suffer from the skill of the operator, to ensure that the implanted state of the intraocular lens is always good.

A preloaded intraocular lens injector disclosed in patent document 1 includes a retainer, the retainer and IOL being removably mounted to the injector body and sealed in the same package for delivery to a practitioner. The retainer and IOL are connected together and sealed in one package, the injector body is sealed in a separate package, and the surgeon installs the retainer to the injector body at the time of surgery. To deliver the IOL through the injector body, the retainer is removed from the injector body, thereby causing the IOL to be released from the retainer and placed into the injector body in an unstressed state. The compression member is moved to a closed position to compress the IOL, the injector tip is inserted into a small incision in the eye, and the plunger is advanced to push the IOL through the injector body tip and thereby discharge into the eye.

< Structure of intraocular lens storage case >

Fig. 1 is a schematic view showing the structure of an intraocular lens storage case according to the present invention. As shown in fig. 1, the storage case 2 includes a case 21, and the case 21 has a flat plate portion 211 formed in a flat plate shape. A bolus channel 215 is provided at one end of the cartridge 21, and the bolus channel 215 is formed as an arc channel with a bottom surface recessed downward. A channel outer wall 216 is formed on a side of the bolus channel 215 remote from the flat plate portion 211, and a channel inner wall 214 is formed on a side adjacent to the flat plate portion 211, the height of the channel inner wall 214 being slightly lower than the channel outer wall 216. A pair of slide grooves 218 are formed on both sides in the longitudinal direction of the flat plate portion 211 of the case 21, and the length of the slide grooves 218 is shorter than the length of the flat plate portion 211 of the case 21.

The case 2 further includes a base 25, and the base 25 has a pair of side edges 252 on both sides thereof, and a groove is formed on the inner side of the side edges 252, in which a slide groove 218 of the case 21 slides, so that the case 21 is assembled with the base 25 in a freely slidable manner. As shown in fig. 1, a side limit block 253 is further disposed on the side 252, and when the box 21 is assembled with the base 25, the side limit block 253 abuts against the inner wall 214 of the channel, so that the assembled state is kept constant and stable, and the base 25 and the box 21 cannot slip off each other. A bottom button 251 is provided at each end of the pair of side edges 252, and the bottom button 251 is adapted to be engaged with a fixing member provided on the outside of the injector when the holding case 2 is mounted on the intraocular lens injector, thereby fixing the base 25 to the side of the injector, and a specific method of use will be described later. In the present embodiment, the bottom button 251 has two shapes and is formed in a T shape, but may be formed in any shape as long as it can be matched with a fixing member on the injector.

The holding case 2 is also provided with a case cover 24 having a top wall and four side walls, open at the bottom. In the process of preservation and transportation, the box cover 24 covers the box body 21 from the upper side, the bottom of the base 25 is clamped by utilizing the downward overturning of the side buckle 241 of the box cover 24, so that the box cover 24 and the base 25 assembled below the box body 21 are buckled into a whole to form a rectangular box body shown in the left diagram in fig. 4, and the box body is convenient to preserve and transport after sealed package. In this embodiment, two side buckles 241 are respectively connected to the sides of a pair of long sides, but the number and the arrangement positions may be changed according to the actual situation. Fig. 2 shows a schematic structural view of the back side of the cover 24. As shown in fig. 2, a pair of haptic positioning blocks 242 are further provided in the back surface of the cap 24 at positions corresponding to the bolus channel 215, the haptic positioning blocks 242 being formed as generally fan-shaped convex blocks whose shapes and positions match the positions of the intraocular lens 3 placed in the bolus channel 215, so that the haptic positioning blocks 242 are located just between the optical portion and the two haptic portions of the intraocular lens 3, ensuring that the intraocular lens 3 is positioned in a stretched flat state without causing the haptic portions and the optical portion to adhere to each other. While reducing the likelihood of relative displacement of the intraocular lens 3 due to shock experienced by the case 12 during transportation in individual packages.

As shown in fig. 1, the case 21 of the storage case 2 is further provided with a bracket 22, and the bracket 22 is slidably placed on a flat plate portion 211 of the case 21 to support the intraocular lens 3 from below. The details will be described below.

< Structure of bracket >

The structure of the bracket 22 is described in further detail below with reference to fig. 3. As shown in fig. 2, the bracket body 221 of the bracket 22 is formed in a frame structure of a shape of "コ" having two bracket arms parallel to each other; and the transverse frame part is perpendicular to the two supporting arms and connects one ends of the two supporting arms. A handle portion 222 is formed in the cross frame portion in the same plane as the cross frame portion for grasping by an operator to withdraw the carriage 22 during use. And a downward protrusion is formed at an end of the handle 222 so as to hang the bracket 22 in the case 21 so that it can be fixed in the case 21 without slipping off after being withdrawn. A slider portion 223 is provided on the lower side of the bracket arm of the bracket body 221, and the bracket 22 is slidably provided on the case 21 by fitting the slider portion 222 into the bracket groove 213. A positioning portion 224 is further provided on the upper side of the bracket arm of the bracket body 221 for positioning the intraocular lens 3 placed above the bracket arm so that the intraocular lens 3 does not slide in the direction of the grip portion 222.

Fig. 4 shows a bracket 22a as another example of the bracket structure. The bracket 22a has the same structure as the bracket main body 221, the slider portion 223, and the positioning portion 224 of the bracket 22, and a description thereof is omitted here. As a modification, the bracket 22a differs from the bracket 22 in that the handle portion 222a protrudes upward with respect to the bracket main body 221 as a whole, so that the operator can grasp more easily to pull backward. Like the handle portion 222 of the holder 22, a downward projection is formed at an end of the handle portion 222a so that the holder 22a is hung in the case 21 and is fixed to the case 21 so as not to slip off after being pulled out.

< Box Structure >

Fig. 5 shows a partial enlarged view of the case 21 in the preservation box 2. The structure of the case 21 will be described in further detail with reference to fig. 5.

A slope portion 212 is formed on the flat plate portion 211 of the case 21, and one end of the slope portion 212 is abutted against the inner wall 214 of the passage, and the other end is inclined upward at a certain angle (typically about 4 °, but not limited thereto) so as to protrude upward with respect to the flat plate portion 211 of the case 21. A pair of bracket grooves 213 are provided on both sides of the slope portion 212, the bracket grooves 213 penetrate the case 21, and one ends thereof abut against the inner wall 214, and are parallel to the longitudinal direction of the slope portion 212. The pair of bracket grooves 213 has a length shorter than that of the slope portion 212. The region formed by the ramp 212 and the bracket slot 213 is used for placing the bracket 22. In a state in which the intraocular lens 3 is held in the case 21, the holder main body 221 of the holder 22 is placed on the slope portion 212, and the pair of slider portions 223 is fitted into the holder groove 213 so that the holder 22 can freely slide along the extending direction of the holder groove 213. When the operator pulls the holder 22 rearward with the handle portion 222, the holder 22 is tilted up along the slope portion 212, eventually the handle portion 222 may hang at the protruding portion of the slope portion 212, keeping the holder 22 in a position away from the bolus channel 215, and disabling the holder 22 from moving in the direction of the bolus channel 215.

Two openings are also provided in the channel inner wall 214 for the support arms of the support 22 to pass through, and in the stored state of the intraocular lens, the two support arms of the support 22 extend into the bolus channel 215 through the channel inner wall 214, with the two support arms supporting the intraocular lens above the bolus channel 215. And in preparation for implantation of the intraocular lens, the carrier 22 is pulled back out of the bolus channel 215 so that the intraocular lens is released into the bolus channel 215. A stepped portion 219 having one end bent in an arc shape is formed at a position abutting against the channel outer wall 216, and the stepped portion 219 serves to limit the intraocular lens released into the bolus channel 215. The intraocular lens is not slid or shifted from the center position at will after being released, and can be kept at the position in the middle of the push channel 215 all the time, which contributes to the smooth implantation operation. In addition, two protruding points 217 are further arranged on the concave bottom surface of the push channel 215, and the two protruding points 217 are slightly protruded relative to the bottom surface of the push channel 215, so that the artificial crystal released into the push channel 215 is not completely contacted with the bottom surface of the push channel 215, the possibility of adhesion of the artificial crystal and the bottom surface of the push channel 215 is reduced, and the reliability of the push operation is improved.

< preservation State of intraocular lens preservation Box >

Fig. 6 shows the intraocular lens holding cartridge in a holding state. Wherein the left side is a schematic view of the snap-fit condition of the lid 24. In the storage state, the cover 24 covers the case body 21 from above, and the side button 241 of the cover 24 is turned down to engage with the bottom of the base 25. In the state where the cover 24 is engaged, the pair of side walls in the width direction extend to a position flush with the bottom surface of the case 21, and the pair of side walls in the length direction are positioned in contact with the side edges 252 of the base 25. And as described above, as shown in fig. 2, the haptic positioning block 242 provided on the back surface of the cover 24 is located just between the optical portion and the two haptics of the intraocular lens 3, ensuring that the intraocular lens 3 is positioned in a stretched flat state. Therefore, the box body 21 and the artificial lens 3 stored in the box body 21 are completely sealed in the closed space formed by the box cover 24 and the base 25, so that the box has good tightness and is favorable for storage and transportation. The right side view in fig. 6 shows a schematic view of the state in which the intraocular lens 3 is housed inside the case 21 in this stored state. As shown in this figure, inside the case 21 in the stored state, the holder 22 is fitted into the holder groove 213, and two holding arms are inserted into the bolus channel 215 through two openings on the channel inner wall 214, and the intraocular lens 3 is held from below so as to be located directly above the bolus channel 215. In the present embodiment, in the storage state, the positioning portion 224 of the bracket 22 is just located at the opening of the inner wall 214 of the channel, so that the positioning portion 224 and the inner wall 214 of the channel form a complete and non-notched side wall, and the tightness and structural integrity of the storage case 2 are further improved.

< method of implanting an intraocular lens Using an intraocular lens storage case >

A method of implanting an intraocular lens using the intraocular lens holding cartridge according to the present invention will be described below with reference to fig. 7.

For ease of transportation and storage, the present invention relates to an intraocular lens holding cartridge that is packaged separately from an intraocular lens injector. In preparation for intraocular lens implantation, the operator removes the injector and the holding cassette 2 from the package, respectively. The holding case 2 has been preloaded with an intraocular lens 3. First, the side button 241 of the lid 24 is opened, and the lid 24 is removed. Next, as shown in the left view of fig. 7, the storage case 2 is placed on the extension portion of the syringe, and two bottom buttons 251 provided at the front end of the base 25 are respectively engaged with the buttons 114 provided on both sides of the extension portion of the syringe, thereby fixing the base 25 to the outside of the case chamber 111 of the syringe. Thereafter, as shown in the middle diagram of fig. 7, the case 21 of the preservation box 2 is pushed, and the case 21 is pushed into the box cavity 111 of the injector along the extending direction of the side edge 252 of the base 25 by the sliding groove 218 until the outer wall 216 of the channel of the preservation box 2 abuts against the inner wall of the barrel 11 of the injector, at this time, the injecting channel 215 is located at the center of the barrel 11, and the intraocular lens 3 is located on the center axis of the length direction of the barrel 11. Then, the cavity cover 112 of the injector is turned downwards to be matched and jogged with the groove arranged on the inner wall 214 of the channel in the preservation box 2, so that the cavity cover 112 is abutted against the inner wall 214 of the channel to form a sealing state. Here, the cavity cover 112 is omitted in the right drawing of fig. 7 for convenience of the following description. After the cavity cover 112 is engaged, as shown in the right diagram of fig. 7, the support arm of the bracket 22 is located inside the box cavity 111 and supports the intraocular lens 3 from below, and the handle 222 of the bracket 22 is located outside the box cavity 111, i.e., is not engaged inside the box cavity 111 by the cavity cover 112. At this time, the operator pulls the carriage 22 along the slope portion 212 to the outside of the cassette chamber 111 by the handle portion 222. While the trailing arm of the carrier 22 is pulled back through the opening in the channel inner wall 214, the intraocular lens 3 is blocked in the bolus channel 215 by the channel inner wall 214. Eventually the carrier 22 is completely withdrawn from the bolus channel 215 and the intraocular lens 3 is released into the bolus channel 215. The holding cassette 2 is thus mounted, and the intraocular lens 3 is ready for bolus injection.

Next, the pressing block of the injector is pressed into the capsule 111, and the intraocular lens 3 is preloaded by the pressing column of the pressing block to be in an upwardly bent state.

Because of the intraocular lens injector used in the present invention, the plunger of the injector has been loaded into the barrel 11 in a state to be pushed. Thus, after the intraocular lens 3 has been loaded and preloaded as described above, the pushing rod is pushed so that the tip of the pushing rod just touches the lateral midpoint of the intraocular lens 3, and the intraocular lens 3 is pushed into the front nozzle of the injector 1 along the injection channel 215. Along with the pushing of the push rod 13, the intraocular lens 3 is gradually pushed to the outlet of the anterior nozzle, the inner wall of the anterior nozzle gradually narrows to form a pressing force on the intraocular lens 3 to further curl the intraocular lens, the intraocular lens is completely rolled up when reaching the outlet, and finally the intraocular lens is pushed out from the outlet of the anterior nozzle 12 to the eye incision, and implantation is completed.

The intraocular lens storage box is suitable for the intraocular lens injector with the box cavity capable of being filled with the storage box, and the manual intraocular lens filling operation is replaced by directly filling the storage box, so that the operation procedure of filling the intraocular lens into the injector is greatly simplified, and the requirements on the proficiency of operators are also greatly reduced. Thereby ensuring shorter loading time of the artificial lens and lower risk of unnecessary damage to the artificial lens, and ensuring better operability of the artificial lens injector.

And, since the present invention employs the extractable support structure placed inside the preservation box as described above. Therefore, the structure of the artificial crystal preservation box is more compact, the shape of the box is simpler and more regular, and the artificial crystal preservation box is more convenient to package, preserve and transport.
