Description

Intraocular lens storage case and method of implanting intraocular lens
Technical Field
The present invention relates to an intraocular lens storage case in which an intraocular lens is pre-loaded and to a method of implanting an intraocular lens using the same.
Background
An intraocular lens (IOL) is an artificial lens that is implanted in a human eye to replace the natural crystalline lens in order to correct refractive errors of the eye when the eye has cataracts or other diseases. Because the intraocular lens is made of flexible materials and has small size, the intraocular lens is difficult to directly carry out surgical operation, and therefore an auxiliary medical instrument needs to be implanted into the eye through a minimally invasive surgery opening.
The conventional intraocular lens implantation system is composed of an aircraft head and an implanter body. During the operation, the intraocular lens, which is packaged separately, is taken out of the package by the medical staff and loaded into the injector for implantation and then implanted. There is a large uncertainty factor since the loading process is completely dependent on the skill of the medical practitioner in the procedure. If the operating staff is less skilled, the operation time may be prolonged greatly, and even the artificial lens may be damaged artificially. Moreover, different operators may cause different loading states (loading angles, etc.) of the intraocular lens, which is prone to cause misoperation, so that the state of the intraocular lens after being pushed into the eye is poor (in extreme cases, the front and the back may be reversed), 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 can reduce the operational difficulty of the implantation process, so that the process is not affected by the skill of the operator, to ensure that the implantation state of the intraocular lens is always good.
One preloaded intraocular lens injector disclosed in patent document 1 includes a holder, the holder and IOL being removably mounted to the injector body and sealed in the same package for delivery to a surgeon. The retainer and IOL are connected together and sealed in one package, the injector body is sealed in a separate package, and the surgeon attaches 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 release from the retainer and seat in an unstressed state in the injector body. The compressor is moved to the 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 thence out into the eye.

< Structure of intraocular lens storage case >
Fig. 1 is a schematic view showing the construction of an intraocular lens storage case according to the present invention. As shown in fig. 1, the storage case 2 includes a case body 21, and the case body 21 has a flat plate portion 211 formed in a flat plate shape. A push channel 215 is provided at one end of the cartridge body 21, and the push channel 215 is formed as an arc channel with a bottom surface recessed downward. A channel outer wall 216 is formed on one side of the bolus channel 215 far away from the flat plate portion 211, and a channel inner wall 214 is formed on one side adjacent to the flat plate portion 211, wherein the height of the channel inner wall 214 is slightly lower than that of the channel outer wall 216. A pair of slide grooves 218 are formed on both sides of the flat plate portion 211 of the case 21 in the longitudinal direction, and the length of the slide grooves 218 is shorter than the length of the flat plate portion 211 of the case 21.
The storage case 2 further includes a base 25, wherein the base 25 has a pair of side edges 252 at both sides thereof, and a groove is formed inside the side edges 252 for the sliding groove 218 of the case body 21 to slide therein, so that the case body 21 is assembled with the base 25 in a freely slidable manner. As shown in fig. 1, the side 252 is further provided with a side stopper 253, when the box body 21 and the base 25 are assembled, the side stopper 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 body 21 cannot slip off from each other. A bottom buckle 251 is provided at each of the pair of side edges 252, and the bottom buckle 251 is adapted to be engaged with a fixing member provided at the outer side of the injector when the storage case 2 is mounted on the injector for intraocular lens, so as to fix the base 25 to the side of the injector. In this embodiment, the bottom buckle 251 has two parts and is formed in a T shape, but may be formed in any shape as long as it can match with a fixing member on the injector.
The storage case 2 further includes a case cover 24 having a top wall and four side walls, and an opening at the bottom. In the process of storage and transportation, the box cover 24 covers the box body 21 from the upper part, the edge buckle 241 of the box cover 24 is turned downwards to clamp the bottom of the base 25, so that the box cover 24 and the base 25 assembled below the box body 21 are buckled and integrated into a whole to form a rectangular box body shown in the left figure of fig. 4, and the rectangular box body is convenient to store and transport after being sealed and packaged. In this embodiment, two side buckles 241 are provided and connected to the sides of the pair of long sides, respectively, but the number and the installation position may be changed according to the actual situation. Fig. 2 shows a schematic view of the back of the cover 24. As shown in fig. 2, a pair of haptic positioning blocks 242 is further provided in the back surface of the cap 24 at positions corresponding to the push-in channel 215, and the haptic positioning blocks 242 are formed as substantially fan-shaped convex blocks whose shape and position match the position of the intraocular lens 3 placed in the push-in channel 215, so that the haptic positioning blocks 242 are positioned just between the optical portion and both haptics of the intraocular lens 3, ensuring that the intraocular lens 3 is positioned in a stretched flat state without the haptics and the optical portion adhering to each other. While reducing the likelihood of relative displacement of the intraocular lens 3 due to shocks to which the cartridge 12 is subjected during transport in the individual packages.
As shown in FIG. 1, the case body 21 of the storage case 2 is further provided with a bracket 22, and the bracket 22 is placed on the flat plate portion 211 of the case body 21 in a back-and-forth slidable manner for supporting the intraocular lens 3 from below. The details will be described later.
< bracket Structure >
The structure of the bracket 22 will be 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 "コ" shape, having two bracket arms parallel to each other; and the transverse frame part is perpendicular to the two support arms and connects one end of each of the two support arms. The lateral frame portion is formed with a handle portion 222, which is formed on the same plane as the lateral frame portion, and which is gripped by an operator to draw out the bracket 22 when the operator uses the device. And a downward protrusion is formed at the end of the handle portion 222 so that the bracket 22 can be hung in the box body 21 and fixed in the box body 21 without slipping after being drawn out. A slider 223 is provided on the lower side of the bracket arm of the bracket body 221, and the bracket 22 is slidable on the case 21 by fitting the slider 222 into the bracket groove 213. A positioning portion 224 for positioning the intraocular lens 3 placed above the holder arm so that the intraocular lens 3 does not slide in the direction of the grip portion 222 is further provided on the upper side of the holder arm of the holder main body 221.
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 description thereof is omitted. As a modification, the bracket 22a is different from the bracket 22 in that the entire handle portion 222a protrudes upward relative to the bracket main body 221, making it easier for the operator to grasp for pulling backward. Similarly to the pull portion 222 of the bracket 22, a downward protruding strip is formed at an end of the pull portion 222a so that the bracket 22a can be hung in the box body 21 and fixed in the box body 21 without slipping after being pulled out.
< Box Structure >
Fig. 5 shows a partially enlarged view of the box body 21 in the storage 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 body 21, one end of the slope portion 212 abuts against the channel inner wall 214, and the other end thereof is inclined upward at a certain angle (generally, but not limited to, about 4 °) so as to protrude upward with respect to the flat plate portion 211 of the case body 21. A pair of bracket slots 213 are formed on both sides of the slope 212, the bracket slots 213 penetrate the case body 21, and one end thereof abuts against the inner wall 214 of the passage in parallel with the longitudinal direction of the slope 212. The length of the pair of bracket slots 213 is shorter than the length of the ramp portion 212. The area of the ramp 212 and bracket slot 213 is used to place the bracket 22. In a state where 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 are fitted into the holder grooves 213 so that the holder 22 can slide freely along the extending direction of the holder grooves 213. When the operator pulls the carriage 22 backward using the pull portion 222, the carriage 22 tilts up along the ramp portion 212, and eventually the pull portion 222 may hang at the protruding portion of the ramp portion 212, keeping the carriage 22 away from the bolus channel 215, and preventing the carriage 22 from moving in the direction of the bolus channel 215.
Two openings are also provided in the channel inner wall 214 for the passage of the holder 22, and in the storage state of the intraocular lens, the two holders of the holder 22 extend through the channel inner wall 214 into the bolus channel 215, and the intraocular lens is supported above the bolus channel 215 by means of the two holders. When the intraocular lens is to be implanted, the holder 22 is pulled back out of the bolus channel 215 so that the intraocular lens is released into the bolus channel 215. A step 219 having one end bent in a circular arc shape is formed at a position close to the channel outer wall 216, and the step 219 serves to limit the intraocular lens discharged into the bolus channel 215. The intraocular lens can not slide or shift from the central position randomly after being released, and can be kept at the central position of the push injection channel 215 all the time, which is helpful for the smooth implantation operation. In addition, two salient points 217 are arranged on the bottom surface of the concave pushing injection channel 215, and the two salient points 217 are slightly raised relative to the bottom surface of the pushing injection channel 215, so that the intraocular lens released into the pushing injection channel 215 cannot be completely contacted with the bottom surface of the pushing injection channel 215, the possibility of adhesion of the intraocular lens and the bottom surface of the pushing injection channel 215 is reduced, and the reliability of pushing injection operation is improved.
< storage State of intraocular lens storage case >
Fig. 6 shows the intraocular lens storage case in a storage state. The left figure is an appearance schematic diagram of the buckling state of the box cover 24. In the storage state, lid 24 covers box 21 from above, and edge buckle 241 of lid 24 is turned downward and engaged with the bottom of 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 body 21, and the pair of side walls in the length direction are positioned in contact with the side edges 252 of the base 25. Also, as described above, the haptic positioning block 242 provided on the back surface of the cap 24 is positioned just between the optic and both haptics of the intraocular lens 3 as shown in fig. 2, ensuring that the intraocular lens 3 is positioned in a stretched flat state. Therefore, the case body 21 and the intraocular lens 3 stored in the case body 21 are completely sealed in the sealed space formed by the case cover 24 and the base 25, and the case has good sealing performance and is beneficial to storage and transportation. The right drawing in fig. 6 shows a schematic view of a state in which the intraocular lens 3 is loaded inside the case body 21 in this stored state. As shown in this figure, in the case 21 in the storage state, the holder 22 is inserted into the holder slot 213, and the two holder arms extend into the bolus channel 215 through the two openings in the channel inner wall 214, and hold the intraocular lens 3 from below so as to be positioned directly above the bolus channel 215. In addition, in the 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 unnotched side wall, and the sealing performance and the structural integrity of the storage box 2 are further improved.
< method for implanting intraocular lens using intraocular lens storage case >
A method of implanting an intraocular lens using the intraocular lens storage case according to the present invention will be described with reference to FIG. 7.
The present invention relates to an intraocular lens storage case that is packaged separately from an intraocular lens injector for ease of shipping and storage. In preparation for intraocular lens implantation, the operator takes the injector and the holding case 2 out of the package, respectively. The storage case 2 has an intraocular lens 3 already preloaded therein. First, the edge buckle 241 of the box cover 24 is opened, and the box cover 24 is removed. Next, as shown in the left side of fig. 7, the storage case 2 is placed on the extension of the syringe, and the two bottom fasteners 251 provided at the front end of the base 25 are respectively engaged with the fasteners 114 provided at both sides of the extension of the syringe, thereby fixing the base 25 outside the case cavity 111 of the syringe. Then, as shown in the middle view of fig. 7, the case body 21 of the storage case 2 is pushed, and the case body 21 is pushed into the case cavity 111 of the injector along the extending direction of the side 252 of the base 25 by the sliding groove 218 until the channel outer wall 216 of the storage case 2 abuts against the inner side wall of the barrel 11 of the injector, at this time, the injection channel 215 is located at the center of the barrel 11, and the intraocular lens 3 is located on the central axis of the length direction of the barrel 11. Next, the cavity cover 112 of the injector is turned downward and fitted into a groove provided in the inner wall 214 of the passage in the storage case 2, so that the cavity cover 112 abuts against the inner wall 214 of the passage to form a sealed state. Here, the chamber cover 112 is omitted in the right drawing of fig. 7 for convenience of the following description. As shown in the right view of FIG. 7, after the cover 112 is fastened, the bracket arm of the bracket 22 is located inside the cavity 111 and supports the intraocular lens 3 from below, and the pull handle 222 of the bracket 22 is located outside the cavity 111, i.e., is not fastened inside the cavity 111 by the cover 112. At this time, the operator pulls out the carriage 22 along the slope portion 212 to the outside of the cartridge chamber 111 by using the handle portion 222. While the holder arm of the holder 22 is drawn back through the opening in the channel inner wall 214, the intraocular lens 3 is retained by the channel inner wall 214 in the bolus channel 215. Eventually the carrier 22 is completely withdrawn from the bolus channel 215 and the intraocular lens 3 is released into the bolus channel 215. By this time the mounting of the holding case 2 is completed, the intraocular lens 3 is ready for bolus injection.
The plunger of the plunger is then pushed down to press it into the cavity 111, and the intraocular lens 3 is pre-pressed by the plunger of the plunger to be bent upward.
Due to the intraocular lens injector used in the present invention, the plunger of the injector is already loaded into the barrel 11 and is in a ready-to-inject state. Therefore, after the intraocular lens 3 has been loaded to completion and the pre-compression is completed as described above, the intraocular lens 3 is pushed into the front mouth of the injector 1 along the injection channel 215 by pushing the push rod so that the tip end of the push rod just touches the lateral midpoint of the intraocular lens 3. The intraocular lens 3 is gradually pushed to the outlet of the front mouth along with the pushing of the pushing rod 13, the inner wall of the front mouth gradually narrows to form a pressing force on the intraocular lens 3 so that the intraocular lens is further curled, and the intraocular lens is completely curled when reaching the outlet and is finally pushed out from the outlet of the front mouth 12 to the eye incision, and the implantation is completed.
The intraocular lens storage box is suitable for the intraocular lens injector with the box cavity in which the storage box can be arranged, and the storage box is directly arranged to replace the manual operation of arranging the intraocular lens, so that the operation procedure of arranging the intraocular lens into the injector is greatly simplified, and the requirement on the proficiency of operators is greatly reduced. Thereby ensuring that the intraocular lens loading time is short and the risk of causing unnecessary damage to the intraocular lens is low, and making the operability of the intraocular lens injector more excellent.
Also, since the present invention employs the extractable bracket structure disposed inside the preservation box as described above. Therefore, the structure of the intraocular lens storage box is more compact, the shape of the box body is simpler and more regular, and the intraocular lens storage box is more convenient to package, store and transport.
