Description

Technical Field

[0001] This utility model relates to the field of ophthalmic medical device technology, and in particular to a cotton swab. Background Technology

[0002] ICL (Implantable Collamer Lens) is a special type of artificial lens used to correct vision. ICL surgery is an ophthalmic procedure used to correct refractive errors such as myopia, hyperopia, and astigmatism. During the surgery, an ICL lens is implanted inside the eye to improve vision. These artificial lenses are mainly divided into hydrophilic and hydrophobic types. Hydrophilic artificial lenses are stored in a borosilicate glass vial containing a storage solution. During the surgery, the artificial lens is removed from the vial using a cotton swab.

[0003] In related technologies, the cotton tip of the cotton swab lacks support for the intraocular lens, making it difficult for the cotton swab to smoothly remove the intraocular lens from the reagent bottle. The process of removing the intraocular lens takes a long time, thus prolonging the surgical preparation time. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a cotton swab that can shorten the time required to remove an artificial lens.

[0005] The cotton swab according to a first aspect of the present invention includes: The cotton swab body has a first end and a second end arranged along the length direction of the cotton swab body; A cotton tip is connected to the first end of the cotton swab body.

The first opening is opposite to the bottom wall of the receiving groove, the second opening is located on the side wall of the receiving groove, and the first groove wall is used to abut against the artificial lens to hold the artificial lens within the receiving groove. The cotton swab according to this embodiment of the present invention has at least the following beneficial effects: In this embodiment, the cotton swab has a receiving groove, and the sidewall of the receiving groove has a second opening and a first groove wall for supporting the intraocular lens. When the cotton swab is inserted into the reagent bottle, the cotton tip comes into contact with the water in the reagent bottle. After absorbing water, the cotton tip expands, and the receiving groove gradually increases in size. The operator can hold the cotton swab body to bring the cotton tip close to the intraocular lens. After the receiving groove touches the intraocular lens, the liquid in the receiving groove can flow out of the receiving groove through the second opening, allowing the cotton swab to easily guide the intraocular lens from the first and second openings into the receiving groove. The first groove wall of the receiving groove supports the intraocular lens, allowing it to be moved out of the reagent bottle more stably with the cotton tip, shortening the preparation time for surgery. Furthermore, the receiving groove can enclose the intraocular lens, which can reduce interference between the intraocular lens and the reagent bottle wall to a certain extent, thereby reducing the likelihood of scratches on the surface of the intraocular lens.

[0006] According to some embodiments of the present invention, there are multiple receiving slots, and the multiple receiving slots are arranged at intervals along the circumference of the cotton head.

[0007] According to some embodiments of the present invention, the thickness of the cotton head gradually increases along the direction from the second end toward the first end.

[0008] According to some embodiments of the present invention, the opening size of the receiving groove gradually decreases along the direction from the second end toward the first end.

[0009] According to some embodiments of the present invention, the cotton head has a dry state and a saturated state, and the cotton head is configured to switch from the dry state to the saturated state after absorbing water, and the volume of the cotton head increases when it is in the saturated state.

[0010] According to some embodiments of this utility model, the cotton head is made of polyvinyl alcohol.

[0011] According to some embodiments of the present invention, when the cotton head is saturated, the contour line of the receiving groove away from the second end is the first contour line, and the first contour line is an arc.

[0012] According to some embodiments of the present invention, the receiving groove further includes a second groove wall and a third groove wall arranged opposite to each other along a first direction. The second groove wall and the third groove wall form the groove opening. The second groove wall and the third groove wall are respectively connected to the first groove wall. When the cotton head is saturated, when projected along the first direction, the projection area of ​​the receiving groove has a second contour line on the side away from the axial direction of the cotton swab body. The angle between the second contour line and the axial direction of the cotton swab body is in the range of 15°~25°.

[0013] According to some embodiments of the present invention, the cotton swab body includes a gripping member and a clamping member connected to each other, the first end is located at the clamping member, the second end is located at the gripping member, the clamping member has a clamping groove, and the cotton head is partially clamped by the clamping groove.

[0014] According to some embodiments of the present invention, the cotton swab body protrudes circumferentially to form a limiting portion, and along the length direction of the cotton swab body, the distance between the limiting portion and the second end is less than the distance between the limiting portion and the first end.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] In related techniques, the intraocular lens (IOL) is placed inside a reagent bottle with a small opening. Typically, during surgery, the operator uses a cotton swab to remove the IOL from the bottle. The cotton swab tip is usually spherical, while the IOL is a soft, sheet-like structure. During removal, the cotton swab may rub against the bottle wall, potentially scratching the IOL. Furthermore, the spherical cotton tip cannot adequately support the IOL, making it prone to detaching and falling back into the bottle during removal. This time-consuming process can negatively impact the surgical procedure.

[0027] In this embodiment, the cotton head 200 has a receiving groove 200a, and the receiving groove 200a has a first groove wall 200c on the side opposite to the second end 100b. After the cotton head 200 is hydrated by water, the receiving groove 200a will expand, thereby enabling the first groove wall 200c to support the artificial lens, and the artificial lens can be moved out of the reagent bottle relatively smoothly with the cotton head 200.

[0028] The first aspect of this application provides a cotton swab; please refer to [link / reference needed]. Figure 1 , Figure 3 and Figure 7The cotton swab includes a swab body 100 and a cotton tip 200. The swab body 100 has a first end 100a and a second end 100b arranged along the length of the swab body 100. The swab body 100 is a rod-shaped structure, with the first end 100a and the second end 100b being the two ends of the rod-shaped structure. The cotton tip 200 is connected to the first end 100a of the swab body 100 and has a receiving groove 200a. The receiving groove 200a has a first opening 200h, a second opening 200b, and a first groove wall 200c. The first opening 200h is disposed opposite to the bottom wall of the receiving groove 200a, the second opening 200b is located on the side wall of the receiving groove 200a, and the first groove wall 200c is used to abut against the intraocular lens to hold the intraocular lens within the receiving groove 200a.

[0029] In the embodiment of this application, the cotton swab 200 has a receiving groove 200a, and the sidewall of the receiving groove 200a has a second groove opening 200b and a first groove wall 200c for supporting the artificial lens. When the cotton swab is inserted into the reagent bottle, the cotton swab tip 200 will come into contact with the water in the reagent bottle. After the cotton swab tip 200 absorbs water and becomes hydrated, it expands upon contact with water, and the receiving groove 200a gradually increases in size. The operator can hold the cotton swab body 100 to bring the cotton tip 200 close to the intraocular lens. After the receiving groove 200a touches the intraocular lens, the liquid in the receiving groove 200a can flow out of the receiving groove 200a through the second groove 200b, allowing the cotton swab to easily move the intraocular lens from the first groove 200h and the second groove 200b into the receiving groove 200a. The first groove wall 200c of the receiving groove 200a can support the intraocular lens, allowing it to be moved more stably out of the reagent bottle along with the cotton tip 200, shortening the preparation time for surgery. Furthermore, the receiving groove 200a can wrap around the intraocular lens, which can reduce the interference between the intraocular lens and the reagent bottle wall to a certain extent. Also, with the cotton tip wrapping around the intraocular lens, friction between the cotton swab body and the intraocular lens can be reduced, thus reducing the likelihood of scratches on the surface of the intraocular lens.

[0030] In one embodiment, there are multiple receiving grooves 200a, which are arranged at intervals along the circumference of the cotton head 200.

[0031] For example, please refer to Figure 10 There are two accommodating cavities, which are symmetrically arranged along the central axis of the cotton swab body 100.

[0032] In the embodiment of this application, there are multiple receiving slots 200a. When the operator holds the cotton swab body 100 and inserts it into the reagent bottle, the multiple receiving slots 200a enable the operator to select the closest receiving slot 200a to the artificial lens based on the current position of the artificial lens. This reduces the need for the operator to rotate multiple times to adjust the angle of the cotton head 200 in order to pick up the artificial lens, thereby further reducing the time spent by the operator in picking up the artificial lens.

[0033] It is understood that other embodiments of this application do not limit the number of receiving slots 200a.

[0034] In one embodiment, please refer to Figure 4 and Figure 5 The direction from the second end 100b to the first end 100a is a unidirectional direction, and the direction from the second end 100b to the first end 100a is a second direction, as shown in the example below. Figure 2 As indicated by the middle arrow R2, the second direction is parallel to the length direction of the cotton swab body 100. Along the direction from the second end 100b towards the first end 100a, the thickness of the cotton head 200 gradually increases. This gradual increase in thickness along the second direction allows the side of the cotton head 200 away from the second end 100b to be larger after absorbing water and expanding, resulting in a deeper receiving groove 200a. This better supports the artificial lens and further reduces the possibility of the artificial lens dislodging during removal.

[0035] It is understood that other embodiments of this application are not limited to a gradual increase in thickness of the cotton head 200 along the direction from the second end 100b toward the first end 100a. Exemplarily, the thickness of the cotton head 200 remains constant along the direction from the second end 100b toward the first end 100a.

[0036] In one embodiment, please refer to Figure 1 and Figure 2Along the direction from the second end 100b towards the first end 100a, the opening size of the receiving groove 200a gradually decreases. The opening size of the receiving groove 200a refers to the distance between the opposing groove walls of the receiving groove 200a. The opening size of the receiving groove 200a gradually decreases, meaning that the second opening 200b of the receiving groove 200a is the largest opening of the receiving groove 200a, and the opposing groove walls of the receiving groove 200a gradually move closer together along the first direction. Projecting along a direction parallel to the plane containing the second opening 200b and the plane containing the groove walls, the shape of the projected area of ​​the receiving groove 200a is trapezoidal. The smaller opening on the side of the receiving groove 200a away from the second end 100b allows the area of ​​the first groove wall 200c to be as large as possible when the cotton head 200 is saturated. This enables better pickup of the artificial crystal from the reagent bottle and increases the contact area between the artificial crystal and the first groove wall 200c, reducing the likelihood of the artificial crystal detaching from the cotton head 200.

[0037] It is understood that other embodiments of this application do not limit the opening size of the receiving groove 200a to gradually decrease along the direction from the second end 100b toward the first end 100a. Exemplarily, the opening size of the receiving groove 200a remains constant along the direction from the second end 100b toward the first end 100a.

[0038] In one embodiment, the cotton head 200 has a dry state and a saturated state. The cotton head 200 is configured to switch from the dry state to the saturated state after absorbing water, and the volume of the cotton head 200 increases in the saturated state. When the cotton head 200 switches from the dry state to the protective state, the volume of the receiving groove 200a increases, and the area of ​​the first groove opening 200h and the second groove opening 200b of the receiving groove 200a also increases, further reducing the difficulty for the artificial lens to enter the receiving groove 200a, and the receiving groove 200a provides better support for the artificial lens.

[0039] In one embodiment, the cotton tip 200 is made of polyvinyl alcohol. The cotton tip 200 is made of PVA (Polyvinyl alcohol fiber), which has a smooth surface and whose fibers are less prone to detachment. During the process of immersing the cotton tip 200 in the reagent bottle, the fibers are less likely to remain on the surface of the artificial lens, resulting in better surgical outcomes. Furthermore, PVA has good water absorption and a high water absorption rate, allowing it to expand quickly upon contact with water, thereby facilitating the pickup of the artificial lens and further reducing the pickup time.

[0040] It is understood that other embodiments of this application do not limit the material of the cotton head 200. For example, the material of the cotton head 200 may be cotton.

[0041] In one embodiment, please refer to Figures 7 to 9The material of the cotton tip 200 is absorbent; when it comes into contact with water, it absorbs moisture and expands. The saturated state of the cotton tip 200 refers to the state where it can no longer absorb more moisture after absorbing a portion. When the cotton tip 200 is saturated, the outline of the receiving groove 200a away from the second end 100b is the first outline 200d, which is an arc. Since the artificial lens is a soft, sheet-like structure, with the receiving groove 200a supporting the artificial lens, the contact area between the arc-shaped first outline 200d and the artificial lens is relatively large, allowing the first outline 200d to provide better support for the artificial lens.

[0042] It is understood that other embodiments of this application do not limit the shape of the first contour line 200d. Exemplarily, the first contour line 200d is a straight line segment.

[0043] In one embodiment, please refer to Figures 7 to 9 The receiving tank 200a further includes a second tank wall 200e and a third tank wall 200f arranged opposite to each other along a first direction. The first direction is as follows: Figure 9 The direction indicated by the middle arrow R1. The first groove wall 200c, the second groove wall 200e, and the third groove wall 200f together enclose a receiving groove 200a. Both the second groove wall 200e and the third groove wall 200f are connected to the first outline 200d. The second groove wall 200e and the third groove wall 200f enclose a second opening 200b, and both the second groove wall 200e and the third groove wall 200f are respectively connected to the first groove wall 200c. Along the direction from the second end 100b towards the first end 100a, the second groove wall 200e gradually shifts towards the direction closer to the third groove wall 200f, and the third groove wall 200f gradually shifts towards the direction closer to the second groove wall 200e. The second groove wall 200e and the third groove wall 200f move closer to each other, thus gradually reducing the opening of the receiving groove 200a. Please refer to [link to relevant documentation]. Figure 10 and Figure 11When the cotton head 200 is saturated, projected along the first direction, the projection area of ​​the receiving groove 200a has a second contour line 200g on the side opposite to the axial direction of the cotton swab body 100. The angle between the second contour line 200g and the axial direction of the cotton swab body 100 ranges from 15° to 25°. The second contour line 200g is a straight line and is connected to the first contour line 200d. Projected along the first direction, the projection area of ​​the second groove wall 200e coincides with the projection area of ​​the third groove wall 200f. The axial direction of the cotton swab body 100 is arranged parallel to the length direction of the cotton swab body 100. The angle between the second contour line 200g and the axial direction of the cotton swab body 100 is within a suitable range, which allows the receiving groove 200a to be as large as possible, thereby better supporting the artificial lens. It also allows the first contour line 200d of the first groove wall 200c to be close to the artificial lens, so that the artificial lens can enter the receiving cavity along the first contour line 200d. Because the opening of the reagent bottle is small, the range of movement that the operator can make while moving the cotton swab is limited. When the angle between the second contour line 200g and the axis of the cotton swab body 100 is large, the first contour line 200d of the first groove wall 200c may have difficulty contacting the bottom surface of the artificial lens.

[0044] For example, projected along the first direction, the angle between the second contour line 200g and the axial direction of the cotton swab body 100 is 15°, 17°, 20°, 23°, or 25°. The angle between the second contour line 200g and the axial direction of the cotton swab body 100 is as follows: Figure 11 The midpoint angle θ1 is shown.

[0045] For example, the first direction and the second direction are arranged orthogonally.

[0046] It is understood that other embodiments of this application do not limit the size of the angle between the second contour line 200g and the axial direction of the swab body 100.

[0047] In one embodiment, please refer to Figure 6 , Figure 10 and Figure 11The cotton swab body 100 includes a gripper 110 and a clamping member 120 connected to each other. A first end 100a is located on the clamping member 120, and a second end 100b is located on the gripper 110. The cotton swab body 100 is a one-piece molded structure. The operator can move or rotate the cotton swab by holding the gripper 110, so that the cotton tip 200 gradually approaches the intraocular lens, thereby allowing the intraocular lens to slide into the receiving groove 200a. The clamping member 120 has a clamping groove 120a, and the cotton tip 200 is partially clamped by the clamping groove 120a. The cotton tip 200 and the clamping member 120 are clamped and connected through the clamping groove 120a. The connection strength between the cotton tip 200 and the clamping member 120 is high, which can reduce the possibility of the cotton tip 200 detaching from the cotton swab body 100. Exemplarily, the clamping member 120 is partially visible to the outside through the receiving groove 200a.

[0048] It is understood that other embodiments of this application do not limit the connection method between the cotton swab body 100 and the cotton tip 200. Exemplarily, the cotton tip 200 and the cotton swab body 100 are bonded together.

[0049] In one embodiment, please refer to Figure 11 The clamping groove 120a penetrates the clamping member 120, and the accommodating groove 200a is arranged orthogonally to the extension direction of the clamping member 120. The clamping member 120 and the accommodating groove 200a are mutually adapted, and the groove wall of the clamping groove 120a has a small obstructive effect on the expansion process of the accommodating groove 200a. The extension direction of the clamping groove 120a is parallel to the first direction, and the arrangement direction of the clamping member 120 and the accommodating groove 200a is a third direction, which is orthogonal to both the first and second directions. Figure 10 The direction indicated by the middle arrow R3. The clamping groove 120a can limit the expansion of the cotton head 200 in the third direction. After the cotton head 200 comes into contact with water, it expands and can easily form a receiving groove 200a at the clamping member 120, so that the receiving groove 200a can pick up the artificial lens. Furthermore, the clamping member 120 can provide a certain degree of support for the cotton head 200, reducing the possibility that the cotton head 200 will deform significantly due to the decrease in stiffness caused by contact with water, thus preventing the artificial lens from detaching from the cotton head 200.

[0050] In one embodiment, please refer to Figure 5The opening size of the end of the clamping groove 120a facing the second end 100b is larger than the opening size of the end of the clamping groove 120a away from the second end 100b. The smaller opening end of the clamping groove 120a can clamp the cotton head 200, so that after the cotton head 200 expands when it comes into contact with water, both sides of the smaller opening end will expand to a certain extent, thereby squeezing the smaller opening end and reducing the possibility of the cotton head 200 detaching from the cotton swab body 100 when it expands.

[0051] In one embodiment, please refer to Figure 1 The cotton swab body 100 has a circumferentially protruding limiting portion 100c. The limiting portion 100c is approximately spherical in shape and is formed on the gripper 110. Along the length of the cotton swab body 100, the distance between the limiting portion 100c and the second end 100b is less than the distance between the limiting portion 100c and the first end 100a. When the operator holds the cotton swab body 100 to pick up the intraocular lens, the finger may continuously adjust its position along the length of the cotton swab body 100. When the finger touches the limiting portion 100c, which is close to the second end 100b, it can remind the operator that the current position of the finger is close to the second end 100b, thereby reducing the chance of the operator's finger detaching from the second end 100b of the cotton swab body 100.

[0052] In one embodiment, please refer to Figure 1 The cotton swab body 100 also has an anti-slip part 100d, which is located between the limiting part 100c and the first end 100a along the length direction of the cotton swab body 100. Projected along the length direction of the cotton swab body 100, the projection area of ​​the anti-slip part 100d is a regular hexagon. When the operator holds the anti-slip part 100d with their fingers, the rotation angle of the cotton swab body 100 can be adjusted in stages by rotating the anti-slip part 100d, and the occurrence of the fingers slipping off the cotton swab body 100 can be reduced to a certain extent.

[0053] In one embodiment, please refer to Figure 12 The cotton swab also includes a protective sleeve 300, which is fitted onto the cotton tip 200 and the main body 100 of the cotton swab. The protective sleeve 300 can provide some protection for the cotton tip 200, reducing the possibility of the cotton tip 200 detaching from the main body 100 of the cotton swab due to external forces during the transportation of the cotton swab.

[0054] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of protection.
