Description

Technical Field

[0001] This utility model relates to the field of implants, and more specifically, to an integrated punctal plug implant expander. Background Technology

[0002] Dry eye syndrome, also known as keratoconjunctivitis sicca, is a common and complex ophthalmic disease caused by insufficient tear secretion, excessive evaporation, or abnormal tear composition. It can lead to eye discomfort and visual impairment. Papillary punctum occlusion is one of the most common treatments for dry eye syndrome. Papillary punctum plugs are implanted to restrict tear drainage through the lacrimal duct using either non-penetrating or penetrating plugs, thereby increasing the amount of natural tears that lubricate the ocular surface. This treatment can effectively relieve dry eye symptoms long-term. Currently, commonly used papillary punctum plug implants include... Figure 1 , Figure 2 The two models shown are: Model 1 and Model 2. Model 1 has a one-piece punctum plug dilator, with one end being the punctum plug implanter and the other end being the punctum dilator. When using it, the punctum is first dilated using the punctum dilator, and then the two ends of the instrument are reversed and inserted back into the punctum to insert the punctum plug. Model 2 has a punctum plug dilator implanter that can be manually disassembled into two parts, namely the implanter and the dilator. The usage method is the same as that of Model 1.

[0003] A search revealed that Chinese Patent Publication No. CN119015045A discloses a "Tear punctum plug dilator implanter," comprising a housing with a through hole at one end, a dilator rod moving groove on the side of the housing at one end of the through hole, a removable dilator rod within the dilator rod moving groove, a dilator rod with a dilator tip adapted to the through hole at one end, and a dilator rod moving groove on the side of the housing away from the through hole. An implantation rod is slidably mounted within the housing, and a sliding button is provided on the implantation rod corresponding to the position of the dilator rod moving groove. The sliding button is slidably connected within the dilator rod moving groove. An elastic implantation traction rod is slidably mounted within the implantation rod, with one end fixed within the implantation rod and equipped with an insertion button, and the other end extending to the outside of the implantation rod and fitted with a tear punctum plug. This invention has a simple structure, is easy to operate, the tear punctum plug is concealed and not easily falls out, the dilator is located on the side of use for better implantation effect, and it is removable for cleaning and sterilization. However, it still has the following drawbacks: (1) The existing implant is placed in a blister pack and the opening is then sealed by heat sealing with dialysis paper. During packaging, sterilization, transportation, unpacking and clinical use, the punctal plug is at risk of falling off. Moreover, the punctal plug is very small and is only fixed to the tip of the implant. It will not fit tightly because there is an implantation operation. If it fits tightly, it cannot be implanted.

[0004] (2) Existing implants do not have a fully locked structure after connection, which affects the stability of the connection.

[0005] Therefore, we made improvements and proposed an integrated punctal plug implant expander. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] like Figure 1-4 As shown, this embodiment proposes an integrated punctal plug implant dilator, including an implanter 1, wherein docking components are provided on the upper end and both sides of the implanter 1, and an implantation component is provided inside the implanter 1. The docking assembly includes a threaded ring 201 provided on the upper edge of the implant 1, and an expander 202 is detachably fitted on the upper exterior of the implant 1. The expander 202 has a cylindrical groove 203 inside that cooperates with the implant 1. The implantation component includes an implantation button 301 located inside the front end of the implanter 1, and a tear punctum plug 302 located inside the upper end of the implanter 1.

[0023] like Figure 3 As shown, the inner edge of the lower end of the cylindrical groove 203 is provided with an inner ring 204 that cooperates with the threaded ring 201. The twisting expander 202 is engaged with the inner ring 204 on the surface of the threaded ring 201, thereby allowing the expander 202 to be rotated and installed on the upper outside of the implanter 1.

[0024] For example Figure 1 As shown, top plates 205 are fixedly installed on both sides of the expander 202. Slots 206 are provided inside the top plates 205. Insert plates 209 are inserted into the aligned slots 206 to stably and firmly connect and fix the expander 202 to the implanter 1.

[0025] like Figure 1As shown, the outer walls of both ends of the implant 1 are fixedly equipped with base plates 207 corresponding to the positions of the top plate 205. When it is necessary to connect the implant 1 with the expander 202, the insert plate 209 is pulled down to move down in the slot 208, which drives the side plate 211 to move down in the side groove 210, squeezing the spring rod 212 to shrink it. At the same time, the upper end of the insert plate 209 shrinks into the slot 208, and the expander 202 is placed downward on the upper side of the implant 1. The expander 202 is twisted and engaged with the inner ring 204 on the surface of the threaded ring 201, so that the expander 202 is rotated and installed on the upper outside of the implant 1. After the complete twisting, the tension on the insert plate 209 is released, and the spring rod 212 pushes the side plate 211 upward, causing the insert plate 209 to be inserted into the aligned slot 206.

[0026] like Figure 4 As shown, the base plate 207 has a slot 208 inside, and an insert plate 209 that cooperates with the slot 206 is slidably disposed inside the slot 208. The expander 202 is rotatably mounted on the outside of the upper end of the implant 1. After being fully twisted, the tension on the insert plate 209 is released, and the spring rod 212 pushes the side plate 211 upward, causing the insert plate 209 to be inserted into the aligned slot 206. This allows the expander 202 to be stably and firmly connected and fixed to the implant 1, effectively protecting the tear duct plug 302.

[0027] like Figure 4 As shown, the slot 208 has side grooves 210 on both sides, and the insert plate 209 has side plates 211 on both sides that cooperate with the side grooves 210. A spring rod 212 is installed on the lower outer wall of the side plate 211. Pulling the insert plate 209 downwards causes it to move down in the slot 208, which in turn causes the side plate 211 to move down in the side groove 210, squeezing the spring rod 212 to shrink it. At the same time, the upper end of the insert plate 209 shrinks into the slot 208, which facilitates subsequent insertion and fixing.

[0028] like Figure 1 As shown, the implantation component also includes a transparent observation port 303 located on the front side wall of the expander 202. The tear punctum plug 302 is efficiently and conveniently implanted into the tear punctum area via the implantation button 301. Meanwhile, the expander 202 is transparent, so the tear punctum plug 302 can be observed from the outside.

[0029] Specifically, when using the implant 1: when it is necessary to connect the implant 1 to the expander 202, pull down the insert plate 209 so that it moves down in the slot 208, causing the side plate 211 to move down in the side slot 210, squeezing the spring rod 212 to contract it, and at the same time, causing the upper end of the insert plate 209 to contract into the slot 208, and then put the expander 202 down on the upper side of the implant 1. Twist the expander 202 so that it engages with the inner ring 204 on the surface of the threaded ring 201, thereby making the expander 202... 2. The device is rotated and installed on the upper exterior of the implant 1. After fully twisting, the tension on the insert plate 209 is released. The spring rod 212 pushes the side plate 211 upward, causing the insert plate 209 to be inserted into the aligned slot 206. This allows the expander 202 to be stably and securely connected to the implant 1. The punctum plug 302 can be efficiently and conveniently implanted into the punctum area through the implantation button 301. At the same time, the expander 202 is transparent, and the punctum plug 302 can be observed from the outside, improving the ease of use of the implant 1.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
