Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment protection, and in particular to a protective device for the tip of a punctum expander. Background Technology

[0002] A punctal dilator is a sophisticated ophthalmic surgical instrument with an extremely fine and precise tip. It is primarily used to treat punctal stenosis or obstruction by dilating the punctum, increasing the tear drainage channel, improving tear drainage, and relieving symptoms such as tearing and eye discomfort caused by tear buildup. It can also be used for punctal examination, helping doctors to better observe its shape and function, and can be used during punctal irrigation to remove blockages and restore normal tear drainage. Furthermore, in punctal cannulation and some punctal surgeries (such as punctal excision and suturing), the punctal dilator provides better visibility and space for cannulation, fixation, and surgical procedures. However, it is prone to collisions and compression during retrieval, which can lead to twisting and damage to the tip.

[0003] To address the aforementioned issues, existing technologies typically equip lacrimal punctum dilators with a protective sleeve. However, in actual use, this sleeve can easily be pulled back too far, causing medical staff's fingers to be pierced by the tip. This can easily lead to bacterial infection and occupational exposure. Therefore, we propose a protective device for the tip of a lacrimal punctum dilator. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a protective device for the tip of a tear punctum expander. By setting up a protective sleeve and a support ring, the device can reduce collision and torsion damage during the retrieval process and effectively reduce occupational exposure problems.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A protective device for the tip of a tear punctum expander includes a protective mechanism, a marking mechanism embedded on the surface of the protective mechanism, a support mechanism fixedly installed at the end of the protective mechanism, and an expansion mechanism nested at the front end of the protective mechanism. The protective mechanism includes a protective sleeve with a nesting opening at the front end and an insert opening on the outer surface of the nesting opening. By using the protective sleeve, the device can effectively nest and protect the pointed rod, reducing damage caused by friction and collision during the recycling process and improving the safety of the device.

[0006] Furthermore, the marking mechanism includes a base plate, a marking plate is fixedly installed at the front end of the base plate, and an insert block is fixedly installed at the rear end of the base plate. By setting the marking plate, the device can be marked with different models, which makes it easier for medical staff to select the right device according to different models, thus improving the convenience and accuracy of the device.

[0007] Furthermore, the support mechanism includes a support ring with a slit at the front end. By providing the support ring, medical personnel can stand the entire device upright on the table for single-handed re-sleeving when re-sleeving, avoiding occupational exposure issues caused by re-sleeving with both hands and improving the safety of the device.

[0008] Furthermore, the extension mechanism includes a handle, a base is fixedly installed at the center of the rear end of the handle, and a pointed rod is fixedly installed at the center of the rear end of the base. By setting the base, the protective sleeve can be locked onto the base when the device is nested, making the nesting more secure and improving the safety and stability of the device.

[0009] Furthermore, the protective case is made of soft silicone and is cylindrical in shape.

[0010] Furthermore, the label plate is rectangular in shape and is adapted to the base plate.

[0011] Furthermore, the support ring is circular in shape and is adapted to the protective sleeve.

[0012] Furthermore, the base is cylindrical in shape and is adapted to the protective sleeve.

[0013] In summary, this utility model has the following beneficial effects: 1. By setting a protective sleeve, the device can effectively protect the pointed rod by nesting, reducing damage caused by friction and collision during the retrieval process and improving the safety of the device. By setting a support ring, medical staff can stand the entire device upright on the table for one-handed retrieval when retracting, avoiding occupational exposure problems caused by retracting with both hands and improving the safety of the device. 2. By setting a label plate, the device can be marked with different models, making it easier for medical staff to select the right model. This improves the convenience and accuracy of the device. By setting a base, the protective cover can be secured to the base when the device is nested, making the nesting more secure and improving the safety and stability of the device.

The protective mechanism 1 includes a protective sleeve 101. The front end of the protective sleeve 101 is provided with a nesting opening 102, and the outer surface of the nesting opening 102 is provided with an insertion opening 103. The protective sleeve 101 is made of soft silicone and is cylindrical in shape. By setting the protective sleeve 101, the device can effectively nest and protect the pointed rod 403, reduce the damage caused by friction and collision during the recycling process, and improve the safety of the device.

[0019] Reference Figure 1-3 As shown, the labeling mechanism 2 includes a base plate 201, a labeling plate 202 is fixedly installed at the front end of the base plate 201, and an insert block 203 is fixedly installed at the rear end of the base plate 201.

By setting the labeling plate 202, the device can be marked with different models, which makes it easier for medical staff to select the right model and improves the convenience and accuracy of the device.

[0020] Reference Figure 1-4As shown, the support mechanism 3 includes a support ring 301 with a slit 302 at the front end. The support ring 301 is circular in shape and is adapted to the protective sleeve 101. By setting the support ring 301, medical staff can stand the entire device upright on the table and perform single-handed re-sleeving when re-sleeving, avoiding occupational exposure problems caused by re-sleeving with both hands and improving the safety of the device.

[0021] Reference Figure 1-5 As shown, the extension mechanism 4 includes a handle 401, a base 402 is fixedly installed at the center of the rear end of the handle 401, and a pointed rod 403 is fixedly installed at the center of the rear end of the base 402. The base 402 is cylindrical in shape and is adapted to the protective sleeve 101. By setting the base 402, the protective sleeve 101 can be locked onto the base 402 when the device is nested, making the nesting more secure and improving the safety and stability of the device.

[0022] Specific implementation process: Medical staff observe the model markings on the rectangular label plate 202 in the labeling mechanism 2, and select the device that matches the required punctal expander model from multiple protective devices, based on the patient's needs or surgical type. The labeling mechanism 2 is fixed by fitting the insert block 203 into the insert opening 103 of the protective mechanism 1, ensuring that the model markings are clear and not easily detached, thus guaranteeing the accuracy of selection. After use, the working tip of the punctal expander, the pointed rod 403, is aligned with the nesting opening 102 at the front end of the protective mechanism 1 and slowly pushed into the protective sleeve 101. The protective sleeve 101 is a cylindrical structure made of soft silicone, which is elastic and can tightly wrap the pointed rod 403 to prevent damage caused by friction and collision during recycling and storage, while also preventing the pointed rod 403 from accidentally pricking medical staff. When the pointed rod 403 is fully pushed in, the cylindrical base 402 of the expansion mechanism 4 will... The protective sleeve 101 engages at the end, and the compatibility between the base 402 and the protective sleeve 101 ensures a secure and stable fit. If the protective device needs to be removed from the pointed rod 403 and re-attached, medical personnel can use the support ring 301 of the support mechanism 3 to stand the support ring 301 upright on the operating table. Utilizing the stability of its circular structure, the re-attachment can be performed with one hand, avoiding contact with the area near the pointed rod 403 and reducing occupational exposure risks. The slit 302 at the front end of the support ring 301 is designed to fit the shape of the end of the protective sleeve 101, ensuring a secure connection between the support ring 301 and the protective sleeve 101 and not affecting the smoothness of the re-attachment operation. After the operation is completed, the protective device with the pointed rod 403 can be directly recycled, and the protective sleeve 101 continues to protect the pointed rod 403 from external damage. If it is a reusable device, it can be quickly classified and disinfected through the markings on the label plate 202, facilitating accurate selection by model next time. A protective sleeve 101 made of soft silicone material is used to wrap the tip rod 403, which reduces the damage to the tip rod 403 caused by external friction and collision through physical isolation, and avoids the safety hazards caused by the tip rod 403 being exposed. The base 402 and the protective sleeve 101 are matched and engaged, and the insert block 203 and the insert port 103 are matched to ensure that the connection of each mechanism is firm and prevent it from falling off. The label plate 202 enables visual differentiation of the model, and the support ring 301 provides a fulcrum for one-handed operation. Both improve the selection accuracy and operation safety, respectively. Finally, the structural adaptability of each mechanism enables them to work together to meet the clinical needs of protecting the tip of the lacrimal punctum expander.
