Abstract
Description
Technical Field
[0001] This utility model relates to the field of ophthalmic treatment equipment, and in particular to an electrolytic ingrown eyelash needle. Background technology:
[0002] Ingrown eyelashes are the phenomenon where eyelashes turn towards the side of the eyeball, and are associated with trachoma, blepharitis, trauma, etc. Ingrown eyelashes rub against the conjunctiva and cornea, causing foreign body sensation, photophobia, blepharospasm, and even corneal opacity and ulceration. Compared to directly plucking the eyelashes, electrolysis can destroy the eyelash follicles, providing a thorough treatment and preventing the ingrown eyelashes from growing back.
[0003] The existing treatment method involves the following steps after local anesthesia: First, wrap the anode of the electrolyzer with wet saline gauze and apply it tightly to the skin on the temporal side; then, with one hand, turn the eyelid to expose the edge of the face, and with the other hand, hold the electrolyzer needle connected to the cathode and insert it 2mm into the eyelash root, parallel to the eyelash growth, until it reaches the hair follicle; turn on the current for about 3 to 10 seconds, and when white foam is seen to overflow, remove the needle and use eyelash tweezers to remove the ingrown eyelashes.
[0004] After use, the electrolytic needle, which serves as the cathode, needs to be removed and replaced with a new one. The existing electrolytic needle uses a plug-in connection with the rear conductive structure. In order to achieve the conductivity effect, the electrolytic needle is fixed tightly and the needle tip is thin and long, making the insertion and removal process difficult and easily causing injury to medical personnel and damage to equipment. Utility Model Content
[0005] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the objective of this invention is to provide a device that facilitates needle replacement while maintaining stable contact and conductivity.

[0007] Outer shell: hollow, with a movable push rod inside;
[0008] Push rod: One end is equipped with a gripper to hold the treatment needle. The outer shell around the gripper has a tapered inner wall. The gripper moves inside, and the treatment needle passes through the corresponding mounting hole formed in the outer shell. The other end of the push rod is equipped with an electrode post. The current of the electrode post passes through the electrode post and the gripper to the treatment needle.
[0009] A spring is installed between the push rod and the outer shell. The spring pushes the push rod outward, and the gripper is squeezed by the inner wall of the outer shell to clamp the treatment needle. Pressing causes the push rod to move inward into the outer shell, the gripper is squeezed less, and the treatment needle is released.

An external power source is connected, and the current is transmitted through the treatment needle to the hair follicle, destroying the hair follicle. After use, the push rod is pressed to release the treatment needle for replacement.
[0011] In addition, the electrolytic ingrown eyelash needle proposed in the above embodiments of this utility model may also have the following additional technical features:
[0012] Optionally, the outer casing forms an inward hemispherical recess, with mounting holes formed at the bottom of the hemispherical shape.
[0013] Optionally, the outer side of the gripper also has a taper to match the taper of the inner wall of the housing.
[0014] Optionally, the push rod includes a conductive rod and a handle. One end of the conductive rod has several grooves along its length to divide one end of the conductive rod into the gripper. The other end of the conductive rod has a connecting hole along its length for inserting the electrode post.

[0029] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0031] Figures 1 to 5 An electrolytic ingrown eyelash needle according to an embodiment of the present invention includes:
[0032] Outer shell 1: hollow, with a movable push rod 2 inside;
[0033] Push rod 2: One end is provided with a gripper 211 for holding the treatment needle 5. The outer shell 1 around the gripper 211 has a tapered inner wall. The gripper 211 moves inside, and the treatment needle 5 passes through the mounting hole 12 formed in the outer shell 1. The other end of the push rod 2 is provided with an electrode post 3. The electrode post 3 transmits current to the treatment needle 5 through the gripper 211.
[0034] A spring 4 is provided between the push rod 2 and the outer shell 1. The spring 4 pushes the push rod 2 outward, and the gripper 211 is squeezed by the inner wall of the outer shell 1 to tighten the treatment needle 5. Pressing causes the push rod 2 to move inward into the outer shell 1, the gripper 211 is squeezed less, and the treatment needle 5 is released.
[0035] When in use, the length of the outer shell 1 and the push rod 2 should not exceed 4 cm. The thumb, index finger and middle finger can be used to pinch the outer shell 1 to control the depth of needle insertion. After treatment, a brand new needle needs to be replaced to prevent cross-infection. In this invention, the needle can be easily removed by pushing the push rod 2 to loosen the internal grip on the treatment needle 5. It is also convenient to install a new needle. Simply insert the needle with the gripper 211 open, and the push rod 2 will be reset by the action of the spring 4 to tighten the needle. This process can even be completed without touching the needle with your hands, minimizing the risk of needle puncture or contamination during needle loading and unloading.
[0036] The structure of this invention is similar to that of a mechanical pencil, with the treatment needle 5 acting as the lead core.
[0037] In some embodiments, the housing 1 forms an inward hemispherical recess, and the mounting hole 12 is formed at the bottom of the hemispherical shape. This structure is designed to facilitate the insertion of the pin and can serve as a guide.
[0038] Optionally, the outer side of the gripper 211 also has a taper, which matches the taper of the inner wall of the housing 1. In order to facilitate processing and reduce costs, the outer side of the gripper 211 is generally designed with a straight line. However, by adopting an external taper structure, the external mating area can be increased through the taper fit, which can reduce the wear on the moving structure and thus increase its service life.
[0039] In some embodiments, the push rod 2 includes a conductive rod 21 and a handle 22. One end of the conductive rod 21 has several grooves along its length, dividing one end of the conductive rod 21 into grippers 211. The other end of the conductive rod 21 has a connection hole 212 for inserting the electrode post 3 along its length. The heating hole 212 has an internal thread, and the conductive rod 21 has a corresponding external thread. The two are fixed together by the threaded engagement, which fixes the electrode post 3 and the conductive rod 21 together. In this scheme, except for the conductive rod 21, the electrode post 3 and the spring 4, everything else can be made of plastic material, which reduces costs, provides good insulation, and facilitates sterilization. Furthermore, when using a plastic shell 1, a metal (such as brass or phosphor bronze, and the corresponding conductive rod 21 can be made of brass or copper) bushing is provided in the area of the gripper 211. The bushing can reduce the wear of the shell 1 when the gripper 211 moves, and improve the service life.
[0040] Optionally, a limiting post 23 is formed by a protrusion on the surface of the push rod 2, and a corresponding limiting groove 13 is formed on the outer shell 1. The limiting groove 13 is T-shaped. The purpose of this design is to provide a better locking effect. Without this structure, by pulling the push rod 2 outward and the large pushing force of the spring 4 itself, the gripper 211 will not open during use, and the treatment needle 5 will not fall out accidentally. However, with the T-shaped groove, when changing the needle, the limiting post 23 slides vertically in the T-shape. After the needle is replaced, the push rod 2 is rotated axially, so that the limiting post 23 is engaged in the lateral direction of the T-shape, preventing the push rod 2 and the outer shell 1 from moving relative to each other, thus achieving a better locking effect.
[0041] Optionally, in order to better control the insertion depth of the treatment needle, a scale value is also set on the treatment needle. The scale value can be a laser-etched frosted texture or a color mark for easy observation. The scale division can be in millimeter intervals or specific division values set based on experience.
