Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to microneedles for gynecology. Background Technology
[0002] Microneedles are often used when delivering medication subcutaneously to the female lower genital tract to improve the speed and effectiveness of drug absorption. However, microneedles are small and difficult to control. Therefore, in practice, microneedles are often installed in a rolling unit, which allows for controlled operation of the microneedles.
[0003] For example, Chinese patent CN219783523U discloses a roller microneedle. The sleeve of the device is equipped with multiple microneedles and multiple liquid outlet holes. During operation, the solution is replenished to the skin from the microneedles, which is more uniform, efficient, and more flexible and convenient to use.
[0004] However, the parts of the instrument that come into contact with the human body should be replaced after use. The handle and roller microneedle of this device are designed as an integrated unit, making it difficult to replace the roller microneedle separately. Replacing the handle and roller microneedle together would be wasteful.
[0005] Based on this, the present invention designs a gynecological microneedle to solve the above problems. Utility Model Content

[0032] The present invention will be further described below with reference to the embodiments.
[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0034] Example 1
[0035] Please refer to the instruction manual appendix. Figure 1-3 Gynecological microneedles, including handle 100 and disposable roller 500;
[0036] The end of the grip 100 is fixedly connected to one end of the connecting rod 200, and the other end of the connecting rod 200 is fixedly mounted with a fixing bracket 300.
[0037] The fixing frame 300 includes a mounting assembly 310 and a support assembly 320. The mounting assembly 310 is mounted on the end of the connecting rod 200 away from the handle 100. The support assembly 320 is mounted on the mounting assembly 310 and the roller 500. The roller 500 is rotatably mounted on the support assembly 320. Multiple sets of needle groups are fixedly mounted on the roller 500 in a circumferential array with equal spacing. Each set of needle groups includes multiple microneedles 510, which are evenly distributed along the axial direction of the roller 500.
[0038] A protective cover 600 is also fixedly installed on the support component 320.
[0039] A groove 110 for easy gripping is provided on one end of the grip 100 near the connecting rod 200;
[0040] The grip bar 100 is provided with anti-slip grooves 120 for anti-slip purposes.
[0041] In this embodiment, when the gynecological microneedle is working normally, the operator can quickly install the disposable roller 500 onto the support component 320 using the installation component 310, thus replacing the roller 500. Replacing the roller 500 makes the device more hygienic and convenient, avoiding bacterial transmission. At the same time, the handle 100 and connecting rod 200 can be reused, avoiding waste. Then, by holding the handle 100, the microneedles 510 on the roller 500 come into contact with the human body. The handle 100 pushes the roller 500 to rotate through the connecting rod 200, the installation component 310, and the support component 320. The rotation of the roller 500 causes multiple sets of microneedles 510 on the roller 500 to come into contact with the human body, thereby inserting the microneedles 510 subcutaneously and making the drug solution more fully absorbed. During the operation, the protective cover 600 prevents the operator from being accidentally injured.
[0042] Example 2
[0043] like Figure 1-6As shown, in a preferred embodiment of the present invention, the mounting assembly 310 includes a limiting assembly and a connecting assembly. The limiting assembly is mounted on the end of the connecting rod 200 away from the grip rod 100, and the connecting assembly is mounted inside the limiting assembly.
[0044] The limiting assembly includes a sleeve 311, a groove 312, and a sliding rod 313. The middle part of the sleeve 311 is fixedly installed on the end of the connecting rod 200 away from the handle 100. The groove 312 is provided on one side of the sleeve 311, and the sliding rod 313 is slidably connected to the groove 312 for limiting.
[0045] The slide bar 313 is square;
[0046] The connecting assembly includes a receiving groove 314 and a spring 315. The receiving groove 314 is provided on the side of the slide rod 313 near the sleeve 311. The spring 315 is fixedly installed between the slide rod 313 and the sleeve 311. The spring 315 is located inside the receiving groove 314 and the slide groove 312.
[0047] The support assembly 320 includes a fixed rod 321, a movable rod 322, and a pin 323. One end of the fixed rod 321 is fixedly installed on the sleeve 311 at the end away from the slide rod 313, and one end of the movable rod 322 is fixedly installed on the slide rod 313 at the end away from the sleeve 311. The other ends of the fixed rod 321 and the movable rod 322 are respectively fixedly installed with a pin 323.
[0048] The support assembly 320 also includes slots 324. Slots 324 are provided at both ends of the roller 500, and slots 324 are inserted into the insert shaft 323.
[0049] In this embodiment, when the mounting assembly 310 and the support assembly 320 are working normally, pulling the moving rod 322 causes the sliding rod 313 to slide within the sliding groove 312. The limiting effect of the sliding groove 312 and the sliding rod 313 causes the moving rod 322 to move horizontally, increasing the distance between the fixed rod 321 and the moving rod 322. This increases the distance between the insertion shaft 323 on the fixed rod 321 and the moving rod 322, causing the spring 315 to stretch. This allows the slot 324 at one end of the roller 500 to be installed on the insertion shaft 323 on the fixed rod 321. At this time, the slot 324 at the other end of the roller 500 is aligned with the moving rod 322. Insert shaft 323 on rod 322; when insert shaft 323 is released, spring 315 resets and drives slide rod 313 to reset, thereby moving rod 322 to drive insert shaft 323 to reset, so that insert shaft 323 on moving rod 322 is inserted into insert shaft 323 at the other end of roller 500, thus realizing the installation of roller 500; after use, pull moving rod 322 to drive insert shaft 323 to move. Under the limiting action of slide groove 312 and slide rod 313, moving rod 322 horizontally, so that insert shaft 323 on moving rod 322 disengages from slot 324 on roller 500, thus facilitating the removal of roller 500.
[0050] The connecting rod 200 includes a fixed end 201, a rotating rod 202, a turbine groove 203, a worm gear 204, and an adjusting knob 205.

The other end of the rotating rod 202 is fixedly connected to 311. The rotating end of the rotating rod 202 has a turbine groove 203. The worm gear 204 is rotatably installed in the fixed end 201 through a rotating shaft. The rotating shaft of the worm gear 204 passes through the fixed end 201 and is fixedly connected to the adjusting knob 205. The worm gear 204 is engaged with the turbine groove 203.
[0051] The adjustment knob 205 drives the worm gear 204 to rotate via the rotating shaft. The worm gear 204 drives the rotating rod 202 to rotate via the worm groove 203, thereby adjusting the angle between the rotating rod 202 and the fixed end 201, which facilitates operation by the user.
[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 of the technical features.
