AI Technical Summary

Technical Problem

Existing gynecological microneedle devices have an integrated design of handle and roller microneedle after use, making it difficult to replace them separately. This results in waste and unhygienic conditions.

Method used

A gynecological microneedle was designed, including a handle and a disposable roller. The roller can be quickly replaced through a mounting component and a support component. Multiple sets of microneedles are installed on the roller, and the support component has a protective cover to prevent accidental injury to the operator.

Benefits of technology

It enables convenient replacement of the rollers, improves the hygiene of the device, avoids bacterial transmission, reduces waste, and improves drug absorption efficiency through the rotation of multiple sets of microneedles.

Abstract

The utility model discloses a gynecological microneedle, which belongs to the technical field of medical instruments and comprises a holding rod and a disposable roller. The end of the holding rod is fixedly connected with one end of a connecting rod, and the other end of the connecting rod is fixedly provided with a fixing frame. The fixing frame comprises a mounting assembly and a supporting assembly, the mounting assembly is mounted at the end, away from the holding rod, of the connecting rod, and the supporting assembly is mounted on the mounting assembly and the roller. A roller is rotatably mounted on the supporting assembly, a plurality of needle groups which are uniformly distributed at equal intervals in a circumferential array are fixedly mounted on the roller, each needle group comprises a plurality of micro-needles, and the plurality of micro-needles are uniformly distributed at equal intervals in the axis direction of the roller. By means of the mode, an operator can rapidly install the disposable roller on the supporting assembly through the installation assembly, and replacement of the roller is achieved; by replacing the roller, the device is more sanitary and convenient, bacterial infection is avoided, meanwhile, the holding rod and the connecting rod can be repeatedly used, and waste is avoided; and the protective cover prevents operators from being accidentally injured.
