AI Technical Summary

Technical Problem

The existing intraocular lens boring device is difficult to control the force when pushing into the intraocular lens, resulting in uneven push speed and inconvenient operation.

Method used

A driving structure of a bobbin, including a bobbin, a rotating shaft, a connecting rod and a bobbin. By pushing the push cylinder to drive the rotation shaft, the threaded groove of the shaft drives the connecting rod to perform linear movement, thereby driving the push injection rod to perform linear movement and achieving uniform pushing in.

Benefits of technology

It reduces the stress sensitivity of the bolt, makes it easier for medical personnel to master the push force, realizes uniform propulsion of the intraocular lens, and can be operated with one hand, making the operation simple and convenient.

Abstract

The utility model relates to the field of medical instruments, and discloses a driving structure of an injector and an intraocular lens injector, and the driving structure comprises an injection cylinder and an injection rod; a rotating shaft is rotationally mounted close to the inner wall of the injection cylinder, the top of the rotating shaft is a spiral section, and a threaded groove is formed in a shaft body below the spiral section; a push cylinder capable of pushing the rotating shaft to rotate is inserted into the spiral section of the rotating shaft; a connecting rod piece is movably installed on a shaft body of the rotating shaft, the other end of the connecting rod piece is connected with the injection rod, and the rotating shaft drives the connecting rod piece to do linear motion through the threaded groove while rotating. The rotating shaft can be driven to rotate by pushing the push cylinder, and then the rotating shaft drives the connecting rod piece to do linear motion, so that the connecting rod piece drives the injection rod to do linear motion, the threaded groove of the rotating shaft drives the injection rod to do linear motion after the push cylinder is pushed in, the stress sensitivity of the injection rod can be reduced through the design, and the service life of the injection rod is prolonged. And the intraocular lens can be operated by one hand, so that the operation is simple and convenient.
