Detailed Description

The attached drawings are specific embodiments of the invention. As shown in fig. 1 to 3, the propeller for obstetrics and gynecology department comprises an outer cylinder 1 and a propelling rod 2, wherein the outer end (taking a handheld part as the outer end and the other end as the inner end) of the outer cylinder 1 is the same as the outer cylinder of a common syringe, the outer end is bent outwards, but the other end of the outer cylinder 1, namely the inner end is not blocked, the inner end of the outer cylinder 1 is in threaded connection with an elastic cone 3, the elastic cone 3 comprises a threaded section 31 and a plurality of elastic strips 32, the elastic strips 32 form a cone part, the elastic strips 32 and the threaded section 31 are integrally manufactured, and the inner diameter of the threaded section 31 is the same as the inner.

The inner key of the outer cylinder 1 is connected with an inner dosing cylinder 4, the inner dosing cylinder 4 can smoothly enter a thread section from the outer cylinder 1, the outer end of the inner dosing cylinder 4 extends outwards to form a flange 5, the inner wall of the outer cylinder 1 is provided with two limiting arc-shaped plates 6, the plane where the two limiting arc-shaped plates 6 are located is vertical to the axial lead of the outer cylinder 1, the flange 5 of the inner dosing cylinder 4 is located between the two limiting arc-shaped plates 6, and the distance between the two limiting arc-shaped plates 6 determines the stroke of the inner dosing cylinder 4; the inner end of the drug delivery inner cylinder 4 is spherical, and a plurality of horn-shaped drug outlets 7 are arranged on the drug delivery inner cylinder.

The flange 5 section of the administration inner cylinder 4 is connected with an auxiliary inner cylinder 41 through outward threads, one end, far away from the flange 5, of the inner wall of the auxiliary inner cylinder 41 is provided with two groups of guide plates, the two groups of guide plates are symmetrically arranged with the axial lead of the auxiliary inner cylinder 41, each group of guide plates comprises two transverse guide plates 8, the two transverse guide plates 8 are arranged in parallel and are perpendicular to the axial lead of the auxiliary inner cylinder 41, the two transverse guide plates 8 are arranged in a staggered mode, the transverse guide plate 8 on the inner side extends out of the outer longitudinal guide plate 9 towards the direction of the flange 5, the transverse guide plate 8 on the outer side extends out of the inner longitudinal guide plate 10 towards the direction of the medicine outlet 7, and gaps 11 are reserved between the transverse guide plate 8 on the inner side and the inner longitudinal guide plate 10 and between the transverse guide plate 8 on the outer side and the outer.

The push rod 2 is arranged inside the medicine feeding inner barrel 4, two guide rods 12 are symmetrically arranged on the push rod 2, the two guide rods 12 can penetrate through the two gaps 11 and the two transverse guide plates 8, and when the guide rods 12 are arranged between the two transverse guide plates 8, the push rod 2 can drive the medicine feeding inner barrel 4 to pull.
