Description

Disposable cervix dilatation stick

Technical Field

The utility model belongs to the technical field of medical consumables, in particular to a disposable cervix dilatation rod.

Background

When expanding the cervix before the examination of the uterine cavity of clinical gynaecology and obstetrics, the existing cervical dilating stick has the following defects that the length of a stick body entering a human body cannot be adaptively adjusted, and then the discomfort condition of the body of a patient can be caused.

Disclosure of Invention

The utility model aims at overcoming not enough among the prior art, providing a disposable cervix expansion stick, expand through the inflation that absorbs water, simultaneously through set up interior bushing pipe in the expansion stick is inside, make the limiting plate can pass through the threaded hole in the bushing pipe of bolted connection downthehole regulation and the distance between the barred body, and then can make the barred body get into the length in the human body.

In order to realize the purpose, the utility model discloses a technical scheme be:

the utility model provides a disposable cervical dilatation stick, includes barred body, spheroid, spacing subassembly, interior bushing pipe, screw hole, barred body one side is equipped with the spheroid, the inside bushing pipe that is equipped with of barred body, the inside screw hole that is equipped with of bushing pipe, interior bushing pipe one side is equipped with spacing subassembly, when using, leads out perineum portion through the spheroid, and the spheroid is comparatively mellow and full to improve as far as and use experience, places the barred body in internal back, accomplishes the fixed to the barred body simultaneously through spacing subassembly control barred body at internal length.

The limiting assembly comprises a bolt connecting shaft, a limiting plate and a rotating handle, the limiting plate is arranged on one side of the bolt connecting shaft, the rotating handle is arranged on one side of the limiting plate, one end of the bolt connecting shaft is fixedly connected onto the limiting plate, the other end of the bolt connecting shaft is connected into a threaded hole through threads, the rotating handle is fixedly connected to the other end of the limiting plate, when the control rod body enters the length of the inside of a human body, the limiting plate is driven to rotate through rotating the rotating handle, and then the bolt connecting shaft is moved in the lining pipe.

Preferably, the limiting plate is internally provided with a plurality of through holes so as to facilitate liquid drainage.

Compared with the prior art, the utility model beneficial effect shows:

through add interior bushing pipe in the expansion stick is inside, make the limiting plate can pass through the threaded hole of bolted connection axle in the inside lining pipe adjust and the distance between the barred body, and then can make the barred body get into the length in the human body, can carry out adaptability according to patient's actual conditions and adjust, reduce the discomfort of patient's health.
