Abstract
The utility model relates to the technical field of medical device, especially a novel cervical dilating device. Two branches of a Y-shape body made of memory alloy are connected fixedly with dilating arms, around which the heat insulation layers are covered. The back end of the Y-shape body is connected with a heating rod, through which the memory alloy is heated. The branches in the front end of the memory alloy drive the dilating arms to dilate cervical. The device has a simple structure, is convenient to use, and would not bring pain to patients.
Description
Technical field
This utility model relates to medical instruments field, especially is a kind of novel cervical dilatation device.
Background technology
In gynecologial examination, often need to use cervical dilator that patient's cervix uteri is expanded.The cervical dilatation device operation of using at present is cumbersome, and easily brings misery to the patient, makes troubles for medical work simultaneously.
The utility model content
For overcoming above-mentioned technical deficiency, this utility model provide a kind of simple to operate, can not bring painful novel cervical dilatation device to the patient.
For realizing above-mentioned technical purpose, this utility model is realized by the following technical solutions: a kind of novel cervical dilatation device, comprise a Y body of making by memorial alloy, the bifurcated of Y body front end is closed form at normal temperatures, the Y-shaped shape in heating back, and two divergent ends of Y body are fixedly connected with expansion arm, expansion arm is with thermal insulation layer outward, the rear end of Y body connects heating rod, and the heating rod tail end is provided with lead, can connect external power source by lead.
This utility model is compared with conventional art, has following beneficial effect: because at normal temperatures, the front end of Y body is closure state, two expansion arm are fitted in one, put into patient's cervix uteri after, heat to memorial alloy by heating rod, the bifurcated of memorial alloy front end drives expansion arm and expands, play the purpose of cervical dilatation, it is simple in structure, and is easy to operate.
