Accompanying drawing is the structural representation of cervical canal holder;
4, description of drawings
Explain below with reference to Figure of description cervical canal holder of the present utility model being done.
Cervical canal holder of the present utility model, its structure is to be made of last fixedly card 1 and down fixing card 4, upper and lower fixedly card 1,4 is semicircle, the left end of upper and lower fixedly card 1,4 is provided with the dentation interface 5 that coincide mutually, 3, two fixing heads 3 of fixing head that the right-hand member of upper and lower fixedly card 1,4 is provided with band fixing hole 2 are fixed together by set bolt 6 and make upper and lower fixedly card 1,4 composition ring-types connected with each other.5, embodiment:
Its processing and fabricating of cervical canal holder of the present utility model is very simple and convenient, processing and fabricating gets final product shown in the by specification accompanying drawing, fixedly card can use corrosion resistant plate to be processed into up and down, also can use the medical plastic injection moulding to make, use also very simple and convenient, the doctor can be fixed near the fornix vaginae portion cervix uteri with two semicircle cervical canal holders by operation, and the screw that is tightened gets final product.
Cervical canal holder of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, little, easy to use, the operation process of volume need not anesthesia, stimulate little to cervix uteri, no pain, simple to operate, safe and reliable, effect obviously, fixation is difficult for characteristics such as slippage, can replace traditional cervical cerclage fully, and the clinical application prospect is arranged very much.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
