Mixed type tooth filling device

Abstract

The invention discloses a mixed type tooth filling device which comprises an empty sleeve; a sliding sleeve is fixed in the empty sleeve and divides the interior of the empty sleeve from left to rightinto a first accommodating cavity and a second accommodating cavity which are relatively closed; a mixing sleeve is communicated with the lower part of the empty sleeve; one end of a shaft rod is arranged in the mixing sleeve; the other end of the shaft rod penetrates through the sliding sleeve and extends to above the empty sleeve; the shaft rod is fixedly provided with a push-plug plate; the inner wall of the first accommodating cavity is detachably and fixedly provided with a first sealing skin; the inner wall of the second accommodating cavity is detachably and fixedly provided with a second sealing skin; the first sealing skin is connected with the push-plug plate through a first supporting rod; the second sealing skin is connected with the push-plug plate through a second supportingrod; the inner wall of the mixing sleeve, below the push-plug plate, is sunken outward to form an annular groove; and an extrusion needle is also communicated with the lower end of the mixing sleeve.The mixed type tooth filling device solves the problem that a filling device capable of performing premixing does not exist at present.

Description

technical field [0001] The invention relates to a medical device, in particular to a hybrid dental filling device. Background technique [0002] Clinically, doctors often choose different materials to fill the cavity according to the location of the affected tooth, the location of the cavity, the magnitude of the occlusal force, as well as the patient's health and aesthetic requirements. At present, many tooth filling materials are obtained by mixing non-aqueous phase materials and aqueous phase solutions. Before filling, the two materials are mixed to form a paste, and then injected into the cavity. At present, there is no one that can be pre-mixed. Filler, the traditional method is to mix the two materials externally and then inject them into the filler, which is not only cumbersome, but also prone to secondary pollution during the mixing process, introducing impurities or bacteria. Contents of the invention [0003] The purpose of the present invention is to provide a ...
