Mixing type tooth filling device

Abstract

The invention discloses a mixing type tooth filling device. The mixing type tooth filling device comprises an empty casing, wherein a slide bushing is fixed in the empty casing and divides interior ofthe empty casing into a first accommodating cavity and a second accommodating cavity which are closed relatively from left to right, a mixing casing is communicated with the lower part of the empty casing, one end of a shaft lever is located in the mixing casing, the other end penetrates the slide bushing and extends to the upper end of the empty casing, a push plug plate is fixed on the shaft lever, a first envelope is detachably fixed on the inner wall of the first accommodating cavity, a second envelope is detachably fixed on the inner wall of the second accommodating cavity, the first envelope is connected with the push plug plate through a first support rod, the second envelope is connected with the push plug plate through a second support rod, the inner wall, below the push plug plate, of the mixing casing is outwards recessed to form an annular groove, and the lower end of the mixing casing is communicated with an extrusion needle. The problem that a filling device capable of performing pre-mixing is absent at present is solved.

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 ...
