Embodiment Construction

[0016] figure 1 Schematic dental surgical instrument "Side Filler" which is indispensable during dental root canal treatment.

[0017] figure 2 It shows that the overall outer surface of the needle-shaped body 1 as the prior art "side filler" is smooth, and the slender "gutella tip" is transported (pressed) into the slender tooth root canal At the time, it mainly relies on the friction force when the needle-shaped body 1 contacts the vertical side of the "gut-jaw tip". Since the friction force between the needle-like body 1 and the "gut-jaw tip" is very small, the whole It is very troublesome in the above-mentioned pressure delivery process. It’s just that when the existing “side filler” is pulled out again, since the cylindrical surface of the existing needle-like body 1 is smooth, the friction between it and the “gut-filler tip” is very small, so the “ When the "side filler" is pulled out from the root canal of the tooth, it is quite smooth and trouble-free.

Abstract

An improved dental surgical instrument, which is composed of two matching side fillers, each of which is composed of a smooth needle-like body (1) and a needle handle (2), and is characterized in that the matching One of the side fillers is: a "pressure-feeding needle" that makes one side of the above-mentioned needle-like body (1) in the length direction into a downward-sloping sawtooth (3)-shaped side; The other is: by making one side of above-mentioned acicular body (1) in the length direction the " pulling needle " of upward inclined sawtooth (4) shape side. Since the original "side filler" is changed to a side surface of the above-mentioned smooth needle-shaped body (1) with serrations with different structural and shape requirements, it is quite convenient to use the downward-sloping serrations (3) to the root canal during the operation. Internal pressure sends " gutta-percha point " and utilizes upward inclination sawtooth (4) to pull out " gutta-percha point " and all creates conditions.

Description

Technical field: [0001] The invention relates to the structural technology of a dental surgical instrument "side filler" that must be used when filling the "gutella tip" in the process of dental root canal treatment. Background technique: [0002] The existing dental surgical instrument "side filler" (usually made of stainless metal) is composed of a cylindrical smooth needle and a needle handle (hand pinching force application part) at its rear part. Canal treatment, that is, after removing the nerve in the root canal, it is necessary to send a filling "gutella tip" with a diameter of less than 1 mm (made of soft, non-toxic plastic that will not deteriorate qualitatively) into the treated tooth with a diameter of less than 1mm. 1mm in the root canal, or when it is necessary to replace the "gut glue tip" that has been in place in the root canal, it is necessary to use the dental surgical instrument "side filler". The body presses the "gut glue tip" sideways and transports i...
