Embodiment Construction

[0014] The dental surgical instrument "side filler" shown in Fig. 1 is indispensable in the dental root canal treatment process.

[0015] Fig. 2 has schematically illustrated the overall outer surface of the needle-like body 1 as forming prior art " side filler ", all is smooth, and is transported (compressed) in the elongated tooth root canal with elongated " gutta-percha point " When sending), it mainly relies on the friction force when the needle-like body 1 contacts the vertical side of the "gut-mouth rubber tip". It is very troublesome in the whole 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.

[0016] Fig. 3 and Fig. 4 illustrate that the two needle-sha...

Abstract

An improved lateral filling device of dental operation instruments is based on the prior structure, which consists of two sections of a spicula (1) and a handle (2) of the spicula. The lateral filling device is characterized in that the lateral filling device respectively consists of a declined-sawtooth-(3)-shaped lateral pressing-feeding needle which is made by the spicula (1) at one lateral side along the lengthways direction and a ascending-sawtooth-(4)-shaped lateral pulling-discharging needle which is made by the spicula at one lateral side along the lengthways direction; because the former lateral filling device is changed as that one lateral side of the smooth spicula (1) is provided with the sawteeth of different structure and shape requirements, the improved lateral filling device creates conditions for the operation that the declined sawtooth (3) can be very conveniently used for pressing and feeding gutta-percha points into the tooth root canal, and the ascending sawtooth (4) is used for pulling and discharging the gutta-percha points outwards.

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...
