Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a root canal flushing needle head.
Background
Root canal refers to a canal in the middle of a tooth that connects the pulp chamber and the root tip. The blood vessels, nerves and lymphoid tissue of the tooth all enter or exit the pulp chamber from this point. In the treatment of dental diseases, it is necessary to remove germs and inflammation in root canals by root canal treatment.
Endodontic procedures require the use of a root canal irrigation needle (a tool for endodontic procedures), which is typically made of stainless steel or nitinol. It has many different shapes and sizes and can be adapted to the root canal morphology of different teeth. In the root canal treatment process, a doctor can use a root canal cleaning needle to clean bacteria and necrotic tissues in the root canal, and simultaneously, the root canal file is utilized to expand a root canal channel, so that the root canal medicine and the root canal filling material are convenient to fill.
Root canal files are also a tool for root canal treatment, typically made of nitinol, for removing necrotic tissue and bacteria from the canal and creating space for filling material. Root canal files are generally round or conical in shape, with different sizes and lengths to accommodate different root canal shapes and sizes.
The patent with publication number CN214414937U discloses a disposable root canal flushing needle, which overcomes the defect of the traditional root canal flushing needle made of metal materials, but fails to explore the length (depth) of the root canal, so that a doctor cannot conveniently judge the placement depth of the root canal file in the subsequent treatment process, and the medical risk is high.

The present utility model will be described in detail below with reference to the accompanying drawings and examples.
The present utility model provides a root canal flushing needle, as shown in fig. 1-3, comprising: a cleaning tube 1 for being inserted into the root canal, and a connector 2 which is provided with an internal channel 21 and is connected with a syringe; the connector 2 is fixedly connected with the cleaning pipe 1; the internal passage 21 communicates with the initial end of the purge tube 1; at least one cleaning hole 11 is formed in the side wall of the tail end of the cleaning tube 1, and a plurality of scale marks 12 used for displaying the depth of the cleaning tube 1 inserted into the root canal are arranged on the outer wall of the initial end.
In the embodiment, the cleaning tube 1 and the connector 2 are both made of medical grade PP materials; the cleaning pipe 1 is easy to bend because of the length-diameter ratio, and further stretches into the inner wall of the root canal, the tip of the root canal, the traffic branches among the pipes and other parts; the right upper end of the connector 2 is used for sealing and sleeving a liquid outlet of the injector, and the outer surface (the region D in fig. 2) of the connector is provided with sand grains (not shown in the drawing) which are convenient to install on the injector or detach from the injector; the left lower end of the connector 2 is sealed and fixed at the upper end of the cleaning tube 1; the utility model is divided into two parts of the cleaning pipe 1 and the connector 2, so as to facilitate the injection molding and the composition of the parts, and the practical production can also adopt a secondary injection molding integrated molding process, namely, the cleaning pipe 1 is firstly injected, then the cleaning pipe 1 is put into a mould for secondary injection molding, and the structure that the connector 2 is welded and fixed on the cleaning pipe 1 is formed. The connector 2 can be cylindrical or a bent cylindrical structure, in this embodiment, in order to facilitate a doctor to obtain a larger operation space to extend the cleaning tube 1 into the root canal, the connector 2 is arranged in a bent cylindrical structure, and the bending angle is 115 ° -120 °, as shown in fig. 2C; a cleaning hole 11 is formed at the lower end (tail end) of the cleaning tube 1; the upper end (initial end) of the cleaning tube 1 is provided with 3-5 scale marks 12, the scale marks 12 are annular and are wound on the outer wall of the cleaning tube 1, so that a doctor can conveniently probe the depth of the cleaning tube 1 extending into the root canal from a plurality of angles, and the depth of the root canal is judged.
According to the depth of the root canal, a doctor can judge the specific length of the root canal file which should extend into the root canal in the follow-up process, so that the root canal file and the root canal filling material are prevented from extending too deeply, the pain of a patient is caused, and the root canal needs to be opened again for flushing and filling; and the root canal file is prevented from being too shallow and too little medicine is put into the file, so that the medicine in the root canal is not filled, and the root canal treatment fails.
Further, a closing cap 13 is provided at the end of the cleaning tube 1, and the cleaning hole 11 is located at the side wall of the cleaning tube 1.
As shown in fig. 3, the closing cap 13 is hemispherical, reducing the risk of the cleaning tube 1 damaging the nerves of the teeth; the cleaning holes 11 are placed at the side wall positions of the cleaning tube 1 so that caries can be cleaned more directly in a relatively narrow root canal space.
Further, the cleaning holes 11 are formed on one side and the other side of the cleaning tube 1.
As shown in fig. 3, one cleaning hole 11 is located on the left side of the cleaning tube 1, and the other cleaning hole 11 is located on the right side of the cleaning tube 1; the sealing cap 13 is matched with the cleaning holes 11 on two sides, so that infectious substances in the root canal can be cleaned, and the phenomenon that flushing liquid exceeds the root tip holes to bring infection to the root tip periphery during flushing can be avoided, and pain reaction after operation is avoided.
Further, the cleaning hole 11 is circular; when the washing pipe 1 is vertically placed, the two washing holes 11 are located at different levels.
As shown in FIG. 3, the cleaning hole 11 is circular, the diameter is 0.2-0.24mm, the distance between the center of the cleaning hole 11 on the left side and the sealing cap 13 is about 0.5mm, the distance between the center of the cleaning hole 11 on the right side and the sealing cap 13 is about 0.9mm, and the cleaning holes are not positioned at the same horizontal height, so that the connection strength between the sealing cap 13 and the cleaning tube 1 body is enhanced, and the sealing cap 13 is prevented from being broken and remained in the root canal in the cleaning process.
Further, the cleaning tube 1 has an effective cleaning length of 22mm and a lower end diameter of 0.3mm, and is tapered as a whole.
As shown in FIG. 3, the cleaning tube 1 has a lower end diameter of 0.3mm (i.e., the diameter of the closing cap 13), an effective cleaning length of about 22mm (the length at A in FIG. 2), an overall length of about 28mm (the length at B in FIG. 2), and a taper ratio of about 3:220.
Further, the number of the graduation marks 12 is five, namely an 18mm graduation mark 121, a 19mm graduation mark 122, a 20mm graduation mark 123, a 21mm graduation mark 124 and a 22mm graduation mark 125.
As shown in fig. 1, the graduation marks 12 are provided at the upper end of the effective cleaning portion of the cleaning tube 1, and are 18mm graduation marks 121, 19mm graduation marks 122, 20mm graduation marks 123, 21mm graduation marks 124, and 22mm graduation marks 125, respectively, from below.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
