The embodiments of the present invention will be described below with reference to the drawings attached to the specification. It should be noted that the embodiments mentioned in the present description are not exhaustive and do not represent the only embodiments of the present invention. The following examples are given for the purpose of clearly illustrating the inventive contents of the present patent application and are not intended to limit the embodiments thereof. It will be apparent to those skilled in the art that various changes and modifications can be made in the embodiments described above, and it is intended to cover all modifications and variations of the present invention which fall within the true spirit and scope of the invention.
Throughout the specification, a part "including" a certain component means that other components may be included, but not excluded, unless there is a characteristic description contrary thereto.
Fig. 1 shows a flow chart of a method of manufacturing a reflux irrigation needle of the present invention. Fig. 2 is a schematic diagram of a manufacturing apparatus for a reflux irrigation needle according to a preferred embodiment of the present invention. FIG. 3 is a schematic view of the needle angle adjustment according to a preferred embodiment of the present invention. The process of the present invention is described in detail below with reference to FIGS. 1-3.
The method comprises the following steps of a-d.
Step a: and setting laser parameters of the laser equipment, wherein the laser parameters comprise repetition frequency, single pulse energy and focus spot size. Here, the laser apparatus includes a laser 2, an optical path mirror 3, and a processing head 4. The laser 2 is used for emitting laser beams, the light path reflector 3 is used for reflecting the laser beams to adjust the light path, and the processing head 4 is used for focusing the laser to the to-be-processed washing needle head. The irrigation needle to be processed (not shown in fig. 1) is fixed to a table 5. The laser 2 and the machining head 4 are controlled by a computer 1. The laser parameters are set according to the requirements of the process file. For example, the laser emitting laser wavelength is 100 nm-1200 nm, the pulse width is 100 ns-10 fs, the pulse frequency is 1-2000 KHz, the single pulse energy is in uj magnitude, and the single pulse energy can be specifically adjusted according to the metal material of the flushing needle head, the thickness of the tube wall, the punching inclination angle and the aperture size.
Step b: and setting the diameter parameter of the laser processing track. The parameters are set according to technical parameter requirements. Preferably, a proper processing head 4 is selected, so that a focusing light spot of laser passing through the processing head 4 is 10-30 um, and the specific numerical value is related to the size of the punched hole. The machining trajectory of the machining head 4 is precisely controlled by the computer 1. Here, in a preferred embodiment, the laser processing trace is circular and has a diameter of 90 to 400 μm. Preferably, the diameter is 90 microns. That is, the inclined holes formed on the washing needle are round holes with the diameter of 90 microns. In other embodiments, the laser machining trajectory may be an ellipse, and the angled hole formed in the irrigation needle is an elliptical hole.
Step c: adjusting a laser beam for aiming to a designated position of an irrigation needle head to be processed, and adjusting the direction of the laser beam and the axial direction of the irrigation needle head to form an angle, wherein the range of the angle alpha is as follows: alpha is more than or equal to 10 degrees and less than 90 degrees.
In the step, the distance between the designated part and the tip of the washing needle head is 0.07-16 mm. The designated position is the position of the inclined hole formed on the needle tube of the washing needle. Wherein 0.07 mm is the minimum wall thickness of the existing irrigation needle. 16 mm is the length of the threaded portion of the file, corresponding to the maximum distance from the side opening of the irrigation needle to the tip. Generally, the closer the angled holes are to the tip, the better the effect of the liquid backwash. Therefore, preferably, the distance from the designated position to the tip of the washing needle can be 0.07-10 mm. More preferably, the distance from the designated position to the tip of the washing needle head can be 0.07-5 mm.
In addition, a certain angle is required between the direction of the laser beam and the axial direction of the washing needle (axial direction of the needle tube). Specifically, the wash needle is fixed to an auxiliary workpiece on the table 5, and a desired angle α is obtained by adjusting an angle between a surface of the auxiliary workpiece and a horizontal plane. Preferably, the angle α between the direction of the laser beam and the axial direction of the needle is in the range of 40 ° α 70 °. In an exemplary embodiment, the angle between the direction of the laser beam and the axial direction of the needle may be 45 °, as shown in fig. 3, where the direction of the laser beam is vertically downward and the axial direction of the irrigation needle 11 forms a 45 ° angle with the laser beam. In other embodiments, such as the root canal has an undercut, an internal absorption, and an incomplete opening of the pulp angle, the angle α between the opening direction of the inclined hole and the axial direction of the needle is in the range of 10 ° to 20 °, and the flushing effect of the returned flushing fluid is better.
Finally, step d: and starting the laser device, and forming an inclined hole on the tube wall (side wall) of the needle tube of the flushing needle head towards the closed end. The angle between the direction of the oblique hole (the direction of the hole) and the axial direction of the needle is equal to the angle alpha. Preferably, the number of the formed oblique holes may be 1 to 6. In a preferred embodiment, 1 diagonal hole may be formed. In another preferred embodiment, the number of angled holes 14 is 2 or 4, and the location of 2 or 4 angled holes may be on both sides of the irrigation needle tube wall 3. In a further preferred embodiment the number of angled holes 14 is 3 or 6, and the positions of 3 or 6 angled holes may be on three side walls of the irrigation needle tubing wall at 120 degrees to each other.
As described above, the present invention originally proposes a method of manufacturing a reflux irrigation needle. The method of the present invention has laser beam controlled by computer system to punch hole in the side wall of the needle tube of the flushing needle, and the hole may be designed and controlled precisely. That is, the method of the invention can form water outlets with different quantities, sizes and directions on the side wall of the needle tube of the washing needle head according to clinical requirements, and can also carry out personalized manufacture according to different root canal shapes. This allows the infected necrotic tissue and debris from the root canal to be flushed out of the coronal canal rather than out of the apical foramen.
The invention adopts laser to punch holes on the material of the washing needle head, the quality of the punched small holes is good, and especially when a plurality of same small holes are punched, the sizes and the shapes of the small holes can be ensured to be uniform, the punching speed is high, and the production efficiency is high. And the diameter of the small holes can be as small as tens of microns, and the processing requirements can be completely met.
Fig. 4 shows a reflux-type syringe needle 11 manufactured by the method of the present invention, wherein the tip 12 of the syringe needle 11 is a closed end. The other end 16 of the irrigation needle 11 opposite the closed end is typically removably attached to a syringe 17 (shown in fig. 3) by a needle hub. The wall (outer wall) 13 of the irrigation needle 11 is opened with an inclined hole 14 towards the closed end 12, and the angle between the direction (opening direction) 15 of the inclined hole 14 and the axial direction of the needle is equal to the angle α.
As described above, the tube wall 13 of the irrigation needle 11 is provided with the inclined hole 14, so that the liquid flows into the tube wall 13 of the irrigation needle 11 to the closed end 12 and then is blocked from flowing backwards and is emitted through the inclined hole 14, the emitting direction of the liquid is controlled by the opening angle of the inclined hole 14, and the liquid backflow effect is achieved by the inclined hole diversion effect.
The reflux-type flushing needle head manufactured by the method controls the flow direction of flushing liquid by changing the opening angle of the inclined hole of the needle head, can generate larger flushing pressure and flow speed, and can meet the requirement of large-scale, quick and safe flushing, thereby greatly improving the cleaning degree and the treatment effect in the root canal.
The invention is applied to the root canal treatment, and can obviously improve two most important effects in the root canal flushing. The first are chemical effects, i.e., chemical destruction or inactivation of biofilm, killing of microorganisms and inactivation of endotoxins, dissolution of pulp tissue remnants, dentin smear layer, etc. Since this effect can only be achieved by chemically active solutions (such as sodium hypochlorite). It has been reported in the literature that a particular bacterial biofilm requires 15 minutes of immersion in a 6% strength sodium hypochlorite solution to dissolve. In the narrow root canal space, the sodium hypochlorite solution can play the most role only by continuously supplementing and updating. The irrigation needle head of the present invention produces an effective reverse flow of water, increasing the renewal efficiency of the irrigation fluid in the root canal, especially the apical portion of the root canal (apical to coronal renewal) while maintaining a minimum pressure at the apical site. The second is the mechanical effect, i.e., the application of force by the irrigant, mechanically disrupts, peels away and removes microorganisms/biofilm in the root canal system, pulp tissue remnants and dentinal debris, etc. The mechanical effect may be applied by a rinsing fluid (e.g., water, a solution for disinfecting or sequestering a drug, etc.). In the flushing process, the solution flowing reversely and at high speed generates impact force and friction force on the root canal wall, so that the contents such as bacterial biofilms, pulp tissue residues, dentin debris and the like are separated from the root canal wall and discharged to the coronal direction, and finally the root canal is filled with clear flushing liquid with a disinfection function. Since infection control is a critical factor in root canal treatment, drying and filling of the root canal can be performed at this time. Under the conditions of not adding any equipment and not needing specific training for dentists, the effect of single-method root canal treatment is ensured, and the comfortable, efficient and safe treatment concept is also met.
The reflux irrigation needle produced by the method of the present invention is not limited to the inside of a root canal, and is applicable to many fine tissue structures such as the crown and periodontal pockets. The reverse flushing can discharge the infected necrotic tissues out of the body, and promote the healing of the wound. The pressure of the flushing fluid is not released to the deep part of the tissue, thereby avoiding causing adverse consequences such as acute pain, tissue injury and the like, relieving the tension of the patient to a certain extent and leading the doctor-patient relationship to be more harmonious.
It will be apparent to those skilled in the art that the above embodiments are merely illustrative of the present invention and are not to be construed as limiting the present invention, and that changes and modifications to the above described embodiments may be made within the spirit and scope of the present invention as defined in the appended claims.
