The bottom of the bone is close to the sinus or the stenosis of the humerus. It is known that the alveolar bone is very thin here. The conventional dental drill bit will destroy the alveolar lumbar plate to make a fine bone fracture or a nasal w film perforation. The time of the original dental surgery will be prolonged. For example, in the age-old surgery, 'traditional motor drive, 'tooth continuation, the tip of the thread will have a high degree of metastasis, so the patient will be sharp when receiving the treatment. The noise is so horrible that it can't be treated well. 'Moreover, there will be a wish to make the drill method go smoothly: in addition to this, the traditional motor-driven sorghum Saki Ma reconciliation, which is intended to be filled in the teeth. Inside _ a little scale, into the teeth away from the hole 3 M394098 So in the tool used for tooth writing or dental surgery, there is a combination of ultrasonic host, mobile phone and special bone knife, because the ultrasonic host can output pure Ultrasonic inspection, through the special _ purely will Wei machine, the high-frequency ultrasonic vibration, so that the contact of the tissue cells in the water vaporization, protein ammonia bond break 'lie will need _ 织 织 职 , , The difference in the frequency of the paste vibration can effectively deal with the hard tissue without damaging the soft tissue, but at present, the bone money used by the ultrasonic host is commonly used in the hemispherical design or on the end of the cutting operation. Surface treatment (such as di_nd coating) to help cut the grinding, this design with ultrasonic compared to the conventional motor-driven equipment, has better performance in terms of convenience and comfort, but still has insufficient cutting force in practical use. The problem exists' so it is necessary to provide a more practical ultrasonic cutting tool. ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ ’ 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本[New content] Before the decision, the main money is provided with a kind of ultrasonic gift knives, which is designed to solve the various problems of the fascination. Tooth = \ purpose, this creation provides an ultrasonic cutting tool Na-body dental surgery, an ultrasonic main device connection, including:, H is fixed on the mobile phone of the ultrasonic main device; - M394098 a shank portion extending from the other end of the body portion and having a linear or curved structure, the inside of which is provided with a coolant passage for the water supply to flow, and the water supply for the effluent hole to flow out; and - the tip end portion, The end portion of the blade arm portion is formed in a cylindrical shape, and has a first end and a second end. The outer peripheral surface of the blade tip portion is annularly equidistant to form a plurality of grooves. The present invention further provides an ultrasonic cutting tool that corrects the diameter of the first end of the tip portion to be greater than the straightness of the second end. For the present invention, the preferred embodiments of the scales and the accompanying drawings are described in detail below. [Embodiment] Referring to Fig. 1 'Fig. 1 is a schematic diagram of the structure of the ultrasonic cutting tool of the present invention, the ultrasonic cutting tool 1G is used in the preparation of dental cavity or dental surgery' and the ultrasonic_ The cutter 1G is connected to the ultrasonic main device, and the ultrasonic wire is provided to provide a high frequency neon touch signal of the ultrasonic wave and the water liquid, and the super chopper main device is connected to the ultrasonic mobile phone by a pipeline, and the ultrasonic mobile phone can be Accepting the high-frequency recording signal of the water liquid and the ultrasonic main device and turning it into high-frequency vibration. Therefore, the ultrasonic cutting tool 1G is connected to the ultrasonic mobile phone, and the high-pitched sound of the _ sound wave, the ultra-sonic domain is purchased. The high-frequency movement of the cutter 10 back and forth, The surgical field can be used for vertical cutting or horizontal side cutting. The ultrasonic domain cutter 1G includes a body 邛11, one end of which is inserted and fixed on the mobile phone of the ultrasonic main device; The blade arm portion 12 extends from the other end of the body portion U and has a linear or curved structure. For example, a curved structure means that an angle is obtained at an appropriate position of the shaft 12, and the angle may be -❹, It can be used with the patient's mouth to facilitate the dentist's treatment of the tooth. The inside of the device is provided with a coolant channel i2i and a water outlet hole (2). The coolant channel 121 is used for the water supplied by the ultrasonic mobile phone, and the water is discharged. The hole 122 is located at the tail end 1211 of the coolant channel 121 for the outflow of water liquid. Due to the high frequency vibration of the ultrasonic mobile phone, the ultrasonic cutting tool generates high heat, so the water flows through the coolant. Channel 121 to take away some of the high heat generated by the ultrasonic cutting tool 1G, in other words, can provide - cooling function, and the outlet of the water outlet 122 can be washed in the preparation of the hole or the dental The hard group under the surgery The hard tissue under the cutoff does not remain in the socket of the tooth; and the tip end portion 13 is disposed at the end portion 123 of the arm portion 12 and has a cylindrical shape with a first end 135 and a second end 136, please refer to FIG. 2 together. FIG. 2 is a cross-sectional view of an embodiment of the blade tip portion of the cross section AA of FIG. i, and the outer peripheral surface 131 of the blade tip portion 13 is formed by a plurality of grooves in an annular equidistant manner. The number of the grooves 132 may be 3 to 12, and the number of the grooves 132 is 5 in this embodiment. The present invention is not limited thereto, and the groove I]] has at least two processes. The face 134, the treatment surface 134 and the outer peripheral surface 131 are joined to form two blade portions 133, so the two blade portions 133 have two angles Θ1 and Θ2'. In the present embodiment, the two angles Θ1 and θ2 are optimal. In other embodiments, 'Θ1 and Θ2 can be right angles or an obtuse angle and an acute angle. Please refer to FIG. 3, which is an embodiment in which both Θ1 and Θ2 are right angles. Please refer to FIG. 4, that is, M394098 is Θ1. The embodiment is an obtuse angle and the Θ2 is an acute angle. Therefore, the two angles Θ1 and the specific angle may be an obtuse angle and an acute angle, or both are obtuse angles and right angles. The present invention is not limited thereto, and the grooves 132 are formed on the cutting end portion 13 in a spiral shape for improving the cutting ability. Please refer to FIG. 5 and FIG. 6 for the root canal. When the cutting tool 1 is subjected to the horizontal side by the high frequency vibration of the ultrasonic wave, the spirally equidistant blade portion 133 can effectively provide a stronger, stable and average cutting ability. In this embodiment, the diameter of the first end 135 of the cutting edge portion 13 is larger than the diameter of the second end 136. In other words, the second end 136 of the cutting edge portion 13 is tapered toward the first end 135. Body, the structure can provide more angle and more area contact between the cutting edge portion 13 and the surgical site, and has the effect of reaming, which can effectively raise the cutting ability. Of course, the diameter of the first end 135 can also be equal to For the diameter of the second end 136, please refer to another embodiment shown in FIG. 7, FIG. 8 and FIG. 9. Since the diameter of the first end 135 is equal to the diameter of the second end 136, compared to the foregoing embodiment, The embodiment lacks the effect of reaming, but still provides better cutting ability than the conventional drill bit, so the physician can select the ultrasonic cutting tool of different configurations of the tip 13 according to different situations. The above embodiments are merely illustrative of the principles and functions of the present invention and are not intended to limit the present invention. Therefore, those skilled in the art can make modifications and changes to the above embodiments without departing from the spirit of the present invention.
