Description

Technical Field

[0001] The present invention relates to the technical field of dental instruments, and particularly to a scaler capable of quickly identifying a working edge and a using method thereof. Background Art

[0002] A scaler is a dental medical instrument used for treating periodontal diseases, and its main body is mainly made of high-hardness stainless steel or tungsten carbide. The cutting edge of the working end of some scalers is formed into an inclined design by laser fine grinding (usually the inclined angle is 70°-80°), so that a minimally invasive leveling effect of 0.2 mm - 0.3 mm can be achieved on the root surface by using the working edge. Therefore, the working edge of the scaler can scrape off dental calculus, plaque and infected tissues around the teeth to reduce inflammation and promote periodontal healing.

[0003] Since the working surface of the working end of the scaler has a certain inclination angle relative to the neck (shank), when a dentist uses the scaler on a patient, it is necessary to use the lowest end of the inclined working end (i.e., the working edge) to contact the patient's teeth for scaling work. Therefore, before using the scaler, the dentist needs to visually confirm the direction of the working edge of the scaler (i.e., confirm the position of the lower end of the inclined working surface of the working end), and then perform the scaling work. For example, before using the scaler, the dentist needs to hold the neck of the scaler upright and at the same time place the working end of the scaler at a position level with the line of sight, and then rotate the scaler until the position of the working edge is confirmed, so as to confirm the working direction of the scaler. This way of confirming the working direction of the scaler is time-consuming and laborious, greatly reducing the working efficiency of the dentist.

[0004] In addition, since the working edge of the scaler will be worn during use and needs to be sharpened regularly to ensure the working efficiency, when the scaler has been used for a period of time, the working end of the scaler will gradually become narrower due to sharpening, and at this time it is more difficult to confirm the position of the working edge, that is, it is more difficult to confirm the working direction of the scaler. Therefore, when a dentist uses a worn scaler, it will be more difficult for the dentist to distinguish the working direction of the scaler, thereby increasing the time for confirming the working direction of the scaler and further reducing the working efficiency of the dentist. If the instrument sharpening personnel make a wrong judgment when distinguishing the working edge of the scaler, it will cause unnecessary wear on the non-working side, and the working edge is not sharpened, resulting in instrument loss while not improving the sharpness of the working edge, affecting the scaling effect and even causing the instrument to break.

[0005] Therefore, how to improve the speed of the dentist's confirmation of the working edge (i.e., confirm the working direction of the scaler) during the dentist's work, thereby improving the working efficiency of the dentist, and at the same time improving the accuracy of the instrument sharpening personnel in distinguishing the working edge has become an urgent problem to be solved at present. Summary of the Invention

[0006] The object of the present invention is to provide a scaler capable of quickly identifying the working edge and its using method to solve the problems existing in the above-mentioned prior art.

[0007] To achieve the above object, the present invention provides the following solution:

[0008] In a first aspect of the present invention, there is provided a scaler capable of quickly identifying the working edge, which includes a handle portion and a working end, wherein:

[0009] The working end has a working edge for contacting the tooth surface and a non-working side opposite thereto; and the scaler is provided with an identification portion, and the identification portion is arranged corresponding to the working edge.

[0010] According to an embodiment of the present invention, the identification portion has one of the following structures:

[0011] (a) A structure in which at least a part of the identification portion protrudes from the surface of the peripheral member of the identification portion, that is, having a protruding structure;

[0012] (b) A structure in which at least a part of the identification portion is lower than the surface of the peripheral member of the identification portion, that is, having a recessed structure;

[0013] (c) A structure in which at least a part of the identification portion is flush with the surface of the peripheral member of the identification portion.

[0014] Among them, the above-mentioned peripheral member refers to a part of the member corresponding to the position where the identification portion is arranged. For example, when the identification portion is arranged on the handle portion, the peripheral member refers to the handle portion. When the identification portion is arranged on a part of the handle portion and the neck, the peripheral member refers to the handle portion and the neck. When the identification portion is arranged on the neck, the peripheral member refers to the neck.

[0015] According to an embodiment of the present invention, the identification portion includes an identification layer. Preferably, the identification layer is arranged on the surface of the handle portion. Further preferably, the identification layer has a color that is easy to identify. The identification layer can be arranged on the surface of the scaler by known processes. For example, by spraying process, especially nano-spraying process. The thickness of the coating is not limited, and it can be, for example, 1 - 1000 μm, preferably 50 - 800 μm, more preferably 10 - 500 μm, such as 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, 100 μm, 200 μm, 300 μm, 400 μm, etc. In a certain embodiment, the identification layer has wear resistance and / or corrosion resistance. For example, the wear resistance grade reaches 5H of ASTM D4060 standard. For another example, the identification layer can withstand solvents, especially the corrosion or dissolution of alcohol solvents, that is, the marking material can withstand disinfection treatment.

[0016] According to an embodiment of the present invention, the identification part further includes a groove. Preferably, the identification layer is arranged in the groove. The depth of the groove is 0.001 mm - 0.5 mm, preferably 0.01 mm - 0.5 mm, more preferably 0.02 - 0.45 mm, still more preferably 0.05 - 0.3 mm, such as 0.1 mm, 0.2 mm. The forming process of the groove is not limited. For example, a laser engraving process can be used to embed it into the surface layer of the handle.

[0017] According to an embodiment of the present invention, when the viewing angle is from the working edge to the handle, the depth direction of the groove is in the counterclockwise direction of the length direction of the working edge, and the included angle between the two directions is 40° - 50°. Thereby, it can be avoided that when holding the handle, the holding part completely overlaps with the identification part, thus affecting the identification of the direction of the working edge.

[0018] According to some embodiments of the present invention, the setting position of the identification part is not limited as long as it is convenient for use. In one embodiment, at least a part of the identification part is arranged on the handle. In another embodiment, at least a part of the identification part is located on the neck.

[0019] According to an embodiment of the present invention, the handle further includes a holding part, and at least a part of the identification part does not overlap with the holding part.

[0020] According to an embodiment of the present invention, the corresponding setting includes at least one of the following setting methods:

[0021] (1), The identification part is set to indicate one side of the working edge for directly indicating the position of the working edge;

[0022] (2), The identification part is set to indicate the non - working side position of the curette, thereby indirectly indicating the position of the working edge.

[0023] According to an embodiment of the present invention, the curette includes at least one selected from a first curette, a second curette, a third curette, and a fourth curette. Preferably, the model of the first curette is 5 / 6, and it has a first identification part; the model of the second curette is 7 / 8, and it has a second identification part; the model of the third curette is 11 / 12, and it has a third identification part; the model of the fourth curette is 13 / 14, and it has a fourth identification part. Preferably, each of the first identification part to the fourth identification part is provided with an identification layer of a different color. For example, the first identification part has color A, the second identification part has color B, the third identification part has color C, and the fourth identification part has color D, and colors A - D are different colors. The colors A - D in the present invention are not limited, and preferably international standard color numbers are used. By making the marking color and the working end number uniquely bound through color and model, a system corresponding to color and model is formed. Preferably, international standard color numbers are used. For example, model 5 / 6 corresponds to yellow (Pantone109C), 7 / 8 corresponds to green (Pantone 356C), 11 / 12 corresponds to red (Pantone185C), 13 / 14 corresponds to blue (Pantone 285C), and the color difference tolerance ΔE ≤ 2.0.

[0024] According to an embodiment of the present invention, the neck is located at one end of the handle, and the working end is located at the end of the neck away from the handle. One end of the neck close to the handle is an inverted frustum structure, and the end of the neck away from the handle is a columnar structure. Preferably, the working end is located at the end of the neck away from the handle, and the working end has a working surface. When the neck is perpendicular to the ground, the working surface is inclined relative to the horizontal plane, and the edge on the relatively lower side of the working surface is the working edge.

[0025] According to an embodiment of the present invention, the identification part includes a groove, the groove is opened on the curette, and the groove is arranged corresponding to the working edge; and the groove is filled with an identification layer.

[0026] According to an embodiment of the present invention, the groove is an elongated structure, preferably extending along the length direction of the handle, and at this time it can be called an identification long groove. Preferably, the width of the identification long groove is the same as the width of the small circular surface of the inverted frustum structure of the neck. Preferably, the length of the identification long groove is one-sixth of the length of the handle.

[0027] According to an embodiment of the present invention, the identification long groove is opened at the end of the handle and is parallel to the length direction of the handle; and both ends of the identification long groove are opened on the handle and the inverted frustum structure of the neck respectively.

[0028] According to an embodiment of the present invention, one end of the marked long groove faces the direction of the working edge as an arrow structure, that is, the arrow structure is correspondingly arranged with the working edge.

[0029] According to an embodiment of the present invention, the included angle between the depth direction of the marked long groove and the length direction of the working edge is 40° - 50°, thereby avoiding the marked part being blocked when holding the handle.

[0030] According to an embodiment of the present invention, the neck is a bent structure. The bent structure is not limited and can be any structure known in the art. For example, the structure of the HU-Friedy brand or other similar structures.

[0031] According to an embodiment of the present invention, the included angle between the working edge and the lower half part after bending of the columnar structure of the neck is 70° - 80°.

[0032] According to an embodiment of the present invention, anti-slip patterns are provided on the handle. Preferably, the anti-slip patterns include a plurality of anti-slip small grooves opened on the handle along the circumferential direction of the handle, and several layers of the plurality of anti-slip small grooves are sequentially arranged along the axial direction of the handle.

[0033] In the second aspect of the present invention, a method for using a scaler capable of quickly identifying the working edge is provided. This method includes the scaler capable of quickly identifying the working edge as described above, and it includes:

[0034] S1. Vertically place the handle;

[0035] S2. Place the marked layer flush with the line of sight to quickly identify the position of the working edge;

[0036] S3. Utilize the position of the working edge identified in step S2 to perform scaling work on the patient's teeth with the working edge;

[0037] S4. In step S3, through the included angle between the depth direction of the marked layer and the length direction of the working edge, enable the marked layer to be located between the dentist's thumb and index finger to identify the position of the working edge at any time.

[0038] The present invention has at least the following technical effects:

[0039] The scaler for quickly identifying the working edge provided by the present invention, through the setting of the marked part, can not only enable the dentist to quickly identify the working direction of the scaler, thereby improving the working efficiency of the dentist, but also in some embodiments, by associating the marked part with the model, enable the dentist to quickly distinguish different models of scalers, thereby avoiding confusion of different models of scalers and improving the working efficiency of the dentist. In addition, through the setting of the marked part, the present invention can also increase the teaching efficiency for novice doctors or young doctors during the teaching process.

[0040] In some embodiments, the curette can be more accurately identified. Through a "color + position" dual-coding system, the accuracy of identifying the working end orientation by the working edge direction is increased to 100%.

[0041] In some embodiments, visual misjudgment (such as reflection interference) is avoided by making the marking width greater than the width of the working edge, thereby improving the anti-interference ability of the curette.

[0042] In some embodiments, the ergonomics of the curette is better. By making the marking area at the end 1 / 6 of the length conform to the visual field range when the thumb holds naturally, operation without line-of-sight deviation is achieved.

[0043] In some embodiments, the durability of the curette is better. Through the laser engraving process, it is ensured that the marking does not fade during long-term use, including resistance to friction, high-temperature and high-pressure disinfection, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only provided to better understand the present invention by showing examples of the present invention.

[0059] Those skilled in the art should understand that in this embodiment, the description of "dentist" is only for more conveniently describing the implementation manner of the present invention. It is only an exemplary general concept and does not specifically limit a certain specific person. Referring to Figure 1-8 , in the first aspect of the present invention, a scaler capable of quickly identifying a working edge is provided. The scaler at least includes a handle 1, a neck 4, a working end 7, and a working edge 701, wherein:

[0060] Referring to Figure 1-6 , the neck 4 is located at one end of the handle 1, the working end 7 is located at the end of the neck 4 away from the handle 1. One end of the neck 4 close to the handle 1 is a frustum of a cone structure, and the end of the neck 4 away from the handle 1 is a cylindrical structure. That is, the large circular surface of the frustum of a cone structure is connected to the handle 1, and the small circular surface of the frustum of a cone structure is connected to the cylindrical structure of the working end 7.

[0061] In this embodiment, the handle 1, the neck 4, the working end 7, and the working edge 701 can all be made of a metal material, such as a medical-grade titanium alloy known in the art, which is not particularly limited herein.

[0062] In this embodiment, the connection manners between the handle 1, the neck 4, the working end 7, and the working edge 701 can all be manners known in the art, such as connecting by welding. Or, the handle 1, the neck 4, the working end 7, and the working edge 701 can be integrally formed, which is not particularly limited herein.

[0063] In this embodiment, referring to Figure 1 、 Figure 2 or Figure 4 , both the handle 1 and the neck 4 can be cylindrical structures, and the cross-sectional diameter of the neck 4 is smaller than the cross-sectional diameter of the handle 1.

[0064] In this embodiment, referring to Figure 1-5 , the diameter of the large circular surface of the frustum of a cone structure part of the neck 4 can be smaller than the cross-sectional diameter of the handle 1, and the diameter of the small circular surface of the frustum of a cone structure part of the neck 4 can be equal to the cross-sectional diameter of the cylindrical structure part of the working end 7.

[0065] In this embodiment, referring to Figure 1-5 , a bevel transition structure can be provided at the connection between the handle 1 and the neck 4.

[0066] According to an embodiment of the present invention, referring to Figure 1 、 Figure 2 and Figure 4-7, the working end 7 is located at one end of the neck 4 away from the handle 1. When the end of the neck 4 is perpendicular to the ground, the working surface of the working end 7 is arranged in an inclined manner relative to the ground or the working surface forms a certain inclination angle with the neck 4. The lowest end of the inclined working surface of the working end 7 is the working edge 701, and the working edge 701 is the side that contacts the tooth surface. The included angle between the working surface and the neck 4 on the side of the working edge 701 is 70°.

[0067] In this embodiment, referring to Figure 8 , the overall shape of the working end 7 is not particularly limited and can be any shape known in the art. Exemplarily, for example, it can be a flat cuboid structure, and chamfering treatments are provided at the four corners of the cuboid-structured working end 7. Additionally, the cross-sectional shape of the working end 7 is not limited. Preferably, it is a semi-circular arc structure.

[0068] According to an embodiment of the present invention, referring to Figure 1-6 , a marking portion is provided on the scaler. The marking portion is correspondingly arranged with the working edge 701, that is, the end of the marking portion close to the working end 7 points to the position of the working edge 701, so that dentists and instrument sharpening personnel can quickly identify the position of the working edge 701 (i.e., the direction when the working end 7 works).

[0069] According to an embodiment of the present invention, referring to Figure 1-6 , the marking portion includes a marking long groove 5. The marking long groove 5 is opened on the scaler, and the marking long groove 5 is correspondingly arranged with the working edge 701 (i.e., the end of the marking long groove 5 close to the working end 7 points to the position of the working edge 701). The marking long groove 5 is filled with a marking layer 6.

[0070] In this embodiment, referring to Figure 1-6 , the marking long groove 5 can be a cuboid structure.

[0071] In this embodiment, the marking layer 6 can be a non-toxic nano-scale corrosion-resistant material with color filled in the marking long groove 5, using materials known in the art. For example, known blue nano-cobalt blue materials, green polyaniline nano-materials, white nano-titanium dioxide materials, or brown nano-ferroferric oxide materials in the art can be used, and no special limitation is made here.

[0072] Furthermore, the marking layer 6 can also be a layer of pigment sprayed in the marking long groove 5 through a nano-spraying process known in the art, and then a filling material known in the art that is heat-resistant, corrosion-resistant, transparent, and non-toxic can be filled in the marking long groove 5, such as a transparent filling masterbatch containing anhydrous transparent powder or PEA material, and no special limitation is made here.

[0073] In this embodiment, when the identification layer 6 is filled in the identification long groove 5, one end of the identification layer 6 away from the working end of the scaler can be polished into a shape identical to the appearance of the scaler, so that the integration of the identification layer 6 and the scaler is better and will not affect the use by dentists.

[0074] In one embodiment of the present invention, the above-mentioned nano-scale corrosion-resistant material, transparent filling masterbatch containing anhydrous transparent powder, and PEA material all have excellent corrosion resistance and high-temperature resistance, improving the durability of the identification layer 6. For example, when the scaler is wiped with alcohol for disinfection multiple times, the above materials will not cause excessive corrosion and will not fade, ensuring the normal progress of the subsequent working edge identification work. Another example is that when the scaler is sterilized at a high temperature (135 °C), the above materials will not be damaged, and the normal progress of the subsequent working edge identification work can also be ensured.

[0075] In this embodiment, there is no special limitation on the way of opening the identification long groove 5 on the scaler. It can be opened on the scaler by using the known CNC processing technology in the art, or the position of the scaler that needs to be grooved can be etched by using the known mask spraying process in the art, thereby opening the identification long groove 5 on the scaler.

[0076] In addition, in one embodiment of the present invention, since the scaler models for scaling different tooth positions (such as anterior teeth or posterior teeth) and different tooth surfaces (such as buccal-lingual side, mesial or distal) (such as the 5 / 6, 7 / 8, 11 / 12, and 13 / 14 models of the HU-Friedy brand known in the art) are different, dentists need to frequently replace different models of scalers when scaling different tooth positions of patients. However, the appearances of different models of scalers are very similar. Therefore, when dentists replace different models of scalers, they cannot quickly select the required model of scaler, which is extremely likely to cause confusion and also reduces the work efficiency of dentists. By the above setting of using a colored identification layer 6 or spraying pigments in the identification long groove 5, different models of scalers can be marked with different colors. For example, a yellow identification layer 6 is used in the identification long groove 5 of the 5 / 6 model scaler, or yellow pigment is sprayed in the identification long groove 5 of the 5 / 6 model scaler, and then a green identification layer 6 is used in the identification long groove 5 of the 7 / 8 model scaler, or green pigment is sprayed in the identification long groove 5 of the 7 / 8 model scaler, and so on. Thus, dentists can quickly distinguish the required model of scaler without causing confusion, greatly improving the work efficiency of dentists.

[0077] Meanwhile, when teaching novice doctors or young doctors about curettes of different models, the common memory of colors and different models of curettes can also be utilized to improve teaching efficiency. For example, when novice doctors or young doctors need to learn about curettes of models 5 / 6 and 7 / 8, they can quickly develop the muscle memory and visual reflex of "yellow for model 5 / 6 and green for model 7 / 8", thereby improving teaching efficiency. At the same time, in subsequent internship work, there will be no incorrect selection of different curette models, and it can also ensure the smooth progress and work efficiency of the curettage work.

[0078] According to an embodiment of the present invention, referring to Figure 1-6 , the depth of the identification long groove 5 is 0.2 mm - 0.5 mm, preferably 0.5 mm. The width of the identification long groove 5 is the same as the width of the small circular surface of the inverted frustum structure of the neck 4, and the length of the identification long groove 5 is one-sixth of the length of the handle 1.

[0079] In this embodiment, the length of the handle 1 can be 120 mm, and the length of the identification long groove 5 is one-sixth of the length of the handle 1. Therefore, the length of the identification long groove 5 can be 25 mm.

[0080] In this embodiment, the width of the small circular surface of the inverted frustum structure of the neck 4 can be 2 mm. Therefore, the width of the identification long groove 5 can also be 2 mm.

[0081] According to an embodiment of the present invention, referring to Figure 1-6 , the identification long groove 5 is opened at the end of the handle 1, and the identification long groove 5 is arranged parallel to the handle 1; both ends of the identification long groove 5 are respectively opened at the end of the handle 1 and the inverted frustum structure of the neck 4.

[0082] In this embodiment, referring to Figure 1-6 , since the length of the identification long groove 5 is one-sixth of the length of the handle 1, and the length of the end of the neck 4 is less than one-sixth of the length of the handle 1, when the identification long groove 5 is opened at the end of the handle 1, both ends thereof will protrude from both ends of the end of the handle. Thus, both ends of the identification long groove 5 can be respectively opened at the handle 1 and the inverted frustum structure of the neck 4.

[0083] According to an embodiment of the present invention, referring to Figure 2 or Figure 5 , one end of the identification long groove 5 close to the working edge 701 is an arrow structure, and the arrow structure is arranged corresponding to the working edge 701 (i.e., pointing to the working edge 701).

[0084] In this embodiment, the arrow structure can be an obtuse angle structure, and its included angle points to the working edge 701.

[0085] According to an embodiment of the present invention, referring to Figure 8, it is marked that the included angle between the groove depth direction of the long groove 5 and the length direction of the working end 7 is 40° - 50°, preferably 45°.

[0086] In this embodiment, referring to Figure 8 , since the long groove 5 for marking is a groove structure and is opened on the scaler, the groove depth direction of the long groove 5 for marking is the direction pointing to the center of the cross-section of the scaler handle. The length direction of the working end 7 is Figure 8 the length direction of the working end 7 from left to right in

[0087] In an embodiment of the present invention, when a dentist uses the scaler of the present invention for scaling work, the dentist's finger is very likely to block the marking layer 6, which may lead to the situation that the position of the working edge 701 cannot be confirmed during the work process. Through the above-mentioned included angle setting, the situation that the dentist's finger blocks the marking layer 6 during the work process can be effectively avoided, and then the dentist can always confirm the position of the working edge 701 during the work process, ensuring the smooth progress of the scaling work and further improving the work efficiency of the dentist.

[0088] According to an embodiment of the present invention, referring to Figure 6 , the columnar structure of the neck 4 is a bent structure. In this embodiment, the columnar structure of the neck 4 is a cylindrical structure.

[0089] In an embodiment of the present invention, through the setting of the bent structure, when the neck 4 extends into the patient's oral cavity, the adaptability to the patient's oral cavity can be improved, further ensuring the smooth progress of the scaling work.

[0090] According to an embodiment of the present invention, referring to Figure 7 , the included angle between the working plane of the working end 7 and the lower half part (lower shank) of the bent columnar structure of the neck 4 is 70°. This included angle is the included angle between the direction from top to bottom on one side of the working edge 701 in Figure 7 and the direction from right to left of the working plane of the working end 7 in Figure 7 .

[0091] According to an embodiment of the present invention, referring to Figure 1-4 , anti-slip patterns 2 are provided on the handle 1. Through the setting of the anti-slip patterns 2, the friction between the dentist's hand and the scaler can be increased.

[0092] Preferably, referring to Figure 1-4 , the anti-slip patterns 2 include a number of anti-slip small grooves 3 opened on the handle 1 along the circumferential direction of the handle 1, and a number of layers of the anti-slip small grooves 3 are arranged along the axial direction of the handle 1.

[0093] In this embodiment, referring to Figure 1-4 , the shape of the anti-slip small groove 3 can be an oval structure.

[0094] In this embodiment, with reference to Figure 1-4 , a plurality of anti-slip small grooves 3 can be arranged circumferentially on each layer along the handle 1, for example, 10, and a plurality of layers of anti-slip small grooves 3 can be arranged axially along the handle 1, for example, 8 layers. Among them, those skilled in the art can also adjust the number and layers of the anti-slip small grooves 3 according to the actual situation as long as the anti-slip effect can be achieved, and no special limitation is made here.

[0095] In a second aspect of the present invention, a method for using a curette capable of quickly identifying a working edge is provided. The method includes the above-mentioned curette capable of quickly identifying a working edge, and at least includes the following steps:

[0096] S1. First, the dentist holds the handle 1 with the hand and places the handle 1 vertically (that is, horizontally with the dentist's line of sight).

[0097] S2. Secondly, the dentist rotates along the circumference of the handle 1 until the marking layer 6 is flush with the dentist's line of sight. At this time, the position pointed to by the bottom end of the marking layer 6 is the position of the working edge 701, so that the dentist can quickly identify the position of the working edge 701.

[0098] S3. Then, the dentist can use the position of the working edge 701 identified in step S2 to perform curettage work on the patient's teeth with the working edge 701.

[0099] S4. Finally, in step S3, that is, when the dentist performs curettage work on the patient's teeth with the working edge 701, through the angle between the depth direction of the marking layer 6 and the length direction of the working edge 701, the marking layer 6 can always be located between the dentist's thumb and index finger, avoiding the situation that the dentist's thumb and index finger block the marking layer 6, and at the same time, the marking layer 6 can be located in a prominent position, so that the dentist can also identify the position of the working edge 701 at any time during the curettage work, improving the dentist's work efficiency and ensuring the smooth progress of the curettage work.

[0100] The above-mentioned embodiments of the present invention can be combined with each other and have corresponding technical effects.

[0101] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
