範圍上。光源藉由已可取得的超音波振動能加以增能，所 9 1342764 以不需要額外的能量供源。範例中，一諸如及/或包括一照 明能量線圈之換能器係設置且附接至光源以使光源利用換 能器所轉換的振動能加以增能。範例中，由於齒科嵌件的 連接體部快速地移動，一交流電（ac)電壓產生於照明能量線 5 圈中，照明能量線圈係串聯式連接光源（譬如發光二極體 (LED))以提供發光用的能量。其他實施例中，可使用任何 其他的適當換能器來將振動能轉換成一發光用的能量。此 處所用的“光源”可包括一個或不只一個光源。 第1圖顯示一包括一超音波齒科工具10之超音波齒科 10 單元，超音波齒科工具10經由一纜線12附接至一電能&流體 供源14。纜線12包括一用於自電能&流體供源14攜載流體至 超音波齒科工具10之導管及用於自電能&流體供源14攜載 電訊號至超音波齒科工具10之導線。超音波齒科工具10包 括一手持件200及一插入手持件200内之嵌件100。可從第1 15 圖看出，一光源101已經在大致緊鄰於一梢部102之其遠端 附近與嵌件100整合。另一實施例十，複數個光源係在遠端 附近與嵌件100整合。其他實施例中，光源可包括兩或更多 個燈光（諸如第10圖所示的LED 151及161)。其他實施例 中，光源可能未與嵌件整合，而是非整合式附接至嵌件及/ 20 或手握柄，或只有一個光源與嵌件整合而其餘則否。 現在參照第2及3圖，齒科嵌件100包括位於其遠端之梢 部102及一位於其近端之超音波換能器108。梢部102係經由 一可能呈現一軸的形式之連接體部103耦合至換能器108。 梢部102可能可移除式附接至連接體部103，故可依據所需 10 要的應用來更換梢部。並且，脫離了超音波齒科嵌件的其 餘部分之後，梢部102當移除時可加以棄置或以蒸汽進行壓 熱處理，或以其他方式消毒。譬如，可利用皆得自GE塑料 (GE Plastics)之諸如身為非晶系熱塑性聚醚醯亞胺的 ULTEM®，或身為聚碳酸酯與聚對苯二曱酸丁二酯之複合 物的Xenoy®樹脂，或身為聚碳酸酯與間苯二曱酸對苯二甲 酸樹脂（isophthalate terephthalate resorcinol resin)的共聚物 之Lexan®塑料等高溫塑料或任何其他的適當塑料或複合 物’來製造梢部102。亦可利用諸如不銹鋼等金屬或金屬合 金來製造梢部。此處所用的“塑料’’係概括代表諸如樹脂等 合成聚合材料。 連接體部係由諸如不錄鋼等適合傳輸超音波振動之材 料製成。利用連接體部將換能器1 〇 8產生的超音波振動輸送 至梢部102。換能器1〇8譬如可藉由軟銲、溶接、雷射炫接 及/或任何其他的適當方法附接至連接體部1 ^孽如，連 接體部103與換能器1〇8之間的接合部可為利用一包括無鎘 銀銲料及高溫硬銲助劑之硬銲化合物所形成之硬銲接合 部。 當連接體部亦用來產生一圍繞於連接體部的至少一部 刀之照明此里線圈中的電壓時，連接體部較佳係由一具有 磁導率且較佳具有良好磁導率之材料製成。範例中，17 4 PH不錄鋼;^但適合傳輸超音波㈣亦具有溫和的磁性。因 此，174 PH不銹鋼形成的連接體部將藉由在安裝於一照明 能量捲軸126上之照明能量線圈内快速移動（譬如25他或 1342764 更快）而在照明能量線圈上產生一交流(ac)電壓。雖然第2及 3圓中只顯示照明能量捲轴丨26的一端，如同參照第6及7圖 所示，在所描述的實施例中，照明能量捲軸126實際上係包 套住連接體部103大部份。 5 連接體部103上已安裝有一亦由諸如不銹鋼等金屬製 成之環狀扣環1】1 β扣環ill具有一連接部113，連接部 中形成有一概呈圓柱形腔穴以強迫配合關係來接收連接體 部103的一對應部分。扣環固定式附接（譬如鉚扣）至連接體 部103使其既不旋轉亦不沿著連接體部的軸線作側向移動。 10 超音波齒科嵌件100亦包括可由高溫樹脂製成之手握. 柄104。譬如’手握柄104可利用諸如得自孟山都公司 (Monsanto Company)的 SANTOPRENE®，或用來建造某些 梢部所使用的材料等熱塑性彈性體，或藉由任何其他的適 當材料製成。可在經由照明能量捲軸126將照明能量線圈及 15光源101安裝在連接體部丨〇3上之後藉由射出成型形成手握 柄 104。 其他實施例中’手握柄104可為一單件式手握柄，其安 裝在照明能量捲軸126上’而藉由使其在照明能量捲軸126 上方滑動以與連接體部103呈現一圍繞關係。其他實施例 2〇中，可使用多件式手握柄。範例中，一兩件式手握柄可在 照明能量捲軸126上方加以超音波熔接合併。單件或兩件式 手握柄譬如可由 ULTEM®、SANTOPRENE®、Xenoy® 或 Lexan®或其他適當的樹脂塑料製成。 手握柄104具有一概呈圓柱形形狀，且配合在照明能量 12 1342764 捲轴126上方並（譬如經由直接射出成型在照明能量捲轴 ⑶上）固定在位置中。手握柄⑴4亦在如處配置有光源 ΚΠ(譬如LED)之一側上具有一輕微突起部％。其他實施例 中，可能未使用扣環111。 / 口考似賴大。刚的另—側上之其外表面，手握柄 1〇4具有-輪廓且具有-輕微凹形區1〇7,使其能夠容易被 -齒科執業者所簡。手握柄刚上在其外表面亦形成有複 10 數個凸塊1()5(亦即如第2圖所示的條紋式突部）以進一步利 於齒科執業者㈣該裝置。部分可能甚至具有人體工學設 計。所描述的實施例中，一線性溝槽（譬如一通路）110係形 成於梢部102上以輸送流體（譬如水）及/或空氣至患者的牙 銀或牙齒。 梢部可能呈現除垢器（scaler)、齒内治療娃(end〇d〇ntic dental file)、鑽器、或其他用來作牙周治療的工具之形式。 15梢部亦可由金屬或塑料製成，如上述。其中部分亦可具有 輸送流體及/或空氣之能力。 扣環111上形成有一開口 112以自手持件2〇〇接收流 體。流體可經由梢部102基底上所形成之線性溝槽11 〇離 開。其他實施例中’嵌件可在其梢部102端點上具有一開口 20或包含一外部管以使流體能夠離開嵌件。並且，取而代之， 一用以將流體施加至口部之開口係可形成於捲線轴或手握 柄上。 譬如，換能器108可包括相對於彼此平行排列之薄錄板 的堆積體。因為換能器108在齒科工具中產生超音波振動， 13 換能器108亦可稱為馬達。一實施例中，薄鎳板可包括16個 身為90%鎳錳(NiMn)之層疊狀鎳合金條。鎳板可譬如利用 一包括無鎘銀銲料及高溫硬銲助劑之硬銲化合物在兩端以 一硬銲接合部接合在一起。圖示的嵌件1〇〇係為一磁致伸縮 性嵌件，其中當手持件中的一線圈（譬如線圈238，如第12 圖所示）利用來自纜線的電訊號加以增能時鎳板1〇8可超音 波式振動。其他實施例中，超音波齒科嵌件可使用一壓電 換能器’如同歐洲常用的方式。 嵌件100上安裝有一〇環106以接合及壓抵住手持件2〇〇 内表面藉以形成一水密式密封。對於具有一可旋轉式轉子 頭的手持件’ 0環106可接合轉子頭使得超音波齒科嵌件與 轉子頭一起旋轉。 操作期間’薄鎳板108的堆積體係以與堆積體回應手持 件200的線圈所引發激勵的自然頻率相等之一頻率而振 動。嵌件放置在手持件中及電能供源接通之後，操作者調 整電能供源的頻率直到抵達共振頻率，亦即嵌件的自然頻 率為止。或者，自動調整單元一旦接通時即可自動地鎖定 欣件共振頻率。在此時’堆積體開始振動。堆積體的此振 動係經由連接體部103放大及傳輸至梢部丨02。可包含任何 放大的手段。美國使用的超音波嵌件通常設計為以25 kHz 或30 kHz頻率振動。 回應於薄鎳板108的堆積體之超音波振動，連接體部的 梢部係產生振動（譬如連接體部1〇3軸線的快速來回動作）。 範例中’轴線方向的振動可能依據諸如振動頻率、連接體 1342764 部103使用的材料、連接體部1〇3的長度等因素及類似因素 而介於0 00125公分(cm)到0.00375公分之間。 現在參照第4及5圖，梢部具有一長形推拔部115，及一 圓柱形介面部114(“基底”）。可從第5圖看出，推拔部115為 5曲線狀。推拔部115具有一圓形橫剖面且其直徑從抵靠住介 面部114的端點（“近端”)至梢部另一端（“遠端”)逐漸減小。遠 端係在齒科程序期間施用至患者的牙齦/牙齒。 可從第4圖看出，圓柱形介面部丨η具有在嵌件1〇〇軸線 方向中形成之線性溝槽11〇。在所描述的實施例中，移行經 10過照明能量捲軸126之流體係經由線性溝槽110離開。其他 實施例中’梢部可穿設有一小通路，以將水或其他流體供 應至作業中之口中的區域。 梢部102可與連接體部1〇3形成為單一整合件。其他實 施例中’梢部可有一螺紋部附接至介面部以接合連接體部 15 上所形成之一螺紋式開口（如第6Β圊所示）。利用此螺紋式 接合’可將梢部製成可移除式《此可移除能力將使梢部成 為在單一患者使用過後即予更換之可棄式梢部。其他實施 例中’可移除式梢部亦可壓力式配合至連接體部上之—對 應開口内。 20 現在參照第6Α及7圖，連接體部103上亦在其遠端附近 形成有一圓形溝槽138。一 Ο環136坐接在溝槽138中。當照 明能量捲軸126安裝在連接體部103上時，Ο環136在連接體 部10 3與照明能量捲轴12 6之間提供一密封以防止不良的流 體洩漏。 15 1342764 照明能量捲軸126可形成為單件，並可滑移至連接體部 及/或扣環111上且與其鉚扣/壓力式配合。 扣環111具有一概呈圓柱形形狀且其上形成一連接部 113，連接部113配合在連接體部103的一對應圓柱部上方。 5 用以從手持件接收流體之兩個開口 112係形成於連接部113 的相對側上。扣環111上已與連接部113相鄰地形成一用以 坐接外部0環106之圓形溝槽120。 在遠端上，扣環111上係形成有面對彼此之一對握持元 件132。各握持元件具有一端部且此端部往内朝向另一握持 10 元件的端部突起。連接體部103上形成有一對凹部139以接 收握持元件的突起端部使得握持元件132鉚扣在凹部139 内。藉此接合時，所顯示實施例的扣環111係鎖定至連接體 部103，相對於其既不旋轉亦不側向移動。扣環111上亦形 成有圓形凸緣121、124及一圓形溝槽122。圓形溝槽122係 15 用於坐接一 Ο環134。 可從第6A及7圖看出，照明能量線圈99係捲繞在照明能 量捲軸126周圍，照明能量捲軸126對於連接體部103呈現一 圍繞關係加以安裝。照明能量捲軸126譬如可由諸如 ULTEM®等高溫塑料或任何其他的適當材料製成。照明能 20 量線圈99所產生的電壓量係依據諸如線圈彎圈數、照明能 量線圈99相對於連接體部103的位置、連接體部運動的速度 及頻率、連接體部使用的材料等因素及類似因素而定。 範例中，當照明能量線圈較佳由18號銅線製成且具有 多個彎圈而連接體部較佳由17-4 PH不銹鋼製成時，可藉由 16 1342764 25 kHz的振動頻率產生峰值至峰值具有約1到約〗〇伏特，較 佳約1到約5伏特之間的電壓訊號。熟習該技術者瞭解所產 生電壓的量值將隨著彎圈數及/或振動頻率增加而增大。 並且，所顯示的實施例中，可隨著照明能量捲軸126(及 5照明能量線圈99)安裝成為比起距離供梢部1〇2附接之遠端 更靠近連接體部103上的節點，而使電壓增加。節點係為連 接體部上的縱向波量值接近於零且縱向應力具有最大值之 處，在第6Α圖中可為握持元件132附接至連接體部1〇3之地 點（亦即凹部139)。 10 可從第6Α及7圖看出，照明能量捲軸126上係形成有一 框&141及一可在其上安裝LED 1 〇 1之座位142。並且，照明 能量捲轴126上形成有一凸緣143及一概呈圓柱形室144，其 間安裝有照明能量線圈99。概呈圓柱形室144上形成有一凸 緣145。照明能量捲軸126亦包括一附接至室144之環段 15 146 °當超音波齒科嵌件1〇〇已經組裝時，環段146抵靠住扣 環111的凸緣121。 照明能量捲軸126上形成有遠離環段146之一管部 ’管部M0包套住接近梢部1〇2之連接體部1〇3部分。所 描述的實施例中，流體係經由環段146進入照明能量捲軸 2〇 126 ’並經由管部140離開照明能量捲軸126。 第6B圖的超音波齒科嵌件大致與第6A圖的超音波齒 科嵌件100相同且其差異在於：梢部1〇2,在其介面部114,附 接有一螺紋部109’以接合形成於一連接體部103,的一遠端 上之一螺紋式接收部（“接合部”或“螺紋狀螺絲攻”)】19,。類 17 似於超音波齒科嵌件100’第6B圖的超音波齒科嵌件具有一 安裝在一捲軸126’上之光源101，（譬如一LED)。一照明能量 線圈99,係安裝在捲軸126’上且電性耦合至光源1〇1’使得照 明能量線圈99,將超音波振動能轉換成光源101’所使用之電 能以供發射《第6B圖中，一手握柄104’至少部份地包套住 捲軸126’及照明能量線圈99’。 可更換式梢部102,可由金屬（譬如不銹鋼）或塑料（譬如 ULTEM®)製成。因為梢部1〇2,具有很小直徑，其如果施加 太多超音波振動則易破裂。另一方面，如果施加不足的超 音波振動’超音波齒科工具可能無法有效工作。因此，連 接體部1G3’及梢部1Q2’可能設計成將—適當程度的振動施 加至梢部。因為塑料梢部比金屬梢部更可能破裂，在連接 體σ[Π03上使用擊吸收機構來降低對於塑料梢部的衝 擊。 連接體部103，u 上形成有螺紋狀螺絲攻119,以螺入梢部 102’。“螺絲攻”在下5 μ

電壓訊號’故其只在一半時間發射光。然而，因為LED 151 以超音波頻率（譬如25kHz)切換關斷及接通，LED的此快速 切換一般不被人眼所察覺’而LED 151將似乎呈現連續接 通。其他實施例中，光源101可為任何其他適當的光發射裝 10 置，諸如一白熾燈（譬如鹵素燈泡）。 在第9圖的光發射電路中’ 一齊納二極體（zener diode)150並聯式連接至LED 151。一電阻器152連接於照明 能量線圈99與齊納二極體150之間，而一電阻器154連接於 齊納二極體150與LED 151之間。齊納二極體150係鉗位住 15 (clamp)電壓使得LED 151所見的電壓差不會升高超過一特 定的預定電壓。利用此方式，即便照明能量線圈99開始產 生更高電壓，LED 151的亮度可保持大致均勻。譬如，齊納 二極體150可將電壓鉗位在5伏特(V)，使得led 151所見的 電壓不大於5V。 20 第10圖中’一 LED 161以反向平行關係與LED 151連CittT U BACKGROUND OF THE INVENTION Dental surgeons use ultrasonic dental tools (instruments) for orthodontics and procedures such as descaling, periodic treatment, root canal treatment, and the like. An ultrasonic (4) tool typically includes a handpiece that is coupled at one end (i.e., near-end) to a "power source" and a fluid source via a line. The lanyard includes a hose for providing a fluid (such as water) and a conductor for supplying electrical energy. 5 ‘The other end of the handpiece (i.e., a distal end) has a predetermined replacement insert Μπ, which is replaced by a welter-like expander transducer. The transducer extends from the proximal end of the insert to the center of the center. - Ultrasonic vibrating tip is one of the pieces of the mountain from the insert. Because the mouth is a small space for work, it extends. It is still difficult to clearly see all areas of the mouth. When there is no under the condition of dental: when the range of the guard is clearly seen, it is more likely to be a painful slippery industry: the frequent presentation of ultrasonic vibration (4) has a significant damage to soft tissue (such as gum tissue). Causes bleeding and pain. ” = When the dental practitioner leans close to the patient to work in a confined space within the mouth, the dental practitioner hangs the large, focused light above the working range when using the ultrasonic dental tool in the patient's mouth. The system is often hindered. The range of sudden darkening is more difficult to work accurately in it. It will produce small slips and wounds. Therefore, it is necessary to provide a light that can bring light directly into the working range (ie, the patient's mouth. Ρ) Acoustic tooth tool. If an energy source available in an existing ultrasonic tooth tool can be used to provide this light, the circuit complexity and energy requirements can be reduced.

I: Embodiment 3 20 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In an exemplary embodiment of the present invention, an ultrasonic dental implant has at least one integrated light source such as a light emitting diode (LED), thereby allowing a tooth The practitioner can project light onto the working range while applying a tool to the teeth. The source is energized by the available ultrasonic vibration energy, which does not require additional energy to supply. In an example, a transducer such as and/or including a lighting energy coil is disposed and attached to the light source to energize the light source with the vibrational energy converted by the transducer. In the example, since the connecting body of the dental insert moves rapidly, an alternating current (ac) voltage is generated in five circles of the illumination energy line, and the illumination energy coil is connected in series to a light source (such as a light emitting diode (LED)). Provide energy for illuminating. In other embodiments, any other suitable transducer can be used to convert the vibrational energy into a luminous energy. The "light source" used herein may include one or more than one light source. 1 shows an Ultrasonic Dental 10 unit including an ultrasonic tooth tool 10 attached to a power & fluid supply 14 via a cable 12. The cable 12 includes a conduit for carrying fluid from the electrical energy & fluid supply 14 to the ultrasonic dental tool 10 and for carrying electrical signals from the electrical energy & fluid supply 14 to the ultrasonic dental tool 10 wire. The ultrasonic dental tool 10 includes a hand piece 200 and an insert 100 that is inserted into the hand piece 200. As can be seen from Figure 15, a light source 101 has been integrated with the insert 100 near its distal end substantially adjacent to the tip 102. In another embodiment, a plurality of light sources are integrated with the insert 100 near the distal end. In other embodiments, the light source can include two or more lights (such as LEDs 151 and 161 shown in Figure 10). In other embodiments, the light source may not be integrated with the insert, but rather be non-integratedly attached to the insert and / 20 or the handle, or only one light source integrated with the insert and the remainder. Referring now to Figures 2 and 3, the dental implant 100 includes a tip portion 102 at its distal end and an ultrasonic transducer 108 at its proximal end. The tip 102 is coupled to the transducer 108 via a connector portion 103 that may take the form of a shaft. The tip 102 may be removably attached to the connector body 103 so that the tip can be replaced depending on the desired application. Also, after being removed from the remainder of the ultrasonic dental implant, the tip 102 can be disposed of or otherwise heat treated by steam or otherwise sterilized. For example, it can be obtained from GE Plastics, such as ULTEM®, which is an amorphous thermoplastic polyether phthalimide, or a composite of polycarbonate and polybutylene terephthalate. Xenoy® resin, or a high temperature plastic such as Lexan® plastic or a copolymer of any other suitable plastic or compound that is a copolymer of polycarbonate and isophthalate terephthalate resorcinol resin Part 102. Tips can also be made from metal or metal alloys such as stainless steel. As used herein, "plastic" generally represents a synthetic polymeric material such as a resin. The connecting body is made of a material suitable for transmitting ultrasonic vibrations such as non-recording steel. The transducer 1 〇 8 is produced by the connecting body portion. The ultrasonic vibration is transmitted to the tip 102. The transducer 1〇8 can be attached to the connecting body portion by soldering, soldering, laser splicing, and/or any other suitable method. The joint between the portion 103 and the transducer 1〇8 may be a hard welded joint formed by a brazing compound including cadmium-free silver solder and a high-temperature brazing aid. The connecting body is also used to generate a joint. When at least one of the knives surrounding the connecting body illuminates the voltage in the coil, the connecting body is preferably made of a material having magnetic permeability and preferably good magnetic permeability. In the example, 17 4 PH does not record steel; ^ but suitable for transmitting ultrasonic waves (4) also has mild magnetic properties. Therefore, the connecting body formed by 174 PH stainless steel will move quickly by the illumination energy coil mounted on an illumination energy reel 126 (such as 25 He or 1342764 is faster) while lighting An alternating current (ac) voltage is generated across the measuring coil. Although only one end of the illumination energy reel 丨 26 is shown in the second and third circles, as shown in reference to Figures 6 and 7, in the depicted embodiment, the illumination energy reel 126 is actually wrapped around most of the connecting body 103. 5 The connecting body 103 has been mounted with an annular buckle 1 also made of metal such as stainless steel. The β-ring ill has a connecting portion 113. A substantially cylindrical cavity is formed in the connecting portion to force a mating relationship to receive a corresponding portion of the connecting body portion 103. The buckle is fixedly attached (such as a rivet) to the connecting body portion 103 so that it does not rotate or follow The axis of the connecting body is moved laterally. 10 The ultrasonic dental implant 100 also includes a handle that can be made of a high temperature resin. The handle 104 can be utilized, for example, from the Monsanto Company. The SANTOPRENE®, or a thermoplastic elastomer used to build some of the materials used for the tips, or by any other suitable material. The illumination energy coil and the 15 light source 101 can be mounted in connection via the illumination energy reel 126. Body 丨〇 3 The handle 104 is then formed by injection molding. In other embodiments, the 'hand grip 104 can be a one-piece handle that is mounted on the illumination energy reel 126' by being placed over the illumination energy reel 126 Sliding to assume a surrounding relationship with the connecting body 103. In other embodiments, a multi-piece hand grip can be used. In an example, a two-piece hand grip can be ultrasonically welded over the illumination energy reel 126 and A one-piece or two-piece handle can be made of ULTEM®, SANTOPRENE®, Xenoy® or Lexan® or other suitable resin plastic. The handle 104 has a generally cylindrical shape and is fitted with illumination energy 12 1342764. Above the reel 126 and (for example via direct injection molding on the illumination energy reel (3)) it is fixed in position. The handle (1) 4 also has a slight projection % on one side of the light source ΚΠ (such as an LED). In other embodiments, the buckle 111 may not be used. / Oral test is like a big one. On the outer surface of the other side, the handle 1〇4 has a contour and has a slightly concave area 1〇7, making it easy to be simplified by the dental practitioner. The handle is also formed on its outer surface with a plurality of bumps 1 () 5 (i.e., stripe projections as shown in Fig. 2) to further facilitate the dental practitioner (4). Some may even have an ergonomic design. In the depicted embodiment, a linear groove (e.g., a passage) 110 is formed on the tip 102 to deliver fluid (e.g., water) and/or air to the patient's teeth or teeth. The tip may be in the form of a scaler, end〇d〇ntic dental file, a drill, or other tool used for periodontal treatment. The 15 tip can also be made of metal or plastic, as described above. Some of these may also have the ability to transport fluids and/or air. An opening 112 is formed in the buckle 111 to receive the fluid from the handpiece 2''. The fluid can exit through the linear grooves 11 formed in the base of the tip 102. In other embodiments, the insert may have an opening 20 at its end of the tip 102 or an outer tube to enable fluid to exit the insert. Also, instead, an opening for applying a fluid to the mouth can be formed on the bobbin or the handle. For example, the transducer 108 can include a stack of thin recording plates arranged in parallel with respect to each other. Because the transducer 108 produces ultrasonic vibrations in the dental tool, the 13 transducer 108 can also be referred to as a motor. In one embodiment, the thin nickel plate may comprise 16 laminated nickel alloy strips of 90% nickel manganese (NiMn). The nickel plate can be joined together at both ends by a hard solder joint using, for example, a brazing compound comprising cadmium-free silver solder and a high temperature brazing aid. The illustrated insert 1 is a magnetostrictive insert in which a coil (e.g., coil 238, as shown in Fig. 12) in the handpiece is energized with electrical signals from the cable. Plate 1〇8 can be ultrasonically vibrated. In other embodiments, the ultrasonic dental implant can use a piezoelectric transducer as is commonly used in Europe. An ankle ring 106 is mounted on the insert 100 to engage and press against the inner surface of the handpiece 2 to form a watertight seal. For handpieces having a rotatable rotor head, the '0-ring 106 can engage the rotor head such that the ultrasonic toothed insert rotates with the rotor head. During operation, the stacking system of the thin nickel plate 108 vibrates at a frequency equal to the natural frequency of the excitation of the stack in response to the coil of the handpiece 200. After the insert is placed in the handpiece and the power supply is turned on, the operator adjusts the frequency of the power supply until the resonant frequency is reached, i.e., the natural frequency of the insert. Alternatively, the automatic adjustment unit automatically locks the gong resonance frequency once it is turned on. At this time, the accumulation body starts to vibrate. This vibration of the stack is amplified and transmitted to the tip end 02 via the connecting body portion 103. Can include any means of amplification. Ultrasonic inserts used in the United States are typically designed to vibrate at 25 kHz or 30 kHz. In response to the ultrasonic vibration of the stack of the thin nickel plate 108, the tip of the connecting body generates vibration (e.g., a quick back and forth motion of the axis of the connecting body 1〇3). In the example, the vibration in the axial direction may be between 0 00125 cm (cm) and 0.00375 cm depending on factors such as the vibration frequency, the material used for the connector 1342764 103, the length of the connecting body 1〇3, and the like. . Referring now to Figures 4 and 5, the tip has an elongated push-out portion 115 and a cylindrical dielectric portion 114 ("base"). As can be seen from Fig. 5, the push-out portion 115 has a curved shape of five. The push-out portion 115 has a circular cross section and its diameter gradually decreases from the end point ("proximal end") abutting the media face portion 114 to the other end ("distal end") of the tip end. The distal end is applied to the patient's gums/teeth during the dental procedure. As can be seen from Fig. 4, the cylindrical dielectric portion 丨 has a linear groove 11 形成 formed in the direction of the axis of the insert 1 〇. In the depicted embodiment, the flow system that travels through the illumination energy spool 126 exits via the linear trenches 110. In other embodiments, the tip may be provided with a small passageway to supply water or other fluid to the area in the mouth of the job. The tip 102 can be formed as a single integral with the connecting body 1〇3. In other embodiments, the tip portion may have a threaded portion attached to the interposer to engage a threaded opening formed in the connector portion 15 (as shown in Figure 6). With this threaded engagement, the tip can be made removable. This removability will result in the tip becoming a disposable tip that will be replaced after a single patient has been used. In other embodiments, the removable tip can also be press fit onto the connector body - corresponding to the opening. 20 Referring now to Figures 6 and 7, the connecting body 103 is also formed with a circular groove 138 near its distal end. A loop 136 is seated in the groove 138. When the illumination energy reel 126 is mounted on the connector body 103, the ankle ring 136 provides a seal between the connector body 103 and the illumination energy reel 12 6 to prevent undesirable fluid leakage. 15 1342764 The illuminating energy reel 126 can be formed as a single piece and can be slid onto the connecting body and/or the buckle 111 and rivet/pressure fit therewith. The buckle 111 has a substantially cylindrical shape and has a connecting portion 113 formed thereon, and the connecting portion 113 is fitted over a corresponding cylindrical portion of the connecting body portion 103. 5 Two openings 112 for receiving fluid from the handpiece are formed on opposite sides of the connecting portion 113. A circular groove 120 for abutting the outer 0-ring 106 has been formed on the buckle 111 adjacent to the connecting portion 113. On the distal end, the buckle 111 is formed with a pair of gripping members 132 facing each other. Each of the gripping members has an end portion that projects inwardly toward the end of the other gripping member 10. A pair of recesses 139 are formed in the connecting body portion 103 to receive the protruding end portions of the gripping members such that the gripping members 132 are riveted in the recesses 139. By this engagement, the buckle 111 of the illustrated embodiment is locked to the connecting body 103 with respect to neither the rotation nor the lateral movement. The flange 111 is also formed with circular flanges 121, 124 and a circular groove 122. A circular groove 122 is used to seat a ring 134. As can be seen from Figures 6A and 7, the illumination energy coil 99 is wound around the illumination energy reel 126, and the illumination energy reel 126 is mounted in a surrounding relationship with respect to the connector body 103. The illumination energy reel 126 can be made, for example, of a high temperature plastic such as ULTEM® or any other suitable material. The amount of voltage generated by the illuminating energy 20 coil 99 is based on factors such as the number of turns of the coil, the position of the illumination energy coil 99 with respect to the connecting body 103, the speed and frequency of the movement of the connecting body, the material used for the connecting body, and the like. It depends on similar factors. In the example, when the illumination energy coil is preferably made of 18 gauge copper wire and has a plurality of curved rings and the connecting body is preferably made of 17-4 PH stainless steel, the peak frequency can be generated by the vibration frequency of 16 1342764 25 kHz. The peak signal has a voltage signal between about 1 and about 〇 volts, preferably between about 1 and about 5 volts. Those skilled in the art will appreciate that the magnitude of the voltage produced will increase as the number of turns and/or the frequency of vibration increases. Moreover, in the illustrated embodiment, the illumination energy reel 126 (and the illumination energy coil 99) can be mounted closer to the node on the connector body 103 than the distal end attached to the tip portion 1〇2, And the voltage is increased. The node is where the longitudinal wave magnitude on the connecting body is close to zero and the longitudinal stress has a maximum value, and in the sixth drawing, the position where the grip element 132 is attached to the connecting body 1〇3 (ie, the recess) 139). 10 As can be seen from Figures 6 and 7, the illumination energy reel 126 is formed with a frame & 141 and a seat 142 on which the LED 1 〇 1 can be mounted. Also, the illumination energy reel 126 is formed with a flange 143 and a substantially cylindrical chamber 144 with an illumination energy coil 99 mounted therebetween. A convex rim 145 is formed in the generally cylindrical chamber 144. The illumination energy reel 126 also includes a ring segment 15 146 that is attached to the chamber 144. When the ultrasonic toothed insert 1 has been assembled, the ring segment 146 abuts against the flange 121 of the buckle 111. The illumination energy reel 126 is formed with a portion of the connecting portion 1〇3 which is close to the tip portion 1〇2 of the tube portion M0 away from the ring segment 146. In the depicted embodiment, the flow system enters the illumination energy reel 2 〇 126 ' via the ring segment 146 and exits the illumination energy reel 126 via the tube portion 140. The ultrasonic incisor insert of Fig. 6B is substantially identical to the ultrasonic dental implant 100 of Fig. 6A and differs in that the tip portion 1〇2 is attached with a threaded portion 109' to engage the interfacing portion 114 thereof. A threaded receiving portion ("joining portion" or "threaded tapping") 19 formed on a distal end of a connecting body portion 103. Class 17 Ultrasonic dental implants like the ultrasonic dental implant 100' Figure 6B have a light source 101 (e.g., an LED) mounted on a reel 126'. An illumination energy coil 99 is mounted on the reel 126' and electrically coupled to the light source 〇1' such that the illumination energy coil 99 converts the ultrasonic vibration energy into electrical energy used by the light source 101' for transmission "Fig. 6B The one hand grip 104' at least partially encloses the reel 126' and the illumination energy coil 99'. The replaceable tip 102 can be made of metal (such as stainless steel) or plastic (such as ULTEM®). Since the tip 1 〇 2 has a small diameter, it is easily broken if too much ultrasonic vibration is applied. On the other hand, if an insufficient ultrasonic vibration is applied, the ultrasonic tooth tool may not work effectively. Therefore, the connecting body 1G3' and the tip 1Q2' may be designed to apply an appropriate degree of vibration to the tip. Since the plastic tip is more likely to rupture than the metal tip, a shock absorbing mechanism is used on the connector σ [Π03 to reduce the impact on the plastic tip. A threaded tap 119 is formed in the connecting body portion 103, u to be screwed into the tip portion 102'. The "screw tap" will refer to a threaded opening formed on the distal end of the connecting body portion 103' in the lower 5 μ to access the monument/zero thread portion 109. The threaded portion 1〇9 engages a thread corresponding to one of the inner surfaces of the threaded tapping 119' such that the tip portion 2 is received by the connecting body portion 103'. Around the threaded screw tap 9, a groove 141 is formed, and 143' is taken to divide the pair to reduce the chance of the tip "feeling ^ sitting 0 ring 14G' and 142' ° ring to absorb the impact crack. t vibration (that is, vibration reduction), so in the case of reducing the plastic tip ear, in the connection body, only the right L street can be installed to suck A~ or two or more ankle rings for this purpose. In 1342764, the 'thread portion may have a diameter substantially the same as the diameter of the face portion, and the diameter of the threaded tap portion may be correspondingly larger to receive the thread portion. In the light emitting circuit of Fig. 8, the light source is one LEDs 51 connected in parallel with the illumination energy coil 99. Since the LED 151 emits light only in response to a voltage having a single 5 polarity, since the illumination energy coil 99 generates an alternating current (ac) voltage signal, it is only emitted in half the time. Light. However, because the LED 151 switches off and on at an ultrasonic frequency (such as 25 kHz), this fast switching of the LED is generally not perceived by the human eye' and the LED 151 will appear to be continuously turned on. In other embodiments, Light source 101 can be any He has a suitable light emitting device, such as an incandescent lamp (such as a halogen bulb). In the light emitting circuit of Fig. 9, a Zener diode 150 is connected in parallel to the LED 151. A resistor 152 Connected between the illumination energy coil 99 and the Zener diode 150, and a resistor 154 is connected between the Zener diode 150 and the LED 151. The Zener diode 150 clamps the voltage of 15 (clamp) The voltage difference seen by the LED 151 is not increased above a certain predetermined voltage. In this manner, even if the illumination energy coil 99 begins to produce a higher voltage, the brightness of the LED 151 can remain substantially uniform. For example, the Zener diode 150 The voltage can be clamped at 5 volts (V) so that the voltage seen by led 151 is no more than 5V. 20 In Figure 10, 'one LED 161 is connected in anti-parallel relationship with LED 151.
接，使其並聯式但反向連接。利用此方式，LED 151及161 係回應照明能量線圈99所產生的交流（ac)電壓而交替式接 通。因為交流(ac)電壓具有一超音波頻率（譬如25kHz)，LED 151及〗61的切換接通與關斷不可被人眼察覺，因此，LED 19 1342764 151及161兩者皆似乎呈現連續接通。其他實施例中，齊納 二極體可在第9圖中與LED 151及161各者並聯使用以對於 兩者LED钳位住電壓。 如上述，一光源可以任何方式排列，但較佳具有不佔 5體積的排列以盡量減小光源的整體尺寸。亦可使用同心陣 列的LED之排列方式，且其較佳由一微處理器所控制以使Connect them in parallel but in reverse connection. In this manner, the LEDs 151 and 161 are alternately turned on in response to the alternating current (ac) voltage generated by the illumination energy coil 99. Since the alternating current (ac) voltage has an ultrasonic frequency (for example, 25 kHz), the switching on and off of the LEDs 151 and 61 cannot be perceived by the human eye, and therefore, both of the LEDs 19 1342764 151 and 161 appear to be continuously turned on. . In other embodiments, the Zener diode can be used in parallel with each of the LEDs 151 and 161 in Figure 9 to clamp the voltage for both LEDs. As mentioned above, a light source can be arranged in any manner, but preferably has an arrangement that does not occupy 5 volumes to minimize the overall size of the light source. It is also possible to use a concentric array of LEDs, and it is preferably controlled by a microprocessor to

Figure 11 shows a side view of the handpiece 200 receiving the insert 1 as shown in Figure i. The hand piece 2 includes an integral portion 2, a rotor head and an interconnecting member 206. A rotor head 2 〇 4 positioned at a distal end of the hand piece 2 can be coupled to the remainder of the hand piece 2 。. When the insert 1 is mounted in the hand 20 of the hand 200, the ring 1〇6 is press-fitted with an inner surface of the rotor head 2〇4 such that the insert 100 together with the rotor head 2〇4 Rotate. The interconnecting member 2〇6, which is clamped at a proximal end of the handpiece 200, is coupled to a cable (such as the cable 12 of FIG. 1) to provide electrical signals and fluids (such as water) to the handpiece 2〇0. . A strain relief member 2 is formed on the interconnect member 206 to relieve strain between the connector 206 and the cable. The rotor head 204 has a generally cylindrical shape, a hollow interior, and an opening at each of the inner ends, wherein the opening is for receiving the distal end of the body 2〇2 at one end and receiving a dental insert at the other end. . For example, the rotor head 204 5 is formed with an opening 211 at its distal end to receive the ultrasonic tooth implant 1 〇〇. The rotor head 204 is formed with a plurality of recesses 21 周围 around its outer peripheral surface. Each of the recesses 210 has an oblong (or rectangular) shape and its major axis lies in a direction parallel to the central axis of the hand piece 200. The recess 21 is advantageous for a dental practitioner to hold the rotor head 204 such that it rotates relative to the body 202 (譬 10 if only one hand is used). In other embodiments, a plurality of protrusions may be formed on the rotor head 204 instead of the recesses. The body 202 is formed with a pair of grooves 203 that are substantially equidistant from the top and substantially traverse the full length of the body 202. The groove 203 is used to mount a hand grip 212 on the hand piece 200. The body 202 is also formed with a plurality of generally evenly spaced slots 208 at its bottom 15 distal to the distal end of the body 2〇2, the slots 208 being used to maintain the handle 212 in the direction of the axis of the handpiece 200. Generate movement. The body 202 is also formed with a groove 2〇5 at the bottom of its proximal end, and the groove 2〇5 is collinear with respect to the groove 208. The groove 205 cooperates with the groove 203 to engage the handle 212 to maintain the handle 212 from rotating about the central axis of the handpiece 200. Other trenches may not be used in the embodiment. The handle 212 has a joint portion 214 having a generally cylindrical shape and a hollow interior. The joint 214 slides onto the body 202 in a manner similar to the sleeve and engages the body 202 to enclose the joint with a portion of the body 2〇2. A resilient cantilever portion 218 is formed on the joint portion, and the elastic cantilever portion 218 21 1342764 is used to engage a groove 208 in the body portion 202. The engagement portion 214 is attached at its bottom surface with a grip 216 for use by a dental practitioner to hold the handpiece 200 during the dental procedure. The grip is also advantageous for use - the hand rotates the rotor #204. The grip 216 is formed on its back surface with a plurality of recesses or projections 220 for facilitating the grip of a dental practitioner. Handpiece 200 includes at least one coil mounted on a spool (shown on Figure 12) to provide energy to the stack of nickel plates such that nickel plate 1 8 vibrates at a supersonic frequency. As shown in Figure 1, the coil receives energy from the electrical energy & and fluid supply source 14 via cable 12. 10 Referring now to Fig. 12, the hand piece 200 further includes a buckle 23 which can be made of a metal such as a non-recording steel. The buckle 23 is substantially circular but does not completely form a complete circle.

For example, by applying pressure to compress the j on the buckle and the buckle 23 〇 has been aligned with the groove 231, the 230 衣 衣 230 is again placed in the circular groove 231. The coffee is locked and fixed relative to the rotor head 204. After the 4% 230 is locked to the groove 231, the rotor head and the body (10) are lightly closed by the distal end of the body 2 (10) being received in the rotor head opening. P202 is formed at its distal end with a joint 209 having a limb. The radius of the rest of the P202 is radius--the joint between the joint (10) and the rest of the body 2〇2 is located One of the substantially circular grooves 25 on the outer surface of the joint 2 - 2 1342764 (when the joint 2 〇 9 is inserted into the rotor head 204) the buckle 23 rotatably engages the groove 25 () such that the rotor head 2〇4 is rotatably coupled to the body 202. In other embodiments, the buckle 23〇 can be fixedly coupled to the body 202 and rotatably coupled to the rotor head 2〇4. The body 202 has an inner surface and It defines a hollow cavity 228 that passes through, and a reel 236 is received within the hollow cavity 228. In a typical ultrasonic tooth tool During operation, the flow system is pumped through the cable and handpiece 2 to the tip of the insert. The vibrating tip of the insert disperses the fluid stream into a spray. The spray not only keeps the tip cool but also allows the spray to cool The tooth surface remains cold 10 and provides protection against tissue damage. The fluid path through the handpiece 2 (via reel 236) is sealed to allow the fluid stream to exit the insert at a distal end via a fluid delivery path. No leakage occurs. In some embodiments, the hollow cavity 228 may have more than one compartment through which air and water may be separately delivered. In a preferred embodiment, the compartments are stacked on each other. Conveyed and water is transported through the upper compartment, so it does not become a stream of 'air/water mixture that becomes a softer mist on the teeth. The reel 236 has a generally cylindrical shape and forms a pair of circumferential grooves near its distal end. Grooves 252 and 254. The grooves 252 and 254 engage the ankle rings 232 and 234, respectively, and serve to prevent fluid from leaking out of the handpiece 200. For example, the annulus 232 20 forms a water with the inner surface of the rotor head 204. The seal is formed while the annulus 234 forms a watertight seal with the inner surface of the joint 209. A pair of generally circular flanges 256 and 258 are also formed on the spool 236. A long coil 238 is mounted between the flanges 256 and 258. On the reel 236.

Made from insulated, edged wires. In other embodiments, the coils can have substantially the same length, or longer coils can be mounted near the proximal end of the spool 236. Near the proximal end, a circular groove 272 is formed in the spool 236 for abutting a loop 242. By seating the ankle ring 242 in the groove 272, a watertight seal is formed between the spool 236 and the inner surface of the body 202 such that fluid does not leak from the handpiece 200. The spool 236 has an inner surface and defines a generally cylindrical cavity 10 for transporting fluid from the proximal end to the distal end and an opening 264 at its proximal end for receiving fluid into the cylindrical cavity. Reel 236 also forms a plurality (e.g., three) of openings 266 at its proximal end, and opening 266 is used to receive plug pins 248 in reel 236. The plug pin 248 is made of an electrically conductive material such as copper. Reel 236, body 202, rotor head 2〇4, hand grip 212, and outer casing for interconnect 15206 are made of a suitable synthetic polymeric material such as commonly referred to as "plastic," such as high temperature resin. For example, it can be fabricated using GE Plastics, such as ultM®, which is an amorphous thermoplastic polyether quinone imine. A plurality of linear grooves 268 are formed on the reel 236, a linear groove. The slots 268 20 are aligned with the respective openings 266 and extend from the openings 266 to the coils 238 and/or 240. The pins 248 respectively disposed in the openings 266 and the grooves 268 are soldered and/or otherwise electrically Connected to coils 238 and/or 240' and used to transmit electrical signals from electrical energy & fluid and/or air supply via cables through interconnects 206. 24 24 1342764 Interconnects 206 are also formed with respective engagement openings 266. A plurality of (e.g., three) elongated receptacles 246. The elongated receptacles 246 are formed, for example, on a connector portion 244 of the interconnect 206. The elongated receptacles 246 are formed for electrical generation with the plug pins 248, respectively. Electrical contact for connection. The electrical contact is located at the other end 5 electrical connection The wires in the wire are energized by, for example, supplying electrical energy to the coils 238 and 240.

The energy input device moves the input member of the generator, such as the connector body 1〇3, and the heat exchanger receives mechanical energy (10). Moving the input member may include reciprocating the input member at a frequency of from about 25 kHz to about 10. Converted to electromagnetic energy (328). To achieve this effect, a magnetized member, such as connecting body 103, moves through an electrical coil that can include at least one spirally wound electrical conductor. This movement of the magnetized member can include a magnetized structure of 15 20 pieces for a substantially sinuous axis. And/or the magnetized member about the axis of rotation = in other embodiments, the stress can be applied across the piezoelectric member by applying stress to the device as shown in Fig. 13 above. It can be used as electromagnetic energy. Other embodiments can provide illumination by using a friction illuminating material as described above with reference to Fig. 14. Using at least a part of the electromagnetic energy generated thereby, it is shown that the mechanical energy can be converted into electromagnetic When the working area can be illuminated, the first ^: uses the generator to generate - electrical energy, via the light source located at one or two = = :=- - the input - conductance = . 'Using this electric energy, it emits visible light from the light source. In the example, the thief can be configured in the tool grip. 27 1342764 • As shown in Figure 15, with this illumination, a dental procedure (332) can be performed using the tool grip. During the dental procedure, in the example, a tool is mechanically coupled to the tip of the tool grip to contact a tooth such that a surface of the tooth is disposed within the work area.
