Abstract
Description
本創作係關於一種導引套筒,尤其是一種適配於牙科手機並能限制鑽孔深度之導引套筒。 This creation is about a guide sleeve, especially a guide sleeve that is adapted to a dental handpiece and can limit the drilling depth.
隨著牙科技術之發展,越來越多病患選擇以植牙方式解決缺齒問題。植牙為一種將金屬植體(人工牙根)植入口腔齒槽骨中,替代原生牙根。等一段時間植體與骨頭緊密結合後,再安裝人工牙冠或牙橋,以恢復其美觀及咀嚼功能。 With the development of dental technology, more and more patients choose to use dental implants to solve the problem of missing teeth. Dental implant is a kind of metal implant (artificial tooth root) implanted in the alveolar bone of the oral cavity to replace the original tooth root. After a period of time when the implant is closely integrated with the bone, an artificial crown or bridge is installed to restore its aesthetics and chewing function.
植牙是一種侵入性的牙齒修復技術,在金屬植體植入口腔齒槽骨中之前,須先利用手機(handpiece)在齒槽骨上切削出適當大小的孔洞。手機上裝設適當尺寸之刀具,醫師再以手持手機方式,驅動刀具在齒槽骨上鑽孔。然而,大多狀況下鑽孔位置的兩旁還有其他牙齒,且患者開口幅度有限,限制了切削的操作空間。另一方面,在鑽孔過程中醫師必須小心地以視覺校正,避免過深、偏斜等無法回朔的不當孔洞。但大多狀況下,切削同時會產生許多切屑和血液噴濺影響視線。兩難的是,因為謹慎操作而延長的手術時間,將嚴重影響患者的安全性和舒適性。 Dental implant is an invasive tooth restoration technique. Before the metal implant is implanted in the alveolar bone of the oral cavity, a handpiece must be used to cut a hole of an appropriate size in the alveolar bone. A tool of appropriate size is installed on the mobile phone, and the doctor drives the tool to drill holes in the alveolar bone by holding the mobile phone. However, in most cases, there are other teeth on both sides of the drilling position, and the patient's opening width is limited, which limits the cutting operation space. On the other hand, during the drilling process, the physician must carefully correct visually to avoid improper holes that are too deep or skewed. But in most cases, cutting will produce a lot of chips and blood splashes at the same time, which will affect the line of sight. The dilemma is that the prolonged operation time due to careful operation will seriously affect the safety and comfort of patients.
目前,已經有先進者設計在刀具和手機之間,裝設額外的刀具中繼套。刀具中繼套之外側和內側可旋式地結合。刀具中繼套上方組合 手機,內側下方組合刀具,另有一手柄咬住刀具中繼套外側。當操作者啟動刀具且一手持住手柄時,刀具中繼套外側不旋轉,不旋轉的外側下方形成手機向下的阻礙,可限制刀具的切削深度。然而習知技藝之若干缺點在於其元件增加了相當程度的體積或高度,在有限的口腔空間中不易操作,尤其是後排臼齒位的鑽孔。然後,習知技藝之旋動件和定位件之連接處,必產生一定程度的運作磨損。甚至,習知技藝之結構複雜精密,導致產品製造成本極高。 At present, some advanced designers have designed to install additional tool relay sets between the tool and the mobile phone. The outer side and the inner side of the tool relay sleeve are rotatably combined. Upper combination of tool relay sleeve The mobile phone has a combined tool under the inner side, and another handle bites the outer side of the tool relay sleeve. When the operator starts the tool and holds the handle in one hand, the outside of the tool relay sleeve does not rotate, and the underside of the non-rotating outside forms a downward obstacle to the mobile phone, which can limit the cutting depth of the tool. However, some disadvantages of the conventional technology are that its components increase a considerable degree of volume or height, and are not easy to operate in a limited oral space, especially for drilling holes in the back molars. Then, the connection between the rotating part and the positioning part of the learned technique must have a certain degree of operational wear. Moreover, the structure of the learned technique is complex and precise, resulting in extremely high product manufacturing costs.
因此,本領域亟需一種植牙鑽孔解決方案,以解決上述問題。 Therefore, there is an urgent need for an implant drilling solution in this field to solve the above-mentioned problems.

手持機具2可以是牙科手術中常使用的手機(handpiece),用於裝設刀具3。刀具3則是可裝上手持機具2的牙科用刀具,或稱牙鑽。C型板10並不限於板型;在機頭適配結構12和C型管結構14之間,能提供相同功能之構造,皆可視為C型板10的一種。
The hand-held
機頭適配結構12之外形為自C型板10之第一側101向外延伸之圓直筒狀,內有機頭容置空間可容納並卡固機頭20。此處所述圓直筒狀是指其外型較無稜角,大致呈圓形,且兩端中至少一端有開口。機頭適配結構12內側形狀對應機頭20之結構,並在結構上可彈性的咬合機頭20。C型管結構14之外形為自C型板10之第二側102向外延伸之圓直筒狀。甚至,C
型管結構14可設計成非圓形、例如橢圓形、多角形、內凹型等,以符合齒間空隙。
The outer shape of the
本創作之機頭限位導引筒狀結構1結構精簡,製作成本低。並且,機頭限位導引筒狀結構1裝設在手持機具2後的體積,幾乎等同於手持機具2原始體積,因此機頭限位導引筒狀結構1不占用操作空間。由於本創作之機頭限位導引筒狀結構1是固設在機頭20上,而非習知技術中的裝設在機頭和刀具之間,因此不會延長刀具長度,不受到張口幅度或鑽孔位置之限制。再者,機頭限位導引筒狀結構1並不直接接觸刀具3,機頭限位導引筒狀結構1不需要有旋轉元件,不會在運作過程中磨耗。機頭限位導引筒狀結構1是利用結構卡固在機頭20上,簡單施力即可拆裝,方便快速替換。並且,機頭限位導引筒狀結構1和刀具3兩者獨立性高,替換機頭限位導引筒狀結構1不需要先拆卸刀具3;反之,替換刀具3也不需要先拆卸機頭限位導引筒狀結構1。最後,基於手持機具2上會有噴水口朝向刀具噴水,故側向開口之設計允許噴水直至鑽孔處,以順利地冷卻操作溫度以及排除血水殘屑。

於一具體實施例中,C型板10、機頭適配結構12和C型管結構14係為三個組件,彼此組裝、接合、卡固或焊合而形成機頭限位導引筒狀結構1。
In a specific embodiment, the C-shaped
於另一具體實施例中,C型板10、機頭適配結構12和C型管結構14係為一體成形之金屬結構,且係以三維金屬列印之方式增材製造而成。一體成形金屬結構可以提升機頭限位導引筒狀結構1的結構穩定性和彈韌性,有利於裝設在手持機具2之上,且在高扭力的鑽孔操作過程中不易解
體。增材製造相較減材製造更適合本創作中結構特殊且小型的機頭限位導引筒狀結構。機頭容置空間對應機頭20外型,使機頭20可拆地結合機頭適配結構12。機頭適配結構12之一端接合C型板10,另一端則可以是全開口、漸縮開口或無開口,但都能形成機頭容置空間。
In another specific embodiment, the C-shaped
請參閱圖3A至圖3D。圖3A與圖3B為根據本創作之多個具體實施例之機頭限位導引筒狀結構之透視圖。C型管結構14內有一刀具容置空間145,供刀具3穿過。C型管結構14之另一端為一刀具穿出口141,以讓刀具3經刀具內凹缺口100、刀具容置空間145和刀具穿出口141之中穿透。也就是說,在手持機具2裝設刀具3並且運作時,刀具3與C型管結構14並不直接接觸。
Please refer to Figure 3A to Figure 3D. 3A and FIG. 3B are perspective views of the barrel-shaped structure of the handpiece position limiting guide according to a number of specific embodiments of the present invention. There is a tool
如圖3A及圖3B所示,操作者可以藉由替換長度不同之C型管結構(例如C型管結構14P~14S)之機頭限位導引筒狀結構1P~1S,以決定刀具3自C型管結構14之刀具穿出口141露出之長度,進而決定鑽孔深度。圖3C和圖3D為使用圖3B之機頭限位導引筒狀結構1R和機頭限位導引筒狀結構1P鑽孔之示意圖。如圖3C和圖3D所示,機頭限位導引筒狀結構1固設在機頭20上,當裝設機頭限位導引筒狀結構1之手持機具2在一作業平面(牙床)上作業時,C型管結構14抵住作業平面而限制了機頭20向作業平面移動。相對地,機頭20所驅動的刀具3也不能再更深入鑽孔。因此,C型管結構14限制了鑽孔深度。
As shown in Figure 3A and Figure 3B, the operator can determine the
如前所述,透過選擇長度不同之C型管結構的機頭限位導引筒狀結構可決定鑽孔深度,例如,當操作者欲用刀具3在齒槽骨4鑽一較淺孔洞時,可選用具有較長之C型管結構14R的機頭限位導引筒狀結構1R裝上
手持機具2。此時刀具3自C型管結構14R所露出之部分較少,故鑽孔較淺。當操作者欲進一步用相同刀具3在齒槽骨4鑽一較深孔洞時,可選用具有較短之C型管結構14P的機頭限位導引筒狀結構1P替換裝上手持機具2。此時刀具3自C型管結構14P所露出之部分較多,故鑽孔較深。
As mentioned above, the depth of the drilling can be determined by selecting the C-tube structure with different lengths of the head limit guide cylindrical structure. For example, when the operator wants to use the
藉由本創作,操作者選定鑽孔深度後,替換相對長度之機頭限位導引筒狀結構1,確定鑽孔位置角度後即可直覺地深鑽。當到達預設鑽孔深度時,操作者可感受到手持機具2被阻擋而停止,而不需持續地、反覆地用視覺估量鑽孔深度。
With this creation, after the operator selects the drilling depth, he replaces the relative length of the head limit guide
由於刀具3之刀柄30通常直徑較小,刀具內凹缺口100之孔徑長可以較窄,讓C型板10之第一側101有更大的面積卡固機頭20。由於刀具3之刀尖31通常直徑較大,且要避免C型管結構14接觸刀尖31而磨損,刀具容置空間145和刀具穿出口141之徑長需要較寬,以避免鑽孔時殘屑堆積在刀具容置空間145內。
Since the
此外,機頭適配結構120之頂端或側面可以有一突出卡榫127,卡住機頭20避免機頭限位導引筒狀結構1滑脫。

請一併參閱圖1A、圖1B、圖1C、圖4A及圖4B。圖4A及圖4B為根據圖1A之機頭限位導引筒狀結構之弧形角度示意圖。如圖4A及圖4B所示,C型板10有一虛擬垂直軸線Y落在C型板10之中心軸。C型管結構14和機頭適配結構12各自平行於虛擬垂直軸線Y而沿伸。C型板10有一中心通孔105,中心通孔105連通內凹缺口100,虛擬垂直軸線Y穿越中心通孔105。機頭適配結構12之橫切面形成一第一弧形。第一弧形之兩端以虛擬垂直軸線Y為圓心沿伸而形成一第一角度A1之夾角,第一角度A1介於160度至210
度之間。反過來說,第一側向開口120以虛擬垂直軸線Y為圓心的第一開口角度介於150度至200度之間。第一側向開口120的開口大小有利於結合並卡固機頭20,也便於將機頭20拆卸自機頭適配結構12中拆卸。

C型管結構14之橫切面形成一第二弧形,第二弧形之兩端以虛擬垂直軸線Y為圓心沿伸而形成一第二角度A2之夾角,第二角度A2至少為220度,最大為340度。反過來說,第二側向開口140以虛擬垂直軸線Y為圓心的第二開口角度介於20度至140度之間。當手持機具2和機頭限位導引筒狀結構1以圖2的方式接合時,第二側向開口140的第二開口角度讓刀具可以通過進入到C型管結構14之內,手持機具噴水孔的水柱也可以沖到鑽孔位置。

請參閱圖2和圖6。圖6為根據本創作之一具體實施例之植牙
導引限位工具組之示意圖。於本具體實施例中,植牙導引限位工具組應用於配合手持機具2使用。植牙導引限位工具組包含有複數個機頭限位導引筒狀結構1和一植牙導引套5。手持機具2和機頭限位導引筒狀結構1手段功效與先前實施例大致相同,於此不再贅述。手持機具2、刀具3和單一機頭限位導引筒狀結構1預先組合,且植牙導引套5預先固設在手術部位上,而結合的手持機具2和單一機頭限位導引筒狀結構1可在植牙導引套5中軸向滑動。植牙導引套5進一步具有頂部開口50、第三側向開口(圖未示)、第一軸向導引孔51和第二軸向導引孔52。頂部開口50位於植牙導引套5之一端。第三側向開口自頂部開口50向植牙導引套5之另一端延伸。

第一軸向導引孔51之內壁配合機頭限位導引筒狀結構1之機頭適配結構12之外型,以利機頭限位導引筒狀結構1在第一軸向導引孔51內軸向移動。
The inner wall of the first
植牙導引套5進一步包含有一齒模固定元件55,使植牙導引套5固定在牙齒上。植牙導引套5底部有一導引套刀具穿孔54。機頭限位導引筒狀結構1之外徑長略小於於第一軸向導引孔51內徑長,因此機頭限位導引筒狀結構1可以在第一軸向導引孔51內上下滑動。是以刀具3可以從導引套刀具穿孔54中穿出,進行齒槽骨切削。
The
實際應用時,操作者持手持機具,將機頭連同機頭限位導引筒狀結構1從頂部開口50進入第一軸向導引孔51,並向下深入到第二軸向導引孔52。而第三側向開口便是用於讓連通機頭20的手持機具臂22通過。然而,為了讓手持機具臂22通過,第三側向開口需要一定的展開角度。第三側向開口的展開角度會使機頭20連同機頭限位導引筒狀結構1容易向第三
側向開口外側傾斜晃動,進而使刀具3偏離了原本的鑽孔軸線。
In actual application, the operator holds the hand-held machine tool, and inserts the handpiece together with the handpiece limit guide
為防止機頭20連同機頭限位導引筒狀結構1向第三側向開口外側傾斜,本創作進一步設計了孔徑較窄,包覆角度較大的第二軸向導引孔52。第二軸向導引孔52配合機頭限位導引筒狀結構1之C型管結構14,且第二軸向導引孔52之孔徑長小於第一軸向導引孔51之孔徑長。此時,第一軸向導引孔51和第二軸向導引孔52連通的內壁有著凹凸的兩次轉折。第一軸向導引孔51和第二軸向導引孔52,可以兩階段地引導機頭限位導引筒狀結構1軸向移動。第二軸向導引孔52容納C型管結構14,而C型管結構14深入第二軸向導引孔52時,第二軸向導引孔52包覆C型管結構14的角度大於第一軸向導引孔51包覆機頭適配結構12的角度。是以,藉由第二軸向導引孔52包覆C型管結構14,機頭20和刀具3更不容易傾斜晃動,能夠穩定鑽孔軸線。
In order to prevent the
綜上所述,本創作之機頭限位導引筒狀結構最主要有利於操作者在鑽孔時切削深度的掌握。本創作之機頭限位導引筒狀結構精簡,製造成本低;體積小,不需要額外操作空間;運作時機頭限位導引筒狀結構不與刀具直接接觸,沒有運作磨損之問題。並且可方便地替換不同規格之機頭限位導引筒狀結構,縮短手術時間。利用本創作之植牙導引套可限制機頭限位導引筒狀結構徑向移動或傾斜,而使手持機具可以穩定的軸向移動。 To sum up, the barrel-shaped structure of the head limit guide of this creation is most beneficial to the operator's grasp of the cutting depth when drilling. The barrel-shaped structure of the head limit guide of this invention is simplified, and the manufacturing cost is low; the volume is small, and no additional operating space is required; the barrel-shaped structure of the head limit guide does not directly contact the tool during operation, and there is no problem of operation wear. And can easily replace different specifications of the handpiece limit guide tube structure, shorten the operation time. Using the implant guide sleeve of this invention can limit the radial movement or tilt of the handpiece limiting guide cylindrical structure, so that the handheld device can move stably in the axial direction.
