M353727 八、新型說明： 【新型所屬之技術領域】 本創作是關於自體骨切取儀的改良。 【先前技術】 現今，使用自體骨來做骨移植的手術日益普遍。雖然人 造骨或合成骨也常被使用，但是自體骨移植術在骨移植方面 仍是最佳的方法。M353727 VIII. New description: [New technical field] This creation is about the improvement of autologous bone cutting instrument. [Prior Art] Today, surgery using autologous bone for bone grafting is becoming more common. Although human bone or synthetic bone is often used, autologous bone grafting is still the best method for bone grafting.
為了自體骨移植首先要切取自體骨。取自體骨的一般方 法有：使用鑿子狀的儀器從骨組織表面刮出骨的方法，或者 用馬達驅動的鑿狀儀器或超音波儀器來切取塊狀骨，再用粉 碎機粉碎的方法等。 但是這些自體骨切取方法消耗的時間較長，在骨切取中 會發生細贼染，切取出的自體骨有局部消失 【新型内容】 因此本創作的目的在於提供：一種在自體骨切取時最小 化局«失#’最大限度防止細_染’從—個自 儀取出多種形態的骨的自體骨切取儀。 本創作的另一種目的是提供：能切取符 並且最大限度縮短自體骨切取與移植丰 ▼的月， 取儀。植手術時間的自體骨切 為了實現上述目的，本創作於驅動器（ )的前端部分（12)連接帶有鑛齒的觀管 = (22)下端與前端有幾個粉碎刀片〇2)的、⑽運接處 形成可分離的螺絲型連接處，構成自體骨切=碎口（30) M353727 如上所述，本創作在自體骨切取時最小化其消失量’ 农大限度防止細菌感染，並且單用一個切取儀就可以取出 多樣的骨’切取符合移植使用用途的骨，來最大限度縮短 自體骨切取與移植手術時間。 【實施方式】 為讓本創作之上述及其他目的、特徵及優點能更明顯易 懂’下文特舉本創作之較佳實施例，並配合所附圖式，作詳 細說明如下： 第1圖是自體骨切取儀的斜視圖，第2圖是第1圖的分 解斜視圖，第3圖是第1圖的分解截面圖。 本創作是使儀器使用者用一個自體骨切取儀就可以切取 塊狀骨或粉狀骨為目的。 本發明如第1圖和第2圖所示’有前端連接處（12)的 手柄’有鋸齒（24)的鑽孔管（30)和有多個刀片（32)的 粉碎口（30)來組成，上述手柄（1〇)與驅動器（如第5 及7圖的40)連接並且能驅動旋轉。 與驅動器（40)連接旋轉的手柄（1〇)的另一端有圓筒 型前端連接處（12)。手柄（1〇)的前端連接處（12)是— 個有凸緣的圓筒，橡膠圈與凸緣結合在圓筒前端形成—雙旋 轉圈’在與鑽孔管（20)結合時能與鑽孔管（2〇)的—雙 接槽穩固連接。 而且手柄（10)的前端連接處（12)的圓筒底部形成 絲口（ 18) ’能與帶有刀片（32)的粉碎口（3〇)下端的、 絲（34)穩固連接，儀器使用者在必要時分離粉碎口。 M353727 口（30)前端的粉碎刀片如第2圖所示 來構成，所有的刀片以中央的尖頭頂點（32art的刀片 )勻二方向展開。各刀片最好在不接觸鑽孔 )内部的靶圍内充分展開。 (2〇 粉碎刀片㈤尖頭頂點（32a)與粉碎 管（則連接到手柄（1〇)的前端連接處 )鐵= (20)前端稍微突出。這樣的粉碎口（3〇)麵頂T孔官 )的突出設計是為了固定骨切取儀（2) 時= 尖頭頂點⑶姆刀取部分的支=碎： 止骨切取儀（2)的滑動。 直防 底部帶有鋪（24)的鑽孔f⑽在其 的‘丁，型插槽⑶，第5圖與第7圖的驅動器（4 = 轉方向處形成約20。向下傾斜的插槽，使其插槽與前 處⑽喊轉器㈤峡。為了錄鬆鑽進骨組織内， 在鑽孔管（20)的底部形成纖（24)，在其表面形成鑽石 塗層或鋼碳化物塗層，使此鋸齒比其他部分具有相對較高的 硬度。 ° 鑽孔管（20)上形成多個孔（28)，在其外部形成一到2 個的彎曲的切開孔槽（26)，此切開孔槽的下半部形成更深 的插槽。鑽孔管（20)侧面的孔（28)和切開孔槽（26)在 自體骨切取手術中使冷水更好的滲進手術部位。 而且鑽孔管（20)的表面形成一個從底端的鋸齒（2〇) 延伸到上部的格尺，使儀器使用者能更好的判斷鑽孔管（20 )鑽進的深度。 M353727 第4圖是已装置鑽孔管（20)與粉碎口（30)的自體骨 切取儀的戴面圖’第5圖是如第4圖所示裝置好的本儀器從 牙槽骨切取自體骨的狀態截面圖。第6圖是粉碎口（30)卸 除後的本儀器的戴面圖，第7圖是使用如第6圖所示的本儀 器切取自體骨的狀態戴面圖。 本創作的使用方法中，如第4圖和第5圖所示，結合使 用鑽孔官（20)和粉碎口（ 3〇)，就可以取出粉狀的自體骨 ’如第6圖和第7圖所示，卸除粉碎口（30)單用鑽孔管（ 20)就可以取出塊狀的自體骨。 上述結構的本創作自體骨切取儀，比現有的切取方法更 具如下優點。它能最小化自體骨切取時其消失量，最大限度 防止細菌感染。 雖然本創作已利用上述較佳實施例揭示，然其並非用以 限定本創作，任何熟習此技藝者在不脫離本創作之精神和範 圍之内，相對上述實施例進行各種更動與修改仍屬本創作所 保護之技術範疇，因此本創作之保護範圍當視後附之申往 利範圍所界定者為準。 M353727 【圖式簡單說明】 第1圖：自體骨切取儀的斜視圖。 第2圖：第1圖的分解斜視圖。 第3圖：第1圖的分解截面圖。 第4圖：裝置完鑽孔管和粉碎口的自體骨切取儀的截面 圖。 第5圖：使用裝置完鑽孔管和粉碎口的自體骨切取儀來 切取骨的狀態截面圖。 ^ 第6圖：卸除粉碎口的自體骨切取儀的截面圖。 第7圖：單用鑽孔管切取骨的狀態截面圖。 【主要元件符號說明】 2 自體骨切取儀 10 手柄 12 別端連接處 14 旋轉器 18 螺絲口 20 鑽孔管 22 插槽 24 鋸齒 26 切開孔槽 28 孔 30 粉碎口 32 粉碎刀片 32a 尖頭頂點 34 螺絲 40 驅動器For autologous bone grafting, the autologous bone is first cut. The general methods of taking bones include: using a chisel-like instrument to scrape bone from the surface of bone tissue, or using a motor-driven chisel or ultrasonic instrument to cut the block bone, and then crushing with a pulverizer. . However, these autologous bone cutting methods take a long time, and fine thief dyeing occurs in the bone cutting, and the autologous bone removed is partially disappeared. [New content] Therefore, the purpose of this creation is to provide: a kind of cutting in the autogenous bone. When the minimization of the bureau «missing #' to the maximum extent to prevent fine-staining's self-extracting bones from a variety of forms of bone. Another purpose of this creation is to provide: the ability to cut the symbol and minimize the month of autologous bone cutting and transplantation. Autologous bone cutting of the implantation time In order to achieve the above purpose, the front end portion (12) of the actuator ( ) is connected to the tube with the ore tooth = (22) the lower end and the front end have several crushing blades 〇 2) (10) Separate screw-type joints formed at the joint to form autologous bone cut = broken mouth (30) M353727 As described above, this creation minimizes the amount of disappearance when autologous bone is cut. 'Nongda limits prevent bacterial infection, and With a single cutter, you can remove a variety of bones' cut bones for use in transplantation, to minimize the time for autologous bone harvesting and transplantation. [Embodiment] The above and other objects, features and advantages of the present invention will become more apparent. The following detailed description of the preferred embodiments of the present invention, together with the accompanying drawings, FIG. 2 is an exploded perspective view of the first embodiment, and FIG. 3 is an exploded cross-sectional view of the first embodiment. This creation is intended to allow the instrument user to cut a piece of bone or powdery bone with an autologous bone cutting instrument. The present invention, as shown in Figures 1 and 2, has a drilled tube (30) having a serration (24) and a pulverizing port (30) having a plurality of blades (32). In composition, the handle (1〇) is coupled to a driver (such as 40 of FIGS. 5 and 7) and is capable of driving rotation. The other end of the handle (1〇) that is coupled to the drive (40) has a cylindrical front end connection (12). The front end connection (12) of the handle (1〇) is a flanged cylinder, and the rubber ring and the flange are combined at the front end of the cylinder. The double rotating ring can be combined with the drilling tube (20). The double-groove of the drill pipe (2〇) is firmly connected. Moreover, the bottom of the cylinder at the front end connection portion (12) of the handle (10) forms a wire opening (18)' which can be firmly connected with the wire (34) at the lower end of the pulverizing port (3〇) with the blade (32), and is used by the instrument. The separator is separated when necessary. The smashing blade at the front end of the M353727 port (30) is constructed as shown in Fig. 2, and all the blades are unfolded in the center direction with the center pointed apex (32art blade). Preferably, each of the blades is fully deployed within the target perimeter that does not contact the borehole. (2 〇 smashing blade (5) pointed apex (32a) and pulverizing tube (then connected to the front end of the handle (1 〇)) iron = (20) the front end is slightly protruding. Such smashing port (3 〇) top T hole The official design is to fix the bone cutting device (2) = the tip of the pointed tip (3) the branch of the knife is removed = the broken: the sliding of the bone cutting device (2). Straight against the bottom of the hole with the paving (24) f (10) in its 'D, type slot (3), the driver of Figure 5 and Figure 7 (4 = about 20 in the direction of the turn. Slot down the slot, Make the slot and the front (10) shouting (5) gorge. In order to record the loosening into the bone tissue, a fiber (24) is formed at the bottom of the drilling tube (20), and a diamond coating or a steel carbide coating is formed on the surface thereof. The layer has a relatively high hardness compared to the other parts. ° A plurality of holes (28) are formed in the bore tube (20), and one or two curved slit holes (26) are formed on the outside thereof. The lower half of the incision slot forms a deeper slot. The hole (28) and the incision slot (26) on the side of the bore tube (20) allow for better penetration of cold water into the surgical site during autologous bone cutting operations. The surface of the bore tube (20) forms a ruler extending from the bottom serration (2〇) to the upper section, allowing the instrument user to better determine the depth of the borehole (20). M353727 Figure 4 The wearing surface of the autogenous bone cutting instrument that has been equipped with the drilling tube (20) and the pulverizing port (30) is shown in Fig. 4. A sectional view of the state of the autologous bone is taken. Fig. 6 is a front view of the apparatus after the smashing port (30) is removed, and Fig. 7 is a section of the apparatus for cutting the autogenous bone using the apparatus as shown in Fig. 6. State wear mask. In the use of this creation, as shown in Fig. 4 and Fig. 5, combined with the driller (20) and the crushing port (3〇), the powdered autologous bone can be taken out. As shown in Fig. 6 and Fig. 7, the removal of the pulverizing port (30) can be used to remove the block-shaped autologous bone. The above-mentioned structure of the original autologous bone cutting instrument is more than the existing cutting. The method has the following advantages: it can minimize the amount of disappearance of the autologous bone when it is cut, and prevent bacterial infection to the utmost. Although the present invention has been disclosed by the above preferred embodiments, it is not intended to limit the creation, and any skill in the art is familiar. Without departing from the spirit and scope of the present invention, various changes and modifications to the above embodiments are still within the technical scope protected by this creation. Therefore, the scope of protection of this creation is defined by the scope of the application.
