According to the following description and the scope of patent application, the advantages and features of the present invention will be more clear. It should be noted that the drawings all adopt very simplified forms and all use imprecise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
第一圖係本發明具內視功能之低溫大氣電漿裝置一實施例之配置示意圖。如圖中所示,此具內視功能之低溫大氣電漿裝置10包括一脈衝產生器12、一氣體源14、一流量控制器13、一電漿產生器16以及一可撓式延伸單元18。
The first figure is a schematic configuration diagram of an embodiment of the low-temperature atmospheric plasma apparatus with internal viewing function of the present invention. As shown in the figure, the low-temperature
脈衝產生器12係用以產生一高壓脈衝。提供至電漿產生器16以產生大氣電漿。在一實施例中,此脈衝產生器12係一直流脈衝產生器、一交流脈衝產生器或是一射頻脈衝產生器。就此高壓脈衝之波型來看,此高壓脈衝可以是一方波脈衝或是一弦波脈衝。
The
氣體源14係用以提供一工作氣體至電漿產生器16。此工作氣體可以是氮氣,可以是一惰性氣體,如氦氣或氬氣,亦可以是一混合氣體,如氦氣與氬氣之
混合、氦氣與氧氣之混合、或是氦氣與氮氣之混合等。
The
流量控制器13係設置於氣體源14與電漿產生器16之間,以控制氣體源14提供至電漿產生器16之氣體流量。
The
電漿產生器16包括一管體161、一第一電極162、一第二電極164、一氣體入口166與一電漿出口168。其中,第一電極162係延伸至管體161內,第二電極164係設置於管體161外側且與第一電極162間隔一預設距離。第一電極162與第二電極164係電性連接脈衝產生器12以接收高壓脈衝。
The
在一實施例中,管體161係由絕緣材質(如玻璃、石英等)構成。第一電極162係一鎢電極。此鎢電極係延伸至管體161內,且電性連接至一高電壓輸出端HV。第二電極164係一銅環電極。此銅環電極係環設於管體161外側且電性連接至一接地端G。脈衝產生器12係透過高電壓輸出端HV與接地端G產生高壓脈衝。藉此,脈衝產生器12所產生之高壓脈衝即可施加於管體161內。更精確地說,就是施加於管體161內對應於第一電極162與第二電極164間之空間,以產生大氣電漿。
In one embodiment, the
氣體入口166與電漿出口168係設置於管體161上。氣體入口166係透過流量控制器13連通至氣體源14以取得工作氣體。在一實施例中,氣體入口166與電漿出口168係位於管體161之相對兩端部。來自氣體源14之工作氣體係經由氣體入口166進入管體161內部,搭配脈衝產生器12所產生之高壓脈衝,以產生大氣電漿由電
漿出口168向外噴射。
The
前述電漿產生器16之配置,尤其是第一電極162與第二電極164之配置位置僅為本案之一示例。任何具有電漿出口168可將大氣電漿向外噴射之電漿產生器16均可適用於本案發明。
The configuration of the
可撓式延伸單元18包括一電漿延伸管182、一內視訊號線184與一排氣管186。
The
電漿延伸管182包括一連接端1822與相對於連接端1822之一電漿噴射端1824。電漿延伸管182之連接端1822係連接電漿出口168。來自電漿出口168之大氣電漿係透過電漿延伸管182之引導由電漿噴射端1824噴出。進一步來說,電漿產生器16內產生之大氣電漿會隨同其內部氣流,由電漿出口168流動至電漿延伸管182,並由電漿噴射端1824噴出。在一實施例中。此電漿延伸管182係一具有優異絕緣效果的矽膠軟管,以確保電漿可順利由電漿噴射端1824噴出。
The
內視訊號線184包括一近端1842與一遠端1844。近端1842係用以耦接至一內視鏡外接螢幕20。遠端1844係併排於電漿噴射端1824之側邊,以利於即時檢視身體內部進行大氣電漿處理之組織表面。
The internal
排氣管186包括一前端1862與一尾端1864。尾端1864係用以連接至一氣體幫浦30。前端1862係併排於電漿噴射端1824之側邊,以排除電漿噴射端1824噴出之氣體。
The
如圖中所示,在本實施例中,內視訊號線
184與排氣管186係併排於電漿延伸管182之側邊集結成束,以利於延伸進入身體內部。
As shown in the figure, in this embodiment, the internal video signal line
The 184 and the
第二圖係本發明可撓式延伸單元內部配置之一實施例之剖面示意圖。相較於第一圖之實施例中,內視訊號線184與排氣管186係併排於電漿延伸管182之側邊集結成束,本實施例之可撓式延伸單元28包括一中心部28a與一外圍部28b,電漿延伸管282係位於中心部28a,內視訊號線284係位於外圍部28b,排氣管286則是位於電漿延伸管282與內視訊號線284之間。也就是說,電漿延伸管282、排氣管286與內視訊號線284係構成一同心圓結構。此配置方式有助於縮減可撓式延伸單元28之截面寬度,以利於延伸至身體內部。
The second figure is a schematic cross-sectional view of an embodiment of the internal configuration of the flexible extension unit of the present invention. Compared with the embodiment in the first figure, the internal
第三圖係本發明可撓式延伸單元內部配置之另一實施例之剖面示意圖。相較於第二圖之實施例,本實施例之可撓式延伸單元38亦包括一中心部38a與一外圍部38b,電漿延伸管382係位於中心部38a,內視訊號線384係位於外圍部38b。不過,本實施例之排氣管386則是併排於內視訊號線384之外側。在一實施例中,此排氣管386係呈現圓管結構。
The third figure is a schematic cross-sectional view of another embodiment of the internal configuration of the flexible extension unit of the present invention. Compared with the embodiment in the second figure, the
第四圖係本發明可撓式延伸單元內部配置之又一實施例之剖面示意圖。相較於第二圖與第三圖之實施例中,均呈現有同心圓結構,本實施例之可撓式延伸單元48之電漿延伸管482、內視訊號線484與排氣管486均呈現圓管結構,且倆倆緊靠成束。此配置方式可降低製造成本。
The fourth figure is a schematic cross-sectional view of another embodiment of the internal configuration of the flexible extension unit of the present invention. Compared with the embodiments in the second and third figures, they all show concentric structures. The
相較於傳統技術,本發明之具內視功能之低溫大氣電漿裝置10,具有可撓式延伸單元18,28,38,48可對身體內部之組織表面進行電漿處理,並可讓使用者即時檢視患部狀態進行調整,以利於電漿處理之進行。
