眼用具有閥之穿刺套管 優先權主張
本申請案主張在2009年12月23日提出的美國暫時性專利申請案序號61/289,449，標題"眼用具有閥的穿刺套管"之優先權的利益，其發明家為喬色路易絲羅佩茲(Jose Luis Lopez)，阿尼爾K.佩特奈拉(Anil K. Patnala)及米迦勒M.馬丁(Michael M. Martin)，其全文藉此以參考方式併入本文，如全然完全及完整地於本文中提出般。
發明領域
本發明廣泛涉及眼科手術。更特別的是，但非為限制，本發明涉及眼用穿刺套管及排出器。
 發明背景
可由外科醫生使用顯微手術工具從在人體中需小心處理及有限的空間移除組織，例如，在眼睛上手術(諸如用來移除玻璃體、血液、瘢痕組織或晶狀體的程序)。此工具可包括一控制操縱臺及一外科醫生使用來解剖及移除組織之外科手持件。關於後房手術，該手持件可為玻璃刀具探針、雷射探針或用來切割或破碎組織之超音波破碎機(fragmenter)，及可藉由長的空氣壓力(氣流式)線及/或電纜、光纜或用來將輸液供應至手術地點及用來從該地點抽回或吸出流體及被切割/破碎的組織之撓性管連接至該控制操縱臺。手持件的切割、輸液及吸出功能可由遠端控制操縱臺來控制，其中該操縱臺不僅提供該外科手持件(例如，往復運動或旋轉切刀或超音波振動針)電力，而且亦可控制輸液的流動及提供用來吸出流體及被切割/破碎的組織之真空(相對於環境)來源。操縱臺的功能可由外科醫生手動地控制(例如，透過使用腳操作的開關或比例控制)。
在後房手術期間，外科醫生可在程序期間使用數個手持件或工具。此程序會需要這些工具插入及移出切口。此重覆移出及插入可造成眼睛在切口位置處損傷。為了解決此關心的事，至少在1980年代中期發展出襯套式套管(hubbed cannulae)。這些裝置可包括一附加有襯套的窄管。可將該管插入在眼睛中的切口至最多該襯套處，其中該襯套可作用為制子以防止管子完全進入眼睛中。該襯套可被縫至眼睛以防止不慎移除。可經由該管將手術工具插入眼睛中，及該管可保護切口側壁不由該工具重覆接觸。此外，外科醫生可使用該工具(藉由操縱該工具，當該工具經由該管插入眼睛中時)來幫助在手術期間定位眼睛。先述技藝套管的缺點可包括在眼睛表面上凸出的高度，和缺乏任何在工具交換或移除期間控制眼壓喪失的設備。當手術裝置不存在時，眼睛(其為一有壓力的眼球)會將水或玻璃體排出該開放式套管。在先述技藝套管中，藉由將一栓塞或罩套塞入管中來密封該套管及防止流體與組織釋出來防止眼壓喪失。此可為一耗時過程，其會需要額外的測試設備和其它操作室人員的輔助及會增加手術後感染的風險。
 發明概要
在多個具體實例中，穿刺套管可被構形成用來插入眼睛中，以使得在手術期間容易插入及移出工具。該套管可附上頂蓋(其附加以抑制頂蓋相對於套管轉動)。該頂蓋可包括一密封物，其用來抑制當該套管插入眼睛中時流體流出套管(當未插入工具時)。在某些具體實例中，該密封物可模塑進該頂蓋中；或可包括一固定在套管與頂蓋間之薄片，使得該密封物不會相對於套管及頂蓋轉動。在某些具體實例中，該套管及頂蓋可經由凸出片/槽界面以固定性方式一起迅速咬合，使得該套管及頂蓋無法沒有損害該套管或頂蓋的至少部分而分離。在某些具體實例中，可在該密封物的隙縫中滑動地接收一排出用套管，以允許流體經由該套管從眼睛排出。在某些具體實例中，該套管可包括至少一個凹痕，以便當該排出器被插入套管中時摩擦地接合該排出器的一部分。

要瞭解前述一般說明及下列詳細說明二者僅為範例及解釋，且想要如所主張般提供本發明的進一步解釋。
 較佳實施例之詳細說明
第1圖闡明穿刺套管101及頂蓋103的具體實例。穿刺套管101可被構形成用來插入眼睛中，以使得在手術期間容易插入及移出工具。套管101可包括能延伸進入眼睛(例如，通過鞏膜、結膜等等)中的井幹(shaft)105。在某些具體實例中，套管101可接附至頂蓋103。例如，套管101可在套管101上包含一或多個凸出片107，其被構形成接合相應的槽109(例如，闡明在第1圖中的套管101包括四個凸出片107以接合四個在頂蓋103上的相應槽109)。亦考慮到其它接附。例如，該套管101可包括槽及該頂蓋可包括凸出片。在某些具體實例中，套管101可透過黏著劑、熱黏合等等接附至頂蓋103。在某些具體實例中，密封物111可耦合至頂蓋103(例如，可將密封物111至少部分配置在井幹105與頂蓋109間)以形成一超模壓(overmolded)閥。如顯示在第1圖中，密封物111的表面可曝露在頂蓋109上。在某些具體實例中，密封物111之曝露的表面可包括一或多個隙縫113以允許手術工具通過進入套管101中。在缺乏手術工具時，密封物111可抑制流體流過密封物111。
第2圖闡明附上頂蓋103的套管101之具體實例(例如，在凸出片107接合於各別的槽109中後)。在某些具體實例中，該凸出片/槽界面可防止頂蓋103相對於套管101轉動(例如，在套管101插入眼睛期間)。在某些具體實例中，凸出片107可被構形成讓頂蓋103固定性抓住套管101(如此頂蓋103無法沒有破壞套管101及/或頂蓋103之部分從套管101移除)。例如，凸出片107(及套管101)可由不銹鋼製得及頂蓋103可由塑膠(例如，聚碳酸酯)製得。亦考慮到其它材料。在頂蓋103與套管101間固定性抓住可防止在手術(例如，玻璃體視網膜手術)期間從套管101不慎地移除頂蓋103。
第3a圖闡明於頂蓋103上在密封物111中的隙縫113之具體實例的上俯視圖。第3b圖闡明具有數個實施例尺寸(以英吋提供)的套管101及頂蓋103之具體實例的側視圖。亦考慮到其它尺寸。例如，儘管套管101的外徑顯示出如為0.029英吋(與23標準規格套管相應)，在另一個具體實例中，該套管的外徑可為0.0243英吋(對25標準規格套管來說)。亦考慮到其它外徑。
第4a-c圖闡明頂蓋103及密封物111的具體實例之截面。密封物111可由彈性體(例如，聚矽氧)製得。在某些具體實例中，密封物111可接附至頂蓋103以抑制密封物111相對於頂蓋103轉動。例如，密封物111可超模壓進在頂蓋103中的凹洞403及一或多個孔洞401中。在某些具體實例中，密封物111可包括矽薄片405，其與頂蓋103分開形成及在將頂蓋103組合到套管101上期間插入頂蓋103與套管101間。在此情況中，密封物111可透過摩擦力安裝而接附至頂蓋103及套管101。亦考慮到其它接附(例如，黏著劑)。
第5a圖闡明套管101在穿刺插件501上的具體實例。在某些具體實例中，該穿刺插件501可包括接附至柄505的穿刺刀片503。在某些具體實例中，柄505可由塑膠製得及刀片503可由不銹鋼製得。亦考慮到其它材料。穿刺刀片503可延伸通過井幹105末端及可包括一或多個尖銳的邊緣，以用於套管101之插入刺穿眼睛1401(例如，刺穿一通過鞏膜1403及進入玻璃體1405中的孔洞)。在某些具體實例中，導板507可裝入導板槽115中，以抑制在套管101插入眼睛1401期間頂蓋103/套管101相對於柄505轉動。在某些具體實例中，導板507可能鬆開地接合導板槽115，使得當將穿刺插件501從頂蓋103/套管101抽出時，導板507不會將頂蓋103/套管101拉出眼睛1401。例如，導板507可以摩擦力(其小於當套管101在眼睛中時由眼睛在套管101的外邊上所發揮的摩擦力)摩擦地接合導板槽115。
雖然所描出的導板507為可收入導板槽115中的凸出片，亦考慮到其它連結外觀。例如，導板507及導板槽115可包括不同連結外觀(諸如環及棒)或可包括其它連結構件(例如，連結磁鐵(在柄及頂蓋103每個上各一個)、接合o-環(在柄及頂蓋103每個上各一個)等等)。在某些具體實例中，導板507/導板槽115交互作用可防止在套管101與頂蓋103間轉動，以便穿刺柄505繞著該柄的軸之任何有角度的移動可傳送至頂蓋103然後至套管101。此交互作用可提供玻璃體視網膜外科醫生在套管101插入鞏膜1403期間相對於穿刺柄505有角度地控制套管101。第5b圖闡明套管101在含有運送蓋511(其可咬在套管101上及/或在穿刺插件501上以保護套管101及/或穿刺插件501)的穿刺插件501上之具體實例。
第6a-b圖闡明排出器601的具體實例。當例如手術工具封閉套管時，儘管該具有閥的穿刺套管之密封物111可隔離套管不讓流體流進或出套管，排出用套管603可被構形成能滑入密封物111的隙縫113中，以允許流體經由套管101從眼睛排出(例如，參見第7圖)。在某些具體實例中，排出器601在開放位置中可抓住密封物111，以允許流體(例如，氣體或液體)經由套管101排出。例如，在以另一種流體置換氣體的程序期間，氣體(或另一種流體)可流過套管101及從排出器601出去。排出器601可進一步包括框邊609，以提供用以防止排出器一路滑入密封物111中的制子。排出用套管603可具有一小於穿刺套管101的內徑之外徑，以允許排出用套管603滑過密封物111及進入穿刺套管101中。排出用套管603可進一步包括具有至少一定尺寸的框邊609，其中該尺寸足夠大以防止排出器601完全滑入穿刺套管101中，例如，框邊609的直徑可比穿刺套管101的內徑大。
在某些具體實例中，排出器601可為一與套管分離的裝置，以允許排出器601插入及移出而沒有加入或移除套管101的零件(例如，不必需移除套管101的頂蓋103)。排出器601之尺寸亦可允許使用者(例如，外科醫生)在排出器601之插入及移出期間以手指(或例如，鑷子)處理排出器601。
在某些具體實例中，排出器601可包括一撓性管605(例如，聚矽氧管)，其摩擦接合排出用套管603。管605可提供一排出過程的視覺指示器(例如，至少部分透明)，例如，若物質從眼睛中溢流出時(諸如在黏的流體控制注入程序期間的聚矽氧)，聚矽氧可流入管605中及可由使用者看見。在某些具體實例中，管605可使用作為從套管101中移出排出器時的握緊表面(例如，輔助由手指或鑷子緊握)。排出用套管603可包括管部分607，其被構形成沿著管607(其可由例如不銹鋼製得)的外周圍接收撓性管605。在某些具體實例中，管607及排出用套管603可一體形成。第6b圖闡明根據具體實例之數個實施例尺寸(以英吋提供)。亦考慮到其它尺寸。在某些具體實例中，排出器601的尺寸可允許工具通過排出器601，當排出器601在密封物111中時。
第8圖闡明排出器601在套管101中的具體實例之截面。在某些具體實例中，套管101可包括至少一個凹口801，當排出器601插入套管101中時摩擦地接合排出用套管603的部分。凹口801可按規格尺寸切割，以提供排出器601足夠的阻力，以在程序期間適當地保持排出器601。在某些具體實例中，當從套管101抽回排出器601時，在凹口801與排出器601間之阻力可少於將套管101拉出眼睛所需要者(如此當將排出器601拉出套管101時，套管101不會被拉出眼睛，同時套管101在眼睛中)。
亦考慮到其它排出器的具體實例。例如，排出器901的具體實例顯示在第9a-b圖中。如在第9a-b圖中看見，排出器901可不包括管605，而是可取代為單一件。排出器901可經深抽成型及可包括一用來與在套管101上的滯留外觀配對的滯留外觀。亦考慮到其它形成技術(例如，排出器901可經模塑)。在某些具體實例中，該排出器可不包括滯留外觀。在第10a-c圖中顯示出更另一個具體實例，如為排出器1001。排出器1001可包括一大鐘形注入口，當將排出器1001插入套管101中時，可較容易經由排出器1001插入及移出工具。排出器1001亦可包括一或多個滯留外觀1003，以便當將排出器1001插入套管101中時增加在排出器1001與套管101間之夾住性。
第11圖闡明一根據具體實例用來形成具有閥的穿刺套管之方法的流程圖。在流程圖中所提供的要素僅具闡明性。多種所提供的要素可省略，可加入額外要素，及/或可以與下列所提供不同的順序進行多種要素。
在1101中，可形成頂蓋103。例如，頂蓋103可經模塑，以包括用來接收聚矽氧密封物111的通孔401。用於頂蓋103之模塑方法可包括注塑成型法、壓縮成型法、吹噴成型法、迴轉成型法等等。亦考慮到其它用來形成頂蓋103的技術(例如，鑄塑)。
在1103中，可將密封物111超模壓到頂蓋103上。例如，密封物111可包括一已模塑進入頂蓋103之凹洞403中的彈性體(諸如聚矽氧)，及可流入孔洞401中以將密封物111弄牢至頂蓋103。在某些具體實例中，可將頂蓋103放入一限定出通過頂蓋103用於密封物111的空間之模具中。然後，可將彈性體注入模具中及流過所限定的空間通過頂蓋103，以在頂蓋103中形成密封物111。亦考慮到其它製造方法。例如，密封物111及頂蓋103可經模塑如為一體(例如，在單一模具中使用相同材料用於頂蓋103及密封物111二者)。在某些具體實例中，密封物111可與頂蓋103分別地形成(例如，參見第10圖)。在某些具體實例中，該密封物可形成含有隙縫113，或可在密封物形成後於密封物111中形成隙縫113(例如，可使用尖銳的邊緣切入密封物111中形成隙縫113)。
在1105中，可形成套管101。例如，套管101可經深抽成型。深抽成型該套管101可包括從一材料的碟狀物開始，在一或多組公/母沖模間加壓其以深抽出該套管101。在套管形成中的最後步驟可包括移除過多材料及/或拋光套管101。在某些具體實例中，可剪掉在公及母沖模間於凸出片107間之材料，或可以其它方法移除(例如，切掉)其。在某些具體實例中，套管101可經模塑(例如，注塑成型法、壓縮成型法、吹噴成型法、迴轉成型法、擠壓成型法等等)。亦考慮到其它用於套管形成的技術。在某些具體實例中，套管101可由不銹鋼或塑膠製得。亦可使用其它材料。在某些具體實例中，套管101可形成含有咬合式凸出片107。例如，用於套管101的沖模或模具可包括用來形成凸出片的空間，或該凸出片可透過機器成形在套管101上形成。亦考慮到其它凸出片形成技術。
在1107中，可將頂蓋103附加至套管101。例如，可讓凸出片107與相應槽109咬合。在某些具體實例中，頂蓋103可稍微變形以接收凸出片107，或凸出片107可被構形成當將頂蓋103加壓到套管101上時可稍微變形，然後當頂蓋103之相應槽109通過在凸出片107上時返回其起始狀態。凸出片107可足夠堅硬(例如，由不銹鋼製得)，如此可無法沒有破壞套管101及/或頂蓋103的部分從套管101中移除頂蓋103。
第12圖闡明一根據另一個具體實例用來形成具有閥的穿刺套管之方法的流程圖。在流程圖中所提供的要素僅具有闡明性。多種所提供的要素可省略，可加入額外要素，及/或可以與在下列所提供不同的順序進行多種要素。
在1201中，可形成(例如，經由模塑)頂蓋1103。在某些具體實例中，頂蓋1103可形成含有接收槽109。
在1203中，可形成密封物111(諸如，聚矽氧薄片405)。在某些具體實例中，聚矽氧薄片405可經模塑具有隙縫113，或可在模塑後於聚矽氧薄片405中形成隙縫113(例如，可使用尖銳的邊緣切割聚矽氧薄片形成隙縫113)。
在1205中，可形成套管101。例如，套管101可以不銹鋼模塑及可包括凸出片107。
在1207中，可將聚矽氧薄片405塞入套管101與頂蓋103之間，及頂蓋103可附加至套管101(例如，頂蓋103可咬合到套管101上，使得槽109可接收凸出片107)。
第13圖闡明一根據具體實例使用該具有閥的穿刺套管之排出器的方法之流程圖。在流程圖中所提供的要素僅有闡明性。多種所提供的要素可省略，可加入額外要素，及/或可以與在下列所提供不同的順序進行多種要素。
在1301中，穿刺刀片503可插入通過在密封物111中的隙縫113及通過套管101。在1303中，可以穿刺刀片503刺穿眼睛1401及可將套管101推入眼睛中。在1305中，如需要時，可在插入期間轉動穿刺刀片503及套管101。在1307中，可將穿刺刀片503抽出離開在眼睛1401中的套管101。在1309中，如需要，可插入排出器601以打開密封物111，以允許流體/氣體經由套管101排出及出去眼睛1401。排出器601可被移除及/或如需要再插入密封物111及套管101中，在此程序期間沒有從眼睛中抽回套管101。可使用例如使用者的手指或鑷子對來進行排出器601的插入抽回。
可由普通熟知技藝之人士對所顯現的具體實例製得多種改質。將由熟習該項技術者從本專利說明書之考慮及本發明揭示於本文的實施明瞭本發明之其它具體實例。想要本專利說明書及實施例僅視為範例，且本發明的真實範圍及精神由下列申請專利範圍及其同等物指示出。
