Abstract
本創作提出一種植體,其具有一外表面及複數個空腔。外表面形成有複數個開口,而空腔分別連通於該等開口。空腔的最大橫向截面的面積大於該等開口的截面積,該橫向截面平行於該外表面。因此,本創作的優點在於,植體的外表面形成有許多連通於空腔的開口,因此在植體外表面上塗敷藥劑時,藥劑可流入空腔內。由於空腔的最大橫向截面大於開口,因此藥劑可流入空腔後不易由開口流出,而能吸附更多的藥劑。
Description
本創作是關於一種植入人體的植體,特別是該植體的表面結構。
許多手術都會將人工製造物植入人體,這些人工製造物即為俗稱的植體。常見的植體是植牙手術的人工牙根,或是心導管手術的血管支架。人工牙根植體是穿入牙床,因此牙床的骨頭是會預先鑽出一個小洞來讓人工牙根***並固定。一段時間後牙床的骨頭會增生,因此能使人工牙根穩固地被固定在牙床上。然而,骨頭增生的速度非常緩慢,因此患者在術後有諸多不便。如何提升骨頭增生的速度,便成為植牙手術的一大課題。相反地,血管支架植體手術後,若血管增生,則血管容易再次堵塞,因此如何降低再阻塞率,也是血管支架手術的一大課題。
本創作的主要目的在於,提出一種植體,其能吸附更多的藥劑,藉此幫助人體受植體植入的部分復元,或能視情況促進或減緩組織增生。
為達上述目的,本創作所提出的植體具有:一外表面,該外表面形成有複數個開口;以及複數個空腔,其分別連通於該等開口,該等空腔的最大橫向截面的面積大於該等開口的截面積,該最大橫向截面平行於該外表面。
因此,本創作的優點在於,植體的表面形成有許多連通於空腔的開口,因此在植體表面上塗敷藥劑時,藥劑可流入空腔內。由於空腔的最大橫向截面大於開口,因此藥劑可流入空腔後不易由開口流出,而能吸附更多的藥劑。
如前所述之植體更具有複數個通道,其一端分別連通於該等開口,另一端分別連通於該等空腔。
如前所述之植體中,該等空腔的縱向截面為圓形、橢圓形、鵝卵形、或三角形,該縱向截面垂直於該外表面。
如前所述之植體中,該等空腔的橫向截面越遠離該外表面而越大,該橫向截面平行於該外表面。
如前所述之植體為人工牙根或血管支架。

首先請參考圖1及圖2。本創作提出一種植體。於本創作的第一實施例中,植體為植牙手術用的人工牙根A。本創作的植體具有一外表面10及複數個空腔12,且可選擇性地更具有複數個通道13。
外表面10形成有複數個開口11,而空腔12分別連通於該等開口11。本實施例中,空腔12是透過通道13連通於開口11。具體而言,通道13的一端連通於一開口11,另一端連通於一空腔12。本實施例中,一個開口11連通於一個通道13,以及連通於一個空腔12;但於其他實施例中,也可以多個開口11連通於一個空腔12。於圖2中,空腔12的排列為示意圖,其顯示了開口11及空腔12呈規則排列而分佈於外表面10上;但於其他實施例中開口11及空腔12也可不規則排列,如圖3所示,於本實施例中的另一個態樣中,可不具有通道,而是一空腔12直接連通於開口11。
各個空腔12的縱向截面可為圓形、橢圓形、鵝卵形、或三角形,而該縱向截面垂直於外表面10。各個空腔12的橫向截面沿著與外表面的距離而有所變化,且橫向截面的最大面積大於所連通的開口11的截面積,而橫向截面平行於外表面10。藉此,使空腔12內有更多空間能吸附藥劑。其中,各空腔12的表面可為平整面,或可具有不規則的凹凸結構。
如圖4及圖5所示的態樣中,空腔12的橫向截面越遠離該外表面10而越大。換言之,於此態樣中空腔12的縱向截面可呈現三角形。
接著請參考圖6及圖7。於本創作的第二實施例中,植體為心導管手術的血管支架B。血管支架B大抵呈管狀,因此其外表面10包含了外環面及內環面。本實施例中,於外環面及內環面皆形成有開口11及空腔12,但於其他實施例中,可僅於外環面上形成有開口11及空腔12。
透過上述結構,植體的表面形成有許多連通於空腔12的開口11,因此在植體表面上塗敷藥劑時,藥劑可流入空腔12內。由於空腔12的最大
橫向截面大於開口11,因此藥劑可流入空腔12後不易由開口11流出,而能吸附更多的藥劑。若植體為人工牙根A,則藥劑包含了能幫助牙床骨頭增生的成份,因此本創作的植體能吸附更多藥劑幫助骨頭增生,能縮短人工牙根A固定於牙床上的時間。另一方面,若植體為血管支架B,則藥劑包含了防止血管增生的成份,因此本創作的植體能吸附更多藥劑降低血管增生的情況,達到降低手術後血管的再阻塞率。
