請參照第1A~1E圖,第1A圖繪示依照本發明一實施例之植入器械100的外觀示意圖,第1B圖繪示第1A圖之植入器械100的分解圖,第1C圖繪示第1A圖之植入器械100沿方向1C-1C’的剖面圖,第1D圖繪示第1A圖之植入器械100沿方向1D-1D’的剖面圖,而第1E圖繪示第1A圖之植入器械100沿方向1E-1E’的剖面圖。 1A to 1E, FIG. 1A is a schematic view showing the appearance of the implant device 100 according to an embodiment of the present invention, and FIG. 1B is an exploded view of the implant device 100 of FIG. 1A, and FIG. 1C is a view 1A is a cross-sectional view of the implant device 100 along the direction 1C-1C', FIG. 1D is a cross-sectional view of the implant device 100 of FIG. 1A along the direction 1D-1D', and FIG. 1E is a 1A diagram A cross-sectional view of implant device 100 in direction 1E-1E'.
植入器械100用以將膜片置入生物組織,其中的膜片例如是角膜、組織修護膜片等,而生物組織例如是人體或動物的組織,如眼球組織或體內器官組織等。 The implant device 100 is used to place a membrane into a biological tissue, wherein the membrane is, for example, a cornea, a tissue repair membrane, or the like, and the biological tissue is, for example, a tissue of a human or an animal, such as an eyeball tissue or an internal organ tissue.
植入器械100包括套筒110、膜片儲存元件120、注入元件130、氣泡產生元件140及止逆閥150。膜片儲存元件120固定於套筒110。注入元件130穿設於套筒110及膜片儲存元件120,且包括擷取端131及連接端132。擷取端131用以擷取膜片且所述擷取端131具有第一開孔131a。氣泡產生元件140連接於連接端132,且用以提供氣體從第一開孔131a輸出。藉由注入元件130的轉動,擷取端131可平移地伸出膜片儲存元件120外或縮進膜片儲存元件120內。 The implant device 100 includes a sleeve 110, a diaphragm storage element 120, an injection element 130, a bubble generating element 140, and a check valve 150. The diaphragm storage element 120 is secured to the sleeve 110. The injection component 130 is disposed through the sleeve 110 and the diaphragm storage component 120 and includes a capture end 131 and a connection end 132. The capturing end 131 is used to capture the diaphragm and the capturing end 131 has a first opening 131a. The bubble generating member 140 is coupled to the connection end 132 and is configured to supply gas from the first opening 131a. By the rotation of the injection element 130, the extraction end 131 is translatable out of the membrane storage element 120 or retracted into the membrane storage element 120.
進一步來說,在將膜片置入生物組織前,可轉動注入元件130讓擷取端131可平移地伸出膜片儲存元件120外,以擷取膜片。在擷取膜片後,可轉動注入元件130讓擷取端131平移地縮進膜片儲存元件120內,以將膜片存放於膜片儲存元件120內,進而保護膜片,避免植入器械100在後續進入生物組織過程中, 使膜片受到損傷。在植入器械100***生物組織後,氣泡產生元件140可產生氣體,此氣體從第一開孔131a輸出,以將膜片推出至生物組織。在本實施例中,氣泡產生元件140可以是氣囊,其可由彈性材料製成,如橡膠。如此,只要壓縮氣泡產生元件140,即可將氣泡產生元件140內的氣體(如空氣)擠壓到注入通道134a內。在另一實施例中,氣泡產生元件140可以是幫浦或其它任何適合的產氣元件或吹氣元件。 Further, prior to placing the membrane into the biological tissue, the injection element 130 can be rotated to allow the extraction end 131 to extend out of the membrane storage element 120 to capture the membrane. After the diaphragm is captured, the injecting member 130 can be rotated to retract the capturing end 131 into the diaphragm storage element 120 to store the diaphragm in the diaphragm storage element 120, thereby protecting the diaphragm and avoiding implanting the device. 100 in the subsequent process of entering biological tissue, The diaphragm is damaged. After the implant device 100 is inserted into the biological tissue, the bubble generating member 140 can generate a gas that is output from the first opening 131a to push the diaphragm out to the biological tissue. In the present embodiment, the bubble generating member 140 may be an air bag which may be made of an elastic material such as rubber. Thus, as long as the bubble generating member 140 is compressed, the gas (e.g., air) in the bubble generating member 140 can be squeezed into the injection passage 134a. In another embodiment, the bubble generating element 140 can be a pump or any other suitable gas generating element or blowing element.
如第1A圖所示,第一開孔131a的數量例如是一個,然亦可超過一個。以幾何形狀來說,開孔131a例如是一多邊形孔,如矩形孔,然亦可為圓孔、橢圓孔、長條孔或其它幾何形狀。然只要能讓氣體順利推出膜片即可,本發明實施例不限定第一開孔131a的數量、幾何形狀及/或開口面積。 As shown in FIG. 1A, the number of the first openings 131a is, for example, one, but may be more than one. In terms of geometry, the opening 131a is, for example, a polygonal hole, such as a rectangular hole, but may also be a circular hole, an elliptical hole, a long hole or other geometric shape. However, the embodiment of the present invention does not limit the number, geometry, and/or opening area of the first openings 131a as long as the gas can be smoothly pushed out of the diaphragm.
如第1C圖所示,擷取端131包括端壁1311及第一周緣壁1312。第一開孔131a係貫穿第一周緣壁1312。換言之,本發明實施例之第一開孔131a係開設於第一周緣壁1312,而非端壁1311。進一步來說,膜片通常只掛設在第一周緣壁1312上,而由於第一開孔131a係開設於第一周緣壁1312,因此氣泡產生元件140所產生的氣體從第一開孔131a輸出時得以推出掛設在第一周緣壁1312上的膜片。此外,端壁1311可不具有任何貫孔結構,如此可讓氣泡產生元件140所產生的氣體大部分從第一開孔131a輸出,以獲得最大氣體輸出效率,使膜片與植入器械分離。 As shown in FIG. 1C, the extraction end 131 includes an end wall 1311 and a first peripheral wall 1312. The first opening 131a extends through the first peripheral wall 1312. In other words, the first opening 131a of the embodiment of the present invention is formed on the first peripheral wall 1312 instead of the end wall 1311. Further, the diaphragm is usually only hung on the first peripheral wall 1312, and since the first opening 131a is opened in the first peripheral wall 1312, the gas generated by the bubble generating element 140 is from the first opening. At the output of 131a, the diaphragm attached to the first peripheral wall 1312 is pushed out. In addition, the end wall 1311 may not have any through-hole structure, so that most of the gas generated by the bubble generating element 140 is output from the first opening 131a to obtain maximum gas output efficiency, separating the diaphragm from the implanted instrument.
如第1C及1E圖所示,膜片儲存元件120具有儲存通道120a,注入元件130的擷取端131的外徑D3小於儲存通道120a的內徑D4。如此,膜片可存放於儲存通道120a與擷取端131之間的儲存空間SP1(虛線所界定的範圍)內,以受到保護。 As shown in FIGS. 1C and 1E, the diaphragm storage element 120 has a storage passage 120a, and the outer diameter D3 of the extraction end 131 of the injection element 130 is smaller than the inner diameter D4 of the storage passage 120a. Thus, the diaphragm can be stored in the storage space SP1 (the range defined by the broken line) between the storage passage 120a and the extraction end 131 to be protected.
如第1C圖所示,注入元件130具有注入通道134a。注入通道134a從連接端132往擷取端131方向延伸,且與第一開孔131a連通,如此使在注入通道134a內的傳輸氣體可透過第一開孔131a輸出。此外,注入通道134a從連接端132露出一第一開口132a,使氣泡產生元件140所產生的氣體得以透過第一開口132a進入注入通道134a內。 As shown in FIG. 1C, the injection element 130 has an injection channel 134a. The injection channel 134a extends from the connection end 132 toward the extraction end 131 and communicates with the first opening 131a such that the transport gas in the injection channel 134a can be output through the first opening 131a. In addition, the injection channel 134a exposes a first opening 132a from the connection end 132, so that the gas generated by the bubble generating element 140 can pass through the first opening 132a into the injection channel 134a.
如第1C圖所示,注入元件130包括轉動部133及管體134。管體134具有前述擷取端131、連接端132及注入通道134a。如圖所示,管體134例如是直管,其中擷取端131與連接端132為直管的相對二端。管體134及膜片儲存元件120例如是由透明材料製成,可方便觀察膜片10的狀態。例如,由於管體134及膜片儲存元件120係透明,因此即使膜片10位於膜片儲存元件120內部,也能觀察到膜片10的狀態,如膜片10的位置及/或捲曲狀態等。在一實施例中,膜片10可具有顏色,可讓操作者透過顏色更容易觀察膜片10的狀態。在一實施例中,管體134及膜片儲存元件120例如是由塑膠製成。 As shown in FIG. 1C, the injection element 130 includes a rotating portion 133 and a tube body 134. The tube body 134 has the aforementioned extraction end 131, the connection end 132, and the injection channel 134a. As shown, the tubular body 134 is, for example, a straight tube, wherein the capturing end 131 and the connecting end 132 are opposite ends of the straight tube. The tube body 134 and the diaphragm storage member 120 are made of, for example, a transparent material, and the state of the diaphragm 10 can be easily observed. For example, since the tube body 134 and the diaphragm storage element 120 are transparent, even if the diaphragm 10 is located inside the diaphragm storage element 120, the state of the diaphragm 10, such as the position and/or the curl state of the diaphragm 10, can be observed. . In one embodiment, the diaphragm 10 can have a color that allows the operator to more easily observe the condition of the diaphragm 10 through the color. In one embodiment, the tubular body 134 and the diaphragm storage element 120 are, for example, made of plastic.
管體134之注入通道134a只透過第一開孔131a及第一開口132a與外界連通。如此,可使氣泡產生元件140所產 生的氣體大部分或甚至全部氣體從第一開口132a進入,且大部分或甚至全部氣體從第一開孔131a輸出,以獲得最大的氣體輸出效率。 The injection passage 134a of the pipe body 134 communicates with the outside only through the first opening 131a and the first opening 132a. Thus, the bubble generating element 140 can be produced. Most or even all of the gas of the raw gas enters from the first opening 132a, and most or even all of the gas is output from the first opening 131a to obtain maximum gas output efficiency.
如第1C圖所示,注入元件130包括第二凸緣136,第二凸緣136從管體134的連接端132的第二周緣壁1321突出。氣泡產生元件140緊密地包覆第二凸緣136,以密封氣泡產生元件140與第二凸緣136之間的縫隙。如此,氣泡產生元件140所產生的氣體從氣泡產生元件140與第二凸緣136之間的縫隙洩漏的量最少,甚至沒有洩漏量,以獲得最大的氣體輸出效率。在一實施例中,第二凸緣136與管體134可以是一體成形的結構,然,本發明實施例不以此為限。 As shown in FIG. 1C, the injection element 130 includes a second flange 136 that projects from the second peripheral wall 1321 of the connection end 132 of the tubular body 134. The bubble generating member 140 tightly covers the second flange 136 to seal the gap between the bubble generating member 140 and the second flange 136. As such, the gas generated by the bubble generating member 140 leaks from the gap between the bubble generating member 140 and the second flange 136 with the least amount, even without leakage, to obtain maximum gas output efficiency. In an embodiment, the second flange 136 and the tubular body 134 may be integrally formed. However, the embodiment of the present invention is not limited thereto.
此外,轉動部133以相對套筒110可轉動且可平移的方式連接於套筒110。進一步來說,如第1C圖所示,套筒110具有內螺紋111,轉動部133具有一與內螺紋111螺合的外螺紋135。如此,藉由螺紋運動,轉動部133與套筒110可相對轉動且同時相對平移。 Further, the rotating portion 133 is coupled to the sleeve 110 in a rotatable and translatable manner relative to the sleeve 110. Further, as shown in FIG. 1C, the sleeve 110 has an internal thread 111, and the rotating portion 133 has an external thread 135 that is screwed to the internal thread 111. Thus, by the thread movement, the rotating portion 133 and the sleeve 110 are relatively rotatable and simultaneously relatively translated.
此外,管體134以相對轉動部133可轉動但不可平移的方式連接於轉動部133。如此,當轉動部133相對套筒110轉動時,管體134可相對轉動部133轉動,且管體134受到轉動部133的帶動而隨轉動部133一起平移。 Further, the tubular body 134 is coupled to the rotating portion 133 in a rotatable but non-translatable manner with respect to the rotating portion 133. As such, when the rotating portion 133 is rotated relative to the sleeve 110, the tubular body 134 is rotatable relative to the rotating portion 133, and the tubular body 134 is driven by the rotating portion 133 to be translated together with the rotating portion 133.
進一步來說,如第1C圖所示,轉動部133具有相對之第一止擋壁133s1與第二止擋壁133s2,注入元件130具有第 一凸緣137,第一凸緣137配置於管體134上,且位於第一止擋壁133s1與第二止擋壁133s2之間,以拘束管體134與轉動部133的相對平移運動。換言之,第一凸緣137受限於第一止擋壁133s1與第二止擋壁133s2之間,因此當轉動部133平移時,可帶動管體134同步平移。在一實施例中,第一凸緣137與管體134可以是一體成形的結構,然,本發明實施例不以此為限。如圖所示,雖然第一凸緣137與第一止擋壁133s1之間具有餘隙,但此餘隙不影響第一凸緣137受限於第一止擋壁133s1與第二止擋壁133s2之間。在另一實施例中,第一凸緣137與第一止擋壁133s1之間的餘隙可以減少,或甚至沒有餘隙,即第一凸緣137固定在第一止擋壁133s1與第二止擋壁133s2之間。 Further, as shown in FIG. 1C, the rotating portion 133 has a first stop wall 133s1 and a second stop wall 133s2, and the injection element 130 has a first A flange 137 is disposed on the tube body 134 and located between the first stop wall 133s1 and the second stop wall 133s2 to restrain the relative translational movement of the tube body 134 and the rotating portion 133. In other words, the first flange 137 is limited between the first stop wall 133s1 and the second stop wall 133s2, so that when the rotating portion 133 is translated, the tubular body 134 can be driven to synchronously translate. In an embodiment, the first flange 137 and the tubular body 134 may be integrally formed. However, the embodiment of the present invention is not limited thereto. As shown, although there is a clearance between the first flange 137 and the first stop wall 133s1, the clearance does not affect the first flange 137 from being limited by the first stop wall 133s1 and the second stop wall. Between 133s2. In another embodiment, the clearance between the first flange 137 and the first stop wall 133s1 may be reduced, or even without clearance, that is, the first flange 137 is fixed to the first stop wall 133s1 and the second Between the stop walls 133s2.
如第1D圖所示,管體134具有第一外徑D11及第二外徑D12,第一外徑D11大於第二外徑D12。膜片儲存元件120具有第一內徑D21與第二內徑D22,第一內徑D21大於第二內徑D22。第一外徑D11與第一內徑D21配合,而第二外徑D12與第二內徑D22配合。藉由大小徑配合,可拘束管體134與膜片儲存元件120的相對轉動運動。換言之,當轉動部133轉動時,即使管體134與轉動部133具有相對轉動的自由度,但由於受限膜片儲存元件120的大小徑拘束,管體134無法相對轉動部133轉動,而只能相對膜片儲存元件120進行平移運動。如此,在手術中,第一開孔131a的方位不會因為轉動部133的轉動而改變。 As shown in FIG. 1D, the tubular body 134 has a first outer diameter D11 and a second outer diameter D12, and the first outer diameter D11 is larger than the second outer diameter D12. The diaphragm storage element 120 has a first inner diameter D21 and a second inner diameter D22, and the first inner diameter D21 is greater than the second inner diameter D22. The first outer diameter D11 cooperates with the first inner diameter D21, and the second outer diameter D12 cooperates with the second inner diameter D22. The relative rotational movement of the tubular body 134 and the diaphragm storage element 120 can be constrained by the size and diameter fit. In other words, when the rotating portion 133 is rotated, even if the tubular body 134 and the rotating portion 133 have a degree of relative rotational rotation, the tubular body 134 cannot rotate relative to the rotating portion 133 due to the restriction of the size of the restricted diaphragm storing member 120, and only The translational movement can be performed relative to the diaphragm storage element 120. As such, the orientation of the first opening 131a does not change due to the rotation of the rotating portion 133 during the operation.
如第1D圖所示,管體134具有相對之第一平面 134s1與第二平面134s2,第二外徑D12為第一平面134s1與第二平面134s2之間的距離。第一平面134s1與第二平面134s2例如是一圓柱的相對二切面。在另一實施例中,管體134具有一橢圓剖面,其中橢圓剖面的長軸長度例如是第一外徑D11,而橢圓剖面的短軸長度例如是第二外徑D12。然只要管體134具有相異的二外徑,且膜片儲存元件120具有相配合的二相異內徑即可,本發明實施例不限定管體134及膜片儲存元件120的幾何結構。 As shown in FIG. 1D, the tubular body 134 has a first plane opposite thereto. 134s1 and the second plane 134s2, the second outer diameter D12 is the distance between the first plane 134s1 and the second plane 134s2. The first plane 134s1 and the second plane 134s2 are, for example, opposite cylindrical faces of a cylinder. In another embodiment, the tubular body 134 has an elliptical cross section, wherein the major axis length of the elliptical cross section is, for example, the first outer diameter D11, and the minor axis length of the elliptical cross section is, for example, the second outer diameter D12. However, the embodiment of the present invention does not limit the geometry of the tube body 134 and the diaphragm storage element 120 as long as the tube body 134 has two different outer diameters and the diaphragm storage element 120 has a matching two-phase inner diameter.
此外,如第1C圖所示,止逆閥150可配置在第一開口132a。例如,止逆閥150可以是矽膠塞,其部分塞入第一開口132a內。止逆閥150可防止回壓回水,例如,止逆閥150允許氣體G1進入注入通道134a,但不允許生物組織的組織液流出注入通道134a。以氣泡產生元件140為氣囊舉例來說,當壓縮氣泡產生元件140時,氣泡產生元件140內形成高壓而將氣泡產生元件140內的氣體透過止逆閥150推入注入通道134a內;當釋放氣泡產生元件140時,氣泡產生元件140內的壓力回復。由於止逆閥150的配置,可避免在壓力回復時將生物組織內的組織液吸入注入通道134a或透過止逆閥150流出注入通道134a外。如此一來,在下次壓縮氣泡產生元件140時,可避免注入通道134a內或流出至注入通道134a外的組織液被回送至生物組織內,進而避免汙染生物組織。此外,若無汙染問題或汙染程度在容許範圍,植入器械100也可省略止逆閥150。 Further, as shown in FIG. 1C, the check valve 150 may be disposed in the first opening 132a. For example, the check valve 150 can be a silicone plug that is partially inserted into the first opening 132a. The check valve 150 prevents back pressure from returning to the water. For example, the check valve 150 allows the gas G1 to enter the injection passage 134a, but does not allow the tissue fluid of the biological tissue to flow out of the injection passage 134a. Taking the bubble generating member 140 as a balloon, for example, when the bubble generating member 140 is compressed, a high pressure is formed in the bubble generating member 140 to push the gas in the bubble generating member 140 through the check valve 150 into the injection passage 134a; when the bubble is released When the element 140 is produced, the pressure within the bubble generating element 140 is restored. Due to the configuration of the check valve 150, it is possible to prevent the tissue fluid in the biological tissue from being sucked into the injection channel 134a or out of the injection channel 134a through the check valve 150 when the pressure is restored. In this way, when the bubble generating element 140 is compressed next time, the tissue fluid in the injection channel 134a or flowing out of the injection channel 134a can be prevented from being returned to the biological tissue, thereby avoiding contamination of the biological tissue. In addition, the implant device 100 can also omit the check valve 150 if there is no contamination problem or the degree of contamination is within the allowable range.
在一實施例中,止逆閥150具有第二開孔150a,開 孔150a位於注入通道134a內。第二開孔150a的內徑D5小於第一開口132a的內徑D6。在一實施例中,第二開孔150a的內徑D5可大致等於或小於5毫米,以提供前述防止回壓回水的技術效果。 In an embodiment, the check valve 150 has a second opening 150a that opens The aperture 150a is located within the injection channel 134a. The inner diameter D5 of the second opening 150a is smaller than the inner diameter D6 of the first opening 132a. In an embodiment, the inner diameter D5 of the second opening 150a may be substantially equal to or less than 5 mm to provide the aforementioned technical effect of preventing back pressure back.
此外,如第1C圖所示,氣泡產生元件140具有第二開口140a1(繪示於第1B圖)及第三開孔140a2。氣泡產生元件140以第二開口140a1裝配於管體134。第三開孔140a2提供類似止逆閥150的技術效果,於此不再贅述。此外,第三開孔140a2例如是圓孔、橢圓孔或其它幾何型態的孔。然只要能提供前述防止回壓回水的技術效果,本發明實施例不限定第三開孔140a2的數量、幾何形狀及/或開設位置等。 Further, as shown in FIG. 1C, the bubble generating element 140 has a second opening 140a1 (shown in FIG. 1B) and a third opening 140a2. The bubble generating member 140 is fitted to the tubular body 134 with the second opening 140a1. The third opening 140a2 provides a technical effect similar to the check valve 150, and will not be described herein. Further, the third opening 140a2 is, for example, a circular hole, an elliptical hole or a hole of another geometric shape. However, as long as the technical effect of preventing the back pressure backwater can be provided, the embodiment of the present invention does not limit the number, geometry, and/or opening position of the third opening 140a2.
當氣泡產生元件140與管體134分離時,氣泡產生元件140的內部只透過第二開口140a1及第三開孔140a2與外界相通。當氣泡產生元件140裝配於管體134時,由於第二開口140a1幾乎或完全密封,氣泡產生元件140的內部只透過第三開孔140a2與外界相通。如此一來,當壓縮氣泡產生元件140時,氣泡產生元件140的內部可產生足夠高壓去推動氣泡產生元件140內的氣體。此外,在一實施例中,第三開孔140a2的內徑D7可介於約0.5毫米~約1.5毫米之間,例如是約1毫米。在另一實施例中,若無需求,氣泡產生元件140也可省略第三開孔140a2,即,當氣泡產生元件140與管體134分離時,氣泡產生元件140的內部只透過第二開口140a1與外界相通。 When the bubble generating member 140 is separated from the tube body 134, the inside of the bubble generating member 140 communicates with the outside only through the second opening 140a1 and the third opening 140a2. When the bubble generating member 140 is fitted to the tube body 134, since the second opening 140a1 is almost or completely sealed, the inside of the bubble generating member 140 communicates with the outside only through the third opening 140a2. As such, when the bubble generating element 140 is compressed, the interior of the bubble generating element 140 can generate a sufficiently high pressure to push the gas within the bubble generating element 140. Moreover, in an embodiment, the inner diameter D7 of the third opening 140a2 may be between about 0.5 mm and about 1.5 mm, such as about 1 mm. In another embodiment, the bubble generating element 140 may also omit the third opening 140a2 if not required, that is, when the bubble generating element 140 is separated from the tube 134, the inside of the bubble generating element 140 only passes through the second opening 140a1. Connect with the outside world.
請參照第2及3圖,第2圖繪示第1C圖之植入器械100的擷取端131伸出膜片儲存元件120的示意圖,而第3圖繪示第1C圖之植入器械100的擷取端131縮進膜片儲存元件120內的示意圖。 Please refer to FIGS. 2 and 3 . FIG. 2 is a schematic diagram showing the capturing end 131 of the implant device 100 of FIG. 1C protruding from the diaphragm storage component 120, and FIG. 3 is a view showing the implanting device 100 of FIG. 1C. A schematic view of the capture end 131 retracted into the diaphragm storage element 120.
如第2圖所示,轉動部133繞第一轉動方向S11轉動,以帶動管體134往伸出方向S12平移,進而使擷取端131的第一開孔131a伸出膜片儲存元件120外,以便擷取膜片。如圖所示,注入元件130的轉動部133具有一位於套筒110外的第一外端面133s3,套筒110具有第二外端面110s1,第一外端面133s3與第二外端面110s1係相面對,第一外端面133s3與第二外端面110s1決定注入元件130相對套筒110的一第一極限位置,如第2圖所示的位置。 As shown in FIG. 2, the rotating portion 133 is rotated about the first rotating direction S11 to drive the tubular body 134 to translate in the extending direction S12, so that the first opening 131a of the capturing end 131 extends beyond the diaphragm storage element 120. In order to capture the diaphragm. As shown, the rotating portion 133 of the injecting member 130 has a first outer end surface 133s3 outside the sleeve 110, the sleeve 110 has a second outer end surface 110s1, and the first outer end surface 133s3 is opposite to the second outer end surface 110s1. The first outer end surface 133s3 and the second outer end surface 110s1 determine a first extreme position of the injection element 130 relative to the sleeve 110, as shown in FIG.
詳言之,當轉動部133相對套筒110繞第一轉動方向S11轉動時,透過螺紋運動,轉動部133同時相對套筒110沿伸出方向S12平移,直到第一外端面133s3與第二外端面110s1相抵接。當第一外端面133s3與第二外端面110s1相抵接時,轉動部133與套筒110無法轉動,此時的位置稱為第一極限位置。 In detail, when the rotating portion 133 is rotated relative to the sleeve 110 about the first rotational direction S11, the rotating portion 133 is simultaneously translated relative to the sleeve 110 in the extending direction S12 through the thread movement until the first outer end surface 133s3 and the second outer portion The end faces 110s1 abut. When the first outer end surface 133s3 abuts against the second outer end surface 110s1, the rotating portion 133 and the sleeve 110 cannot rotate, and the position at this time is referred to as a first limit position.
如第3圖所示,注入元件130的轉動部133具有一位於套筒110內的第三外端面133s4,套筒110具有內端面110s2,第三外端面133s4與內端面110s2係相面對,第三外端面133s4與內端面110s2決定注入元件130相對套筒110的第二極限位置,如第3圖所示的位置。 As shown in FIG. 3, the rotating portion 133 of the injection member 130 has a third outer end surface 133s4 located in the sleeve 110. The sleeve 110 has an inner end surface 110s2, and the third outer end surface 133s4 faces the inner end surface 110s2. The third outer end surface 133s4 and the inner end surface 110s2 determine the second extreme position of the injection element 130 relative to the sleeve 110, as shown in Fig. 3.
詳言之,當轉動部133相對套筒110繞第二轉動方向S21轉動時,透過螺紋運動,轉動部133同時相對套筒110沿內縮方向S22平移,直到第三外端面133s4與內端面110s2相抵接。當第三外端面133s4與內端面110s2相抵接時,轉動部133與套筒110無法轉動,此時的位置稱為第二極限位置。前述的第二轉動方向S21與第一轉動方向S11係相反的二方向。 In detail, when the rotating portion 133 is rotated relative to the sleeve 110 about the second rotational direction S21, the rotating portion 133 is simultaneously translated relative to the sleeve 110 in the retracting direction S22 through the thread movement until the third outer end surface 133s4 and the inner end surface 110s2 Close to each other. When the third outer end surface 133s4 abuts against the inner end surface 110s2, the rotating portion 133 and the sleeve 110 cannot rotate, and the position at this time is referred to as a second extreme position. The aforementioned second rotational direction S21 is opposite to the first rotational direction S11.
如第3圖所示,膜片儲存元件120具有端部121。端部121例如是尖端,有利於植入器械100省力地***生物組織內。此外,如圖所示,呈尖端的端部121的斜切面可提供操作者判斷第一開孔131a朝向的技術效果。如此,即使第一開孔131a內縮於膜片儲存元件120內而不外露,透過尖端的斜切面方位仍可判斷第一開孔131a的朝向,以方便操作者以適當角度(例如,以第一開孔131a朝上的方位)操作植入器械100進入生物組織內。此外,第3圖之第一開孔131a可朝上,然亦可朝下,或朝向任何方位。由於呈尖端的端部121的斜切面可讓操作者判斷第一開孔131a的朝向,因此無論第一開孔131a朝向任何方位,都不影響操作者對於第一開孔131a位置的判斷。 As shown in FIG. 3, the diaphragm storage element 120 has an end portion 121. The end 121 is, for example, a tip that facilitates the insertion of the implant device 100 into the biological tissue with reduced effort. Further, as shown, the chamfered surface of the tip end portion 121 provides a technical effect of the operator judging the orientation of the first opening 131a. In this way, even if the first opening 131a is retracted into the diaphragm storage element 120 without being exposed, the orientation of the first opening 131a can be determined through the oblique plane orientation of the tip to facilitate the operator to at an appropriate angle (for example, The implant device 100 is operated into the biological tissue with an opening 131a facing upward. Further, the first opening 131a of Fig. 3 may face upward, or may face downward, or face any orientation. Since the chamfered surface of the tip end portion 121 allows the operator to judge the orientation of the first opening 131a, the operator's determination of the position of the first opening 131a is not affected regardless of the orientation of the first opening 131a.
第4圖繪示依照本發明另一實施例之植入器械200的外觀示意圖。植入器械200包括套筒110、膜片儲存元件120、注入元件230、氣泡產生元件140及止逆閥150。本發明實施例的植入器械200具有與前述植入器械100類似或相同的結構,不同處在於,植入器械200的注入元件230的構造與注入元件130不同。 FIG. 4 is a schematic view showing the appearance of an implant device 200 according to another embodiment of the present invention. The implant device 200 includes a sleeve 110, a diaphragm storage element 120, an injection element 230, a bubble generating element 140, and a check valve 150. The implant device 200 of the embodiment of the invention has a similar or identical structure to the implant device 100 described above, except that the implant element 230 of the implant device 200 is constructed differently than the implant element 130.
詳言之,注入元件230包括轉動部133及管體234。管體234包括第一管234A及第二管234B,其中第一管234A穿設於轉動部133、套筒110及膜片儲存元件120內,而第二管234B連接於第一管234A且位於膜片儲存元件120外。第一管234A具有擷取端131、端部234A1、注入通道134a的一部分及內端面234A2,而第二管234B具有連接端132及注入通道134a的另一部分。第一管234A例如是直管,其中擷取端131與端部234A1為直管的相對二端。 In detail, the injection element 230 includes a rotating portion 133 and a tubular body 234. The tube body 234 includes a first tube 234A and a second tube 234B, wherein the first tube 234A is disposed in the rotating portion 133, the sleeve 110 and the diaphragm storage element 120, and the second tube 234B is connected to the first tube 234A and located Outside the diaphragm storage element 120. The first tube 234A has a pick-up end 131, an end portion 234A1, a portion of the injection passage 134a, and an inner end surface 234A2, and the second tube 234B has a connection end 132 and another portion of the injection passage 134a. The first tube 234A is, for example, a straight tube, wherein the capturing end 131 and the end portion 234A1 are opposite ends of the straight tube.
在本實施例中,第一管234A的端部234A1例如是封閉端,使第一管234A之注入通道134a只透過第一開孔131a及連接端132的第一開口132a與外界連通。如此,可使氣泡產生元件140所產生的氣體大部分或甚至全部從第一開口132a進入,且大部分或甚至全部氣體從第一開孔131a輸出,以獲得最大的氣體輸出效率。此外,相較於第1C圖之連接端132的位置,本實施例之連接端132的位置更靠近第一開孔131a,以縮短第一開口132a與第一開孔131a之間的氣體傳輸路徑P1,使氣泡產生元件140所產生的氣體更快地從第一開孔131a輸出。此外,由於氣體傳輸路徑P1縮短,因此氣體的動能衰減變少,可使氣體以更大的速度自第一開孔131a輸出。 In this embodiment, the end portion 234A1 of the first tube 234A is, for example, a closed end, so that the injection passage 134a of the first tube 234A communicates with the outside through only the first opening 131a and the first opening 132a of the connecting end 132. As such, most or all of the gas generated by the bubble generating member 140 can be entered from the first opening 132a, and most or even all of the gas is output from the first opening 131a to obtain maximum gas output efficiency. In addition, the connection end 132 of the present embodiment is closer to the first opening 131a than the position of the connection end 132 of FIG. 1C to shorten the gas transmission path between the first opening 132a and the first opening 131a. P1, the gas generated by the bubble generating member 140 is outputted from the first opening 131a more quickly. Further, since the gas transmission path P1 is shortened, the kinetic energy attenuation of the gas is reduced, and the gas can be output from the first opening 131a at a higher speed.
如第4圖所示,內端面234A2與端部234A1之間的部分為實體材料。如此,可減小注入通道134a的容積,以增加或維持氣體於注入通道134a內的氣體壓力,進而使氣體以預期氣 壓從第一開孔131a輸出。 As shown in Fig. 4, the portion between the inner end surface 234A2 and the end portion 234A1 is a solid material. In this way, the volume of the injection channel 134a can be reduced to increase or maintain the gas pressure of the gas in the injection channel 134a, thereby making the gas look as expected. The pressure is output from the first opening 131a.
如第4圖所示,第二管234B與第一管234A相交。例如,第二管234B與第一管234A實質上垂直地連接,即第二管234B與第一管234A之間的夾角A1範圍介於約90度~180度之間,例如是120度,然亦可為銳角。此外,第二管234B與第一管234A可以是一體成形結構。在另一實施例中,第一管234A與第二管234B可分別形成,然後再透過螺合、卡合等方式組裝在一起。 As shown in Fig. 4, the second tube 234B intersects the first tube 234A. For example, the second tube 234B is substantially perpendicularly connected to the first tube 234A, that is, the angle A1 between the second tube 234B and the first tube 234A ranges between about 90 degrees and 180 degrees, for example, 120 degrees. It can also be an acute angle. Further, the second tube 234B and the first tube 234A may be integrally formed. In another embodiment, the first tube 234A and the second tube 234B may be separately formed and then assembled together by screwing, snapping, or the like.
請參照第5A~5F圖,其繪示第1C圖之植入器械100執行角膜植入手術的過程圖。 Please refer to FIGS. 5A-5F for a process diagram of the implantation apparatus 100 of FIG. 1C performing a corneal implantation operation.
如第5A圖所示,提供一膜片10,例如是角膜。膜片10具有半徑R1。 As shown in Fig. 5A, a membrane 10 is provided, such as a cornea. The diaphragm 10 has a radius R1.
如第5B圖所示,在擷取端131相對膜片儲存元件120伸出的狀態下,擷取提供膜片10。如圖所示,擷取端131(未繪示於第4B圖)的端壁1311具有端面1311s,第一開孔131a的中心與端面1311s的距離H1實質上等於或大於膜片的半徑。如此,當掛設在擷取端131的膜片10的中心C1大致對應第一開孔131a的位置時,幾乎整個膜片10會掛設在擷取端131上,以穩固膜片10的穩定性(若膜片10突出端面1311s,膜片10掉落的機率可能會增加)。 As shown in Fig. 5B, the diaphragm 10 is provided in a state where the pickup end 131 is extended with respect to the diaphragm storage member 120. As shown, the end wall 1311 of the extraction end 131 (not shown in FIG. 4B) has an end surface 1311s, and the distance H1 between the center of the first opening 131a and the end surface 1311s is substantially equal to or larger than the radius of the diaphragm. Thus, when the center C1 of the diaphragm 10 hanging at the capturing end 131 substantially corresponds to the position of the first opening 131a, almost the entire diaphragm 10 is hung on the capturing end 131 to stabilize the stability of the diaphragm 10. (If the diaphragm 10 protrudes from the end face 1311s, the probability of the diaphragm 10 falling may increase).
如第5C圖所示,轉動部133轉動,使管體134沿內縮方向S22平移,直到擷取端131縮進膜片儲存元件120內, 以將膜片10存放於儲存空間SP1內,以保護膜片10。由於膜片儲存元件120係透明,因此即使膜片10位於膜片儲存元件120內部,也能觀察到膜片10的狀態,如膜片10的位置及/或捲曲狀態等。 As shown in FIG. 5C, the rotating portion 133 is rotated to translate the tubular body 134 in the retracting direction S22 until the capturing end 131 is retracted into the diaphragm storage element 120. The diaphragm 10 is stored in the storage space SP1 to protect the diaphragm 10. Since the diaphragm storage element 120 is transparent, even if the diaphragm 10 is located inside the diaphragm storage element 120, the state of the diaphragm 10, such as the position and/or the curled state of the diaphragm 10, can be observed.
如第5D圖所示,以膜片儲存元件120的端部121插進生物組織20內,如眼球內。由於膜片10存放於膜片儲存元件120內的儲存空間SP1,因此在膜片儲存元件120進入生物組織20的過程中,不會因為與生物組織20的接觸而傷害到膜片10。 As shown in Fig. 5D, the end portion 121 of the diaphragm storage element 120 is inserted into the biological tissue 20, such as in the eyeball. Since the diaphragm 10 is stored in the storage space SP1 in the diaphragm storage element 120, the diaphragm 10 is not damaged by contact with the biological tissue 20 during the passage of the diaphragm storage element 120 into the biological tissue 20.
如第5E圖所示,轉動部133轉動,使管體134沿伸出方向S12平移,直到擷取端131自膜片儲存元件120內伸出,以將膜片10送入生物組織20內,如眼球的前房內。 As shown in FIG. 5E, the rotating portion 133 is rotated to translate the tubular body 134 in the extending direction S12 until the capturing end 131 protrudes from the diaphragm storage member 120 to feed the diaphragm 10 into the biological tissue 20. Such as the anterior chamber of the eyeball.
如第5F圖所示,氣泡產生元件140產生氣體G1,氣體G1進入注入通道134a,並透過第一開孔131a輸出。氣體G1可於前房的組織液中形成氣泡B1,氣泡B1將膜片10往上推出,使膜片10完全脫離植入器械100。詳言之,氣泡B1可使捲曲的膜片10攤開,攤開的膜片10更容易受到氣泡B1的浮力作用而被往上推動,使膜片10與植入器械100完全分離。 As shown in Fig. 5F, the bubble generating element 140 generates a gas G1 which enters the injection passage 134a and is output through the first opening 131a. The gas G1 can form a bubble B1 in the tissue fluid of the anterior chamber, and the bubble B1 pushes the membrane 10 upward to completely separate the membrane 10 from the implant device 100. In particular, the bubble B1 allows the curled film 10 to spread out, and the spread film 10 is more easily pushed upward by the buoyancy of the bubble B1, so that the film 10 is completely separated from the implant device 100.
然後,將植入器械100自生物組織20中抽出。由於膜片10與植入器械100完全脫離,如此在植入器械100自生物組織20抽出過程中,植入器械100不會干擾膜片10的位置,這樣可以增加手術的成功率。 The implant device 100 is then withdrawn from the biological tissue 20. Since the diaphragm 10 is completely detached from the implant device 100, the implant device 100 does not interfere with the position of the diaphragm 10 during the extraction of the implant device 100 from the biological tissue 20, which can increase the success rate of the surgery.
習知採用二種器械完成植入手術的方式中,在二種器械抽換時容易讓已置入的膜片因眼內外壓差而導致角膜組織位移,造成組織定位困難。相較於此,本發明實施例只需要一種或一支植入器械100即能完成植入手術,避免眼內外壓差的問題降低手術的成功率。 In the conventional method of implanting the two instruments, it is easy to cause the inserted diaphragm to be displaced due to the pressure difference between the inside and the outside of the two instruments, which makes the tissue positioning difficult. In contrast, the embodiment of the present invention only needs one or one implant device 100 to complete the implantation operation, and the problem of preventing the pressure difference between the inside and the outside of the eye reduces the success rate of the operation.
綜上所述,雖然本發明已以實施例揭露如上,然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾。因此,本發明之保護範圍當視後附之申請專利範圍所界定者為準。 In conclusion, the present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
