具体实施方式
请参阅图1，其例示说明了根据本发明医用支架操作系统一具体实施例的示意图。如图1所示实施例，医用支架操作系统100包含操作部1100、握 持部1200、管鞘部1300、支架移动部(图中未示出，于后将详细说明)、光学感测装置(图中未示出，于后将详细说明)以及保护部1600。管鞘部1300为中空组件，其内具有第一空腔，该第一空腔沿着管鞘部1300的长度方向810延伸。较佳地，管鞘部1300的管鞘末端1320处可具有侧向连通出口1310(侧向连通出口1310的设置方式可参考申请号第110103890号的台湾地区发明专利，其发明名称为“手术用医疗装置及其系统”。在此并以引用记载方式将申请号第110103890号的台湾地区发明专利全文并入本文中)。握持部1200为中空组件，其内具有第二空腔。管鞘部1300以可拆卸的方式连接握持部1200。操作部1100以可移动的方式连接握持部1200，其中，操作部1100具有第一操作端部以及第二操作端部，操作部1100的第一操作端部设置于握持部1200的第二空腔内，而操作部1100的第二操作端部设置于握持部1200外。较佳地，操作部1100与握持部1200之间的连接关系以及作动关系类似于一般医用针筒装置的推杆部与针筒部。
医用支架操作系统1000的支架移动部连接于操作部1100的第一操作端部，且支架移动部延伸于第一空腔以及第二空腔内。在通过医用支架操作系统100以操作(或移动)医用支架的过程中，医用支架可先放置于管鞘部1300内(较佳地，医用支架先放置于管鞘部1300内，靠近管鞘部1300的管鞘末端1320的位置)，并使医用支架接触支架移动部的末端。使用者可接着通过将操作部1100相对于握持部1200移动，而通过连接于操作部1100的支架移动部使医用支架移动，并逐渐将医用支架推出于管鞘部1300外。保护部1600以可拆卸的方式装设(例如塞设于)于管鞘部1300的管鞘末端1320，藉以保护管鞘部1300以及位于管鞘部1300内的支架移动部及光学感测装置。其中，光学感测装置的传输部1520(例如传输线)可延伸设置于第一空腔以及第二空腔内。应了解，在使用医用支架操作系统100的过程中，即可无需使用保护部1600，而可将保护部1600自管鞘部1300的管鞘末端1320移除。在一具体实施例中，也可无需具有保护部1600。
请参阅图2A，其例示说明了根据本发明医用支架操作系统的握持部以及 光学感测装置一具体实施例的示意图。如图2A所示实施例，握持部2200包含握持主体部2210以及延伸部(或可称为握持延伸部)2220，握持主体部2210连接延伸部2220。握持主体部2210具有卡合孔(可称为握持卡合孔)2232、2234、2236、长型通孔2240以及握持卡合部2250。其中，卡合孔2232较长型通孔2240更靠近延伸部2220，长型通孔2240沿着握持部2200的长度方向延伸设置于握持部2200的握持主体部2210上。较佳地，长型通孔2240的通孔端部2242设置于卡合孔2234与卡合孔2232之间。医用支架操作系统的光学感测装置包含感测部2510以及传输部2520，感测部2510连接传输部2520。感测部2510设置(或连接)于延伸部2220的末端(可称为握持末端)处，传输部2520延伸设置于握持部2200的第二空腔内(详细而言，传输部2520延伸设置于延伸部2220内以及主体部2210内，并自主体部2210向外延伸)。感测部2510可在医用支架操作系统的操作过程中获取体内影像，并可通过传输部将所获取到的影像传送至显示设备以供用户观看影像。在一具体实施例中，传输部2520可具有处理部2530，其可协助处理感测部2510所获取到的影像。
请参阅图2B，其例示说明了根据本发明医用支架操作系统的操作部以及支架移动部一具体实施例的示意图。如图2B所示实施例，操作部2100具有第一操作端部2110、第二操作端部2120、卡合部2130以及突出部2140。卡合部2130以及突出部2140均设置于第一操作端部2110上。支架移动部2400的一端连接操作部2100，支架移动部2400的另一端(可称为末端或支架移动末端)具有推动部2410。如此，当使用者移动(或操作)操作部2100时，支架移动部2400即会随着操作部2100移动，并可通过推动部2410以推动医用支架。在一具体实施例中，支架移动部2400的末端不具有推动部，而是具有勾合部。如此，使用者即可通过勾合部以勾住医用支架，并可接着通过移动(或操作)操作部2100以拉动医用支架。图3即例示说明了支架移动部2400的末端具有勾合部的一具体实施例，如图3所示实施例，支架移动部3400的末端具有勾合部3420。
请参阅图2C，其例示说明了根据本发明医用支架操作系统的管鞘部一具体实施例的示意图。如图2C所示实施例，管鞘部2300具有管鞘主体部2370、管鞘延伸部2330、液体输送部2340、2350以及卡合孔(可称为管鞘卡合孔)2360。管鞘主体部2370连接管鞘延伸部2330，液体输送部2340、2350连接管鞘主体部2370，卡合孔2360设置于管鞘主体部2370上。液体输送部2340、2350连通管鞘部2300的第一空腔，如此，即可经由液体输送部2340、2350将液体(例如水、生理食盐水等，但不以此为限)输送至该管鞘部2300内。
请同时参阅图2A、图2B以及图2C。支架移动部2400可延伸设置于管鞘部2300的第一空腔以及握持部2200的第二空腔内。支架移动部2400的末端可接触医用支架。例如当支架移动部2400的末端具有推动部2410时，则可通过支架移动部2400的推动部2410以将医用支架逐渐推出于管鞘部2300的外部。而当支架移动部2400的末端具有勾合部时，则可通过支架移动部2400的勾合部以将医用支架逐渐拉进管鞘部2300的内部(即第一空腔内)。
支架移动部2400以及握持部2200的延伸部2220可同时延伸设置于管鞘部2300的第一空腔。较佳地，当支架移动部2400的末端具有推动部2410时，推动部2410可呈中空圆筒状，且推动部2410以可相对于传输部2520以及延伸部2220移动的方式而套合于该传输部2520以及延伸部2220。图4即例示说明了管鞘部、延伸部以及推动部一具体实施例的局部示意图，如图4所示实施例，握持延伸部4220以及支架移动部4400设置于管鞘延伸部4330内。支架移动部4400的末端具有推动部4410，推动部4410呈中空圆筒状，且推动部4410以可相对于握持延伸部4220移动的方式而套合于握持延伸部4220。其中，由于光学感测装置的传输部延伸设置于握持延伸部4220内，因此，推动部4410也是以可相对于传输部移动的方式而套合于传输部。通过此种配置方式，当用户通过使操作部相对于握持部移动，而使推动部4410相对于握持延伸部4220以及传输部移动时，位于握持延伸部4220的末端处的感测部4510仍可继续获取影像，而不受到推动部4410的影响。较佳地，管鞘部呈透明管状体，或至少管鞘部的管鞘延伸部4330呈透明管状体，如此可避 免管鞘部的管鞘延伸部4330遮挡到感测部4510的视野。在一具体实施例中，传输部部分延伸设置于握持延伸部4220内(也即传输部部分延伸设置于管鞘部的第一空腔内)，且传输部部分延伸设置于握持部的第二空腔内。较佳地，在感测部4510获取影像的过程中，感测部4510设置于管鞘部的管鞘延伸部4330内，且被放置于(或设置于)管鞘延伸部4330的管鞘末端处。其中，感测部4510可视需求而完全设置于管鞘部内，或略为露出于管鞘末端外。而当握持延伸部4220相对于管鞘延伸部4330移动时(例如握持延伸部4220自管鞘延伸部4330内被移除)，感测部4510即可随着握持延伸部4220而相对于管鞘延伸部4330移动(例如感测部4510可随着握持延伸部4220而自管鞘延伸部4330内被移除)。
请参阅图5，其例示说明了管鞘部、延伸部以及勾合部一具体实施例的局部示意图。如图5所示实施例，握持延伸部5220以及支架移动部5400设置于管鞘延伸部5330内，支架移动部5400的末端具有勾合部5420。当使用者通过使操作部相对于握持部移动，而使勾合部5420相对于握持延伸部5220以及传输部移动时，位于握持延伸部5220的末端处的感测部5510仍可继续获取影像，而不受到勾合部5420的影响。较佳地，管鞘部呈透明管状体，或至少管鞘部的管鞘延伸部5330呈透明管状体，如此可避免管鞘部的管鞘延伸部5330遮挡到感测部5510的视野。较佳地，在感测部5510获取影像的过程中，感测部5510设置于管鞘部的管鞘延伸部5330内，且被放置于(或设置于)管鞘延伸部5330的管鞘末端处。其中，感测部5510可视需求而完全设置于管鞘部内，或略为露出于管鞘末端外。而当握持延伸部5220相对于管鞘延伸部5330移动时(例如握持延伸部5220自管鞘延伸部5330内被移除)，感测部5510即可随着握持延伸部5220而相对于管鞘延伸部5330移动(例如感测部5510可随着握持延伸部5220而自管鞘延伸部5330内被移除)。
本发明的医用支架操作系统所操作(或移动)的医用支架可具有第一撑开段、第二撑开段以及第三撑开段，第三撑开段设置于第一撑开段与第二撑开段之间(此类医用支架可参考前述申请号第110103890号的台湾地区发明 专利。然而，应了解，本发明的医用支架操作系统并非仅可用于此类的医用支架)。本发明的医用支架操作系统可具有阶段式移动机构，其中，操作部可通过阶段式移动机构而阶段式地相对于握持部移动，并进而使第一撑开段、第三撑开段以及第二撑开段阶段式地被支架移动部依序推出于管鞘部外。阶段式移动机构可例如为前述申请号第110103890号的台湾地区发明专利中，图7至图8C所述的容纳装置，但不以此为限。
请回参图2A、图2B以及图2C，医用支架操作系统的阶段式移动机构可例如为握持部2200的握持主体部2210具有卡合孔2232、2234、2236，操作部2100的第一操作端部2110具有卡合部2130，卡合部2130在操作部2100相对于握持部2200移动的过程中，可与卡合孔2232、2234、2236其中一者相卡合。其中，当卡合部2130与卡合孔2236(卡合孔2236可称为第一卡合孔)相卡合时，医用支架的第一撑开段被支架移动部2400的推动部2410推出于管鞘部2300的管鞘末端2320外。当卡合部2130与卡合孔2234(卡合孔2234可称为第二卡合孔)相卡合时，医用支架的第三撑开段被支架移动部2400的推动部2410推出于管鞘部2300的管鞘末端2320外。当卡合部2130与卡合孔2232(卡合孔2232可称为第三卡合孔)相卡合时，医用支架的第二撑开段被支架移动部2400的推动部2410推出于管鞘部2300的管鞘末端2320外。通过上述的阶段式移动机构，使用者即可阶段式地将医用支架的第一撑开段、第三撑开段以及第二撑开段分别置放于人体内的正确位置(第一撑开段、第三撑开段以及第二撑开段各自的正确放置位置可参见前述申请号第110103890号的台湾地区发明专利)。较佳地，当卡合部2130与卡合孔2232、2234、2236其中任一者卡合时，使用者仍可通过施加较大的力，以使卡合部2130与对应的卡合孔解除卡合，并让操作部2100可相对于握持部2200而继续被推或拉动。
操作部2100的突出部2140可经由长型通孔2240向外突出(其间的配置方式可参考图1所绘示的突出部1140以及长型通孔1240)，且突出部2140可沿着握持部2200的长型通孔2240移动。如此，操作部2100相对于过持部 2200移动时，突出部2140将不会影响操作部2100与过持部2200之间的作动。但是，在卡合部2130自卡合孔2234向卡合孔2232移动的过程中，于卡合部2130与卡合孔2232相卡合之前，突出部2140会先接触到长型通孔2240的通孔端部2242，并使操作部2100无法沿着推出方向820相对于握持部2200继续移动。此时，医用支架的第二撑开段部分露出于管鞘部2300的管鞘末端2320外。此机制可避免使用者在操作部2100的过程中，因施力过度而令第二撑开段太快被完全推出于管鞘末端2320外，进而导致第二撑开段被放置于错误位置，或导致医用支架伤害到人体的情况发生。
当突出部2140接触到长型通孔2240的通孔端部2242时，使用者可对突出部2140施加第一外力(第一外力可例如为在垂直于操作部2100的延伸方向上，按压突出部214的力)，使突出部2140离开通孔端部2242并离开该长型通孔2240。使用者可接着对操作部2100施加第二外力(即继续朝方向830推动操作部2100)，以使操作部2100沿着推出方向820相对于握持部2200移动，并使医用支架的第二撑开段被支架移动部2400的推动部2410推出于管鞘部2300的管鞘末端2320外。
握持部2200的握持卡合部2250可与管鞘部2300的卡合孔2360相卡合，以将握持部2200较稳固地连接于管鞘部2300。使用者并可依需求而使卡合部2250与卡合孔2360解除卡合，并进一步将握持部2200与管鞘部2300彼此分开。例如在用户通过医用支架操作系统以将医用支架自患者体内向外移除的过程中，即可先通过支架移动部2400的勾合部以勾住医用支架，接着在将卡合部2250与卡合孔2360解除卡合，并通过拉动操作部2100及/或握持部2200，以将支架移动部2400及/或握持部2200的延伸部2220自管鞘延伸部2330内向外移除。如此，医用支架即会随着勾合部被移除于人体外。
至此，本发明的医用支架操作系统已经由上述说明及附图加以说明。然而，应了解，本发明的各个具体实施例仅是作为说明的目的，在不脱离本申请的保护范围与精神下可进行各种改变，且均应包含于本发明的专利范围中。因此，本说明书所描述的各具体实施例并非用以限制本发明，本发明的真实 范围与精神揭示于以下权利要求书。
