Description

套管裝置Casing device

本發明係有關一種套管結構，尤指一種具有氣密結構之套管裝置。The invention relates to a casing structure, especially a casing device with an airtight structure.

穿刺套管係為一種常見的外科手術所使用的器具之一，此種穿刺套管及其附件主要用於提供各式外科手術器械，如腹腔、骨盤或胸腔等，以產生提供內視鏡等器具通過之通道，一般來說，穿刺套管的結構主要包括一支內管及一支外管，內管用於穿刺腹腔，並帶入具有固定功能的外管。The puncture sleeve is one of the instruments used in a common surgical operation. This puncture sleeve and its accessories are mainly used to provide various surgical instruments, such as the abdominal cavity, pelvis or chest cavity, etc., to produce an endoscope, etc. The channel through which the appliance passes. Generally speaking, the structure of the puncture sleeve mainly includes an inner tube and an outer tube. The inner tube is used to puncture the abdominal cavity and brought into the outer tube with a fixed function.

而目前常見的套管結構多為矽膠熱壓成型產品，於該套管的開口處設計，為了符合其他穿接的外科手術器械所產生的貼合度因素，其開口處的形狀包括一字形、十字形或是多邊形等設計，皆為克服與圓形器械插入時與圓形貼合度的大小。At present, most of the common tube structures are silicone hot-pressed products, which are designed at the opening of the tube.

續參閱第一圖。係為本發明之立體結構分解圖。本發明之套管裝置再包括一上蓋2，該上蓋2係與該主體1之底座114對應接合，並將前述之座體12罩設於內部，該上蓋2之頂部位置設有一開孔21，該開孔21位置恰對應於該第一滾輪13與該第二滾輪14合併時之中心位置。Continue to the first picture. It is an exploded view of the three-dimensional structure of the present invention. The sleeve device of the present invention further includes an upper cover 2, which is correspondingly engaged with the base 114 of the main body 1, and covers the aforementioned seat body 12 inside, and an opening 21 is provided on the top of the upper cover 2, The position of the opening 21 corresponds to the center position when the first roller 13 and the second roller 14 merge.

請參閱第四圖，係為本發明之結構剖視圖。如圖所示，本發明之套管裝置在未使用時，設於座體12上之該第一滾輪13與該第二滾輪14呈現相互貼抵之狀態，且該第一滾輪13之第二曲面凹槽135與該第二滾輪14之第四曲面凹槽145位置係分別朝外，由該第一滾輪13與該第二滾輪14之實心位置相互貼抵，以形成密封狀態，如第五圖之結構俯視圖所示，致使該管體11內部不外露。彈性元件15僅輔助提供回復力予滾輪和轉桿，並限制滾輪和轉桿位移。Please refer to the fourth figure, which is a sectional view of the structure of the present invention. As shown in the figure, when the sleeve device of the present invention is not in use, the first roller 13 and the second roller 14 provided on the seat body 12 are in a state of being in contact with each other, and the second of the first roller 13 The positions of the curved groove 135 and the fourth curved groove 145 of the second roller 14 are outward, respectively, and the solid positions of the first roller 13 and the second roller 14 abut against each other to form a sealed state, such as the fifth The structure of the figure is shown in a top view, so that the inside of the tube body 11 is not exposed. The elastic element 15 only assists in providing restoring force to the roller and the rotating rod, and limits the displacement of the roller and the rotating rod.

續參閱第六圖之使用狀態立體圖，如圖所示，本發明之套管裝置另包括一套針3，該套針3係包括一針體31，於該針體31之頂端具有一握座32，該套針3係用以插設於該主體1內；如第七圖之使用狀態剖視圖所示，該第一滾輪13的該第一曲面凹槽134和該第二滾輪14的該第三曲面凹槽144相互貼抵。當該套針3之針體31尖端部自該上蓋2之開孔21穿入後，該針體31尖端部頂掣該第一滾輪13與該第二滾輪14之間的位置，致使該第一滾輪13與該第二滾輪14相對旋轉，使該第一滾輪13的該第一曲面凹槽134和該第二滾輪14的該第三曲面凹槽144貼抵包覆於該針體31尖端部周圍，如第八圖所示。Continue to refer to the perspective view of the sixth state of use. As shown in the figure, the cannula device of the present invention further includes a set of needles 3. The set of needles 3 includes a needle body 31 with a grip at the top of the needle body 31 32, the trocar 3 is used to be inserted into the main body 1; as shown in the cross-sectional view of the use state of the seventh figure, the first curved groove 134 of the first roller 13 and the first surface of the second roller 14 The three curved grooves 144 abut against each other. When the tip portion of the needle body 31 of the trocar 3 penetrates through the opening 21 of the upper cover 2, the tip portion of the needle body 31 presses the position between the first roller 13 and the second roller 14 so that the first A roller 13 rotates relative to the second roller 14 so that the first curved groove 134 of the first roller 13 and the third curved groove 144 of the second roller 14 abut against the tip of the needle body 31 Around the department, as shown in the eighth figure.

更進一步地，當針體31再次往管體11內部推進，如第九圖所示，針體31尖端部遠離第一滾輪13和第二滾輪14 ，取而代之地，針體31中端部貼抵第一滾輪13和和第二滾輪14，換言之，第一滾輪13之第二曲面凹槽135和第二滾輪14之第四曲面凹槽145貼抵包覆該針體31之中端部。於最佳實施例中，第一曲面凹槽134和第三曲面凹槽144之曲度係小於第二曲面凹槽135和第四曲面凹槽145之曲度，故第一曲面凹槽134、第三曲面凹槽144貼抵包覆針體31之尖端部，第二、四曲面凹槽貼抵包覆針體31之中端部。於上述最佳實施例中，第一滾輪13和第二滾輪14係由橡膠等軟性材質所組成，據此，除了不同曲度之曲面凹槽以適應針體31之不同部位之尺寸之外，軟性材質之滾輪更有助於滾輪貼抵針體31，更能廣泛適應於不同形狀尺寸之針體31。而當針體31離開管體11時，彈性元件15輔助提供回復力予第一滾輪13和第二滾輪14，使第一滾輪13與第二滾輪14回復到相互貼抵之初始狀態，另外，彈性元件15更可以限制第一滾輪13和第二滾輪14的位移。Furthermore, when the needle body 31 is pushed into the tube body 11 again, as shown in the ninth figure, the tip of the needle body 31 is far away from the first roller 13 and the second roller 14. Instead, the middle end of the needle body 31 abuts The first roller 13 and the second roller 14, in other words, the second curved groove 135 of the first roller 13 and the fourth curved groove 145 of the second roller 14 abut against the middle end of the needle body 31. In the preferred embodiment, the curvature of the first curved groove 134 and the third curved groove 144 is smaller than the curvature of the second curved groove 135 and the fourth curved groove 145, so the first curved groove 134, The third curved groove 144 abuts against the tip of the covering needle body 31, and the second and fourth curved grooves abut against the middle end of the covering needle body 31. In the above preferred embodiment, the first roller 13 and the second roller 14 are made of soft materials such as rubber. According to this, in addition to the curved grooves with different curvatures to adapt to the sizes of different parts of the needle body 31, The roller made of soft material helps the roller to abut the needle body 31, and can be widely adapted to the needle body 31 of different shapes and sizes. When the needle body 31 leaves the tube body 11, the elastic element 15 assists in providing a restoring force to the first roller 13 and the second roller 14, so that the first roller 13 and the second roller 14 return to the initial state of mutual contact. In addition, The elastic element 15 can further limit the displacement of the first roller 13 and the second roller 14.

於最佳實施例中，第一開口(未圖示)形成於第一滾輪13和第二滾輪14之間，並與穿孔115對應，第一開口之孔徑大小隨滾輪曲面凹槽不同而有所變化。參閱第七圖所示，第一滾輪13與第二滾輪14尚未受到外力推動，第一開口尚未形成(相當於密封狀態)；進一步地，當針體31之尖端部碰觸第一滾輪13和第二滾輪14之間，並於握座32施加推進力，第一滾輪13順時針轉動(如圖中虛線箭頭所示)以及第二滾輪14逆時針轉動(如圖中虛線箭頭所示)，致使當第一曲面凹槽134與第三曲面凹槽144相面對，此時第一開口之孔徑大小相符於針體31之尖端部(如第八圖所示)管徑大小，針體31始於插設於管體11內；復推進針體31，第一滾輪13再次順時針轉動(如第九圖虛線箭頭所示)，第二滾輪14再次逆時針轉動(如第九圖虛線箭頭所示)，致使第二曲面凹槽135與第四曲面凹槽145相面對，此時第一開口之孔徑大小相符於針體31之中端部(如第九圖所示)管徑大小。換言之，因第二、四曲面凹槽135、145之曲度大於第一、三曲面凹槽134、144之曲度，故第二曲面凹槽135與第四曲面凹槽145所形成之第一開口之孔徑大於第一曲面凹槽134與第三曲面凹槽144所形成之孔徑，如此一來，廣泛適應針體31之不同部位。In the preferred embodiment, a first opening (not shown) is formed between the first roller 13 and the second roller 14 and corresponds to the perforation 115. The aperture size of the first opening varies with the groove of the roller curved surface Variety.
