Description
本發明涉及一種手術器械的構造，尤其涉及一種可重複使用的血管施夾器的驅動裝置。 The invention relates to a structure of a surgical instrument, and in particular, to a driving device of a reusable vascular clip applier.
在腹腔鏡手術的進行中，需要將血管閉合以避免血液由手術部位的切口流失，這時會使用閉合血管的手術器械，例如血管施夾器來將血管閉合。上述血管施夾器的使用方式，主要是將血管施夾器長桿狀的施夾單元伸入人體內，接著操作握把的部分帶動施夾單元動作，以施夾單元前端的夾持部夾合依次輸送到夾持部內側的血管夾的方式，將血管夾鉗壓在血管上來將血管閉合。 During the laparoscopic surgery, the blood vessel needs to be closed to avoid blood loss from the incision at the surgical site. At this time, a surgical instrument that closes the blood vessel, such as a vascular clip applier, is used to close the blood vessel. The use method of the vascular clip applier is mainly to extend the rod-shaped clip applicator unit of the vascular clip applicator into the human body, and then operate the grip part to drive the clip applier unit to clamp the clamping part at the front end of the clip applier The vascular clamps that are sequentially delivered to the inside of the clamping section are pressed against the blood vessels to close the blood vessels.
現有的血管施夾器由於其前端的構造在使用時會伸入人體內，為避免血液污染的狀況發生，一般的血管施夾器都是設計成一次性使用的拋棄式構造，例如TW專利申請案號第104118985號「自動施夾器」發明專利申請案(公開號第201642812號)，是在外套管的內部設有施夾單元，在施夾單元前端設有夾持部，配合夾持部設有推動各血管夾向前的進夾單元，在該施夾單元後端部的前、後位置各套設一第一套管以及一第二套管，利用第一套管前移的動作帶動該夾持部夾合，第一套管前移過程的前段會帶動第二套管往前移動，第二套管會在第一套管前移過程的後段脫離與第一套管同動的狀態，這時第二套管可受驅動後移，利用第二套管前後移動的動作可帶動進夾單元推進一血管夾進入該夾持部的內側。 Existing vascular clip appliers are inserted into the human body during use due to their front-end structure. In order to avoid blood contamination, general vascular clip appliers are designed as disposable disposable structures, such as the TW patent application. Case No. 104118985 "Automatic clip applier" invention patent application (Publication No. 201642812) is provided with a clip applying unit inside the outer sleeve, and a clamping portion is provided at the front end of the clip applying unit to cooperate with the clamping portion A clamping unit for pushing forward each blood vessel clamp is provided, and a first sleeve and a second sleeve are set at the front and rear positions of the rear end of the clamping unit, and the first sleeve is moved forward by the action The clamping part is clamped, the first section of the first casing forward process will drive the second casing forward, and the second casing will be separated from the same movement with the first casing at the rear section of the first casing forward process. At this time, the second cannula can be moved back by being driven, and the movement of the second cannula back and forth can drive the clamping unit to advance a blood vessel clamp into the inside of the clamping portion.
上述現有的自動施夾器驅動該施夾單元動作的構造，是以壓動握持單元的方式，透過第一、第二連接件帶動對應的連結件，以嵌套在第一套管或第二套管的連結件帶動第一套管以及第二套管動作，當自動施夾器使用完畢後將整體拋棄。上述自動施夾器的施夾單元，其第一、第二套管與握持單元的連結件之間是嵌套的可分離結構，也就是該施夾單元是能與握持單元分離的獨立構造，但由於該握持單元是與施夾單元固定的設計，在自動施夾器每次使用後，握持單元都要隨著如此類型的施夾單元構造一同被拋棄，使得自動施夾器的使用成本較高。 The structure of the existing automatic clip applier for driving the clip applying unit is to press the holding unit to drive the corresponding connecting member through the first and second connecting members to be nested in the first sleeve or the second The connecting piece of the sleeve drives the movement of the first sleeve and the second sleeve, and will be discarded after the automatic clip applier is used. The clip applying unit of the automatic clip applier has a nested and separable structure between the first and second sleeves and the connecting member of the holding unit, that is, the clip applying unit is an independent structure that can be separated from the holding unit. However, because the holding unit is fixed to the clip applying unit, after each use of the automatic clip applicator, the holding unit must be discarded along with the structure of this type of clip applying unit, making the automatic clip applier The use cost is higher.
由於現有的血管施夾器是拋棄式的構造，其握持單元不能重複使用，因此在手術後需要將整個血管施夾器拋棄因此成本較高。為此，本發明設計可重複裝填現有施夾單元類型構造的驅動裝置，達到血管施夾器的驅動裝置可重複使用的經濟效果。 Since the existing vascular clip applier is a disposable structure, its holding unit cannot be reused. Therefore, the entire vascular clip applier needs to be discarded after the operation, so the cost is high. For this reason, the present invention designs a driving device capable of repeatedly filling the existing clip applying unit type structure, and achieves the economical effect that the driving device of the vascular clip applier can be reused.
