Sometimes, during the operation, the tissues and organs in the patient's abdominal cavity will block or cover the parts that need to be targeted. At this time, the doctor needs to reuse the existing instruments. The tools are opened and supported, which greatly hinders the operation, delays the operation time, and virtually increases the risk of the operation.

Thecollet 14 cooperates with the tissueclip fixing shell 11 to realize the function of clamping tissues and organs, and thefirst linkage member 12 is connected to the tissue clip. When thefixed shell 11 slides relatively, thecollet 14 is driven to open and close, and when the first resetelastic member 13 is in a natural state, thecollet 14 is in a clamping state.

如图3所示，组织夹固定壳11的一端凸设有一圈第一凸边113，组织夹固定壳11上开设有贯穿其侧壁的第一通槽111，夹头14的铰接位置在第一通槽111处，组织夹固定壳11的一端开设有连通至第一通槽111的供第一联动件12滑动的第一开槽112，第一联动件12伸入组织夹固定壳11的一端沿第一通槽111的方向凸设有两个第一卡块122，第一卡块122伸出组织夹固定壳11，第一复位弹性件13可以为弹簧等具有弹性的物件，在本实施例中为弹簧，第一复位弹性件13的一端与第一卡块122相抵，另一端与第一凸边113相抵，以实现第一联动件12与组织夹固定壳11发生相对滑移的时候，复位至夹头14处于夹持的状态的位置。As shown in FIG. 3 , one end of the tissueclip fixing shell 11 is protruded with a circle of first flanges 113 , the tissueclip fixing shell 11 is provided with a first through groove 111 penetrating its side wall, and the hinged position of theclip head 14 is at the first through groove 111 .

Thesecond linkage 22 is connected to the retractor A second resetelastic member 23 is arranged between theclip fixing shells 21, aclamping component 24 is arranged on the retractingclip fixing shell 21, and thesecond linkage member 22 and the retractingclip fixing shell 21 are relatively sliding to drive the clamping component. 24 is opened and closed, and when the second resetelastic member 23 is in a natural state, theclamping assembly 24 is in a clamping state.

如图5所示，牵开夹固定壳21的一端凸设有一圈第二凸边213，牵开夹固定壳21上开设有贯穿其侧壁的第二通槽211，牵开夹固定壳21的一端开设有连通至第二通槽211的供第二联动件22滑动的第二开槽212，第二联动件22伸入牵开夹固定壳21的一端沿第二通槽211的方向凸设有两个第二卡块221，第二卡块221伸出牵开夹固定壳21，第二复位弹性件23与第一复位弹性件13相似，可为弹簧，其一端与第二卡块221相抵，另一端与第二凸边213相抵，第二卡块221向靠近夹块241的方向延伸并与夹块241连接。夹持组件24包括两个转动连接在牵开夹固定壳21一端的夹块241，夹块241的形状结构可依据调整，可为平面的块状结构，亦可为钩状结构等。夹块241上开设有滑槽243，第二联动件22上凸设有与滑槽243配合的滑块242，通过滑槽243与滑块242的配合以及第二联动件22与牵开夹固定壳21之间的滑动实现夹块241的开合。As shown in FIG. 5 , one end of the retractionclip fixing shell 21 is protruded with a secondconvex edge 213 , and the retractionclip fixing shell 21 is provided with a second throughgroove 211 penetrating the side wall thereof.
