然而,当面对长条形切口时,由于柱状缝合器的缝合范围有限,术者需沿切口长轴方向多次调整缝合器的位置和角度,并重复进行插入和缝合操作
[0006]本实用新型的缝合器,通过一对可开口的活动板与多对分布在活动板两侧的子活动板,一字排开,能够使得缝合端与长条形切口的形态实现仿形匹配,且通过控制驱动杆于容纳腔轴向移动,能够驱动一对活动板和多对子活动板同步做展开或闭合运动,避免因多次插入和调整器械而导致的组织损伤风险,从而一次性完成对切口的缝合操作,不仅显著缩短了手术时间、简化了操作流程,还有效降低了患者的术后疼痛感和感染概率。

Abstract
Claims
1. A suture device, characterized in that, include: Suture needle; The guide has an internal cavity with a circular opening at one end and a first opening at the other end. A pair of openable and closable movable plates are provided in the first opening. The guide has at least one side wing and an auxiliary opening mechanism on each side. The side wing is positioned above the auxiliary opening mechanism. Each side wing and the guide have two opposing wire holes, and each side wing extends downwards to form a sub-wire post. Opposing inclined wire grooves are formed on the surfaces of the guide and the sub-wire post on opposite sides, and these wire grooves are connected to the corresponding wire holes. The auxiliary opening mechanism is provided with a pair of openable and closable sub-movable plates; A drive rod is arranged in the receiving cavity, one end of which protrudes from the receiving cavity, and the other end of which is hinged to a movable plate. The drive rod also has multiple branch ends, which are respectively hinged to the corresponding movable plate or sub-movable plate. The drive rod can move axially relative to the receiving cavity to drive a pair of movable plates and multiple pairs of sub-movable plates to perform synchronous unfolding or closing movements.
2. The suture device according to claim 1, characterized in that, The drive rod includes a first rod body, a second rod body, two branch rods, and multiple connecting blocks, wherein, The first rod body and the second rod body are rotatably connected; Two branch rods are respectively disposed opposite to each other on the outer peripheral wall of the second rod body. Two corresponding through grooves are formed on the outer peripheral wall of the guide. The branch rods can slide in the corresponding through grooves. Each branch rod has at least one end on the side away from the second rod body. A connecting block is provided on the end and the second rod body respectively. The connecting block is hinged to the movable plate or the sub-movable plate by a pin. Both the movable plate and the sub-movable plate are provided with arc-shaped holes. Two staggered limiting rods are provided in the first opening. The two limiting rods are slidably connected to the arc-shaped holes on the corresponding movable plates respectively.
3. The suture device according to claim 2, characterized in that, The first rod is rotatable relative to the receiving cavity. A U-shaped groove is provided on the first rod, and a rubber head is provided in the receiving cavity. The rubber head is slidably connected in the U-shaped groove. When the rubber head is located at the end of the U-shaped groove, the rotation angle and height position of the first rod are fixed.
4. The suture device according to claim 3, characterized in that, The end of the U-shaped groove is round, and the diameter of the end of the U-shaped groove is larger than the channel diameter of the U-shaped groove, and the rubber head is adapted to the end of the U-shaped groove.
5. The suture device according to claim 2, characterized in that, The auxiliary opening mechanism includes a connecting plate and a fixing head, wherein one end of the connecting plate is fixed to the fixing head, and the other end of the connecting plate is fixed to the guide or the fixing head; The fixed head has a second through hole and a third opening, and the second through hole is connected to the third opening. One end of the branch rod passes through the second through hole and is fixedly connected to the connecting block. The connecting block is arranged in the third opening. The sub-movable plate is arranged at the third opening. The third opening also has two staggered limiting rods. The two limiting rods are slidably connected in the arc-shaped holes opened on the corresponding sub-movable plates.
6. The suture device according to claim 1, characterized in that, The movable plate and the sub-movable plate are respectively provided with a first through hole, which is located on the extension line of the corresponding wire groove outlet. The suture needle can pass through the thread hole, the wire groove and the first through hole in sequence.
7. The suture device according to claim 6, characterized in that, A rubber block is provided in the first through hole.
8. The suture device according to claim 1, characterized in that, The length of the movable plate is greater than the length of the sub-movable plate.
9. The suture device according to claim 1, characterized in that, A second opening is provided on one side of the wire groove, and the second opening extends from the outlet of the wire groove from bottom to top to the wire hole.
10. The suture device according to claim 2, characterized in that, A knob is provided at the top of the first rod.
