    • A purse string suturing instrument is provided for quickly and effectively forming a purse string suture in tubular tissue through relatively small cannulas placed in the body. The instrument includes a pair of elongated jaws, each having a row of spaced-apart uniform-size teeth. The jaws are hinged together at one end to clamp the tubular tissue therebetween. The two rows of teeth are offset with respect to each other so that they mesh when the jaws are closed. A single operating mechanism is provided to articulate the pair of jaws with respect to a longitudinal axis of the suturing instrument and actuate the jaws between an open position and a clamping position. The jaws are inserted through a cannula and positioned to close around the tissue to be sutured. The rows of teeth bend the tissue therebetween into a wavelike configuration. A pair of needles, the ends of each being connected to a single length of suture, is then inserted through passageways provided through the teeth. An encircling series of stitches are thus formed in the wall of the tubular tissue to create a purse string suture. The needles and the suturing instrument are then withdrawn through the cannula. The tubular tissue can be snugly fitted over an anastomosis ring or the like by drawing and tying the purse string suture.
    • 提供了一种钱包缝合器械,用于通过放置在身体中的相对小的插管快速有效地在管状组织中形成钱包线缝合线。 该仪器包括一对细长的钳口,每个具有一排间隔开均匀尺寸的齿。 钳口在一端铰接在一起,以夹紧管状组织。 两排齿相对于彼此偏移,使得当颚关闭时它们啮合。 提供单个操作机构以相对于缝合器械的纵向轴线来铰接该对钳口,并且在打开位置和夹紧位置之间致动钳口。 夹钳插入穿过套管并定位成围绕要缝合的组织。 齿排使其间的组织弯曲成波浪形构型。 然后通过通过牙齿提供的通道插入一对针,每个针的一端连接到单个缝合线。 因此,在管状组织的壁中形成环绕的线圈系列以产生钱包线缝合线。 然后通过套管抽出针头和缝合器械。 管状组织可以通过拉丝和捆扎钱包缝合线紧密地装配在吻合环等上。

    • A medical fastener (18), preferably bioabsorbable, is used for repairing torn soft tissue, particularly meniscal tissue (16). The fastener (18) can have an enlarged head (22) at the proximate end to engage meniscal tissue (16) adjacent to a tear (14), and a pointed distal tip (21) at the other end to ease insertion of the fastener (18) into the meniscus (16). The shank (20) of the fastener (18) bridges across the tear (14). Opposite ends of the shank (20) are secured in the meniscal tissue (16) by a medical adhesive, preferably bioabsorbable, and preferably at locations remote from the tear (14) so as not to interfere with healing of the tear (14). The fastener (18) can have a blind bore (24) opening through the head (22) of the fastener (18) and extending through the shank (20) to a location close to the tip (21) and generally radial holes (26) communicating between the bore (24) and the exterior of the shank (20). The medical adhesive can be injected through the bore (24) for passage outward through the holes (26).
    • 医疗紧固件(18),优选地是生物可吸收的,用于修复被撕毁的软组织,特别是半月板组织(16)。 紧固件(18)可以在近端处具有扩大的头部(22),以与邻近泪液(14)的半月板组织(16)接合,并且在另一端处具有尖锐的远端尖端(21),以便于紧固件 (18)进入弯月面(16)。 紧固件(18)的柄(20)穿过泪液(14)。 柄(20)的相对端通过医疗粘合剂固定在半月板组织(16)中,优选地是生物可吸收的,优选在远离泪液(14)的位置处,以便不干扰泪液(14)的愈合。 紧固件(18)可以具有穿过紧固件(18)的头部(22)的盲孔(24),并且通过柄部(20)延伸到靠近尖端(21)的位置,并且大致为径向孔 )连通孔(24)和柄(20)的外部。 医用粘合剂可以通过孔(24)注入,以通过孔(26)向外通过。
