    • Various embodiments provide surgical cutting devices and systems for orthopedic and other procedures. Specific embodiments provide saw devices for accessing and cutting subjacent bone and other tissue while minimizing injury to surrounding tissue. One embodiment provides a transverse acting saw blade for performing surgical cuts to bone tissue with minimal injury to surrounding tissue. The blade comprises an elongated member having a first portion and a second portion and a longitudinal and lateral axis. The first portion is configured to engage a drive source to produce longitudinal movement of the first portion that is atraumatic to surrounding tissue. The second portion includes a cutting surface. The longitudinal movement of the first portion is converted to a lateral movement of the second portion that is sufficient to cut engaged bone tissue with the cutting surface. The movement of the second portion is substantially transverse to the movement of the first portion.
    • 各种实施例提供用于矫形和其他手术的外科切割装置和系统。 具体实施例提供用于进入和切割下面的骨骼和其他组织的锯装置,同时使对周围组织的损伤最小化。 一个实施例提供了一种横向作用锯片,用于对周围组织的损伤以最小的损伤进行骨组织的手术切割。 刀片包括具有第一部分和第二部分以及纵向和横向轴线的细长部件。 第一部分被配置为接合驱动源以产生对周围组织无伤害的第一部分的纵向运动。 第二部分包括切割表面。 第一部分的纵向运动被转换为第二部分的横向移动,其足以切割与切割表面接合的骨组织。 第二部分的运动基本上横向于第一部分的运动。

    • A surgical device for closing an incision created by a trocar or similar surgical device is disclosed. The surgical device comprises a support member within which are disposed a first and second needle positioning means. Each of these means carries a suture needle in retrorse configuration relative to the distal end of the support member. The needles can be retracted or deployed relative to the support member in a plurality of desired positions. In operation, the needles are deployed at a desired distance from the edge of the incision. The surgeon then pulls the device out of the body of the patient, thereby capturing and pulling the needles through first the peritoneum followed by the fascia. Needle capture means are provided which retain and remove the needles after the peritoneum and fascia are sutured, leaving the loose ends of the suture thread which can then be tied off below skin level to close the incision.
    • 公开了一种用于封闭由套管针或类似手术装置产生的切口的手术装置。 手术装置包括支撑构件,在支撑构件内设置有第一和第二针定位装置。 这些装置中的每个装置相对于支撑构件的远端携带以反向构造的缝合针。 针可以相对于支撑构件在多个期望位置中缩回或展开。 在操作中,针从切口的边缘以期望的距离展开。 外科医生然后将装置从患者的身体拉出,从而首先将针头收紧并拉出腹膜,然后是筋膜。 提供针捕获装置,其在腹膜和筋膜缝合之后保留和移除针,留下缝合线的松散端,然后将其缝合在皮肤层下方以封闭切口。
