摘要： A staple having a crown and first and second deformable members extending from the crown. In at least one embodiment, the staple further includes a base connecting the first and second deformable members where the base is not entirely co-planar with the first and second deformable members. In these embodiments, the crown can be overmolded onto, or attached to, the base and provide a larger and/or more stable tissue-contacting surface for supporting the tissue captured by the staple. As a result, the possibility of the staple being pulled through the tissue and/or the tissue tearing within or around the staple is reduced.
摘要翻译：具有冠部的钉，其具有从冠部延伸的第一和第二可变形构件。在至少一个实施例中，订书钉还包括连接第一和第二可变形构件的底座，其中基座与第一和第二可变形构件不完全共面。在这些实施例中，冠部可以包覆模制到基座上或附接到基座上，并提供较大和/或更稳定的组织接触表面，用于支撑由钉子捕获的组织。结果，减少了订书钉被拉动通过组织和/或组织在订书钉内或周围撕裂的可能性。

摘要： An anastomotic ring device for forming a hollow rivet (ring) attachment between tissue lumens facilitates laparoscopic or endoscopic implantation by including features that facilitate actuation from a stressed, generally cylindrical shape. Economical manufacturer is achieved by weaving open ended strands into a generally cylindrical stent shape that is imparted with a Shape Memory Effect (SME) to actuate to a hollow rivet (ring) shape. Alternatively or in addition to SME inherent in the woven strands, an actuating force may be received from a helical spring element incorporated into the ring. Self-actuating ring devices are enhanced by forming woven strands into petals that diverge from opposing petals such that the strands encounter less friction when actuating. Each of these features alone or in combination enhance clinical use of anastomotic ring devices, such as a bariatric gastric bypass procedure.
摘要翻译：用于在组织腔之间形成中空铆钉（环）附件的吻合环装置通过包括便于从应力大致圆柱形形状的致动的特征来促进腹腔镜或内窥镜植入。经济的制造商通过将开端线编织成通常具有形状记忆效应（SME）以致动到中空铆钉（环）形状的大致圆柱形支架形状来实现。替代地或除了编织股线固有的SME之外，可以从并入环中的螺旋弹簧元件接收致动力。自动致动环装置通过将编织线形成为从相对的花瓣分开的花瓣而增强，使得在致动时股线遭遇较少的摩擦。这些特征中的每一个单独地或组合地增强了吻合口装置的临床应用，例如减肥胃胃旁路手术。

摘要： A stapler mechanism is described which contains a stapling assembly, and anvil assembly, firing means and knife means. These means are activated by a firing trigger. The anvil assembly is closed upon the stapling assembly by means of a closure trigger. The firing trigger is inoperable until the closure trigger has been activated. Another mechanism in the stapler is capable of locking the closure trigger after use so it does not spring open inadvertently before use of the firing trigger. Additionally, the stapler mechanism allows forward motion of both triggers and also is capable of allowing reverse motion of the closure trigger to open the mechanism.

摘要： A safety-shielded trocar having an obturator with a linear cutting edge surface defining a base width substantially less than the diameter of the safety shield is disclosed. When the trocar is inserted through tissue, the tissue dilates from the width of the linear incision to accommodate the size of the safety shield of the trocar, thus making it possible to provide an access opening greater than the incisional width made by the linear cutting edge surface of the obturator. In a preferred embodiment, the safety shield has a shield tip region which is asymmetric to facilitate the dilation of the tissue as the trocar is inserted.
摘要翻译：公开了一种安全屏蔽套管针，其具有带有线性切割边缘表面的闭塞器，其限定基本宽度基本上小于安全护罩的直径。当套管针穿过组织插入时，组织从线性切口的宽度扩张以适应套针针的安全护罩的尺寸，从而可以提供大于由线性切割边缘形成的切口宽度的进入口闭孔表面。在优选实施例中，安全护罩具有不对称的屏蔽尖端区域，以便在套管针插入时促进组织的扩张。

摘要： A trocar having an obturator with an obturator housing, a piercing tip and a rigid stem is disclosed. The piercing tip has a cutting edge surface and first and second spaced-apart legs generally parallel to each other extending away from the cutting edge surface. The stem is attached to the obturator housing at a first end of the obturator, and the legs of the piercing tip straddle the stem at an opposite end of the obturator. The straddling of the legs about the stem of the obturator fixes the piercing tip to the stem. The attachment of the piercing tip to the stem provides a secure attachment. The trocar is easy to manufacture and assemble, and the component parts can be readily disassembled. The piercing tip attachment is especially advantageous when the piercing tip is configured generally as a razor blade.
摘要翻译：公开了一种具有闭塞器的套管针，其具有闭塞器壳体，穿刺尖端和刚性杆。穿刺尖端具有切割边缘表面，并且第一和第二间隔开的腿大体上彼此平行，远离切削刃表面延伸。所述杆在所述闭孔器的第一端附接到所述闭孔器壳体，并且所述穿刺尖端的腿在所述闭孔器的相对端跨越所述杆。围绕闭孔杆的腿的跨接将穿刺尖固定到杆上。穿刺尖端连接到杆上提供牢固的附件。套管针易于制造和组装，组件可以轻松拆卸。当穿刺尖端通常配置为剃刀刀片时，穿刺尖端附件是特别有利的。
