    • A surgical trocar has a cannula assembly including a sleeve having a proximal end, a distal end and a passageway therethrough. A housing having an opening is located at the proximal end of the sleeve and is aligned with the passageway of the sleeve. The trocar also includes an obturator assembly which is insertable in the cannula assembly. The obturator assembly includes a handle and an obturator shaft. The obturator shaft has a proximal end connected to the handle and a distal end opposite the proximal end. A penetrating tip is located at the shaft distal end for penetrating tissue. A protector having a distal end is slidably disposed around the obturator shaft for covering the penetrating tip. The protector has an aperture at its distal end for permitting the penetrating tip to pass therethrough. The protector also includes a flexible proximal end movable against the obturator handle to expose the penetrating tip when a proximal force is asserted against the protector. A seal assembly is located in the housing for sealing against the obturator assembly or surgical instruments passed through the cannula assembly. The seal assembly includes an upper seal arrangement having an aperture. The seal assembly also includes a pressure seal located beneath the upper seal arrangement. The pressure seal includes a pair of side walls. At least one rib is located on the inner surface of each side wall.

    • A method for establishing a surgical port for endoscopic or arthroscopic surgery is disclosed. A trocar is initially provided, and the obturator of the trocar includes a flat cutting blade, a shield that moves proximally and distally from a precock position to an extended position, a precock lever to move the shield proximally to expose the flat cutting blade, and a shield retaining assembly to constrain the shield in the proximal position. "Precocking" the trocar of the present invention moves the shield from the distal position wherein the flat blade is covered, to a proximal position wherein the flat blade is exposed, and the shield is constrained by the shield retaining assembly. Once the flat cutting blade is exposed, the skin of the patient is incised with the flat cutting blade of the obturator. The flat blade of the trocar is inserted into the incision and a penetrating force is applied so that the flat blade penetrates into the internal body cavity of the patient. The obturator assembly is removed from the cannula assembly so that the surgical access port is provided into the internal body cavity of the patient. This method eliminates the need for a separate surgical sharp to initially incise the skin before penetration is effected.
    • 公开了一种建立内窥镜或关节镜手术的手术口的方法。 套管针最初设有套管针,套管针的封闭器包括一个平切割刀片,一个护板,其近端和远端从一个预制座位移动到一个延伸位置;一个防护杆,用于向近侧移动护罩以露出平切刀; 屏蔽保持组件,以在近侧位置限制屏蔽。 本发明的套管针的“预敷”将屏蔽件从扁平刀片被覆盖的远端位置移动到平坦刀片暴露的近侧位置,并且屏蔽件被屏蔽保持组件约束。 一旦平面切割刀片被暴露,患者的皮肤就会被闭塞器的平面切割刀片切开。 将套针针的扁平刀片插入切口中,并施加穿透力,使得扁平刀片穿透患者体内腔体。 将闭塞器组件从套管组件移除,使得外科进入口被提供到患者的内部体腔中。 该方法不需要单独的外科手术,以便在穿透之前最初切开皮肤。

    • A linear surgical stapler adapted for applying a plurality of surgical fasteners to body tissue includes an anvil structure and a cartridge housing containing a plurality of surgical fasteners. The cartridge housing and anvil structure are relatively movable between a first spaced apart position and a second position in close approximation with one another. A firing mechanism is associated with the cartridge housing for ejecting the surgical fasteners from the cartridge housing to be driven against the anvil structure. A lockout mechanism interacts with the cartridge housing for selective activation and deactivation. The lockout mechanism includes a swing gate tab secured to the cartridge housing at a position adjacent a lockout lever, such that firing of the linear surgical stapler rotates the swing gate tab releasing the lockout lever for preventing further firing of the used cartridge housing.
    • 适于将多个手术紧固件应用于身体组织的线性手术吻合器包括砧结构和容纳多个手术紧固件的药筒外壳。 盒壳体和砧座结构在第一间隔开的位置和彼此近似近似的第二位置之间可相对移动。 击发机构与药筒外壳相关联,用于将外科紧固件从药筒外壳排出以抵靠砧座结构被驱动。 锁定机构与盒壳体相互作用以选择性地激活和去激活。 锁定机构包括在邻近锁定杆的位置处固定到盒壳体的摆动闸板突出部,使得线性手术吻合器的点火使摆动闸板拉片旋转以释放锁定杆,以防止进一步对已使用的盒壳体进行点火。
