    摘要： A hypodermic syringe includes a barrel with a plunger slidably extending therein. The barrel may include a barrel adapter at one end to define a luer hub socket and the outer walls of slots in the barrel. The plunger includes an outer plunger element and an inner plunger element telescoping together with a bungee resisting extension of the assembly. The inner and outer plunger elements may be locked in the extended position with the bungee in tension. A seal stop is located at the seal end of the plunger to define an annular pinch therewith to hold an annular seal in radial extension sealing against the internal sidewall of the barrel. A luer hub is fixed at the needle end of the barrel, A plunger cap may be advanced after injection to rotate the plunger. A resistance lock retains the cap and plunger indexed until actuation. The rotation actuates latches and locking fingers on the luer hub to engage a probe axially and rotationally on the seal end of the plunger and disengage the slots in the barrel, respectively. The rotation disengages the seal stop to release the annular seal and finally releases the engagement between the outer plunger element and inner plunger element. The foregoing provides for the retraction of the luer hub and associated needle into the barrel.

    摘要： An apparatus is operable to secure suture fasteners to sutures to eliminate the need to tie knots in the sutures. The apparatus comprises a shaft, an end effector disposed at the distal end of the shaft, and a suture fastener removably secured to the end effector. The end effector may include a pivoting jaw or a suture cutter. The suture fastener may be secured to one, two, or more strands of suture. The apparatus may include several suture fasteners and may secure those fasteners to one or more sutures in a serial fashion without having to remove the apparatus from the patient for reloading. A plurality of fasteners may be arranged within the apparatus in an end-to-end configuration. The suture fastener may include an inner fastener member and an outer fastener member, and may capture one or more strands of suture between the inner and outer fastener members.

    摘要： A needle holder includes a shaft and a needle driver located at the distal end of the shaft. The needle driver is operable to rotate a needle such that the needle forms a non-perpendicular angle with a longitudinal axis of the shaft. In some versions, the needle driver includes a first arm and a rotatable assembly that is configured to longitudinally clamp about a portion of a needle. The rotatable assembly may include self-righting features to right the needle perpendicular to the first arm. The needle driver may further include a second arm that is pivotable relative to the first arm. The rotatable assembly may include a top member associated with the second arm and a bottom member associated with the first arm. In some versions, spring-loaded collets may secure the needle to a rotatable assembly. Alternatively, a pair of actuating arms may pivot the needle about a curved surface.

    摘要： A suture needle driving instrument comprises a shaft, an end effector, and a grasping actuation assembly. The end effector is located at the distal end of the shaft and includes a pair of grasping arms. Each grasping arm comprises a respective pair of jaws. Each pair of jaws is operable to cooperate to grasp and release a suture needle. The grasping actuation assembly is operable to drive one jaw of each pair in one direction while simultaneously driving the other jaw of the pair in an opposite direction, to selectively grasp or release the suture needle. The actuation assembly may include a drive shaft having separate threaded regions with opposing pitch. The end effector is further operable to pass the needle from one arm to the other arm during a suturing procedure. The instrument may be used through a trocar during minimally invasive surgery.
