摘要： A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one embodiment, a surgical clip applier is provided and can include a shaft having a proximal end and a distal end with opposed jaws thereon, a guide member disposed within the shaft and configured to guide a clip into the opposed jaws, the guide member having a channel formed in a surface thereof, and an advancer movably disposed within the shaft and configured to advance a clip over the guide member and into the opposed jaws, the advancer having a distal tip that slidably engages the channel for maintaining contact with a surgical clip as it is advanced into the opposed jaws. In other embodiments, the guide member can also include a proximal channel formed in a superior surface thereof. The advancer can be configured to deflect downward into the proximal channel to move proximally beneath an inferior surface of the apex of the clip to position itself proximally to the clip to advance the clip into the opposed jaws.

摘要： A laparoscopic surgical access device comprises a first frame and a second frame having relative axial positions. A flexible and resilient iris valve is connected to the first and second frames and has a closed position and an opened position based on the relative angular position of the first and second frames. A lock is connected to the first and second frames, the lock being selectively operative to prevent relative rotational movement in a first rotational direction. One embodiment uses a ratchet and pawl mechanism operable with a control ring. Another embodiment uses a ratchet and pawl mechanism operable with a button. Yet another embodiment uses a wedge track and ball mechanism.

摘要： A method is provided for removing at least one tissue sample from a surgical patient using a biopsy instrument. The biopsy instrument comprises an elongated piercer having a piercer lumen extending therethrough. The biopsy instrument further comprises a cutter rotatably and translationally positionable relative to the piercer. The piercer has a port for receiving and transferring the tissue portion into the piercer lumen. In one embodiment of the present invention, the method for using the biopsy instrument comprises the steps of engaging tissue in the port; translating the cutter at a first, predetermined translational speed from a first position to a second position proximal to the port; measuring the translational speed of the cutter; translating the cutter at a second, predetermined translational speed from the second position to a third position proximal to the port; translating the cutter at a third, predetermined translational speed from the third position to a fourth position distal to the port; rotating the cutter at a predetermined rotation speed; measuring the rotational speed of the cutter; and modifying the translational speed of the cutter when the rotational speed of the cutter varies from the predetermined rotational speed by more than a first, predetermined differential rotational speed.

摘要： The present invention is a control apparatus for removing at least one tissue sample from a surgical patient using a surgical biopsy device. The biopsy device comprises an elongated piercer having a piercer lumen extending therethrough, and a cutter rotatably and axially positionable relative to the piercer. The piercer has a port for receiving and transferring the tissue sample into the piercer lumen. The biopsy device further comprises a rotation motor for rotating the cutter and a translation motor for translating the cutter in the axial direction. In one embodiment of the present invention, the control apparatus comprises a computing device for the coordinated control of the rotation and translation motors. The control apparatus further comprises a first sensor operationally connected to the rotation motor for supplying a rotation signal to the computing device for measuring the rotational speed of the cutter. The control apparatus further comprises a second sensor operationally connected to the translation motor for supplying a translation signal to the computing device for measuring the translational position and translational speed of the cutter. The control apparatus further comprises a first driver for driving the translation motor in response to a translation command from the computing device, and a second driver for driving the rotation motor in response to a rotation command from the computing device. The control apparatus automatically modifies the rotational speed and the translational speed of the cutter in response to the translational position and rotational resistance acting on the cutter.
