    摘要： A surgical staple-clip including a clip component and a securing member is used in a wide range of surgical procedures. The staple-clip may be introduced to a surgical site in an un-assembled condition through a small port or trocar. An applier for the staple-clip comprising a pair of opposed jaw-like channels is provided to position and apply the clip component and the securing member. The clip component is positioned around a target tissue and is compressed or clamped upon the tissue using only the force required for a specific surgical procedure such as occlusion, ligation or fixation. When the clip component is properly applied, the securing member is urged forward and over the clip component to secure the staple-clip. The clip component may include traction enhancement features such as surface interruptions, bumps, valleys and ridges. With the staple-clip of the invention, the force required to constrict or occlude the tissue is separate from the force required to secure and maintain the staple-clip in position and, as a result, the body tissue is not over-compressed and nourishment to the body tissue is maintained. Other aspects of the invention include thumb actuated clip appliers for use in hand assisted laparoscopy (HAL) In one embodiment, a clip applier includes a handle and a thumb actuated mechanism that is used to slidably release clips onto a body tissue or vessel by sliding the thumb actuated mechanism forward and backward using only one hand. In another aspect of the invention, a two-stage clip is disclosed having a clip component and a staple component for securing the clip after it has been properly positioned.

    摘要： The invention is directed to a surgical access system that provides access to a surgical area while maintaining pneumoperitoneum during laparoscopic surgery. The access system comprises a sheath retractor adapted to dilate a wound stretchable to a desired diameter and a detachable seal adapted to be removable from the sheath retractor. In another aspect, the detachable seal comprising a valve including a plurality of overlapping sheets defining an access channel that extends into communication with the incision in the patient. Each of the overlapping sheets includes a portion of the perimeter that is not fixed to the inner diameter of the ring, which provide open edges defining the access channel.

    摘要： A steerable kink resistant access device is provided having an elongated body and a steerable portion; methods for manufacturing the kink resistant device are also provided. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.

    摘要： An insufflation gas warmer and humidifier apparatus and methods are provided. Insufflation gas is received from a bulky insufflation tubing. Insufflation gas received travels through, in one aspect, a channel or winding flow path, in a passage. The configuration of the passage ensures that the insufflation gas, which travels through the passage, receives sufficient heat and moisture. A humidifying reservoir humidifies the insufflation gas as the insufflation gas is passed to the passage. In one aspect, an oxygenator introduces slight amounts of oxygen into the insufflation gas. A warmer connected to the passage warms the gas in the passage. The warmer, in one aspect, contains a reactive agent that when exposed to air produces heat that is transferred to the passage to warm the insufflation gas within the passage.
