    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.

    摘要： A surgical access port for insertion into a body cavity can have an elongate tubular body extending along an axis between a proximal end and a distal end, and a tip at the distal end of the tubular body for penetrating through a body wall and into the body cavity. The distal tip moves from a first, penetrating position to a second, retaining position when the body wall has been traversed. The surgical access port may further comprise a seal housing connected to the proximal end of the tubular body, the seal housing having an access port providing an opening into the tubular body to allow passage of surgical instruments. The distal tip may be sharp, pointed or bladed. The distal tip may also be substantially blunt or have a conical surface. The access port may further comprise a retention member for connecting the tubular body and the distal tip.

    摘要： A surgical access device adapted for disposition relative to an incision in a patient comprising a valve including a plurality of overlapping sheets defining an access channel, and a ring having an inner diameter for holding the valve by fixing each of the overlapping sheets along a portion of the perimeter is described. The access channel 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. The open edges slightly overlap at the center of the ring.

    摘要： A surgical access device, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.

    摘要翻译： 手术进入装置，例如套管针，包括具有从近端延伸到设置在远端的隔膜阀的细长结构的侧悬阀。 在操作中，细长结构遵循仪器的角度，以将隔膜阀预先定位到仪器的路径中，在仪器插入或操纵期间，隔膜阀不会受到严重的挑战。 悬挂阀可以制成在细长结构的近端和远端两侧浮动，以进一步降低隔膜阀的脆弱性。 由于阀门不易受仪器插入的影响，因此可以形成最小化摩擦力并最大化进入设备的功能范围。
