    摘要： The present invention relates to a surgical access port for insertion into a body cavity having an elongate tubular body extending along an axis between a proximal end and a distal end, and a tip disposed at the distal end of the tubular body for penetrating through a body wall and into the body cavity. The distal tip operates to move 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 operably 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. The retention member may be biased to hold the distal tip in an off-axis position when there is no axial load, or it may be lightly held in axial alignment and subsequently deflected in the presence of an instrument within the tubular body. The distal tip, which may comprise one or more parts or petals, may reposition to the side of the tubular body in a substantially right-angled condition in the second, retaining position. The repositioned tip remains in an off-axis condition until removal of the access port, at which time the distal tip automatically realigns with the axis of the tubular body as the access port is withdrawn from the body wall. The tubular body may be a thin walled tube. The distal tip may comprise a conical, tapered or rounded shape to separate tissue layers. The distal tip may be solid or hollow, which may act as a specimen bag by closing on a specimen and pulled inside the tip during removal of the access port. The distal tip may be formed from a clear material to allow viewing through an endoscope during placement of the surgical access port.

    摘要： The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may be formed of a thermoplastic or a thermoset material. The ring-shaped elements may include plastic rings, metallic rings, un-reinforced plastic rings and/or metal reinforced plastic rings assembled along the length of the tubular structure to provide variable flexibility and kink-resistance. The tubular structure may have a cross-section of any geometric shape and it may be bent, twisted or curved without kinking. The ring-shaped elements may have different flexural modulus. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. The ring-shaped elements may be metallic and may be bonded with a resilient, flexible elastomeric adhesive, wherein the ring-shaped elements may have different lengths and may be fused closer or further apart to one another depending on the characteristics of a portion or section of the tubing. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. The ring-shaped elements may be truncated to provide a bending bias. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure. In yet another aspect of the invention, some of the ring-shaped elements may be radiopaque, or the ring-shaped elements may comprise of different colors to operate as indicators along the tubular structure.

    摘要： The invention is directed to a pair of laparoscopic scissors, comprising a pair of blades connected at a pivot, each of the blades having a length, a tip portion, a body portion, an outer surface, an inner surface and a cutting edge, the cutting edge forming an angle with the outer surface along the length of the blade such that tension during a cutting operation at the tip portion is about the same as tension at the body portion during the cutting operation. The angle formed may be greater at the tip portion which continuously decreases over the length of the blade. The tip portion may have a first body thickness and the body portion may have a second body thickness different from the first body thickness. During the cutting operation, the blades progressively move over each other to provide a point contact along the cutting edges. The blades may be thickened in a number of locations and combinations including: (1) one blade could be thicker than the other to force the opposing blade to flex; (2) both blades could be thicker at the body portions to give more strength when cutting staples; (3) each blade could be thickened on one side or the other to stiffen certain locations; and (4) the tips of each blade could be thicker than the body portions to provide increased tension at the tips. In another aspect of the invention, a process of manufacturing the pair of scissors of the invention is disclosed, comprising the steps of form grinding the blades into a desired shape from a pre-hardened block of material, and sharpening the cutting edges of the blades. The blades may also be formed through other processes including wire EDM, laser cutting, waterjet cutting, machining, cast or metal injection molding, and other independent profile manufacturing processes. The manufacturing process of the invention is beneficial in that each profile can be accurately controlled, and the parts will be exact every time.

    摘要： A method and apparatus is provided for providing a fine delay by switching on a capacitor delay. A coarse delay and/or a fine delay are implemented upon a reference signal based upon a phase shift between the reference signal and a feedback signal. A fine delay is implemented upon the reference signal based upon a phase shift between the reference signal and a feedback signal. Providing the fine delay includes switching on a capacitive delay. A synchronized output signal is generated based upon the fine delay.
