A TFT includes a zinc oxide (ZnO)-based channel layer having a plurality of semiconductor layers. An uppermost of the plurality of semiconductor layers has a Zn concentration less than that of a lower semiconductor layer to suppress an oxygen vacancy due to plasma. The uppermost semiconductor layer of the channel layer also has a tin (Sn) oxide, a chloride, a fluoride, or the like, which has a relatively stable bonding energy against plasma. The uppermost semiconductor layer is relatively strong against plasma shock and less decomposed when being exposed to plasma, thereby suppressing an increase in carrier concentration.

The invention relates to a binding mechanism of a surgical binding apparatus, which is placed at the head of the surgical binding apparatus and includes a nail pin, a nail pushing plate and a nail block. The nail pushing plate and the nail pin are installed inside the binding apparatus body. The positions of the nail block and the nail pushing plate are opposite. The invention is characterized in that the working faces of nail pin, the nail pushing plate and the nail block are not at the same plane and at least present a step-type fall distributed structure. When the structure is adopted to form an anastomoses opening, the distance between two lines of nails is enlarged; the elasticity of the anastomoses opening which is formed in the operation is increased and is more close to the physiological characteristic of the tissue, which is in favor of the prompt recovery of the tissue. When the nail block is set out from an anastomoses ring or a content object is put through the anastomoses ring after binding, the elasticity of the anastomoses ring becomes larger to allow the nail block or the content object pass through and reduce the probability of damaging the anastomoses ring.

An apparatus and method for controlling a robot may scale a motion of a surgical robot based on a type of object gripped by the surgical robot. In the robot controlling method, by scaling the motion of the surgical robot based on the type of object gripped by the surgical robot, the surgical robot may automatically perform the motion on objects using an optimized force although a user does not control a force minutely based on the type of object gripped by the surgical robot.

The invention relates to a tubular shaft instrument for separating tissue. In conventional tubular shaft instruments the clean separation of tissue poses a problem. In practice, it is often the case that e.g. as a result of wear to the blade, the tissue is severed by the active force rather than by the action of the blade. The cut edges are also deformed accordingly. The invention relates to a tubular shaft instrument that guarantees a significantly more reliable, cleaner separation of tissue. To achieve this, in contrast to conventional cutting devices, the blade is not displaced through the fixed tissue, but glides over the latter until a complete separation is determined.

Abstract of Disclosure The present invention provides methods and compositions for attenuating expression of a target gene in vivo. In general, the method includes administering RNAi constructs (such as small-interfering RNAs (i.e., siRNAs) that are targeted to particular mRNA sequences, or nucleic acid material that can produce siRNAs in a cell), in an amount sufficient to attenuate expression of a target gene by an RNA interference mechanism, e.g., in a sequence-dependent, PKR-independent manner. In particular, the subject method can be used to alter the growth, survival or differentiation of cells for therapeutic and cosmetic purposes.

A stentless support structure capable of being at least partly assembled in situ. The support structure comprises a braided tube that is very flexible and, when elongated, becomes very long and very small in diameter, thereby being capable of placement within a small diameter catheter. The support structure is preferably constructed of one or more thin strands of a super-elastic or shape memory material such as Nitinol. When released from the catheter, the support structure folds itself into a longitudinally compact configuration. The support structure thus gains significant strength as the number of folds increase. This radial strength obviates the need for a support stent. The support structure may include attachment points for a prosthetic valve.

Not only a plurality of the substrates are disposed on a substrate holder, which is disposed in a film-forming furnace and is connected with a negative electrode, in such a state that they face to each other, but also a processing gas pressure and a plasma power source are operated so as to overlap negative glows of the neighboring two substrates.

An improved surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector has different operations, including grasping, cutting, and sealing and / or coagulating tissue, and one of the operations is controlled by a drive handle mechanism. The drive handle mechanism includes an actuator, a drive shaft and a spring assembly for transferring movement of the actuator to the drive shaft, which in turn controls the end effector. The drive handle mechanism limits the amount of force transferred from the drive handle mechanism to the end effector, preventing damage to the tissue. As the actuator is operated, the spring assembly transfers the movement of the actuator to the drive shaft and the end effector. At the same time, the spring assembly compresses to absorb some of the force applied. Such configuration prevents the tissue being unintentionally damaged by the end effector.

In one aspect the invention provides a method for laser induced breakdown of a material with a pulsed laser beam where the material is characterized by a relationship of fluence breakdown threshold (Fth) versus laser beam pulse width (T) that exhibits an abrupt, rapid, and distinct change or at least a clearly detectable and distinct change in slope at a predetermined laser pulse width value. The method comprises generating a beam of laser pulses in which each pulse has a pulse width equal to or less than the predetermined laser pulse width value. The beam is focused to a point at or beneath the surface of a material where laser induced breakdown is desired.The beam may be used in combination with a mask in the beam path. The beam or mask may be moved in the x, y, and Z directions to produce desired features. The technique can produce features smaller than the spot size and Rayleigh range due to enhanced damage threshold accuracy in the short pulse regime.
