Overmolded grasper jaw

ActiveUS7494501B2Facilitate closing the jaw spinesEnhanced advantageSurgical forcepsPlastic materialsMetallic materials
The invention is directed to a surgical instrument comprising an elongate tube extending along an axis including a camming rod and an actuation mechanism operably connected to the camming rod, the camming rod having a camming pin and a camming projection; a first jaw spine having a first cam slot, a first interior camming surface, and a first exterior camming surface; and a second jaw spine having a second cam slot, a second interior camming surface, and a second exterior camming surface, the second jaw spine pivotally connected to the first jaw spine at a common pivot pin operably connected to the elongate tube to open and close the jaw spines in response to movement of the actuation mechanism. The camming pin rides along the first and second interior camming surfaces and operates to close the jaw spines when the camming rod is moved proximally. When the camming rod moves distally, the camming projection rides on the first and second exterior camming surfaces formed on the proximal sides of the respective first and second jaw spines and operates to open the jaw spines. A feature of the invention is one camming surface on each jaw spine can facilitate closing the jaw spines while the other camming surface on each jaw spine can facilitate opening the jaw spines. These two camming surfaces on each jaw spine can be widely separated. The jaw spines can be formed of a metallic material and are overmolded with an atraumatic plastic material. By overmolding the plastic onto the metal spine, an atraumatic outer surface can be formed of the plastic material along with a high degree of detail.

Semiconductor device and method for manufacturing the same

A thin film transistor structure in which a source electrode and a drain electrode formed from a metal material are in direct contact with an oxide semiconductor film may lead to high contact resistance. One cause of high contact resistance is that a Schottky junction is formed at a contact plane between the source and drain electrodes and the oxide semiconductor film. An oxygen-deficient oxide semiconductor layer which includes crystal grains with a size of 1 nm to 10 nm and has a higher carrier concentration than the oxide semiconductor film serving as a channel formation region is provided between the oxide semiconductor film and the source and drain electrodes.

Polymer link hybrid stent

InactiveUS7455687B2Improve column strengthHigh strengthStentsSurgeryCoronary arteriesMetallic materials
The present invention is directed to an expandable polymer link hybrid stent for implantation in a body lumen, such as a coronary artery along with a method of making the stent. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of polymeric links. The polymer links are formed by applying polymer layers between the rings and laser ablating the excess material. The polymeric material forming the polymeric links, provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis. The metallic material forming the rings provides the necessary radial stiffness.

Selective etch of silicon by way of metastable hydrogen termination

Methods of etching exposed silicon on patterned heterogeneous structures is described and includes a remote plasma etch formed from a fluorine-containing precursor and a hydrogen-containing precursor. Plasma effluents from the remote plasma are flowed into a substrate processing region where the plasma effluents react with the exposed regions of silicon. The plasmas effluents react with the patterned heterogeneous structures to selectively remove silicon while very slowly removing other exposed materials. The silicon selectivity results, in part, from a preponderance of hydrogen-containing precursor in the remote plasma which hydrogen terminates surfaces on the patterned heterogeneous structures. A much lower flow of the fluorine-containing precursor progressively substitutes fluorine for hydrogen on the hydrogen-terminated silicon thereby selectively removing silicon from exposed regions of silicon. The methods may be used to selectively remove silicon far faster than silicon oxide, silicon nitride and a variety of metal-containing materials.
