The present invention provides a rotatable stapling head of a surgical stapler, which comprises a staple cartridge (1), a staple driver (2), a scalpel (3), a compression rod (4), a staple casing (5) and a rotating assembly. The above parts constitute a rotating forward mechanism which can rotatablely forward the scalpel therein.

An operating staple is provided in which stability during an operation is enhanced by firmly suturing an operating portion and an intraluminal stapeler for operation having the operating staple. The operating staple closely sutures a first suturing tissue and a second suturing tissue contacting the first suturing tissue, and the operating staple includes: a center portion extending in close contact with a surface of the first suturingtissue; a pair of penetrating portions which is bent from both ends of the center portion and penetrates the first suturing tissue and the second suturing tissue; and a pair of leg portions which is bent from the respective penetrating portions, extends linearly, and closely bonds the first suturing tissue and the second suturing tissue to each other. Therefore, by utilizing the operating staple, the suturing tissues can be firmly sutured, thereby enhancing the stability during an operation.

The invention discloses and belongs to the chemical equipment field, which more particularly relates to a C1-C2 hydrocarbon or methanol aromatization and catalyst regeneration fluidized bed device (comprising an aromatization fluidized bed, a catalyst continuous regeneration fluidized bed, a pipeline used for catalyst transportation and a solid transportation device which are arranged between the two fluidized beds), and an aromatization catalyst which is suitable for the fluidized bed operations and the operation methods of aromatization reaction, catalyst regeneration and the device. The device, the catalyst and the method are used for regulating the coking status of the catalyst in an aromatization reactor at any time, thus achieving the aim of transforming the C1-C2 hydrocarbon or the methanol continuously and efficiently and generating aromatics with high selectivity. The C1-C2 hydrocarbon or methanol aromatization and catalyst regeneration fluidized bed device of the invention with adjustable catalyst activity and selectivity can improve the purity and yield of the aromatics, can lead the aromatization reactor operates continuously without stopping at the same time, can improve the strength of aromatics production, and lower the operation cost of the catalyst regeneration when stopping and restarting the whole system.

An output from a generator section is controlled by a current converter section to be a constant current. Charging and discharging of a power storage section is controlled by a charge / discharge control circuit. Thereby, even in a case where a current value required by a load is high, the case can be dealt with in the manner that, while an output current from the generator section is being maintained constant, the output from the generator section and an output from the power storage section can be caused to function in cooperation with each other. Further, charging and discharging of the power storage section can be performed by a simplified device.

A method for establishing uplink synchronization in a base station, according to one embodiment of the present description, comprises performing a process for connection to user equipment, setting component carrier aggregation information, generating uplink timing groups from the set component carrier aggregation, and transmitting, via a plurality of component carriers, information on the thus-generated uplink timing groups simultaneously to the user equipment.

Uplink synchronization establishment in a base station which operates a plurality of component carriers according to one embodiment of the present description, is performed in that the base station is connected to a user equipment, sets component carrier aggregation information, generates an uplink timing groups in the set component carrier aggregation, and transmits information on the thus-generated uplink timing groups to the user equipment.

A system for the percutaneous stabilization of adjacent vertebrae includes a plurality of elongated stabilization devices. Each stabilization device includes a radius of curvature. Each stabilization device further includes a leading end and a trailing end wherein the leading end is pointed for penetration through a vertebral body.

A lifter is provided on a drum for lifting and dropping laundry in the drum during a rotation of the drum. The lifter slides and moves along an inner surface of the drum after passing through the inner surface so as to be engaged to the drum. At least one slot is provided on a circumference of the drum, and at least one hook is provided on the lifter for being engaged to the slot. Further, at least one projection is provided on the drum, and at least on rib is provided on the lifter. The projection and the rib are tightly engaged with each other so as to secure the lifter to the drum when the lifter completely slides and moves laterally.

An exercise device is provided including a foot link having a rearward end and a forward end. An adjustable stride mechanism is provided. The adjustable stride mechanism includes a primary gear and a secondary gear. The primary gear is sized larger relative to the secondary gear. A primary crank connects the primary gear and the secondary gear. A timing belt connects the primary gear to the secondary gear. The primary crank and the timing belt enable the secondary gear to rotate around the primary gear. A secondary crank is pivotally attached to the secondary gear and to a foot link. The secondary crank creates an ellipse-shaped path for the foot link as the secondary gear rotates around the primary gear. Thus, the foot link motion combines an at least a dual ellipse motion. An automatic adjusting mechanism can be provided to adjust the adjustable stride mechanism.

An improved, durable and versatile umbrella frame assembly is provided to more readily endure abusive weather conditions and that may be quickly, easily and inexpensively repaired. In addition, the assembly is also easily modified to accommodate umbrella canopies of different sizes and shapes. In addition, an improved umbrella operating system is provided to permit simple opening, positioning, and locking of an umbrella while allowing the frame to freely rotate about the pole regardless of the degree to which it is opened, while the pole is held in a stationary position. The assembly includes a pair of hub members mounted about a pole member wherein the main hub member is slidable up and down the pole. A pulley system with a locking cam member may be employed to allow the umbrella to safely and easily open to any desired position. A locking stabilizer arm may be used to secure the main hub member in the fully open position.

Disclosed embodiments describe a volar plate generally for use treating distal volar fractures. The volar plate is designed in accordance with anatomical features and is generally Y-shaped, having a wider distal head portion that tapers to a narrower proximal body portion. A plurality of holes in the distal head of the volar plate allow for fixation means to fix the position of bone fragments with respect to the volar plate. The plurality of holes in the distal head basically form two substantially non-linear rows, with the distal row generally curving inward proximally and the proximal row generally curving outward distally such that the fixation means inserted through the holes generally converge. A central cavity may be located in the proximal body of the volar plate to promote bone growth, and mounting screws may border the central cavity on either side to provide secure support. Additionally, K-wire holes may be included which are visually linked to corresponding holes in the distal head.

Disclosed is a portable net device comprising a main member forming a first closed loop, a base member forming a second closed loop and defined by front and non-front sections where a main member bottom section is attached to the base member front section, a fabric member having front and non-front sections where the fabric member front section is connected to the main member, a connecting member to selectively attach the fabric member non-front section to the base member non-front section in a detachable attachment format, and a supporting member to sustain the main member against the base member while maintaining a substantial angle between the main and base members.
