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.

The invention relates to an arc-shaped cutting anastomat comprising an anastomosis nail shaping mechanism, a nail pushing assembly, a trigger handle, a nail supporting seat, a base of the nail supporting seat, a knife cushioning ring and two splints, wherein the nail pushing assembly comprises a cutting knife, a nail pushing sheet, a nail bin and a guide post; the end of the nail pushing sheet and both sides of the cutting knife are respectively provided with a plurality of inner nail pushing dental sheets which are near the cutting knife and a plurality of outer nail pushing dental sheets which are far away from the cutting knife; the cutting knife and the nail pushing sheet are injected and molded at a time to be fixed together; the outer side of the each outer nail pushing dental sheeton the nail pushing sheet is provided with a reinforcing rib; the inner side of each nail pushing dental sheet on the nail pushing sheet is provided with a reinforcing rib; both ends of the first guide surfaces of the nail pushing dental sheets are respectively connected with the first contact surfaces and the second contact surfaces of the nail pushing dental sheets through concave arc-shaped connecting surfaces, and both ends of the second guide surfaces thereof are respectively connected with the first contact surfaces and the second contact surfaces through the concave arc-shaped connecting surfaces; and the first contact surfaces and the second contact surfaces are respectively in contact with the inner walls of the nail pushing dental sheet holes of the nail bin. The invention has the advantages of good trigger anastomosis shaping effect and high safety.

An expandable spacer, comprising: an axial tube having a surface, a proximal end and a distal end and a length, wherein, said surface defines a plurality of slits, said plurality of slits defining at least two axially displaced extensions, such that when said tube is axially compressed, said extensions extend out of said surface and define a geometry of an expanded spacer. Preferably the spacer is adapted to be inserted between two spinal vertebrae of a human.

Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. The seat comprises an arcuate member comprising a plurality of slits defining a plurality of segment members having a gap there-between. Each of the gaps are variable such that movement of segment members inwardly causes the gaps to be narrowed or closed off completely when a plug element is disposed into the bore and landed on the arcuate member to move the arcuate member from the first position to the second position, causing restriction of fluid flow through the bore and the well conduit.

A control circuit for a lighting system allows analog control over a first range of illumination intensities in which the intensity of the illumination source varies in proportion to the voltage level of the control signal. The circuit provides for improved dimming and color mixing capability by allowing pulse width or frequency modulation control in addition to analog control over a second range of illumination intensities.

An apparatus, method and system are provided for controlling the solid state lighting, such as LEDs. An exemplary apparatus comprises: a switch for switching electrical current through the LEDs, a current sensor; a first comparator adapted to determine when a switch electrical current has reached a first predetermined threshold; a second comparator adapted to determine when the switch electrical current has reached a predetermined average current level; and a controller. The controller is adapted to turn the switch into an on state and an off state, to determine a first on time period as a duration between either a detection of a second predetermined current threshold or the turning the switch into the on state, and the detection of the predetermined average current level; to determine a second on time period as a duration between the detection of the predetermined average current level and the detection of the first predetermined current threshold; and to determine an on time period of the switch as substantially proportional to a sum of the first on time period and the second on time period. Additional exemplary embodiments utilize a difference between the first and second on time periods to generate an error signal to adjust the on time period of the switch.

A rearview mirror system comprises a spotter mirror for providing an image of an object in a vehicle's blind zone to the vehicle's operator. A recognition enhancement device is provided with the spotter mirror for drawing the attention of the driver to the spotter mirror when an overtaking vehicle enters the driver's blind zone. The signaling display is activated by a sensing system which senses the presence of the overtaking vehicle in the blind zone. An electrochromic element is incorporated into the spotter mirror to reduce the intensity of light transmitted from the object and reflected from the spotter mirror. Activation of the electrochromic element to darken the spotter mirror will induce the operator to observe the object in the spotter mirror.
