Automatic purse-string device
The invention provides an automatic purse-string device, which comprises an upper shell and a lower shell, and nail warehouse components arranged inside of the shells, wherein the nail warehouse components comprise a nail warehouse, a nail pushing piece and a nail arranged in the nail warehouse. When in an initial state, one end of the upper shell and one end of the lower shell are in pivot connection and are arranged in an angle; and when in the process of working, the upper shell rotates relative to the lower shell, and the upper shell and the lower shell move relative to make the nail pushing piece push the nail out of the nail warehouse after the upper shell is parallel to the lower shell. The automatic purse-string device has the main advantages that the device is compact in appearance, can be packaged and sold serving as an attachment of other surgical instruments, saves material cost, can reduce the economic burden of a patient, and can satisfy the use in a smaller surgical space, thereby enlarging use range and providing a doctor with convenience.

Methods and devices for charge management for three-dimensional sensing
InactiveUS6906793B2Minimal overheadEffective coloringTelevision system detailsOptical rangefindersCMOSHigh frequency modulation
Structures and methods for three-dimensional image sensing using high frequency modulation includes CMOS-implementable sensor structures using differential charge transfer, including such sensors enabling rapid horizontal and slower vertical dimension local charge collection. Wavelength response of such sensors can be altered dynamically by varying gate potentials. Methods for producing such sensor structures on conventional CMOS fabrication facilities include use of “rich” instructions to command the fabrication process to optimize image sensor rather than digital or analog ICs. One detector structure has closely spaced-apart, elongated finger-like structures that rapidly collect charge in the spaced-apart direction and then move collected charge less rapidly in the elongated direction. Detector response is substantially independent of the collection rate in the elongated direction.

A light transmission system to provide photodynamic treatment to a patient includes a single use integrated control module and catheter assembly having a plurality of light emitting diodes (LEDs) to transmit light toward target cells within a patient. The integrated light catheter and control module are used in combination with a light activated drug. Selected operating parameters may be programmed into the control module, or it may be wirelessly programmable in situ prior to use to allow user flexibility to tailor treatment for a particular patient or condition. Among the features that prevent reuse are that the control module lacks access to recharge the power source, and it may include a deactivation module that destroys circuitry or software when triggered. To prevent patient interference when in use, the control module may also be configured to selectively deactivate.
