  • Publication number: 20170354403
    Abstract: A surgical instrument with pressure sensing and vision feedback functions has an instrument body and a piezochromic device. The instrument body includes a work piece with a visible surface. The piezochromic device is disposed on the visible surface of the work piece of the instrument body and performs color change when the piezochromic device senses pressure. Therefore, when a doctor performs surgery using the surgical instrument, the doctor can directly see the piezochromic device. When the piezochromic device contacts other surgical instruments or presses organs or tissues within a patient's body, the piezochromic device will change color when the piezochromic device senses the pressure enabling the doctor to adjust the surgical instrument accordingly.

    Abstract: An adjustable light source device for a stereoscopic surgical microscope has a circuit board and multiple light sources. The circuit board is mounted in an outer casing of the stereoscopic surgical microscope and is electrically connected to a host computer of the stereoscopic surgical microscope. The light sources are electrically mounted on the circuit board at spaced intervals around two objective lenses of the stereoscopic surgical microscope and extend out of the outer casing. Each one of the light sources has a wavelength different from wavelengths of the other light sources and is controlled to emit light by an operating set of the stereoscopic surgical microscope via a program processing interface of the host computer sending signals to the circuit board. The adjustable light source device can emit lights with different wavelengths to enable the stereoscopic surgical microscope to capture clearer images for various surgical divisions.

  • Publication number: 20090038924
    Abstract: An automatic timing switch device includes a switch control wheel, a driving assembly, and a plurality of push switches. The switch control wheel includes a plurality of wheel-shaped structures stacked sequentially, wherein each of the wheel-shaped structures has at least one notch formed on an outer periphery of the switch control wheel, and the diameters of the wheel-shaped structures reduce sequentially so that the switch control wheel is in tapered shape. The driving assembly drives the switch control wheel to rotate. The push switches are switched by engaging into or separating from the notches of the wheel-shaped structures as the switch control wheel rotated by the driving assembly. Since the switch control wheel is in a tapered shape, so that the switch control wheel is easily to be formed monolithically and is convenient to be installed to the case of the automatic timing switch device.

  • Patent number: 6727440
    Abstract: An electromechanical program timer provides at least a section with a slower timing speed besides a major timing speed. The timer includes a driving motor rotationally drives a driving shaft. A driving gear and an eccentric shaft are formed on the driving shaft for driving a cam disk through a main driven gear and via a pushing pawl to a driven ratchet respectively. The main driven gear includes at least a missing gear portion where the driving gear is free from driving the main driven gear, and the pushing pawl and the driven ratchet take place. The driving shaft engages and rotates the cam disk through the main driven gear in a major timing speed. While at the missing gear portion, the eccentric shaft oscillates the pushing pawl and drives the cam disk through the driven ratchet step by step in a reduced timing speed.
