  • Publication number: 20240157078
    Abstract: The present invention discloses a functional powder delivery device for precise locating and quantifying when delivering the functional powder to a site in need in a patient. Meanwhile, the device avoids negative pressure effect in the output catheter when airflow is switched, and thus prevents pollution or jam in the output catheter due to splash or back flow of body fluid. The device ensures tube clearance of the output catheter by maintaining continuous airflow, and a special design of airflow switch allows switching to airflow of large volume to carry the powder when required. Through continuous positive airflow in the tube system, the functional powder can be delivered to the site in need by a continuous powder flow, which overcomes drawbacks of the delivery devices in prior arts. In addition, the design of foot pedal can help endoscopist for a solo operation. The serial connecting parts can adapt for various size of bottles of various types of functional powder.

  • Publication number: 20160270802
    Abstract: The present invention discloses a guiding element and a guiding assembly for spinal drilling operation. The guiding element is configured to be dispose at a vertebra which comprises a lamina. The guiding element comprises a main body, two connection parts, and two locating parts. The main body has two stand portions and each of the stand portion comprises a clamping part. Each of the connection parts comprises a first end and a second end. The two first ends extends away from each other. Each locating part connects to each stand portion through each connection part. Each clamping part comprises two hook portions. Each side, which is configured to be in contact against the vertebra, of the hook portions has a curvature corresponding to the surface of the lamina, so that the main body is configured to be disposed at the lamina and across the vertebra through the hook portions.

  • Patent number: 8217771
    Abstract: A method and a system of determining the deviation of dynamic position are provided. The determining method includes the follow steps. First, a server receives a plurality of first position data from a first mobile device. Next, the server receives a plurality of second position data from a second mobile device. Then, the server transmits the first position data to the second mobile device. Thereon, the server transmits the second position data to the first mobile device. Later, the server determines whether the first mobile device and the second mobile device deviate from each other according to the first position data and the second position data.
