  • Publication number: 20250099129
    Abstract: A resection apparatus includes a handle body, a catheter communicating with the handle body, and a cutter head assembly disposed at a distal end of the catheter. A steering assembly is disposed on the catheter and includes a first steering point and a second steering point which are disposed on the catheter, and a steering connector for connecting the first steering point and the second steering point. A control assembly for controlling the steering assembly is disposed on the handle body. The bending radius of the catheter at the distal end is adjusted by means of the steering assembly, so that the catheter is shifted towards a predetermined direction; the orientation of the cutter head assembly is controlled, so as to reduce a risk of scraping and perforating a blood vessel, and the ideal blood vessel diameter can be obtained by means of multiple resections.

  • Patent number: 11008081
    Abstract: An underwater drone is disclosed. The underwater drone includes a horizontal propeller module and a vertical propeller module to respectively provide a drone body with a horizontal proceeding force and a vertical lifting or diving force. The underwater drone includes a horizontal channel and a vertical channel, which allow the water to pass through for reducing resistance when the underwater drone moves forwards, upwards or downwards. The underwater drone is equipped with a buoy member with an antenna portion of a communication module disposed therein. The underwater drone is equipped with the fishing device, the fish finding device and the image capturing module. Therefore, the underwater drone is capable of fishing, rapidly moving and wireless remote control.

  • Publication number: 20160063024
    Abstract: A network storage deduplicating method and a server using the same method are proposed. The method includes the following steps: receiving a first data through an Internet small computer system interface protocol; calculating identification information of the first data; determining whether a second data having the identification information is already stored in the server; if yes, generating and storing a pointer pointing to the second data and neglecting the first data.

  • Publication number: 20110091482
    Abstract: The present invention is based on the finding that the level of KIR expression in a cancer cell is significant with regard to tumor invasion and metastasis. Therefore, the present invention concerns methods and compositions for evaluating cancer in a patient based on KIR protein or mRNA expression. The invention also provides methods and compositions for treating cancer using a KIR inhibitor and methods of screening for KIR inhibitors.
