Publication number: 20240389838Abstract: A method of assembling an endoscope includes inserting a pair of pull wires through an endoscope shaft, coupling distal ends of the pair of pull wires to a distal end of an endoscope shaft, coupling proximal ends of the pair of pull wires to a control wheel assembly, rotationally securing the control wheel assembly into a handle of the endoscope device, and coupling a control level to the control wheel assembly via an opening in the handle. Manipulation of the control lever causes rotation of the control wheel assembly, which then causes deflection of the distal end of the endoscope shaft via the pull wires. The control wheel assembly includes an arcuate member that covers at least a portion of the control wheel assembly to prevent external contaminants from entering the opening in the handle adjacent the control lever.Type: ApplicationFiled: August 2, 2024Publication date: November 28, 2024Inventors: Gary Leong, Reza Yazdi, Matthew Pryl, Bernard Lambrechts, Rohan Sidhu, Yongkook Kim

Publication number: 20240023793Abstract: An endoscope device comprises a handle, a shaft projecting from the handle, wherein the shaft includes a proximal portion and a distal portion relative to the handle, a flexible tip coupled to the distal portion of the shaft, a pair of pull wires extending from the handle portion through the shaft portion and coupled to the flexible tip, a control wheel assembly rotationally secured within the handle and operatively coupled to the pair of pull wires, and a control lever coupled to the control wheel assembly via an opening in the handle. Manipulation of the control lever causes rotation of the control wheel assembly, which then causes deflection of the flexible tip via the pull wires. The control wheel assembly includes an arcuate member that covers at least a portion of the control wheel assembly to prevent external contaminants from entering the opening in the handle adjacent the control lever.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Inventors: Gary Leong, Reza Yazdi, Matthew Pryl, Bernard Lambrechts, Rohan Sidhu, Yongkook Kim

Patent number: 11800971Abstract: An endoscope system, comprises an endoscope device that includes a handle, a shaft projecting from the handle, a flexible tip coupled to a distal portion of the shaft, and a pair of pull wires extending from the handle portion through the shaft portion and coupled to the flexible tip. The handle portion includes a control wheel assembly coupled to the pair of pull wires. The handle includes a control lever coupled to the control wheel assembly. Manipulation of the control lever causes rotation of the control wheel assembly, which then causes deflection of the flexible tip via the pull wires. The control wheel assembly comprises at least two control wheels. Each of the at least two control wheels are capable of independent rotation to provide accurate tensioning of the pair of pull wires during assembly of the endoscope system.Type: GrantFiled: May 17, 2019Date of Patent: October 31, 2023Assignee: Verathon Inc.Inventors: Gary Leong, Reza Yazdi, Matthew Pryl, Bernard Lambrechts, Rohan Sidhu, Yongkook Kim

Patent number: 8549346Abstract: Example systems and methods associated with router synchronization are described. One example method includes reducing a likelihood that a first network device will be favored over a peer device as a router. This likelihood may be increased after the first network device has received a threshold amount of routing information from the peer device. This may allow the first network device to begin performing non-routing related tasks after it starts up without causing interruption of data streams for which the first network device does not have current routing information.Type: GrantFiled: January 17, 2012Date of Patent: October 1, 2013Assignee: Cisco Technology, Inc.Inventors: Sepehr Safari, Ahmad Reza Yazdi, Kaushik Pratap Biswas
