Abstract: A laryngoscope is provided and includes a handle, a blade assembly and a plurality of light emitting components. The blade assembly includes a supporting body and a sleeve body. The supporting body is pivotally connected to the handle. The sleeve body is sleeved outside the supporting body. The plurality of light emitting components are disposed on the supporting body and arranged in an arc shape on a first flat plane. Besides, at least one light divergence structure is optionally formed on the sleeve body for diverging light emitted from the plurality of light emitting components, and the supporting body optionally includes a supporting component and a heat dissipating component for conducting heat generated by the plurality of light emitting components to the supporting component. Therefore, the present invention can not only provide bright and wide illumination but also have anti-fogging function.

Abstract: A handheld endoscope has a disposable, single-use portion that includes a fluid hub, cannula, distal tip and is steerable by the operator though actuation of one or two levers. The endoscope also includes multiple-use portion that has a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module that is rotatable to allow viewing by the operator and others. The single-use and multiple-use portions mate and un-mate with each other via physically separated mechanical and electrical connectors. The component of the endoscope can be supplied to users in different combinations of pre-assembled configurations, some in a sterile package. The single use portion can include grasper device that can be actuated by an operator using an actuation tab.

Abstract: Provided is an endoscope system including an elongated tube with one or more channels extending in a longitudinal direction along the elongated tube. The channels allow inserting of a viewing device for obtaining images from the distal end, inserting of surgical instruments to operate at the distal end, or passing of materials such as air or water. The channel for inserting the viewing device is enclosed or has a cover at the distal end of the elongated tube, such that the viewing device has no direct contact of body tissues, thereby eliminating the need for sterilization. Also provided is a safe and economical method for conducting endoscopy involving one-time use of a tube to keep the viewing device from directly contacting the body tissues.

Abstract: An image processing system includes an image sensor receiving light beams to output an output signal corresponding to a horizontal scan period and an image processor electronically connecting to the image sensor and including a signal interceptor and a calculating unit. The image processor transforms the output signal to generate a combining signal. The signal interceptor intercepts a first part of the combining signal corresponding to a first clock period of the horizontal scan period to obtain a first signal and intercepts a second part of the combining signal corresponding to a second clock period of the horizontal scan period to obtain a second signal. The calculating unit calculates the first signal and the second signal to obtain an image pixel data according to a differential calculation. The number of clocks of the first clock period is the same as the number of clocks of the second clock period.
