Abstract: Embodiments of a robotic medical system comprise a steerable instrument that includes a bendable body and a connector assembly configured to detachably connect the bendable body to an actuation unit. A controller is configured to control the actuation unit. The connector assembly comprises a connection receptor coupled to the actuation unit and a connecting shaft coupled to the bendable body. The connecting shaft includes a plurality of driving rods that are attached in a one-to-one correspondence to a plurality of driving wires and that detachably attach to the connection receptor. In a connected state where the bendable body is connected to the actuation unit via the connector assembly, the controller causes the actuation unit to transmit an actuating force from an actuator to a driving rod, and the driving rod actuates or moves a driving wire in a same direction as the actuating force applied by the actuator.

Abstract: A first optical axis of a first optical component is caused to be at a first angle with respect to a first precision surface of the first optical component. A second optical axis of a second optical component is aligned to be at a second angle to a second flat surface of the second optical component. The second angle is equal to or derived from the first angle. The first and second flat surfaces are caused to directly face each other to allow only sliding motion between the first and second flat surfaces. The sliding motion is performed between the first and second flat surfaces until the first and second optical axes are sufficiently collinear.

Abstract: An image processing apparatus and method for detecting a position of a rotating optical fiber is provided. The apparatus includes at least one rotating optical fiber that rotates about an axis of rotation and that emits light towards a surface and at least two stationary fibers for transmitting light reflected from a surface, each of the at least two stationary fibers having a known predetermined position relative to each other and to the axis of rotation of the at least one rotating optical fiber. At least one detector is configured to detect an intensity of light transmitted through each of the at least two stationary fibers within a given time interval and at least one calculator is configured to use the detected intensities and the known predetermined positions of each of the at least two stationary fibers to determine a relative angular position of the rotating optical fiber with respect to the at least two stationary fibers.

Abstract: A fiber optics rotary joint (FORJ) connects a system console to a probe having a rotatable core, and transfers rotational motion to the probe core. The FORJ comprises a stationary optical fiber in optical communication with a rotatable optical fiber, a motor having a hollow shaft, and a fiber connector attached to a distal end of the hollow shaft. The motor is configured to rotate the rotatable optical fiber relative to the stationary optical fiber. The rotatable fiber is attached to the proximal end of the hallow shaft and connected to the fiber connector. The distal end of the stationary optical fiber is directly opposed to and aligned with the proximal end of the rotatable optical fiber such that optical axes of the stationary and rotatable optical fibers are substantially collinear with the rotational axis of the motor. The fiber connector transfers optical power and torque to the probe core.

Abstract: One or more devices, systems, methods and storage mediums for characterizing, examining and/or diagnosing, and/or measuring viscosity of, a sample or object are provided herein. Such information may be obtained in application(s) using a system that includes a rotary junction, an elongated extender or at least one repeater attached to the rotary junction and a rotatable probe attached to the elongated extender and/or the at least one repeater. Examples of such applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments. The extenders and/or repeaters may be used with one or more forms of imaging, such as, but not limited to, Spectrally Encoded Endoscopy (“SEE”) and Optical Coherence Tomography (“OCT”).

Abstract: A connector, a bayonet-style connector, and methods for using the connector or bayonet-style connector are provided. At least one connector includes a receiver having an inner volume to receive a connector, and having a pawl; and a pushbutton or actuator that operates to move or unlock the pawl so that a user can insert and lock and/or unlock and remove the connector using only a single hand of the user. At least one bayonet-style connector includes a connector portion having an opening; a receptacle portion that operates to slidingly accept the connector portion and that has a pawl that operates to engage with the opening to lock the connector portion in place; and an actuator that operates to impart force on the pawl to unlock the connector portion so that a user can remove the connector portion using only one hand of the user.

Abstract: A dual endoscope system, comprising: a main endoscope having a first tubular shaft extending between proximal and distal ends; a secondary endoscope having a second tubular shaft with a distal portion bent with respect to the main endoscope; and a display device to display an image received from the main endoscope and/or the secondary endoscope. The main and secondary endoscopes are joined together along a length of the first and second tubular shafts and are configured to be simultaneously inserted into a lumen. The main endoscope is arranged to acquire a first image of a field of view inside the lumen, and the secondary endoscope is arranged to acquire a second image at an angle to the field of view. The display device displays the first image acquired by main endoscope and a graphic object depicting position and/or orientation of the secondary endoscope with respect to the main endoscope.
