Embodiments of the disclosure include an endoscope accessory assembly for use on an endoscope, during procedures. The endoscope accessory assembly may comprise an accessory device comprising a first base, a plurality of flexible struts, and webbing connecting each of the flexible struts. The accessory device is configured to receive a distal end of an endoscope. The endoscope accessory assembly may further comprise a dimension-compensating component comprising a second base, a plurality of flexible arms extending radially out from the second base, and at least one chamber at a distal end of the flexible arms. The accessory device is configured to be over-molded onto the dimension-compensating component in order to form the endoscope accessory assembly.

A filter assembly is configured to optically couple a camera head to an endoscope. The filter assembly includes a first end adapted to be removably coupled to the camera head and a second end opposite and spaced apart from the first end, the second end adapted to be removably coupled to the endoscope. The filter assembly includes an optic housing disposed between the first end and the second end, the optic housing includes an optical path length maximizer and a first window. The first window has a first surface that is angled with respect to a plane that is perpendicular to a longitudinal axis of the optic housing so as to minimize a narcissus reflection within the optic housing and an optical filter to reject laser irradiation.

A method for producing an endoscope that includes an endoscope head and an optic tube, including the steps of providing the endoscope head, providing the optic tube, and pushing a proximal end area of the optic tube into a distal end area of the endoscope head. The distal end area of the endoscope head is press-fitted with the proximal end area of the optic tube.

A joint driving actuator that includes an ultrasonic motor that generates driving force for driving a joint, the ultrasonic motor including a stator fixed to a side of one arm that relatively rotates in the joint and a rotor fixed to a side of another arm that relatively rotates in the joint, the stator including a piezoelectric element that generates ultrasonic vibration, a torque sensor that detects external force applied to the joint, and an encoder that detects a rotational angle of the ultrasonic motor, the encoder being mounted on the one arm, the stator being fixed on the side thereof, and the torque sensor being mounted on the another arm, the rotor being fixed on the side thereof.

A sheath assembly is adapted for an ultrasonic probe and includes a plug portion and a sheath portion connected to each other. One end of the plug portion of the sheath assembly is used for detachably and fixedly connecting with a connecting butt joint portion of the ultrasonic probe, so that the plug portion and the connecting butt joint portion are detachable after the ultrasonic probe is used. An inside of the plug portion communicates with an inside of the sheath portion to receive a torque transmitting portion of the ultrasonic probe.

Provided is an arthroscopic system including an disposable arthroscope having a distal end and a proximal end, and including a light source, a lens set, an image sensor, a transmitter, and a control interface. The arthroscopic system eliminates the possibility of infecting the patient with contaminated devices by its cost-effectively disposable arthroscope. Also provided is a method for image rotating in an arthroscopic system.

A magnetic coupling is provided having two rings that are arranged concentrically in relation to one another, which are each mounted to be rotatable in relation to one another. An arrangement of at least three magnetic dipoles is respectively arranged on both rings, the magnetic dipoles facilitating magnetic coupling of the rings and a transmission of torque from a driving ring to a driven ring of the two rings. The magnetic dipoles of the arrangements at the driven ring and/or at the driving ring is/are aligned such that two like magnetic poles, which adjoin one another on the respective other ring, are always followed by an unlike magnetic pole, and the magnetic poles adjoining one another at the respective other ring are arranged in a manner corresponding to one another such that the two rings are magnetically coupled in an equilibrium position.

There are disclosed embodiments of devices and methods for imaging the inside of a body part, particularly a blood vessel. In particular embodiments, a catheter has a tip chamber, within which is an ultrasound transducer mounted on a pivot mechanism, a motor for turning the transducer, and an implement for pivoting the transducer. Examples of such an implement are a linear motor, a shaft or filament, and the pivot mechanism may be biased to return to a base position when the implement is not pivoting the transducer. In other embodiments, a mirror reflecting ultrasound signals from the transducer may be rotated and/or pivoted, using similar mechanisms.

An endoscope includes a handle connected to a flexible, steerable, kink-resistant insertion tube. An endoscope insertion tube may include a shaft, a lower durometer section proximate to a distal end of the shaft, and a higher durometer section positioned between the lower durometer section and a medium durometer section. The endoscope insertion tube may further include a fourth thermoplastic laminate section proximate to a proximal end of the shaft and having a higher durometer. A method of making an endoscope insertion tube may include inserting a mandrel with one, two, or more lateral slots and a liner into a shaft, wherein the liner is positioned between the mandrel and the shaft, bonding a bonded portion of the liner to an inner surface of the shaft, separating other portion(s) of the liner from the shaft, and inserting a first deflection wire in a gap between the shaft and the unbonded portion(s) of the liner.

The present disclosure, in its various aspects, is directed to instrument accessory devices, implementation methods, and related delivery systems. Embodiments according to the present disclosure, including as described herein, may increase the effectiveness and efficiency of endoscopic procedures, such as Endoscopic Retrograde Cholangiopancreatography (ERCP). In one example, an embodiment includes an instrument accessory device with an expandable member, the device configured to receive an instrument through an instrument lumen, wherein the outer surface may comprise an expandable material. The device may comprise a constrainment element disposed about the outer surface of the expandable member, the constrainment element comprising a proximal end, a distal end, an inner surface, and an outer surface.
