摘要： A system for modularly assembling a scope device includes an optical module which has an optical housing and a longitudinal member extending distally therefrom. A distal end of the member includes a camera for visualizing a target area, electric wires and a light source extending from the camera to the optical housing. The system also includes a deflector module coupleable with the optical module. The deflector module includes a deflector housing and a deflector shaft extending distally therefrom. The shaft includes a first channel sized, shaped and configured to receive the member therein and a deflectable portion extending along a distal portion of the shaft. The deflector housing includes an actuator for deflecting the deflectable portion, the optical and deflector housings including corresponding connecting elements to engage one another when the member is inserted through the first channel and the deflector and optical housings are coupled.

摘要： An endoscopic device includes a handle body operatively couplable to a shaft housing. The handle body includes an actuator for controlling a distal end of an endoscopic shaft extending from the shaft housing. The device also includes a pull wire attachment configured to operatively couple to a pull wire extending through the shaft housing and the endoscopic shaft to the distal end. Applying tension to the pull wire deflects the distal end of the endoscopic shaft. In addition, the device includes a pulling mechanism coupled to the actuator and having the pull wire attachment extending therefrom. When the pull wire attachment is operatively coupled to the pull wire, actuation of the actuator applies tension to the pull wire and deflects the distal end of the endoscopic shaft.

摘要： A biopsy device adapted for use with an endoscope includes an adaptor that is adapted to be secured relative to an endoscope. The biopsy device includes a pair of jaws that are pivotably disposed relative to the adaptor. An actuator is operably coupled with the first jaw and the second jaw and extends proximally therefrom. The actuator is adapted to move the first jaw and the second jaw relative to the biopsy device housing.

摘要： The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to delivering a variable length stent within a patient. In one example, a stent may include a body comprising coils about a longitudinal axis of the stent and along the length of the stent between a proximal end and a distal end in a substantially helical pattern. The coils may define a lumen along the longitudinal axis through the center of the body. A distal tube may have a wall extending from the distal end of the body. A first aperture may extend through the wall of the distal tube into the lumen. A distal retention member may extend from the distal tube. A distal suture may have a mid-portion. The mid-portion may extend through the first aperture.

The shaft includes a first channel sized, shaped and configured to receive the member therein and a deflectable portion extending along a distal portion of the shaft. The deflector housing includes an actuator for deflecting the deflectable portion, the optical and deflector housings including corresponding connecting elements to engage one another when the member is inserted through the first channel and the deflector and optical housings are coupled.

摘要： A ureteroscope system includes a handle; an elongated shaft extends from the handle to a distal end and includes a working channel which is opened at the distal end; an external member extends from a proximal end to a distal end and is coupled to the shaft, the member includes a hub and a tube defining a first external channel; and a coupling mechanism defines first and second tubes and is coupled the distal end of the member to the distal end of the shaft. The first tube defines a first lumen and the second tube defines a second lumen which is sized and shaped to receive a distal end of the member. A proximal portion of the first tube is sized and shaped to be inserted into a distal portion of the shaft such that the first lumen is opened to the working channel.
