URETEROSCOPE DEVICE AND METHOD FOR USING OF SUCH A DEVICE

A medical device includes a sheath extending longitudinally from a proximal end to a distal end and a handle coupled to the proximal end of the sheath. The handle includes a deflection lever coupled thereto. The deflection lever is rotatable proximally and distally along the handle to deflect a distal end of the shaft to which it is operably coupled and a locking mechanism movable between an locked configuration in which the locking mechanism engages an engagement feature on the outer surface of the handle, preventing the deflection lever from rotating and locking the distal end of the shaft in a desired position, and an unlocked configuration in which the locking mechanism releases the engagement feature to allow rotation of the deflection lever and deflection of the distal end of the shaft. 一种医疗装置，其包括从近侧端部纵向延伸到远侧端部的护套和联接到护套的近侧端部的手柄。手柄包括与其联接的偏转杆。偏转杆可沿手柄向近侧和远侧旋转，以偏转与该偏转杆可操作地联接的轴的远侧端部，锁定机构可在锁定构造和解锁构造之间移动，在锁定构造中，锁定机构接合手柄的外表面上的接合特征，以防止偏转杆旋转并将轴的远侧端部锁定在期望的位置，在解锁构造中，锁定机构释放接合特征，以允许偏转杆旋转和轴的远侧端部偏转。
