Patent number: 8287449Abstract: An endoscope device having a control unit and a bendable probe unit arranged at the distal end of a wire extending from the control unit. The control unit includes a ball shaft and a control lever arranged on the ball shaft. The ball shaft includes a ball member and an outer case that encases the ball member and rotates along the outer peripheral surface of the ball member when the control lever is tilted. The wire is attached to the outer case. The construction facilitates control unit operation, which reduces inspection time and improves inspection accuracy.Type: GrantFiled: May 26, 2005Date of Patent: October 16, 2012Assignee: ARS Co., Ltd.Inventor: Yoshihisa Tanaka
