Provided is an endoscope system including an elongated tube with one or more channels extending in a longitudinal direction along the elongated tube. The channels allow inserting of a viewing device for obtaining images from the distal end, inserting of surgical instruments to operate at the distal end, or passing of materials such as air or water. The channel for inserting the viewing device is enclosed or has a cover at the distal end of the elongated tube, such that the viewing device has no direct contact of body tissues, thereby eliminating the need for sterilization. Also provided is a safe and economical method for conducting endoscopy involving one-time use of a tube to keep the viewing device from directly contacting the body tissues.

A multi-directionally guided endoscope includes an endoscope body. The endoscope body is connected to a catheter. At least four pulling wires are evenly distributed in the endoscope body. One ends of the pulling wires are connected to an end of the catheter away from the endoscope body. The pulling wires are respectively fixed to pulling mechanisms. The pulling mechanisms are respectively sleeved on guide rods. The guide rods are fixed in the endoscope body. The endoscope body is provided with a plurality of elongated grooves. One ends of the pulling mechanisms respectively extend from the elongated grooves. The multi-directionally guided endoscope is provided with pulling mechanisms that are simple in structure, convenient to operate, and accurate and stable to pull.

An endoscope system includes an endoscope including an insertion portion including a bending portion, a grasping portion arranged at a proximal end portion of the insertion portion, and an electric actuator configured to bend the bending portion, and an operation unit including an operation member configured to operate the electric actuator and a transmission member configured to wirelessly transmit operation information of the operation member to the electric actuator.

An endoscope includes an insertion portion including a bending portion, an operation portion including an operation lever, a grasping portion including an actuator, and a tube body, in a continuous manner. When the operation lever is tilted, the actuator pulls a wire, whereby the bending portion is bent in a vertical direction and a lateral direction. The actuator is arranged such that a center of gravity of a portion including the insertion portion, the operation portion, the grasping portion, and the tube body is within a range in which at least one of the fourth finger or the fifth finger of the hand grasping the grasping portion is positioned, in a longitudinal direction of the grasping portion.

A medical device control handle or catheter includes deflection assembly and at least one of the following: a disk actuator, a lever actuator and a ring actuator for actuating additional puller wires in manipulation of multiple features of the medical device or catheter independently of each other. The disk actuator has a common rotational axis with but is rotationally independent of the deflection assembly. The lever actuator has a separate rotational axis. The ring is mounted outside of the control handle and rotatable relative to the control handle to actuate another puller wire for manipulating another feature of the catheter. Each of the disk, lever and ring actuators are of a design that allows existing control handles and catheters to be readily modified to include these actuators.

A steerable medical device, such as an endoscope of an endoscopic system, including a handle and an elongate shaft extending distally from the handle to a distal tip, a motor control assembly including a motor control housing configured to detachably interface with the handle, wherein the motor control assembly includes a first motor disposed within the motor control housing and a first gear assembly disposed within the motor control housing, and a first drive axle configured to engage the first gear assembly with a first deflection mechanism disposed within the handle, the first deflection mechanism being configured to deflect the distal tip in a first plane.

The invention relates to a control element for an endoscopic device (A) with a retainer; at least one control wire, which can be moved back and forth in the longitudinal direction of the wire, for control purposes on the endoscopic device (A); a control wire tensioning element guided in the retainer, wherein the control wire is mounted in the control wire tensioning element; and a displacement force application device supported on the retainer, by means of the displacement force application device the control wire tensioning element can be moved relative to the retainer, in order to effect fine adjustment of the control wire. The invention further relates to a control element for an endoscopic device (A), having a housing element with a guide; at least one control wire for control purposes with the endoscopic device (A); a lever element, which can be displaced in the longitudinal direction of the housing element on the guide of the housing element, with the at least one control wire being anchored on the lever element. The anchoring location of the control wire in the lever element is eccentric to the displacement path of the lever element on the guide of the housing element.

The present invention provides a protective sheath, a hysteroscope equipped therewith, and a nephroscope equipped with the same, used to prevent contaminants from contaminating electrical connecting lines connected to the endoscope. The protective sheath includes an inner sheath (1) and an outer sheath (2), which are sleeved together, the outer sheath (2) has a cylindrical structure, the inner sheath (1) includes a straight cylindrical portion and a bell mouth portion, the bell mouth portion is located on an insertion end side of the inner sheath (1), a side wall of the bell mouth portion is provided with a plurality of grooves extending from the bell mouth portion to the straight cylindrical portion, and a plurality of elastic sheets (12) are formed at the insertion end of the inner sheath (1); a connecting portion cooperating with a self-locking quick connector (7) is formed on the inner wall of each elastic sheet (12); and a hollow cavity is disposed between the inner sheath (1) and the outer sheath (2), and a compressed waterproof jacket (3) is disposed in the hollow cavity, one end of the waterproof jacket (3) is fixedly sheathed on the inner sheath (1), and the other end of the waterproof jacket (3) can be pulled through a non-insertion end of the protective sheath.
