A controller to which an operation for driving an endoscope is input, includes: a controller body formed in a substantially rod shape extending along vertical direction; a main body provided at upper side of the controller body; a grip provided at lower side of the controller body; and an opening provided on a side surface of the controller body and comprising a part into which a treatment tool can be inserted and removed from the upper side, wherein the main body comprises a touch-sensitive interface to which the operation for driving the endoscope is input, and the controller body comprises a pressing surface along an advancing/retreating path of the treatment tool that advances/retreats with respect to the part of the opening.

An endoscope system includes: an endoscope that is capable of bending; an actuator that outputs a driving force for bending the endoscope; and a processor that is capable of communicating with the actuator, wherein the processor controls the actuator by switching at least two modes related to curvature control, generates a first identifier, which is information for identifying a case in which the endoscope is used, generates usage status information, which is information related to a usage status of a mode, and associates and outputs the first identifier and the usage status information.

A medical system includes: an endoscope having an insertion portion; a display; and a processor, wherein the processor generates a three-dimensional model showing a curved shape of the insertion portion, and displays the generated three-dimensional model on the display, acquires first information regarding an insertion direction of the insertion portion, acquires second information regarding a line-of-sight direction of an operator, and determines a line-of-sight direction of the three-dimensional model displayed on the display based on the first information and the second information.

An endoscope system includes: an endoscope comprising a first tube being inserted into a body, a second tube being arranged at a proximal end of the first tube, and a connecting portion connecting the first tube and the second tube so that the first tube can rotate relative to the second tube about a longitudinal axis; and a control device comprising at least one processor. The processor estimates a first guess shape based on information about positions of a plurality of points on the first tube, and estimates a second guess shape based on information about positions of two points on a proximal end side of a region of the first tube inserted into the body.

An endoscope includes: an insertion portion having a joint; a first wire and a second wire fixed on both sides of a central axis in a longitudinal direction of the joint at a distal end of the joint; a first wire sheath which is inserted through an internal path of the insertion portion and through which the first wire is inserted; and a second wire sheath which is inserted through the internal path of the insertion portion and through which the second wire is inserted, wherein the first wire sheath is bundled by a first fastener so as to be close to the second wire sheath, and the first wire sheath and the second wire sheath are bundled so as to be relatively advancing and retreating by the first fastener.

A slider is provided. A slider of the present disclosure includes a slider body disposed to be movable in a linear direction relative to a surgical instrument, and two holders disposed on the slider body for holding ends of a wire between the two holders to retain the wire in an annular shape. At least a first holder of the two holders is provided with an insertion hole for inserting and passing the ends of the wire toward an outside from between the two holders.

A coating film is provided in a cable, a medical hollow tube, a molded article and a hollow tube. The coating film is formed from a rubber composition including a rubber component and fine particles. A static friction coefficient on a surface of the coating film is 0.5 or less. When the coating film is subjected to a testing such that a long fiber non-woven fabric including cotton linters including an alcohol for disinfection with a length of 50 mm along a wiping direction is brought contiguous to the surface of the coating film at a shearing stress of 2×10.sup.−3 MPa to 4×10.sup.−3 MPa, followed by wiping off the surface of the coating film at a speed of 80 times/min to 120 times/min and 20,000 repetitions thereof for a wiping direction length of 150 mm, a difference (an absolute value of a difference) between the static friction coefficients of the coating film before and after the testing is not greater than 0.1.

An endoscope including an elongated shaft. The elongated shaft including: an inner shaft tube in which an optical system is received; an outer shaft assembly including an outer shaft tube and a tubular support body proximally abutting the outer shaft tube; at least one bundle of optical fibers disposed between the inner shaft tube and the outer shaft tube; and an electrical connector arranged between the inner shaft tube and the support body. Where the support body includes at least a first web and a second web each extending radially between an inner surface of the support body and an outer surface of the inner shaft tube, the first web and the second web also extending in a longitudinal direction of the shaft such that an annular space between the inner shaft tube and the support body is divided into at least two segments.

An optical unit includes: a fixing portion including a front frame portion that holds an object-side fixed lens group, a rear frame portion that holds an image-side fixed lens group or an image sensor, and a fixing portion main body formed by using a non-magnetic material; a moving portion that holds a moving lens group and that is arranged on an inner side of the fixing portion main body so as to be slidable with respect to the fixing portion main body; and a voice coil motor configured to move the moving portion along a direction of the optical axis relative to the fixing portion main body, and including a magnetic portion magnetized in a direction intersecting an optical axis of the object-side fixed lens group, and a coil located on an outer side of the fixing portion main body with respect to the magnetic portion.

Disclosed is an intra-oral scanning system including: a scanning device including at least a first magnetic induction coil; a replaceable scanning tip including at least a second magnetic induction coil; the scanning tip being removably connected to the scanning device; wherein the at least first and second magnetic induction coils are configured to provide power transfer and/or a communication signal between the scanning device and the scanning tip during operation of the scanning system.
