A medical device includes a handle including an axle, a device shaft extending from the handle to a distal end, and a control device. The control device is coupled to the handle, and the control device includes a knob. The knob is rotatable relative to the handle. The control device also includes a control shaft extending from the knob, at least one spring clutch including two legs, and a spool. The spool is rotatable relative to the axle. The control device also includes one or more wires coupled to the spool. Rotation of the knob is configured to rotate the control shaft, causing the at least one spring clutch to loosen, the spool to rotate, and the one or more wires to move.

A medical manipulator including an insertion portion, where the insertion section including a bending portion and an end effector disposed on a distal end side of the insertion portion. The medical manipulator further including an actuator configured to generate a first drive force for moving the bending portion; a lever configured to generate a second drive force for moving the bending portion, the lever being used to move the bending portion instead of the actuator; a wire configured to transmit the first drive force or the second drive force to the bending portion; and a transmission blocking device configured to switch from the first drive force to the second drive force.

This invention relates to an endoscopic device, and more particularly but not exclusively to an endoscopic device suitable for use in diagnostic and/or surgical procedures. The endoscopic device includes a base and a shaft extending from the base. The shaft is at least partially flexible and includes a bending section that is selectively displaceable between a straight configuration and a bent configuration. The endoscopic device also includes an actuation arrangement for selectively displacing the bending section between the straight and bent positions. The actuation arrangement includes at least one actuator which is at least partially made from a shape memory alloy, and which is configured to displace the bending section of the shaft when electric current is passed therethrough. The actuator is located inside the base of the device.

A flexible tube insertion apparatus includes a flexible tube having flexibility and configured to be inserted into an object to be inserted, one or more external force detectors disposed on the flexible tube and configured to detect a force of an external force applied to the flexible tube when the flexible tube is twisted in at least one direction, and a providing device configured to provide twisting information regarding a twisting direction of the flexible tube for releasing a loop section formed in the flexible tube, according to a direction in which the flexible tube is twisted and the detected force of the external force.

Integrated hysteroscopic treatment systems which includes an endoscopic viewing system, a fluid management system, a resecting device and a controller for operating all the systems.

The present invention relates to an intubation system comprising insertion unit to be connected to a bending section of a medical instrument comprising an inner elongated shaft structure being capable of torque transmission around its length axis and an outer elongated shaft structure surrounding the inner elongated shaft structure and having a continuous outer surface, and an orientation controller being attached to the inner elongated shaft, such that when the orientation controller rotates, the bending section turns around itself.

Provided are robotic systems and methods for navigation of luminal network that detect physiological noise. In one aspect, the system includes a set of one or more processors configured to receive first and second image data from an image sensor located on an instrument, detect a set of one or more points of interest the first image data, and identify a set of first locations and a set of second location respectively corresponding to the set of points in the first and second image data. The set of processors are further configured to, based on the set of first locations and the set of second locations, detect a change of location of the instrument within a luminal network caused by movement of the luminal network relative to the instrument based on the set of first locations and the set of second locations.

Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a shaft having a distal end and a proximal end; a handle attached to the proximal end of the shaft; and an end effector attached to the distal end of the shaft; wherein the shaft comprises a flexible portion, a first articulating portion and a second articulating portion, wherein the flexible portion extends distally from the handle, the first articulating portion extends distally from the flexible portion, and the second articulating portion extends distally from the first articulating portion; wherein at least one articulation cable extends from the handle to the first articulating portion, such that when tension is applied to the at least one articulation cable, the first articulating portion deflects; wherein a plurality of articulation cables extend from the handle to the second articulating portion, such that when tension is applied to at least one of the plurality of articulation cables, the second articulating portion deflects.

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 laryngoscope for orotracheal intubation, includes a tubular body that serves as a guide for an endotracheal tube. The tubular body has an adjustable head which is inserted into the pharynx through the mouth following the anatomical curvature until it reaches the larynx and vocal cords. The head may be equipped with a lighting and display system that can be connected to an external screen. The head can be oriented by means of actuators so that it can be directed towards the entrance to the airways,
