Embodiments of a robotic medical system comprise a steerable instrument that includes a bendable body and a connector assembly configured to detachably connect the bendable body to an actuation unit. A controller is configured to control the actuation unit. The connector assembly comprises a connection receptor coupled to the actuation unit and a connecting shaft coupled to the bendable body. The connecting shaft includes a plurality of driving rods that are attached in a one-to-one correspondence to a plurality of driving wires and that detachably attach to the connection receptor. In a connected state where the bendable body is connected to the actuation unit via the connector assembly, the controller causes the actuation unit to transmit an actuating force from an actuator to a driving rod, and the driving rod actuates or moves a driving wire in a same direction as the actuating force applied by the actuator.

The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

A visual system for laparoscopy comprising a visual device having a visual head member and an elongated connector; a manipulation device having a handheld operation portion, an insertion portion and a first contact element; and an external device comprising means to communicate with the vision head member, via the first contact element, when the elongated connector is mounted in an lumen of the insertion portion. The insertion portion of the manipulation device is configured to be extendable out from a body cavity through an airtight passage whereby the elongated connector is configured to be slidably mounted into the lumen of the insertion portion outside of the body cavity upon the insertion portion is withdrawn into the body cavity.

A method of making an introducer includes providing a translucent material that is formed into an elongate introducer, wherein the introducer has a lumen on an end thereof, and sealing the lumen with a sealing mechanism, wherein the seal is one of a duckbill seal or a one-way valve.

An enhanced flexible robotic endoscopy apparatus includes a main body and flexible elongate shaft. The main body comprises a proximal end, a distal end and a housing that extends to the proximal end and the housing comprises a plurality of surfaces and a plurality of insertion inlets which reside on at least one of the surface of the housing at the proximal end of the main body, through which a plurality of channels for endoscopy are accessible. Each of the insertion inlets has insertion axis corresponding thereto, along which flexible elongate assemblies are insertable, with the insertion axes of the insertion inlets being parallel to the central axis of the flexible elongate shaft at the proximal end of the flexible elongate shaft.

A sleeve assembly is described for coupling a colonoscope insertion tube to an add-on tube. In some embodiments, the sleeve assembly defines an elongated lumen and comprises an inner sleeve sized to receive an insertion tube of a colonoscope, an outer sleeve encircling the inner sleeve, and one or more add-on tubes positioned between the inner sleeve and the outer sleeve. In some embodiments, at least the inner sleeve is collapsible to fit tightly over a colonoscope insertion tube received within the inner sleeve. In some embodiments, the inner sleeve is coupled to the outer sleeve at one or more locations along the length of the inner sleeve so that collapsing of the inner sleeve brings the outer sleeve radially closer to the inner sleeve, approximating the one or more add-on tubes to a colonoscope insertion tube received within the inner sleeve.

The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

Some implementations of the disclosure are directed to a portable endoscope system. The portable endoscope system may comprise: an endoscope, comprising: a distal end; a proximal end; an endoscope housing integrated into a proximal part of the proximal end; an illumination device housed by the housing; and an endoscope connector to removably couple the endoscope to a first end of a cable connector; and a portable control box separate from the endoscope and to removably couple to the endoscope via the cable connector, the portable control box comprising: a portable control box connector to removably couple the portable control box to a second end of the cable connector; a power source to power the endoscope; a control board to control the endoscope; and a control box housing to house the power source and the control board.

A detachable endoscope includes an insertion unit including an illuminating and image pickup unit, an operation unit configured to bendingly operate a front end of the insertion unit, and a detachable unit configured to detachably couple the insertion unit and the operation unit to each other, wherein the detachable unit comprises: a first detachable module disposed at the insertion unit in such a manner as to be connected to respective one ends of first and second operating wire and third and fourth operating wires juxtaposedly arranged in the insertion unit; and a second detachable module disposed at the operation unit in such a manner as to be connected to respective both ends of upper and lower chains wound around upper and lower sprockets of the operation unit.

A laryngoscope assembly having a handle for connection with a laryngoscope blade and wherein the handle includes an additional mechanism for securing the blade to the handle. A locking mechanism is a spring provided for holding the blade in position on the handle and preventing side to side movement of the blade with respect to the handle.
