A surgical instrument may comprise an elongated shaft extending between a proximal end and a distal end and defining a longitudinal axis. The surgical instrument may also comprise a plurality of cables extending along the longitudinal axis and a first bending section positioned between the proximal end and the distal end of the elongated shaft. The first bending section may comprise links having pairs of articulation holes extending longitudinally through the links to permit the plurality of pull wires to pass therethrough. Each pair of articulation holes may comprise first and second articulation holes that are spaced apart from the longitudinal axis (i) at different radii and (ii) at a same rotation angle.

An apparatus investigates a technical device using a borescope. The apparatus has: a guide tube which is introducible through a borescope opening on the technical device to be inspected using the borescope; and a repeatedly plastically deformable carrier configured to guide a borescope head arranged at one end of the carrier. The guide tube is designed to deform the carrier during the passage of the carrier through the guide tube.

The present invention relates to a chest tube insertion device using an endoscopic guide, the device having a structure comprising: a tube insertion guide body which is made from a transparent or semitransparent synthetic resin material and which is introduced into the thoracic cavity of the human body while being flexibly bendable, an endoscopic tube disposed inside the tube insertion guide body; a chest tube formed as a structure for encompassing the outer side of the tube insertion guide body, so as to be spaced from the endoscopic tube; a guide holder for performing an endoscopic guide function and a tube insertion guide body fixing function when the tube insertion guide body is inserted into the thoracic cavity; and a handle part to which the guide holder is separably coupled.

Systems and methods for supporting image-guided procedures include an elongate device including a steerable distal end and a shape sensor located along a length of the elongate device and one or more processors coupled to the elongate device. While the elongate device is being traversed through one or more passageways of a patient, the one or more processors are configured to detect a data collection event, and capture, in response to detecting the data collection event, a plurality of points along the length of the elongate device using the shape sensor. In some embodiments, an insertion depth of the elongate device is monitored. In some embodiments, the data collection event is detected when the insertion depth is beyond a threshold insertion depth, no change of the insertion depth is detected for longer than a threshold period of time, or the insertion depth is beyond a threshold retraction distance.

A gastronomy tube includes an elongate tubular portion, a stop, and at least one wire loop. The elongate tubular portion is configured to extend along a length of an endoscope and to reversibly attach to the endoscope. The stop is at a proximal end of the elongate tubular portion. The at least one wire loop is at a distal end of the elongate tubular portion and is configured to extend distally from a distal end of the endoscope when the elongate tubular portion is attached to the endoscope.

A face mask (90) comprises an instrument shielding apparatus (91) which comprises an instrument shielding device (92) which is connected to the face mask (90) by an adapter (89). The adapter (89) comprises an instrument accommodating housing (15) through which an instrument bore (25) extends therethrough. The instrument accommodating housing (15) terminates at one end in a first main port (20) engageable with an instrument port (7) of the face mask (90), and in the other end in a second main port (23). The instrument shielding device (92) comprises a shielding sleeve (95) a first end (96) of which is secured by a coupling ring (98) to the second main port (23) of the adapter (89), and a second end (97) of which is secured in a storage chamber (94) of a sleeve storing housing (93) of the instrument shielding device (92). The sleeve storing housing (93) is sealably engageable with a proximal end (58) of an endoscope (10), and the shielding sleeve extends from a collapsed stored state in the storage chamber (94) to the adapter (89) for shielding the endoscope (10).

The present invention relates to a hysteresis compensation control apparatus of a flexible tube and a method thereof for compensation control of hysteresis of a surgical instrument disposed in a channel of an overtube. The hysteresis compensation control apparatus includes: an input unit receiving image information and tension information of a flexible surgical instrument required for mode switching; a mode switching determining unit for determining a current state of the surgical instrument on the basis of the image information of the surgical instrument, and generating a control mode switching signal according to the current state of the surgical instrument; a mode switching unit for switching a control mode from a flexible tube control based on the image information to a flexible tube control based on the tension information according to the control mode switching signal; and a compensation control unit for compensatingly controlling a flexible surgical instrument having hysteresis characteristics on the basis of a tension error value calculated by a learning model.

System and method for advancing and retracting a tubular medical instrument within a body lumen and evacuating lumen material therefrom. A shaft of the medical instrument is inserted through a central bore of a probe, an evacuation adaptor, and a swivel fastener unit, respectively mounted onto a distal carriage, a central carriage, and a proximal carriage of a translation mechanism. The probe is directed toward cavity entrance of body lumen using an adjustment mechanism coupled to a translation mechanism beam. A central probe unit of probe is maintained sealingly coupled to cavity entrance by propelling distal carriage along beam. The evacuation adapter is maintained sealingly coupled to the probe by propelling central carriage along beam, concurrent with displacement of a hollow tube of probe relative to central probe unit. Lumen material is evacuated using evacuation adaptor. The medical instrument is advanced and retracted by propelling proximal carriage along beam.
