This invention is directed to a medical device having a longitudinal axis, and including a handle and a catheter. The handle can include a body having a proximal end and a distal end, an actuator moveably coupled to the body, and a handle control member coupled to the actuator, wherein the actuator can be configured to move relative to the body to move the handle control member. The catheter can include a shaft having a proximal end and a distal end, wherein the proximal end of the shaft and the distal end of the body can be configured for releasable coupling. The catheter can also include a steering section located along the shaft and a catheter control member coupled to the steering section, wherein the catheter control member can be configured to move relative to the shaft to move the steering section relative to the longitudinal axis. The medical device can also include a securing member configured to move relative to at least one of the handle and the catheter to releasably couple the handle control member to the catheter control member.

The present invention relates to an endoscopic treatment instrument, and more particularly, to an endoscopic treatment instrument including a detachable end-effector and a contamination prevention cover. The endoscopic treatment instrument includes an end-effector for performing treatment in the endoscopic surgery or an endoscope treatment, a connection section being detachably coupled to an end of the end-effector, and a contamination prevention cover being coupled to the connection section or the end-effector and surrounding a portion of an outer peripheral surface of the connection section so as to prevent contamination of the connection section. According to an embodiment of the present invention, since only the end-effector is separable for replacement and the cover is formed to protect a control unit, it is possible to prevent cross infection between patients caused by the contamination of the end-effector and the control unit.

A surgical stapling apparatus. Various embodiments include a rotatable elongated body that extends from a rotatable shroud on handle assembly and has a distal end configured for attachment to a disposable loading unit. The apparatus further includes a lockable rotation system for selectively locking the rotatable shroud to prevent rotation thereof about a longitudinal axis.

A marker delivery device includes a housing, a flexible push rod, and a wheel. The push rod includes a first transverse dive surface and a deployer tip. The deployer tip is configured to receive a biopsy site marker. The wheel includes a second transverse drive surface. The first transverse drive surface is configured to be driven by the second transverse drive surface to translate the push rod distally.

A tissue displacing and fastening device is provided for manipulating and fastening tissue together. The device includes a tissue displacing elements, which displaces tissue. A fold is formed from the displaced tissue and the tissue is fastened together to secure the fold.

A laparoscopic surgical apparatus for performing a surgical procedure through a single incision in a patient's body includes a gross positioning arm supported on a moveable platform, the gross positioner including a head; at least one articulated tool positioning apparatus coupled via a tool controller to an underside of the head, the articulated tool positioning apparatus being configured to receive a tool for performing surgical operations, the tool controller being actuated by the head to cause movements of the articulated tool positioning apparatus for performing surgical operations; and wherein the gross positioner is configured to permit the head to be positioned to facilitate insertion of the articulated tool positioning apparatus through the incision into the patient's body.

An end effector for a robotic surgical tool includes a lower jaw, and an upper jaw opposite the lower jaw and including a first component part matable with a second component part at a mated interface that extends longitudinally and vertically.

A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

A surgical instrument is provided having an actuator mechanism with an integrated extension element. The surgical instrument comprises a handle assembly, an elongate shaft, and an end effector. The end effector comprises a jaw assembly having atraumatic pads to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to a movable handle of the handle assembly. The actuator can have an integrated extension element that allows the actuator to translate within the elongate shaft upon application of a relatively low force and translate and extend upon application of a relatively higher force to the actuator to limit the force applied by the jaw assembly. The actuator also utilizes forces stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue when the tissue volume decreases while in the jaws.

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.
