The rotatable spool is configured to direct the pull wire to the elongate shaft at an angle. The rotatable spool is configured to translate in coordination with actuation of the elongate shaft to control the angle of the pull wire relative to the elongate shaft.

Disclosed embodiments provide an apparatus and method of removing tissue from a body of a human or non-human animal. The disclosed embodiments includes a tool that may have a cutting edge to drill into tissue. The tool has magnetizable segments, which may be translated or rotated by an applied magnetic field

Computer-implemented methods for modeling a surgical correction for a patient, and associated systems are disclosed herein. In some embodiments, the method includes obtaining patient data. The image data can depict a native anatomical configuration of a region of a patient's spine. The method also includes generating a virtual model of the patient's spine in the native anatomical configuration and/or a corrected anatomical configuration. The method can also include identifying one or more soft tissue surgical steps, predicting an effect of the soft tissue surgical steps, and generating a surgical plan for achieving the corrected anatomical configuration. The soft tissue surgical step can adjust an intraoperative mobility of vertebrae of the spine to achieve the corrected anatomical configuration. The surgical plan includes at least one of the soft tissue surgical steps to help facilitate movement of the vertebrae to the corrected anatomical configuration.

A medical device includes a shaft comprising a proximal end portion and a distal end portion. A beam has a proximal end portion, a distal end portion, and a middle portion, and one or more strain sensors are on the middle portion. The proximal end portion of the beam is matingly coupled to the distal end portion of the shaft to form an interface. The beam comprises a discontinuity between the interface and the middle portion of the beam. In some embodiments, the medical device includes a link and the distal end portion of the beam is matingly coupled to the link to form a second interface. A second discontinuity is between the second interface and the middle portion of the beam. In some embodiments, an anchor is coupled to the shaft and the proximal end portion of the beam is matingly coupled to the anchor.

A system may render, within a graphical user interface associated with a computer-assisted medical system, a graphical tag element associated with a physical location within a region of interest. The system may detect a user interaction with the graphical tag element. The system may further direct, in response to the detecting of the user interaction with the graphical tag element, the computer-assisted medical system to adjust a pose of an instrument based on the physical location within the region of interest.

A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.

The present invention relates to an endoscope suturing device and, more specifically, to an endoscopic suturing device capable of suturing a range of incisions by using an endoscope. According to the present invention, a wide range of incisions can be continuously sutured with high suturing power by using an endoscope, the suturing procedure time can be shortened, and a suturing method using a suture can minimize leftover foreign substances in the body, and thus can prevent side effects caused by the foreign substances. In addition, by using an endoscope, suturing with high-reliability is possible regardless of the range of suture areas, and thus the present invention can be used for simple suturing procedures and various internal surgeries such as gastrointestinal reduction surgery and NOTES, which uses a natural orifice.
