The present subject matter provides a system for allowing controlled access of a tool to all sides of an elevated tissue in body of a patient, the system including: a rail configured to surround the elevated tissue; and at least one vehicle configured to move along the rail and carry at least one tool configured to manipulate the elevated tissue. Also provided is a method for cutting an elevated tissue in a body of a patient, the method including: inserting a rail to a vicinity of the elevated tissue; surrounding the elevated tissue with the rail; placing a vehicle on the rail; connecting a cutting device to the vehicle; and moving the vehicle along the rail while cutting the elevated tissue with the cutting device. Additional embodiments of the system and method are disclosed herein.

A sheath, including a sheath body, a handle, and a traction wire. The traction wire includes a first traction wire. The handle includes a first guide rail member and a first slider. The first slider is connected to the first traction wire. A first groove is provided on an outer wall of the first guide rail member along an axial direction. The first groove includes a first bottom and a first side wall. The first slider slides in the first groove along the first side wall so as to drive the first traction wire to move. At least part of the outer wall of the first guide rail member is radially recessed to a central shaft of the first guide rail member to form the first groove.

Disclosed is a surgical member driving apparatus. According to an embodiment of the disclosure, a surgical member driving apparatus for operating a surgical member detachably mounted to an endoscope includes a cartridge module including a base unit fastened to one end portion of the endoscope and coupling with the surgical member at one side, a wire including a first end portion coupled to the base unit and transmitting driving force to the base unit, and a cartridge provided with a power transmitter coupled to a second end portion of the wire; and a driving module including an accommodating portion to which the cartridge is detachably coupled, and providing the driving force to the wire of the cartridge module coupled to the accommodating portion.

A drive system for a handheld rotary medical device including a force absorption system incorporated in a drive coupling of the drive system is disclosed. The force absorption system may be included in the drive coupling whereby force absorption system absorbs linear forces aligned with a longitudinal axis of the drive coupling. As such, the force absorption system permits limited linear movement of a rotary surgical implement, which may be a shaver, burr or the like, relative to a drive shaft and handheld housing.

A tissue specimen retrieval bag assembly includes a tissue specimen bag having an open proximal end and a closed distal end, the proximal end including a cuff defined therein and extending therearound. A flexible bag brim is disposed within the cuff, the flexible bag brim transitionable between a first, collapsed configuration and a second, expanded configuration. The flexible bag brim includes a D-Shaped cross section configured to facilitate both furling the tissue specimen bag onto itself around the bag brim when the bag brim is disposed in the second, expanded configuration and securing the tissue specimen bag in a desired furled configuration. The flexible bag brim defines a cavity therein configured to facilitate compression thereof and to facilitate handling of the bag brim by a surgical instrument.

Surgical stapling instruments are disclosed comprising a staple cartridge, a firing member, and a cartridge lockout configured to prevent the firing member from being advanced through the staple cartridge if the staple cartridge has been already spent. The stapling instruments further comprise a lockout in the shaft that responds to the cartridge lockout blocking the firing member.

A powered handle assembly includes a motor assembly, a rack, a spur gear, and a manual retract mechanism. The spur gear is movable from a position engaged with the motor assembly and the rack to a positioned disengaged from the motor assembly and engaged with the rack to facilitate manual retraction of the rack.

A seeker device for facilitating access to a desired location within an ear, nose, throat or other location in a body may include a proximal shaft, an elastic distal portion, and an atraumatic distal tip. The elastic distal portion has a default shape with at least one curve to facilitate advancement of a distal end of the elastic distal portion through various anatomical passageways, toward the desired location. In some embodiments, the seeker device may be paired with a dilator device, to perform a dilation procedure on an anatomical structure in the ear, nose, throat or other part of the body. In other embodiments, the seeker device may be paired with a flexible endoscope, to facilitate visualization of an anatomical structure or area.

A kit for extracting a tissue specimen includes a specimen container having a proximal rim and a specimen bag operably supported about the proximal rim and depending therefrom. The specimen bag includes a plurality of ribs depending from the proximal rim having a series of mechanical interfaces associated therewith and extending therealong. The kit also includes a cutting guard having a body with proximal and distal ends. The distal end is configured for insertion within the specimen bag when disposed within an incision and the proximal end defines an opening therein configured to facilitate introduction of one or more surgical instruments therethrough. The cutting guard includes one or mechanical interfaces operably associated with the body of the cutting guard configured to selectively engage one of the series of mechanical interfaces of one of the plurality of ribs of the specimen container upon insertion of the cutting guard within the incision.

A surgical apparatus system for minimally invasive surgery (MIS) which includes a wrist assembly. The wrist assembly includes a first jaw, a first actuation hub, and a cable redirecting hub operably coupled to the first actuation hub, a second jaw, a second actuation hub, a housing for the first and second jaws, a first cable, a second cable, a third cable, rotational position sensors, and a control system. The first and second jaws of the wrist assembly are movably opposed, and the cables are configured such that applying tensions upon them cables produces rotation about a jaw axis. The wrist assembly may further include a hinge-rotary assembly to configured to provide rotation about a pitch axis and/or a roll axis. The wrist assembly may further include a fourth cable configured such that applying tensions upon the fourth cable and the opposing cable produces rotation about a pitch axis.
