Devices used to provide transseptal access are disclosed. The devices may comprise at least one cannula, a needle, and a handle. The cannula and the needle may be configured to be inserted through a dilator while not damaging a lumen wall of the dilator. The handle may be configured to lock the needle in a retracted position. The devices may be configured to telescopically advance the needle through an atrial septum.

A surgical system includes a surgical arm including at least a distal segment. The surgical system further includes a drape disposed over the surgical arm such that the surgical arm is at least partially covered by the drape. An instrument connector is coupled to the distal segment of the surgical arm through the drape and includes a stem and a shaft. The shaft is configured to receive a surgical instrument. When the instrument connector is coupled to the surgical arm, the instrument connector secures a portion of the drape against the distal segment of the surgical arm. Other example surgical systems and surgical arms are also disclosed.

The present disclosure describes a spinal fixation system comprising a telescoping spinal rod, as well as methods of its use and a guide tower for use therewith. The telescoping rod can be extended after it has been inserted into the patient below the fascia, which permits it to be extended in the sub-fascial space.

A surgical instrument comprises a hand-held portion configured to be manipulated by a user and a pivoting portion operatively coupled to the hand-held portion. The pivoting portion is configured to pivot with respect to the hand-held portion according to first and second degrees of freedom. The pivoting portion includes an accessory drive motor, an accessory drive member configured to be driven by the accessory drive motor, a plurality of lead screws, a carriage including a central aperture axially extending through the carriage and configured to interface with and linearly translate along the plurality of lead screws, and a linear drive motor configured to rotate the plurality of lead screws to linearly translate the carriage relative to the hand-held portion with respect to a third degree of freedom. The accessory drive member extends through and is configured to move within the central aperture of the carriage.

A surgical instrument including an end effector, a shaft assembly defining a longitudinal axis extending proximally from the end effector, a first drive operatively connected to a first portion of at least one of the end effector or the shaft assembly, and an activating mechanism operatively connected to the first drive. The first drive longitudinally translates relative to the longitudinal axis from a first drive position toward a second drive position to respectively actuate the first portion from a first portion position toward a second portion. The activating mechanism selectively direct translation of the first drive from the first drive position toward the second drive position by rotating from a first rotational body position toward a second rotational body position or translating from a first translational body position toward a second translational body position.

A surgical robotic arm (100) includes a presurgical positioning assembly (10), a telecentric manipulating assembly (20) and an executing assembly (30); the telecentric manipulating assembly (20) includes a static platform (21), a first movable platform (22) and a plurality of first telescopic elements (23) disposed between the static platform (21) and the first movable platform (22); the executing assembly (30) has a preset telecentric fixed point; coordinated extension and retraction among the plurality of first telescopic elements (23) is capable of controlling the first movable platform (22) to move relative to the static platform (21) and drive the executing assembly (30) to extend and retract and swing; a swing center of the executing assembly (30) is the telecentric fixed point; and a telescopic path of the executing assembly (30) passes through the telecentric fixed point.

A surgical instrument comprises a hand-held portion configured to be manipulated by a user and a pivoting portion operatively coupled to the hand-held portion. The pivoting portion is configured to pivot with respect to the hand-held portion according to first and second degrees of freedom. The pivoting portion includes an accessory drive motor, an accessory drive member configured to be driven by the accessory drive motor, a plurality of lead screws, a carriage including a central aperture axially extending through the carriage and configured to interface with and linearly translate along the plurality of lead screws, and a linear drive motor configured to rotate the plurality of lead screws to linearly translate the carriage relative to the hand-held portion with respect to a third degree of freedom. The accessory drive member extends through and is configured to move within the central aperture of the carriage.

A stool management system having a tubular body including a first end section disposable in a rectum of a patient and a second end section including a first connector which detachably mates with a second connector coupled to a collection container which receives waste matter passed through the tubular body from the bowel of the patient.

A telescoping access cannula comprising: an outer tube; an inner tube carried by the outer tube, the inner tube being coaxial with the outer tube and longitudinally movable relative to the outer tube; and a rotatable member carried by the outer tube and connected to the inner tube, wherein rotation of the rotatable member causes longitudinal movement of the inner tube relative to the outer tube.

A clot retrieval device featuring a capturing basket coupled to a delivery shaft. The capturing basket is deployable to the side of a clot in a blood vessel. The capturing basket is configured to allow for the clot to ingress into the capturing basket and surround at least a portion of the clot. The capturing basket can be torqued by torquing at the proximal end of the catheter resulting in the rotation of the capturing basket about its longitudinal axis.
