Provided herein as systems, apparatus, and methods for the effective and minimally invasive deployment of medical devices or therapeutic agents using a steerable guidewire/catheter assembly. The steerable guidewire and/or catheter has a bendable distal portion comprising an ionic electroactive polymer actuator, which is allowed to deform, bend or expand from its original shape in at least one dimension.

A surgical device controllable by a surgical robotic system is provided. The surgical device includes a housing capable of being coupled to the surgical robotic system, a drive system at least partially mounted in the housing; and a shaft rotatably coupled to the drive system at a first end of the shaft. The surgical device further includes a tissue-removal assembly coupled to the second end of the shaft. The tissue-removal assembly includes a first cutting member having a plurality of rotatable blades. The first cutting member is coupled to a second end of the shaft. The tissue-removal assembly further includes a second cutting member, one or more support elements slidably or fixedly coupled to the second cutting member, and one or more extendable elements slidably or fixedly coupled to the second cutting member.

Systems, devices and methods are provided in which an instrument can translate along an insertion axis. Rather than relying primarily on a robotic arm for instrument insertion, the instruments described herein have novel instrument based insertion architectures that allow portions of the instruments themselves to translate along an insertion axis. For example, an instrument can comprise a shaft, an end effector on a distal end of the shaft, and a handle coupled to the shaft. The architecture of the instrument allows the shaft to translate relative to the handle along an axis of insertion. The translation of the shaft does not interfere with other functions of the instrument, such as end effector actuation.

A surgical end effector may comprise first and second jaw members. The second jaw member may comprise an offset proximal supply electrode that is positioned to contact an opposing member of the first jaw member when the first and second jaw members are in the closed position. The second jaw member may also comprise a distal supply electrode that is positioned distal of the offset proximal electrode and is aligned with a conductive surface of the first jaw member when the first and second jaw members are in the closed position. When the first and second jaw members are in the closed position, the proximal supply electrode may be in contact with the opposing member and the distal supply electrode is not in contact with the conductive surface of the first jaw member.

A surgical bed includes: a table on which a body part of a subject is placed; a leg holder configured to hold a leg part of the subject; a support member configured to connect the table and the leg holder to each other, and configured to adjustably support a positional relationship between the leg holder and the table; and a processor configured to derive the positional relationship between the leg holder and the table.

Certain aspects relate to systems and techniques for an input device for controlling a robotic surgical tool. The input device can include a first pair of opposing links and a second pair of opposing links. The first pair of opposing links and second pair of opposing links can be arranged radially symmetrically. The input device can be configured to control operation of the robotic surgical tool.

Certain aspects relate to systems and techniques for an input device for controlling operation of a surgical tool. The input device includes a first set of one or more input objects for receiving an input of a first type associated with the operation of the surgical tool, and a second set of one or more input objects for receiving an input of a second type associated with the operation of the surgical tool. The input device also includes a Hall effect sensor for detecting a magnetic field based on the first set of one or more magnets and the second set of one or more magnets. A medical system including the input device and a method of using the input device for operating a surgical tool are also disclosed.

A robotically-assisted surgical device assists endoscopic surgery by a surgical robot. The robotically-assisted surgical device includes a processor. The processor is configured to derive a positional relationship between the surgical robot and an access platform installed on a subject which is a surgery target and capable of inserting at least two surgical instruments.

A robotically-assisted surgical device assists robotic surgery by a surgical robot. The robotically-assisted surgical device includes a processor. The processor is configured to: acquire 3D data of a subject; acquire a contact position where a surgical instrument provided in the surgical robot is in contact with a soft tissue of the subject; acquire firmness of the contact position of the soft tissue of the subject; and perform registration of a position of the 3D data with a position of the subject recognized by the surgical robot according to deformation of the soft tissue in the 3D data, based on the contact position and the firmness.

Systems and methods for dynamic adjustments based on load inputs for robotic systems are provided. In one aspect, a robotic system includes a first robotic arm having at least one joint, a set of one or more processors, and at least one computer-readable memory in communication with the set of one or more processors and having stored thereon computer-executable instructions. The computer executable instructions cause the one or more processors to determine a first external load threshold for the at least one joint based on a maximum safe load capability of the first robotic arm, and adjust the first external load threshold during a medical procedure.
