Described herein are systems and apparatus of surgical instruments engineered for integration with robotic surgical systems to enhance precision in surgical procedures. Also described herein are methods of using such surgical instruments in performing surgical procedures. The use of such surgical instruments reduce complications arising from misalignment during surgery. The disclosed technology assists in stages of a surgical procedure that require a precise trajectory to be followed. Surgical instrument guides are attached to a universal surgical instrument guide, which is engineered to attach directly or indirectly with a robotic arm of a robotic surgical system. Surgical instruments can then be precisely guided along an axis defined by the universal surgical instrument guide. Individual instruments are easily inserted and removed from the channel of the universal surgical instrument guide, thus allowing a range of instruments to be used throughout a procedure while maintaining the surgical trajectory.

For surgical and/or medical instruments, a smart handle for easily and more accurately manipulating an elongated functional system inside the body of a subject, including a handle body extending along a longitudinal axis having a first electrical interface including at least two electrical connectors, a second electrical interface with at least two circular conductive elements and a chamber for receiving a power supply; the power supply being connected to one of the electrical interfaces, at least one first external command being arranged on the outer surface of the handle body, and when activated, the first external command allows to flow an electrical current through the electrical connectors; the electrical connectors being maintained in contact with the other electrical interface by a spring force, the electrical connectors including at their distal end a round tip for ensuring a permanent contact between the electrical connectors and the circular conductive elements during rotation.

A system for delivery of cardiac implants includes a catheter having a handle assembly including a cable control assembly. The handle assembly further includes a tubular body assembly extending distally from the handle assembly and deflectable by operation of the cable control assembly. The system also includes a robot having a linear displacement platform and a carriage coupled to the linear displacement platform. The carriage includes a drive motor assembly and is at least one of linearly displaceable along the linear displacement platform and rotatable relative to the linear displacement platform. The handle assembly is coupled to the carriage such that the cable control assembly interfaces with the drive motor assembly of the carriage to facilitate operation of the cable control assembly by the robot.

Catheter device and driving system configured to navigate the catheter through complex narrow tissue openings such as lung bronchi pathway openings of 3 millimeters or less. The device comprises a proximal catheter portion containing a hollow torque shaft, with a distal catheter portion connected to the proximal portion connected to this torque shaft. The distal position of the catheter is controlled by at least one steering cable/tensioning cable arrangement. The system uses processor-controlled actuators that simultaneously rotate the torque shaft and the at least one steering cable/tensioning cable in a 1:1 relationship, while also actuating the steering cable. The catheter is tipped by a tool plate, which can be equipped with various sensors and other instruments and connected to the outside via other conduits.

System and method for using processor-controlled actuators to drive multi-stage catheter devices configured to navigate through complex narrow tissue openings such as lung bronchi pathway openings. The device comprises a proximal catheter portion containing a hollow torque shaft, with a distal catheter portion connected to the proximal portion by a rotatable coupler connected to this hollow shaft. The distal position of the proximal catheter can be controlled by independently controlled proximal stage steering cables positioned outside of the shaft, and the shaft itself can be used to rotate the distal catheter about the rotatable coupler. The position of the distal end of the distal catheter can be further controlled by distal stage steering cables positioned inside of the hollow shaft. The device is tipped by a tool plate, which can be equipped with various sensors and other instruments, connected to the outside via other conduits.

Catheter device and driving system configured to navigate the catheter through complex narrow tissue openings such as lung bronchi pathway openings of 3 millimeters or less. The device comprises a proximal catheter portion containing a hollow torque shaft, with a distal catheter portion connected to the proximal portion by an isolation transition coupler connected to this torque shaft. The distal position of the catheter is controlled by at least one steering cable/isolation coil arrangement. The system uses processor-controlled actuators that simultaneously rotate the torque shaft and the at least one steering cable/isolation coil in a 1:1 relationship, while also actuating the steering cable. The catheter is tipped by a tool plate, which can be equipped with various sensors and other instruments, connected to the outside via other conduits.

The disclosure relates to a guide wire friction feedback device and method for interventional surgical robot. The friction feedback device includes two sets of driving end parts, driven end parts and clamping parts symmetrically arranged along the guide wire. The structure of the friction feedback device is relatively simple, compact and stable. When the clamping part is subjected to the force in the clamping direction of the guide wire, the force is transmitted to the right-angle connecting plate through the U-shaped slot connector, the first slider and the first micro linear guide. The high precision load cell only measures the axial force of the guide wire, that is, the push-pull force felt by the high precision load cell (that is, the friction on the guide wire), so as to judge the force change of the axial friction of the guide wire.

A surgical system (200) includes a surgical instrument (260) that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument (260) is coupled to motors in a surgical instrument manipulator assembly (240) via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly (240) have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly (240). From the drive output disk (545) in the surgical instrument manipulator assembly to the driven disk (964) of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.
