US 11,241,291 B2 · Modular robotic system for driving movement of surgical tools

Abstract

A modular robotic surgical system includes one or more tool-receiver units arranged as separate units, each tool-receiver unit operable to move a first elongate surgical tool received therein. The device also includes a base comprising one or more motors, the base operable to move a second elongate surgical tool attached to the base or received therein, the base serving as a mounting for the one or more tool-receiver units, each of the tool-receiver units is independently and interchangeably attachable to the base via a mechanical coupling interface which transfers one or more of: driving force for driving movement of the first elongate surgical tool received within the unit; electrical power supply to one or more components of the unit which drive movement of the first elongate surgical tool received within the unit; and data for controlling movement of the first elongate surgical tool received within the unit.

Dependent claims

A modular robotic surgical system for manipulation of at least first and second elongate surgical tools which are flexible and configured for insertion into a body lumen, the system comprising:

one or more tool-receiver units arranged as separate units, each tool-receiver unit operable to move said first elongate surgical tool when said first elongate surgical tool is partially received therein, such that said first elongate surgical tool is axially moveable within a housing of said tool-receiver unit;
a base comprising one or more motors, the base operable to move said second elongate surgical tool when said second elongate surgical tool is partially received therein, the base serving as a mounting for said one or more tool-receiver units, such that said second elongate surgical tool is axially moveable within a housing of said base;
wherein each of said tool-receiver units is independently and interchangeably attachable to said base via a mechanical coupling interface which transfers one or more of:
driving force for driving movement of said first elongate surgical tool received within said tool-receiver unit;
electrical power supply to one or more components of said tool-receiver unit which drive movement of said first elongate surgical tool received within said tool-receiver unit;
and data for controlling movement of said first elongate surgical tool received within said tool-receiver unit.

3 more elements

A method of assembling and operating a modular robotic surgical system for manipulation of at least first and second elongate surgical tools which are flexible and configured for insertion into a body lumen, the method comprising:

selecting a system configuration according to a surgical procedure to take place;
assembling the system by operably attaching at least one tool-receiver unit configured to receive said first elongate surgical tool onto a base;
said base configured to receive said second elongate surgical tool;
said base comprising at least one motor configured to drive movement of said first and second elongate surgical tools;
wherein said operably attaching comprises mechanically coupling said at least one tool-receiver unit and said base;
positioning the assembled system with respect to a patient;
and
carrying out the surgical procedure by controlling movement of said first and second elongate surgical tools within the body of the patient, said controlling comprising activating said at least one motor of said base;
wherein said first elongate surgical tool is axially moveable within a housing of said tool-receiver unit, and said second elongate surgical tool is axially moveable within a housing of said base.
