Definitions

  • This application generally relates to remotely actuated surgical robot systems having robotic telemanipulators.
  • Open surgery is still the preferred method for many surgical procedures. It has been used by the medical community for many decades and typically required making long incisions in the abdomen or other area of the body, through which traditional surgical tools are inserted. Due to such incisions, this extremely invasive approach results in substantial blood loss during surgery and, typically, long and painful recuperation periods in a hospital setting.
  • Laparoscopy a minimally invasive technique, was developed to overcome some of the disadvantages of open surgery. Instead of large through-wall incisions, several small openings are made in the patient through which long and thin surgical instruments and endoscopic cameras are inserted.
  • the minimally invasive nature of laparoscopic procedures reduces blood loss and pain and shortens hospital stays. When performed by experienced surgeons, a laparoscopic technique can attain clinical outcomes similar to open surgery.
  • laparoscopy requires a high degree of skill to successfully manipulate the rigid and long instrumentation used in such procedures.
  • the entry incision acts as a point of rotation, decreasing the freedom for positioning and orientating the instruments inside the patient.
  • the movements of the surgeon’s hand about this incision point are inverted and scaled-up relative to the instrument tip (“fulcrum effect”), which reduces dexterity and sensitivity and magnifies any tremors of the surgeon’s hands.
  • the long and straight instruments force the surgeon to work in an uncomfortable posture for hands, arms and body, which can be tremendously tiring during a prolonged procedure.
  • robotic surgery still involves several drawbacks.
  • One major disadvantage of previously-known robotic surgical systems relates to the extremely high complexity of such systems, which contain four to five robotic arms to replace the hands of both the surgeon and the assistant, integrated endoscopic imaging systems, as well as the ability to perform remote surgery, leading to huge capital costs for acquisition and maintenance, and limiting the affordably for the majority of surgical departments worldwide.
  • Another drawback of these systems is the bulkiness of previously-known surgical robots, which compete for precious space within the operating room environment and significantly increasing preparation time. Access to the patient thus may be impaired, which raises safety concerns.
  • the da Vinci® surgical systems (available by Intuitive Surgical, Inc., Sunnyvale, California, USA) is a robotic surgical system for allowing performance of remote laparoscopy by a surgeon.
  • the da Vinci® surgical systems are very complex robotic systems, with each system costing around $2,000,000 per robot, $150,000 per year for servicing, and $2,000 per surgery for surgical instruments.
  • the da Vinci® surgical system also requires a lot of space in the operating room, making it hard to move around to a desired location within the operating room, and difficult to switch between forward and reverse surgical workspaces (also known as multi-quadrant surgery).
  • Publication No. 2010/0011900 to Burbank each discloses a robotic teleoperated surgical instrument designed to replicate a surgeon’s hand movements inside the patient’s body.
  • the instrument enables the performance of remote laparoscopy, in which the surgeon, seated at a console and manipulating two joysticks, performs the operation through several small incisions.
  • Those systems do not have autonomy or artificial intelligence, being essentially a sophisticated tool that is fully controlled by the surgeon.
  • the control commands are transmitted between the robotic master and robotic slave by a complex computer-controlled mechatronic system, which is extremely costly to produce and maintain and requires considerable training for the hospital staff.
  • W02013/014621 to Beira describes a mechanical teleoperated device for remote manipulation which comprises master-slave configuration including a slave unit driven by a kinematically equivalent master unit, such that each part of the slave unit mimics the movement of a corresponding part of the master unit.
  • a typical master-slave telemanipulator provides movement in seven degrees-of- freedom.
  • these degrees of freedom include three translational macro movements, e.g., inward/outward, upward/downward, and left/right degrees-of-freedoms, and four micro movements including one rotational degree-of-freedom, e.g., pronosupination, two articulation degrees-of-freedom, e.g., yaw and pitch, and one actuation degree-of-freedom, e.g., open/close.
  • rotational degree-of-freedom e.g., pronosupination
  • two articulation degrees-of-freedom e.g., yaw and pitch
  • one actuation degree-of-freedom e.g., open/close.
  • the routing of the articulation and actuation degrees-of-freedom cables through mechanical telemanipulators may limit the dexterity of the angular range of the various joints of the telemanipulator link-and-joint structure. This in turn limits the available surgical volume of the instruments accessible within the patient.
  • inertia of the telemanipulators also may be disturbing and result in over- shoot of the target and fatigue of the surgeon’s hand. Part of this mass can be attributed to parts and components required to route the actuation and articulation degrees-of-freedom.
  • the present invention overcomes the drawbacks of previously-known systems by providing remotely actuated surgical robot systems having robotic telemanipulators that are preferably well adapted for use by the surgeon, seamlessly integrateable into the operation room, allow for a surgeon to work between the robot and the patient throughout a surgery in a sterile manner, are relatively low cost, and/or permit integrated laparoscopy.

  • the translational macro movements applied at handle 1213 will be replicated by the end-effector of translational instrument interface 1214 in three degrees-of-freedom, e.g., inward/outward, upward/downward, and left/right, due to mechanical constraint 1213.

  • a master telemanipulator of master console 20' includes a base portion having telescoping bases 1008 and 1009 for adjusting the vertical height of the master telemanipulator, and base cap 1010 fixed atop telescoping bases 1008 and 1009 and rotatably coupled to link 26 via joint 25.

As shown in FIG. 43, none of links 1014 or 1016 passes through link 1012. Instead, once the virtual stationary point, e.g., remote center-of-motion, is set by the control system as described above with reference to FIG. 40C-40E, movements applied to the master telemanipulator by the surgeon will be made by slave links and slave joints of the slave console in a corresponding manner about the virtual stationary point.
  • the virtual stationary point e.g., remote center-of-motion
  • master console 20 permits the surgeon to approach the handle grip of handle portion 1018 from top-down (instead of bottom-up or horizontally as with other surgical robots).
  • master console 20 shares the same orientation as the surgeon’s arms such that the base of the master arms is positioned on the side of the surgeon’s body, and not in front in the area of the central pillar of master console 20.
  • sterile master arms of master console 20 are positioned further from the ground in this configuration, sterility of master console 20 is better maintained during use of the surgical system.
  • this configuration reduces the depth of the surgeon console, thereby saving valuable operating room floor space.
  • master console 20' may include master arm break release button 1019 and height adjustment button 1020.
  • master arm break release button 1019 will permit the user to readjust the plurality of master links and master joints until the master telemanipulator is in a desired configured for use by the surgeon
  • height adjustment button 1020 will permit the user to adjust the vertical height, e.g., up or down, of the master telemanipulator via telescoping bases 1008 and 1009.

Abstract

L'invention concerne des systèmes robotiques chirurgicaux pour la manipulation à distance comprenant des télémanipulateurs robotisés. L'invention concerne des systèmes robotiques chirurgicaux bien adaptés à une utilisation par le chirurgien, s'intégrant sans discontinuité dans la salle d'opération, qui permettent à un chirurgien de travailler entre le robot et le patient tout au long d'une intervention chirurgicale de manière stérile, et sont relativement peu coûteux, et/ou permettent une laparoscopie intégrée. Le système comprend de préférence une console de commande ayant une pluralité de liaisons principales interconnectées par une pluralité de raccords principaux, et une poignée couplée à la console de commande principale pour le fonctionnement du télémanipulateur. Le système comprend en outre une console esclave fonctionnellement couplée à la console de commande et ayant une pluralité de liaisons esclaves interconnectées par une pluralité de raccords esclaves qui se déplacent en réponse à un mouvement au niveau de la console de commande pour permettre à un effecteur terminal d'effectuer une intervention chirurgicale.
