Abstract

A surgical instrument system having an instrument member or shaft with a distal portion positionable through an incision of a patient to an internal site and for operation by a surgeon from outside the patient. A tool is carried at the distal end of the instrument shaft controlled by the surgeon in performing a procedure at an operative site of the patient. At least first and second turnable members are spacedly disposed along the instrument shaft distal portion, both disposed within the internal site, and each controlled from outside the patient for providing at least respective first and second degrees of freedom of control of the tool. The turnable members may be either a pivot joint or a bendable section.

Claims

1. A surgical instrument system comprising:

an instrument member having a distal portion positionable through an incision of a patient to an internal site and for operation by a surgeon from outside the patient;

a tool carried at the distal end of said instrument member controlled by the surgeon in performing a procedure at an operative site of the patient; and

at least first and second turnable members spacedly disposed along said instrument member distal portion, both disposed within said internal site, and each controlled from outside the patient and for providing at least respective first and second degrees of freedom of control of said tool.

2. The surgical instrument system of claim 1 wherein each turnable member comprises a pivot connection.

3. The surgical instrument system of claim 1 wherein each turnable member comprises a bendable section.

4. The surgical instrument system of claim 1 including a user interface operable by a surgeon and including an input device manipulable by the surgeon to control the turnable members and tool.

5. A surgical instrument system in which a surgical instrument is robotically operated by a medical practitioner from a master station area where an input device is manipulated by the medical practitioner in order to perform a surgical procedure on a patient, said surgical instrument comprising:

an instrument shaft having a proximal portion disposed for positioning at a position outside the patient, and a distal portion positionable through an incision of a patient to an internal site;

an end effector carried at the distal end of said instrument shaft and remotely controlled by the medical practitioner in performing the surgical procedure; and

at least first and second turnable members spacedly disposed along said instrument member distal portion, proximal of said end effector;

both of said turnable members being disposed within said internal site, and each controlled from said master station for providing at least respective first and second degrees of freedom of control of said end effector.

6. The surgical instrument system of claim 5 wherein said instrument shaft is supported by a slider that is controllable to provide at least linear translation of said instrument shaft.

7. The surgical instrument system of claim 5 wherein said turnable members comprise a pivot connection.

8. The surgical instrument system of claim 5 wherein said instrument shaft is supported by a slider that is controllable to provide at least rotation of said instrument shaft.

9. The surgical instrument system of claim 5 wherein each turnable member comprises a bendable section.

10. The surgical instrument system of claim 5 further including a wrist member between said end effector and said turnable members.

11. The surgical instrument system of claim 10 wherein said wrist member comprises a pivot connection.

12. The surgical instrument system of claim 10 wherein said wrist member comprises a bendable section.

13. The surgical instrument system of claim 5 wherein at least one of said turnable members comprises a bendable section.

14. The surgical instrument system of claim 13 wherein said bendable section has one degree of freedom of motion.

15. The surgical instrument system of claim 13 wherein said bendable section has two degrees of freedom of motion.

16. The surgical instrument system of claim 15 wherein said degree of freedom are orthogonal to each other.

17. The surgical instrument system of claim 5 further including a third turnable member proximal of said end effector and internal of the incision.

18. The surgical instrument system of claim 5 wherein all degrees of freedom are internal of the incision.
