Abstract
A surgical instrument system for use in surgical procedures is disclosed. The surgical instrument system includes a guide assembly, a surgical tip assembly, and a drive unit. The guide assembly includes an elongated portion having a central axis of rotation, and a distal end that is positioned a radial distance away from the central axis. The surgical tip assembly may be attached to the guide assembly. The drive unit is coupled to the guide assembly for rotating the guide assembly and thereby rotating the surgical tip with respect to the central axis.

7. A surgical instrument system for use in surgical procedures, said surgical instrument system including:
-
a guide assembly that may be positioned in a surgical environment, said guide assembly including a proximal end and a distal end, and including a central opening along a longitudinal length of said guide assembly, said guide assembly being adapted for insertion into a patient and being adapted for rotation about a longitudinal axis of said guide assembly when inserted into the patient;
an end effector that may used in surgical procedures, and may be received by said proximal end of said guide assembly, passed through said central opening, and to said distal end of said guide assembly within a patient; and
a drive unit coupled to said surgical tip assembly for manipulating said surgical tip assembly within the patient. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A surgical instrument for use in surgical procedures, said surgical instrument comprising:
-
a distal end that is adapted to be inserted into a patient during surgery;
a proximal end that is adapted to remain outside of the patient during surgery;
a plurality of link members coupled to one another via a plurality of joints that are interposed between adjacent link members, some of said link members being located at the distal end of the instrument, said instrument providing at least five degrees of freedom of movement of said distal portion of said instrument inside of the patient; and
drive means for effecting movement of said plurality of said link members about said plurality of joints.

21. A surgical instrument for use in surgical procedures, said surgical instrument including a proximal end and a distal end and comprising:
-
an end effector at the distal end of said surgical instrument, said end effector for use within a patient'"'"'s body during surgical procedures;
a flexible intermediate portion extending from said distal end to said proximal end; and
a coupling assembly at the proximal end for securing said surgical instrument to an actuation unit within a surgical environment.

22. A method of manipulating a surgical instrument, said method comprising the steps of:
-
inserting a distal portion of a surgical guide assembly into a patient;
removably securing the surgical guide assembly in a surgical environment;
inserting a surgical tip assembly through the guide assembly; and
actuating a drive unit to effect the manipulating the position of the surgical tip assembly within the patient. - View Dependent Claims (23, 24, 25)
