Rotational endoscopic mechanism with jointed drive mechanism
First Claim
1. An endoscopic mechanism comprising:
- an endoscopic portion containing an outer tube which defines a longitudinal axis of said tube and through which may be operated an drive rod;
a drive rod contained within said outer tube, said drive rod containing a proximal end connected to a handle, and a distal end connected to an end effector portion;
a trigger connected to said drive rod said trigger capable of operating said end effector portion; and
wherein said end effector portion is capable of being angulated up to 90°
with said outer tube; and
wherein said end effector portion is connected to an articulation tube concentric to said outer tube, and said articulation tube capable of moving said end effector portion with respect to said longitudinal axis.

Abstract
Described herein is an endoscopic instrument such as a dissector, scissor or grasper in which there is provided a shaft which defines a longitudinal axis of the instrument. This shaft is able to rotate about the handle portion of the instrument. This mechanism also provides for articulation of the end effectors with respect to the longitudinal axis of the shaft. This articulation is accomplished by causing angulation of the end effector with respect to the shaft. Because driving the cable is accomplished around any such angle, the end effectors continue to be able to operate. There is disclosed herein a locking mechanism which allows the rotational aspect of the device to operate to rotate the entire articulating mechanism.

8. A mechanism for performing endoscopic procedures comprising:
-
an outer tube having a hollow interior and defining a longitudinal axis; an end effector portion connected to said hollow outer tube, said end effector portion pivotable about said tube; an articulation mechanism connected to said end effector portion, said articulation mechanism reciprocable with respect to said longitudinal axis; and a handle portion attached to said articulation mechanism, said handle portion containing an articulation knob capable of reciprocating said articulation tube; and wherein said articulation knob contains a helical interior, and said articulation tube is connected to a winged nut within said helical interior, such that rotation of said articulation knob causes said winged nut to reciprocate said articulation tube with respect to said longitudinal axis. - View Dependent Claims (9)

10. The handle of an endoscopic instrument containing a shaft and wherein said handle is connected to one knob capable of causing said instrument to perform one function, and a second knob capable of causing said instrument of performing a second function, said handle further containing a spring mechanism separating said knobs;
- and
wherein said second knob requires a force to be applied by the user to overcome the spring force of said spring force causes engagement of said first knob and said second knob and said engagement of said knobs allows said second knob to cause said second function. - View Dependent Claims (11, 12, 13, 14, 15)
