Abstract: A medical device includes a handle; flexible tubing extending from the handle and having a proximal end fixed to the handle; flexible tip attached to the distal end of the flexible tubing; a tip actuator assembly adjusting the bending plane of the tip relative to the distal end and adjusting the degree of bending of the tip in the bending plane; user operable controls on the handle and moveable in a first, rotational direction relative to the handle and to a tip actuator assembly around an axis causing the tip actuator assembly to adjust the bending plane of the tip substantially and moveable relative to the handle and the tip actuator assembly along a second, substantially linear direction towards and away from the proximal end of the flexible tubing, causing the tip actuator assembly to adjust bending of the tip in the bending plane without adjusting the bending plane.

Abstract: A surgical instrument includes a handle with a main body having a central axis, a lever pivotable around a pivot axis fixed with respect to the main body. The lever includes a finger abutment section including a lower finger rest contacting the ventral sides of a user's first and second fingers during pivoting movement of the finger abutment section towards the central axis, and an upper finger rest contacting the dorsal sides of both the fingers during pivoting movement of the finger abutment section away from the central axis; and a septum fixed to lower and upper finger rests and extending therebetween forming a separate first and second finger receiving portion for respectively receiving a first and a second fingers. The lever pivots around the pivot axis such that during pivoting of the lever, the septum central plane remains substantially coplanar with a plane parallel to the central axis.

Abstract: Disclosed is a surgical instrument with an elongate body with a longitudinal axis having a distal end and a proximal end. The instrument has a pitch capstan having an axis transversely to the longitudinal axis at one end of the elongate body. At least two pairs of cables extend along the elongate body, along the pitch axis to a respective work member to which they are attached. The cables are guided in sliding contact along a slide bearing situated at or near the pitch axis. Also disclosed is a handle for a medical instrument having a hinging connection with the elongate body situated near an inside hand region of the user.
