Abstract
An ergonomically and functionally improved combination nerve root retractor and sucker device, system, and methods of using such a nerve root retractor and sucker are provided. The nerve root retractor and sucker of the current invention having an adjustable geometry nerve root retractor/sucker shaft.
Claims37
A nerve root retractor and sucker comprising:
- a handle having proximal and distal ends,
- a nerve root retractor/sucker shaft having proximal and distal open ends and defining a central passage therebetween, wherein the proximal end of the shaft is connected to the distal end of the handle, and wherein the axis along the distal end of the shaft forms an angle of less than 180 degrees with the axis of the handle;
- a suction source in fluid communication with the distal opening of the shaft, wherein one or both of the handle and shaft define a suction fluid path between the suction source and the distal opening;
- at least one suction control vent disposed along the suction fluid path such that closing the at least one vent increases the level of suction at the distal opening, and such that opening the at least one vent decreases the level of suction at the distal opening;
- and
- a retractor blade disposed at the distal end of the shaft.

A nerve root retractor and sucker comprising:
- a handle having proximal and distal ends,
- a nerve root retractor/sucker shaft having proximal and distal open ends and defining a central passage therebetween, wherein the proximal end of the shaft is connected to the distal end of the handle, and wherein the angle between the shaft and the handle of the axis may be varied along at least one axis;
- a suction source in fluid communication with the distal opening of the shaft, wherein one or both of the handle and shaft define a suction fluid path between the suction source and the distal opening;
- at least one suction control vent disposed along the suction fluid path such that closing the at least one vent increases the level of suction at the distal opening, and such that opening the at least one vent decreases the level of suction at the distal opening;
- and
- a retractor blade disposed at the distal end of the shaft.
3 more elements
A nerve root retractor and sucker system comprising:
- a handle having proximal and distal ends,
- a plurality of nerve root retractor/sucker shafts having proximal and distal open ends and defining a central passage therebetween, wherein the proximal end of each shaft may be detachably connected to the distal end of the handle, and wherein the axis along the distal end of each of the shafts forms an angle of less than 180 degrees with the axis of the handle and has a length of between about 80 and 220 mm;
- a suction source in fluid communication with the distal opening of the attached shaft, wherein one or both of the handle and shaft define a suction fluid path between the suction source and the distal opening;
- at least one suction control vent disposed along the suction fluid path such that closing the at least one vent increases the level of suction at the distal opening, and such that opening the at least one vent decreases the level of suction at the distal opening;
- and
- a retractor blade disposed at the distal end of each of the plurality of shafts,
- wherein at least one of the angle and length of at least two of the plurality of shafts are different.
