Abstract
A rotatable surgical instrument having a protective hood with articulating bendable distal end is provided to improve and enable various orthopedic surgical procedures such as arthroscopy. The protective hood surrounds the surgical tool bit exposing only a portion of the tool bit for removing bone or soft tissue material and protects the nerve from the surgical tool bit. The protective hood can be controllably rotated from the instrument's hand piece to control the orientation of the attack angle of the surgical tool bit. Additionally, the bending of the distal end of the instrument can be controlled from the hand piece.
Claims22
A surgical instrument comprising:
- a hand piece having a distal end and a proximal end;
- a shaft portion extending from the distal end of the hand piece and having a distal end and a proximal end;
- a drive shaft disposed for rotation within the shaft portion, the drive shaft having a distal end and a proximal end thereof;
- a surgical tool bit connected to the distal end of the drive shaft;
- a protective hood connected to the distal end of the shaft portion, wherein the surgical tool bit resides within the protective hood, partially exposed, and the protective hood is rotatable relative to the surgical tool bit exposing a different portion of the surgical tool bit;
- and
- said hand piece including a first control member, said first control member operably connected to the proximal end of the shaft portion and manipulation of the first control member controls the rotation of the protective hood relative to the hand piece and the drive shaft via the shaft portion.
A surgical instrument comprising:
- a hand piece having a distal end and a proximal end;
- a power drive mechanism provided with the hand piece;
- a shaft portion extending from the distal end of the hand piece and having a distal end and a proximal end;
- a drive shaft disposed for rotation within the shaft portion, the drive shaft having a distal end and a proximal end thereof, wherein the proximal end is connected to the power drive mechanism;
- a surgical tool bit connected to the distal end of the drive shaft;
- a protective hood attached to the distal end of the shaft portion, wherein the surgical tool bit resides within the protective hood, partially exposed, and the protective hood is rotatable relative to the surgical tool bit exposing a different portion of the surgical tool bit;
- and
- said hand piece including a first control member, said first control member operably connected to the proximal end of the shaft portion and manipulation of the first control member controls the rotation of the protective hood relative to the hand piece and the drive shaft via the shaft portion.
