Abstract
A method and apparatus for implanting a prosthetic through a less invasive procedure. Generally, an instrument is provided to allow for a torque transfer along a non-linear line. Therefore, an incline can be provided without obstructing the view of a user using the instrument.
Claims28
An instrument for implanting a prosthetic into a selected portion of a body, comprising:
- a prosthetic engaging portion operable to selectively engage the prosthetic and extending along a first axis;
- a graspable portion extending from said prosthetic engaging portion;
- and
- a rotatable torque transfer system to transfer rotational torque from a second axis to said first axis, said torque transfer system rotates independently of said graspable portion;
- wherein said first axis intersects said second axis;
- wherein said torque transfer system includes at least a first portion extending along said first axis and extending from said prosthetic engaging portion and a second portion extending along said second axis;
- wherein said prosthetic engaging portion is operable to at least one of engage and disengage the prosthetic via said torque transfer system.
4 more elements
An apparatus for providing an implant to a selected area of a body, comprising:
- a graspable portion able to transfer a force to an implant engaging portion along a first axis;
- an intermediate portion interconnecting said graspable portion and said implant engaging portion, wherein at least a portion of said intermediate portion is spaced a distance from said first axis;
- an angled portion of said intermediate portion extends along a second axis that intersects said first axis;
- a torque transfer system at least partially housed in said angled portion that rotates independently of said angled portion and transfers rotational torque to said implant engaging portion;
- wherein said torque transfer system is operable to torque said implant engaging portion to at least one of engage and disengage the implant.
2 more elements
An apparatus for implanting a prosthetic into a selected portion of a body comprising:
- a prosthetic holding portion extending along a first axis, said prosthetic holding portion including an outer housing;
- a graspable portion extending along said first axis;
- a clearance portion between said prosthetic holding portion and said graspable portion, said clearance portion extending along a second axis that is offset from said first axis to provide a user of said apparatus with a clear view of said prosthetic holding portion;
- and
- a rotational torque transfer system including a torque transferring portion at said prosthetic holding portion that rotates independently of said outer housing and a driving portion extending from said prosthetic holding portion to said clearance portion, said torque transferring portion is angled relative to said driving portion;
- wherein said torque transfer system applies rotational torque to said implant to engage and disengage said implant.
