Intraarticular drill guide and arthroscopic methods

An intraarticular drill guide comprising:

• an elongated base member having a longitudinal passage therethrough;
• a tip extending from said base member proximate an end of the longitudinal passage;
• a hook having a shaft defining a longitudinal axis alongside said longitudinal passage and adjustably mounted to said base member for reciprocal movement longitudinally with respect to said base member;
• and
• means for axially rotating said shaft about the longitudinal axis to rotate said hook into or out of opposition with said tip.

An intraarticular drill guide comprising:

• a cannulated guide shaft having a distal end, a proximal end, and a longitudinal cannulation between the distal end and the proximal end;
• a sliding shaft defining a longitudinal axis and being mountable on said guide shaft for reciprocal movement longitudinally with respect to said guide shaft and having a distal end extending beyond the distal end of said guide shaft;
• a hook extending from the distal end of said sliding shaft, said hook and sliding shaft being insertable through an arthroscopic portal into a joint;
• and
• a handle attached to the proximal end of said guide shaft including pulling means for pulling said sliding shaft to force said hook toward said cannulated guide shaft;
• said sliding shaft being rotatable about the longitudinal axis for swinging said hook into or out of opposition with the distal end of said guide shaft.

A method for arthroscopic drilling through a bone comprising the steps of:

• forming an arthroscopic portal;
• providing a cannulated guide shaft;
• providing a sliding shaft alongside said guide shaft, the sliding shaft defining a longitudinal axis and having a hook at its distal end;
• passing said cannulated guide shaft through the portal and against one side of the bone;
• inserting said sliding shaft into the joint;
• rotating said sliding shaft independent of said guide shaft about the longitudinal axis, so as to move an end top of said hook into axial alignment with said cannulated guide shaft and against an opposite side of the bone;
• pulling on the sliding shaft back toward the cannulated guide shaft to hold the bone between the hook and the cannulated guide shaft;
• and
• operating a drill through the cannulated guide shaft.

• a hook extending from the distal end of said sliding shaft, said hook and sliding shaft being insertable through an arthroscopic portal into a joint;
• and
• a handle attached to the proximal end of said guide shaft including pulling means which upon being pushed in a first direction toward the distal end of said guide shaft pulls and sliding shaft in an opposite direction to force said hook toward the distal end of said cannulated guide shaft said sliding shaft being rotatable about the longitudinal axis for swinging said hook into and out of opposition with the distal end of the guide shaft.

A method for arthroscopic drilling through a bone comprising the steps of:

• forming an arthroscopic portal;
• providing a sliding shaft having a hook at its distal end;
• providing a cannulated guide shaft having at its proximal end means for reciprocally moving said sliding shaft along said guide shaft;
• passing said cannulated guide shaft and said sliding shaft through the portal;
• locating said cannulated guide shaft against the bone;
• rotating said sliding shaft independent of said guide shaft about the longitudinal axis, so as to move an end tip of said hook into axial alignment with said cannulated guide shaft and against an opposite side of bone;
• pushing on the moving means in one direction so as to pull the sliding shaft in an opposite direction back toward said cannulated guide shaft to hold the bone between the hook and said cannulated guide shaft;
• and
• operating a drill through the cannulated guide shaft.
