Abstract: A bone material removal device, including a tubular element comprising a proximal end and a distal end, a shaft received within the tubular element and comprising a proximal end and a distal end, a cutting tooth movably coupled to the distal end of the shaft and a shaft displacement actuator at the proximal end of the tubular element rotatably coupled to the shaft, wherein at least partial rotation of the actuator in a first direction brings the cutting tooth to travel from a closed retracted position to an open extended position.

Abstract: A bone drill guiding device including a drill entry part comprising a cannula having a distal end portion and sized to receive a bone drill, a drill exit part comprising a fixation tip portion and a coupling that rigidly couples the drill entry part and the drill exit part so that longitudinal axes of the cannula distal portion and the fixation tip portion are arranged on a single mutual axis. In some embodiments, the coupling is a linear sliding coupling that parallels the single mutual axis.

Abstract: An arthroscopic tool for labrum repair procedure, including: a cannulated working channel having a proximal end and a distal end; and a holding element adapted to be attached to the proximal end of the working channel for supporting a labrum during an arthroscopic labrum repair procedure.

Abstract: A bone removal device, including an elongated shaft having a longitudinal axis, a distal end and a proximal end; a movable bone borer movably coupled to the distal end of the elongated shaft, wherein the movable bone borer is configured to rotate around the longitudinal axis; and a rotatable bone borer adjuster mounted on a proximal side of the elongated shaft and to the movable bone borer, wherein the adjuster is configured to rotate around an axis which is different from a rotation axis of the movable bone borer.

Abstract: A tool has a handle and an elongate shaft that extends distally from the handle. A distal portion of the shaft is inserted into a subject during a surgical procedure. An optical fiber delivers laser energy to a tip at the distal portion of the shaft. The tip includes a mechanical cutting mechanism including a moving part that absorbs the laser energy, thermally conducts the absorbed energy to tissue that is disposed between the moving part and another part, and moves with respect to the other part in order to cut tissue that is disposed between the parts using a mechanical force that is lower than a mechanical force that would be required to cut the tissue in the absence of the laser energy. Other embodiments are also described.

Abstract: A drill device including a shaft having a proximal end and a distal end, one or more first reaming heads configured to be positioned along the shaft adjacent the distal end and one or more second reaming heads configured to be positioned along the shaft at a location axially proximally spaced from the first reaming head.

Abstract: A bone removal device, including: an elongated shaft having a longitudinal axis, a distal end and a proximal end; a bone borer having a distal drilling tip configured to drill into a bone tissue and at least one proximal reamer, wherein the bone borer is movably coupled to a distal end of the elongated shaft, wherein the bone borer is configured to move between a drilling state in which the drilling tip is placed in contact with bone tissue, and reaming states in which the at least one proximal reamer is placed in contact with the bone tissue.
