Surgical rotational tool driver and method

A method of operating a surgical rotational tool driver, the method comprising:

• connecting one or more connection features of a head part of a driveline of a surgical rotational tool driver to a connection member of a surgical rotational tool, the surgical rotational tool driver comprising:
• a substantially hollow shaft having a proximal end and a distal end;
• the driveline extending within the hollow shaft, the driveline having:
• a proximal end connectable to a rotational power tool for applying torque through the driveline;
• and
• said head part extending distally from the distal end of the shaft, the head part having an axis of rotation for rotation of the surgical rotational tool on rotation of the driveline, the connection features of the head part comprising:
• a housing;
• a pair of jaw members, each jaw member including a pair of jaws for receiving the connection member of the surgical rotational tool, wherein each jaw member is pivotally mounted on the housing for rotation about an axis substantially perpendicular to the axis of rotation of the head part between:
• a first position for receipt of the connection member within the jaws of each jaw member;
• and
• a second position for retaining the connection member within the jaws of each jaw member to prevent removal of the surgical rotation tool from the surgical rotational tool driver;
• and
• a locking mechanism comprising:
• a pair of ramps for engaging with a respective catch of each jaw member to lock the jaw members in the second position, and
• a release member slideably moveable within the housing to release the ramps of the locking mechanism from the respective catches of the jaw members to allow the jaw members to return to the first position for removal of the surgical rotational tool from the surgical rotational tool driver;
• riding the catch of each jaw member along a respective ramped surface extending laterally from the release member as the jaw members pivot from the first position to the second position and engaging the catches of the jaw members with retaining surfaces located at an end of the respective ramped surfaces when they reach the end of the ramped surfaces, to lock the jaw members in the second position;
• operating the release mechanism by sliding the release member within the housing;
• and
• removing the surgical rotational tool from the surgical rotational tool driver.
