摘要:
A surgical instrument (10) has a housing (12) which contains a motor (14) that drives a spindle (104). A tool bit (20) is attached to the motor by a holder (100) that includes a body with a first end portion connected to the spindle (104), a central portion having an aperture (105) through which a shaft of the tool bit (20) passes into the cavity (114). A pair of lock pawls (118) are pivotally mounted in the cavity (114) with each one having a first tab (126) that enters a slot (158) in the shaft when the lock pawls (118) are in a first position to hold the tool bit (20) in the instrument (10). The first tabs (126) retract from the slot (158) when the lock pawls (118) are in a second position for changing the tool bit (20). A ring (134) extends around the body and pivots the lock pawls (118) between the first and second positions, and a lever (138) is pivotally coupled to the housing to move the ring (134).
