CHUCK WITH A PUSH BUTTON RELEASE FOR A DENTAL/MEDICAL DEVICE |
摘要 |
A medical/dental device (1) is provided which includes a body (3) having a hollow sleeve (5) and a head (7) at an end of the sleeve. The head defines an upwardly opening chamber (23) which receives a chuck (13). The chuck includes a bur tube (41) which removably receives a medical/dental tool (15) of the latch-type shaft and a push button actuator (95) to release the shaft from the bur tube. The bur tube includes a flexible arm (61) which extends above the bur tube's upper surface and has an inwardly extending finger (71) positioned to engage the groove of the shaft. The push button includes a downwardly extending pedestal (105) which engages the arm to move the arm from a first position in which the groove and the finger create an interference fit to prevent the shaft from being removed from the head to a second position in which the finger is disengaged from the groove to allow removal of the shaft. |
