A detachable dental handpiece with anti-loosening safety device

Abstract

The invention discloses a detachable dental handpiece with an anti-loosening safety device, which comprises a machine body, a connecting seat and a machine head. The machine head comprises a machine head shell and a split seat. The machine body comprises a machine body shell, a hollow mounting seat, a speed reducer and a ejector rod. The connecting seat is fixed on the speed reducer, and the speedreducer is fixed on the hollow mounting seat. The shell of the machine body sleeves the hollow mounting seat and the outer wall of the reducer. The lower part of the hollow mounting seat and the connecting seat are provided with sockets. The ejector rod is provided with a ejector rod radial boss, the bottom end of the ejector rod is inserted in the jack of the hollow mounting seat and protrudes out of the hollow mounting seat, the ejector rod radial boss abuts on the jack, and the top end of the ejector rod is inserted in the jack of the connecting seat. As that anti-loosening structure and the detachable structure are arranged, the ejector rod extends into the limit slot when the dental handpiece is operated, the ejector rod is difficult to slide out, the connection part is loosened dueto the high-speed rotation, the safety accident is prevented, and the postoperative disassembly of the main component is convenient for more effective cleaning and maintenance.

Description

technical field [0001] The invention relates to a medical device technology, in particular to a detachable dental handpiece with an anti-loosening safety device. Background technique [0002] Dental handpiece is a commonly used medical device for oral treatment. Through high-speed rotation and different shapes of burs, it can position, drill, expand or even cut oral hard tissues. Blood, saliva, etc. are usually produced during oral surgery on patients. Infections penetrate into the interior of the mobile phone, and the parts are difficult to disassemble and clean. Long-term accumulation will affect the service life of the mobile phone, and it is easy to cause cross-infection. [0003] Existing dental handpieces are composed of a fuselage and a handpiece. The fuselage and the handpiece are detachably installed. However, the existing detachable method adopts threaded connection. However, due to the high-speed rotation and vibration during the working process, it is easy to cau...
