Abstract

The invention relates to a piezosurgery machine working tip, which consists of a working tip tool bit (1), a working tip head part (2), a working tip neck part (3) and a working tip connection part (5), wherein the working tip tool bit (1) is of a flat-spoon shaped plane; one surface is extruded in a wave shape; and the other surface is a smooth surface. According to the piezosurgery machine working tip disclosed by the invention, the edge of an orthopedic surgery can be subjected to bone surface expansion and grinding. The piezosurgery machine working tip has the advantages of convenience in use and simpleness in operation, and meanwhile, damage on an adjacent bone surface is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a working tip of an ultrasonic bone knife machine. Background technique [0002] In bone cutting surgery, the bone is cut open to perform the surgery. The ultrasonic bone knife machine is to achieve the purpose of bone cutting through ultrasonic vibration of the knife head. An ultrasonic transducer is installed on the ultrasonic bone knife machine, as an ultrasonic oscillation source, by converting electrical energy into ultrasonic oscillation, it drives the working tip installed on the transducer to work. According to the different cutting methods and methods required by the operation, it is necessary to design the working tip into different shapes. Publication No. EP2233085A1 (Surgical Instrument for Cutting Bone) European Patent, Publication No. US8002783B2 (Surgical Device For Bone Surgery Surgical Equipment for Orthopedic Surgery) discloses a variety of different shapes and structures. ...
