Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 4, the technical solution provided by the present invention is:
example 1: a working tip of ultrasonic medical equipment is characterized in that a needle point 11 and a connector 2 are respectively arranged at two ends of the working tip, the needle point 11 and the connector 2 are mutually connected through a connector 12 positioned in the middle, the connector 2 is in an L-shaped bent shape, so that the needle point 11 can conveniently go deep into teeth, the included angle theta formed by bending is 90-180 degrees, and the included angle theta of the embodiment 1 is 120 degrees; the head of the needle tip 11 is exposed, and the other end is embedded into the connecting piece 12, the head of the embedded end is provided with a step 1101 which is convex or concave (the convex step in the embodiment 1) in shape, so as to prevent the needle tip 11 from rotating or falling off in the connecting piece 12; the other end of the connecting piece 12 is connected with the connector 2 in a threaded or snap-in manner (in this embodiment, the connecting piece 1 is in threaded connection). The thread at the other end of the connector 2 is used for connecting with a transducer of ultrasonic medical equipment.
