Abstract

The invention discloses a piezosurgery head. The piezosurgery head comprises a piezosurgery body, a piezosurgery rod and a piezosurgery head tip, one end of the piezosurgery rod is connected with thepiezosurgery head tip, and the other end of the piezosurgery rod is connected with the piezosurgery body. The piezosurgery head is characterized in that the piezosurgery head tip is a column body withthe cross section of a polygonal structure or is of a structure similar to a column body, and the piezosurgery head tip is at least provided with two cutting surfaces with different cutting widths. Aliquid flowing hole is formed in the piezosurgery head. The piezosurgery head tip is provided with a knurling structure, the knurling structure extends in the direction of the piezosurgery rod from the most front end surface of the piezosurgery head tip, and thus the file-type piezosurgery head is formed. The piezosurgery head meets accuracy requirements of doctors to the bone cutting width, cansave required time for replacing piezosurgery heads with different widths and improve the surgery efficiency.

Description

technical field [0001] The invention belongs to the field of surgical instruments, in particular to an ultrasonic osteotome cutter head. Background technique [0002] In orthopedic ultrasonic surgery, doctors use ultrasonic osteotome to cut, grind or shape bones or other organisms and their bionic tissues (such as cartilage and bone cement). [0003] The tip of the current ultrasonic osteotome, that is, the end of the cutter head, only has a single cutting width. When doctors need accurate cutting with a larger width, they can only complete it through multiple reciprocating cuts, or replace the ultrasonic cutter head with different widths. The reciprocating cutting operation makes it difficult for the doctor to accurately grasp the width of the incision, and it takes a long time to replace the ultrasonic cutter head with different widths, which affects the continuity of the doctor's operation and prolongs the operation time to a certain extent. Contents of the invention ...
