Electric osteotome

Abstract

The invention relates to an electric osteotome and belongs to the technical field of artificial joints, the electric osteotome comprises a power assembly, a sliding cylinder and an osteotome, the end, away from a tool bit, of the osteotome is installed on the sliding cylinder, the end, away from the osteotome, of the sliding cylinder is slidably connected with the power assembly, and the sliding direction is arranged in the length direction of the osteotome; the power assembly is used for providing power for sliding of the sliding cylinder. The osteotomy device has the effect of accurate osteotomy.

Description

technical field [0001] The present application relates to the technical field of artificial joints, and in particular, to an electric bone knife. Background technique [0002] Bone spurs are medically called osteophytes, also known as hyperostosis, which are new bones produced by the excessive proliferation of perichondrium after the destruction of cartilage. After ossification, osteophytes are formed. A kind of compensatory reaction, the hyperplasia of osteophytes usually exists around both ends of the bone, but projected on a plane X-ray film, it may only appear as thick spines with a wide base and a thin tip, so it is necessary to remove the osteophytes. For the removal of osteophytes, bone knives are often used. The commonly used bone knives are artificial bone knives. That is, the doctor holds the handle of the bone knife and taps the tail of the bone knife, and the force reaches the head of the bone knife through conduction, thereby completing the removal of osteophyte...

AI Technical Summary

Problems solved by technology

[0003] During the research improvement, the researchers found that when removing osteophytes, the doctor needs to continuously beat the bone knife, which is time-consuming and laborious, and may cause the bone knife to be skewed, and there is a defect of inaccurate osteotomy
