Ultrasonic osteotome used under foramen intervertebrale endoscope

Abstract

The invention discloses an ultrasonic osteotome used under a foramen intervertebrale endoscope. The ultrasonic osteotome comprises an osteotome rod, an osteotome head and a crescent groove with cutting teeth and grinding teeth, the osteotome head is arranged at one end of the osteotome rod, the crescent groove is formed in the osteotome head, a first vertical tooth grain is arranged at the inner end of the crescent groove, a second vertical tooth grain is arranged on the side wall of the periphery of the osteotome head, a cutting grain is arranged at the front end, and a joint is arranged at the other end of the osteotome rod. The ultrasonic osteotome has the beneficial effects that by arranging the osteotome head, the crescent groove with the cutting teeth and the grinding teeth, the first vertical tooth grain and the second vertical tooth grain, the bone incision condition on a patient can be watched by a doctor through the intervertebral foramen endoscope during bone incision, the doctor can conveniently and accurately control the cutting process, and the bone incision efficiency is improved; and moreover, the osteotome head can be stably placed relative to the bone of the patient during bone incision, meanwhile, bone tissue around the bone incision part of the patient can be ground in the bone incision process, damage to the bone tissue of the part not needing bone incision is avoided, and the safety of the bone incision process is improved.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic osteotomy tools, in particular to an ultrasonic osteotome used under a transvertebral foramen. Background technique [0002] Ultrasonic osteotome is a medical device that uses the principle of ultrasonic vibration to perform bone cutting surgery. It cuts accurately and does not damage surrounding tissues in a short time. It is mainly used in some precise orthopedic operations. [0003] However, the current ultrasonic osteotome head mainly adopts a solid structure, resulting in that the tail of the ultrasonic osteotome cannot be seen by the doctor when using the ultrasonic osteotome, which is not convenient for the doctor to accurately control the bone cutting site, greatly reducing the efficiency of the bone cut. The head of the ultrasonic osteotome is relatively smooth, which makes it easy to damage the peripheral tissue of the osteotomy site when the ultrasonic osteotome is used, redu...
