An Ultrasonic Osteotomy Easy to Adjust the Angle

Abstract

The invention discloses an ultrasonic bone knife which is easy to adjust the angle, which comprises a handle and an ultrasonic bone knife. There is a rotating mechanism, the other side of the supporting seat is connected with a connecting rod through a pin shaft, the inner cavity of the supporting seat is located on the right side of the rotating mechanism and is fixedly connected with a positioning rod, under the action of the positioning rod, the The rotation mechanism limits and brakes. One side of the connecting rod is fixedly connected with a sector gear engaged with the rotating mechanism, and the other side of the connecting rod is provided with a locking mechanism. In clinical use, it is convenient to replace the ultrasonic bone knife, saves time and effort during replacement, and reduces the difficulty of operation for medical staff. In addition, it can realize the change of the angle between the ultrasonic bone knife and the handle, which is helpful for doctors to find a suitable angle when cutting the knife, reducing the The complexity of the operation facilitates the operation, which in turn contributes to the success rate of the operation.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to an ultrasonic osteotome convenient for angle adjustment. Background technique [0002] Ultrasonic osteotome is an innovative technology with many features and advantages that traditional manual and electric orthopedic surgical instruments cannot match. Using the principle of high-intensity focused ultrasound (cavitation effect, thermal effect, mechanical effect), a medical device for bone surgery. In some places, it is called an ultrasonic bone therapy device. The knife uses high-intensity focused ultrasound technology, converts electrical energy into mechanical energy through a transducer, and is oscillated by high-frequency ultrasound to vaporize the water in the contacted tissue cells and break the protein hydrogen bonds, thereby removing the bone tissue that needs to be cut during surgery. complete destruction; [0003] Ultrasonic osteotome has broad application ...

AI Technical Summary

Problems solved by technology

At present, although the ultrasonic osteotome has been widely used, there are still some disadvantages. For example, the installation structure of the ultrasonic osteotome is complicated, and it is time-consuming and laborious to replace the ultrasonic osteotome, which wastes the energy of medical staff. The angle between the bone knife and the handle is difficult to change, which makes it difficult for the doctor to find a suitable angle when cutting the knife, which makes it difficult to reduce the complexity of the operation and is not convenient for the operation
